TESSMANNIANTHUS,
AN ARBORESCENT GENUS
OF MELASTOMATACEAE
NEW TO PANAMA!
Frank Almeda?
ABSTRACT
Recent agr o. activity in montane cloud forests of western and central Panama has led to the discovery of two
new species o

ordonii are described, illustrated, compared, and contrasted with similar

cuador, and

In a paper describing new Peruvian flowering
plants collected by the late Günther Tessmann,
Markgraf (1927) proposed the new genus and
species Tessmannianthus heterostemon, to accom-
modate one of the tallest known trees (30-45 m)
among neotropical Melastomataceae. Markgraf's
circumscription of Tessmannianthus emphasized
its unique androecial characters. The connectives
on the larger set of dimorphic stamens are modified
dorsally into biauriculate, ventrally upturned ap-
pendages. The smaller anther sacs are longitudi-
nally bifurcate distally and have connectives that
are prolonged dorsally at the base into bilobed or
deflexed, bifid appendages. These characters, to-
gether with the pentamerous flowers, trilocular cap-
sular fruits, and prevailingly lepidote indument,
define Tessmannianthus as a natural alliance wor-
thy of generic rank.
For nearly fifty years Tessmannianthus was
thought to be a monotypic genus. Wurdack (1975)
described T. cenepensis and transferred the enig-
matic Miconia calcarata Gleason to Tessman-
nianthus, enlarging the genus to three species and
extending its range from Peru northward to Co-
lombia.
Because of its arborescent habit, rainy season
flowering, and evidently limited number of individ-
uals in any one population, Tessmannianthus has

escaped the attention of most collectors. Each of
the species is known from fewer than six collections,
and open flowers of T. cenepensis and mature seeds
of T. heterostemon remain unknown.
The discriminating collecting efforts of Gordon
McPherson in Panama have yielded the first col-
lections of the two new species described here.
mong the six merianioid genera of Melastoma-
taceae now known from Panama (Gleason, 1958;
D'Arcy, 1987), Tessmannianthus is likely to be
confused only with Graffenrieda. The latter is dis-
tinguished by a calyptriform or irregularly ruptur-
ing calyx, dorsally arcuate stamens, and anther
connectives modified into acute dorso-basal spurs.
The Panamanian species of Tessmannianthus do
not appear to be closely related to one another.
They are, nevertheless, readily separated from all
other Central American melastomes by the follow-
ing characters: the small (4-7.5 x 2-6 mm) clawed
petals are retrorsely erose-ciliolate; the larger ven-
trally arcuate anthers open by a pair of ventrally
inclined confluent pores; and each of the bifurcate
anther sacs in the smaller stamens opens by a
dorsally inclined pore.

Distribution. Known only from the summit
area of Cerro Jefe in central Panama at about 850
m, where the new species is evidently an uncom-
mon member of the low cloud forest vegetation. It
grows with but appears to be greatly outnumbered
by the vegetatively similar Cerro Jefe race of Cono-
stegia montana (Sw.) D. Don ex DC.
Tessmannianthus carinatus differs from other
members of the genus in characters of the foliage,
indument, and calyx lobes. The leaves of this species
are leathery and sulcate, with a rounded terminal
acumen that is turned downward. The indument
on young branches, inflorescences, and the ele-
vated primary nerves on lower leaf surfaces con-
sists of a mixture of appressed lepidote hairs and
spreading dendritic or pinoid hairs. The former hair
type is found in all other members of the genus;
the latter is unique to 7. carinatus. The specific
epithet draws attention to the distinctive calyx mor-
phology. Each lobe is beset with a carinate abaxial
keel that forms an apically incurved clawlike tooth
(Fig. 1D).
Tessmannianthus carinatus appears to be with-
out close relatives. Its leathery leaves are vaguely
reminiscent o . heterostemon, which differs
markedly in having larger (9-20.5 x 6.4-13.5
cm) apically rounded obovate blades, shorter hy-
panthia (3-4 mm) with minute caducous exterior
calyx teeth, and elliptic-oblong, papillate petals.

In the size, shape, and indument of its leaves,
T. gordonii most closely resembles 7. cenepensis.
The latter differs in the following characters: anther
sacs of the larger stamens are linear-oblong and
conspicuously retuse or bifurcate distally for about
0.5 mm; anther sacs of the smaller stamens are
bifurcate for the distal two-thirds of their length
and have connectives that are obscurely lobed but
not prolonged into biauriculate appendages; the
ovary is puberulent; the petals are copiously fur-
furaceous-lepidote abaxially; and the hypanthia are
markedly constricted below the torus into a tubular
neck that shortens to a tight constriction on fruiting
hypanthia. Tessmannianthus cenepensis also ap-
pears to differ in other modal tendencies. Its inflo-
rescences are longer (5-8 cm) and more floriferous
than those of T. gordonii, and its petals are broadly
ovate and appear to lack a well-developed basal
claw. The consistency of these latter differences
will become apparent only when better flowering
material is available for study.
This species is named for Gordon McPherson
(1947- ),collector of the type and all other known
Panamanian specimens of this genus. His many
fine collections of trees, shrubs, and epiphytes have
added a number of new and interesting species to
the flora of Panama.

sister group outside Borneo. Nomenclature, descriptions, illustrations, maps, and a key for all species are provided.
Argostemma Wall. in Roxb. is a large, complex
genus with about 220 described species. The re-
vision of the genus will be published in parts dealing
with different geographical areas. About 51 taxa
have been described from Borneo. There is no
treatment covering the whole island. In this study
I have recognized 28 species, of which six are new.
Most of the 28 species are endemic to Borneo,
Ithough six of them were described from speci-
mens collected outside of Borneo. The remaining
22 are typified on Borneo specimens.
Only synonyms typified by specimens from Bor-
neo are listed under the species
During the 1950s, the late Dr. Bakhuizen van
den Brink, Jr. studied the genus for the Flora
Malesiana project. He annotated many herbarium
labels about typifications. I have studied his lec-
totypifications, and in most cases I do agree with
him, and have accepted the lectotypifications which
are published in this paper.
No infraspecific taxa are recognized in this study.
Most species are stenomorphous, and a few species
are polymorphous. Among the latter, Æ. elato-
stemma occurs as two differing populations on Bor-
neo, but since its whole variation outside Borneo
is not yet known, they are not recognized as sep-
arate taxa. The substantial variation in Æ. borra-
gineum is not correlated with geographical distri-
bution and does not reveal distinct evolutionary
lines. Argostemma hameliifolium and A. moul.
tonii form a complex without discrete infraspecific
units. The distinction between the two species is
more or less preliminary. Argostemma densifolium
is dimorphic, but as the variation seems small, I
have treated the two morphs as one taxon.
MATERIALS AND METHODS
All cited specimens including types have been
studied, unless otherwise stated. I have seen ma-
terial from the following herbaria: A, AAU, B, BM,

thers, and ovaries. For endothecial structure, whole
anthers of all species were mounted in Hoyer's
solution for study.
The species are arranged roughly in phyloge-
netic order. Species 1-12 (the 4. parvifolium
group) belong to one evolutionary group, species
13-26 (the A. psychotrioides group) to a second
group, species 28 (4. neurocalyx) to a third group,
and species 27 (4. bryophilum) assumes an un-
certain position within the genus.
The drawings are my own. In the figures (4—
31), all details of plants indicated by the same
letter (B-T) are drawn at the same magnification
and illustrate the same plant part. Hence, if a
particular part is not illustrated, the corresponding
letter is not used in the figure. The branch, indi-
cated by letter A, is drawn twice as large in Figures
7-15, 17, 19-22, 30, and 31 as in Figures 4-6,

SYSTEMATIC POSITION AND
INTERRELATIONSHIPS WITHIN
ARGOSTEMMA
Argostemma is the largest genus of the Argo-
stemmateae (Verdcourt, 1958; B. Bremer, 1987;
Argostemmatideae fide Darwin, 1975, sphalm.,
pers. comm.). The other genus of the tribe is Neu-
rocalyx (B. Bremer, 1979), a small genus endemic
to Sri Lanka and southern India. The sister group
to the Argostemmateae is the mainly Central Amer-
ican tribe Hamelieae (B. Bremer, 1987). These
two tribes form a monophyletic group within the
subfamily Rubioideae.
In Borneo there are 28 species of Argostemma.
About two-thirds of these are endemic. The Bor-
nean species belong to at least th t mono-
AN groups, each having its sister group outside
Borne
The A parvifolium group is represented by
species 1-12, characterized by “radial” endothe-
cium (see morphological notes),
leaves, rotate corollas, a narrowly ovoidal anther
cone, thin and smooth apical appendages, and a
glabrous style with a hardly widened to slightly
capitate stigma. Three species from this group (4.
parvifolium, A. elatostemma, and A. ophirense)
also occur in the Malay Peninsula and on other
Sunda Islands.
e A. psychotrioides group, species 13-26,
is ad by a sturdy connective, umbelli-
form inflorescences, in most species a corolla cleft
to less than half its length, and usually a style much
anisophyllous
longer than the stamens. Most species also have a
"polarized" endothecium (one species cannot be
classified as "radial" or "polarized"), and most
species have an endothecium with distinct cell mar-
gins (see morphological notes). Argostemma ha-
meliifolium, A. moultonii, A. psychotrioides, and
A. borragineum also occur on other Sunda Islands
but not in the Malay Peninsula.
The remaining species, 4. bryophilum (27) and
A. neurocalyx (28), are more isolated. Argostem-
ma neurocalyx belongs to a totally different group
within Argostemma. It is characterized by an apical
leaf rosette and free stamens, of which the anthers
open by pores instead of slits. The group to which
it belongs has a very wide distribution from West
Africa to the Philippines. The systematic position
of A. bryophilum is not yet clear. It does not fit
in any of the groups mentioned above and is part
of a complex of taxa common in the Philippines
and New Guinea.
MORPHOLOGICAL NOTES
Raphides. Raphides are found in most parts
of the plants and can be seen easily in corollas or
in young glabrous stems.
Colleters. On living material the colleters can
be seen easily, but on old dry specimens they are
hardly visible. They are of the standard rubiaceous
type (Lersten, 1975), with elongated axial cells
surrounded by a palisade epidermal layer. The
colleters are found singly or a few together between
the calyx lobes. At each node they surround the
stem in a ring and occur on the adaxial side of the
petiole and at stipule bases. In species with few
colleters in each ring, the colleters are generally
round in outline, whereas in species with a dense
ring of several hundred colleters they are narrow,
often reduced, and almost without a palisade epi-
dermis (Lersten, 1974). The stipules often end in
apical colleters. In Argostemma chaii, with fringed
stipules, each of the processes making up the fringe
ends in a distinct colleter.
Hairs. In Borneo, only A. apiculatum is gla-
brous. The other species are more or less entirely
or partially pubescent. There are no substantial
differences between hairs on vegetative organs and
those on flowers. Normal hairs are monoseriate and
completely septate, with thin to very thick walls,
and they generally do not collapse when dry. They
may occur all over the leaf surfaces or only on (or
rarely only between) the veins. If there is indu-
mentum on the inside of the corolla or on the style,
the hairs are shorter, mostly one- or few-celled and
thinner (Verdcourt, 1958). Another hair type oc-
curs on, e.g., 4. rupestre (Fig. 131) and A. gee-

sinkii (Fig. 141). On the upper leaf surfaces of
these species there are three or five rows of stiff,
pluricellular hairs. One row occurs along the midrib
and the others along the margins, making them
appear more or less serrulate.
Leaf anatomy. | have studied in detail cross
sections of field-fixed material of 4. bryophilum,
A. elatostemma, A. havilandii, A. moultonii, A.
ophirense, A. psychotrioides, and A. rupestre.
Cross sections of young leaves of the species are
generally very similar. With the exception of A.
bryophilum, cross sections of these species can be
described as follows: upper epidermis of one layer
of large, rectangular cells with rather thin walls
and lacking plastids; palisade chlorenchyma of one
or a few layers of small carrot-shaped cells filled
with plastids; spongy parenchyma of a few to many
layers of small to medium-sized cells almost without
plastids; lower epidermis of one layer of large,
rounded cells with thin walls and without plastids;
stomata quite exposed. This type of leaf also occurs
in Neurocalyx (B. Bremer, unpubl.). Argostemma
bryophilum, aberrant in many other ways, differs
from the others in leaf cross section. Its epidermal
layers are thinner with smaller cells, and the chlor-
enchyma consists of large rounded cells with few
plastids.
Species whose lower leaf surface appears white
(e.g., A. rupestre and A. gracile) have more in-
tercellular spaces in the spongy parenchyma than
other species.
Endothecium. The endothecium of Argo-
stemma (Fig. 1) was studied with light microscope
on whole mounts of anthers. The endothecium var-
ies between groups of Argostemma species. In A.
bryophilum and A. neurocalyx, in many ways
aberrant species, only narrow longitudinal bands
of cells close to the stomium have wall thickenings,
while in all other species from Borneo, wall thick-
enings occur in all cells of the endothecial layer.
In the following, the terms endothecium, endothe-
cial layer, and endothecial type will only be used
for those cells with wall thickenings.
The endothecial cells are generally elongated
longitudinally or horizontally compared with the
line of dehiscence and with the anther-length axis,
or rarely they are isodiametric. In Argostemma
the wall thickenings are U-shaped ribs arranged
transversely in relation to the longest axis of the
cell and with their openings toward the epidermal
layer. The ribs end in knobs.
Dormer (1962), Nordenstam (1978), Noel
(1983), and French (1985) have shown the sys-
tematic significance of endothecial structures. This
study shows that different endothecium types occur
in Argostemma and that these types are restricted
to different systematic units within the genus. Dor-
mer (1962) and Noel (1983) presented systems
for classification of endothecial structures. Dormer
(1962) classified endothecial cells in the Compos-
itae as “polarized” or “radial.” In a polarized en-
dothecium the thickenings are concentrated mainly
at the upper and lower ends of the cells, and when
ribs occur they are parallel to the line of dehiscence.
In a radial endothecium the cells are ribbed all
around; on elongated cells the bars are arranged
transversely, parallel to the line of dehiscence. I
have found Dormer's system somewhat difficult to
use with Rubiaceae because the endothecial cells
are different, often elongated horizontally, i.e.,
transversely to the anther-length axis. In Compos-
itae (Nordenstam, 1978; Dormer, 1962; K. Bre-
mer, pers. comm.), when the cells are elongated,
the elongation is parallel to the anther-length axis.
Noel (1983) presented a more general system
which embraces over 500 taxa from different fam-
ilies. He distinguished several endothecial char-
acters, such as size and shape of the cells, orga-
nization of the thickenings, whether a basal plate
and/or ribs occur, and the shape and number of
these. In general, the endothecial cells of Argo-
stemma can be characterized following Noel’s
scheme (1983: 837): cells medium-sized, 27-60
um on the longest side, isodiametric, rectangular
or fusiform; wall thickenings localized; base plate
absent; ribs U-shaped; 5-ca. 15 ribs per cell (in
several species the cell margins become indistinct,
and it is difficult to see where the cell ends); spacing
from close to wide; branching absent; tips knobbed.
gostemma. The first two are e
first type, in A. bryophilum, A. hameliifolium
Fig. 1A), 4. moultonii, and A. neurocalyx, the
cell margins become indistinct, and the endothecial
layer can be described as consisting of long, hor-
izontal, rather narrow bands with many close dis-
tinct transverse ribs and knobs. This type also
occurs in the sister genus Neurocalyx. 1 have ex-
amined the endothecia of Hamelia patens, Hoff-
—
mannia vesciculifera, and Xerococcus congestus,
belonging to Hameliieae, the sister tribe to Argo-
stemmateae (B. Bremer, 1987), and they are of
the same type.
In the second type (e.g., A. enerve, A. gracile,
A. havilandii, and A. psychotrioides (Fig. 1B)),
the cells are horizontally elongated and fusiform
but with distinct cell margins. The ribs are not as
close together, and the knobs are larger than in
the first type.

The third type could be classified as "radial."
This type occurs in many species, e.g., Á. ophi-
rense, A. parvifolium (Fig. 1C), and A. rupestre.
The cells are generally rectangular, with the lon-
gitudinal axis parallel to the dehiscence line. The
cells are larger than in the ““polarized” group. The
transverse ribs are indistinct to hardly visible, and
the knobs are smaller and look like a string of
pearls surrounding the cell margins.
fourth group consists solely of 4. borra-
gineum (Fig. 1 D), whose endothecium is unique at
least among the Borneo species of Argostemma.
The cells are generally isodiametric and large. The
ribs are indistinct, generally arranged parallel to
the dehiscence line, and the knobs are indistinct.
Since the ribs are not transversely arranged in
relation to the anther-length axis, this type cannot
be described as **radial," and since the knobs sur-
round the cells on ie margins, it cannot be de-
scribed as “polarize

cles become erect. These parts and the fruit,
After anthesis the pedicels and pedun-
crowned with the calyx lobes, become fleshy and
succulent. The fruit opens by an apical operculum.
Such fleshy capsules are not uncommon in the
tropics (Ehrendorfer, 1983: 829). Bakhuizen f.
(1975) said about fruits of Rubiaceae:

The fruit of Argostemma does not fit into this
system. Although Bakhuizen f. was an expert on
this genus, he had never seen it in the field (pers.
comm.), and on dry material he had probably mis-
interpreted the fruit type.
When the fruit is open the fibrous endocarp
separates from the remaining pericarp and splits
into threads, which are visible in the opening. The
septum, with the attached placentas, is also fibrous
and will split. Among the resulting threads the
umerous seeds will be exposed. Perhaps the threads
Mii sudden dispersal. It is not uncommon to
find specimens with many seeds germinated within
the capsules. This kind of “vivipary” or germi-
nation in situ is described earlier from Ophiorrhiza
tomentosa (Tan & Rao, 1981).
Placentation. Placentation is axile with the
placentas (Fig. 2) attached at the top of the septum.
he placentas are stalked, pendulous, fleshy, and
in front view broadly ovoidal to kidney-shaped.
Seeds. | Argostemma has numerous, small (ca.
0.5 mm), angular to ovoidal seeds (Fig. 3). The
testa seems to be unique to this genus. The surface
is mostly reticulate with a mamilla or a ring in
each cell.
DISTRIBUTION
The maps (1-28) of Argostemma show that
most localities are from northwestern Borneo. This
is not because Argostemma is more common there,
but indicates that this part, Sarawak, is botanically
most well known. The same pattern can be seen
in Memecylon (K. Bremer, 1983) and other gen-
era. The few localities in Kalimantan result from
comparatively few botanical expeditions, and large
areas of former rainforest have been deforested.
Taxonomically, Argostemma in Borneo belongs
to at least three different species groups which are
more or less sympatric, and many species within
the same group are sympatric. The distributions
of different species of Argostemma are influenced
by altitude, a fact that is hardly evident on the
maps. Argostemma elatostemma, A. densifolium,
A. havilandii, A. cal-
cicolum, A. trichosanthes, A. psychotrioides, and
A. variegatum grow only at low altitude; and 4.
A. gaharuense, A. chaii,
anisophyllum, A. dulitense, A. apiculatum, A.
burttii, A. geesinkii, A. gracile, A. brachyanthe-
rum, and A. brookei grow only at altitudes over
1,000 m. Some species occur at both low and high
altitudes: 4. parvifolium, A. subfalcifolium, A.
ophirense, A. A. hameliifolium, A.
moultonii, and A. borragineum.

of them are sympatric. Of the eight species known

There is a question mark after Java on the label
of the type specimen, and on the label there is also
written “Sumatra,” as is indicated in the proto-
logue. Argostemma parvifolium grows on sand-
stone, sandy banks, and cliffs near streams, from
350 to 1,450 m. The species is based on non-
Borneo material. The habit of the Borneo popu-
lation is similar to the type of A. parvifolium var.
involucratum (Hemsl.) Bakh. f. I have not studied
the complete variation of A. parvifolium outside
Borneo, and so for now I avoid infraspecific taxa.
Except for the inner floral parts, the whole plant
is densely covered by long soft hairs. As in all
Argostemma species, the flowers are slightly pen-
dulous at anthesis, and in this species the flowers
are slightly zygomorphic. The rotate corolla has at
its center distinct green nectar guides on the upper
half. The anther cone is bent upwards and the
stamens, in the upper half of the flower, have
curved filaments. It is the only Borneo species with
these characters.

Hooker based 4. elatostemma on two collec-
tions, by Lobb and Griffith. Both are suitable for
lectotypification. Bakhuizen f. (in herb.) selected
the Griffith specimen in K, and I follow his choice.
Argostemma elatostemma grows in wet shady
forests, from 100 to 750 m. It occurs in the first
division of Sarawak and on the southern tip of
Kalimantan. The collections from these two areas
are different. The Sarawak specimens are alike and
similar to the type collection from the Malay Pen-
insula, while the Kalimantan specimen, described
as A. motleyi, agrees well with the type of A.
elatostemma var. obovata King (1904). In this
study I have not dealt with any infraspecific taxa
because I have not yet studied the complete vari-
ation outside Borneo. The specimen from Kali-
mantan is smaller with shorter leaves, and there is
only one flower in the collection. Argostemma ela-
tostemma is characterized by its creeping habit,
rooting at the nodes, silvery mottled leaves, and
unequal leaf bases. The stems, petioles, veins of
the lower leaf surfaces, and the inflorescences are
densely pubescent. The flowers are rotate with a
long pale anther cone which blackens in the press.

Argostemma subfalcifolium grows in damp
shady places in the lowland rainforest at altitudes
from 100 to 1,500 m. It tends to have subfalcate
leaves. The species is characterized by rather long
calyx lobes and by furrowed fruits. The stems are
glabrate and sometimes slightly pubescent. The
peduncles and lateral branches of the inflorescence
are mostly glabrous, whereas the pedicels, ovary,
and lower part of the calyx lobes are pubescent.
The flowers are rotate, and the buds are distinctly
angular in cross section. The staminal cone is high.
From the outside the thecae are completely shed
by the connectives but can be seen as immerse
sacs between the filaments.
here are a few aberrant specimens. Anderson
4090, from Bako in Sarawak, consists of very small
plants. They were collected on fallen tree trunks
and have a peculiar habit, but no other details
contradict inclusion in this species. Meijer 2286,
from Kalimantan, has nearly cordiform nanophyl-
lous leaves, but otherwise fits. Brooke 9194, from
Sarawak, has very narrow leaves with obscure pri-
mary veins.

There are only a few collections of this species,
and they are in bad condition. The description of
the flowers was prepared from undissected flowers,
and so some information is lacking. The scanty
information on its habitat indicates that it grows
on steep sandstone slopes and on gentle slopes on
litter. It was collected at low altitude in south-
western and northeastern parts of Sarawak and in
Sabah. I have not managed to find the locality
"Bongaya," but according to Steenis-Kruseman
(1950), Ridley visited the Kudat, Sandakan, and
Lubak Bay in 1897, so it must be somewhere in
this area. Ridley (1927) described two varieties of
this species. I agree with him that the two popu-
lations are different. The southwestern population
(Fig. 7A), including the type of 4. densifolium,
has narrow leaves and glabrous inflorescences, while
the northeastern population, including the type of
var. latifolium, has denser foliage with larger,
broader leaves and pubescent inflorescences. In this
study, however, I have chosen not to deal with
infraspecific taxa. On herbarium labels, Bakhuizen
f. has treated these taxa as synonyms of A. ophi-
rense. Argostemma ophirense and its allies are
complex, but A. ophirense and A. densifolium
from Borneo are two distinct taxa, in my opinion.
Argostemma densifolium has a different leaf shape,
denser foliage, and long peduncles.

When Ridley (1912) described A. salicifolium
he stated that the specimens are preserved in the
Singapore Gardens Herbarium. Bakhuizen f. indi-
cated, on the herbarium label, the K specimen as
the type (= holotype). The SING specimen must
be treated as the holotype and the K specimen as
an isotype, as Ridley (1912) said that the specimens
are preserved in SI
Argostemma ophirense grows on ground or on
rocks in forest from 50 to 1,300 m; most collec-
tions are from under 1,000 m.
There is little morphological variation in this
species except for variation in leaf width and dis-
tinctness of foliar veins. It is characterized by in-
dumentum on the stems, petioles, and veins be-
neath. The leaves are generally lanceolate with
oblique bases. The cordiform nanophyllous leaves

Argostemma burttii was found growing at bases
of trees among mosses at ca. 1,300 m. It is a local
endemic species from the Hose Mountains. Mr. B.
L. Burtt has collected it at three different places.

It is a beautiful little plant with very large flow-
ers. The corolla is open and flat with green spots
at the center, and the anther cone is cream-colored.
The border between the filaments and the thecae
is indistinct, as in, for example, 4. apiculatum, A.
rupestre, and A. geesinkii. With the last two it
also shares the character of three or five rows of
stiff, pluricellular hairs on the upper leaf surface.
Argostemma burtii is most similar to A. apicu-
latum, both having large corollas and short apical
appendages, but 4. burtii differs by having ser-
rulate leaves and creeping or suberect habit.

cept for three or five rows of stiff pluricellular hairs
on the midrib and along the margins. The marginal
hairs make the leaves serrulate. The lower surface
of the leaves is pale. The stipules and nanophyllous
leaves are similar in shape. The corolla is cleft to
near the base into narrow and erect-spreading lobes.
The anther cone is high with a pale yellow color
near the base and whitish at the apex. The inflo-
rescences are lax cymes with one to five flowers.
The peduncles and pedicels are narrow and gen-

pubescent on the peduncles, pedicels, and ovaries
and have somewhat broader corolla lobes. There
are two collections from different areas (Brooke
9131 and Richards 2455) with very narrow leaves;
both were collected in or near streams and may
be ecotypes. Clemens 21737 came from an un-

Argostemma gaharuense was collected by Burtt
at 660 m at Bukit Gaharu. Its habit is not given
on the herbarium label.
On the label of the type specimen is written:
"Leaves dark green above, white below. Corolla
white, lobes strongly reflexed. Base of anther cone
green, tips white." It is a small, easily recognized
plant. The leaves are dark and pubescent on the
upper surfaces, and below they are white and gla-
brous. The stems are distinctly branched distally
with many apical inflorescences, each with one to
six flowers in lax cymes. The vascular strand to
each calyx lobe becomes a distinct rib, making the
fruit five-ribbed. The habit is similar to that of A.
rupestre, A. geesinkii, and A. burttii, but A.
haruense differs from these by having monoseriate
leaf hairs, branched stems, and reflexed corolla
lobes. The leaf and stipule shapes are the same as
those of A. geesinkii. The specimen from Gunong
Apeng has narrower leaves than the type, and there
is only one inflorescence with two flowers. However,
it has reflexed corolla lobes and the same kind of
indumentum.

Ridley based 4. hullettii on three collections,
by Haviland and by Hullett. All are suitable for
lectotypification. Bakhuizen f. (in herb.) selected
the single Hullett specimen in SINC, and I follow
his choice. The elevation mentioned in the proto-
logue is indicated only on that specimen.
Argostemma hameliifolium is common and is
widely collected. It grows from low altitude to 2,000
m. Most collections are from sandstone; a few are
from limestone. It grows on boulders or sand in
wet places near streams or waterfalls.
Argostemma hameliifolium is part of a big,
poorly understood complex, which includes 4.
moultonii (see discussion under that species). Ap-

proximately 100 specimens have been referred to
. hameliifolium, all large plants with large, equal,
opposite leaves and more or less erect stems. The
leaves vary in shape and size and in distinctness
of nervation. In a few cases the leaves are very
broad and obtuse; these are similar in appearance
to A. borragineum. The stipules, of which only
the upper first to third pairs are persistent, are
large, ovate to ligulate, and entire or slightly cleft.
The flower buds are narrowly ovate in outline. The
anther cone is high with short, free apical ap-
pendages and generally short filaments. The mar-
gins are longer than the central part and incurved
so that each apical appendage forms an open cyl-
inder. The style is generally hairy with a distinct
capitate and slightly bifid, slightly exserted stigma.
In this treatment I maintain A. hameliifolium sep-
arate from A. moultonii. There are many distin-
guishing characters, though not always constant,
and many specimens are impossible to determine
with certainty. Argostemma hameliifolium is more
erect and has larger vegetative organs. Its anthers
have short apical appendages and shorter filaments.

Bakhuizen f. (pers. comm. and on herbarium
labels) treated 4. parvulum as a synonym of 4.
hameliifolium; he believed it to be a dwarf form.
However, I have found that 4. parvulum is better
accommodated as a synonym of 4. moultonii.
Argostemma moultonii grows in wet, damp
places among mosses on tree trunks, on cliffs, or
on sandy or clayey soil, and a few collections are
from limestone. It grows from low altitude up to
ca. 2,000 m; most specimens are from ca. 1,000 m.
Ridley based A. moultonii on two collections by
Moulton, in K. Both are suitable for lectotypifi-
cation. Bakhuizen f. (in herb.) selected one of the
specimens, Moulton 6695, and I follow his choice.
Ridley based A. velutinum on three collections,
in K, by Haviland, Moulton, and himself. All are
suitable for lectotypification. Bakhuizen f. (in herb.)
selected the Haviland specimen, and I follow his
choice.
Argostemma moultonii and A. hameliifolium
form a complex in which a number of species have
been recognized (see above). This complex is well
defined as a group by unique characters: equal,
opposite leaves; long, glabrous peduncles; pubes-
cent pedicels; corolla cleft to near the base and
with narrow, spreading or reflexed lobes; and con-
nate anthers with distinct apical appendages which
are free in the upper part and have margins longer
than the central parts and incurved to form an
open cylinder. There are at least two species (4.
hameliifolium and A. moultonii) involved in the
complex. | cannot recognize more in spite of the
fact that this group is the most widely collected in
Borneo. There are a few specimens similar in habit
to the highly variable species 4. aequifolium Ridley
(1901) from the Malay Peninsula and Sumatra,
but this species does not have the unique stamen
characters. Specimens similar to the type of A.
hameliifolium, erect, large plants, are referred to
A. hameliifolium, but the rest could be separated
into several variable groups within A. moultonii.
There would be many specimens that could not be
placed with certainty.
Argostemma moultonii needs further eed I
have dealt with it in a manner similar to Dr.
huizen f. (pers. comm.). Argostemma OIM
generally can be characterized and separated from
A. hameliifolium by having a smaller, creeping
habit, generally longer internodes, smaller stipules,
and anthers with long filaments and long apical
appendages. Within 4. moultonii at least six local
populations with distinct morphological characters
can be identified. From some localities different
populations are found without continuous variation
between them. Characters separating these popu-
lations are indumentum of the stems, leaves, and
floral parts and the shape, texture, and nervation
of the leaves. The following examples illustrate this.
At the summit of Mt. Matang the plants (including
the type of 4. velutinum) have ovate leaves with
acuminate apices, distinct primary veins, and long
petioles, and the plants are covered by long hairs.
Close to that locality, at Lundu and Berumput, the
collections (including the type of 4. mjoebergii)
are similar in habit but less pubescent and have
shorter petioles and less distinct veins. At Gunong
Murud several different populations occur. One is

almost glabrous (dry specimens) with very thick,
veinless, elliptic, acuminate leaves and with very
long internodes (Burtt & Martin 5326, Noote-
boom & Chai 1935). Except for the very long
internodes, they are similar to the type of A. par-
vulum from Baram. Another population includes
the type of A. murudense with small, broad, ovate
to rounded, obtuse to acute, densely pubescent
leaves. These specimens are similar to the type of
A. moultonii from the upper Baram. Martin 38848
represents a different population with glabrous, ob-
ovate leaves with distinct prominent veins. From
Ulu Tinjar in Baram, there is a collection (Chai
34832) with glabrous linear leaves. From Mt. Kin-
abalu, there are several different populations—one
(Gardner 88) is glabrous with thick, veinless leaves
but different from the glabrous specimens from
Gunong Mulu. There are also specimens with ovate
to obovate, slightly pubescent leaves. Plants from
Kutei and Gunong Tapa Sia in Kalimantan (Endert
3614, 4238 and Axelius 112B) are small rosettes
with ovate, obtuse leaves having very long hairs.
These collections are similar to Nooteboom 921
from Gunong Alab in Sarawak. Perhaps these rep-
resent something different and distinct from 4A.
moultonii, but based on the scanty material avail-
able, it is impossible to decide.

All specimens are suitable for lectotypification.
Bakhuizen f. (in herb.) selected the specimen in L
and I follow his choice.
Valeton did not indicate any collection in the
protologue of A. streblosifolium. In the Bogor her-
barium (BO) there is only one specimen (Amdjah

huizen f. (in herb.) has selected that specimen, and
I follow his choice.
Argostemma borragineum is one of the most
common Argostemma species from low altitudes
to ca. 2,000 m. It often grows near shady streams.
All notes concerning its habitat place it on sandy,
loamy soil, sandstone, or sedimentary rocks. It is
highly variable. The majority of the plants are
large, to 1 m high, with black and scarred stems.
The opposite leaves are equal, large, and rounded,
and the stipules are broad and distinctive. The
inflorescences are densely pubescent and generally
very large, sometimes with more than 150 flowers.
They commonly develop two or three scorpioid
branches, which become most prominent after an-
thesis. The corollas are cleft for about half their
length into recurved lobes. The stamens are unique.
The entire stamen is coriaceous and (on dry spec-
imens) dark, and no differences can be discerned
between the connective and the thecae, at least
not from the dorsal side. The apical appendages

are separated in a characteristic way. The style is
generally densely pubescent and bears a distinct
capitate stigma strongly exserted. There are also
plants uniformly smaller in all organs except for
the flower, with smooth stems and more densely
pubescent inflorescences, but there are also other
small plants which have scarred stems. Several
different populations have been collected from Mt.
Kinabalu. I have not found any correlation between
the morphological variation and any pattern of
distribution.

Argostemma flavescens is known from only two

there is still a great deal of information missing
about the species. It has a characteristic habit, and
its leaves are densely pubescent, particularly be-
tween the veins. In all other Borneo species the
indumentum is more dense on the veins. The in-
formation on the flowers in the description is taken
from Bakhuizen f. (1953, and pers. comm.). He
placed A. flavescens close to A. borragineum be-
cause of its stamens. In my opinion it is not possible
to determine its closest relatives within Argostem-
ma at this time.

This species is named after Mr. Paul Chai of
the Forest Department, Sarawak. Argostemma
chaii grows on dead wood, wet rocks, or wet ground
in the lowland rainforest, to 300 m. This species
is a very small herb, with leaves more or less
condensed into rosettes. Its primary veins are ob-
scure, and the stipules are broad and fringed api-
cally with colleters. The flowers are characteristic,
with thick corolla lobes and free anthers. The fil-
aments are wide, fixed at the base of the corolla,
and adnate with it for a short distance. The stigma
is discoid.

Argostemma in Borneo
Distributions in Borneo. — 17.
Mars 17, 18.
Argostemma chaii is a rare species collected
from two different areas in Sarawak. The collec-
tions from the 5th Division are hairy on the ped-
icels, calyx, and on the outside of the corolla. The
leaves also have scattered hairs. From the lst
Division the plants (including the type specimen)
are glabrous in all parts. From Mt. Matang in the
lst Division the leaves are distinctly larger than
from other localities.
Bakhuizen f. (pers. comm.) has treated this taxon
as a synonym of A. inaequale (Bennett, 1838).
Their habits are similar, but their flowers are dif-
ferent. Argostemma inaequale does not have the
thick corollas nor the discoid stigma, and its anthers
have long apical appendages, while the anther ap-
pendages of A. chaii are very short.

internodes 2-5 mm. Leaves opposite, very un-
equal, distichous, pale silvery underneath; stipules
persistent, ca. 2 mm long, broadly ovate or cor-
diform to auriculiform, ending apically in a distinct
point; stipules and petioles + fused into an am-
plexicaul sheath. Larger leaves of the anisophyllous
pairs with pubescent petioles 0.5-1.5 mm long;
lamina 0.6-1.7 x 0.3-0.7 cm, oblong to narrowly
oblong or rarely obovate, basally rounded or acute
with the lobes equal or oblique, marginally entire,
apically obtuse or obtuse with a point, or acute,
herbaceous to coriaceous, glabrous or with scat-
tered hairs somewhat concentrated along the mid-
rib on both sides; midrib distinct but without pri-
mary veins. Nanophyllous leaves persistent, 4-5
mm long, ovate. Inflorescences l-flowered, soli-
tary, without peduncle; pedicel 0.2 cm, pubescent.
Flowers 5(or 6)-merous; calyx lobes 2-3 mm long,
triangular to cordiform, pubescent in lower parts;
corolla ca. 8 mm long, cleft less than Y its length,
externally glabrous and internally pubescent only
along the margins of the lobes; lobes broadly tri-
angular, spreading. Stamens ca. 2.5 mm long, free;
anther cells and apical appendage free, not forming
a cone; filaments ca. 14-14 as long as the anthers,
equal, straight; sacs opening completely longitu-
dinally; apical appendages almost absent, thick and
slightly papillose; tive distinct, smooth. Style
ca. 5 mm long, alabrona, with a discáid, bifid stig-
ma, long-exserted. Fruit without furrows or ribs.
Argostemma gracile grows on fallen rotten logs
or on rocks among mosses in submontane or mon-
tane forests from 1,000 to 1,600 m. One collection
(Bremer 1667) is from low elevation, 350 m, in
an area of lowland rainforest with big boulders
covered by mosses.
Argostemma gracile is easily recognized, with
its creeping habit and distichous, anisophyllous
leaves, the nanophyllous leaves above the larger
leaves. The leaves are thick with a distinct midrib
but without other visible veins. They are silvery
white beneath. The petiole and midrib have a few
hairs on both surfaces, but one exception is the
type specimen of A. podochiloides with completely
glabrous leaves. The stipules and petioles are more
or less connate with the amplexicaul sheath. This
character, combined with the glabrous leaves, has
been used for recogniton of 4. podochiloides, a
species not accepted here. Flowers in A. gracile
are solitary on very short pedicels and without
peduncles. The corolla is campanulate with spread-
ing lobes. The stamens are free, and there are
practically no apical appendages. The stigma is
distinctly bifid and discoid.

Argostemma brachyantherum grows in sub-
montane or montane forest between 1,000 and
2,100 m in northeastern Borneo.
This species is generally small to medium sized
with anisophyllous leaves and a few large, cam-
panulate flowers with free, very short anthers. The
indumentum, particularly on the leaves, differs
among the collections, otherwise the species is rath-
er uniform. The specimen Argent & Coppins 1081
is much larger than those of other collections and
also has many more flowers. Some characters of
this specimen deviate from the typical range for
the species and are enclosed in parentheses in the
description.

Argostemma brookei has been collected from
the ground in the forest in the Poi (= Pueh) range
at elevations of 1,000 to 2,000 m.
It is medium sized with oblanceolate, aniso-
phyllous leaves. The upper part of the stems, the
peduncles, and the whole inflorescences are cov-
ered by rather stiff hairs. The length of the calyx
lobes is intermediate between the short ones, most
common among the Borneo species, and the long
lobes of A. psychotrioides.
Most specimens of this taxon have been deter-
mined as A. brachyantherum, another mountain
species, which occurs mainly at Kinabalu. In habit
they are similar, but Argostemma brookei has
many small flowers with deeply cleft corollas having
evidently recurved lobes. The free anthers are long-
er and stand close together, like a cone; the apical
appendages are much longer, and the filaments are
shorter than in A. brachyantherum.

Valeton based 4. lanceolatum on four collec-
tions by Teysmann and Hallier, in BO and L. All
are suitable for lectotypification. Bakhuizen f. (in
herb.) has selected Teysmann 11292 in L, and I
follow his choice.
Bakhuizen f. selected the K specimen of A.
havilandii as the type (= holotype). This is a
mistake because Ridley (191 2) stated that the plants
are preserved in the Singapore Botanical Gardens
(note under 4. ophirense).
Argostemma havilandii has a scattered distri-
bution. Most, if not all, collections are from lime-
stone. It grows from 50 to 1,100 m elevation on
litter or more or less as an epiphyte on tree trunks,
usually in lowland rainforest.
It is easily distinguished. The stem is black on
the upper part (on dry specimens), and the lower
transverse bars. The corolla is cleft to about its
middle into recurved lobes. The anther cone is low
and pale yellow to creamish. The connectives are
distinct, and the thecae are separated from each
other at anthesis. The broad, thick apical append-
ages are connate along their whole length.
Argostemma havilandii is easily circumscribed.
There is little variation among the populations ex-
cept for width and hair cover of the leaves. From
around Gunong Api there is a population with a
very dense hair cover, even more distinctive than
the densely pubescent specimens from Sungei Bika
in Kalimantan, where they have been described as
A. hallieri var. sparsipilum.

This rare species has been collected only four
times. Haviland and Hose made the first collection,
noting only the locality as Baram. Different col-
lectors recorded it as growing on limestone. An-
derson said “frequent in crevices on vertical lime-
stone rocks." My collection is from low altitude in
a limestone area. The earlier collections were a
determined as A. borragineum because of the equal,
opposite leaves. However, the stems, stipules, an-
thers, and style are quite different. It is close to
A. havilandii and shares various characters with
this species: lower stems pale brown to grayish,
these having papery to corky surfaces and elevated
ridges; anther shape; and clavate pubescent styles.
However, Argostemma calcicolum differs from A.
havilandii by its denser pubescence even on the
peduncles and stipules, isophyllous leaves, and the
upper part of the connectives distinctly papillose
to hairy. The hairs on the connectives are not
homologous to those on the anthers of 4. psycho-

Argostemma trichosanthes is known only from
the type. It was collected at Bidang Menabei on
Kalimantan at 700 m.
Argostemma trichosanthes is close to A. havi-
landii and A. calcicolum, with which it shares the
stem characters pale brown to gray, papery to
corky, and with elevated ridges on the lower stems.
With A. calcicolum it shares opposite isophyllous
leaves. Argostemma trichosanthes is easily distin-

Argostemma humifusum has been collected
twice, but nothing was recorded about its habit or
habitat.
This species is characterized by its broad, ob-
ovate leaves and large cordiform stipules. Because
of incomplete material, I do not know the shape
of the corolla. It has a thin corolla similar to those
generally cleft halfway into recurved lobes. Inter-
nally the corolla seems to be glabrous, but among
the other species with thin corollas, the lobes are
usually pubescent. The upper part of the connec-
tive is probably papillose to pubescent as in 4.
calcicolum and A. trichosanthes.

Argostemma psychotrioides is found mostly at
altitudes less than 250 m, although it occurs up
A m. It grows in shady, wet places on
exposed roots and pneumatophores in swampy for-
ests and on boulders in streams. It also grows under
drier conditions on limestone and at higher altitudes
in mossy forests.
It is easily identified by its strongly reflexed calyx
lobes which in living material are green with white
margins and tips. The corolla is thin and pubescent
to densely pubescent and has recurved lobes. The
anther cone is low, pale yellow to creamish. Only
the apical appendages are connate, and the thecae
are free. The thick apical appendages and the back
of the thecae are distinctly papillose to hairy, while
the connectives are smooth (cf. A. trichosanthes).

There is little variation in the characters of the
flowers, but a few specimens (Bremer 1730, 1744,
1748) from the 7th Division have shorter calyx
lobes. The shape and size of the leaves as well as
the occurrence of hairs are variable and do not
correlate with distribution patterns.

this species from all others: the inner pollen sac of

and there is no distinct apical appendage. The
stigma is distinctly clavate with papillae covering

of the seven known specimens), the stigma is totally

water trickles." It is not only the sole collection of
the species on Borneo, it is also the only collection

The La Boca Formation is the third in a series
of three stratigraphically and lithologically similar
formations from the geologically complex Cana
region of Panama yielding well-preserved fossil pol-
len and spores. The Culebra Formation is oldest
(basal) and is overlain by the Cucaracha Formation.
The La Boca does not anywhere lie directly on the
Cucaracha, but it interfingers (viz., is contempo-
raneous) with the Pedro Miguel Formation, which
overlies the Cucaracha elsewhere in the Canal re-
gion. Age estimates are based primarily on mol-
luscan (Woodring, 1957-1982) and ostracod (Van
den Bold, 1972, 1973) data which suggest an early
Miocene age for the three formations.
he La Boca outcrops along both sides of the
Panama Canal from the Pacific entrance to the
Las Cascadas Reach. The sediments were deposited
in an estuarine environment and include an alter-
nating sequence of mudstones, siltstones, sand-
stones, lignitic shales, tuffs (waterlain volcanic ash),
—
and limestones typical of that environmental set-
ting. The presence of the coralliferous Emperador
limestone member in the lower part of the for-
mation and Rhizophora-containing lignitic shales
indicate deposition in warm temperate to tropical,
shallow seas and in adjacent coastal, brackish-water
habitats.
Fifty-four samples were collected from two ex-
posures of the La Boca Formation along the Las
Cascadas Reach in September 1967 (latitude
9°04'N, longitude 79?40'W; ground elevation 52.7
m). Locality A (samples 1-26) was at Canal marker
1600 (1766 in the new marking system), and lo-
cality B (samples 27-54) at markers 1622 (1788),
1625 (1791), and 1627 (1793). Since that time
the Canal has been widened from 90 m to 155 m,
and compared with the present physiography, the
1967 samples were collected about 25 m up and
60 m out over the present Canal. The beds dipped
back into the slope at a 20-25? angle so that now

the same lignite layers are nearly at water level.
Other details of the collecting site and geology of
the area are summarized in Graham et al. (1985:
495-502).
MATERIALS AND METHODS
Extraction and processing techniques are de-
scribed in Graham (1985). Slides are labeled ac-
cording to locality, sample number, and slide num-
ber (e.g., Pan A 5-1). Of the 54 samples collected,
20 contained fair to well-preserved palynomorphs
(locality A—5, 14, 16, 17, 19, 20, 21; locality
B— 27, 28, 29, 30, 33, 34, 35, 45, 46, 47, 50,
52, 54). Location of the specimens on the slides
is by England Slide Finder e (e.g., ESF
C-29). The tabulations in Table 1 are based on
five representative samples (14, E 20, 21, 50)
containing diverse and well-preserved palyno-
morphs. All materials are deposited in the paly-
nology collections at Kent State University.
SYSTEMATICS
Thirty-nine palynomorphs have been identified
from the La Boca Formation (Table 1) in addition
to 15 others that cannot presently be identified
(unknowns 1-15). Most of the specimens have
been recovered from other Tertiary formations in
the Gulf/Caribbean region and discussed in pre-
vious publications, hence the material presented
here is synoptic. These formations and references
are as follows: Gatuncillo (middle(?) to late Eocene,
Panama; Graham, 1985); San Sebastian (middle
to late Oligocene, Puerto Rico; Graham & Jarzen,
1969); Uscari (early Miocene, Costa Rica; Gra-
ham, 19872, b); Culebra (early Miocene, Panama;
Graham, 19882), and Cucaracha (early Miocene,
Panama; Graham, 1988b). Present ranges of the
modern analogs within the Neotropics and ecolog-
ical data are based on field observations, personal
communication with specialists, and the literature,
especially Croat (1978), D'Arcy (1987), Hartshorn
(1983), Tryon & Tryon (1982), and Woodson &
Schery (1943-1980). Terminology for vegetation
types follows Holdridge (1947; Holdridge et al.,
1971), used by Croat (1978) and Hartshorn (1983)
for describing the plant communities of Panama
and Costa Rica. In instances where the modern
analogs extend into South America, their altitudinal
ranges and community affiliations may differ slight-
ly from their Central American occurrences. The
data for Central America are considered first in
paleocommunity and paleoenvironmental recon-
struction of the La Boca flora, since communities
in South America are more distant and were iso-
lated from Central America until about 3 Ma.
FUNGI
Ascomycete cleistothecium (Fig. 1). Flattened,
circular, multicellular, cells cubical, 6 x 9 um,
outer and some lateral walls of peripheral (mar-
ginal) cells thickened, center opaque (solid?), cells
disrupted along outer edge, forming slitlike opening
35 um long (attachment scar?); 124
Reproductive structures of the Plectomycetes
group of ascomycete fungi are frequent in Gulf/
Caribbean Tertiary deposits but never in large num-
bers. Although entire specimens are relatively rare,
fragments are present in almost all samples. Another
type with radially aligned cells and marginal spines
was recovered from the lower Miocene Uscari se-
quence of Costa Rica (Graham, 1987a, fig. 1).
PYRROPHYTA
Spiniferites (Figs. 2, 3). These dinoflagellate
cysts, as fossils referable to Spiniferites, are com-
mon in the Tertiary and extend back to the Early
Cretaceous. They are produced by some species
of the extant Gonyaulax group (Evitt, pers. comm.,
87)
This
is also a common Tertiary form produced by the
modern Gonyaulax grindleyi (= Protoceratium
Operculodinium centrocarpus (Fig. 4).
reticulatum) and a frequent associate of Spinifer-
ites in the Miocene. According to Evitt (pers. comm.,
1987), “These two cyst types are common con-
stituents of Tertiary nearshore sediments. They
occur, virtually to the exclusion of other forms, in
the Miocene Monterrey Formation in California
(Spiniferites much the more abundant), and to-
gether with a very rich associated assemblage in
the Calvert Formation along the east coast. It would
be entirely plausible to find them in estuarine de-
posits of Miocene age virtually anywhere. No ex-
amples of Spiniferites, which has a very distinctive
and easily recognized morphology (at least at the
generic level), have been found in fully freshwater
sediments."

to include nearly all members of the family. The
labels on reference slides used for identification
often reflect this confusion, especially between Cy-
athea and Alsophila. A further complication is
that the lip surrounding the laesurae is difficult to
observe on some fossil specimens because of pres-
ervation and/or orientation. According to recent
illustrations by Gastony & Tryon (1976) and Tryon
& Tryon (1982), trilete, micropunctate forms with
a lip often bordered by punctae are referred to
Cyathea, while forms with a laevigate surface be-
neath the perine belong to Alsophila. Laevigate
spores of similar size and morphology lacking the
lip and bordering punctae are produced by several
extant genera (e.g., species of Adiantum). Follow-
ing this classification, Cyathea spores are known
from the Culebra, Cucaracha, La Boca, and Paraje
Solo formations (as Alsophila in the latter; Gra-
ham, 1976, figs. 16-18). Alsophila is known from
the Gatuncillo Formation (Graham, 1985, fig. 10,
as trilete fern spore type 1) and from the Paraje
Solo Formation (Graham, 1976, fig. 19, as Cy-
athea).
In Central America Cyathea grows primarily in
low rain forests, montane forests, and cloud forests,
usually between 1,500 and 2,000 m

northern Mexico (Nuevo León) and Florida to Ar-

It usually grows at altitudes below 2,000 m in wet,
cloud, or gallery forests. Spores are frequent but
not abundant in the Gatuncillo, San Sebastian, Us-
cari, Culebra, Cucaracha, and Paraje Solo for-
mations.

Antrophyum is represented by about 10 species
in the Neotropics, growing in cloud and rain forests
usually at elevations between 100 and 1,500 m
from Mexico (Hidalgo) through Central America
and the Antilles to northern Argentina and south-
eastern Brazil (Tryon & Tryon, 1982: 360). The
spores are similar to those of Acrostichum aureum
L. (cf. Tryon & Tryon, 1982, figs. 49.10, 12 and
51.8), a species expected in the La Boca and other
estuarine formations because it grows in brackish
straight, narrow, 12-1
mangrove swamps. The spores of 4. aureum in
our reference material (nine collections) have a
granular, scabrate sculpture, while those of An-
trophyum are more laevigate. The distinction is
difficult among fossil specimens, and it is possible
that both genera are represented in Gulf/ Caribbean
Tertiary deposits. Since the fossils are laevigate,
however, they are referred to cf. Antrophyum.
Similar spores are known from the Gatuncillo, San
Sebastian (not figured in Graham & Jarzen, 1969),
Culebra, Cucaracha, and Paraje Solo (as an un-
known in Graham, 1976, fig. 227) formations.
OTHER TRILETE FERN SPORES
Several trilete fern spores were recovered for
which biological affinities could not be determined.
Three of the more distinctive ones are described
below.

rounded, margin entire; trilete, laesurae straight,
narrow, inner margin entire, 12 um long, extending
ca. % distance to spore margin; laevigate; wall 1.5

MONOLETE FERN SPORES
Reniform, monolete fern spores are common in
all Tertiary formations studied for the Gulf/Carib-
bean region. They are produced by members of
the Blechnaceae, Polypodiaceae, and Pteridaceae
and range from Paleozoic to Recent. Five types
illustrate the range in sculpture and size. Type 1
Fig. 18; 45 x 32 um) is laevigate; type 2 (Fig.
19; 70 x 46 um) is finely verrucate; type 3 (Fig.
20; 69 x 51 um) has numerous, small, densely
arranged verrucae; type 4 (Fig. 21; 42 x 36 um)
is coarsely verrucate; and type 5 (Fig. 22; 54 x
36 um) has prominent, widely scattered, peglike
verrucae.
GRAMINEAE

ca. 2 um thick; psilate to faintly scabrate; ca. 3
um (folded) (Fig. 23).
The Gramineae ] and the spec-
imens cannot be referred to MER single genus. Grass
pollen continues to be rare or absent in Gulf/
Caribbean Tertiary deposits studied to date, with
only a few grains previously reported from the
Culebra and Paraje Solo formations. Specimens are
known in the stratigraphic literature as Monopori-
tes annulatus and range from the Paleocene (Bra-
zil) to Recent (Muller, 1981, 1984)
PALMAE
Although several surveys of modern palm pollen
are available (e.g., Ferguson, 1986; Thanikaimoni,
1970), it is still difficult to identify Gulf/Caribbean
Tertiary specimens. The pa
component of the vegetation, and three types are
recognized for the La Boca Formation.
Attalea type (Fig. 24). Wedge-shaped, with
greatest diam. near pole; amb ca. rectangular;
monocolpate, colpus straight, narrow, 19-22 um
long, inner margin entire to minutely dentate; sca-
brate; tectate, wall ca. 1.5 um thick; 43-47 x
25-29 um.
Attalea is a genus of about 40 species occurring
in South America, the West Indies, and the Old
World tropics, with one species (4. allenii H.
Moore) listed for Panama (D'Arcy, 1987), where
it grows at elevations up to ca. 1,000 m
lms were a prominent
Manicaria type (Figs. 25-27). | Prolate, with
greatest diam. at or near equator; monocolpate,
colpus straight to slightly sinuous, narrow, 30-42
um long, extending nearly entire length of grain,
inner margin entire; finely reticulate (diam. of lu-
men | um or slightly less); tectate-perforate, wall
ca. 1 um thick; 36-48 x 21-30 um.
Manicaria is a tree up to 10 m tall, with three
species in the Antilles, Central America, and South
America (fide Bailey, 1943), where it often occurs
in dense groves in wet places. Similar pollen is
known from the Gatuncillo and Culebra formations.
Synechanthus type (Figs. 28, 29). Prolate;
monocolpate, colpus straight, narrow, 30-42 um
long, extending entire length of grain, inner margin
entire; microreticulate; tectate-perforate, wall 1.5—
2 um thick; 36-48 x 30-38 um
Synechanthus grows in Panama at low eleva-
tions in the tropical moist, premontane wet, and
premontane rain forests (Croat, 1978: 178). Sim-
ilar pollen occurs in the Culebra Formation.
AQUIFOLIACEAE
Ilex (Fig. 31). Oblate-spheroidal, amb oval to

In Central America /lex commonly grows at mid
altitudes in moist to slightly drier habitats. It is a
frequent component of Gulf/Caribbean Tertiary
microfossil floras in low percentages and has been
recovered from the Gatuncillo, San Sebastian, Us-
cari, Culebra, Cucaracha, and Paraje Solo for-
mations.

BOMBACACEAE
The pollen of several Bombacaceae are distinct
(Tsukada, 1964; Nilsson & Robyns, 1986), but
other generalized types cannot be referred to any
one genus (see listings in Muller, 1981: 46-48).
There is also some overlap with the closely related
families Sterculiaceae and Tiliaceae, and in fossil
deposits types are recovered that do not match
exactly any extant members of the complex (Gra-
ham, 1976, figs. 248-255). It is possible that some
unidentified pollen represents extant species not
yet collected or extinct taxa from early speciation
after introduction into the Caribbean region. Fur-
ther studies are needed on the pollen morphology
of modern forms, including newly described taxa,
and a complete assessment should be made of fossil
types.
Bombacaceae are prominent members of neo-
tropical forests, and the pollen is frequent but not
abundant in Tertiary sediments. Muller (1981: 46-
48) listed the oldest occurrence of this family as
Maestrichtian (uppermost Cretaceous) from the
southeastern United States and cited other records
supporting Wolfe's (1975) suggestion that the fam-
ily originated in eastern North America and sub-
sequently spread to South America and Africa where
it diversified. In the Caribbean region it first ap-
pears in the Paleocene of northern South America
(Bombacacidites annae = Bombax ceiba type;
Germeraad et al., 1968: 277), and in our material,
pollen of the family occurs in the San Sebastian
Formation and Uscari sequence.

Pseudobombax is a tree to 25 m tall distributed
from Nicaragua to Brazil and Peru. In Panama it
typically occurs at lower elevations in the tropical
moist forest but is also found in the premontane

Pollen of Alchornea is frequent in low numbers
in Gulf/Caribbean Tertiary deposits. It ranges from
the lower and middle Eocene (Colombia; González
Guzmán, 1967) to Recent (Muller, 1981). Its ecol-
ogy and distribution have been summarized by Gra-
ham (1987a) based on Croat (1978) and Webster
& Burch (1967). In Central America Alchornea
grows in the tropical moist, premontane wet, and
premontane rain forest typically at elevations be-
tween 300 and 2,000 m

Solo formations.
LEGUMINOSAE—CAESALPINIOIDEAE
Crudia (Fig. 37, 38). Prolate; tricolporoidate,
colpi narrow, straight, 25 um long, extending near-
ly entire length of grain, equatorially arranged,
meridionally elongated, equidistant, pore area faint,
circular, situated at midpoint of colpus; distinctly

allel to long axis of grain, surface psilate, margins
entire, occasionally appearing beaded from under-
lying pores in foot layer /endexine; tectate but with
occasional separation between sculpture elements,
wall 1.5 um thick; 42-48 x 30-32 um.
Crudia is a South American, mainly Amazonian,
riverine tree of low altitudes (Cowan & Polhill,
1981: 131). Pollen ranges from the Eocene in
northern South America (as Striatocolpites ca-
taumbus) and from the Paleocene in Africa (Mul-
ler, 1981). It occurs in Central America in the
Gatuncillo and Cucaracha formations. Modern pol-
len has been studied by Graham & Barker (1981).

Utricularia is an annual or stoloniferous peren-
nial, insectivorous, aquatic herb growing along the
margins of freshwater lakes and rivers, swamps,
and marshes from Florida to Mexico and south
through the Antilles, Central America, and South
America. It is represented by about 12 species in
Panama (Taylor, 1976). Pollen also occurs in the
Paraje Solo Formation.
MALPIGHIACEAE
Representation of the Malpighiaceae in the Gulf/
Caribbean Tertiary is analogous to the Bombaca-
ceae, wherein several types are present but many
do not match exactly modern reference material
or species illustrated in the literature. Generally
similar modern forms include Banisteria, Banis-
teriopsis, Bunchosia, Hiraea, Malpighia, and
Mascagnia; but since the specimens are slightly
different, they are referred to types 1-

porites estelae, late Eocene to Recent).
RHIZOPHORACEAE

Pollen of Rhizophora has been recovered from
the Gatuncillo, San Sebastian, Uscari, Culebra, Cu-
caracha, and Paraje Solo formations and comprises
90% or more of some samples. Its fossil record
has been discussed by Langenheim et al. (1967),
Leopold (1969), and Muller & Caratini (1977),
and its occurrence in the Gulf/Caribbean Tertiary
was summarized by Graham (1985: 519, 1987a).
Rhizophora is indicative of coastal, brackish-water
Prolate to prolate-
conditions in tropical to subtropical regions. It is
known in the stratigraphic literature as Zonocos-
tites ramonae and ranges from the late Eocene to
Recent. In older Tertiary deposits in Latin America
it is replaced by its presumed ecological equivalent
Brevitricolpites of unknown biological affinity.
RUBIACEAE
The Rubiaceae are represented in the La Boca
Formation by two similar pollen types typical of
several extant genera. These tricolpate, densely
sculptured forms are produced by Anisomeris,
Chomelia, Guettarda, Terebraria, and others.
Type 1 (Fig. 45). Oblate to oblate-spheroidal,
amb circular; tricolpate, colpi equatorially ar-
ranged, meridionally elongated, equidistant, short
(4-5 um apex to equator), often obscured by dense
sculpture; reticulate, muri 1.5 um wide, smooth,
straight to occasionally curved or slightly sinuous,
lumina 2-3 um diam.; tectate-perforate, wall 2 um
thick; 26-36 um.
Type 2 (Fig. 46). Similar to type 1 but is
slightly larger (42-46 um), and the muri are thick-
er (ca. 2-2.5 um
THEACEAE
Pelliciera (Figs. 48, 49). Oblate, amb circu-
lar; tricolporate, colpi equatorially arranged, meri-
dionally elongated, equidistant, 20-26 um, taper-

3-4 um diam., situated at midpoint of colpus, inner
margin entire; sculpture variable from finely to
coarsely verrucate; tectate, wall 4 um diam.; size
variable, 40-60 um
Pelliciera is a small mangrove tree of lowland
coastal areas from Costa Rica to northwest Colom-
bia and Ecuador. In the Tertiary, however, it was
widespread in the Gulf/Caribbean and is known
from the lower middle Eocene Yellow Limestone
Group of Jamaica, the middle(?) to late Eocene
Gatuncillo Formation of Panama, the middle to late
Oligocene San Sebastian Formation of Puerto Rico,
the Oligo-Miocene Simojovel Group of Mexico, and
from several localities in northern South America.
Several anther-size clusters or fragments (Fig. 49)
were recovered, indicating the plants grew in the
immediate vicinity of the depositional basin. The
presence of Pelliciera pollen in the La Boca For-
pon is one of the principal a A between
1l Culebra and C
In the e record it is known as Psila-
tricolporites crassus and ranges from the Eocene
to Recent. Other details of the ecology and geologic
record of Pelliciera have been summarized by
Graham (1977).
UNKNOWNS
A number of specimens were recovered that
could not be identified. Some of the more distinctive
and/or abundant ones are illustrated and briefly
described below.

PALEOCOMMUNITIES AND PALEOENVIRONMENTS
Results of the La Boca study are of interest in
demonstrating an internal consistency in paleocom-
munities, climates, and physiography among four
fossil floras in two countries of Central America,
as well as consistency with independent plate tec-
tonic and paleotemperature data. The lower Mio-
cene Uscari (Costa Rica), Culebra, Cucaracha, and
La Boca (Panama) floras preserve elements of a
mangrove swamp (Pelliciera, Rhizophora) fring-
ing the volcanic islands constituting the isthmian
region during most of the Tertiary. Freshwater
marshes and swamps (palms, ferns, Utricularia)
occupied lowland areas behind the mangrove zone.
On the adjacent slopes were versions of the tropical
wet, tropical moist, and premontane forests (Ly-
copodium, Selaginella, Cyathea, Pteris, Ilex,
Pseudobombax, Alchornea, and Crudia, with Al-
faroa/ Engelhardia likely occupying distant, mod-
erate highlands in the region). All available paleo-
botanical data are consistent in showing little
evidence of dry (including savannah) habitats. Grass
pollen continues to be poorly represented (maxi-
mum of 156 in one sample from the Culebra For-
mation; less than 0.5% in two samples from the
La Boca) to absent (Uscaria, Cucaracha forma-
tions). If savannahs existed, as suggested by the

posits (see further discussion in Graham, 1988b).
he affinities of the La Boca flora are clearly with
Central America and areas to the north, reflecting
the establishment of a land connection between
Central America and South America only about 3
Ma.
The lack of any paleobotanical evidence for sig-
nificant highlands is in agreement with plate tec-
tonic models suggesting that elevation of the early
volcanic islands and peninsulas gradually increased
during the latter part of the Cenozoic, and that the
highest elevations (3,475 m in the western moun-
tains of Panama; 3,820 m, Cerro Chirripo, Costa
Rica) are of recent origin. Altitudes up to about
1,200-1,500 m would accommodate all elements
in the four lower Miocene floras known from south-
ern Central America. No pollen was being blown,
washed, or transported into the depositional basin
to suggest dry vegetation or high altitudes in the
Gatuncillo, Uscari, Culebra, Cucaracha, or La Boca
formations of Costa Rica and Panama. Muller
(1959) demonstrated that pollen from a variety of
inland and upland communities is transported by
rivers and deposited in coastal basins. Palynological
data from Puerto Rico and southern Mexico further
show that many of these habitats, represented by
both wind- and insect-pollinated elements, are in-
cluded in the microfossil record if such habitats
exist in the region.

All taxa identified from the La Boca Formation

have been similar to the tropical conditions pres-
ently prevailing in coastal, lowland, and moderate-
altitude habitats in southern Central America. This
is consistent with paleotemperature curves (Savin,
19777; Savin & Douglas, 1985; Savin et al., 1975)
that show the Uscari, Culebra, Cucaracha, and La

Endemism is also greatest in Pan (15 species). Species-rich regions in Cos Ri and EM ma are Beier c
species complexes contain on
nging species and several species with m
uch dents EN Only one species-
rich group, the P. calophylla group, lacks a continuously wide-ranging member.
Psychotria is a pantropical and subtropical ge-
nus of mostly shrubs but also small trees, herbs,
and even epiphytes. I presently estimate the num-
ber of species to be 1,650, making it the largest
zenus in the Rubiaceae; this includes 700 species
in the Neotropics (my estimate), 250 in Africa
(Petit, 1964, 1966), and 700 in Asia and Oceania
(Sohmer, pers. comm.).
The present state of its infrageneric taxonomy
reflects the lack of understanding of the genus as
a whole; all that can be said with some certainty
is that subg. Psychotria occurs in all three tropical
regions and that each region has one or more
groups distinguishable from subg. Psychotria. In
Tetramerae (Hiern) Petit (1964, 1966); and in
Asia and Oceania, the situation is much more com-
plex (Sohmer, 1977).
The infrageneric uncertainty extends to delim-
itations of Psychotria and related genera; the neo-
tropical genera Mapouria, Cephaelis, Uragoga,
Naletonia, Nonatelia, and Notopleura have been
variously merged with or separated from Psycho-
tria. Most of these genera, if included in Psycho-
tria, fall within subg. Heteropsychotria and are
therefore not relevant here. Mapouria, named by
Aublet in 1775, is more critical. The principal use
of that generic name was by Mueller-Argoviensis
(1876, 1881), who in his Rubiaceae treatment for
Flora Brasiliensis distinguished between Ma-
pouria and Psychotria; the former corresponded
to what is properly considered Psychotria subg.

mark's Psychotria subg. Heteropsychotria, in-
cluding Cephaelis. The discovery by Petit (1964),
reaffirmed by Steyermark (1972), that the type
species of Psychotria, P. asiatica L., falls well
within the Mapouria generic concept makes that
genus obsolete.
Members of Psychotria subg. Psychotria are
distinguished easily from all others in the genus.
Three characters serve to enable recognition of the
subgenus: (1) the leaves are dry red-brown or some-
times dull green, as opposed to bright green; (2)
the stipules are usually sheathing and caducous,
leaving a small, usually pale ridge often with a
fringe of red-brown hairs, as opposed to only slight-
ly sheathing and conspicuously persistent; and (3
the seeds, hemispherical in cross section, have two
longitudinal furrows on the flat ventral surface and
usually four or five (or sometimes an irregular
number of) longitudinal furrows on the rounded
dorsal surface. Psychotria subg. Heteropsycho-
tria has a variety of seed cross sections, none of
which can be confused with those of subg. Psy-
chotria. Additional characters of whole-plant ar-
chitecture show differentiation between the tw
neotropical subgenera (Hamilton, 1985), as ie
mature fruit color, which is almost always red in
subg. Psychotria and usually blue in subg. Het-
eropsychotria. The naturalness and monophyletic
(or at least ““convex””; see Meacham & Duncan,
1987) nature of subg. Psychotria is not in doubt.
In the Neotropics, Psychotria subg. Psychotria
consists of ca. 200 species. It accounts for the vast
majority of Psychotria species in the West Indies,
just under half in Mesoamerica, and perhaps a
third in South America, where subg. Heteropsy-
chotria is most diverse. Psychotria subg. Psycho-
tria in Mesoamerica, the subject of this treatment,
includes 61 species, 15 of which are recently named
(Hamilton, 1988), and eight varieties. | have sorted
the species into eight species-groups; their recog-
nition as sections awaits study of the subgenus
throughout tropical America.
Systematic understanding of species-rich tropi-
cal taxa such as Psychotria, Miconia, Piper, Bac-
tris, Heliconia, and Anthurium is the critical first
step toward understanding geographical patterns
of diversity and processes of diversification in the
tropics. Psychotria subg. Psychotria appears to
be a good index taxon for describing species di-
versity in tropical angiosperms as a whole (see
Biogeography) and therefore provides a diversity
data set of use to conservation planners and natural
resource organizations. From an ecological and
evolutionary standpoint, one hopes that results of
the study of Psychotria can be extrapolated to
other diversified tropical taxa.
MORPHOLOGY AND TERMINOLOGY
In this section, characters and character states
are explained and illustrated only as necessary in
order to eliminate any ambiguity regarding their
use in descriptions and discussions.
HABIT
Habit states, e.g., "shrub" versus “tree,” are
distinguished primarily by size, not by architecture
or shape. Even l-meter shrubs in this subgenus
are usually treelike in having a main trunk and
lateral branch complexes. Architecture of Pana-
manian species of Psychotria (both subgenera) has
been studied (Hamilton, 1985); three basic types
of branching event were found, differentiated by
the number and orientation of new shoots to which
the terminal node gives rise each growing season.
In Type 1 branching, at the terminal node one
lateral meristem gives rise to a relay axis that
elongates the main axis by sympodial substitution.
In Type 2 branching, two (or more) relay axes
arise at the terminal node and remain equal, neither
new axis assuming the same orientation as the axis
that preceded it. Type 3 branching resembles Type
A except m one of the new relay axes assumes
tion as the parent axis. Most species
of subg. Fears shows Type 3 branching in
both the vertical and lateral directions; this serves
as an additional field character for recognizing
members of the subgenus. Two exceptions within
the subgenus— P. limonensis and P. tenuifolia—
show Type 1 and Type 2 branching, confirming
their taxonomic affiliation based on other cha
ac-
teristics (see Infrasubgeneric eee Ar-
chitecture has not been included in the descriptions
because it has not yet been studied thoroughly for
most species in the field
STIPULES
Stipules can provide valuable information as to
interspecific relationships but prove almost worth-
s a source of key characters, since in this
subgenus they are usually caducous, or deciduous.
he two stipules on opposite sides of a node are
frequently united to some degree into a sheath. As
the young stem grows, mechanical pressure forces
the stipules to sever their basal connections to the
stem and subsequently to fall off (Fig. 1). Thus
most herbarium specimens have no stipules re-

subg. Psychotr
maining. The stipule scar consists of a ridge, usually
pale in contrast to the stem, often with a dense
fringe of minute red-brown hairs; the hairs often
fall off shortly after the stipule. Exceptions to the
above are found in the costivenia group, in which
stipules are robust and not sheathing and thus are
often found persisting several nodes from the ter-
minus, and in the calophylla group, in which the
herbaceous and suffruticose species do not grow
sufficiently to force the stipules to break free.
Stipule shape and size vary considerably, with
the general shape, apex, pubescence, an
differentiation providing critical cone be-
tween species and species groups (Fig. 2). Taxa
descriptions include the stipule Lr. along the
stem followed by the maximum widt
LEAVES
Leaf characters are used extensively in this
treatment in keys and as recognition characters.
A single leaf, if examined critically, can suffice to
identify most species in Mesoamerica. Most char-
acter states are unambiguous; descriptive termi-
nology is from Hickey (1979). Blade measurements
are the length followed by the width at the widest
point. Venation character states are observed on
the undersides of the leaf blades.
Secondary vein divergence is the angle formed
at the junction of a secondary vein and the midvein,
measured on the distal (on the leaf) side of the
secondary vein. Most species have curved second-
ary veins, so the tangent at the base of the sec-
ondary vein was estimated and used. Angles were
measured in the middle third of the leaf blade, as
they often become more acute towards the base
and towards the apex.
The character of secondary venation is consid-
ered to have basically three states: eucamptodro-
mous, brochidodromous, and brochidodromous with
a distinct collector vein (Fig. 3). In eucamptodro-
mous venation, the secondary veins near the mar-
gins do not connect one to another in robust sec-
ondary arches or via a collector vein; they instead
become less robust and distinct towards the margin
and are often connected by a series of arches of
tertiary veins (Fig. 3a). If just one connecting arch
maintains the robustness of a secondary vein, the
venation is said to be bod ipsun (Fig. 3b);
consequently, the distinction between eucampto-
dromous and brochidodromous is one of degree,
and many species show both states. (It may be
assumed, unless stated otherwise, that the second-
ary arches are near the blade margin.) Much more

distinct and easily differentiated— enough so to
serve in the first couplet in the species-identification
key—is the third state, brochidodromous with col-
lector vein, in which there is a distinct collector
vein running straight or slightly undulating near
and parallel with the margin (Fig. 3c). (Note that,
in keys and descriptions, the second state, “‘bro-
chidodromous," should be assumed not to include
a distinct collector vein unless it is otherwise stated.)
The arc shape of the secondary veins is also
described, the states being: a) straight, b) constantly
arcuate, and c) straight near midvein then arcuate
near margin.
The axils of the secondary veins often have tufts
of hairs or domatia or sometimes both. The origin
and function of domatia is little understood, but
the minute holes found in domatia of mature leaves
suggest that early instars of some insects may in-
habit the cavities (Fig.

major difference is that in percurrent tertiary ve-
nation the tertiaries joining the secondaries are
more robust than the other reticulate veins, then
considered quaternary veins. Few species, such as
Tertiary veins in subg. Psychotria are generally
either: a) orthogonal reticulate, joining each other
and the secondaries, intersecting at roughly right
angles, or b) percurrent, joining adjacent second-
ladderlike effect between them (Fig.

P. micrantha, have strikingly percurrent tertiary
venation. In several species, especially in the cos-
tivenia group, tertiary veins known as intersecon-
dary veins intersect the midvein between the sec
ondary intersections and run roughly parallel with
the secondaries.
INFLORESCENCES
Inflorescences in subg. Psychotria consist gen-
erally of panicles of cymes, in which the cyme
(dichasium) is the ultimate group of flowers and
the panicle comprises the axes leading to the cymes
(Fig. 6). The degree of branching of the panicle
reflects the maximum branching found in the in-
florescence: 2 degrees indicates that there are pri-
mary and secondary axes; 3 degrees indicates that
there are primary through tertiary axes, etc. (Fig.
6a-c). Similarly, degree of branching of the cymes
is also described (Fig. 6d-f). Cymes are often so
contracted as to be glomerules of flowers. Bracts
and bracteoles are present, though often incon-
spicuous, on the axes; bracts subtend branches of
the panicle, and bracteoles subtend the cymes.
Inflorescence organization provides many of the
most useful characters and so is described in great
detail (Fig. 7). Secondary axes are borne in ranks
along the main axis. The main axis itself is mea-
sured; the distance between the base of the main
axis and the point of insertion of the basal (first)
rank of secondary axes is the peduncle (its length
included in the measure of the main axis). Sec-
ondary axes are usually two or four per rank; often
when there are two or more pairs of axes per rank,
the pairs are differentiated into a longer and a
shorter pair (Fig. 7a). Often a specified node can
have either one or two pairs of axes; measurements
of a single pair are included under “the longer
pair," while measurements of the "shorter pair"
are relevant only when there are two pairs of axes.
Sometimes secondary axes are reduced so that a
cyme or flower cluster appears sessile on the main
axis (Fig. 7b, k). The angle of divergence of the
secondary axes (measured as is that of secondary
veins) can also provide valuable information: species
in the graciliflora group often have ca. 90? angles
of divergence (Fig. 7h), and P. stockwellii shows
obtuse angles of divergence (Fig. 7i), in striking
contrast to the acute angles characterizing most
species.

taxa of moist- and wet-forest plants (Table 1). The
Anthurium pattern (tabulated from Croat, 1983,
1986) is an amplified version of that of P. subg.
Psychotria, with nearly seven times as many species
in Panama as in Nicaragua. Cordia sect. Micran-
thae (Miller, 1985) and Monochaetum (Almeda,

the general trend. Cavendishia (Luteyn, 1983)
and Heliconia with pendent inflorescences (Kress,

Costa Rica but show no secondary center in Mexico
and Guatemala.

diversity pattern of subg. Psychotria represents
that of many species-rich taxa and may therefore
be of value as an index of regional diversity for
tropical flowering plants. The primary value of this
would be in pinpointing areas to which we should
devote conservation effort in order to preserve the
maximum diversity of life. Figure 12, a map of

great differences in diversity that cannot be dis-
missed as collecting artifact. It is also noteworthy

P. olgae, and P. pacorensis. Mountains near the
Colombian border support three more: P. philacra
(Cerro Tacarcuna), P. rosulatifolia (Cerro Mali
and Cerro Pirre), and P. insignis (south of Puerto
Obaldia). Three narrow-ranging species, P. lasel-
vensis, P. sixaolensis, and P. fendleri, are found
in areas of Caribbean lowlands, which have not
been botanized thoroughly. It is beyond the scope
of this treatment to speculate on the causes of
these patterns—e.g., absolute rainfall, topograph-
ical heterogeneity, geological disturbance— but the
pattern suggests that Costa Rica and Panama de-
serve the lion's share of in situ conservation focus
in Mesoamerica.
The biogeographies of species complexes, within
groups, display consistent patterns that suggest
hypotheses as to the course of evolution within the
complexes (see Infrageneric Relationships). Many
species complexes are comprised of one widespread
species, for which the complex is named, plus one
or more species with much narrower ranges: the
Meg quinqueradiata complex (two species),
e P. micrantha complex (two species), the P.
ud complex (two species), the P. costive-
plex (two species), the P
species), the P. chiriquina complex (three species),
and the P. panamensis complex (six species; see
distribution maps in the introductions to each species
group in the Systematic Treatment). Seven wide-
spread species, such as P. carthagenensis and P.

marginata, are not obviously similar to any nar-
row-ranging species. Group 8, the calophylla group,
defies even tentative analysis of affinities: most
species are narrow endemics in Costa Rica and
Panama, with only P. calophylla and P. psycho-
triifolia having somewhat wider ranges. The pre-
dominant pattern of one widespread plus one or
more narrow-ranging species accounts for 35 of
the 61 species and suggests that in each complex
the widespread species may be ancestral to those
with narrow ranges. Careful phylogenetic analysis
of the subgenus throughout the Neotropics is nec-
essary to evaluate this hypothesis.
Each species and variety account in the Sys-
tematic Treatment includes a characterization of
range in terms of habitat and climate. The habitat
classification used is that of Holdridge (1967), par-
ticularly from life zone maps of Costa Rica (Tosi,
1969) and Panama (Anonymous, 1970). The ranges
of many Mexican species are characterized ac-
cording to a vegetation map of that country (Flores
Mata et al., 1971). Climate types are those of
Walter et al. (1960), discussed by Walter (1973);
the particular climate types referred to herein are
six: I equatorial, I(X) equatorial-mountainous, I(H)
equatorial-tropical, II(I) tropical-equatorial, II
tropical, and II(X) tropical-mountainous. Equato-
rial and equatorial-mountainous climates may show
some seasonality of rainfall, but the ratio of pre-
Numbers of species of Psychotria subg. Psychotria per one-degree square. Squares of high endemism
cipitation (in mm) to temperature (in degrees cen-
tigrade) never drops below 2:1 in any month. In
an equatorial-tropical climate, there is a mild dry
season in which the ratio drops slightly below 2: 1
for one or two months, usually around March. In
a tropical-equatorial climate, the dry season is more
extreme, lasting up to four months at the beginning
of the year. The dry season in a tropical or tropical-
mountainous climate usually lasts November
through April, some of those months often having
absolutely no precipitation.
INFRASUBGENERIC RELATIONSHIPS
Formal taxonomic recognition of sections awaits
understanding of the subgenus throughout the Neo-
tropics. For the time being, I have divided the 61
Central American species into eight groups com-
parable to sections. In several cases I refer to
species complexes, which are sets of morphologi-
cally very similar species within a group.
The following key to species groups indicates
major differences among the groups and is pri-
marily didactic; it utilizes characters, such as stip-
ules, that are useful at the species-group level but
less so for species identification, e.g., because stip-
ules are caducous and fruits are often not present.
For species identification, one should use the key
to species in the Systematic Treatment; it relies

largely on leaf and inflorescence characters, which
are most consistently evident.
Following the key are brief synopses of the eight
species groups, including lists of species, geograph-
ic patterns, and noteworthy character states not in
the key. More extensive descriptions, with distinc-
tive character states italicized, plus discussions of
species relationships, biogeography, and breeding
biology will be found at the beginning of each group
in the systematic treatment.

SPECIES GROUP SYNOPSES
Group 1 —carthagenensis group. Species 1-7.
The carthagenensis group comprises seven
species: Psychotria carthagenensis, P. clivorum,
P. lamarinensis, P. micrantha, P. neillii, P. quin-
queradiata, and P. viridis. The Psychotria quin-
queradiata species complex includes that wide-
spread species plus P. which is
endemic to northern Costa Rica. The P. micrantha
complex includes that species plus P. neillii, whose
lamarinensis,
range is restricted to Caribbean southern Nicara-
gua and northern Costa Rica. Psychotria car-
thagenensis, P. clivorum, and P. viridis are all
widespread without obvious close relatives.
In addition to the key characters, members of
this group may be recognized by their seeds having
(3-)4-5 deep longitudinal furrows on the dorsal
surface and 2 longitudinal furrows on the ventral
surface.
Group 2—costivenia group. Species 8-16.
The costivenia group comprises nine species:
P. balancanensis, P. costivenia, P. fendleri, P.
flava, P. grandis, P. horizontalis, P. papantlen-
sis, P. pleuropoda, and P. sylvivaga. The Psy-
chotria horizontalis i^a includes the most
widespread of the nine plus P. fendleri, which is
endemic to Caribbean coastal Panama. The P. cos-
tivenia complex comprises the other seven; P.
costivenia is only slightly more widespread than
P. grandis, with the two sharing noteworthy mor-
phological similarity and overlapping ranges. Psy-
chotria sylvivaga has been collected only in Costa
Rica, and the remaining four species are restricted
to southern Mexico, Guatemala, and Belize.
Distinctive character states, in addition to those
in the key, include a usually conspicuous persistent
calyx in fruit.
Group 3— graciliflora group. Species 17-25.
The graciliflora v bud nine re
in Mesoamerica: P. ba , P. graciliflora, P
jimenezii, P. laselvensis, P. leia P. margina-
ta, P. orosiana, P. parvifolia, and P. philacra.
Psychotria marginata is the most widespread and
frequently collected, and no other species closely
resembles it morphologically. In contrast, the also
widespread P. graciliflora is strikingly similar to
six of the other species (the P. graciliflora com-
plex) that occur more or less sympatrically with it:
P. parvifolia and P. orosiana (Costa Rica and
western Panama), P. laselvensis (Costa Rica), P
bakeri (Los Santos, Panama), P. liesneri (eastern
Panama province), and P. philacra (eastern Dar-
ien, Panama, at higher elevation than P. gracili-
flora). Psychotria jimenezii may belong to this
complex as well.

Members may be recognized by their key char-
acters plus stipules often biacuminate to biaristate,
secondary veins usually brochidodromous and di-
verging 70°—-90°, and inflorescence secondary axes
usually delicate.
Group 4—remota group. Species 26.
The remota group includes several species in
South America but only one of those, P. remota,
in Mesoamerica. An additional recognition char-
acter is the winged inflorescence axes, conspicuous
especially in the fie
Group 5— nervosa group. Species 27-35.
The nervosa group comprises nine species: P.
aguilarii, P. boquetensis, P. chagrensis, P. eryth-
rocarpa, P. fosteri, P. fruticetorum, P. jinote-
ensis, P. mirandae, and P. nervosa. Two species
complexes, those of P. nervosa and of P. cha-
grensis, are discernible; three other fairly wide-
spread species— P. fruticetorum, P. erythrocar-
pa, and P. jinotegensis—do not closely resemble
any others. The P. nervosa complex consists of
widespread P. nervosa and three species of more
restricted ranges, all of which occur allopatrically
with or at range boundaries of P. nervosa:
mirandae in southern Mexico, P. aguilarii in
higher-elevation southern Guatemala, and P. bo-
quetensis in high-elevation western Panama. The
1
P. chagrensis plex includes widespread P. cha-
grensis and the probably derived P. fosteri, which
occurs on Coiba Island, Panama, apparently allo-
patrically with respect to P. chagrensis.
Recognition characters not included in the key
are ellipsoidal to narrow-ellipsoidal fruit, and inflo-
rescences reduced to fascicles of flowers or the
secondary axes in (2-)3 ranks.
Group 6—panamensis group. Species 36-47.
The panamensis group comprises 12 species in
Mesoamerica: P. cascajalensis, P. chiriquina, P.
cocosensis, P. dwyeri, P. hornitensis, P. lundellii,
P. mexiae, P. olgae, P. panamensis, P. sarapi-
quensis, P. stockwellii, and P. trichotoma. The
largest species complex is the P. panamensis com-
plex. It includes one widespread species, P. pan-
amensis, whose var. ixtlanensis may owe its origin
to introgression from P. trichotoma (see under
Systematic Treatment), and five narrow-ranging
species: P. dwyeri (southern Mexico, sympatric
with P. panamensis), P. stockwellii (Costa Rica
and Panama, sympatric), P. cocosensis (Cocos Is-
land, Costa Rica, allopatric), P. olgae (Panama,
+ sympatric), and P. cascajalensis (Panama, sym-
patric). The widespread species P. trichotoma, P.
sarapiquensis, and P. mexiae are of uncertain
affinities; the former two may be closely related to
. panamensis complex. The P. chiriquina
complex includes two species whose ranges do not
overlap (P. lundellii south to El Salvador and P.
chiriquina south from northern Nicaragua) and
one narrow endemic, P. hornitensis from high-
the
elevation western Panama at the eastern end of
the range of P. chiriquina.
Group 7 —tenuifolia group. Species 48, 49.
The tenuifolia group includes only two species
in Mesoamerica, P. limonensis and P. tenuifolia,
both of which are widespread with extensively over-
lapping ranges. The group is characterized by mi-
nute flowers and secondary veins diverging usually
70-90", in addition to the key characters.
roup 8—calophylla group. Species 50-61.
The calophylla group comprises 12 species: P.
alfaroana, P. calophylla, P. chitariana, P. dress-
leri, P. hammelii, P. insignis, P. insueta, P. mon-
teverdensis, P. pacorensis, P. psychotrüfolia, P.
rosulatifolia, and P. sixaolensis. Ten of the species
have small geographic ranges; only P. calophylla
and P. psychotriifolia are at all widespread, and
their ranges are notably discontinuous. Psychotria
dressleri and P. rosulatifolia are quite similar mor-
phologically and occur in eastern Panama, and
therefore may be supposed to be related; but be-
yond that the affinities are very uncertain.
Additional recognition characters are many: her-
baceous or suffrutescent habit; usual general pu-
bescence; sheathing stipules, these usually bifur-
cate or biaristate with the extensions often from
corners of the truncate sheath; and ellipsoidal fruit.

doaxillary, panicles of cymes or of glomerules or
rarely fascicles of flowers; secondary axes borne
in 1-several ranks along the main axis, each rank
with 1-3 often size-differentiated pairs of axes.
Flowers small, (4—)5-merous, almost always disty-
lous; corolla usually white, the tube cylindrical;
style 2-branched, the branches bearing the stig-
matic surfaces, the ovary 2-celled, the ovules 1
per cell, attached basally. Fruit fleshy, maturing
red (except reportedly purple or blackish in
insueta and P. pacorensis); persistent calyx often
conspicuous at distal end of fruit; seeds 2, hemi-
spherical in cross section, the rounded dorsal sur-
face with 3-5 regular to many irregular longitu-
dinal furrows, usually giving the dried fruit a costate
aspect, the flat or slightly concave dorsal surface
with (1—)2 regular longitudinal furrows often plus
several shallow irregular furrows.
A pantropical subgenus of approximately 600
species worldwide, including ca.
enus accounts for the majority of species in
ihe Antilles but only for 32 of 242 species treated
by Steyermark (1972) for the Guayana Highland.

FIGURE 13. Distributions of Psychotria carthagenensis (circles) and P. viridis (triangles) in Mesoamerica.
Of the seven species in the group, four are
apparently normally distylous and one, Psychotria
viridis, is homostylous (at least in Mesoamerica).
The two remaining species are too little collected
to determine whether they are distylous or thrum-
monomorphic.

collection by Vahl, from the type region of Car-
tagena, resides in Berlin (Willdenow 4083) and
has been annotated as P. carthagenensis; it is,
however, P. nervosa and is clearly not the type
of Jacquin's species.
Psychotria carthagenensis may be recognized
by its obovate leaves drying dull red-brown, eu-
camptodromous secondary venation (Fig. 3), sec-
ondary inflorescence axes in two unequal pairs per
rank (Fig. 7a), corolla drying red, ellipsoidal fruit
drying reddish, and seed in cross section with the
car-
comm.). A
orsal surface having four deep furrows and the
ventral surface having two deep furrows (Fig. 10a).
It is expected that careful analysis will reveal that
this species exhibits more primitive character states
than any other neotropical species in the sub
Mexican and Guatemalan collections suggest that
the leaf blades are larger there than elsewhere in
Central America.

onm clivorum may be recognized by its
elliptic leaves drying red-gray to gray-green, sec-
ondary veins well-spaced and diverging 55°-70°,
inflorescence eea axes in two unequal pairs
per rank, the higher ranks decreasing
formly, corolla drying i ellipsoidal fruit, and seed
cross section with four deep longitudinal furrows
on the dorsal surface and two deep longitudinal
furrows on the ventral surface. Psychotria clivo-
rum shares many character states with P. car
thagenensis, but the former differs in having sti-
pules often biaristate, larger elliptic (versus obovate)
leaf blades, more secondary veins, often brochi-
dodromous secondary venation, and larger inflo-
in size uni-
rescences.
Stipule morphology varies geographically, as
Guatemalan plants appear more often biaristate
while Nicaraguan plants have exceptionally large
stipules. Secondary venation is generally eucamp-
todromous, but in Nicaragua the secondary loops
are sufficiently robust to appear brochidodromous.

Psychotria lamarinensis may be recognized by
its large, broad-elliptic leaves with the base nar-
rowly subcordate, reduced globose inflorescence
drying red-brown, and broad-ovate stipules. Psy-
chotria lamarinensis may be a local derivative
from P. quinqueradiata, from which the former
differs in having much larger leaves with secondary
veins diverging 709-85? instead of 45°-60° and
shorter (3 mm vs. 4-5 mm) corolla tubes.
Only a short-style flower morph has been seen,
but only two flowering collections do not suffice to
suggest that the species is thrum-monomorphic.

Psychotria neillii may be recognized by its great
resemblance to P. micrantha and its delicate fer-
rugineous-pubescent inflorescence axes. Psycho-
tria neillii differs from P. micrantha in having
smaller (10-18 vs. 20-32 cm long) mature leaves
with fewer (12-15 vs. 20-26) secondary veins,
delicate inflorescence axes, and larger (5-7 mm
vs. 4 mm long) fruit.
All three flowering collections are thrums; ad-
ditional collections are necessary to determine
whether the species is distylous or thrum-mono-
morphic.

The glabrous, obovate leaves drying red-brown
to green-brown, with secondary veins usually
brochidodromous making loops far from the mar-
gin, also aid in recognition. Psychotria quinque-

Psychotria viridis may be readily recognized
by its inflorescence: all ranks of secondary axes
except the first and second are reduced so that
flowers and fruit appear in clusters along the main
axis (Fig. 7k). Psychotria viridis is, in its vege-
tative and fruit characters, almost identical to P.
carthagenensis; the distinctive inflorescence may
be viewed as a reduction in secondary and tertiary
axes of that of P. carthagenensis.
There appears to be only one flower morph, a
homostyle, in Central American P. viridis, with
no spatial separation between the exserted anthers
and stigma. Leaves in Guatemala and Belize have
fewer secondary veins than elsewhere in Central
America.
GROUP 2. THE COSTIVENIA GROUP
Shrub or tree; young stems glabrous or puber-
ulent or rarely tomentose or ferrugineous-pubes-
cent; stipules usually not sheathing, ovate, uniform
color or often with a pale central triangle or
keel (Fig. 2b), glabrous or puberulent or ferrugin-
eous-pubescent or sometimes fringed, caducous or
often persistent at terminal 2-6 nodes. Leaf blades
elliptic or ovate or obovate or oblanceolate, drying
usually yellow-green or sometimes green, green-
brown, or red-brown, often dull or pale, sometimes
chalky above, sometimes darker below; T
veins (6-)7-19(-21) pairs, er (45
85°, eucamptodromous or We 5 the
axils usually lacking domatia or duis (except some-
times P. horizontalis and P. sylvivaga); tertiary
veins orthogonal reticulate or less commonly per-
current, the intersecondaries often conspicuous,
the tertiary loops sometimes evident (P. fendleri
and P. horizontalis). Inflorescences panicles of
cymes or rarely of glomerules (P. flava), pedun-
culate (except rarely in P. horizontalis); second-
ary axes usually in 2 or 3 size-differentiated
pairs per rank (Fig. 7b) or sometimes 2 or rarely
4 subequal; bracts not conspicuously enlarged (to
5 mm long in P. flava and P. pleuropoda). Corolla
tubes 2-3.5 mm long (4-5 mm in P. papantlen-
sis), the lobes without apical extensions. Fruit when
dry spherical to ellipsoidal (sometimes slightly ob-
ovoid in P. flava); persistent calyx a beak or a
tube Fig. 9b) or of linear lobes (Fig. 9e) or not
evident, over 1 mm long only in P. fendleri and
P. horizontalis; dorsal seed surface with 3-5 reg-
ular (Fig. 10b) or 6-15 irregular longitudinal fur-
rows (Fig. 10i, j), the ventral surface with 2 often
incompletely divided longitudinal furrows (Fig. 10e)
or one often T-shaped longitudinal furrow (P. flava;
Fig. 10j) rarely plus 4 irregular longitudinal furrows
(P. sylvivaga).
This subgroup may be subdivided into two species
complexes. The Psychotria horizontalis complex
includes the widespread P. horizontalis and P.
fendleri, the latter endemic to Caribbean coastal
Panama (Figs. 16, 17); they share the distinctive
character states of immediately caducous stipules,
brochidodromous secondary venation with con-
necting loops far from the blade margin plus evident
tertiary connecting loops, and persistent calyx at
least 1 mm long. The P. costivenia complex, which
includes the remaining seven species, has in com-
mon often persistent stipules usually with a paler
central triangle or keel, often conspicuous inter-
secondary veins, and persistent calyx a beak or
tube no longer than 1 mm. Two species are wide-
spread— P. costivenia (Mexico through Nicara-
gua; Fig. 18) and P. grandis (Guatemala through
Panama; Fig. 19), both also in the Greater An-
tilles—and five have small ranges: P. balanca-
nensis (Tabasco, Mexico; Fig. 19), P. flava i
ern Mexico and Petén, Guatemala; Fig. 17), P
papantlensis (southern Mexico through Belize; Fig.
16), P. pleuropoda (southern Mexico through Be-
lize; Fig. 17), and P. sylvivaga (central Costa Rica;
Fig. 17)
Of the nine species in the group, six appear
distylous; two of those, Psychotria papantlensis
and P. pleuropoda, show some between-morph
asymmetry in floral part lengths. Only one species,
P. fendleri, apparently has evolved a derived state,
thrum-monomorphy. Too few specimens of P.
lancanensis have been seen to determine its breed-
ing system.

type collection from eastern Balancan, Tabasco, in
a region of evergreen forest and savanna with
equatorial-tropical climate. It was collected in flow-
er in early June.
Known only from the
Psychotria balancanensis may be recognized
by its moderate-sized (7-11 cm long) broad-elliptic
leaves drying dull green to green-brown with con-
spicuous intersecondary veins and by its inflores-
cence with the secondary axes in two ranks near
the apex of the main axis. This species differs from
P. costivenia in having broader-elliptic leaves and
smaller inflorescences with fewer (two vs. four)
ranks of secondary axes.
Only the pin morph has been collected, but the
one flowering specimen seen is not sufficient to
suggest that the species is pin-monomorphic.

Psychotria altorum has been reduced to a va-
riety within P. costivenia because the distinguish-
ing features (see varietal key) are not sufficient to
distinguish a species, though varietal recognition is
useful.
Leaf blades of this variety appear to have more
secondary veins in Mexico than in Guatemala; per-
sistent calyces are beaklike in Mexico and not
evident in Guatemala.

Psychotria miradorensis, described from Mex-
ico, is indistinguishable from P. costivenia, de-
scribed from Cuba; the latter name was published
only a few months prior to the former.
Leaf blades from Zelaya, Nicaragua, at the
southern end of the geographical range, have 15-
18 secondary veins, numbers rarely reached in the
rest of the range. Inflorescences tend to be smaller
in Honduras, El Salvador, and Nicaragua than
farther north. The corolla appears generally wider
(2 mm) in Honduras than in the rest of the range.

Psychotria fendleri may be recognized by its
coriaceous, moderate-sized (7-9 cm long) leaves
usually drying chalky yellow-green and with broch-
idodromous secondary venation suggestive of that
of P. horizontalis. Psychotria fendleri is distin-
guished from P. horizontalis, from which it may
be a localized derivative, by its coriaceous leaves
and chalky color when dry.
The eight flowering specimens examined are all
thrums, suggesting that the species is thrum-mono-
morphic.

Psychotria flava may be recognized by its large
elliptic leaves drying chalky yellow-green to green-
brown and by its large panicles of glomerules with
three unequal pairs of secondary axes per rank
(Fig. 7b). It differs from P. costivenia in having
much larger leaves, glomerules instead of cymes
in the inflorescence, and 6-10 irregular (vs. 4-5
regular) longitudinal furrows on the seed dorsal
surface and one T-shaped (vs. two) longitudinal
furrows on the ventral surface (Fig. 10j).

from Belize, Guatemala, and adjacent Honduras
near the Caribbean coast and also from Nicaragua—
Panama, where it reaches the Pacific side. It occurs
also in the Greater Antilles—Cuba, Jamaica, His-
pañola, and Puerto Rico—and Colombia, Vene-
zuela, and Ecuador. In Central America this species
ranges in elevation 0-2,000 m, reaching over 500
m only occasionally, and is found in tropical moist
to premontane rain forest with equatorial to trop-
ical-equatorial climate. Psychotria grandis has
been collected in flower almost exclusively March-
July and in fruit throughout the year, especially
August-January.

Psychotria grandis may be recognized by its
large size (to 10 m tall), robust keeled stipules with
margins reflexed and usually persistent at terminal
3-6 nodes, large (17-32 cm long) leaves with
conspicuous intersecondary veins, large robust in-
florescences, and fruit drying spherical and smooth,
the latter due to the seed dorsal surface having
many shallow irregular furrows instead of few deep
furrows (Fig. 10i). The distinction between this
species and P. costivenia 1s somewhat problematic,
as it Is based largely on quantitative characters,
such as leaf and stipule and inflorescence size.
Differences in seed cross section (10-15 irregular
vs. 4-5 deep regular furrows on dorsal surface)
support the distinction. The two species occur sym-
patrically only in northern Guatemala and southern
elize.
General puberulence is common only in Belize
and Honduras. Material from Belize has the longest
stipules; Guatemalan material has the largest in-
florescences; and Nicaraguan fruit is generally larg-
er than elsewhere.

S,
All the species in synonymy have been properly
synonymized before (cf. Dwyer, 1980). Infraspe-
cific categories are not recognized herein because
they have been defined in terms of variation seen
within almost any population, such as the basicor-
date leaf blades on which P. horizontalis subsp.
basicordata was based.
Psychotria horizontalis may be recognized by
its leaves drying usually dull pale green, with sec-
ondary veins brochidodromous and making con-
necting arches far from the margin (Fig. 3b), and
by its fruit with conspicuous persistent calyx of
long, linear lobes (Fig. 9e)
Material from Guatemala, Belize, and Nicaragua
is generally more pubescent than elsewhere in Cen-
tral America. The calyx lobes, prominently persis-
tent in fruit, are often much shorter in central
Panama than elsewhere.

Psychotria papantlensis may be recognized by
its elliptic long-petiolate leaves drying pale green
and by its calyx drying conspicuously pale in flower
and in fruit, when it contrasts markedly with the
black-drying ellipsoidal fruit (Fig. 9b).
As in several species, the corolla tube of the
thrum flower morph is longer than that of the pin
morph (5 mm vs. 4 mm); but the species appears
otherwise normally distylous.

Psychotria pleuropoda may be recognized
readily by its narrow-oblanceolate (length/ width —
8-10) leaves unique in subg. Psychotria in Me-
soamerica. It differs from P. costivenia by having
very narrow leaf blades and inflorescences with
relatively short secondary axes in only 1-2 (vs.
ca. 4) ranks. The persistent calyx tube in fruit is
also distinctive.

DIANTHOVEUS: A NEW

Exploration of tropical wet forests in southern
Central America and northwestern South America
in recent years has greatly increased the number
of collections and species known from these areas.
This was especially predictable for the Cyclantha-
ceae, which are restricted to the wettest, often
least-explored habitats (Grayum € Hammel, 1982).
Since the time of Harling's (1958) monograph,
which included 178 species in 11 genera, 29 new
species have been added to this predominantly epi-
phytic family. More than 30 additional new species
are now known from Central America and the
Chocó region of South America alone (Hammel,
unpubl.). However, only one new subgenus (Wilder,
1978) and no other supraspecific taxa have been
described. In fact, in recent years only 10 genera
have been recognized; Pseudoludovia is thought
to be a mixed collection: a spadix, perhaps of a
Sphaeradenia, and leaves of Ludovia (Wilder,
1978). Harling suggested that on further study it
might be possible and logical to subdivide the three
largest genera into additional genera, and for
Sphaeradenia this reclassification is imminent (R.
Eriksson, in press). Dianthoveus, the name an
anagram of “Evodianthus,” is a totally novel,
monotypic genus.
This plant was first described and illustrated, as
a short-stemmed terrestrial, in The Flora of the
Río Palenque Science Center (Dodson & Gentry,
1978), where it was identified as Asplundia va-
gans Harl., a common root-climbing epiphyte of
Central and South America. Examination of spec-
imens of Cyclanthaceae in the herbarium at the
Marie Selby Botanical Gardens, where vouchers
for the Rio Palenque florula are deposited, revealed
that the plant was neither poorly illustrated nor a
terrestrial form of A. vagans, but rather something
problematic, exhibiting unusual characters of sev-
eral genera. This stimulated two field trips to Ec-
uador, which, along with laboratory studies, con-
vinced us that the plant is an undescribed genus.
MATERIALS AND METHODS
In total, well over 200 individuals in seven pop-
ulations were examined in the field. Plants at var-
ious stages—from early anthesis through ripe in-
fructescences to peduncle remains—were fixed in
or anatomical and morphological studies.
Twenty-eight fluid-preserved collections at these
stages were made, and numerous herbarium vouch-
ers and live plants were collected. In the field, live
specimens were examined to determine inflores-
cence position, presence/absence of latex, drying
qualities of wounded and air-dried leaves, and fea-
tures of leaf color and texture.

Dianthoveus
Plants preserved in the field in FAA were drained
of fluid and transported in sealed plastic bags within
a large plastic container. Subsequently they were
washed in water for several days and then stored
in an aqueous solution of 5% glycerin and 50%
ethanol. All measurements were taken from live or
fluid-preserved plants at populations along the Río
Pilatón (Hammel & Wilder 16058, 16059, 16066,
16067 & 16074). Leaf measurements were taken
from a total of 17 adult leaves from three individ-
uals. Inflorescence measurements were taken from
four individuals, and flower measurements come
from ten flowers in each inflorescence. Infructes-
cence measurements were from ten individuals, and
fruit measurements from ten fruits in each of four
individuals. For anatomical studies, material of lam-
inae, roots, and stems was prepared according to
the methods of Wilder (1985). Seeds were taken
from mature preserved infructescences embedded
in Tissue Tek OTC polysaccharide compound, fro-
zen, and sectioned in a cryostat. Sections were
mounted, stained with toluidine blue, and viewed
with a bright field microscope. Pollen was prepared
with and without acetolysis and with and without
critical point drying, coated with gold, and viewed
with a Hitachi S45D scanning electron microscope.
Detailed studies on the morphology and develop-
ment of vegetative parts and inflorescences, and
the anatomy of laminae, first-order roots, and rhi-
zomes are in progress (Wilder, unpubl.).
In order to test our initial hypothesis of rela-
tionship of the new genus to Evodianthus we se-
lected 22 characters for the 11 genera of Cyclan-
thaceae (Table 1), developed a character-by-taxon
matrix (Table 2), and analyzed the data using PAUP
for microcomputer, a maximum parsimony tech-
nique (Swofford, 1985). All characters were un-
weighted, but the four character states of “habit”
were restricted to a specific order (Table 1 and
discussion below). Since no logical basis was ap-
parent for restricting the order of character trans-
formations of other multistate characters, all other
characters were treated as unordered. Characters
with variable states for a particular genus were
coded as missing (Pimentel & Riggins, 1987). Aut-
apomorphies for each of the genera were not in-
cluded in the analysis.
Collections made in December 1988 were added
in proof and not considered in the counts and
measurements.

Paratypes.
Dianthoveus cremnophilus is robust, short-
stemmed, and terrestrial (Fig. 3) but, as indicated
by its epithet, it is a “cliff-loving” plant (Fig. 4).
At many of the sites along the Rio Pilatón we were
able to collect plants only by pulling ourselves up
nearly vertical slopes, using roots and stems as
hand holds. Several large populations, including
the type, were growing on dripping and mossy rock
walls. All of the sites were along small streams or
gullies or on wet, shaded slopes in isolated patches
of relatively undisturbed forest. Even at Río Palen-
que, where the terrain is essentially a rolling plain,
exposed by recent inns of forest cover and showed
signs of sun dam

Ecuador, it seems not to occur outside of that area.
Attempts to find it have failed on the Amazonian
side of the Andes in southern Colombia near Mocoa
in Putumayo Province, and in the Pacific lowlands
of southern Colombia (near Barbacoas) in habitat
similar to that of the adjacent Ecuadorian localities.
Phenology. Nearly all of the collections of
Dianthoveus have been made from June through
December, which spans the primary dry season for
humid areas of northwestern Ecuador (Dodson &
Gentry, 1978). Our search of numerous large pop-
ulations at five different localities during June re-
vealed four phenological classes: (1) most plants
bore no outward sign of fertile structures (N — ca.
200) except for some with old peduncle stubs; (2)
next most abundant were plants with remnants of
old infructescences, primarily long-rotten pedun-
cles (N = ca. 30); (3) we saw and collected only
12 individuals with young to mature infructes-
cences, and (4) five individuals with immature to
old inflorescences. At the type locality, only fruiting
plants were observed in December of 1986 and in
June of 1987. The single mid wet season collection
has a young infructescence. Individuals apparently
bear a single inflorescence per rhizome at one time.
Our studies suggest that Dianthoveus flowers and
fruits sporadically throughout the year. From the
relatively frequent plants with peduncle remnants
during June, we infer a somewhat higher flowering
frequency during January through March, i.e., in
the middle of the rainy season, a common pattern
in other Cyclanthaceae.
Development and morphology of fertile struc-
tures. The peduncles are most flexible at the base
and are held erect at anthesis by the tightly over-
lapping leaf sheaths. Later, as the infructescence
becomes heavier, the elongating peduncle bends so
that the mature infructescence is held either hor-
izontally or nearly pendent. The peduncle is per-
sistent long after the fruits have been shed, and
plants are often found with the fibrous remains of
peduncle firmly attached to the rhizome. Both con-
spicuous and inconspicuous spathes persist into very
late flowering stage with the largest, lowermost
spathe persisting longest. Spathe scars are indis-
tinct.
The fruits of Dianthoveus remain green or be-
come light brown at maturity and apparently offer
little attraction to dispersers; they are neither fra-
grant nor very juicy. We found seeds germinating
in the debris of an old infructescence at the base
of a plant, and often seedlings were found on wet
rock walls below the mother plants. Such gravity
or "flush dispersal” is probably usual for the genus;
however, we found several fruits on one infructes-
cence with the distinctive prints of bat teeth. In
Evodianthus the berries become bright pale orange
and very juicy at maturity and are undoubtedly
dispersed by birds or bats.
Staminate flowers are tightly crowded among
the pistillate flowers throughout development and
persist into the early stages of fruiting; remains of
the pedicels can be found even among mature
fruits. Tepals often vary in length within one flower
and usually with a tendency for the longest tepals
to be together, making the flower slightly asym-
metrical. This asymmetry, however, appears to be
random with respect to the associated pistillate
flower; the longest tepals, for example, may or may
not face the pistillate flower. The tepals are thin
and become brown at anthesis. They are always
without resin glandules.
Tepals of the pistillate flowers are quite similar
in shape and texture to those of the staminate
flowers, an unusual condition for the family. Their
apices are thin, nearly filamentous, and at first lie
closely appressed to the stigmas and to the stamino-
dia. In fruiting stages the tepals become much
broader—only acute to rounded—and the tips often
break off, leaving an irregular ridge around the
stigmas, which no longer protrude and are often
turned upward rather than uncinate. The sides of
the fruit converge basally towards the long axis of
the spadix into a narrow, vertical, lenticular shape.
Relationships. A simple comparison of the
new genus with others in the family suggests that
it is closely related to Evodianthus. Most notably,
both genera and no others have leaves that are
scabrous when dry. Anatomically, this translates
into “styloid sacs [which] are normally elongated
in all directions within the mesophyll, routinely
crossing cell layers" (Wilder, 1985). All other Cyc-
lanthaceae with styloid sacs have them elongated
only parallel to the longitudinal files of parenchyma
cells and confined to one layer. Only Evodianthus
and Dianthoveus have styloid sacs in roots. Pollen
of both genera is the smallest in the family and
inaperturate (Figs. 5, 6), in contrast to the aper-
turate pollen of all other genera. Both genera have
very short or no filaments and lack basal bulbs.
Both have unicostate or cryptically subtricostate
leaves, separate fruits, symmetrical staminate flow-
ers, and terminal inflorescences, characters un-
usual in the family but shared with other genera
(Table 3).
Features of staminate flowers and seeds have
been especially important for delimiting supra-
specific taxa within the Cyclanthaceae (Gleason,

1929; Harling, 1958; Wilder, 1978). In the new
genus, characters of both these structures differ
markedly from those of Evodianthus, from which
the former differs by its lack of a biseriate perianth
(unique to Evodianthus), its lack of a funnelform
receptacle in the staminate flowers (found in Evo-
dianthus and several other genera), and by its only
moderately flattened and narrowly elliptic seeds
(Fig. 7). Evodianthus, as well as Asplundia and
Thoracocarpus, have broadly elliptic, strongly flat-
tened seeds. The seed coat structure also differs
markedly from that of Evodianthus (see below).
The new genus is further distinguished by the eglan-
dular, acuminate tepals of the staminate flowers
(which are similar only to those of Dicranopygium
subgenus Gleasonianthus), the apiculate laminar
appendages of the anthers (shared only with Schul-
tesiophytum), and especially the peculiar papillate
receptacle of the staminate flowers (Fig. 8).
Seed coat structure is variable among genera of
Cyclanthaceae and was an important consideration
in Harling's delimitation of genera in the family.
We have interpreted the wall layers by focusing
on the inner and outer cuticles, described by Har-
ling and present in all genera. The seed coat of
Dianthoveus (Fig. 9) is similar to those of Car-
ludovica and Thoracocarpus; the innermost layer
of the outer integument in all three genera has
relatively large thin-walled cells with spinulose wall
ingrowths on the inner tangential walls, whereas
Evodianthus lacks these spinules (Harling, 1958:
38-43)
Evodianthus occurs rarely as a terrestrial plant
and rarely with leaf blades nearly as large as those
of the new genus. With fresh material, the less
glossy (more satiny) aspect of the upper leaf sur-
face, the larger size, and constantly terrestrial and
short-stemmed habit of Dianthoveus distinguish it
vegetatively from Evodianthus. Due to the simi-
larity of these two genera, Evodianthus specimens
(and all other Cyclanthaceae) at COL, F, MO, QCA,
and SEL were examined to see if the new genus
was included among them; it was not.
PHYLOGENETIC ANALYSIS
The Cyclanthaceae are widely considered to be
monophyletic (Dahlgren et al., 1985; French et
al., 1983), and for the most part each of the 11
genera also has at least one clear apomorphy sup-
porting its monophyly. Within Cyclanthaceae, Cy-
clanthus possesses many unique and highly derived
features (Dahlgren et al., 1985; Harling, 1958;
ider & Harris, 1982) and apparently shares
only ancestral characters with other genera. The

hus, as a starting point we accepted a sister
group sons for the two subfamilies of Cy-
clanthaceae and postulated hypothetical ancestor
for the Carludovicoideae based on the presumably
ancestral characters of Cyclanthus, the only genus
in the Cyclanthoideae. Cyclanthus contains only
two species and is monomorphic for the characters
analyzed; variability within the hypothetical ances-
tor was therefore not a problem. Characters not
obviously comparable between the two subfamilies,
e.g., floral symmetry (Cyclanthus lacks distinct,
meristic floral units at maturity) were coded either
by looking outside the family to the Araceae, Are-
caceae, and Pandanaceae, where Harling and oth-
ers have indicated the most likely affinity with the
Cyclanthaceae, or by designating them as missing
characters for Cyclanthus
Harling's (1958) lecum relationships among
genera in his *Asplundia group," which would
include the new genus, by his own admission were
quite tentative (Fig. 10). The main purpose of our
analysis was to make an explicit statement as to
the placement of Dianthoveus within the family,
using characters from Harling and new characters.
Discussion of those aspects of the character anal-
ysis not directly pertinent to the new genus and
comparison of the phylogeny produced with these
methods to that of Harling will be presented else-
where (Hammel, unpubl.).
Character coding. Several characters were
coded as missing in Cyclanthus, the hypothetical
ancestor for this analysis. For example, althoug
the pistillate **units" seem to demonstrate a re-
markable extreme of fusion among parts, they
readily dehisce from each other at maturity. Fur-
thermore, it is difficult to judge an immediate an-
cestral state for this character from outgroup com-
parison; fruits are commonly fused in Pandanaceae,
that whe g
(1983) sd "iudei c fruits" as a possible syn-
apomorphy for their Areciflorae complex (Areca-
ceae, Cyclanthaceae, Pandanaceae), the berries in
most species of Cyclanthaceae are dehiscent by
apical caps (Thoracocarpus, all but one species of
Asplundia, and most species of the Sphaeradenia
group; Hammel, unpubl.). Live, mature infructes-
cences of Pandanaceae, especially Freycinetia,
need to be examined for comparison.
Characters of the staminate flowers were like-
wise difficult to polarize with reference to Cyclan-
thus, which at maturity has only amerous rows of
stamens. Pandanaceae also have amerous and ape-
talous staminate inflorescences. Flowers were cod-
ed as primitively symmetrical by reference to Ar-
aceae and Arecaceae. Presence/ absence of glands
on tepals and shape of perianth were coded as
missing data.

acter problematic; genera of the Carludovicoideae
have either orthodistichous (in a few species spi-
rodistichous) or spiral phyllotaxy. The Pandana-
ceae have tristichous phyllotaxy. For this analysis
spiro- and orthodistichy were both subsumed under
the category "'distichous," and phyllotaxy was cod-
ed as having only two states. The terminal inflo-
rescences of Cyclanthus seem well supported as
ancestral; terminal inflorescences are the rule in
Araceae (Ray, 1987 and pers. comm.) and in Pan-
danaceae (Tomlinson & Wilder, 1984) and are
characteristic of the “primitive” coryphoid palms.
In palms, however, terminal inflorescences are nev-
er evicted by axillary shoots (Tomlinson & Wilder,
1984). States for seed characters were coded di-
rectly from Cyclanthus as ancestral; the similarity
of seeds of Cyclanthus, Dicranopygium, and Lu-
dovia with those of some members of the Pan-
danaceae is one of the main features that Harling
(1958) saw as indicating a close relationship be-
tween Pandanaceae and Cyclanthaceae.
The branched order of character states for **hab-
it" (Table 1) is rationalized by the observation that
variable taxa almost always include terrestrial
members. It then seems unlikely that any nonter-
restrial form was derived one from another.

Become different possibilities for states coded
as "missing" or different interpretations of prob-
lematic characters for the hypothetical ancestor,
such as fruit fusion and phyllotaxy, this relationship
remains unchanged even when the overall topology
changes.
The highly corroborated sister-group relation-
ship between Evodianthus and Dianthoveus allows
a rational discussion of homologies of the unusual
staminate flowers in the new genus. On the basis
of our hypothesis (Fig. 11), Dianthoveus appears
to retain more relatively primitive character states
than Evodianthus, such as the terrestrial (vs.
climbing) habit. The moderately flattened seeds are
also relatively primitive as compared with the
strongly flattened seeds of Evodianthus. The lam-
inar-apiculate anther appendages of Dianthoveus
could be symplesiomorphous with those of Schul-
tesiophytum, but that assumption would require
an additional step; it is more parsimonious to as-
sume that this kind of anther evolved independently
in the two genera. The biseriate perianth of Evo-
dianthus—an apomorphy for Evodianthus not in-
cluded in the analysis— appears to be derived with-
in the family.
From this basis we can argue that the inner
cycle of the biseriate perianth of Evodianthus might
be an elaboration of the unusual papillate recep-
tacle of Dianthoveus. By this hypothesis, the lobes
of the inner perianth of Evodianthus are not ap-
pendicular organs (leaf homologues), but rather

emergences, equivalent developmentally to the pa-
pillae, which compose cupules in Dianthoveus.
In all cases, regardless of coding, eglandular
staminate tepals appear to have arisen twice within
the Carludovicoideae—in Dicranopygium subge-
nus Gleasonianthus and in Dianthoveus. How-
ever, according to Harling (1958; see also Wilder,
1978), the eglandular tepals of subgenus Gleason-
ianthus are not “real perianths,” but rather are
homologous with stamen filaments; he found that
lobes of this ““false perianth" sometimes bear re-
duced anthers. In addition, the filaments of anthers
in subgenus Gleasonianthus are somewhat flat-
tened and acute, resembling the lobes of the false
perianth. In Dianthoveus we see no equivalent
basis for hypothesizing a staminodial nature for the
eglandular tepals. We found none with reduced
anthers, and they certainly bear no resemblance
to filaments of stamens (Dianthoveus lacks fila-
ments). Based on their position, they appear simply
to be homologous with the glandular outer whorl
of the biseriate perianth of Evodianthus and the
"real perianth” of other Cyclanthaceae. Under this
reasoning, the eglandular tepals of Dianthoveus
are similar to those of Dicranopygium subgenus
Gleasonianthus only by convergence.
CONCLUSION
Before our cladogram or any other is presented
as a phylogeny for the family, several of the char-
acters and character states need to be re-evaluated
and the hypothesis tested with additional charac-
ters. For example, the character of spathe position,
crucial for placing Dicranopygium in the clade
definied by clustered spathes, is somewhat subjec-

together than many species outside the clade. Which
other, if any, multistate characters (e.g., seed shape)
might logically be ordered? One also wonders if
characters such as inflorescence position and phyl-
lotaxy, which seem to encompass a large suite of
characters, should be given extra weight or broken
into several characters. All of this needs to be
evaluated within the context of a hypothetical
ancestor postulated on the basis of taxa outside the
Cyclanthaceae.
though a close relationship between Dian-
thoveus and Evodianthus was suggested initially
by the observation that only these two have sca-
brous leaves, a phylogenetic analysis using parsi-
mony demonstrates the hypothesis as supported b
numerous characters. It also provides a logical basis
for suggesting the El homologies of the
unusual floral features of t ew genus, in par-
ticular, the papillate je (possibly homolo-
gous with the inner perianth of Evodianthus), the
laminar apiculate anthers (evolved in parallel to
those of Schultesiophytum), and the eglandular
tepals (convergent with those of Dicranopygium
subgenus Gleasonianthus).

sarrollan y maduran antes que los carpelos y per-
sisten, sin caerse, después de que los frutos se han
dispersado.
El androceo està formado por tres anteras (una
flor entre cincuenta y cuatro observadas poseia
cuatro anteras). Las anteras son biloculares, y la
pared de la antera inmadura está formada por tres
capas: la epidermis, el endotecio, y el tapetum (Fig.
2). El tapetum desaparece en la antera madura
(Figs. 3, 4). Los estambres no poseen vasculari-
zación. El grano de polen maduro posee tres células
(Fig. 5). La dehiscencia de las anteras es introrsa

Se observó que las anteras se de-
Gineceo. El gineceo es apocárpico. La ori-
entación de los carpelos es variable, de tal manera
que la mayoria de ellos no tiene el estilo en el lado
orientado hacia los estambres, en el centro del
receptáculo. El estilo parte de la región superior
del carpelo en el mismo lado que corresponde al
hilo de la semilla (Fig. 8).
Cada carpelo contiene un solo óvulo sésil, basal,
anátropo (Fig. 7), y bitégmico; ambos tegumentos
son biestratificados, y el interno forma el micrópilo.
El desarrollo del endospermo es de tipo nuclear, y
el endospermo maduro posee células de paredes
gruesas (Fig. 9). El embrión más desarrollado que
se ha observado posee dos células; el cigoto se
dividió transversalmente (Fig. La cubierta
seminal tiene una capa con inclusiones en forma
de partículas.
El fruto es indehiscente. La epidermis del fruto
posee células globosas cuando está en antesis.
DISCUSION
Las estructuras reproductoras de Lacandonia
schismatica son comparables a las mencionadas
por Tomlinson (1982) y por Maas y Rübsamen
1986) para la familia Triuridaceae.
La dehiscencia introrsa de las anteras es una
caracteristica que define esta especie. Sin embargo,
—
el hecho más conspicuo, y nunca antes mencionado
para Triuridaceae u otras angiospermas, es la posi-
ción central del androceo con respecto al gineceo
(Cronquist, 1981). Esta disposición se observa más
claramente en cortes medianos de botones florales
inmaduros
La continuidad celular, en especial la epidér-
mica, que se observa con los tejidos del centro del
receptáculo es la prueba más fehaciente de su
posicion. Sin embargo muchos detalles de la for-
mación del óvulo y la semilla se desconocen y aun
no se sabe que tipo de embrión representan. La
germinación no ha sido observada. Se pone de
manifiesto la necesidad de realizar estudios em-
briológicos, además de estudios anatómicos com-
parativos de especies de la familia Triuridaceae.
Tales resultados contribuirán a ubicar filogenéti-
camente a esta familia y dar luz sobre el Pap d
evolutivo de la inversión en la posición de los ór
ganos reproductores.

Actinostachys germanii Fée, y Guzmania lin-
gulata (L.) Mez var. minor (Mez) L. B. Smith &
Pittend, entre otros. Vive sobre substratos de ma-
teria organica muy humedos, pero no inundados,
en lugares muy sombreados con poca oscilación de
temperatura. La localidad tipo se sitúa en el ex-
terior del borde de la reserva de Montes Azules,
área que se talará para crear potreros.
Fenología. Florece todo el año si las condi-
ciones de humedad son adecuadas. Muy abundante
en noviembre y diciembre, después de la temporada

Lacandoniaceae comparte con Triuridaceae los
siguientes caracteres: gineceo apocárpico, óvulos
anátropos, polen inaperturado, flores trímeras, té-
palos con apéndices, hábito saprofítico, y micorri-
zas endotróficas. Sin embargo, difiere por: a) La
disposición espacial de los órganos reproductores,
con los estambres ocupando la parte central de la
flor. Tal posición no habia sido contemplada antes
para angiospermas (A. P. de Candolle, 1813;
Hutchinson, 1959; Takhtajan, 1969; Cronquist,
1981). b) La dehiscencia introrsa de las anteras,
extrorsa en Triuridaceae (Tomlinson, 1982; Maas
& Rübsamen, 1986).
El análisis cromatográfico comparativo entre
Triuris sp. y Lacandonia schismatica indica cla-
ras diferencias en el tipo de metabolitos secundarios

Cronquist (1981) colocó en el orden Triuridales
a las familias Petrosaviaceae Hutchinson y Triuri-
daceae Gardner. Petrosaviaceae comparte con La-
candoniaceae la dehiscencia introrsa de las anteras,
el hábito herbáceo, y la micotrofia, pero difiere
por presentar estomas, tépalos en dos series, car-
—
pelos fusionados basalmente con muchos óvulos,
nectarios septales, y granos de polen monosulcados.
Dahlgren et al. (1985) consideraron en Triuri-
dales únicamente a Triuridaceae.
La relación espacial que presentan los órganos
reproductores es difícil de explicar a la luz de los
conocimientos actuales. En ausencia de informa-
ción previa, se están llevando a cabo estudios anató-
micos (Márquez-Guzmán et al., este tomo) y fito-
químicos que ayuden a esclarecer su posición
taxonómica.
El nombre genérico está dedicado a la región
Lacandona, asiento del pueblo Lacandón, en el
estado de Chiapas, México. El epíteto especifico se
refiere a los problemas que origina su morfología
en la sistemática.

Recognizing the close phenetic relationship of subg. Heterocharis to the rest of Eucharis, the high levels of al si
within the cladogram, and ambiguity caused by missing character state data, a less parsimonious phylogeny is accepted
as the basis for classification. Keys and descriptions are provided for all species of Eucharis and Caliphruria. Eucharis
caucana, a novel hexaploid (2n — 138) species, is described from Colombia.
The closely related genera Eucharis Planchon
& Linden and Caliphruria Herbert (Amaryllida-
ceae), the Amazon lilies, comprise respectively 17
and 4 species of bulbous, rain forest geophytes
adapted to the low light conditions of the forest
understory. Together with the Peruvian endemic
Urceolina Reichenb., nom. cons., Eucharis and
Caliphruria form a monophyletic group delimited
by petiolate leaves with distinctive cuticular stria-
tion; a turgid seed with a lustrous, usually black
testa; and complete fidelity to the rain forest under-
story niche. The species are distributed from Gua-
temala to Bolivia. The major center of distribution
for Eucharis is in the western Amazon basin (in-
clusive of major tributary systems, e.g., the Napo,
Pastaza, and Huallaga) and the adjoining lower
slopes of the eastern Andean cordillera. With the
exception of single Peruvian species, Caliphruria
is restricted to the Cordillera Occidental and Cor-
dillera Central of Colombia. The species of both
genera are nowhere abundant, and are found grow-
ing only in primary, rarely secondary, forest from

Eucharis and Caliphruria
ca. 50 to 1,800 (rarely to 2,000) m elevation on
soils of high fertility. Large-scale deforestation has
proven catastrophic to these plants, which are un-
able to adapt to the higher light intensity of the
clearings and soon perish. At least several species
are probably extinct, and this number will only
increase with time as rain forest destruction con-
tinues unabated.
The Amazon lilies are marked by their ever-
green, petiolate leaves; white, often pendent, some-
times fragrant flowers with a frequently conspic-
uous staminal cup or false corona formed by the
basal connation of the staminal filaments; obtusely
trilobed stigma; and large, turgid, globose or ellip-
soid seeds with a black, brown, or metallic blue
testa. Eucharis amazonica Linden ex Planchon is
widely known in horticulture, often erroneously as
E. grandiflora Planchon & Linden (Meerow &
Dehgan, 1984a). Neither genus has ever been crit-
ically treated in the taxonomic literature. Baker
(1888) provided a key and descriptions for all
species known at the time in his Handbook of the
Amaryllideae, and Macbride (1936) treated the
known Peruvian species of Eucharis for the Flora
of Peru. Though species of Eucharis have contin-
ued to be described well into the present decade,
the delimitation of these species from previously
described taxa has consistently remained vague.
No assessments of variation at either the population
or species level have been attempted.
As two of only three genera of neotropical Ama-
ryllidaceae (the other being the related Urceolina)
exhibiting complete fidelity to a primary rain forest
niche, systematic understanding of Eucharis and
Caliphruria offers important information relating
to the evolution of the pancratioid Amaryllidaceae
(“infrafamily Pancratioidinae" Traub (1957,
1963)),* centered in the central Andean region of
South America.
No taxonomic scheme can encompass all of the
information about the group of organisms under
study (Holsinger, 1984, 1985; Ornduff, 1969; Ra-
ven, 1 . In genera such as Eucharis and Cal-
iphruria, rare in the wild and often accessible only
with difficulty, and which often exhibit cryptic pat-
terns of variation, this observation becomes much
more acute. By accumulating data from as many
diverse sources as possible, I have attempted to
construct an evolutionary systematic classification
of the Amazon lilies that is both practical yet re-
flects their evolutionary relationships as accurately
as these data allow.
MATERIALS AND METHODS
FIELD STUDIES
Fieldwork was conducted in Peru and Ecuador
in July-August 1982, and in Colombia and Ec-
uador in July-August 1984. Herbarium specimens
and living material were collected, and ecological
observations of natural populations were made.
ANATOMICAL STUDIES AND
SCANNING ELECTRON MICROSCOPY (SEM)
Material was prepared and examined as de-
scribed in Meerow (1987c)
CLADISTIC ANALYSES
Cladistic analyses were run using PAUP version
2.4.1 by David L. Swofford (Illinois Natural History
Survey). All species (and two subspecies) of Fu-
charis and Caliphruria (22 evolutionary units,
EUs) excluding hybrid taxa were analyzed using
forty-one characters (Tables 1—3). For analyses
with PAUP, global branch swapping with the MUL-
PARS option was used in all dep for the most
parsimonious cladograms. Because of the unavail-
ability of material, all desc n. species of Urceo-
lina could not be included in the analysis. Urceo-
lina was therefore entered in the analysis at the
generic level, with character state data drawn from
study of living material of U. microcrater Krànzlin
and specimens of U. urceolata (Ruiz & Pavón)

states were determined from examination of living
and dried material. Character state polarities were
assessed via outgroup comparison (Maddison et al.,
1984; Watrous & Wheeler, 1981). Selection of
outgroups is discussed later with the results of the
analyses
Of ihe 41 characters used in the analysis, 23
were simple, two-state characters. The 18 remain-
ing multistate characters (14 three-state, 2 four-
state, | five-state, and 1 six-state) were treated in
preliminary analyses as unordered (Fitch, 1971;
Hartigan, 1973) using this option of PAUP, rather
than attempting to create any a priori transfor-
mation series. This resulted in a preponderance of
weak monophyletic groups based on single apo-
morphies and/or character state reversals, as well
as unresolved polytomies among many terminal
taxa. In the analyses presented, 11 of these char-
acters were treated as ordered transformation se-
ries (the remaining seven as unordered), with one

ditive binary. Justification for these treatments is
discussed with the results of the analyses. Multistate
characters were adjusted to equal weight with two-
state characters using the "weights scale" option
of PAUP. Additionally, an alternative hypothesis
of generic relationship was tested by submitting a
user-coded tree topology to PAUP for analysis.
HERBARIUM STUDY AND LIVING MATERIAL
Loans or gifts of herbarium specimens were re-
ceived from the following herbaria: AAU, B, BM,
COL, CUVC, F, FTG, G, GB, GH, GOET, HUNT,
K, LE, M, MG, MICH, MO, MPU, NA, NY, OXF,
P, QCA, S, SEL, SP, U, UC, US, VEN.
Neither Eucharis nor Caliphruria is well rep-
resented in herbarium collections, and critical mor-
phological characters are often obscured by the
drying process. Consequently, a living collection of
over 100 accessions representing fifteen species
and several hybrids was accumulated from botan-
ical gardens, individuals, and field collections by
myself and various colleagues. Vouchers for living
material are listed with specimens cited for each
species.
TAXONOMIC HISTORY
Herbert (1844) described the new genus Cali-
phruria from collections made in New Granada
(Colombia) near Guaduas by Hartweg, placing Cal-
iphruria in the “section” Pancratiformes of ““sub-
united by the single character of staminal conna-
tion. The small, white, funnelform flowers were
marked by the presence of a bristle or slender tooth
at either side of the filament. Herbert (1844) made
no mention of basal connation of the filaments. The
orthography of the name, a single "I" in the Greek
stem *'calli-," was emended by subsequent workers
(e.g., Baker, 1877), but was returned to Herbert's
original by Meerow & Dehgan (1984b).
Planchon & Linden (1852) introduced another
new pancratioid genus, Eucharis. The first species
described, E. candida Planchon € Linden, col-
lected in New Granada by M. Schlim, was char-
acterized by its crateriform flowers with a con-
spicuous staminal cup and a widely spreading
perianth limb. If these authors were aware of Cal-
iphruria, they did not note any relationship be-
tween it and Eucharis.
Bentham & Hooker (1883) placed Caliphruria
and Eucharis in the tribe Cyathiferae. Caliphru-
ria subedentata Baker was combined with Eucha-
ris in their treatment, while C. hartwegiana Herb.
was retained. Baker (1888) accepted this treat-
ment, yet described another new species as C.
tenera. He described Caliphruria as "nearly allied
to Eucharis.”
Baillon (1894) described the species C. castel-
naeana and declared it precisely intermediate be-
tween Caliphruria and Eucharis. He further sug-
gested that Eucharis should be treated as a section
of Caliphruria. Macbride (1931) later transferred
C. castelnaeana to Eucharis.
Nicholson (1884) transferred C. hartwegiana
(the type species of Caliphruria) to Eucharis,
ignoring the former's nomenclatural priority. Traub
(1967) made the formal transfer of the remaining
species of Caliphruria, C. tenera Baker, to Fu-
charis and combined the monotypic genus Pla-
giolirion Baker with Eucharis. He had previously
listed Caliphruria, Plagiolirion, and Mathieua
Klotzsch (another monotypic genus) as synonyms
for Eucharis in his Genera of the Amaryllidaceae,
citing Baillon (1894) as a “special reference"
(Traub, 1963: 74). The nomenclatural priority of
Caliphruria Herbert was overlooked. No proposal
for the conservation of Eucharis Planchon & Lin-
den over Caliphruria Herbert has ever been pro-
posed previous to that of Meerow & Dehgan
Traub (1971) later combined Eucharis with Ur-
ceolina, a small Andean genus with petiolate leaves
and markedly urceolate, brightly colored flowers.
He designated five subgenera: Urceolina, Eucha-
ris, Caliphruria, Mathieua, and Plagiolirion.
Traub (1971) offered no explanation for the com-
bination of Eucharis and Urceolina, but presum-
ably his decision was prompted in part by reports
in the literature of two intergeneric hybrids between
Eucharis and Urceolina: x Urceocharis clibranii
Masters, an artificial hybrid, and x U. edentata C.
H. Wright, putatively discovered in Peru. Plagi-
olirion and Mathieua are monotypic genera allied
to Hymenocallis Salisb. and Stenomesson Herbert
respectively (Meerow, 19872).
VEGETATIVE MORPHOLOGY
BULBS
The globose or subglobose bulbs of Eucharis
and Caliphruria, composed of concentric and
modified leaf bases (scales), are characteristic of
most members of the Amaryllidaceae. The bulbs
are sympodial in growth habit (Arroyo, 1984). The
outer scales of Kucharis and Caliphruria bulbs
are modified into an either brown or tan paper
tunic. The bulb scales of most species of Eucharis

and Caliphruria are apically articulated into a
neck or pseudostem of variable length. Distally,
the pseudostem grades into the petiole of individual
leaves. The neck of Eucharis and Caliphruria
bulbs always remains below the soil surface. Length
of the neck may therefore be more a factor of bulb
depth in the substrate rather than of any phylo-
genetic pd Bulbs of most species of Eu-
charis Caliphruria offset regularly and vig-

LEAVES
Leaves of Eucharis and Caliphruria are uni-
formly long-petiolate, with a well-developed elliptic,
ovate, or lanceolate lamina. Petiolate leaves are
characteristic of a number of genera of Amaryl-
lidaceae, either completely or in part, and have
undoubtedly evolved independently several times
from the linear or lorate leaf morphology typical
of the family.
The petiole of the leaf of Eucharis and Cali-
phruria is usually as long or longer than the lamina.
140
Annals of the
Missouri Botanical Garden
It tends toward subterete cross sections (Fig. 1),
rounded abaxially, and flattened adaxially, becom-
ing slightly channeled proximal to the sinus. The
petiole is winged proximal to the sinus by atten-
uation of the lamina. The midrib is pronounced
abaxially along the entire length of the lamina, and
slightly channeled adaxially, continuous with the
petiole.
Leaf shape only rarely provides taxonomically
useful information. Length / width ratios are subject
to considerable variation even among the leaves of
a single bulb. Herbarium specimens will frequently
include only a single leaf, with no indication of its
developmental age. Taxonomic consistency of leaf
shape is exceptional, but useful in the few cases
where it occurs. For example, leaves of E. ulei
Kranzlin are consistently narrowly elliptic. Eucha-
ris amazonica (leaf length / width ratio greater than
2) may be delimited from E. moorei (Baker) Mee-
row (1/w less than 2).
The leaves of Eucharis and Caliphruria are
completely glabrous and nonglaucous, with a single
exception. Eucharis bonplandii (Kunth) Traub, a
rare tetraploid species from central Colombia, de-
velops a glaucous bloom that gives the leaf a blue
cast in strong light.
The leaf apex of all species is shortly acuminate,
the base attenuate. Coarse undulation of the margin
will sometimes make the lamina appear cordate at
the base. Leaf margins of Caliphruria are uni-
formly nonundulate.
Leaf venation of Eucharis and Caliphruria is
parallelodromous (Hickey, 1973), with a great
number of transverse, commissural veins intercon-
necting the primary vasculature. All species of
Caliphruria have smooth, nonplicate leaves. Eu-
charis is variable for this character, but the ma-
jority of species have plicate leaves.
The adaxial epidermis of most species of both
genera is lustrous, dark green; the abaxial surface
appears lighter, or silvery green. Only E. astro-
phiala (Ravenna) Ravenna has diverged markedly
from the typical morphology and has a uniquely
nonlustrous, bullate-pustulate leaf texture.
CUTICLE
Cuticular striation is prominent on the abaxial
leaf surfaces of most Eucharis and Caliphruria
species (Figs. 2-6, 8-12). Striae are thickest in
C. subedentata (Fig. 11). Arroyo & Cutler (1984)
recognized eight cuticular sculpturing classes in a
survey of 25 genera of Amaryllidaceae. The most
common cuticular morphology of Kucharis and
Caliphruria fits their class VII: "thick striae, par-
allel or not, interlocking, + transverse.'
In a few species of Eucharis (E. amazonica,
E. moorei (Fig. 10), E. bouchei (Fig. 9)), the
striation is much less pronounced. Caliphruria kor-
sakoffii (Traub) Meerow (the sole representative
of Caliphruria outside Colombia) has the most
aberrant cuticle morphology (Fig. 12), correspond-
ing more or less to type V of Arroyo & Cutler
(1984): *central, thick axial striation with less pro-
nounced striae running from it, directly to anticlinal
walls." The adaxial cuticles of Eucharis and Cal-
iphruria are either smooth or rarely much more
finely striate than the abaxial surface, the striations
entirely axial in orientation. The adaxial cuticle of
C. korsakoffii (Fig. 13) has several, thick, trans-
verse striations across each cell, and the epidermis
is unusually flat.
STOMATA
Leaves of Eucharis and Caliphruria are pre-
dominantly hypostomatic. Stomata occur adaxially
only along the midrib and vicinity (Fig. 14A), and
occasionally in the proximity of primary veins.
Stomata are usually absent from the abaxial midrib
(Fig. 14B). Intercalary stomata were regularly ob-
served only in E. cyaneosperma Meerow (Figs. 7,
15D). The stomata of Eucharis and Caliphruria
are anomocytic, as is typical for Amaryllidaceae
(Arroyo & Cutler, 1984; Dahlgren & Clifford,
1982), though E. astrophiala exhibits at least
slight differentiation of cells neighboring the sto-
mata (Figs. 2, 3) from other epidermal cells. These
cells are more densely and regularly striate than
other epidermal cells, as well as slightly more raised.
The guard cells of Fucharis and Caliphruria are
oriented with their longest axis parallel to that of
the leaf.
EPIDERMAL CELLS
Abaxial epidermal cells range from rectangular
to irregular in shape. Adaxial epidermal cells are
in almost all cases rectangular. Kucharis astro-
phiala (Fig. 15A) has the most irregularly shaped
cells of both the abaxial and adaxial surfaces. In
the vicinity of the midrib on both surfaces of the
leaf (Fig. 14), epidermal cells become conspicu-
ously elongated, and anticlinal walls are straight.
Epidermal cells of the midrib are extremely long
and narrow.
The epidermal cells of all species of Eucharis
subg. Eucharis have strongly undulate anticlinal
walls (Fig. 15), as noted by Asatrian (1984) for
the few species he surveyed. End walls of both the
abaxial and adaxial cells of all species range from
oblique to rounded. Abaxial cells are more strongly

undulate than those of the adaxial surface. Epidermal
cells of Caliphruria (Fig. 15F) are more weakly
undulate than those of Eucharis. The anticlinal
walls of adaxial cells of C. korsakoffii are com-
pletely straight. Eucharis subg. Heterocharis is
polymorphic for anticlinal wall morphology. Ku-
charis amazonica and E. sanderi have strongly
undulate walls, while E. moorei (Fig. 15E) has
essentially straight walls.
LEAF ANATOMY
In petiolar transverse section, a single arc of
vascular bundles is usually observed (Fig. 1). Me-
dian bundles are the largest. In petioles of E. moorei
(Fig. 1E) and the closely related E. amazonica
(Fig. 1F), both in subg. Heterocharis, small sec-
ondary bundles were observed near the adaxial
surface. These bundles are most conspicuous in £F.
moorei; they are markedly smaller in E. amazon-
ica. These secondary vascular traces disappear
above the middle of the petiole. Asatrian (1984),
who reported on petiole anatomy of three Eucharis
and Caliphruria species, did not observe these
bundles in E. amazonica (cited as E. grandiflora).
The internal morphology of leaves of Eucharis
and Caliphruria (Figs. 16-22) is largely invariant
across both genera. No well-defined palisade layer
is evident, the absence of which is characteristic
of most genera of "infrafamily" Pancratioidinae
(Arroyo & Cutler, 1984). Mucilage cells, common
throughout the family (Arroyo & Cutler, 1984),
are often present near the leaf surface, and ra-
phides are occasionally observed in epidermal cells.
The mesophyll consists of several layers of chlo-
renchyma both ad- and abaxially, and a thicker
region of spongy, slightly aerenchymous tissue.
Small air cavities occur regularly only directly be-
low stomata. Vascular bundles are surrounded by
a sheath of one or two layer(s) of parenchymous
cells. The only xylem elements present are tra-
cheids with annular thickenings (Fig. 19).
FLORAL MoRPHOLOGY
INFLORESCENCE
The inflorescence of Eucharis and Caliphruria
is a naked scape typical of Amaryllidaceae. The
scape is subterete in cross section and has a solid
pith. Vascular bundles are distributed in several
irregular, concentric rings within the pith. A layer
of collenchyma cells occurs just below the epider-
mis.
The scape is terminated by two valvate-imbri-
cate, ovate-lanceolate bracts that enclose several

secondary bracts and the flower buds before an-
thesis. These bracts vary from green (E. subg.
Heterocharis) to greenish white (most species of
subg. Eucharis) and are soon marcescent after
opening and spreading laterally. Each flower is
subtended by a linear-lanceolate bracteole.
The inflorescence of the Amaryllidaceae is tra-
ditionally described as **umbellate." Mann (1959)
and Stout (1944) demonstrated that the superfi-
cially simple umbel of Amaryllidaceae actually rep-
resents a complex series of reduced, helicoid cymes.
Anthesis occurs in a strict sequence within each
cyme from the developmentally oldest flower to the
youngest. The peripheral cymes flower first; the
central cymes flower last.
Flower number varies in Eucharis and Cali-
phruria from 2 to 10, rarely as many as 12 (C.
korsakoffii, rarely in E. castelnaeana). Number
of flowers is often a taxonomically useful character,
though any species characterized by 8-10 flowers
is capable of producing a depauperate inflorescence
with fewer florets. An increase in flower number

generally does not occur. In some species of subg.
Eucharis (E. astrophiala, E. bouchei, E. ulei), a
flower number of five has become virtually fixed.
Reduction in flower number is usually considered
the derived state in Amaryllidaceae (Traub, 1962,
1963).
FLOWER SIZE
The largest flowers in Eucharis are found in
subg. Heterocharis, where they average 7-8 cm
in length. Flowers of Caliphruria are the smallest,
never exceeding 4 cm long. Subgenus Eucharis,
the largest of the two subgenera of Eucharis, is

variable, with flowers 3-7 cm in length. Within a
fairly broad range, flower size can be used to dis-
tinguish phenetic species complexes within subg.
Eucharis; however, most species of this subgenus
are quite variable in size (Meerow, 1987 d, in press).
FLORAL FRAGRANCE
Subgenus Heterocharis is the only subgenus of
Eucharis with uniformly fragrant flowers. The fra-
grance of all species of subg. Heterocharis is in-
tense and sweet. Flowers of Caliphruria do not
emit any detectable fragrance. Most species of
Eucharis subg. Eucharis also lack noticeable fra-

(E. bakeriana N. E. Brown, E. castelnaeana (Bail-
lon) Macbr., E. formosa Meerow, and E. plicata
Meerow subsp. brevidentata Meerow), the odor is
not intense. In £. formosa the odor is slightly fetid.
PERIANTH
The perianth of Eucharis and Caliphruria con-
sists of six tepals in two whorls, basally connate
into a tube of varying length and morphology. The
tube of Eucharis subg. Eucharis (Fig. 23E) is
cylindrical for almost its entire length, abruptly
dilating near the perianth throat. The tube of subg.
Eucharis is also strongly curved, either abruptly
just above the ovary (E. bakeriana, E. cyaneo-
sperma) or gradually throughout the proximal half
of its length (all other species). The curving of the
tube results in the pendent habit of most species
of subg. Eucharis. The tube is white for its entire
length.
The tube of subg. Heterocharis (Fig. 23C, D)
is tinted green proximally (for as much as half its
length). The tube is curved, though not as markedly

Heterocharis (Fig. 23C, D).
The tube of Caliphruria (Fig. 23A) is straight
and dilates gradually from base to throat. It is either
subcylindrical (C. korsakoffii) or funnelform (all
other species). The tube is tinted green proximally
(in C. subedentata, for V$—75 of its length).
The tepals of Eucharis and Caliphruria flowers
are white. Those of the outer series are almost
always longer and narrower than the inner tepals.
The outer tepals are apiculate. The apiculum fre-
quently has a small, papillate horn on the adaxial
surface in Eucharis subg. Eucharis. The inner
tepals vary from acute to obtuse, sometimes mi-
nutely apiculate, at the apex.
e tepals of most species of subg. Eucharis
spread at an angle of 90? or more from the throat.
Perianth morphology of subg. Eucharis is thus
predominantly crateriform. At times the tepals may
be reflexed strongly above the midpoint of their
length, or rarely for their entire length. Tepal habit
varies even among flowers of the same inflores-
cence and shows no taxonomic consistency. If ex-
posed to strong light, the abaxial midrib of the
tepals of some species of subg. Eucharis may be
lightly pigmented yellow.
The perianth of Caliphruria is infundibular. The
tepals remain imbricate for half their length and
spread distally at angles of only 45-60”. The tepals
of subg. Heterocharis are also for the most part
imbricate proximally and spread at 45-60? from
the throat. The perianth is more or less campan-

ANDROECIUM
The stamens of Eucharis and Caliphruria are
variously connate proximally. In all but three species
of Eucharis, a conspicuous staminal cup is present
(Figs. 24, 25). In Caliphruria, the cup is reduced
to a short, membranous, connate portion of the
filaments near the perianth throat (Fig. 26). Fu-
charis sanderi (subg. Heterocharis) has a reduced
staminal cup similar to that of Caliphruria. Stam-
inal connation is one of the major characteristics
of *'infrafamily"
workers considered the staminal cup of pancratioid
genera homologous to the corona of Narcissus L.
(e.g., Pax, 1888). The corona of Narcissus is
generally considered to be of perianthal origin
(Eichler, 1875; Arber, 1937), while the staminal
cup of pancratioid taxa has been described as com-
posed entirely of androecial tissue (Arber, 1937;
Singh, 1972). Einsiedel (1987) and Müller-Doblies
(pers. comm.) consider this distinction artificial and
claim that both structures arise from the same
meristematic potential, citing putative instances of
polymorphy for both types within the same genus.
Stamens of Eucharis and Caliphruria may be
dentate, edentate, or irregularly toothed. Both types
of staminal morphology may occur in the same
species, and variation may occur even among flow-
Pancratioidinae. Some taxonomic

Caliphruria are completely white. In subg. Het-
erocharis, the green (rarely yellowish) pigmenta-
tion is largely restricted to the interior of the cup,
and extends into the dilated portion of the tube as
well (Fig. 25). The coloration is concentrated along
the filamental traces, but the tissue between the
traces is also suffused with green. In subg. Kucha-
ris, pigmentation is present on both the exterior
and interior surfaces of the cup, does not extend
into the dilated portion of the tube, and takes the
form of either broad spots below each free filament
or a uniform band of color at the basal V$- V4 of
the cup. In this subgenus, the pattern is of limited
taxonomic significance. Whether the pigmentation
functions as nectar guides for pollinating animals
is unknown.
The stamens of most species of subg. Eucharis
constrict distally into a broadly subulate portion
(greater than 1 mm wide for most of its length) of
varying length. Only in E. astrophiala (Fig. 24)
and E. bouchei (in part) do the stamens constrict
gradually from the rim of the staminal cup to the
apex of the filament. The free filaments of Cali-
phruria are narrowly subulate (less than 1 mm
wide for most of their length, Fig. 26). The free
filaments of E. sanderi (subg. Heterocharis) are
narrowly subulate and slightly incurved. Those of
E. moorei and E. amazonica are broadly subulate.
Anthers of Eucharis are introrse, dehiscing lon-
gitudinally, and either dorsifixed or sub-basifixed.
They are most frequently oblong but are linear in
subg. Heterocharis. At anthesis, the anthers of
Caliphruria and Eucharis subg. Eucharis are erect
but become versatile as they age. In subg. Het-
erocharis, the anthers are versatile at anthesis.
STIGMA AND STYLE
Of the sixteen species of Kucharis and Cali-
phruria observed in cultivation, all but Æ. castel-
naeana are protandrous. Stigma receptivity does
not occur until the second or third day following
anther dehiscence. In some cases, the stigma does
not fully expand until the perianth has begun to
senesce. Successful greenhouse pollinations have
been accomplished after the onset of periant
nescence. In the single known autogamous species,
E. castelnaeana, stigma receptivity and anther
dehiscence coincide

Eucharis and Caliphruria
The stigmatic papillae of Eucharis are unicel-
lular (Figs. 28, 34-37), while those of Caliphruria
(Fig. 31) are multicellular, consisting of both a
stalk cell and globose head cell. x Calicharis
butcheri, putatively a natural hybrid of E. sanderi
and C. subedentata, has the multicellular stigmatic
papillae (Figs. 38, 39) characteristic of Caliphru-
ria. Heslop-Harrison & Shivanna (1977) charac-
terized the stigmas of Eucharis and Caliphruria
as dry-type.
OVARY AND OVULES
The ovary of Eucharis and Caliphruria is in-
ferior and contains septal nectaries. It is green,
with the exception of two species, E. astrophiala
and E. castelnaeana (subg. Eucharis), in which
the ovary is white at anthesis. Ovaries of Eucharis
and Caliphruria range from oblong-ellipsoid (subg.
Heterocharis) to globose or subglobose (Caliphru-
ria and Eucharis subg. Eucharis). The ovary of
subg. Heterocharis appears rostellate after senes-
cence of the perianth.
The ovules of Eucharis and Caliphruria are
globose, anatropous, and borne on axile placentae.
Ovule number is quite variable throughout both
genera. Within limits, however, this number is
characteristic of species or species complexes. Sub-
genus Heterocharis has the largest ovule number
in Eucharis, generally 16-20 per locule, but oc-
casionally as low as 7 in E. sanderi (which oth-
erwise has 16-20 throughout most of its range)
and 9-12 in E. amazonica. In both Caliphruria
and Eucharis subg. Eucharis, ovules do not num-
ber more than ten per locule. Eucharis astrophi-
ala, E. bouchei, E. bonplandii, E. cyaneosperma,
and E. ulei characteristically have two ovules per
locule, but rarely as many as five.
FRUIT
The mature fruit of Eucharis and Caliphruria
is a triloculicidal capsule typical of the nonbaccate-
fruited Amaryllidaceae. In fruit, the pedicel elon-
gates to two or more times its length at anthesis.
In Caliphruria and Eucharis subg. Heterocharis
(E. moorei), the capsule is thin-walled and green,
sometimes turning yellow or brown at dehiscence.
In subg. Eucharis, however, the capsule is leathery
and bright orange (Fig. 40), contrasting vividly
with the shiny black or blue seeds at dehiscence.
It is probable, though unsubstantiated, that the
combination of fruit and seed color functions mi-
metically to attract avian dispersal agents (sensu
van der Pijl, 1982). In the single known exception
to this characteristic fruit morphology in subg.
Eucharis, the fruit of E. castelnaeana (Fig. 41)
remains green until shortly before dehiscence, at
which time it yellows and finally turns brown. It is
often tardily dehiscent and sometimes abscises be-
fore opening, though the seeds within are ripe.
SEED
Regardless of the number of ovules per locule
in any species of Eucharis and Caliphruria, all
but a few abort as the fruit matures. Generally one
to three seeds are present per locule in mature
capsules, but as many as four have been observed
(Fig. 40)
The seeds of both Eucharis and Caliphruria
are globose or ellipsoid and turgid, the consequence
of copious, oily endosperm and a high moisture
content. Left at room temperature, the seeds will
shrink away from the testa somewhat as moisture
is lost but remain capable of germination. Long-
term viability has not been tested.
The seed of subg. Eucharis (Fig. 42) is char-
acteristically ellipsoid and has a shiny, smooth black
(blue in E. cyaneosperma) testa. The single ex-
ception so far known is again E. castelnaeana (Fig.
43). The seed of this species is wedge-shaped by
compression in the capsule, is less turgid than seeds
of consubgeneric species, and has a dull, rugose
testa. The seed of E. moorei (subg. Heterocharis)
is globose to very slightly compressed and has a
brown, slightly rugose testa.
In Caliphruria, the seeds of only C. korsakoffi
and C. subedentata are known. Seeds of C. kor-
sakoffii are globose, turgid, and have a smooth,
lustrous brown testa. Seed of C. subedentata is
slightly compressed, with a lustrous black but ru-
gose testa.
The testa is alveolate in all species examined
(Figs. 44-49). In E. bouchei var. dressleri Mee-
row (Fig. 45), abundant wax extrusions are found
Caliphruria seeds is composed of phytomelan
(Huber, 1969), a simple, largely inert, carbona-
ceous compound characteristically present in the
seed coat of nonbaccate-fruited Amaryllidaceae
(Dahlgren & Clifford, 1982; Huber, 1969). Wer-
ker & Fahn (1975) reported the occurrence of
phenolic quinones in the phytomelan layer of Pan-
cratium seeds. In most species of Eucharis and
Caliphruria, the phytomelan layer is all that re-
mains of the integuments (Figs. 51, 57). In £.
bouchei, however, there is an additional layer of
integument tissue about five cells thick, interposed
between the phytomelan and the endosperm (Fig.
55). Whether this may be a consequence of the

have fleshy, pora sometimes viviparous seeds,
but they are not The “ps

form propagules of Hymenocallis, while true seeds,
have thick, fleshy chlorenchymous integuments with
a well-developed vascular system and a starch-
storing embryo (Rendle, 1901; Whitehead &
Brown, 1940). These important seed differences
have been overlooked by most phylogenists of the
Amaryllidaceae.
The turgid seed of Kucharis and Caliphruria,
despite a high moisture content when first ripe,
cannot be accurately described as fleshy. This be-
comes evident if the seed is allowed to dehydrate
slightly at room temperature, and is most apparent
in the hard seeds of E. castelnaeana, which, at
capsule dehiscence, are less turgid than seeds of
other species of subg. Kucharis. Seeds of Eucharis
and Caliphruria have a reduced integument, rep-
resented in most cases only by the compressed
phytomelan layer, and have never been observed
to germinate viviparously. Phytomelan is absent
from the testa of the pseudoseeds of Kurycles and
Calostemma. It is present in only a single species
of Hymenocallis, H. quitoensis Herbert (and prob-
ably its close relative H. heliantha Ravenna), which
has been segregated into the separate genus Lep-
idochiton Sealy (1937) on this basis.
Seeds of Pancratium are structurally most sim-
ilar to those of Eucharis and Caliphruria. Al-
though variable in shape and surface features
(Werker & Fahn, 1975), all species of Pancratium
have a hard, turgid, ovoid or compressed seed body
with copious endosperm (Meerow, unpubl. data;
Werker & Fahn, 1975). All examined species of
Pancratium have a phytomelanous and alveolate
testa. Seeds of Eucharis and Caliphruria have a
higher moisture content than those of Pancratium,
all species of which occur in xeric to seasonally
dry habitats.
POLLEN MORPHOLOGY
Pollen morphology of Eucharis and Caliphruria
is reviewed in detail elsewhere (Meerow & Deghan,
1988) and will only be summarized here. Pollen
grains of all species of Eucharis and Caliphruria
(Figs. 59-62) are boat-shaped elliptic, monosul-
cate, heteropolar, and bilaterally symmetrical. The
sulcus runs the length of the distal face of the
grain. Exine sculpturing is semitectate/reticulate
in all species examined.
Pollen of most Eucharis falls into Walker &
Doyle's (1975) large size class (longest equatorial
diameter 50-100 um). A single species, E. cau-
cana, has very large pollen (longest equatorial di-
ameter as much as 110 um). Pollen of Eucharis
has average longest equatorial diameters greater
than 60 um, with two exceptions: E. castelnaeana
and E. plicata subsp. brevidentata, the two small-
est-flowered species. Most species of Eucharis have
pollen grains with longest equatorial diameters be-
teen 65 and 75 um. Pollen of Caliphruria falls
into the medium size class of Walker & Doyle
(1975), with average longest equatorial diameters
near 50 um. Polar diameter of pollen of most
Eucharis species ranges from 45 to 60.6 um—
diameters less than 40 um are rare. Polar diameter
of pollen of Caliphruria is always less than 40
um. Exine reticulation of Eucharis is character-
istically coarse (Figs. 59-61), while that of Cali-
phruria is fine (Fig. 62).
CHROMOSOME CYTOLOGY
A somatic chromosome number of 2n = 46
largely characterizes both genera (Meerow, 1987b).
Two tetraploid species (2n = 92), E. bonplandii
from Colombia and E. bouchei from Central Amer-
ica, are known. Eucharis caucana, described in
this paper from Colombia, is a hexaploid with the
largest chromosome number in the genus (2n —
138). Eucharis amazonica, 2n — 68, is the only
known departure from these 2x, 4x, or 6x karyo-
types. À somatic chromosome number of 2n — 46
(or derivations thereof) is characteristic of most
genera of neotropical Pancratioidinae (Di Fulvio,
1973; Flory, 1977; Meerow, 1987b, c; Williams,
1981).
EcoLoGY AND PHYTOGEOGRAPHY
ECOLOGY
All species of Eucharis and Caliphruria exhibit
high fidelity to a primary forest habitat, and severe
disturbance of the forest canopy is catastrophic to
the plants. In recently cleared forest sites, the bulbs
persist for a few seasons, but the leaves developed
in sunlight show chlorosis and necrosis. Wilkins
(pers. comm.) reported that leaves of E. amazonica
are damaged at light levels above 5,000 foot can-
dles, an observation confirmed by Rees (1985).
Fidelity of these genera to mesic, low-light habitats
suggests a strongly evolved adaptive complex. Only
two other genera of pancratioid Amaryllid are
completely adapted to forest understory: Eurycles,
a small Australasian genus, and Urceolina, sister
group to Eucharis and Caliphruria.
Eucharis populations are often largest on flood-
plains of small rivers and creeks where frequent
short-term inundation is likely. Eucharis is also
found in more upland sites, but usually in less
abundance. No fully deciduous species of subg.

Eucharis have been observed, though E. astro-
phiala, endemic to the western slopes of north-
central Ecuador, enters a season of dormancy when
growth ceases. Yet several leaves may persist for
the duration.
The rarity of Eucharis and Caliphruria species
throughout their range is a striking characteristic
of their distribution. Single, widely dispersed clumps
of bulbs are more the rule than the exception.
Herbarium collections are usually unicates and often
indicate the relative infrequency with which the
plants were encountered in the forest. The largest
population of Eucharis that I have observed con-
sisted of about 30 individuals of E. moorei in an
approximate half-hectare area. Throughout eastern
Ecuador, populations of only two or three clonal
clumps or single bulbs (and frequently as low as
one) of E. candida, E. formosa, and E. moorei
are common. In eastern Peru, a careful search
through a five-hectare area turned up only two
plants of E. cyaneosperma. Edaphic conditions are
probably important in limiting colonization and es-
tablishment of Eucharis species. Restriction to sites
of high fertility is evident for all species of Eucharis
and has been noted by floristic workers in the
Amazon basin and Chocó region of Colombia (A.
Gentry, pers. comm.).
No species of Eucharis are found natively above
1,800 m. The overwhelming majority of collections
are from elevations below 1,000 m and, of these,
more than half are below 500 m. Caliphruria is
primarily collected at sites above 1,000 m (“selva-
subandina" of Cuatrecasas, 1958). Most collec-
tions of Caliphruria (C. subedentata) were from
the Río Cauca River valley of western Colombia,
an area now largely deforested. In July 1984, 1
was not able to find members of this genus in any
of its historical localities.

PHYTOGEOGRAPH Y
More than half of the known species of Fucharis
subg. Eucharis are found on the eastern slopes of
the Andes. The majority of these species are con-
centrated along the Amazon and its main tributar-
ies, e.g., the Napo and Pastaza system in Ecuador
and the Huallaga of Peru. Seven of the fourteen
extant species of subg. Eucharis are endemic to
the premontane Andean- Amazonas interface, but
no species has been reported east of 68°W longi-
tude. Thus the genus appears to be absent from
the great, largely Brazilian expanse of lowland
Amazonas. Five peripheral isolate species from the
premontane Andean-Amazonian center of distri-
bution show some degree of morphological novelty
(see Taxonomic Treatment). Eucharis corynan-
dra, very closely related to E. castelnaeana and
E. plicata, and E. oxyandra, of uncertain phy-
logenetic relationship, are both known only from
the “ceja de la selva” forest formations of north-
central eastern Peru. Eucharis astrophiala is en-
demic to a relatively small area of western Ecuador.
Eucharis lehmannii and E. caucana are restricted
to western Columbia. Of the five species, only £.
astrophiala is known from other than the type
locality.
Three of the four species of subg. Eucharis that
occur above 2°N latitude are polyploids (chromo-
some number is unknown for E. lehmannii). Eu-
charis bonplandii (2n — 92), endemic to the Cor-
illera Oriental and Cordillera Central of Colombia
is rare and infrequently collected. The E. bouchei
complex (2n — 92), a series of geographically isolat-
ed and morphologically distinct population clusters
(Meerow, 1987d), is endemic to Central America,
chiefly Panama. Eucharis caucana is a hexaploid
(2n = 138)
Subgenus Heterocharis is widely dispersed from
Colombia to Peru, but each of its three species are
arrowly distributed. With the exception of a single
E. moorei is not
Eucharis found on both sides of the Andes. Eu-
charis amazonica occurs natively within a narrow
area of the Rio Huallaga valley in Peru. Eucharis
sanderi is endemic to the Chocó region of Colom-
ia.
Caliphruria is almost completely western Co-
lombian, most prominently in the Rio Cauca valley,
with a secondary distribution in the Río Magdalena
valley. Caliphruria korsakoffii is Peruvian.
ETHNOBOTANY
Labels of a number of herbarium specimens of
Eucharis species indicate that lowland native peo-
ple collect the bulbs for use as poultices. The bulbs
are mashed, heated, and applied to sores and tu-
mors. Lewis (1986) described the use of mucilage
from Eucharis bulbs (the plant illustrated is Æ.
formosa) by the Jivaro Indians of Peru for treating
facial blemishes and acne. Indian women of the
Pastaza valley in Ecuador reportedly quite actively
collect the plants in flower for reasons they would
not disclose (N. Whitten, pers. comm.). Most local
inhabitants whom I met while collecting Eucharis
in the Oriente were readily familiar with the plants
when shown photographs.
That various neotropical Amaryllidaceae have
been cultivated in their native countries for many
years cannot be discounted. Motifs recognizable as
species of Zephryanthes Herbert and Stenomes-
son Herbert appear on ceremonial Incan vases
(Vargas, 1981). The seasonal mass-blooming of
Hymenocallis amancaes (Ruiz & Pavón) Nichols.
on the dry hills near Lima, Peru, has long been
the nucleus of an annual festival named for that
species (Herbert, 1839). I have suggested that
frequent sympatric occurrence of E. candida and
; y have been
influenced by cultivation by transient agriculturists
(Meerow, 1987e). Further circumstantial evidence
for this hypothesis is the doen in nature E
sterile hybrid taxa such as F. randiflora a
X Calicharis butcheri. Almost all collections of i
former are remnants of cultivation. Eucharis ox-
yandra is known only from bulbs found uprooted
by an abandoned dwelling in Peruvian rain forest
(see Taxonomic Treatment).
E. formosa in eastern Ecuador ma
REPRODUCTIVE BIOLOGY
PHENOLOGY
Eucharis and Caliphruria species are largely
seasonal flowering. Very well-collected species, such
as E. candida or E. formosa, show flowering pat-
terns skewed toward certain months (January to
arch), but at least several flowering collections
have been made throughout the year. Species in
Amazonian Peru have been collected in flower most
frequently from June to September. Each inflores-
cence is moderately long-lived, two to three weeks,
but usually no more than one to three flowers are
open at any one time
In the greenhouse, observations over a five-year
period confirm an annual flowering for most Eu-
charis and Caliphruria species. Eucharis ama-
zonica, however, flowers two or three times during
the year. Van Bragt & Sprenkels (1983) have
regularly induced flowering in this species at any
time of the year after treatment at 27?C for at
least two weeks. Collection data for this species
Volume 76, Number 1
1989
Meerow 157
Eucharis and Caliphruria
throughout its narrow range indicate that twice-
annual phenology may occur in habitat as well.
Eucharis castelnaeana mass-flowers in the green-
house several times per year. Other well-collected
species (e.g., E. candida and E. formosa) that
show a peak period of flowering in certain months
in nature are strictly annual-flowering in cultiva-
tion.
POLLINATION BIOLOGY
Data on pollination ecology of Amaryllidaceae
in general are scant and represent an area sorely
in need of investigation. No information on polli-
nation of Caliphruria is available. The large, white,
heavily and sweetly fragrant flower of E. amazon-
ica (subg. Heterocharis) was considered a model
moth-pollinated flower by Percival (1965). She not-
ed that the nectar level in the tube rises to a
maximum height of 2376 tube length, thus effec-
tively preventing access to all but long-tongued
insects. The large, heavily fragrant flowers of subg.
Heterocharis fit the syndrome of sphingid moth
pollination (sensu Faegri & van der Pijl, 1979).
Other related genera of *'infrafamily" Pancratioi-
dinae with similar flower morphology are special-
ized for hawkmoth pollination (Hymenocallis:
Bauml, 1979; Grant, 1983; Pancratium: Morton,
1965).
Floral fragrance is rare in subg. Eucharis, oc-
curring in only E. bakeriana, E. castelnaeana, E.
formosa, and E. plicata subsp. brevidentata.
However, floral fragrance is only weakly developed
these species, and in E. formosa the odor is
slightly fetid. Vogel (1963) reported euglossine bees
visiting Eucharis bakeriana. Visitation by an un-
identified euglossine has been reported for other,
unidentified species of subg. Eucharis in Peru (J.
Schunke, pers. comm.). Unfortunately, neither re-
port indicated the sex of the visitor. The phenology
of Eucharis (rarely more than one or two flowers
open per inflorescence at any one time over à
period of two or three weeks, and the often suc-
cessive appearance of inflorescences from a clonal
clump of bulbs) and the dispersed distribution of
plants in the wild suggests pollination by a trap-
lining organism (see Janzen, 1971)
DISPERSAL
The leathery, bright orange fruit of Fucharis
subg. Eucharis is a major apomorphy that defines
the subgenus. At dehiscence, the contrast between
the capsule and the lustrous black or blue seeds
creates a striking visual display in the forest under-
story, but there are no recorded observations of
visitation to the ripe capsules.
BREEDING SYSTEM
On the basis of greenhouse pollination attempts,
virtually all species of Eucharis and Caliphruria
demonstrate some degree of self-incompatibility.
This observation suggests that most species are
predominantly outcrossing. Capsules have been set
readily with sibling pollen on all species in culti-
vation with the exception of E. amazonica and
functionally sterile hybrid taxa (E. x grandiflora,
x Calicharis butcheri). Further evidence of out-
crossing is the marked protandry of most Eucharis
species (with the exception of E. castelnaeana, in
which stigma receptivity coincides with anthesis)
and the presence of putative interspecific hybrids
in nature (E. candida x E. formosa (Meerow,
1988), E. plicata subsp. plicata x E. ulei (Mee-
row, in prep.)). Of all species in cultivation, only
7. castelnaeana sets capsules with self-pollen.
Autogamy in E. castelnaeana is associated with a
number of other divergent character states for
subg. Eucharis. This species has a mass-flowering
phenology; the smallest flowers in the genus; a
green, often tardily dehiscent capsule; a less turgid
seed with a dull, rugose testa; and telocentric chro-
mosomes.
Reproductive biology of Eucharis and Cali-
phruria is thus still largely conjectural. Annual
flowering patterns, short-term pollen viability, and
susceptibility to systemic diseases in cultivation
impede greenhouse exploration of these questions,
and the rarity of the plants is an obstacle to field
studies. The disappearance of populations of these
genera and their pollinating agents, concurrent with
ain forest destruction, may be the final impediment
to investigation of this aspect of their biology.

PHYLOGENETIC RELATIONSHIPS
Eucharis and Caliphruria have been variously
treated as separate genera (Baker, 1888; Bentham
& Hooker, 1883; Pax, 1888; Hutchinson, 1959),
a single genus (Traub, 1963), and as subgenera of
Urceolina (Traub, 1971). As a group, Eucharis,
Caliphruria, and Urceolina appear to represent
a distinct tribal assemblage within “‘infrafamily”
Pancratioidinae Traub (1957, 1963), a group de-
limited by various patterns of staminal connation,
somatic chromosome number frequently of 2n —
46, and an Andean center of diversity (Meerow,
1985, 1986, 1987a, c).
PHYLOGENETIC ANALYSIS
Despite a lack of consensus on generic and spe-
cific limits in Amaryllidaceae, cladistic analysis has
only twice before been applied to such problems

related, baccate-fruited African genera; and Mee-
row (1987c) for Eucrosia Ker Gawler. The generic
limits of Eucharis and Caliphruria in relation to
Urceolina, as well as interspecific relationships in
the former genera, seemed two areas that would
two closely
benefit from the application of cladistic analysis.
Before assessing these relationships cladistically, a
brief review of character states in Urceolina is
necessary.
Urceolina (ca. 6-8 species; Fig. 63) is so far
known only from central and southern Peru on the
eastern Andean slopes (Fig. 64) at elevations of
700-2,000 m. The relationships of Urceolina have
long been misunderstood, most workers (Baker,
1888; Pax, 1888; Hutchinson, 1959) placing Ur-
ceolina near Stenomesson Herbert. Traub (1957)
was the first to recognize its affinities with Eucharis.
The problem no doubt stemmed from the inclusion
of a species of Stenomesson (S. miniatum (Her-
bert) Ravenna) in Urceolina as U. miniata (Her-
bert) Benth. & Hook. Despite the ventricose aspect
of the corolla morphology of 5. miniatum, which
is similar to that of Urceolina, the species clearly
belongs to Stenomesson as evidenced by its narrow,
subpetiolate leaves, the morphology of its staminal
cup, and its numerous flat, black seeds (Ravenna,
Urceolina is easily distinguished by its brightly
colored, urceolate corolla formed by the coherence
of the tepals throughout most of their length (Fig.
63A). Vargas (1960) described the genus Pseu-
dourceolina to accommodate a species of Urceo-
lina in which the tepals are supposedly more laxly
coherent. The morphology of the flower in Urceo-
lina strongly suggests ornithophily (sensu Faegri
& van der Pijl, 1979), i.e., vivid, "parrot" colors,
ventricose corolla, pendulous habit, and absence
of odor. As in Caliphruria, the staminal cup of
Urceolina is reduced to a minute, membranous,
basal connation of the filaments, which are oth-
erwise linear throughout their length. The leaves
of Urceolina, in thickness and lack of both surface
plication and marginal undulation, resemble Cali-
phruria more closely than Eucharis. At least one
species is hysteranthous (U. microcrater Kranzlin),
but all species enter a leafless dormant period in
the wild. In size the pollen grains of Urceolina (Fig.
63E) are similar to those of Caliphruria. The
coarseness of the reticulum is intermediate between
that of Eucharis and Caliphruria. In all species
of Urceolina the small stigma is capitate and entire
(Fig. 63G) versus the trilobed stigma found in Eu-
charis and Caliphruria. Urceolina species have
10-20 ovules. The ripe fruit of Urceolina is a thin-
walled, yellow-green, turbinate capsule. The seeds
of U. microcrater (Fig. 63H) are narrowly oblong,
ca. 8 mm long, and 2.5 mm wide, and curved.
The seeds have a unique anatomical feature: at
the chalazal end, a dam of poorly differentiated
tissue separates a "cap" composed of many small
cells from the endosperm (Fig. 63J, L). The cells
of the “cap” do not have pitted walls with plas-
modesmata as is characteristic of the endosperm
cells. There is no obvious surface feature on the
seed corresponding to the area of this "cap," and
its function is unknown.
Outgroup selection. Preliminary cladistic
analyses of the pancratioid Amaryllidaceae (Mee-
row, 1985) indicate that within the Pancratioidi-
nae, a large, white, fragrant, crateriform flower
with a conspicuous staminal cup (““paneratioid,”
cf. Pancratium L.), involved with sphingid moth
pollination (Bauml, 1979; Grant, 1983; Morton,
1965), may be symplesiomorphous. In other words,
while the pancratioid flower was a major apomor-
phy defining the Pancratioidinae as a distinct group
within the Amaryllidaceae, it is the ancestral floral
morphology from which all other pancratioid taxa
have diverged. I have used the term “the pancra-
tioid base"
tioidinae with this type of flower morphology (Mee-
5). These five genera are Eucharis,
Hymenocallis, Pancratium, Pamianthe Stapf, and
Paramongaia Velarde. All but Pancratium are
entirely neotropical in distribution. The pancratioid
to define the five genera of Pancra-
row,
flower correlates repeatedly with the largest pollen
grain size within the Pancratioidinae (Meerow,
1985; Meerow € Dehgan, 1985). Putatively basal
complexes within each pancratioid lineage also have
numerous ovules per locule (ca. 20 or more), a
character state considered primitive in the Ama-
ryllidaceae (Traub, 1963).
Pollen morphology provides the best evidence
for the monophyly of the Pancratioidinae. The
large pollen grains of most species of the pancra-
tioid base are uniformly coarsely reticulate, with
some in each genus exhibiting a striking exine

(Meerow, 1985; Meerow & Dehgan, 1985). None-
theless, separate origins of the pancratioid flower
in the Neo- and Paleotropics cannot be ruled out.
That the neotropical tribes of the Pancratioidi-
nae represent a monophyletic group is a much more
robust hypothesis. All neotropical pancratioid gen-
era have 2n = 46 as the most common somatic
chromosome number (Di Fulvio, 1973; Flory, 1977;
Meerow, 1985, 1987a, c; Williams, 1981). This
number may be derived from 2n = 22, the most
tic cl ber in the family

(Flory, 1977; Goldblatt, 1976; Meerow, 1984) via
duplication or fragmentation of a chromosome, fol-
lowed by doubling of the genome (Lakshmi, 1978;
Sato, 1938). All paleotropical pancratioid genera
have 22 or 20 chromosomes (Ponnamma, 1978;
Zaman & Chakraborty, 1974).
Pancratium (ca. 17 species) and two species of
Hymenocallis (H. quitoensis Herbert and H. he-
liantha Ravenna) were used as the primary out-
groups in the analyses presented. Character state
data on these taxa were accumulated from study
of living material, herbarium specimens and liter-
ature (Björnstad, 1973; Meerow & Dehgan, 1985;
Morton, 1965; Ponnamma, 1978; Ravenna, 1980;
Traub, 1962; Werker & Fahn, 1975). Pancra-
tium is putatively the least derived genus of the
pancratioid base (Meerow, 1985). It is the only
paleotropical genus of the group, and the o
member with 2n = 22 (Ponnamma, 1978), con-
sidered by most workers as the ancestral somatic
chromosome number in the family (Flory, 1977;
Goldblatt, 1976; Meerow, 1984).

species of Hymenocallis with phytomelanous seed
coats. All evidence suggests that possession of phy-
tomelan is the ancestral condition in the Amaryl-
lidaceae, and despite several independent losses,
no reversal to the ancestral state has been proposed
(Dahlgren & Clifford, 1982; Dahlgren & Ras-
mussen, 1983; Dahlgren et al, 1985; Huber,
1969). Hymenocallis quitoensis was segregate
into a separate genus, Lepidochiton Sealy (1937)
on the basis of phytomelanous seed. Both H. qui-
toensis and H. heliantha are ephemeral compo-
nents of the xeric flora of southwestern Ecuador
and northwestern Peru, and differ only in flower
color. Traub (1962) considered H. quitoensis a
relict and the most primitive species of Hymeno-
callis on the basis of ovule number (ca. 20 per
locule; 2-10 occurs in all other species) and chro-
mosome number (2n — 24, based on Snoad, 1952);
however, collections from Peru and Ecuador that
have examined have 2n — 34. These are the
lowest reported chromosome numbers in the genus
(Flory, 1976). These species will be called Lepi-
dochiton in the following discussion. Additional
analyses were run using other members of the
pancratioid base as outgroups (Hymenocallis subg.
Hymenocallis, H. subg. Ismene (Salisb.) Baker ex
Traub, Pamianthe, and Paramongaia). The re-
sulting cladograms were either equal in length or
slightly less parsimonious than those presented here;
they did not show changes in the resolution of
terminal taxa from the cladograms presented.
Ordered characters. Ten of the 18 multistate
characters (Table 2) used in these analyses (8, 9,
0, 13, 24, 25, 27, 28, 30, and 35) were ordered
into linear transformation series. Study of char-
acter state correlations among all genera of the
pancratioid Amaryllidaceae (Meerow, 1985, 1987a,
c) strongly suggests that flower size reduction (8),
loss of floral fragrance (9), flower number (10),
pedicel length (13), staminal tooth length (25), style
length (30), and reduction in ovule number (35
have evolved in this stepwise manner with no evi-
dence of reversal. Numerous ovules per locule (20
or more) characterizes all basal genera of the pan-
cratioid Amaryllidaceae and is generally considered
the ancestral condition for the family (Traub, 1962,
1963; Traub & Moldenke, 1949). Though the

evidence from phenetic studies of Eucharis (Mee-
row, 1987d, in press) and from study of other
genera of the pancratioid Amaryllidaceae (e.g.,
Meerow, 1987c) indicates that androecial char-
acters are among the most plastic morphological
characters in this group, examination of the evo-
lutionary patterns of staminal dentation (24) within
various genera (Meerow, 1987c, in press) suggests
that a reversal to the dentate state is unlikely once
dentation is lost completely. Complete loss of stam-
inal dentation often accompanies overall phenetic
divergence among the pancratioid genera (Meerow,
1985, 1987c; see E. astrophiala in this paper).
Polymorphism for the character is not uncommon,
however, and is conceived in the transformation
series as the intermediate between the two fixed
states of toothed or edentate stamens. Ordering of
pollen size (27) and exine morphology (28) is based
on data presented in Meerow (1985, 1987c) and
Meerow & Dehgan (1985), as well as unpublished
palynological data accumulated for many genera
in the family. A single character, chromosome
number (41), was coded in additive binary on the
basis of much literature on amaryllid cytology (Flo-
ry, 1976, 19777; Goldblatt, 1976; Lakshmi, 1978;
Meerow, 1984, 1987b; Ponnamma, 1978; Sato,
1938; Snoad, 1952), which strongly supports this
concept of chromosome number evolution.
Results and discussion.
monious trees without any differences in topology
resulted when either Pancratium or Lepidochiton
was used as the outgroup. The twelve trees differed
only in the branch lengths of a few internal nodes,
and resolution of terminal taxa did not change
among them. One of the twelve with Pancratium
used as outgroup is illustrated and discussed in
detail (Fig. 65). The cladogram has a length of
2.4 steps (fractional lengths are a result of weight
scaling), and a consistency index (Cl; Kluge &
Farris, 1969) of 0.487. Lepidochiton is the first
terminal EU to resolve in the cladogram after the
outgroup, Pancratium. Character state changes
from the outgroup to the ancestral node of Lepi-
dochiton (flower number reduction, globose seeds)
could not be polarized. Uniflory, perianth color
polymorphism, brown seed testa, and 2n = 34 are
the four apomorphies of Lepidochiton. The next
internal node of the cladogram is the hypothetical
ancestor to Eucharis, Caliphruria, and Urceolina,

E. sanderi, Eucharis subg. Eucharis, Caliphru-
ria, and Urceolina. Five apomorphies define the
ancestral node: densely striate abaxial cuticle, un-
dulate anticlinal walls (homoplasious with E. ama-
zonica), deeply cleft staminal cup, polymorphism
in staminal dentation, and lustrous testa. It is thus
obvious that subg. Heterocharis is paraphyletic

cladistically basal to the remaining EUs in the
cladogram and is defined by two apomorphies: a
reversal to dentate stamens and an increase in the
number. Fucharis lehmannii is
length of the teeth. The remainder of the cladogram
forms two monophyletic groups. All but two species
of Eucharis subg. Eucharis comprise one, and
Caliphruria, Urceolina, and E. oxyandra consti-
tute the second. Only two apomorphies define this
clade: reduction in floral fragrance and an increase
in flower number.
The three apomorphies at the ancestral node of
the Eucharis subg. Eucharis clade are subulate
free filaments (homoplasious with E. amazonica),
loss of exine dimorphism (homoplasious with the
ancestor of E. amazonica and E. moorei), and an
orange capsule. Within this clade, two monophy-
letic groups are evident. The larger of the two is
efined by a single apomorphy, plicate leaves. Eu-
charis formosa is the first terminal EU to resolve
but terminates a zero-length branch. Eucharis can-
dida also terminates a zero-length branch, the an-
cestral node of which is defined by two apomor-
phies: loss of floral fragrance and reduction in ovule
number. The next monophyletic group encom-
passes all species of subg. Eucharis with about five
flowers and about two ovules per locule. The hy-
pothetical ancestor of Eucharis astrophiala and
E. caucana forms an unresolved polytomy at the
ancestral node with E. cyaneosperma, E. ulei, and
the hypothetical ancestor of tetraploid species £.
bonplandii and E. bouchei.
Three apomorphies define the ancestral node of
the second clade within subg. Eucharis: a plicate
staminal cup, a reversal to shallowly cleft staminal
cups, and a reversal from polymorphism in staminal
dentation to fixed dentation. Eucharis bakeriana
is the first terminal EU to resolve, on the basis of
two apomorphies: loss of leaf margin undulation
and increase in pollen size. The remaining species
are the smallest-flowered species in the subgenus.
The remaining apomorphies at the ancestral node
are a decrease in pollen size and ovule number.
The first terminal EU to resolve is E. corynandra,
from a zero-length branch. It should be noted,
however, that two autapomorphies of this species,
a short staminal cup and club-shaped free fila-
ments, were not included in the data matrix. The
ancestor of the two subspecies of E. plicata form
a monophyletic group with E. castelnaeana on the
basis of style length. Subspecies brevidentata ter-
minates a zero-length branch. Kucharis castel-
naeana has the greatest patristic distance of the
three EUs (seven apomorphies)
The final large clade constitutes Caliphruria,
Urceolina, and the cladistically basal E. oxyandra.
Apomorphies are nonundulate leaf margins, small
flowers, loss of floral fragrance, urceolate corolla
(which does not apply to E. oxyandra, the corolla
shape of which is either crateriform or campanulate
but could not be coded as one or the other with
certainty), reduction of the staminal cup, loss of
androecial pigmentation, and moderately coarse
exine. The character state of E. oxyandra is un-
known for four of these seven. Within this mono-
phyletic group, Urceolina and the hypothetical
ancestor of Caliphruria resolve as sister groups
on the basis of three apomorphies: declinate or
pendent flowers via pedicel habit, straight tubes,
and small pollen grains. Nine and eight apomor-
phies define Urceolina and the hypothetical ances-
tor of Caliphruria, respectively. Within Cali-
phruria, the sole representative of the genus outside
Colombia, C. korsakoffii is the first terminal EU
to resolve, on the basis of three apomorphies:
straight anticlinal epidermal walls, short tubes
(homoplasious with C. tenera), and brown testa.
Caliphruria subedentata terminates a zero-length
branch from the hypothetical ancestor of the Co-
lombian species of the genus. Apomorphies at the
ancestral node are finely reticulate exines, loss of
exine dimorphism, compressed seeds, and rugose
testa (the states for the last two characters are
known only for C. subedentata). Caliphruria hart-
wegiana and C. tenera form a monophyletic group
on the basis of toothed stamens and reduced ovule
number, but C. hartwegiana terminates a zero-
length branch.

that exhibit three or more independent origins for

branches and unresolved polytomies. Invariably, it
is androecial characters (including pollen size) in
which a great deal of homoplasy has occurred.
Three of all the androecial characters, 24 (staminal
dentation), 25 (length of teeth), and 27 (pollen
size), are particularly homoplasious. When the data
matrix was run with only these characters deleted,
no change occurred in the resolution of terminal
taxa from the cladogram in Figure 65. Finally, the
data matrix was analyzed with all staminal cup
characters (19, 20, 21, 22, 23, 24, 25), and pollen
size (27) deleted. The resulting three cladograms
(differing only by one internal branch length) placed
Caliphruria and Urceolina within a monophyletic
group including E. bakeriana, E. bonplandii, and
. bouchei, on the basis of a single apomorphy,
nonundulate leaf margins.
Regardless of how the character-state data are
manipulated, a number of monophyletic groups
appear particularly robust. That Kucharis, Cali-
phruria, and Urceolina represent a monophyletic
group is uncontested. The monophyly of Eucharis
moorei and E. amazonica is also strongly sup-
ported, and these two species are the most cla-
distically basal of the eucharoid lineage. These
species have the greatest number of putatively
primitive characters and seem to represent the
more ancestral species in the genus. Nonetheless,
according to the cladogram in Figure 65, retaining
subg. Heterocharis in Eucharis renders the genus
paraphyletic. Subgenus Heterocharis is a fairly
heterogeneous group from the perspective of apo-
morphic characters alone. Each of the three species
may be characterized by autapomorphies, but only
plesiomorphies join them. By including subg. Het-
erocharis in Eucharis, Eucharis becomes para-
phyletic according to this cladogram. However, it
should be noted that it is unknown whether sec-
ondary petiolar bundles (which require fresh ma-
terial to observe), an important apomorphy which
links E. amazonica and E. moorei, are present in
E. sanderi. In the generalized sense, the distri-
bution of subg. Heterocharis is quite broad, from
Colombia to Peru (Fig. 64). However, each of the
three species of subg. Heterocharis itself are only
narrowly distributed. Fucharis sanderi is known
only from the Chocó region of Colombia. Eucharis
amazonica is found natively only in the middle
Rio Huallaga valley of Peru. Eucharis moorei has
been collected outside of Ecuador only once. More
significantly, E. moorei is the only species of Eu-
charis found on both sides of the Andes. I believe
that all three species of subg. Heterocharis rep-
resent the relictual remnants of the ancestral eu-
charoid complex, each of which has remained iso-
lated long enough to evolve its respective cohort
of autapomorphies.
The sister group relationship between Urceolina
and Caliphruria also seems to be a robust cladistic

logical intermediacy (androecium and pollen mor-
phology) between Eucharis and Urceolina. it is
known only from bulbs found in local, transient
cultivation in Peru, near the single recorded point
of geographic sympatry between Eucharis (E.
amazonica) and Urceolina (U. microcrater). The
absence of much character state data, but partic-
ularly those on fruit and seed morphology, further
occludes resolution of its phylogeny, and any of
several hypotheses concerning its origins are pos-
sible (see Taxonomic Treatment). Kucharis leh-
mannii, which usually resolves within a cladistic
“no man’s land" between paraphyletic subg. Het-
erocharis and all other clades, presents a similar
problem, though Regel’s (1889) figure strongly
suggests affinity to subg. Eucharis. In the initial
analyses, in which all multistate characters were
treated as unordered, this poorly known species
resolved as sister group to E. bouchei. 1 believe
that E. lehmannii is a sister species to E. caucana,
to which it bears much phenetic resemblance, and
that its unusual resolution in the cladogram is a
result of the great deal of missing character state
data. Fruit and seed morphology clearly place £.
caucana in subg. Eucharis, even though it shows
as much novelty as E. oxyandra or E. lehmannii
in other characters.
Excluding E. lehmannii and E. oxyandra, Eu-
charis subg. Eucharis forms

ovules per locule (E. astrophiala, E. cyaneosper-
ma, E. ulei, along with the tetraploids, E. bon-
plandii and E. bouchei) form a very natural group
with karyotypic similarity as well (Meerow, 1987b).
The sister species relationship of Eucharis cau-
cana to E. astrophiala within this group may be
as equivocal as the basal resolution of E. lehman-

Cical 1) mono-
nii, since it is based on two apomorphies (pollen
size and lack of staminal dentation), the latter of
which is highly homoplasious. I believe the reversal
in ovule number necessary for E. caucana to share
common ancestry with E. astrophiala is very un-
likely.
Eucharis candida and E. formosa, two often
sympatric (and possibly sibling) species, are cla-
distically close and basal to the five-flowered clade.
The small-flowered species (E. castelnaeana, E.
corynandra, and E. plicata) form another very

natural group. The position of E. bakeriana as
basal to this clade, largely on the basis of a plicate
staminal cup, may be equivocal. Karyotype anal-
ysis (Meerow, 1987b) suggests putative relation-
ship of E. bakeriana to E. formosa.
An alternative hypothesis of phylogenetic rela-
tionship is presented in Figure 66. The cladogram
is a user-generated tree in which Caliphruria and
Urceolina are placed as sister groups to a mono-
phyletic Eucharis. The topology of subg. Eucharis
in this cladogram represents my concepts of their
evolutionary relationships based on phenetic re-
semblance, phytogeography, and chromosome data.
The major differences from the cladogram in Figure
65 are the sister species relationship of E. caucana
and E. lehmannii, the ancestral node of which
forms a monophyletic group with the five-flowered,
two-ovuled species complex; and the positioning of
E. oxyandra as part of the small-flowered species
group of subg. Eucharis. This user-generated
cladogram had a length of 100.6 steps, with a CI
of 0.443. There are 82 parallelisms represented
among the character state changes, and re-
versals. The user-generated tree (Fig. 66) is thus
somewhat less parsimonious than the cladogram in
Figure 65. Of particular interest in the user-gen-
168
Annals of the
Missouri Botanical Garden
erated cladogram is the resolution of the larger
monophyletic groups constituting genera or sub-
genera, and the accompanying character state
changes within these clades.
In Figure 66, a monophyletic subg. Hetero-
charis is supported by seven apomorphies, four of
which are reversals (unordered characters not
counted). Some of these reversals are very unlikely
(e.g., reversal to larger, heavily fragrant flowers;
see previous discussion of ordered characters) and
would thus represent retention of ancestral states.
In the user-generated tree, a monophyletic subg.
Eucharis is supported by a greater number o
apomorphies (eight in Fig. 66) than in the parsi-
mony cladogram (three). Caliphruria as a mono-
phyletic group is best supported by Figure 66 (ten
apomorphies) versus eight in Figure
The results of these various cladistic treatments
illuminate the problems inherent in phylogenetic
reconstruction of large, character state
data sets, and particularly with taxa whose evo-
lution has involved large-scale homoplasy. The user-
generated cladogram in Figure 66 represents my
preferred hypothesis of phylogeny within the Eu-
charideae; nonetheless I cannot deny the com-
pelling evidence that Eucharis, by the inclusion of
subg. Heterocharis, may be paraphyletic.
From an orthodox cladistic perspective (Wiley,
1981), Traub's (1971) concept of a single poly-
morphic genus, Urceolina, is supported by the
criterion of parsimony. From a phenetic (and prag-
matic) standpoint, I find this unsatisfactory due to
the close phenetic relationship between subg. Het-
ris. This relationship is most
conspicuous if one compares Eucharis bakeriana
and E. formosa (the most basal species of subg.
Eucharis) with E. amazonica and E. moorei (subg.
Heterocharis). | prefer to recognize Urceolina and
Caliphruria as distinct genera, despite the atten-
dant risk of a paraphyletic Éucharis. I do not
believe that Urceolina and Caliphruria necessarily
erocharis and Eucha
share an immediate common ancestor—the three
apomorphies that define their sister group rela-
tionship in Figure 65 (reversal to straight tubes,
flower habit, and smaller pollen grains) are homo-
plasious within the Eucharideae as well as in other
tribes of the Pancratioidinae (Meerow, 1987c;
Meerow & Dehgan, 1985). Until further data allow
a more accurate understanding of their relation-
ships, I also prefer to maintain E. lehmannii and
E. oxyandra as species of Eucharis subg. Eucha-
ris, allied with the small-flowered species with nu-
merous ovules per locule. Without study of living
material, and particularly knowledge of fruit char-
acters, I am unwilling to declare E. oxyandra a
sister taxon to Urceolina and Caliphruria.
Ashlock (1971, 1972, 1979, 1984) has re-
peatedly argued for the acceptance of paraphyletic
groups in evolutionary systematic classifications.
He defined two subclasses of monophyletic groups:
holophyletic, which contain all descendents of the
stem ancestor, and paraphyletic, those which do
not. Ashlock (1979: 449) rejected ““the automatic
conversion of the cladogram into a classification.”
Meacham & Duncan (1987) have elaborated on
the term *'convexity," first proposed by Estabrook
(1978), which attempts to resolve the concepts of
monophyly, holophyly, and paraphyly. Meacham
& Duncan concluded that Ashlock's (1979) ad-
vocation of overa luti y similarity as a com-
ponent of classification schemes, rather than strict
cladistic topology alone, is sound, and they dis-
cussed the mitigating factors surrounding cladistic
methodology (e.g., uncertainty of character state
polarities, the speculative nature of phylogenetic
reconstructions, among others) which compromise
a direct translation of cladogram into classification.
and Humphries & Chappill (1988) have responded
vociferously to Cronquist's (1987) critique. Don-
oghue & Cantino (1988: 108) assail paraphyletic
higher taxa as “artificial classes created by tax-
onomists who wish to emphasize phenetic 'gaps',
and that formal recognition of such taxa conveys
a misleading picture of common ancestry and char-
acter evolution."
The enormous amount of homoplasy evident
within the highly canalized Amaryllidaceae creates
great difficulty in phylogenetic reconstruction
(Meerow, 1985, 1987c). In the analyses of Eu-
charis and related genera, missing character state
data further weaken the argument for adopting ad
hoc the most parsimonious phylogeny as the basis
for classification. At present, I prefer to accept a
less parsimonious phylogeny as represented by the
user-generated topology in Figure 66 until such
time as cladograms can be generated with consis-
tency indices greater than 0.5. Towards this end,
work is continuing with careful application of se-
lected character weighting (Neff, 1986; Wheeler,
1986).
In three neotropical lineages of the Pancratioi-
dinae, parallel trends in the evolution of floral mor-
phology have occurred (Meerow, 1985, 1987c).
In each case, taxa with smaller, tubular or ven-
tricose, brightly colored flowers with reduced stam-
inal connation, and without noticeable fragrance

Eucharis and Caliphruria
have apparently diverged from taxa possessing a
large, white, fragrant, crateriform flower with a
staminal cup (Meerow, 1985, 1987c). Each lin-
eage appears to be a monophyletic group on the
basis of vegetative and ovarian morphology, as well
as chromosome number (Meerow, 1985, 1987c;
Traub, 1963). A similar pattern occurs in all three
lineages: 1) floral morphology of “derived” taxa
3 gap an Lo TR pollination syndrome,
and 2) "derived" taxa are found, entirely or in
part, at iid elevations than apparent ancestral
taxa. Eucharis and Urceolina, as documented in
this paper, present one such case. Pseudosteno-
messon Velarde, submerged by Traub (1980) into
Hymenocallis as section Artema, presents a par-
allel situation within the Hymenocallis lineage
(Meerow, 1985; Meerow & Dehgan, 1985). Tribe
Stenomesseae contains two small genera, Pa-
mianthe and Paramongaia, with ancestral floral
morphology and contains a large genus, Steno-
messon, with derived morphology (Meerow, 1987c).
In the Hymenocallis and Eucharis lineages, the
pancratioid floral morphology has radiated to a far
greater extent than the putatively ornithophilous
divergence (Pseudostenomesson an rceolina,
respectively). In the Pamianthe- Paramongaia/
Stenomesson lineage, the derived genus, Steno-
messon (35-40 species), has speciated to a great-
er degree than taxa with the ancestral pancratioid
flower (Pamianthe: 2 species, Paramongaia:
monotypic).
he high level of divergence in neotropical pan-
cratioid tribes may be primarily a factor of two
causes, 1) the uplift of the Andes in the Pliocene
(van der Hammen, 1974, 1979), creating much
opportunity for geographic isolation, and 2) greater
genetic adaptability via tetraploidy to new ecolog-
ical zones. The occurrence of rare hybridization in
nature between the relict complex represented by
Eucharis subg. Heterocharis and both Caliphru-
ria (X Calicharis butcheri) and Urceolina (x Ur-
ceocharis edentata) may be further indication that
the evolution of these genera was geologically re-
cent.
TAXONOMIC TREATMENT
SUBSPECIFIC TAXA
The rank of subspecies is used once in this
treatment (E. plicata) to designate strong mor-
phological divergence coupled with geographical
isolation that I accept within specific limits. The
rank of variety is used in a case (E. bouchei) where
both the morphological and geographic components
of divergence are weaker but appear to represent
the first stages of speciation within a tetraploid
semispecies complex (Meerow, 19874).
CRITICAL MEASUREMENTS
Measurements of vegetative and floral parts in
the following species descriptions are derived from
examination of dried material (floral parts after
rehydration in 3% solution of Aerosol OT brought
to boil) supplemented with examination of fresh or
FAA-preserved material when available. 1 found
less than 5% difference between measurements of
dried and fresh or spirit-preserved material of the
same collection when available.
A NOTE ON THE KEYS
Species of Caliphruria and penas subg. Het-
erocharis are separable by di ters very
amenable to key construction. dia the keys to
these two groups, any worker should be able to
identify material referable to described taxa wheth-
er in the field or the herbarium. The enormous
degree of variation exhibited by species of subg.
Eucharis, however, made key construction difh-
cult. A number of the species overlap to at least
some degree with one or more other species in
virtually all quantitative morphological characters.
As a consequence, sometimes I have had to rely
on characters observable only with living material.
With perseverance, it should be possible to key out
all but the most depauperate herbarium specimens
of subg. Eucharis. Collectors should note such
characters as leaf plication and undulation, floral
fragrance, tepal habit, and pigmentation and pli-
cation of the staminal cup in their notes when
preparing specimens of Eucharis.

Eucharis candida was originally described from
cultivated material supposedly originating from Co-
lombia, a country in which it has been encountered
only rarely. The species previously has been de-
limited by the absence of staminal dentation; how-
related species E. formosa and E. ulei. Peruvian
populations of E. candida are variable in the shape
of the staminal cup (Figs. 68, 69), even among
flowers of the same inflorescence.
Eucharis candida is most common throughout
the upper Napo Valley in eastern Ecuador and is
very often sympatric with the larger-flowered and
Variation in a single Peruvian population of Eucharis candida pu 14155-B, FLAS).—
69. Flower with cylindrical staminal c
more widely distributed E. formosa (Figs. 71, 72).
In one instance, two specimens (Harling & An-
dersson 11719), one each of the two species, were
collected under the same number. To date, no
species of Eucharis other than these two have been
collected north of the Pastaza valley in eastern
Ecuador. On the basis of herbarium study alone,
Ecuadorean populations of these two taxa form a
mosaic that seemed taxonomically insoluble until
living material of both species from several pop-
ulations was collected and flowered. Phenetic and
karyotype analyses (Meerow, in press) support their
recognition as distinct species and suggest that E.
E. formosa have hybridized in at
least one area of sympatry.
Eucharis candida may be separated from E.
formosa by its smaller leaves and flowers, complete
candida an
absence of fragrance (E. formosa produces a mild,
"sour" odor), and generally fewer ovules per locule
(though both species are variable in ovule number).
On the basis of known collections, Eucharis for-
mosa is slightly better represented in the Pastaza
valley than E. candida.

Eucharis formosa is the most commonly en-
countered species in eastern Ecuador (Fig. 71). It
extends into Amazonian Peru and Colombia and
occurs in the lower “ceja de la selva" forests of
north-central Peru (Fig. 72). Like the closely re-
lated E. candida, E. formosa has a wide elevati
range, possibly in part from cultivation oe
1987e). The flowers emit a mild and unpleasant
“sour” odor. Eucharis formosa is larger in all parts
than E. candida and generally has more ovules
per locule. The conspicuous horn on the apiculum
of the outer tepal is characteristic of Ecuadorean
populations of E. formosa (Fig. 67Ai); this char-
acter is not obvious in Peruvian collections. Forms
with toothed or edentate staminal cups occur
throughout the range of this species without any
observable geographic pattern (Fig. 70B). Flowers
of the same inflorescence can vary for this char-
In floral morphology (Fig. 78), however, it is in-
distinguishable from other Ecuadorean material. A
second collection (Schunke 1417 1), from the same
general vicinity of Peru as Schunke 14174, has
only shallowly plicate leaves and reduced pigmen-
tation of the staminal cup (Figs. 76, 77). At pres-
ent, too little is known about E. formosa in Peru
to justify recognition of subspecific taxa.

al. 37852 (MO); vicinity of Tarapoto, no other data,
flowered in cultivation from material collected by L. Besse,
Meerow 1108 (FLAS).
The type of E. bakeriana was prepared from
living material supposedly collected in Colombia.
When I examined the type specimen, only the
several large flowers present in the fragment packet
resembled the figure that accompanied Brown's
(1890) description of E. bakeriana. The mounted
material was referable to the smaller-flowered F.
candida. At the time, I thought that E. bakeriana
might represent an aberrant form of E. candida.
Several years later I received a bulb of a Eucharis
collected near Tarapoto, Peru, by Libby Besse of
SEL. The flowers that grew from the bulb bore
an exact resemblance in habit and staminal cup
morphology to E. bakeriana, though with consid-
erably more ovules per locule. At present, E. baker-
iana is known only from the type, the Besse ma-
terial, and a fruiting specimen referred to this species
on the basis of leaf size
Eucharis bakeriana is distinct from E. formosa,
its closest phenetic relative, by its nonpendent flow-
ers that are perpendicular to the vertical axis of
the scape, very shallowly cleft staminal cup (« 1
mm, vs. 2 mm in E. formosa), short subulate
portion of the stamen, and sweet floral fragrance
(slightly fetid in E. formosa). In leaf size and karyo-
type, E. bakeriana is very similar to Peruvian
material of E. formosa (Schunke 14174) but dif-
fers by its greater number of subtelocentric chro-
mosomes and the submetacentric morphology of
the second-largest pair (Meerow, 1987b). The leaves
are only shallowly, if at all, plicate and are thicker.

Eucharis bonplandii is one of only two tetra-
ploid (2n — 92) species so far known in the genus.
The species is known only from Colombia, and has
been rarely collected. Among Amazonian species,
E. bonplandii has the greatest phenetic relation-
ship to E. ulei, with five similarly sized flowers and
two ovules per locule in common. It may be sep-
arated from £. ulei by having succulent, glaucous
leaves and short petioles. The staminal cup of F.
bonplandii is pigmented pale yellow at its base;
that of E. ulei is marked green. Eucharis bon-
plandii and E. bouchei are the northernmost species
of subg. Fucharis, and thus may form a mono-
phyletic, tetraploid group (Meerow, 1987d). Both
species have relatively short petioles. From PF.
" m E. bonplandii differs primarily by its leaf
glaucousness and longer pedicels.

Eucharis bouchei is the northernmost species
of Eucharis, and the only species found north of
the Darién Gap. It is also the most variable species
in the genus, in characteristics that elsewhere jus-
tify specific delimitation. Patterns of variation in
floral size and tube and limb habit form a complete
mosaic throughout the range of E. bouchei that
shows little or no geographic consistency (Meerow,
19874). Staminal cup morphology (Fig. 70C) does,
however, demonstrate a fair degree of geographical
consistency, and it is chiefly on this basis that I
have recognized var. bouchei and var. darienensis.
Variety dressleri, rarely enountered mixed with
var bouchei, presents a special case, discussed
below.
Variety bouchei, most common around El Valle
de Antón in Coclé Province, is recognized by its
largely edentate staminal cup in which the trape-
zoidal free filament is not markedly constricted
distally into a narrow subulate portion (Figs. 70Ci,
ii, 82C). The staminal cup of "a darienenis,
found both in Panamá and Darién provinces, is
obtusely bidentate or lobed (Fig. 70Civ) The free
filament constricts distally into a narrow (< 2 mm)
subulate portion. These two varieties occur in close
proximity in one location, near Cerro Campana in
Panamá Province (Fig. 83).
The rare var. dressleri (Fig. 82Ai), with its
acutely toothed staminal cup (Fig. 70Ciii) and shal-
lowly trigonous ovary, occurs close to populations
of var. bouchei, which is an unstable tetraploid,
producing at least some cells with diploid (2n —
46) chromosome number (Meerow, 1987d). This
variety also does not express either heterozygous
or additive banding phenotypes for isozymes o
aspartate amino transferase, which otherwise char-
acterizes electrophoretic phenotypes of E. bouchei
(Meerow, 19874).
The unprecedented degree of variation in £.
bouchei is likely the result of two main factors: (1)
the species is tetraploid, and (2) it probably rep-
resents a geologically recent colonization of Central
America by this primarily northern Andean and
Amazonian genus (Meerow, 19874).
Northwesternmost populations representing var.
bouchei have the most derived androecial mor-
phology (Fig. 70Ci, ii) relative to southeasterly
populations (var. darienensis, Fig. 70Civ). The
latter have staminal cups similar to the generalized
morphology characteristic of Andean and Ama-
zonian species of subg. Eucharis. This suggests
that general movement of E. bouchei in Central
America has been away from the Colombian bor-
der. The occasional presence of E. bouchei in Costa
Rica is not surprising, but the two reported collec-
tions from Guatemala (Wendland 207 and Skutch
1585) represent a substantial disjunction, or two
disjunctions, since the two collections represent
different varieties. Given the history of cultivation
of Amazonian Eucharis by Indian people for me-
dicinal, ceremonial, and possibly ornamental use,
the same may have held true in Central America.

uration of E. caucana (2n — 138, type collection). Thirteen chromosomes are out of the figure frame
chromosome pair of E. astrophiala is submeta-
centric, unlike the metacentric pair of all other
species of the genus I have examined (Meerow,
1987b). It is the only species of the subgenus found
exclusively on the western slopes of the Andes south
of Colombia. It occurs sympatrically in some lo-
calities (fide Dodson & Gentry 12815 and Meerow
& Meerow 1140) with E. moorei, though the latter
grows at slightly higher elevation in these areas.
Eucharis astrophiala is the only species of subg.
Eucharis that enters a definite rest period during
the short dry season of the northwestern and cen-
tral western Ecuadorean Andes. New growth com-
pletely ceases, though one or two leaves may persist
for the duration.

The recent receipt of material collected by Phil
Silverstone-Sopkin and coworkers is the first col-
lection of the subgenus in the largely deforested
Cauca valley since 1922.
Eucharis caucana has the largest pollen grains
in the genus and is the only known hexaploid species
of Eucharis, with a somatic chromosome number
of 2n — 138 (Fig. 88). As with most other South
American peripheral isolates from the Amazonian
center of distribution for subg. Eucharis (E. asto-
phiala, E. corynandra, E. lehmannii, and E. ox-
yandra), E. caucana exhibits some degree of mor-
phological novelty; in this case, reduction of staminal
connation, funnelform-campanulate perianth, and
very large pollen grains. Nonetheless, E. caucana
has fruit and seed morphology typical of subgenus
Eucharis. By its reduced staminal cup E. caucana
shows affinity with E. lehmannii from which it
differs by having larger flowers, shorter pedicels,
straighter tubes, edentate androecia, and fewer
ovules per locule. By its high polyploid chromosome
number, short pedicels, and flower size, E. caucana
shows similarity to certain populations of E. bouch-
ei var. bouchei. Some collections of the latter from
Colón Province exhibit funnelform-campanulate
perianth morphology and floral tube habit like E.
caucana. The discovery of this hexaploid species
in Colombia supports the hypothesis that a poly-
ploid complex of Eucharis may have existed in
Colombia in the recent geologic past (Meerow,
987d).

Eucharis ulei is among the more widespread
Amazonian taxa of subg. Eucharis, extending north
from its Peruvian center of distribution into Co-
lombia and south to Bolivia (Fig. 81). The species
is best recognized by its primarily narrow-elliptic
leaves, chiefly five-flowered inflorescence, tube
length of ca. 3-4 cm, limb spread of 4-5 cm, and
reduced ovule number (generally two per locule,
Fig. 89C). Both flower and ovule number have
become nearly fixed throughout the range of the
species. Eucharis castelnaeana is sympatric with
E. ulei at times but tends to occur on seasonally
inundated soils. Flower size and number, ovule
number, and chromosome morphology (Meerow,
1987b) suggest close relationship to E. cyaneo-
sperma, which has different tube morphology, a
deeply trigonous ovary, and blue-coated seeds.
Ravenna (1982: 50) described Urceolina moana,
citing the “absence of lobes, or teeth, in the cup."
The single, poorly preserved, fragmentary flower
of the holotype, however, had stamens at least
shortly dentate to quadrate. As in E. candida and
E. formosa, androecial toothing in E. ulei has little
taxonomic significance. The androecial morphol-
ogy of E. moana is well included within the range
of variation for this character in £. ulei (Fig. 70D)—
several collections of E. ulei have completely eden-
tate staminal cups (e.g., Meerow et al. 1024, Plow-
man & Kennedy 5811, Prance et al. 13915).
Much the same argument applies to the likewise
synonymous E. boliviensis (Ravenna, 1988), rep-
resented by the only specimen of E. ulei collected
in Bolivia. The only other collection assigned by
Ravenna (1988) to E. boliviensis (Cardenas 1553)
belongs to E. cyareosperma. Eucharis ipariensis,
inexplicably described by Ravenna (1982) as allied
to E. mastersii (= E. x grandiflora of subg. Het-
erocharis), is also indistinguishable from numerous
collections of E. ulei.
Krànzlin (1913) and Macbride (1936) noted the
dissimilarity of the two specimens comprising the
holotype of E. ulei (Ule 57376), one in flower, the
other in fruit. I have assigned the fruiting specimen
(Ule 5737b), with blue seeds, to E. cyaneosperma
Meerow. When a putative isotype of Ule 5737
was received from MG, it proved to represent E.
castelnaeana. Ule thus collected three species un-
der a single number, an unsurprising occurrence
in areas where several Eucharis species are sym-
patric.

Eucharis cyaneosperma is the only species of
Eucharis with blue-coated seeds. The species ap-
pears very similar to E. ulei but differs by having
usually shorter leaves, different tube morphology
(abruptly curved at the base in E. cyaneosperma,
sinuously curved in F. ulei), irregularly dentate to
quadrate staminal cup (Fig. 89A), deeply trigonous
ovary, and different seed color. In the southern
part of its range, E. cyaneosperma occupies more
upland sites than are usually characteristic of F.
ulei.

Eucharis lehmannii is known only from the
fragmentary type (a single flower) and a single
specimen at Kew with only one flower present. An
Ecuadorean specimen mislabeled as the type of E.
lehmannii, received from Kew (Lehmann 7775),
turned out to be E. astrophiala (Ravenna) Ra-
venna. Like E. caucana, to which it may be very
closely related, E. lehmannii is a peripheral isolate
of subg. Eucharis, with novel androecial character
states. Despite the unusual staminal morphology,
the plant figured in Regel's (1889) description re-
sembles Eucharis subg. Eucharis by overall mor-
phology and habit of the flower. In 1984, I was

In size and number of the flowers, as well as
ovule number, Eucharis corynandra shows affinity
to E. castelnaeana (Baillon) Macbr. and to E.
plicata Meerow. The short staminal cup and dis-
tinctive club-shaped free filaments (Fig. 90H) are
the principal unique characters of this species. I
cannot, however, confirm Ravenna's (1978) de-
scription of the anthers as densely pubescent. The
collection locality suggests that it is an upland
isolate from the Amazonian center of the subgenus,
the plant having colonized the lower limits of the
“ceja de la selva" forest formations in Cajamarca
Department of Peru.

This unusual species has the smallest staminal
cup of any Peruvian species of Eucharis subg.
Eucharis (Fig. 90B). The long, almost linear, free
filaments are another unusual feature of the an-
droecium. The polymorphism of the staminal cup
(both edentate and obtusely dentate forms repre-
sented in the isotypes, Fig. 90B) is puzzling and
adds further credence to my suggestion that this
character has been over-weighted as an indicator
of species delimitation in the alpha-taxonomic lit-
erature relating to the genus. Alternatively, it is
possible that the two bulbs found by the collector
and representing this species were of two different
origins.
In publishing Urceolina oxyandra, Ravenna
(1983) was apparently unaware of the unusual
situation in which the species was found, having
examined only a duplicate at USM, which seems
to have lacked the detailed field notes of the col-
lector. He argued that the unusual morphology of
the androecium (reduced staminal cup and long,
narrowly subulate filaments), similar to that of Ur-
ceolina, supported the inclusion of Eucharis within
Urceolina (Traub, 1971), a position he recently
reversed (Ravenna, 1985). This type of androecial
morphology is characteristic of two putative inter-
generic hybrids between Eucharis and Urceolina,
X Urceocharis edentata Wright (1910) and x U.
clibranii Masters (1892).
Given that the plant was discovered as an artifact
of cultivation in company with a bulb of Urceolina,
and in a geographic area of loose sympatry for the
two genera, I thought it possible that E. oxyandra
might represent a hybrid between Eucharis and
Urceolina. X Urceocharis edentata was suppos-
edly collected in the wild in Peru (Wright, 1910).
Pollen of E. oxyandra, however, stains 100% with
Alexander's (1969) stain. Both x U. edentata and
X U. clibranii produced very little pollen (Wright,
1910), an observation confirmed when I examined
specimens of both hybrids (ex hort. BM). Pollen
grain size of the species is more like that of Eu-

Eucharis and Caliphruria
charis subg. Eucharis, but exine sculpturing re-
sembles that of Urceolina (Meerow & Dehgan,
1988). Fertile hybrids between closely related gen-
era are not unknown in Amaryllidaceae (Traub,
1963).
Alternatively, Eucharis oxyandra might be a
relict taxon close to the ancestor of Urceolina, a
genus whose divergence from Eucharis may have
been relatively recent (see previous section). Phy-
logenetic analysis supports this latter hypothesis.
At present, it seems best to treat E. oxyandra as
a species of Eucharis, even though its known shared
characteristics with Eucharis are plesiomorphic,
since its phylogenetic relationships are obscured
by the large amount of unknown character state
data. As in E. astrophiala, E. caucana, E. cor-
ynandra, and E. lehmannii, this species exhibits
a pattern of morphological novelty characteristic
of peripheral isolation in Eucharis.

Distribution. Known only from the type lo-
cality, where it is locally abundant (Fig. 91). This
population appears to have hybridized with E. ulei
and contains a range of intermediate morphs in
addition to true E. plicata. The intermediates show
reduced pollen stainability, the presence of non-
homologous chromosomes, and extreme allozyme
heterogeneity. It is unclear whether these represent
a highly variable F,, the F,, or the results of in-
trogression with E. plicata subsp. plicata. An anal-
ysis of this population is in preparation.

Eucharis plicata is phenetically and cladisti-
cally closest to E. castelnaeana. The phenetic re-
lationship between the two species is most evident
in E. plicata subsp. brevidentata, which in char-
acteristics of the staminal cup and ovule number
is intermediate between subsp. plicata and E. cas-
telnaeana. From the latter, E. plicata may be
distinguished by its wider leaves and tepals, larger
flowers, campanulate staminal cup which is plicate
along the filamental traces (Fig. 92E), more nu-
merous ovules, and fruit and seed morphology typ-
ical of subg. Eucharis.

Eucharis castelnaeana has been collected most
frequently in the vicinity of Yurimaguas in Peru

(Fig. 91) and is sometimes locally abundant in rain Subgenus Euch ffini imis differt florib
forest understory. It has the smallest flowers of
any species in subg. Eucharis and is the major
exception to the correlation of reduced flower size
with loss of fragrance that otherwise characterizes
Eucharis. Several living collections produce a mild
lemon scent when ambient temperatures are high
(as does E. plicata var. brevidentata). It is the
only species of subg. Eucharis in which the ripe
capsule is not leathery and orange. The glaucous,
green, thin-walled capsule is tardily dehiscent and
can abscise without opening, though the seeds with-
in are fully ripe.
Eucharis castelnaeana is autogamous. Under
greenhouse cultivation it is the only species of
Eucharis that successfully sets fruit with self-pol-
len. Unmanipulated inflorescences regularly set 50-
75% of their capsules.
Eucharis castelnaeana is variable in leaf and
flower size (Fig. 93A) and, to a lesser extent, in
androecial morphology. In his description of E.
narcissiflora, Huber (1906) made reference to £.
castelnaeana, described from the same location as
Huber's type of E. narcissiflora, but differentiated
his new species solely on the basis of size. The two
taxa represent the extremes of size diversity of a
single species and differ by no other characters.
Populations represented by Schunke 14154a (Fig.
93Ai) have flowers almost twice as large as those
of Schunke 14156 (Fig. 93Aii) but are otherwise
indistinguishable. Shape of the staminal cup in the
latter collection can range from nearly cylindrical
to funnelform-c ylindrical.
Eucharis plicata is phenetically the closest
species to E. castelnaeana. Baillon (1894) consid-
ered E. castelnaeana intermediate between Cali-
phruria and Eucharis in his argument for com-
bining these two genera. Baillon probably weighed
flower size heavily in his judgment, one of only two
characters by which E. castelnaeana resembles
Caliphruria. In Baillon's time, most other small-
flowered Eucharis species were not yet described.
Additionally, the green, thin-walled capsule of £.
castelnaeana is like the fruit of Caliphruria. Bail-
lon (1894) gave no indication whether he was fa-
miliar with the fruit of either Eucharis or Cali-
hruria. Nonetheless, perianth and pollen exine
morphology place E. castelnaeana squarely in Fu-
charis despite its aberrant fruit and seed mor-
phology.

Eucharis X grandiflora has long been confused
with E. amazonica Linden ex Planchon (Meerow
& Dehgan, 1984a). Meerow € Dehgan (1984a)
re-established E. grandiflora (without hybrid des-
ignation) as distinct from E. amazonica in Eucha-
ris subg. Heterocharis. At the time, I considered
E. lowii and E. mastersii to be distinct but closely
related to E. x grandiflora. In 1984, I collected
material in Colombia referable to E. lowii Baker
and received living material of E. mastersii col-
lected in Ecuador. According to Baker (1893), who
described these two species from cultivated ma-
terial, E. lowii had a staminal cup half as long as

that of E. “grandiflora,”
amazonica or E. moorei (as E. grandiflora var.
probably referring to E.
moorei Baker). When I compared the staminal cup
of E. lowii with that of the lectotype of E. x gran-
diflora, the synonymy of E. lowii with E. X gran-
diflora became evident. The two seemed identical
in all respects. Baker considered E. lowii to be a
hybrid of E. mastersii and E. “grandiflora” and
E. mastersii Baker (1885) to be a hybrid between
E. sanderi and E. “grandiflora.” Baker distin-
guished E. lowii from E. mastersii merely by the
former's slightly longer-exserted staminal cup, which
does not hold up. I now believe that E. mastersii
and E. lowii are elements of a slightly variable
hybrid taxon, E. x grandiflora, a putative hybrid

a collection of this hybrid that Planchon & Linden

X grandiflora appears intermediate in all respects
to E. moorei and E. sanderi. Virtually all collec-
tions of E. x grandiflora are from cultivated pop-
ulations in Colombia and Ecuador according to
specimen labels. Pollen stainability of either Co-
lombian or Ecuadorean collections of E. x gran-
diflora is never better than 10%, and I have not
succeeded in obtaining seeds in cultivation with
Eucharis
either sibling pollen or pollen of other species. The
hybrid is slightly variable in leaf morphology, num-

This species is characterized by its large, sweetly
fragrant funnelform-campanulate flowers, large
ovaries and capsules, and reduced staminal cups.
“Natural” hybrids exist between E. sanderi and
oth E. “moorei” (E. x grandiflora) and “Cali-
phruria subedentata" (X Calicharis butcheri).
Despite the many putatively primitive character-
istics of E. sanderi (e.g., large flowers, strong fra-
grance) in common with E. moorei, ovule number
of E. sanderi is highly variable, and its leaves are
deeply plicate. The reduced morphology of the
androecium is the major advanced character of E.
sanderi.

This putative hybrid between E. sanderi and
Caliphruria subedentata was first described by
Baker (1885) as Eucharis sanderi var. multiflora.
It has been collected in the wild at the interface
of p^ NUR dde of both parents and at inter-
. The plant produces little pollen,
none of it aid with Alexander's (1969) stain.
Floral morphology is intermediate between both
parents, although, like C. subedentata, the stig-
matic papillae are multicellular. There is some
karyological evidence of hybrid intermediacy as
well (Meerow, 1987b).

Meerow & Dehgan (1984a) re-established Eu-
charis amazonicas distinct from E. x grandiflora,
a taxon with which it has been confused since its
description by Planchon (1857). The species is
indigenous only to Peru, in the upper and middle
Huallaga valley, but is grown worldwide in tropical
regions and may be sporadically adventive. The
species has a somatic chromosome number of 2n
— 68 (Meerow, 1987b; Nagalla, 1979) and is at
least partially sterile. No specimen of E. amazon-
ica, in contrast to most other species, has ever
been collected in fruit; pollen stainability is only
50-65%; and viable seed has never been produced
in cultivation. It is therefore conceivable that all
populations of E. amazonica constitute a single
clone. Its distribution throughout its narrow v range
cultur-
possibly extinct mutual ancestor. The morpholog-
ical differences between these taxa are cryptic and
virtually impossible to discern in most dried ma-
terial without dissection of the ovary. Their close
relationship is further supported by the presence
of secondary vascular bundles in the petiole of both
taxa, although much smaller in E. amazonica.

cited as E. galanthoides (Klotzsch) Linden (e.g.,
by aS 1936; Traub, 1963), Ann. Cat. Hort.

erroneous assumption that Linden's Kucharis ga-

Klotzsch (Meerow, 1987a). The actual basionym
was Pancratium galanthoides, a name under which
Linden received material of a Eucharis collected
by Gustav Wallis in Amazonas. Mathieua galan-
thoides was collected by Warscewicz in xeric,
northwestern Peru (Warscewicz s.n., o type

E. galanthoides merely appeared as a listing in

Caliphruria subedentata is the most common
and variable species of Caliphruria, at one time
found throughout the moist lower and middle mon-
tane forests of the slopes of the cordilleras Central
and Occidental west of 76°W longitude (Fig. 105),
and chiefly those surrounding the Cauca Valley.
Much of this forest type has been destroyed in
western Colombia so the species is no longer abun-
dant. In the course of fieldwork in western Colombia
in 1984, I was not able to find C. subedentata in
its historical localities nor in the remnants of lower
and middle montane forest that 1 explored. The
species may yet persist in more inaccessible for-
ested sites. Living material received from Mr.
Thomas Fennell was said to have been collected in
Ecuador, but this information is undocumented. At
present, I have seen no Ecuadorean specimens of
Caliphruria, nor encountered populations in the
eld
Within the range of C. subedentata, variation
in leaf size, flower size, dentation of the androecium
(Fig. 104C, D), and number of ovules is evident,
but these patterns are for the most part continuous
and/or mosaic in distribution, rendering recogni-
tion of subspecific taxa inappropriate. Though Ba-
ker (1877) characterized the species by the pres-
ence of one or two small teeth between the free
filaments, the flowers present on the type specimen
of C. subedentata are completely edentate. Clono-
typic material of the taxon described by Traub
(1951) as E. fosteri is distinguishable from other
living material of C. subedentata only by its slightly
smaller leaves and flowers.

lombian representative of Caliphruria. It is readily
distinguished by its hysteranthous leaves and the
long teeth of the androecium which greatly exceed
the short free filament (Fig. 104A). Unfortunately,
C. tenera has not been re-collected since 1853.
The hysteranthous leaves of this species suggest
adaptation to drier habitats than usually charac-
teristic of the genus. Pockets of xeric vegetation
do occur in the vicinity of the type locality (Cua-

Caliphruria korsakoffii is the only species of
Caliphruria presently known outside of Colombia.
In the size of the flower this species has affinity
with C. tenera but can be distinguished by having
evergreen leaves, subcylindrical tubes, and eden-
tate, divergent, and longer stamens (Fig. 104E),
coarser pollen exine reticulation, more numerous
ovules, and higher altitudinal limits. The seeds of
C. korsakoffii have a brown testa; those of C.
subedentata are black. The ridged cuticle of the
abaxial leaf surface of C. korsakoffii (Fig. 12) is
quite different from the narrow cuticular striations
C. subedentata (Fig. 11). The morphological
novelties exhibited by C. korsakoffii suggest con-
siderable isolation from the Colombian taxa of Cal-
iphruria.

ABSTRACT
Ludwigia sect. Microcarpium, which consists of 14 species distributed mainly in the southeastern United States,
is the second-largest section in the genus, the largest being the phylogenetically central sect. Myrtocarpus of South
merica.
Plants of Ludwigia sect. Microcarpium are morphologically diverse; they form a polyploid complex of four diploids,
eight intr two hexaploids, and one octoploi oid. They are facultatively autogamous herbaceous plants capable of
reproducing both sexually and asexually (forming stolons late in the flowering season). Based on extensive crossing
experiments as well as field and Reden studies, the relationships among species of this section iut been clarified.
Internal genetic barriers iem species are nonexistent, and natural hybridization is fairly common.
Among the diploid species, L. linifolia and L. linearis have very narrow leaves, petaliferous Add and elongate
capsules. The two species, oweve r, differ chromosomally by one réim sall translocation. F, hybrids between them
are vigorous, have ca. 50% sta huile pollen, and produce acces quantities of viable seeds. Ludwigia stricta, the
Cuban endemic, is apparently most closely allied to L. linifolia, based on morphological evidence, but has not yet
been studied biosystematically. udwigia microcarpa, in contrast, has spatulate-obovate leaves, small, apetalous
owers, and minute obconical capsules. Artificial hybrids between L. microcarpa and either L. linearis or L. linifolia
form neither stainable pollen nor seeds; for the most part, the chromosomes of War To do not pair in meiosis.
crossed in any direction in the experimental ues and form fertile F, onn d Natural e in plants of
this group are also fairly common and in some cases blur the boundaries of the species. Somewhat surprisingly, none
of the extant diploid species are considered to be direct ancestors of the tetraploids, based on cytogenetic studies.
The two hexaploid species, L. alata and L. simpsonii, are not closely related to each other. The affinity of L.
lata is definitely with the tetraploid species group. Hybrids between L. alata and any other tetraploid species
consistently exhibit a modal configuration of 16 II and 8 I in meiosis. Based on de morphology and the cytology of
hybrids involving it, L. alata may have originated through hybridization between a tetraploid species, possibly L.
lanceolata, and the diploid L. microcarpa, or populations ancestral to each of these Epa
udwigia simpsonii, on the other hand, is closely related to L. curtissii, which is the only octoploid in sect.
Microcarpium. The two species are unique in sect. Microcarpium in having loculicidal capsules and, together with
the diploid L. microcarpa, in having spatulate-obovate cauline leaves. Cytogenetic and morphological studies suggest
that the octoploid L. curtissii may have resulted from hybridization of L. s simpsonit and a petaliferous diploid species,
possibly L. linifolia, L. linearis, or populations like them. Ludwigia microcarpa is involved in the formation of the
hexaploid L. uS and ide ore that of the octoploid L. curtissii. The other progenitors of L. simpsonii are
not clear, but some species in sect. Dantia or populations ancestral to them with apetalous FR T caite leaves,
and a prostrate pem are likely andes

Ludwigia is a distinct genus of Onagraceae and
is the only member of Jussiaeeae. Fossil records of
pollen suggest that it is archaic and has existed at
least 50 million years since the middle Eocene in
both the Northern and Southern hemispheres (Gon-
zales Guzmán, 1967; Rouse, 1962; Bratseva,
1969). Except for its chromosome structure and
number, which appear to be relatively specialized
(Kurabayashi et al., 1962), Ludwigia is one
of the least specialized genera as to wood anatomy
(Carlquist, 1975, 1982), floral anatomy (Eyde,
1977, 1978, 1981), and leaf anatomy (Keating,
1982). Based primarily on its unusual nectary po-
sition, ovular vasculature, and independently de-
rived epigyny, Eyde (1977, 1978, 1981) dem-
onstrated that Ludwigia represents a distinct
branch from the common ancestor of the family,
with all other living genera on the other branch;
in Hennigian terms, it is the sister group of the
remainder of the family.
The genus Ludwigia comprises 82 species that
are diverse enough, especially in fruit, seed, and
flower characters, to be classified in 23 sections,
14 of which are monotypic (Raven, 1963; Ra-
mamoorthy & Zardini, 1987). Plants of Ludwigia
are adapted to wet habitats in the tropics and
subtropics. They probably originated in South
America, the most important center of diversity
for Ludwigia, and the area where the most prim-
itive species are found (Ramamoorthy & Zardini,
1987). The genus, however, is also well represented
in temperate North America and has three endemic
species in temperate Asia.
In North America, there are 23 native Lud-
wigia species, characterized by having convex or
elevated nectaries, tetramerous, haplostemonous
flowers, pluriseriate ovaries, free seeds with narrow
raphes, and herbaceous habits. Most of these plants
are confined to the Atlantic and Gulf coastal plains
of the United States, although some species are
more widespread, and some extend into the islands
of the Caribbean; one is endemic in Cuba. Based
primarily on characters of capsules, mode of per-
ennation, and phyllotaxy, the North American plants
are classified into sect. Ludwigia (4 species), sect.
Dantia (DC.) Munz (5 species), and sect. Micro-
carpium Munz (14 species). Table 1 summarizes
the diagnostic characters of these three sections.
Based on his study of the structure and mor-
phology of the capsules and nectaries of Ludwigia,
Eyde (1981) considered sections Dantia and Mi-
crocarpium to comprise a closely knit group de-
rived from the phylogenetically central, diploste-
monous Myrtocarpus complex, whereas sect.
Ludwigia is different enough to have arisen in-
dependently from the Myrtocarpus complex.
Section Microcarpium was selected for the pres-
ent revision because it is the second-largest section
of Ludwigia and is very diverse, because it has
not been revised in light of recent new data and
evolutionary concepts, and because several species
of this section are variable and taxonomically dif-
ficult, with boundaries between species often blurred
by intermediates.
he purposes of this revision are to clarify species
limits, to determine the degree and significance of
natural hybridization, and to analyze natural affin-
ities among species of sect. Microcarpium. Toward
this end, more than 7,000 specimens from 44
herbaria have been consulted for morphological
studies and for mapping. Furthermore, I have made
three extensive field studies in the coastal plains
of the southeastern United States. Searches for
possible natural hybrids were made in the field
whenever taxa occurred sympatrically. Seeds and/
or clonal transplants of all species were propagated
at the Missouri Botanical Garden for chromosome
determination and morphological study.
TAXONOMIC HISTORY
After the establishment of the genus Ludwigia
in 1753 by Carl Linnaeus, the first group of North
American species of sect. Microcarpium was dis-
covered by the British botanist Thomas Walter
(1788). Four of his species are currently recog-
nized: L. glandulosa, L. linearis, L. pilosa (in-
cluding L. rudis), and L. suffruticosa.
Jean Baptiste A. P. M. de Lamarck (1789,
1792) published “Jussiaea brachycarpa” and
“Ludwigia hirsuta," based on materials collected
from South Carolina. These names are synonyms
of L. glandulosa and L. pilosa respectively, as
Lamarck himself suspected.
The next botanist to study North American Lud-
wigia was Andre Michaux (1803), who described
nine species of Ludwigia in his Flora Boreali-
Americana. Of these, L. microcarpa is a member
of sect. Microcarpium
In 1814, Jean L. M. Poiret correctly added the

It was not until 1821 that the species of sect.
Microcarpium were described by American bot-
anists. Of the four species in sect. Microcarpium
that Steven Elliott (1816-1821) described, Lud-
wigia alata, L. sphaerocarpa, and L. lanceolata
are currently recognized, whereas L. cylindrica
represents a synonym of L. glandulosa Walter.
Although Elliott correctly differentiated L. alata
from L. lanceolata, the striking superficial resem-
blance of the two species, especially in dried her-
barium specimens, has constantly been a source
of confusion among botanists (Long & Lakela, 1976;
i dfrey & Wooten, 1981;
Wunderlin, 1982; Clewell, 1985). The great dis-
tinctiveness of these two species in such characters
as floral morphology, pollen and seed surface fea-
tures, and chromosome numbers were only appre-
ciated recently (Peng, 1988, and this study).
In 1836, Ludwigia polycarpa, a distinctive
member of sect. Microcarpium distributed mainly
in the northcentral United States, was discovered
in Kentucky by Charles Wilkins Short and Robert
eter.
Shortly thereafter, John Torrey and Asa Gray
(1838-1840), in A Flora of North America, pro-
posed two varieties in sect. Microcarpium, i.e.,
Ludwigia cylindrica 8 brachycarpa and L. cap-
itata B pubens. The former is currently recognized
as the small-fruited, western subspecies of L. glan-
dulosa (Peng, 1986), whereas the latter represents
a natural hybrid between L. suffruticosa and L.
pilosa (Peng, 1988).
In 1845, George Engelmann and Asa Gray de-
scribed a densely pubescent variety of Ludwigia
linearis from Texas. Owing to the complex vari-
ation pattern and the many intermediate popula-
tions found in the range of this species, however,
the variety is not recognized in the present study.
Ludwigia stricta, the only Cuban endemic in

sect. Microcarpium, became known when August
Grisebach (1866) described /snardia stricta in Ca-
talogus Plantarum Cubensium. The correct com-
bination in Ludwigia was made by Francisco Adol-
fo Sauvalle (1873) in the Flora Cubana.
Alvin Wentworth Chapman added Ludwigia
curtissii (1883) and L. simpsonii (1892) to the
genus in his study of the flora of the southern
United States.
John Kunkel Small named Ludwigia simulata
in 1903, not knowing that it represented the hybrid
L. pilosa X L. lanceolata. In 1933, he grouped,
for the first time, plants of Ludwigia sect. Micro-
carpium under “Microcarpeae,” and described
from the Everglades of Florida L. spathulifolia,
which has now been merged with L. curtissii.
Burghard Helwig in 1928 published Ludwigia
cubensis from Cuba, which, however, is now con-
sidered as conspecific with L. simpsonii from Flor-
ida.
Merritt Lyndon Fernald and Ludlow Griscom
(1935) described three additional varieties for the
highly polymorphic Ludwigia sphaerocarpa, which
itself may have originated as a result of hybridiza-
tion and which now intergrades with L. pilosa
freely (Peng, 1988). These hybrids are not rec-
ognized in this paper for reasons discussed else-
where.
Paul Munz's monograph (1944, 1965) con-
tained the most comprehensive treatment of North
American Ludwigia in his time. In the 1944 paper,
he formally delimited sect. Microcarpium. His con-
cept has since been widely accepted. James Allan
Duke (1955) was the first author to indicate and
to provide examples of natural hybridization among
North American species of Ludwigia.
In the course of my biosystematic study of Lud-
wigia sect. Microcarpium, a number of atypical
specimens initially identified as L. pilosa Walter
were shown to be a new species, which I subse-
quently named L. ravenii (Peng, 1984). This rep-
resents the last named species of sect. Microcar-
pium, and makes the total number of species of
this section 14.
MORPHOLOGY
HABIT
All species in Ludwigia sect. Microcarpium are
erect perennial herbs ranging from about 15 to
100 cm tall. Leafy, usually unbranched stolons are
produced from the base of erect stems. The stolons
creep along the surface of moist ground or float
on water late in the flowering/fruiting season. Some
species, however, may also send out stolons in the
summer while they are actively flowering or even
throughout their growing season. The stolons can
be long (up to 2.5 m) and stout as in L. pilosa or
short (5-15[-20] cm) and slender as in L. micro-
carpa and L. ravenii. The stolons give rise to erect
shoots from their tips when the growing season
resumes. In L. polycarpa the stolons are normally
up to 15 cm long, and with leaves densely con-
gested at the apex of stolons, overlapping one
another and thereby protecting the apical meri-
stem. This is apparently an adaptation to the severe
winter that plants of L. polycarpa have to endure
in the northern States. In L. suffruticosa stolons
are uncommon. Instead, perennation is mainly by
thick, somewhat woody, branched rhizomes. New
shoots arise from the nodes of the rhizomes in
growing season. It may be that in drier sandy
situations, the plants persist by rhizomes, whereas
in wet situations, the plants send out stolons.
In Ludwigia curtissii and L. simpsonii, stolons
are rarely formed; the plants simply produce new
shoots, which are ascending or decumbent at first
and soon become erect from the base of the pre-
vious year's stem. They may not need to overwinter
with low-profile stolons, as they are distributed
mainly in Florida and the Caribbean Islands where
the growing season is long and the winter is not
severe.
STEMS
Stems are usually well branched in most species
of Ludwigia sect. Microcarpium. Plants of L.
suffruticosa are, however, often simple. When they .
branch, the branches are few and usually arise
from upper leaf axils beneath the compact inflo-
rescences and characteristically overtop the main
flowering/fruiting stems. Unbranched flowering
stems are seen also in some populations of L. cur-
tissii, L. linifolia, L. microcarpa, L. simpsonii,
and L. stricta. The stems of some plants of L.
microcarpa are distinctly zigzag. The stems of most
species are slightly ridged; those of L. alata and
L. microcarpa are often conspicuously ridged or
winged. Ludwigia pilosa is the only species with
nearly terete stems. The lower part of the stems
of all species, when entirely submerged, is swollen
and spongy.
PUBESCENCE
Many species in Ludwigia sect. Microcarpium
are glabrous to subglabrous; the margins of leaf,
sepal, or bracteoles, and surfaces of fruit may
sometimes be minutely strigillose or minutely pa-
pillose. Only L. ravenii and L. pilosa are consis-

Ludwigia sect. Microcarpium
tently hirtellous throughout. Ludwigia sphaero
carpa, a species that intergrades substantially with
L. pilosa, is variable in many aspects, especially
pubescence. Populations of L. sphaerocarpa range
from being completely glabrous to densely strigil-
lose throughout. Similarly variable is L. linearis,
but no interspecific hybridization has apparently
played a role here. The pattern of the distribution
of hairs in L. suffruticosa is especially interesting:
some plants are completely glabrous; some plants
are hirtellous either on the terminal inflorescence
or on the basal stems (including stolons/rhizomes),
or both, but are otherwise glabrous.
The following are the main types of pubescence:
l. Minutely puberulent. Hairs exceedingly
short, fine, straight, erect to ascending, sparse or
dense, 0.02-0.1 mm long, found occasionally in
plants of Ludwigia linearis, L. sphaerocarpa, on
fruits of L. microcarpa, and less commonly on
fruits of L. simpsonii, L. curtissit, and L. suffru-
ticosa.

cellular, 0.1—0.6 mm long, appressed to ascending;

carpa and L. linearis.
3. Minutely strigillose. Similar to strigillose
pubescence, but the hairs more slender and shorter,
ranging from 0.02 to 0.1 mm long. Frequently
seen on sepals, bracteoles, and leaves of various
species; also on the wings of capsules in Ludwigia
lanceolata and capsules of both subspecies of L.
glandulosa, and occasionally of L. polycarpa.
Blunt-tipped, minute
projections from the surface, ca. 0.02-0.03 mm
in length. This hair type is found occasionally on
the margins of leaves and sepals, on fruit walls,
and on nectary discs. It may be difficult to distin-
guish from minutely strigillose hair when the latter
is exceedingly short.
. Hirtellous. stiff, straight,
erect to spreading, with an attenuate apex and a
slightly broadened base, 0.25-0.95 mm long,
translucent or spotted with light brown pigments.
Hairs of this type are typical of Ludwigia pilosa,
L. ravenii, and occasionally of L. sphaerocarpa,
as well as part of the plant body of L. suffruticosa.

LEAVES
The leaves are simple and alternate. Ludwigia
simpsonii is exceptional in frequently having some
opposite or subopposite leaves at the lower nodes
or in the seedling stage, a feature that might be
related to the derivation of one or more of its
genomes from plants of the opposite-leaved sect.
Dantia (see below). The leaves on the rhizomes of
. suffruticosa are small and scalelike. Those on
stolons are mostly elliptic- to rhombic-obovate or
suborbicular (narrowly elliptic to narrowly oblan-
ceolate in L. linearis and L. linifolia). These are
usually broader and shorter than the cauline leaves,
which are usually narrowly lanceolate to lanceolate,
occasionally elliptic or oblanceolate, and often
gradually reduced and narrower up the stem. Lud-
wigia linearis and L. linifolia have sublinear leaves.
In L. curtissii, L. microcarpa, and L. simpsonii,
the leaves range from (narrowly) spatulate-oblan-
ceolate to spatulate-obovate or spatulate.
The leaves of all species of sect. Microcarpium
are sessile or nearly so and either narrowly cuneate
or attenuate basally. Ludwigia suffruticosa is ex-
ceptional in having a rounded to obtuse leaf base.
As in Ludwigia sect. Myrtocarpus sensu lato
(Ramamoorthy & Zardini, 1987), the leaf margin
is usually subentire, with a few glandular reddish
or pink teeth that have an unusual hydathodal
structure (Castells et al., 1979; Keating, 1982);
such teeth are especially evident in L. microcarpa.
The secondary veins of leaves are usually ob-
scure adaxially and distinct abaxially in sect. Mi-
crocarpium. In the closely allied Ludwigia lini-
folia and L. stricta and in L. simpsonii and L.
curtissii, the secondary veins are, however, faint
on both sides of the leaves. Ludwigia linearis,
having narrow leaves like the related L. linifolia,
has, by contrast, on its abaxial leaf surface very
evident secondary veins, which anastomose and
form a pair of marginal veins along the margins.
INFLORESCENCE
The flowers are sessile or shortly pedicellate and
borne singly in the (usually upper) leaf axils of the
main stem and the branches. In Ludwigia suffru-
ticosa, the flowers are congested in very compact
terminal spikes or racemes. The leaves subtending
the flowers are much reduced and bractlike. As
stems of this species remain single or have only a
few branches, there are only one to several such
inflorescences per plant. In most other species, the
stems are well branched, and the flowers are ax-
illary and usually very abundant. In L. alata and
L. pilosa, the flowers are sometimes quite con-
gested on the upper parts of branches. In L. poly-
carpa and L. glandulosa, one to a few very short
branches heavily laden with flowers/ fruits are often
seen from the very base of primary branches. This
frequently gives an appearance of several flowering
ranches arising simultaneously from the nodes of
the main stem.
226 Annals of the
Missouri Botanical Garden
PEDICELS PETALS
The flowers and fruits are nearly sessile in most
species. Pedicels (measured from the base of ma-
ture fruits), when present, are usually up to 0.5
(-1) mm long. Pedicels of Ludwigia suffruticosa
and L. sphaerocarpa range 0.5-1.5(-2.3) mm
long. Populations of L. linearis from west of the
Mississippi River often have distinct pedicels up to
3.5(-5) mm long.
BRACTEOLES
Bracteoles are present in pairs near the base of
the ovary in all species. They are succulent and
are flanked by a pair of reddish or dark purplish,
glandlike stipels on their base. A small swollen
emergence located immediately below the bracteole
is apparently an extension of the bracteole base
and is prominent in some species, especially Lud-
wigia curtissii, L. lanceolata, L. microcarpa, and
L. simpsonii. This character is more evident in
live plants than in herbarium specimens.
Despite often being variable in length, even with-
in the same plant (in Ludwigia linifolia, the brac-
teoles range (1.5-)2.5-9(-13) mm long), a few
species, including L. glandulosa, L. microcarpa,
and L. sphaerocarpa, consistently have shorter
bracteoles (less than 1.5 mm long) than those of
the other species (Table 2). The bracteoles are
located either at the base or higher up on the sides
of the capsules. In L. sphaerocarpa and occa-
sionally in L. glandulosa, L. linearis, and L. suf-
fruticosa, however, the bracteoles are found on
the short pedicels.
FLOWERS
Of the 15 taxa of sect. Microcarpium, only
three diploid species are petaliferous, although ves-
tigial petals may occasionally appear in a few flow-
ers of polyploid species (Table 2). Flowers are con-
sistently tetramerous, pentamerous flowers being
exceptional.
SEPALS
Sepals are entire, but may be minutely strigillose
along the margins in some species. Unlike plants
of sect. Myrtocarpus sensu lato (Ramamoorthy &
Zardini, 1987), the sepals persist even after the
capsules mature and dehisce. Sepals are greenish
in most species, but they are creamy white on the
adaxial surface in L. alata, L. pilosa, and L.
suffruticosa and are yellowish on the adaxial sur-
face in L. sphaerocarpa.
Petals are yellow, small, narrowly obovate to
subrotund, and range from 2.5 to 6 mm long and
from 1.2 to 5 mm wide. They fall off a few hours
after anthesis, which occurs early in the morning,
and are usually gone by noon. All petaliferous
species are able to effect mechanical self-pollina-
tion. My field experience, however, did not allow
me to judge whether these plants attract signifi-
cantly more insect pollinators than other apetalous
species with showy sepals.
STAMENS
Most species of Ludwigia are consistently either
haplostemonous (stamens in one whorl) or diploste-
monous (stamens in two whorls) (Ramamoorthy &
Zardini, 1987). All species of sect. Microcarpium
are haplostemonous, which is a derived condition.
The stamens are antesepalous, situated between
the sepal base and the nectary discs.
ANTHERS
The anthers vary from 0.1 mm long in Lud-
wigia microcarpa to 2 mm long in L. linearis.
Ludwigia linearis is unique in sect. Microcarpium
in having polysporangiate anthers partitioned hor-
izontally by septa that include both tapetum and
parenchyma (Tobe & Raven, 1986). Such spe-
cialization is shared only by L. latifolia, an un-
related South American species of sect. Tectiflora,
and five other genera of Onagreae. It is worth
noting, however, that these septa in the anthers
disintegrate and result in a continuous sporogenous
tissue before the anthers dehisce. Many conspic-
uous vestiges of the disintegrated septa are visible
on the inner surface of the anther wall at this stage.
POLLEN
The pollen of Ludwigia sect. Microcarpium is
quite uniform, being characterized by isopolar grains
frequently with prominent colpal extensions and
with a psilate exine (Praglowski et al., 1983). Five
species of sect. Microcarpium — L. alata, L. cur-
tissit, L. microcarpa, L. simpsonii, and L. suf-
fruticosa—shed their pollen singly, whereas the
other nine species shed their pollen in tetrads (Table
2). This character is of some taxonomic value. For
example, it can be used along with seed-surface
pattern to distinguish L. alata, which sheds its
pollen singly, from L. lanceolata, which sheds its
pollen as tetrads. These two species are similar in
general aspect and in their obpyramidal, winged

DISCS
One of the important characters that allows Lud-
wigia to be recognized as the sister group to all
other genera of Onagraceae is that its nectary disc
is situated on the summit of the ovary. By contrast,
all other onagraceous plants have nectaries at the
base of the floral tube; the nectaries, therefore, are
androecial (Eyde, 1981).
The discs of Ludwigia sect. Microcarpium are
shallowly dome-shaped, and they occur on the apex
of the ovary. They are more or less distinctly four-
lobed, the lobes alternating with the stamens, and
re antepetalous (in petalous species). They are
usually yellow or greenish at anthesis and turn dark
reddish purple in fruit. In most species the discs
are glabrous. Ludwigia pilosa is, however, usually
hirtellous around the style base and between the
disc lobes. Plants of L. sphaerocarpa are some-
times hirtellous between the disc lobes, too. In
densely strigillose populations of L. linearis, the
nectary discs tend to be strigillose throughout or
between the lobes also. In L. linifolia and L. stric-
ta, the disc lobes are minutely papillose throughout,
as are their fruit and seed surfaces.
CAPSULES
Characters of the capsules have been very useful
to systematic and phylogenetic studies in Ludwigia
(Small, 1933; Munz, 1942, 1944; Raven, 1963;
Eyde, 1978; Ramamoorthy & Zardini, 1987).

wigia sect. Microcarpium (as ““Microcarpeae”),
the mode of capsular dehiscence was one of the
main criteria. Although his observations on cap-
sular dehiscence were incomplete and not all species
in this group have capsules dehiscing by the sep-
aration of flaps from the Es of the nectary disc
(see below), his concept taken up by Mun
(1944, 1965) who ferially puse nd d.
lished sect. Microcarpium.
The shape, size, and pubescence of capsules are
very diverse within sect. Microcarpium (Table 2,
Figs. 1-15). Capsule shape ranges from obpyrami-
dal to subcylindric, oblong-obovate, turbinate, or
subglobose, and size ranges from 1 mm long in
Ludwigia microcarpa to 12 mm long in L. linearis
and L. linifolia. The surface vestiture ranges from
glabrous to minutely papillose, strigillose, or hir-
tellous. These characters have been extremely use-
ful for identifying species and natural hybrids.
Furthermore, in Ludwigia sect. Microcarpium,
three patterns of capsular dehiscence are recog-
nized (Peng & Tobe, 1987), each of which has a
distinct anatomical basis:
Ring dehiscence. The capsule dehisces along
an apical “ring” as a result of the disintegration
of thin-walled cells located between the nectary
disc and the sepal base (Fig. 16). This pattern is
exhibited by Ludwigia alata, L. lanceolata, L.
linearis, L. microcarpa, and L. suffruticosa. lt
was previously thought of as the only way capsules
of Ludwigia sect. Microcarpium dehisced (Small,
1933; Munz, 1944; Raven, 1963). In these plants

Ludwigia sect. Microcarpium
the zonation pattern in the capsule wall is relatively
simple, consisting of the outer, enlarged paren-
chymatous exocarp and the inner spongy endocarp.
Peeled dehiscence. The capsule dehisces by
the irregular rupture of the outer capsule wall (Fig.
17). This is exhibited by Ludwigia glandulosa, L.
linifolia, L. pilosa, L. polycarpa, L. ravenii, L.
sphaerocarpa, and L. stricta. These plants have
a spongy mesocarp and an endocarp with conspic-
uous inner hypodermis. When the seeds are dis-
persed, they often carry along many hypodermal
cells. Whether these cells are useful for the seeds
to float awaits confirmatio
Loculicidal delis The capsule dehisces
by amd lone four longitudinally lenticular
it h of the loculi (Fig. 18). Eventually
the cansada is split into four basally united parts.
This type of dehiscence is seen only in the closely
related polyploids Ludwigia curtissii and L. simp-
sonii. In these species, the zonation pattern of the
fruit wall is basically similar to that of the “ring-
dehiscent" species, except that the exocarp con
sists only of the outer epidermis and a single-celled
layer of outer hypodermis compactly aligned be-
neath. These hypodermal cells are remarkably en-
larged and radially elongate except along the me-
dian longitudinal line facing each locule, where they
are abruptly reduced or replaced by small, paren-
chyma cells. It is exactly along these four lines
that the capsules dehisce at maturity.
To summarize, the fruit wall of all species of
Ludwigia sect. Microcarpium is differentiated into
a spongy zone (endocarp in ring-dehiscent and loc-
ulicidally dehiscent species, or mesocarp in peeled-
dehiscent species) and a continuous zone. As Eyde
(1978) suggested, such differentiation undoubtedly
aids seed dispersal by reducing the effective thick-
ness and by the differential growth rate that could
result in the separation of the outer layers from
the inner. The specialized hypodermis in L. cur-
tissil and L. simpsonii appears to represent a
condition that has evolved a step beyond this point.
SEEDS
In all species of sect. Microcarpium, seeds have
a narrow raphe and are free and pluriseriate in
each locule of the capsule, with a narrow raphe.
The seeds are small, from .7 mm long,
and are cylindric, ellipsoid, reniform, or ovoid.
They are mostly yellowish, light brown, or brown
in color, although three species, Ludwigia linifo-
lia, L. microcarpa, and L. stricta, nearly always
have dark reddish seeds.
Eyde (1978) was the first to point out that
species of sect. Microcarpium are remarkably di-
verse in surface cell orientation. Like capsule mor-
phology, or rather together with capsule morphol-
ogy, seed Eu [putem 1E ae excellent
di gnosti c identifying the species and
detecting natural hybrids. The seed surface cells
are either subisodiametric or are elongate parallel
or elongate transversely to the seed length, with
minor variation on the two ends and areas near
the raphe (Figs. 19-34). Although in different pop-
ulations of both L. glandulosa and L. linearis the
seed surface cells are oriented in two different ways,
the pattern is not random. In L. glandulosa, the
cells are elongate parallel to the seed length in
subsp. glandulosa (Fig. 23) and transversely elon-
gate in the western, short-fruited subsp. brachy-
carpa (Fig. 24). Plants of L. linearis are extremely
variable in pubescence, ranging from completely
glabrous to densely strigillose. In general, seed sur-
face pattern seems to be correlated with pubes-
cence: subglabrous plants usually exhibit cells elon-
gate parallel to the seed length (Fig. 21), whereas
densely strigillose individuals generally have seed
surface cells elongate transversely to the seed length
ig.
In Ludwigia sphaerocarpa the seed surface
cells (Fig. 29) are not as regularly oriented as they
are in the other species. They are arranged in
columns both transversely elongate and parallel to
the seed length, with the former alignment often
dominant in the central part of the seed. Some

seeds of this species have variously oriented cells,
a pattern that supports the suggestion of a hybrid
origin for L.. sphaerocarpa (see below).
REPRODUCTIVE BIOLOGY
All 14 species in Ludwigia sect. Microcarpium
are genetically self-compatible perennials that re-
produce sexually and vegetatively. About two-thirds
of them are modally autogamous—a statistic com-
parable to that for the whole genus (Raven, 1979).
Shortly after the flowers open in the morning, the
stigma becomes sticky and receptive and the sta-
mens dehisce, exposing yellowish pollen entangled
by the viscin threads. Initially the stamens are held
away from the stigma and spread apart. The fila-
ments, however, gradually arch toward the center
and finally the anthers become firmly appressed to
the sides of the sticky stigma in one to several
hours (usually before noon), thus effecting self.
pollination. This occurs in petaliferous as well a
apetalous species, with the exceptions discussed in
the following paragrap
In Ludwigia alata, L. pilosa, L. suffruticosa,
and many individuals of L. sphaerocarpa, the an-
thers also bend toward the stigma at late anthesis,
but the distance between the androecium and the
gynoecium is such that self-pollination is impossible
without the intervention of a pollen vector. In the
first three, apetalous, species the sepals are con-
spicuous and creamy within; in L. pilosa they are
often tinged with pink along the main veins and
the edges. Presumably these petaloid sepals serve
to attract insect pollinators. In addition, these three
species have yellowish discs that produce abundant
nectar. Ludwigia sphaerocarpa, by contrast, has
sepals that are yellowish within and very bright
yellow discs that are more conspicuous than those
of any other species, with the possible exception
of L. linifolia (see below). Outcrossing in all four
above-mentioned species is therefore not reinforced
by protogyny/protandry or by male sterility, but
merely by the physical separation of the stigma
and the anthers. The self-incompatibility found in
the more primitive members of Ludwigia sect.
Myr tocarpus sensu lato is not present in sect.
Microcarpium
ectary discs are present in all species in sect.
Microcarpium, but they vary in size and in the
quantity of nectar produced. Ludwigia microcar-
pa. an apetalous species with tiny flowers (the
ovary is less than 1 mm long), has a nearly flat,
greenish disc that produces very little nectar, and
is presumably highly autogamous. Despite this, the
fact that several natural hybrids—e.g., L. micro-
carpa X L. curtissii and L. microcarpa X L.
simpsonii, and an intersectional hybrid, L. micro-
carpa X L. palustris (n — 8; sect. Dantia)—
were collected in the field where the parental species
grow sympatrically (see below) suggests that insect
pollinators do occasionally visit plants with minute,
inconspicuous flowers.
Living plants from two of the three petaliferous
species were available for observation; Ludwigia
stricta, endemic in Cuba, has not been studied as
a living plant. Flowers of L. linifolia have very
conspicuous nectary discs that produce copious
nectar. This, along with the yellow petals, serves
to make the flowers highly attractive to insects.
Ludwigia linearis has a comparatively shallow
ovary disc that secretes less nectar. This species
is noteworthy in sharing with the unrelated South
American L. latifolia (Benth.) Hara (sect. Tecti-
flora) the distinction of being the only members of
the genus Ludwigia in which the sporogenous tis-
sue of the anthers is divided into packets horizon-
tally by both tapetum and parenchyma (Eyde, 1977;
Tobe & Raven, 1986). This character is also shared
by five other genera of Onagraceae, as mentioned
previously.
Paper wasps of the genus Polistes have been
observed to visit flowers of species of Ludwigia
sect. Microcarpium grown in the netted experi-
mental greenhouse at the Missouri Botanical Gar-
den. In the field, more insects (usually oed
honeybees, and wasps) were attracted to L. pilo
and, less so, to L. sphaerocarpa. Moths and ants
have also been observed visiting L. pilosa. Rela-
tively few field observations of insect pollinations
on other species have been made in my trips to
the southeastern United States. Circumstantial evi-
dence from the presence of abundant natural hy-
brid populations suggests that insect pollination must
be more common than I have observed.
In addition to sexual reproduction, nearly all
species of Ludwigia sect. Microcarpium produce
sprawling stolons at the base of the erect, flowering
stems late in their flowering season. This vegetative
reproduction enables the plants to overwinter, when
the erect stems die back; in spring, they can then
produce a large colony before other species can
invade. Some of the sterile populations of natural
hybrids also persist by this means. In £. suffruti-
cosa, however, stolons are not as common as un-
derground rhizomes. In L. curtissii and L. simp-
sonii, stolons are not apparent. These plants simply
form new shoots from the lower nodes of the died-
back stem of the previous year. These shoots are
decumbent or ascending initially, but soon become
erect.

Chromosomes of Ludwigia are the smallest in
the Onagraceae, and they may differ conspicuously
in size within a single genome. The proximal ends
of the chromosomes are heavily pycnotic and ap-
pear in interphase nuclei as very distinct and def-
inite chromocenters (Kurabayashi et al., 1962).
The basic chromosome number of the genus is x
= 8, with no aneuploidy but extensive polyploidy
(Raven & Tai, 1979). Through the efforts of Greg-
ory & Klein (1960), Kurabayashi et al. (1962),
Raven & Tai (1979), and Peng (1984, 1988), the
chromosome numbers of all species of Ludwigia
sect. Microcarpium have been established. There
are four diploid species with n = 8 (L. linearis,
L. linifolia, L. microcarpa, and L. stricta), eight
tetraploid taxa with n — 16 (L. glandulosa subsp.
glandulosa, L. glandulosa subsp. brachycarpa,
L. lanceolata, L. pilosa, L. polycarpa, L. ravenii,
L. sphaerocarpa, and L. suffruticosa), two hexa-
ploid members with n — 24 (L. alata and L. simp-
sonii), and an octoploid with n — 32 (L. curtissii).
For a review and discussions see Peng (1988).
EcoLoGY AND GEOGRAPHICAL DISTRIBUTION
With the exceptions of Ludwigia stricta, which
is endemic to Cuba, and L. polycarpa, which is
distributed mainly in the northcentral United States,
Ludwigia sect. Microcarpium is confined primar-
ily to the Coastal Plain of the southeastern United
States. Several species also extend further south
or east: L. alata to Jamaica; L. curtissii to the
Bahamas; and L. linifolia disjunct to Tabasco,
Mexico. Ludwigia simpsonii occurs in Cuba and
Jamaica, and L. microcarpa in the Bahamas, Cuba,
and Jamaica. Ludwigia stricta is exceptional in
being endemic to Cuba. A detailed description of
the ranges with maps for each species is given in
the taxonomic treatment.
Like Ludwigia species occurring in other parts
of the world, plants of Ludwigia sect. Microcar-
pium grow in wet habitats. They are commonly
found along alluvial ground or in the shallow water
of many areas, including ponds, lakes,
streams, lagoons, sloughs, backwaters, swales, wet
rivers,
meadows or prairies, open swamp forests, drain-
ages, and irrigation ditches. All species grow in
sandy or occasionally peaty soils. A few species
grow in brackish marsh or tidal flats (L. alata, L.
linifolia, L. microcarpa, and L. simpsonii), in
sinks in limestone prairies (L. alata, L. curtissii,
L. microcarpa, L. simpsonii, L. sphaerocarpa,
and L. suffruticosa), and in clay soils (both sub-
species of L. glandulosa). None of the species in
Ludwigia sect. Microcarpium exhibit the aggres-
siveness characteristic of weedy plants, although
the following taxa have rarely been observed grow-
ing in disturbed habitats: L. linearis, L. micro-
carpa, L. simpsonii, and both subspecies of L.
glandulosa.
EXPERIMENTAL HYBRIDIZATION
Results from the extensive artificial hybridiza-
tion among members of Ludwigia sect. Micro-
carpium (Peng, 1988) are summarized as follows.
l. There is generally little difficulty in obtaining
hybrids between members of sect. Microcar-
pium; most F, plants grow to maturity, and
many set abundant seeds. Hybrids between
plants of the same ploidy level are generally
intermediate in morphology; hybrids between
plants of different ploidy levels tend to be more
similar to the parent with the higher chromo-
some number. Character such as capsule shape
and size, bracteole length, overall pubescence,
presence or absence of petals, seed surface pat-
tern, and pollen stainability are very useful in
distinguishing species and identifying hybrids.
. All diploid species can be crossed with one
another and form floriferous F, plants. Hybrids
N
between the petaliferous diploids with narrow
leaves (Ludwigia linearis and L. linifolia) are
vigorous, have ca. 50% stainable pollen, and
produce a moderate amount of viable seeds. A
modal meiotic configuration of a ring or chain
of four plus six bivalents are frequently ob-
served in reciprocal F, hybrids. Hybrids be-
tween either of the petaliferous diploids and the
apetalous, diploid L. microcarpa are, in con-
trast, highly sterile as to pollen and seed set.
Nearly all chromosomes remain unpaired in
meiosis in these hybrids.
. All eight tetraploid members studied are inter-
o2
fertile: chromosome pairing in meiosis is nearly
complete, and pollen stainability and seed set
are high in hybrids between any two tetraploid
species, no matter how different they are from
each other morphologically.

Ludwigia alata and L. simpsonii, can

stainable pollen. Meiosis in these F, individuals

typically exhibited a maximum of 16 bivalents
and eight unpaired chromosomes. By contrast,
the hexaploid Ludwigia simpsonii (n — 24) is
clearly allied to the octoploid L. curtissii (n —
32). Hybrids between them are highly fertile,
having 80-90% stainable pollen and producing
good seed set. These plants consistently exhib-
ited a meiotic configuration of 24 bivalents and
eight unpaired chromosomes.
Seeds obtained from crossing species of any two
of the following groups, (1) tetraploid species
group (including the allied Ludwigia alata), (2)
diploid species, and (3) L. curtissii and L. simp-
sonii, often failed to germinate. Those that ger-
minate may either be inviable or produce flow-
ers that set negligible or no seed and tend to

have very low levels of stainable pollen. For a
complete discussion of the experimental hy-
brids, consult Peng (1988).
NATURAL HYBRIDIZATION
Experimental hybridization (Peng, 1988) re-
vealed that vigorous and floriferous hybrids can
readily be obtained between most members of Lud-
wigia sect. Microcarpium. The general lack of
postzygotic barriers and the facts that all species
in this section are perennial and that most of them
are sympatric, have similar preference for habitats,
flower in the morning during the same season, are
facultatively outcrossing, and have similar kinds of
indiscriminate insect pollinators, strongly suggest
that natural hybrids should be fairly common in
the field.
Field observations and herbarium study show
that hybrid populations of Ludwigia sect. Micro-
carpium are indeed abundant. Except for this and
the companion paper (Peng, 1988), however, very
little has been reported about the natural hybrid
populations of sect. Microcarpium. The variation
patterns generated by the intergradation among
some members of sect. Microcarpium have pre-
viously been detected by Torrey & Gray (1840)
and Small (1903); such plants were given names
at varietal and specific rank respectively, but no
indication of their hybrid origins was mentioned.
Torrey & Gray (1840) described L. capitata B
pubens from a population of L. suffruticosa X L.
pilosa from Georgia; Small (1903) applied the name
L. simulata to a population of L. pilosa x L.
lanceolata from North Carolina.
Duke (1955) was the first to point out that some
Ludwigia species show varying degrees and pat-
terns of intergradation in North Carolina. In his
informative study, he compared the morphological
characters of a mixed population consisting of plants
of L. pilosa, L. glandulosa, and the intermediates,
and considered the latter as possible hybrids. Upon
examination of his voucher collections, it is con-
firmed beyond doubt that these plants represent
uniform F, hybrids of L. pilosa x L. glandulosa.
Duke (1955) further suggested that “‘self-pollina-
tion is the rule in this genus, and that cross-polli-
nation is a very rare exception to the rule," and
speculated that phyllophagous insect caterpillars
may have brought about cross-pollination while for-
aging leaves. This, however, is not true, as at least
four species in sect. Microcarpium have somewhat
showy sepals and produce copious nectar and re-
quire insect vectors to pollinate their flowers to set
seeds. Such insects as bumblebees, wasps, honey-
bees, moths, and even ants have frequently been
seen obtaining nectar on the flowers of Ludwigia
sect. Microcarpium.
In a biosystematic study of Ludwigia sect. Dan-
tia, a close ally of sect. Microcarpium with op-
posite leaves and prostrate habit, Schmidt (1967)
reported two intersectional hybrids, L. repens X
L. simpsonii (as L. repens X L. curtissii) and L.
palustris X L. glandulosa from North Carolina
and Florida, respectively. His observations of the
hybrid between L. palustris (n = 8; sect. Dantia)
and L. glandulosa (n = 16; sect. Microcarpium)
revealed very little association between chromo-
somes, with 0-3 weakly joined bivalents in meiosis.
The other natural hybrid, involving L. repens (n
— 24; sect. Dantia) and L. simpsonii (n — 24;
sect. Mesa. yielded 48 unpaired chro-
mosomes at mesiosis, suggesting the dissimilarity
in the genomes of plants in the two North American
sections.
Observation of individuals exhibiting a combi-
nation of characters intermediate between distinct
taxa initially suggests natural hybridization. Mem-
bers of the following species pairs, Ludwigia alata
(n — 24) and L. lanceolata (n = 16), L. pilosa
(n = 16) and L. ravenii (n = 16), and L. simpsonii
(n = 24) and L. curtissii (n = 32), however, are
usually so similar in appearance, especially in dried
herbarium specimens, that their hybrids cannot be
recognized readily.
esults from experimental hybridization suggest
that capsule shape and size are the most important
diagnostic characters for detecting hybrids in sect.
Microcarpium. Other useful features include over-
all pubescence, seed surface cell shape and ori-
entation, the presence or absence of petals, whether
pollen grains are shed singly vs. in tetrads, and
pollen stainability. Seed surface pattern is useful
only for the determination of hybrids in the tet-

raploid group (including Ludwigia alata), as these
nine taxa are interfertile, yield abundant seeds, and
are diverse with respect to this character. Absence
of developing fruits and low levels of pollen stain-
ability, however, are characteristic of hybrids re-
sulting from all other heteroploid crosses, with the
exception of L. curtissii (n = 32) x L. simpsonii
— 24). As a last resort, chromosome number
and meiotic chromosome behavior are useful in-
dicators of natural hybrids when the parents in-
volved have different chromosome numbers or dif-
ferentiated genomes.
The natural hybrid populations mentioned below
are discussed dnd poetas the treatment
of the species in t tion. Full citation
of these specimens of hissed is given in the com-
panion paper (Peng, 1988).
ield experience indicates that natural hybrid
populations are fairly common wherever two or
more species grow side by side. A total of 15
intrasectional hybrids and seven intersectional
(among plants of sects. Microcarpium and Dantia)
hybrids are recognized (Peng, 1988). Hybrids re-
sulting from crosses among members of the tet-
raploid species group (including Ludwigia alata)
are by far the most common. The following hybrid
combinations are representative: L. alata X L.
pilosa (four populations from Florida, one from
Georgia, and one from Mississippi), L. alata x L.
suffruticosa (seven populations from Florida), L.
glandulosa subsp. glandulosa X L. glandulosa
subsp. brachycarpa (one from Oklahoma and one
from Texas), L. glandulosa subsp. glandulosa x
L. pilosa (two from North Carolina, one from Geor-
gia, one from Alabama, and two from Mississippi),
L. glandulosa subsp. glandulosa X L. sphaero-
carpa (one from South Carolina, one from Mis-
souri), L. lanceolata X L. pilosa (three populations
from Florida), L. lanceolata x L. suffruticosa (two
from Florida), L. pilosa x L. sphaerocarpa (many
populations from North Carolina, South Carolina,
Georgia, Florida, Alabama, and Texas), L. pilosa
X L. suffruticosa (two from North Carolina, three
from Georgia, and two from Florida), and L. poly-
carpa X L. sphaerocarpa (two populations from
Indiana). Backcrossed generations or segregates of
advanced generations are found of L. lanceolata
X L. suffruticosa, L. pilosa X L. suffruticosa,
and most abundantly of L. pilosa X L. sphaero-
carpa.
As in the case of artificial hybridization, the
tetraploid hybrids are highly fertile as to seed and
pollen; hybrids between the hexaploid Ludwigia
alata and the tetraploid species have slightly lower
levels of stainable pollen and seed set. It is note-
worthy that in nearly all of the above hybrids at
least one member of p pur of putative parents
is unable to und If-pollination
has somewhat qmm sepals. In other words, L.
alata, L. pilosa, L. sphaerocarpa, and L. suffru-
ticosa hybridize more frequently than other tet-
raploid species that are modally autogamous.

16) x L. lin-
earis (n — 8) (one population from North Carolina
and the other from Georgia) and L. sphaerocarpa
(n = 16) x L. linearis (one population from Al-
abama). One probably diploid hybrid population of
L. linearis X L. linifolia was collected from Flor-
ida in 1981. Attempts to re-collect and to study
live plants of this hybrid have failed, because the
habitat was destroyed (Popenoe, pers. comm.).
Hybrids between Ludwigia curtissii (n = 32)
and L. simpsonii (n — 24) very probably occur in
the field but would be difficult to detect. Ludwigia
curtissii hybridizes with L. linifolia (n = 8) and
include Ludwigia glandulosa (n —
with L. microcarpa (n — 8) to form sterile hybrids.
At least four populations of L. simpsonii X L.
microcarpa are known from Florida. It is of in-
terest to note that among the putative parental
species here concerned, only L. linifolia has some-
what showy petals and produces copious nectar,
whereas all other species are probably modally
autogamous.
Hybrids involving putative parents from sect.
Microcarpium and sect. Dantia are also not un-
common. Ludwigia repens (n — 24; sect. Dantia)
hybridizes with L. simpsonii (n — 24) and L. cur-
tissii (n = 32) in Florida. At least eight such
populations are known, all producing flowers, but
the ovaries abort after mechanical self-pollination.
Ludwigia palustris (n = 8; sect. Dantia), a wide-
spread and apparently autogamous species, hy-
bridizes with L. glandulosa subsp. glandulosa (n
— 16) and forms sterile hybrid populations in Vir-
ginia (one population). It also hybridizes with the
diploid, small-flowered and presumably autogamous
L. microcarpa of sect. Microcarpium and forms
sterile hybrids in North Carolina (one population),
Georgia (one population), and Florida (three pop-
ulations). In Kentucky, L. palustris hybridizes with
L. polycarpa (n — 16) and likewise forms sterile
hybrids.
The only intersectional tetraploid hybrid is known
from a single population of Ludwigia arcuata (n
— 16; sect. Dantia) X L. pilosa (n — 16) collected
from Alabama. Flowers of both putative parents
are showy and attract many insect pollinators. Es-
tablished hybrids, however, are very rare in nature.

Such hybrids synthesized in the experimental
greenhouse showed a remarkably high level of
chromosome pairing (ca. 12-15 bivalents and 2-
8 unpaired univalents; 1 or 2 trivalents occasionally
seen) but had only 38% stainable pollen. Not a
single seed was set despite many attempts at ar-
tificial self-pollination (like L. pilosa, this hybrid
cannot undergo mechanical self-pollination).
o summarize, geographical isolation and self-
pollination are the primary factors limiting natural
sect. Mi-
crocarpium. For example, L. polycarpa occurs in
the central Midwest (Fig. 45), where it is isolated
geographically from all other species of sect. Mi-
crocarpium except L. sphaerocarpa. Where the
hybridization among species of Ludwigia
two species come into contact, hybridization oc-
curs. Ludwigia microcarpa, an extreme selfer,
has been hybridized successfully with most species
of sect. Microcarpium in the greenhouse, and the
resulting hybrids were vigorous. Ludwigia micro-
carpa grows sympatrically with many other species,
but natural hybrids have been found only with £.
simpsonii, L. curtissii, and some members of sect.
Dantia.
In general, natural hybrids are usually frequent
wherever two species occur together. This is par-
ticularly true for plants in the tetraploid group,
hybrids of which were often found intermixed with
utative parents. The sorts of disturbed habitats
suggested by Anderson (1948) do not appear to
be necessary for the establishment of natural hy-
rids in Ludwigia sect. Microcarpium
As outlined above, natural hybridization is not
limited to species within Ludwigia sect. Micro-
carpium. At least seven hybrid combinations, some
of which occur commonly in nature, have been
found between members of sect. Microcarpium
and sect. Dantia. Most of these have also been
synthesized in the experimental greenhouse. None

of the intersectional hybrids set viable seeds, al-
though they are usually very vigorous and appear
to compete well with their parents. Once estab-
lished, these sterile hybrids may be able to persist
in a given location due to their perennial habit.
Furthermore, new colonies may be established veg-
etatively if entire plants or fragments are trans-
ported to suitable habitats, most likely by water.
EVOLUTIONARY RELATIONSHIPS
Ludwigia sect. Microcarpium consists of four
diploids, eight tetraploids, two hexaploids, and one
octoploid.
Ludwigia microcarpa is distinct among the di
loid species by the more or less spatulate cauline
leaves and small, inconspicuous, apetalous flowers;
and it is modally self-pollinated. All three other
diploid species, L. linearis, L. linifolius, and
stricta, have elongate, narrow leaves and relatively
showy, petaliferous flowers and are facultatively
outcrossing. The divergence of L. microcarpa from
the rest of the diploids is further demonstrated by
the cytogenetic study of artificial hybrids in this
group. Artificial F, hybrids between L. microcarpa
and either L. linearis or L. linifolia were com
pletely sterile; in meiosis they revealed very few
chromosome associations, with 0-3 weakly joined
bivalents.
Ludwigia linearis is unusual in sharing with the
unrelated South American species L. latifolia
(Benth.) Hara (sect. Tectiflora) the character of
polysporangiate anthers in which the locules are
divided by transverse septa composed of tapetum
and parenchyma. Otherwise, L. linearis is appar-
ently somewhat related to L. linifolia. The two
species differ chromosomally by at least one recip-
rocal translocation. F, hybrids between them have
ca. 50% stainable pollen, and they produce mod-
erate quantities of viable seeds.
Ludwigia stricta, which is endemic to Cuba, is
more closely related to L. linifolia than to any
other species in sect. Microcarpium. It differs from
L. linifolia only by the broader leaves, smaller
floral parts, and shorter fruits (Table 3). The cross-
ing relationships of L. stricta with other diploid
species are currently being investigated.
The eight tetraploid taxa (n — 16) are uniformly
apetalous and are otherwise remarkably diverse in
overall pubescence, shape and color of sepals, shape
and dehiscence of capsules, bracteole length, seed
surface cell pattern, and whether pollen is shed
singly or as tetrads. Correlations in these features,
however, are evidently nonexistent. It is therefore
of great interest to find that these eight morpho-
logically well-delimited taxa can be crossed in any
combination and produce vigorous and fertile off-
spring. The hybrids exhibit nearly complete chro-
mosome pairing and high levels of stainable pollen.
Natural hybridization among plants of this group
is abundant, especially among those members with
somewhat showy sepals. Most natural hybrids are
F, plants that occur in more or less undisturbed
habitats where the putative parents also grow. In-
trogressed populations or segregates of advanced
generation of Ludwigia pilosa X L. sphaerocarpa
hybrids, however, are also abundant and wide-
spread. Cytogenetic studies of experimental hybrids
between the tetraploid species and the diploid species
suggest that no extant diploids are believed to have
been involved piani in the formation of the tet-
e species grou
udwigia alata, a piba (n = 24) species,
fet the tetraploids morphologically. Super-
ficially it is most similar to L. lanceolata in general
aspect and especially in the characters of winged
capsules. Nearly all of the reciprocal hybrids be-
tween the hexaploid L. alata and any of the tet-
raploid species exhibited a modal meiotic config-
uration of 16 bivalents and 8 univalents, which
suggests that they share two genomes in common.
Judged from the morphology of the hexaploid and
from the pairing of chromosomes in experimental
hybrids, L. alata probably originated following hy-
bridization between one of the tetraploids, perhaps
L. lanceolata, and the diploid L. microcarpa, or
populations ancestral to them.
The affinity of the other hexaploid, Ludwigia
simpsonii, however, is definitely with L. curtissit,
the only octoploid in sect. Microc | wid These
two species are unique in having
and in having, along with the diploid L. microcar-
a, more or less spatulate cauline leaves. Ludwigia
curtissii and L. simpsonii are polymorphic and
are sometimes difficult to distinguish morphologi-
cally. Cytogenetic data suggest that the hexaploid
chromosome complement of L. simpsonii includes
three different genomes, one of which is identical
with that of L. microcarpa. Artificial hybrids be-
tween L. simpsonii and L. curtissii exhibited a
meiotic configuration of 24 bivalents and eight
univalents, which suggests that these two closely
related species possess three genomes in common.
Based on morphological characters and crossing
relationships, the octoploid L. curtissii was prob-
ably derived following hybridization between a pe-
taliferous, narrow-leaved diploid lineage similar to
L. linifolia and the hexaploid L. simpsonil.
o summarize, following the differentiation of
diploid species of Ludwigia sect. Microcarpium,
some diploids have evidently become extinct. Nat-
ural hybridization among the diploid lineages fol-

lowed by polyploidy has played a major role in the
evolution of this group. Postzygotic genetic barriers
do not separate most of the species of this section.
Rather, the major limiting factor to natural hy-
bridization appears to be the modally autogamous
breeding system of most species. Geographical iso-
lation is important only with respect to L. poly-
carpa, which is distributed well to the north of
nearly all the other taxa.
Natural hybridization is prevalent within Lud-
wigia sect. Microcarpium, and hybrids often grow
intermixed with putative parental populations. All
interploid hybrids are completely sterile except for
alata (n — 24) and the tetra-
ploid species (n = 16), and crosses between L.
curtissii (n = 32) and L. simpsonii (n = 24). Even
sterile hybrids, however, can persist and form large
colonies, at least locally, by means of strong veg-
etative reproduction via stolons.
Natural hybrids are especially common among
members of the tetraploid group (including Lud-
wigia alata) and are nearly always vigorous and
fertile. Especially complex is the pattern of vari-
ation in the tetraploid L. sphaerocarpa, which is
apparently comprised largely of widespread stabi-
lized hybrid populations that exhibit a combination
of characters distinguishing them from other taxa.
As in the evolution of Epilobium in New Zealand
(Raven & Raven, 1976), the recombination of
genetic information from somewhat differentiated
crosses between L.
populations followed by the maintenance of well
adapted genetic strains by a combination of autog-
amy and vegetative reproduction appears to have
played a central role in the evolution of the poly-
ploid members of Ludwigia sect. Microcarpium.

As in Figures 1-15 and 19-34, the sequence
of the taxa in the taxonomic treatment reflects the
possible phylogeny of Ludwigia sect. Microcar-
pium. Diploid petaliferous species that are presum-
ably more primitively outcrossing are arranged first,
followed by tetraploid members and the related
hexaploid L. alata. Ludwigia microcarpa, an
apetalous diploid, which definitely played a role in
the formation of the distinct L. curtissii complex,
is placed last along with the complex.

Distribution. Plants of L. linifolia are often
found in drainage ditches, along margins of creeks
or swamps, on bottom meadow, on open edges of
cypress swamps, in moist pineland, and along edges
of brackish lakes. Ludwigia linifolia ranges along
the Atlantic coast from extreme southeastern North
Carolina and eastern South Carolina through south-
ern Georgia and peninsular Florida. To the west,
its range extends through the Florida panhandle,
to extreme southern Alabama and Mississippi. A
disjunct population has been collected in north-
central North Carolina (Fig. 36). It is also known
from a disjunct population at Huimanguillo, Ta-
basco, Mexico, on the Yucatán PORE. Flow-
ering from late June through October; fruiting from
July through November.

Ludwigia linifolia is a relatively uniform species.
Its variability chiefly affects the size of the capsules
and the lengths of the bracteoles, which are at-
tached to the sides of the capsule. Its closest affinity
is definitely with L. stricta, a Cuban endemic, from
which L. linifolia differs by having narrower leaves,
larger floral parts (including sepals, anthers, fila-
ments, and style), and longer fruits and bracteoles.
Characters of the two species and the only other
petaliferous member of the section, L. linearis, are
listed for comparison in Table
Ludwigia linifolia has somewhat showy petals
and the most prominent nectary disc lobes occur-
ring in sect. Microcarpium. The nectary disc is
bright yellow and produces copious nectar at an-
thesis. Herbarium specimens often reveal empt
anthers held away from the stigma (mechanical
self-pollination has not occurred yet). This obser-
vation suggests that L. linifolia is probably modally
outcrossing, which is corroborated by limited field
observations.
Ludwigia linifolia occurs with L. alata, L. cur-
tissii, L. glandulosa, L. linearis, L. microcarpa,
and L. pilosa in the field. Natural hybrid popu-
lations have, however, been found only between L.
linifolia (n = 8) and L. i
is contrary to what one would expect for the out-
curtissii (n = 32). This
crossing L. linifolia. However, experimental hy-
bridizations (Peng, 1988) indicate that artificial
hybrids between the diploid L. linifolia and plants
of any other ploidy level in sect. Microcarpium
are generally difficult to obtain. Repeated trials with
different parental strains were successful in some
cases, but the resulting hybrids were usually weak
and needed special attention to reach flowering
stage. Attempts to synthesize the natural hybrid L.
linifolia X L. curtissii in the experimental green-
house were unsuccessful.

Ludwigia stricta has a close affinity with L.
linifolia, which is distributed in the southeastern
United States and occurs on the Yucatán Peninsula
in Tabasco, Mexico. Both are diploids; they are
similar in stature, have four petals, shed their pollen
as tight tetrads, have subcylindric capsules that
dehisce irregularly from the sides, and have reddish
brown seeds with subisodiametric surface cells. A
comparison of these two species and the other
petaliferous diploid species, L. linearis, is pre-

Distribution. Ludwigia linearis is common
in drainage ditches, along river or stream banks,
swales, edges of pocosins, sandy soil in wet mead-
ows, brackish marshes, and occasionally on dis-
turbed ground. It is distributed along the Atlantic
coast from southern New Jersey through Delaware,
the eastern halves of North and South Carolina,
southern Georgia, to its southern limit in central
Florida. Westwards, this species extends through
the panhandle of Florida and across Alabama,
southern Mississippi, and Louisiana, to the central
Gulf coast of Texas. To the north, L. linearis
ranges through eastern Texas and across ron E
Arkansas, and there is a northward
from northern Alabama into Tennessee (Fi ig. 40).

The variation pattern of Ludwigia linearis is
highly complicated as a result of a great deal of
intergradation among slightly differentiated geo-
graphical races. I have classified the varied pop-
ulations into four categories: 1) the subglabrous
morph, 2) the densely strigillose morph, 3) the
completely glabrous morph, and 4) the interme-
diate morph, which is discussed below.
1. Subglabrous morph. Stems sparingly mi-
nutely strigillose. Cauline leaves glabrous except
for the minutely strigillose margin. Sepals 2.3-4
(-4.5) mm long, 1.3-2.4(-3) mm wide, the apex
acuminate, minutely scaly strigillose abaxially. An-
thers 1.1- ong, the filaments 1.3-1.8
(-2.1) mm long. Nectary disc minutely scaly strig-
illose around margins of the lobes. Style (0.4—)0.7—
0.9(-1.2) mm long, glabrous. Stigma (0.6-)1-1.5
mm long. Capsules densely minutely scaly strigil-
lose, 5-8.5(-10) mm long, 2-4(-5) mm thick,
sessile or with a constricted, pedicel-like base. Brac-
teoles 0.4-1.6(-2.5) mm long. Seed surface cells
columnar, elongate parallel to the seed length.
The type of Ludwigia linearis Walter belongs
to this morph. Plants of this sort are distributed
along the Atlantic coast from southern New Jersey
through Delaware, eastern Maryland, eastern Vir-
ginia, eastern halves of North Carolina and South
Carolina, and Georgia, to their southern limit in
the central Florida peninsula. They extend west-
ward through the panhandle of Florida and across
Alabama and southern Mississippi, reaching east-
ern Louisiana (Washington and St. Tammany par-
ishes only). Northward, they occur throughout the
eastern half of Alabama and extend to central
Tennessee.
Stems and
leaves densely minutely strigillose to puberulent in
some cases. Sepals 3-5 mm long, 1.5-2.5(-3.5)
mm wide, the apex cuspidate or elongate-acumi-
nate, minutely strigillose or puberulent abaxially.
Anthers (1.1-)1.3-2 mm long, the filaments
(1.2-)1.5-2(-2.2) mm long. Nectary disc minutely
scaly strigillose throughout or only surrounding
margins of the lobes. Style (0.6-)0.9—1.5 mm long,
glabrous to densely strigillose, especially on the
lower part. Stigma (1-)1.3-1.9 mm long. Capsules
densely minutely strigillose or puberulent, 5-10
(-12) mm long, 3-5.5 mm thick, the base sessile
2. Densely strigillose morph.
Volume 76, Number 1
1989
Peng 251
Ludwigia sect. Microcarpium
or with distinct pedicels up to 5 mm long. Brac-
teoles 0. .5) mm long. Seed surface cells
columnar, pane transversely to the seed length.
Plants of this morph were recognized at varietal
rank, Ludwigia linearis var. puberula, by
gelmann & Gray (1845). They occur most fre-
quently in central and southern Arkansas, western
Louisiana, and the eastern half of Texas. Scattered
populations, however, occur east of the Mississippi
River in eastern Louisiana and southern Mississip-
pi. A single population was found in Dallas County
in southcentral Alabama.
In addition to being much more pubescent than
plants of the subglabrous morph, plants of the
densely strigillose morph are slightly larger in the
size of most floral parts. Furthermore, their seed
surface cell pattern is different from that of the
subglabrous morph. The cells are elongate parallel
to the seed length in the subglabrous morph but
are elongate transversely to the seed length in the
densely strigillose morph.
3. Completely glabrous morph. Characters
of this morph are exactly the same as those of the
densely strigillose morph, except that the former
is glabrous throughout. Indeed, many plants of the
completely glabrous morph were collected along
with those of the densely strigillose morph. Ex-
amples are as follows:
U.S.A. ARKANSAS: Prairie Co., low moist areas in rice
paddies, P. O. Hazen, Demaree 37904 e AL gla-
brous morph: TEX, VDB-22422, VDB-4 5; mixed
collection of both the completely glabrous xe and the
densely strigillose morph: e 3
t
“of completely glabrous morph
and the densely erige morph: CAS). LOUISIANA: Bos-
sier Parish, 10 mi. S of Plain Dealing, fire lane in young
pine-hardwood stand, sandy loam, Shinners 24488 (com-
pletely clips orph: NO; densely strigillose morph:
SMU). TEXas: Waller Co., ditches, Hempstead, Hall 221
(completely aa morph: GH, MO; densely strigillose
orph: NY; mixed collection: F, NY — 2 sheets, US).
In these cases floral and vegetative characters
and even the seed surface pattern are exactly the
same in the completely glabrous and the densely
strigillose individuals. Plants of these two morphs
y well differ only by a single allele that controls
ub. expression of pubescence in plants. It is also
worth noting that plants of the completely glabrous
morph are only found scattered in Arkansas, Lou-
isiana, and Texas, the main distribution range of
the densely strigillose populations. Plants of the
completely glabrous morph were previously in-
d by Munz (1944, 1965) as a part of the
population of the subglabrous morph (as Ludwigia
linearis var. linearis), which is certainly not ap-
propriate, as discussed above.
imilarly, completely glabrous individuals that
are we single-allele mutants in populations
consisting mainly of densely pubescent plants but
are otherwise similar morphologically occur in Lud-
wigia hirtella Raf. (sect. Ludwigia; Peng, un-
published).
4. Intermediate morph. Any plant that is
more pubescent than those of the subglabrous morph
and less pubescent than the densely strigillose morph
is considered “intermediate” here. The pubescence
ranges from scattered minutely strigillose on abax-
ial midvein and/or submarginal veins to sparingly
strigillose on both surfaces of the leaves. The cap-
sule wall is minutely strigillose and not scaly strig-
illose. Floral characters generally fall in the in-
termediate range of the subglabrous and the densely
strigillose morphs. The seed surface cells, mostly
elongate transversely to the seed length, are similar
to those of the densely strigillose morph. In some
ses, however, the seed surface does not have
sell. defined cells and is difficult to study. At other
times, it is clearly intermediate between that of the
subglabrous and the densely strigillose morphs.
Plants of the intermediate morph are widely
scattered throughout the range of both the subgla-
brous morph and the densely strigillose /complete-
ly glabrous morphs. They are found in two counties
in coastal North Carolina, very well represented in
the Coastal Plain of South Carolina, scattered in a
few counties in Georgia, Florida, and Alabama, and
abundant in Mississippi, where the subglabrous and
densely strigillose morphs meet. West of the Mis-
sissippi River, they are also found as scattered
populations in Arkansas, Louisiana, and Texas, the
main distribution range of the densely strigillose
morph.
Plants designated as intermediate morph" here
represent an artificial assemblage of plants of Lud-
wigia linearis that may have originated from var-
ious combinations of somewhat differentiated pop-
ulations. For example, the intermediate plants east
of the Mississippi River often co-occur with subgla-
brous plants and may represent hybrids and their
derivatives between plants of the subglabrous and
of the densely strigillose morphs. On the other
hand, intermediate plants that grow west of the
Mississippi River may represent hybrids and their
derivatives between the completely glabrous morph
and the densely strigillose morph, as suggested by
the following mixed collections:

Plants of the subglabrous populations are some-
what distinguishable from the densely strigillose
plants (Table 4) and are separable geographically
(the boundary is roughly along the Mississippi Riv-
er). Engelmann & Gray (1845) formally recognized
the distinctiveness of the two morphs. However,
with the abundant intergradation between the two
races of L. linearis, as already noted by Engelmann
& Gray (1845), “*... these characters (of L. lin-
earis var. puberula) pd shading away into
the ordinary L. linear a as the
occurrence of the ddr i ious populations
that have further complicated the character com-
binations of L. linearis, I think a discussion of the
variation pattern within this species is more useful
than recognizing infraspecific taxa.
Ludwigia linearis was reported as naturalized
in marshy areas of Japan (Asai, 1970), and this
report was taken up by Osada (1976) in his illus-
trations of the naturalized plants of Japan. How-
ever, an examination of Asai’s voucher specimen
at TI (Japan: Honshu, Mie Pref., Suzuka-shi, Asa-
higaoka-machi (Shirako-machi), October 9, 1966,
H. Ohta s.n.) revealed that it actually represents
L. perennis L. (sect. Caryophylloidea), which is
widely distributed in the tropics and subtropics of
the Old World and ranges north to Taiwan and
southeastern China (Raven, 1963).
wigia linearis can readily be recognized by
its sublinear leaves, four yellow petals, and elon-
gate-obpyramidal capsules with a shallow, central,
longitudinal groove on each side. The only other
species in sect. Microcarpium with which L. lin-
earis might be confused is L. linifolia, which also
occurs in the Coastal Plain and the Florida pen-
insula, but much less commonly. These two species
are similar in having very narrow leaves, petalifer-
ous flowers, and elongate capsules. My biosyste-
matic study (Peng, 1988) has shown that they
differ by at least a reciprocal translocation. A com-
parison of morphological characteristics in these
two related species and L. stricta, which is endemic
to Cuba, is petaliferous, and has elongate capsules,
is summarized in Table
Ludwigia linearis and the unrelated Latin
American congener L. latifolia are unique in the
genus in having conspicuous, transverse paren-
chymatous septa in the anthers, which divide the
sporogenous tissue into packets (Eyde, 1977; Tobe
& Raven, 1986). Before the dehiscence of the
anther, however, all of these packets fuse and form
one continuous area of sporogenous tissue as a
result of disintegration of the septa, leaving the
conspicuous vestiges of the distintegrated septa on
the inner surface of the anther wall (Tobe & Raven,
1986).
Ludwigia linearis is facultatively outcrossing,
having four stamens held away from the stigma at
early anthesis and arched over, tightly appressed
against the unique, elongate stigma a few hours
after anthesis.
Ludwigia linearis is usually very floriferous and
has the highest seed set per capsule in sect. Mi-
crocarpium, about 600 seeds per mature capsule.
Ludwigia linearis co-occurs with L. glandu-
losa, L. lanceolata, L. linifolia, L. microcarpa,
L. pilosa, L. sphaerocarpa, and L. suffruticosa
in the field. Confirmed natural hybrids include L.
linearis X L. glandulosa (two collections) and L.
linearis X L. sphaerocarpa (one collection). In
both cases, hybrids are triploid, fertility as to seed
and pollen is nearly zero. Ovaries turn yellowish

a sp. glandulosa
Capsules 2-4 mm long; seed surface calls elongate
transversely to seed length ... b. subsp. brachycarpa
The two entities here regarded as subspecies of
Ludwigia glandulosa were first recognized as dis-
tinct by Torrey & Gray (1838-1840). Ludwigia
glandulosa subsp. brachycarpa differs from subsp.
glandulosa in its smaller stature, narrower leaves,
and smaller flowers and capsules. Furthermore, the
seed surface pattern of these two entities—a fea-
ture that is often diagnostic in Ludwigia sect.
Microcarpium —is sharply distinct, as given in the
ey.
Ludwigia glandulosa subsp. glandulosa is very
common and widespread throughout the Atlantic
and Gulf coastal plains and the Mississippi Em-
bayment, westward to eastern Texas and south-
eastern Oklahoma. Subspecies brachycarpa ranges
just on the western edge of that of the subsp.
glandulosa in northern Texas and Oklahoma. It
grows in the same area as subsp. glandulosa
throughout much of its range but extends farther
south and west. The general distinctiveness of these
two subspecies, without doubt, is maintained by
their modal autogamy; vegetative reproduction by
means of stolons may likewise play a role in pre-
serving favored genotypes.

Distribution. Plants of L. glandulosa subsp.
glandulosa are commonly found in roadside ditch-
es, marshes, pond borders, wet meadows, swales,
alluvial floodplains, peaty bogs, moist pinelands,
swampy woodlands, and occasionally on waste
ground. Ludwigia glandulosa subsp. glandulosa
occurs throughout the Coastal Plain from extreme
southeastern Virginia southward through eastern
North Carolina, South Carolina, south and central
Georgia to the panhandle of Florida and westward
across southern Alabama, Mississippi, and Louisi-
ana, reaching its western limit in eastern Texas.
To the north, this subspecies extends through ex-
treme southeastern Oklahoma, south and central
Arkansas, and up the lower Mississippi basin to
southeastern Missouri, central and eastern Ten-
nessee, extreme western Kentucky, southernmost
Illinois, and southwestern Indiana. Disjunct pop-
ulations of L. glandulosa subsp. glandulosa are
found in northcentral Missouri (Fig. 43). Flowering
from June to September; fruiting from June to
October.

Ludwigia glandulosa is distinctive in being the
only tetraploid species in sect. Microcarpium with
cylindric capsules. The other three species with
elongate capsules are the diploid, petaliferous, nar-
row-leaved L. linearis, L. linifolia, and L. stricta.
Raven & Tai (1979) suggested that L. linearis is
similar to L. glandulosa and might be directly
related to it. The biosystematic study of Peng
(1988), however, demonstrated that the genetic
relationship between the diploid L. linearis and the
tetraploid L. glandulosa is not any closer than that
between L. linearis and other tetraploids. Fur-
thermore, it has been shown that no extant diploids
are involved directly in the formation of any tet-
raploid species in sect. Microcarpium.
Ludwigia glandulosa subsp. glandulosa is
known to occur together with subsp. brachycarpa,
L. linearis, L. linifolia, L. microcarpa, L. pilosa,
|. sphaerocarpa, and L. palustris (sect. Dantia)
in the field. It has been known to form natural
hybrids with all but L. microcarpa, an extreme
selfer, and the facultatively outcrossing £. linifolia.
Attempts to synthesize L. glandulosa X L. lini-
folia in the experimental greenhouse also failed
~
Peng, 1988), presumably owing to incompatible
genomes. Artificial hybrids between L. glandulosa
subsp. glandulosa and L. microcarpa, however,
were healthy and floriferous.
Duke (1955) was the first to record a natural
hybrid population of Ludwigia glandulosa subsp.
glandulosa x L. pilosa, although he did not fully
describe the situation he observed. Tetraploid hy-
brids like this and others are usually fertile and are
intermediate in such diagnostic characters as ves-
titure, sepal and bracteole length, capsule shape
and size, seed surface pattern, and whether pollen
is shed singly or as tetrads. Triploid natural hybrids
involving L. glandulosa subsp. glandulosa and
diploids like L. linearis and L. palustris may be
floriferous but are highly sterile as to pollen and
seeds. Their ovaries turn yellowish or pink and
dehisce early. Ludwigia glandulosa subsp. glan-
dulosa (stems erect, leaves alternate) X L. palus-
tris (stems prostrate, leaves opposite) generally re-
sembles L. glandulosa subsp. glandulosa but has
slightly broader leaves and smaller flowers. The
stems are erect and then prostrate and erect again
in some cases; the leaves are alternate like L.

glandulosa subsp. glandulosa. By contrast, hy-
brids of L. glandulosa subsp. glandulosa and L.
linearis are similar to L. linearis, having some
yellow petals and narrow leaves. The number of
petals on each flower varies from 0 to 4.

subsp. brachycarpa are usually found along ditch-
es, in low meadows, coastal prairies, seeps in sandy
woods, moist sinkholes in granites, and old clay
fields. This subspecies occurs along the Gulf coast,
from extreme southwestern Louisiana to Nueces
County, Texas, and northward through eastern
Texas to southcentral Oklahoma (Fig. ow-
ering and fruiting from April to November.

Contrary to all other species in sect. Microcar-
pium, L. polycarpa is centered primarily in the
central Midwest, ranging from southcentral Mis-
souri, eastern Kansas, eastern and northeastern
Nebraska, northward and eastward across Iowa and
southern Minnesota into central Wisconsin and the
Upper Peninsula of Michigan. In the east, this
species occurs in extreme southern Ontario and
the eastern part of the Lower Peninsula of Mich-
igan. Ludwigia polycarpa extends southward
through western and southern Ohio, northcentral
Kentucky, and western West Virginia. Scattered
populations occur in central Virginia, southcentral
Pennsylvania, Massachusetts, and Connecticut. A
highly disjunct, presumably introduced population
has been recorded from Kootenai County, Idaho
(Fig. 45). Flowering from June to September; fruit-
ing from July to October.

Ludwigia polycarpa is the only species in sect. -
Microcarpium that occurs consistently north of
37°N, in the central Midwest of the United States.
The report of Kral (1976) on the range extension
f L. polycarpa to Covington Co., Alabama (Kral
40992, FLAS, GH, MO, NCU, NY, US, USF,
VDB), was based on a pure F, stand of natural
hybrids between L. pilosa and L. glandulosa.
Ludwigia polycarpa is therefore effectively iso-
lated geographically from all other species in the
same section except L. sphaerocarpa, which has
ide distribution throughout the Atlantic and Gulf
coastal plains, also with scattered populations in
the northeastern states as well as around the south-
ern border of Lake Michigan (Fig. 45). Indeed,
natural hybridization takes place where geograph-
ical isolation is not maintained, as is evidenced by
the presence of fertile hybrid populations of L.
polycarpa X L. sphaerocarpa found in Starke
Co., Indiana (Peng, 1988). Furthermore, sterile,
intersectional hybrids between L. polycarpa and
the prostrate, opposite-leaved L. palustris (sect.
Dantia), which is very widespread throughout the
eastern half of the United States, are found in
Ballard Co., Kentucky, the southern border of the
range of L. polycarpa (Peng, 1988)
Herbarium specimens of Ludwigia polycarpa
are rarely misidentified due partly to its geograph-
ical isolation and partly to its distinctive morphol-
ogy. Plants of L. polycarpa are generally uniform
and are characterized by having densely minutely
papillose-serrulate leaf margins, elongate-acumin-
ate sepals with reflexed tips, long bracteoles (3.5—
6.5(-8) mm) attached above the capsule base, and
the oblong-obovoid capsules that frequently exhibit
reticulate markings along the rounded corners.
Plants of Ludwigia polycarpa produce stolons

Ludwigia sect. Microcarpium
from their lower nodes in late flowering season,
like other species do. Their stolons, however, are
much shorter, normally up to 15 cm, and their
leaves, unlike those of any other species of sect.
Microcarpium, are often densely congested and
overlap at the apex of the sparsely leaved stolons.
The modified stolon is comparable to the peren-
nating turion of Epilobium (Keating et al., 1982),
which apparently serves as an adaptation to the
severe winter that plants of L. polycarpa have to
endure in the northern states.
The short stolons are occasionally found growing
from the nodes of aerial stems that have fallen to
the ground. Such specimens include:

Ludwigia suffruticosa is a very distinct species
that has many features unique within sect. Micro-
carpium. Its leaves are rounded to obtuse at the
base and clearly sessile. It has a very compact,
racemose inflorescence at the very top of each
erect stem, as is suggested by the name “Ludwigia
capitata," an illegitimate synonym of L. suffru-
ticosa Walter, coined by Michaux (1803). The
stems are usually single or occasionally with one
or two or more branches arising directly beneath
the main inflorescence. These branches always rise
above the main inflorescence and are each ter-
minated by a smaller compact raceme. Further-
more, each flower is usually subtended by a re-
duced, bractlike leaf in addition to the bracteoles
that flank the ovary. It is also the only species in
sect. Microcarpium that perennates mainly by un-
derground rhizomes. Stolons that float or send roots
into mud, prevalent in many other species, are not
common in L. suffruticosa. It is especially peculiar
in having variously pubescent inflorescences and
lower stems, stolons, and underground rhizomes
but is otherwise completely glabrous in the mid-
dle—see below.
The flowers of this species are characteristically
very compactly arranged into a raceme up to 5
cm long. The following specimens examined, how-
ever, have less compact and longer inflorescences
but are otherwise typical of Ludwigia suffruticosa:

The distribution pattern of pubescence in plants
of Ludwigia suffruticosa is peculiar and variable.
The plants range from being completely glabrous
to densely, minutely hirtellous with multicellular
hairs up to 0.6(—0.8) mm long on rhizomes, stolons,
stolon leaves, stem base, and basal leaves of the
lower plant body and peduncles, pedicels, flower-
subtending leaves, and bracteoles of the upper part
but are completely glabrous in the middle part of
the plant body. The capsules are usually completely
glabrous. In the following specimens, however, erect,
microscopic protuberances ca. 0.02-0.1 mm long
are found evenly but not densely distributed on the
fruit wall:

In a specimen collected from Florida (Leon Co.,
4 mi. S of Tallahassee, on Rt. 369, 1950, Sargent
s.n. (GA)) the capsule wall is minutely pilose with
hairs ca. 0.4 mm long.
The sepals of Ludwigia suffruticosa are nor-
mally glabrous, but in the following specimen the
sepals are minutely pilose:
U.S.A. FLORIDA: Duval Co., vicinity of Mayport &
Jacksonville, 1870-1876, Keeler s.n. (NY).
Ludwigia suffruticosa, L. alata, L. pilosa, and
L. sphaerocarpa are the species in sect. Micro-
carpium that do not undergo mechanical self-pol-
lination. With its whitish creamy sepals, which are
very showy in the dense flower aggregates, the
cross-pollinating L. suffruticosa successfully at-
tracts many insects, mostly bumblebees, honey-
bees, and wasps. It occurs with at least four species
of Ludwigia (L. alata, L. linearis, L. lanceolata,
and L. pilosa) in the field, hybridizing with all but
L. linearis. These results are mirrored in the bio-
systematic study (Peng, 1988): artificial hybrids
between L. linearis and L. suffruticosa are weak
and inviable, whereas the other combinations that
occur in nature have been synthesized successfully
and were very vigorous in the experimental green-
house.
Remarks on natural hybrids between Ludwigia
suffruticosa and either L. alata or L. lanceolata
are provided in the accounts of L. alata and L.
lanceolata. Natural hybrid populations of L. suf-
fruticosa X L. pilosa have previously been given
a varietal status within L. suffruticosa (as L. cap-
itata Michaux 8 pubens) by Torrey & Gray (1840),
which was subsequently and incorrectly considered
to be a synonym of L. pilosa by Munz (1944,
1965). The hybrids are densely hirtellous through-
out, but the hairs are not as long as those of L.
pilosa, and the sepals are neither cuspidate nor
elongate-acuminate, but rather acuminate. Fur-
ther, their stems are not well branched, their leaves
are often long and narrow, their flowers are in
more or less congested racemes on the upper part
of the stem or branch, and the leaves that subtend
their flowers are slightly reduced and bractlike.
The combination of these characteristics clearly
suggests that such plants represent hybrid popu-
lations of L. suffruticosa X L. pilosa. The possi-
bility that L. ravenii, the only species other than
L. pilosa that is consistently densely hirtellous, was
involved in their parentage is reduced because it
is rare and not known to occur with L. suffruticosa.
Furthermore, the seed surface of the hybrid plants
consists of subisodiametric cells, a characteristic of
both L. suffruticosa and L. pilosa, but not of L.
ravenii.

Ludwigia lanceolata is interfertile with all sev-
en other tetraploid members of sect. Microcar-
pium. However, it is most similar to the hexaploid
L. alata in general aspects and fruit morphology,
and is suspected to have been one of the parents
of that species (Peng, 1988). For a detailed dis-
cussion of these two species, see remarks under L.
alata and Table 5.
Ludwigia lanceolata has been found growing
with L. pilosa, L. suffruticosa, both tetraploids,
and with the diploid L. linearis. Ludwigia alata
and L. lanceolata have not been found growing
together, although they have overlapping ranges
in the eastern and central Florida panhandle. It is
worth noting that, although both species occur in
generalized, wet habitats, such as the borders of
itches, ponds, and swamps, L. lanceolata, unlike
L. alata, is not found in the limestone prairies and
brackish marshes that prevail in the Everglades
region of southern Florida. No hybrids have been
observed, but they would be very difficult to detect
without measuring pollen stainability or determin-
ing chromosome numbers.
Ludwigia lanceolata intergrades with L. pilo-
sa, and fertile hybrids between them are frequent
in nature. Such hybrids were named L. simulata
by Small (1903). The type at NY (West Florida,
Biltmore Herbarium) shows a combination of
densely strigillose hairs and four-angled or barely
winged capsules; it apparently arose following hy-
bridization between a parent with strongly winged
capsules (L. alata or L. lanceolata) and one that
was pubescent (L. pilosa, L. ravenii, or L. sphae-
rocarpa). The isodiametric seed surface cells, com-
bined with the fact that these plants shed their
pollen grains as tight tetrads clearly suggest L.
lanceolata and L. pilosa as the parents. Two other
collections identified as this hybrid are also from
lorida

Brass 15532 (GH, US).
Ludwigia lanceolata also intergrades with L.
suffruticosa. For example, putative parents and
introgressed hybrid populations were found in the
same sandy ditch by a prairie in Hillsborough Co.,
Florida (Peng 4324, 4328, MO). The leaves of
the hybrids were narrow like those of L. suffruti-
cosa, but the stems were well branched above the
middle. The flowers are produced in somewhat
congested racemes at the top of each branch, and
the capsules were obpyramidal and weakly four-
angled. Peng 4324 had 85% stainable pollen and
formed 16 bivalents in meiosis.

Distribution. The habitats of L. alata include
ditches; shores of ponds and lagoons; peaty or

pits in open pine woods; swampy, flat outcrops of
oolitic rocks; wet savannas; tidal flats; brackish
marshes; sandy beach strands; and hammocks. This
species occurs along the eastern Coastal Plain from
southeastern Virginia through eastern North Car-
olina, with sporadic populations in eastern South
Carolina and Georgia; it reaches its southern limit
at localities scattered throughout the Florida pen-
insula. To the west this species extends along the
Gulf Coast through the Florida panhandle into
southern Alabama, Mississippi, and extreme east-
ern Louisiana (Fig. 38). Proctor (1982) reported
disjunct populations from Jamaica. Flowering from
June to October; fruiting from July to November.

Ludwigia alata has been confused with L. lan-
ceolata (Long & Lakela, 1976; Raven & Tai,
1979; Godfrey & Wooten, 1981; Wunderlin,
1982; Clewell, 1985), owing to their similarity in
being glabrous, apetalous, and most notably, in
having winged, obpyramidal fruits, a character not
shared by other species of sect. Microcarpium.
Raven & Tai (1979) reported the chromosome
numbers of L. alata. They reported tetraploid
counts of n — 16 and hexaploid counts of n — 2
as a result of not differentiating L. lanceolata from
L. alata. It has now become clear that L. alata
is a hexaploid and L. lanceolata is a tetraploid
(Peng, 1988). In my biosystematic study (1988), I
reported that reciprocal artificial hybrids between
the two species exhibit a modal meiotic configu-
ration of 16 bivalents and 8 univalents, which
suggests that they have two genomes in common.
Similar results were obtained when the hexaploid
L. alata was crossed with any of the other tetra-
ploid species of sect. Microcarpium. Cytogenetic
and morphological data suggest that L. alata may
have originated following hybridization between the
tetraploid L. lanceolata and the diploid L. micro-
carpa or populations ancestral to them (Peng,
1988).
Despite their superficial resemblance, Ludwigia
alata differs sharply from L. lanceolata in that
the pollen grains are shed singly in L. alata and
as tetrads in L. lanceolata (Praglowski et al., 1983),
and the seed surface cells are columnar in £. alata
vs. suborbicular in L. lanceolata. Other characters
used by monographers to differentiate the two
species include seed shape (ovoid in L. alata vs.
cylindric in L. lanceolata) and sepal shape and
size (slightly longer in length than width and nearly
as long as the capsule in L. alata vs. about as long
as wide, shorter than the capsule in L. lanceolata)
(Small, 1933; Munz, 1944, 1965). These char-
acters, however, are not always clear and reliable.
The leaf base is usually decurrent in Ludwigia
alata, resulting in the winged stem. The wings are
up to 1.8 mm wide in extreme cases. In L. lan-
ceolata, by contrast, the stems are nearly smooth.
However, the character of the winged stem in L.
alata is too variable to be diagnostic.
Ludwigia alata has, like all other tetraploids of
the section, lost its petals in the course of evolution.
In a specimen collected from Duval Co., Florida
(Creager 639, NCU), one vestigial petal is present
on a single flower. Progeny of Peng 4205 collected
from Dade Co., Florida, exhibited minute, vestigial
petals on some flowers, too, in greenhouse culti-
vation. Although normally lacking petals, L. alata
has whitish sepals that flare outward. This char-
acter, along with the fact that the distance between
the androecium and the gynoecium is such that
mechanical self-pollination cannot usually occur,
indicates that L. alata is an obligate cross-polli-
nator. By contrast, L. lanceolata has greenish,
ascending sepals and is modally self-pollinating.
Ludwigia alata and L. lanceolata are compared
in Table 5.
Ludwigia alata occurs with L. curtissii, L.
linifolia, L. microcarpa, L. pilosa, L. simpsonii,
and L. suffruticosa. Natural hybrids between L.
alata and L. pilosa, and between L. alata and L.
suffruticosa, all of which require insect vectors to
effect pollination, are abundant. (See Peng [1988]
for voucher information of such natural hybrids.)
The hybridity of field populations of L. alata x
L. pilosa is initially suggested by the combination
of the winged ovaries/capsules and minute, uni-
form pubescence found in these plants. Of the 15
taxa in sect. Microcarpium, only L. alata and L.
lanceolata have winged capsules, and they are
glabrous. Ludwigia pilosa and L. ravenii are con-
sistently pubescent, and L. sphaerocarpa is vari-
able in vestiture; none of them has winged capsules.
The parentage of the hybrids between L. alata (n
— 24) and L. pilosa (n — 16) is further verified
by (1) their reduced level of stainable pollen (ca.
45-70%, which is indicative of a heteroploid cross),
and (2) a mixture of columnar and isodiametric
cells and some other irregular cells on their seed
surface (among the pubescent putative parental
species, only L. pilosa differs significantly in the
seed surface pattern from L. alata).
Natural hybrids between Ludwigia suffruticosa
(n = 16) and L. alata (n = 24) are difficult to
recognize in the field. They are very similar to L.
alata in general aspect, having winged capsules
and slightly winged stems, as well as pollen grains
are borne only in the upper leaf axils of each

a result of reduced seed set; and their seed surface

Distribution. Plants of L. sphaerocarpa grow
in drainage ditches, on stream or pond shores, and
in river marshes, swales, swamp forests, edges of
limestone sinks, peaty bogs in pastures, and inter-
dunal marshes. This species has an extensive dis-
tribution along the Atlantic coast, ranging from
Massachusetts to northcentral Florida. To the west
it extends through the panhandle of Florida, south-
western Georgia, southeastern Alabama, central
and southwestern Louisiana, and reaches eastern
Texas. Disjunct populations occur in southcentral
Tennessee, extreme southwestern Indiana, along
Lake Michigan in northeastern Illinois and north-
western Indiana, and in westcentral New York (Fig.
52). Flowering from June to September; fruiting
from August to November.

Ludwigia sphaerocarpa is highly polymorphic.
Its variability is largely the result of its wide geo
action of differential adaptation and genetic drift
made possible by its pattern of distribution, and its
possible hybrid nature (see below). Hybridization
with L. pilosa in regions where their ranges overlap
apparently provides an important source of vari-
ability in L. sphaerocarpa.
Populations of this species consist of individuals
that vary in overall pubescence, leaf shape and
size, fruit size, and density of fruits on branches.
Fernald & Griscom (1935) recognized var. jun-
gens, var. macrocarpa, and var. deamii based on
various combinations of these characters. In their
treatment, the varieties were separated as follows:
Rameal leaves strongly reduced, glabrous or pubes-
cent, lanceolate.
Mature hypanthium small, 2.5-3.2 mm long,
m broad, averaging broader than long.
Hypanthium pubescent; leaves narrowly line-
ar-lanceolate and attenu ate Lees
COMIS var. "typica" [var. TM
Hypanthium, branches, and leaves pubescent;
eaves more broadly lanceolate, not a
Haire penu rum larger, 3.5-4.6 mm pe ng,
3.2-4 mm broad, averaging longer than broad
var. macrocarpa
Rameal leaves scarcely smaller than the primary
nes, pubescent, narrowly oblong; stems pubes-
cent; hypanthium eE 3 mm long, about
as wide var. deamii
In his revisions of the New World species of
pad Munz (1944, 1965) reduced var. deamii
o synonymy under var. jungens and presented
ds following key to the varieties:
Fruit crowded on branches, 3.5-4.5 mm long, not
as wide. Massachusetts to New Jersey .....
var. macrocarpa
Fruit not ue on branches, 2-3.2 mm lon
usually
Main stems id leaves usually glabrous; principal
leaves linear-lanceo ate and over 7 cm lon
Rhode Island to Florida .......... var. sphaerocarpa
Main stems and leaves ae io to strigose, lan-
ceolate, usually less than 7 cm long. New Jersey
to North Carolina, Michigan, and Indiana .....
var. jungens
A study of numerous herbarium specimens not
available to Fernald & Griscom (1935) and Munz
(1944, 1965) has revealed that correlations be-
tween these characters are not consistent; the
often intergrade. Indeed Munz (1944) noted that
r. typica (the typical variety) and var. jungens
Maot freely.” Under Ludwigia sphaerocar-
pa var. macrocarpa, he also wrote, “New Jersey
material is sometimes difficult to distinguish from
var. typica (the typical variety)." In my opinion,
it is best to treat L. sphaerocarpa as representing
an assemblage of variable populations without rec-
ognizing the infraspecific taxa. These populations
share the following diagnostic characters: subglo-
bose capsules, diminutive bracteoles (shorter than
1.5 mm long), and ovate-deltoid, yellowish, con-
spicuous sepals.
Volume 76, Number 1

Peng 281
Ludwigia sect. Microcarpium
It is also of interest to note that, although the
seed surface cell pattern is generally very regular
within populations of members of Ludwigia sect.
Microcarpium (Figs. 19-28, 30-34), this is not
the case for L. sphaerocarpa (Fig. 29). The seed
surface is arranged in columnar cells both trans-
versely elongate and parallel to the seed length,
the former alignment often predominating in the
central part of the seeds. Seeds with variously
oriented surface cells are also seen in some pop-
ulations. Comparison of the seed surface pattern
in populations of L. sphaerocarpa with that of
various artificial hybrids strongly suggests that ear-
lier hybridizations within the interfertile tetraploid
group of sect. Microcarpium may have resulted
in this widespread series of populations that are
more or less stabilized in some of their character-
istics, and such hybridizations may still be contrib-
uting to the variability of this series of populations.
The biosystematic study of Ludwigia sect. Mi-
crocarpium (Peng, 1988) demonstrated that hy-
brids between species that differ in their seed sur-
face cell pattern always show a mixture of cell
types or cells of intermediate shapes and sometimes
of randomly oriented cells. Similarly, hybrids re-
sulting from crossing a densely hirtellous species
with a glabrous one always exhibit minutely villous
or strigillose pubescence. Of the tetraploid Lud-
wigia taxa that are interfertile with L. sphaero-
carpa, L. ravenii and L. glandulosa subsp.
"pehyearpe are the only ones with columnar seed
lls elongate transversely to the seed length,
= mw L. polycarpa and L. glandulosa subsp.
glandulosa are the only taxa with columnar seed
surface cells elongate parallel to the seed length.
Both subspecies of L. glandulosa, having narrow,
subcylindrical capsules, are unlikely to be parents
of L. sphaerocarpa. In seed surface pattern and
overall pubescence, L. ravenii (densely hirtellous)
and L. polycarpa (glabrous) seem to be suitable
parental candidates. However, that they both have
oblong-obovoid capsules and are highly autoga-
mous, in contrast to subglobose capsules and out-
crossing habit of L. sphaerocarpa, renders it un-
likely that they have been involved directly in the
formation of L. sphaerocarpa. One or possibly
both parents of L. sphaerocarpa are likely extinct.
The morphological variation in Ludwigia
sphaerocarpa is further complicated by its fre-
quent natural hybridization with L. pilosa, which
has apparently resulted in many hybrid swarms or
introgressed populations. These plants generally
exhibit varying degrees of intermediacy in diag-
nostic characters such as seed surface pattern,
overall pubescence, bracteole size, sepal shape and
size, and leaf shape. The following specimens show
intermediacy in at least two of the above characters
or a combination of some of the diagnostic features
of L. pilosa with some of those of L. sphaero-
carpa:

Some of the above putative hybrid populations
are from central and southern Florida, where nei-
ther typical Ludwigia pilosa nor L. sphaerocarpa
occur (Peng, 1988, fig. 22). This suggests that
their physiological characteristics, and thus their
ecological tolerances, may differ from those of the
parents in such a way as to allow them to occur
in novel habitats and areas where neither of their
parents can survive
The following collections are unusual in being

Judged by their morphology as well as their full
seed set, these plants are more likely to be mutants
showing an ancestral trait rather than hybrids be-
tween Ludwigia sphaerocarpa and one of the
petaliferous species of sect. Microcarpium.
Almost all populations of Ludwigia sphaero-
carpa. are at least sparingly strigillose, especially
on the ovary /capsule walls. The following two gla-
brous collections from Louisiana are exceptional:
.S.A. LOUISIANA: Cameron Parish, in “The Pool,"
Lacassine Wildlife Refuge, Thieret 16410 (DUKE, GA,
MO, SMU). Rapides Parish, Red River, 1840, Hale s.n.
(US).
They seem to parallel the glabrous variants of
Ludwigia linearis (see above) in which a few gla-
brous plants may grow intermixed locally with
densely strigillose individuals.
Ludwigia sphaerocarpa is one of the few species
in sect. Microcarpium in which the distance be-
tween the androecium and the gynoecium is such
that self-pollination is impossible without the inter-
vention of pollen vectors. Although the flowers of
L. sphaerocarpa are apetalous, their sepals are
adaxially yellowish. This, along with the bright yel-
low nectary disc, which produces copious nectar,
attracts many insects to the flowers of this appar-
ently largely outcrossing species.
n the field, Ludwigia sphaerocarpa grows with
L. glandulosa, L. linearis, L. microcarpa, L. pi-
losa, and L. polycarpa and hybridizes with all but
the small-flowered, modally selfing L. microcarpa.
The natural hybrids generally exhibit intermediate
morphology, most notably in fruit shape and size,
bracteole length, overall pubescence, and seed sur-
face cell pattern. The fruits are plump and contain
abundant seeds in homoploid (tetraploid) hybrids.
In the heteroploid (triploid) L. sphaerocarpa (n =
16) x L. linearis (n — 8), one to four petals were
present in most flowers, and seed set was negligible.
In the experimental greenhouse, artificial hy-
brids have been synthesized between Ludwigia
sphaerocarpa and the diploid L. linearis, L. mi-
crocarpa, the tetraploid L. glandulosa, L. poly-
carpa, L. suffruticosa, L. lanceolata, L. pilosa,
the hexaploid L. alata, and the octoploid L. cur-
tissii (Peng, 1988).

Ludwigia pilosa is a distinctive species in sect.
Microcarpium characterized by being densely hir-
tellous throughout; reddish brown leaf midveins
especially abaxially; sepals elongate-triangular,
creamy, and often tinged with pink, reflexed at the
tips; and capsules subglobose to somewhat oblong-
obovoid, with a pair of long bracteoles attached
slightly above the base. The only species that has
consistently been confused with L. pilosa is the
recently named L. ravenii (Peng, 1984). The sim-
ilarity in these two species is in aspect and in the
vestiture. They differ in many other characters,
notably floral parts and breeding systems. Lud-
wigia ravenii is modally autogamous, with obscure
greenish sepals, and all of its floral parts are sig-
nificantly smaller than those of L. pilosa. Further,
the seed surface cells are transversely elongate
rather than subisodiametric.
The flowers of Ludwigia pilosa, in contrast,
are unable to undergo mechanical self-pollination.
Their showy sepals and copious nectar, which is
produced by the nectary disc, unfailingly attract
various insect visitors such as ants, wasps, bum-
blebees, honeybees, and moths to effect pollination.
Ludwigia pilosa grows with diploid L. linifolia,
L. microcarpa, tetraploid L. glandulosa, L. lan-
ceolata, L. ravenii, L. sphaerocarpa, L. suffru-
ticosa, and the hexaploid L. alata, which is closely
allied to the tetraploid species group. It forms fertile
hybrids with probably all tetraploid species and with
L. alata when they grow together. Natural hybrids
between L. pilosa and L. ravenii are presumably
rare (L. ravenii is rare itself) and difficult to detect.
An intersectional hybrid between L. pilosa and L.
arcuata (n = 16; sect. Dantia) was found in Mobile
Co., Alabama (Peng, 1988). All natural hybrids
are intermediate morphologically, having vestiture
similar to that of L. pilosa but shorter and other

Ludwigia sect. Microcarpium
features diagnostic of the other putative parents
(e.g., the winged fruits of L. lanceolata, elongate
capsules of L. glandulosa, and additional features).
Two such hybrids have previously been named: L.
capitata B pubens Torrey & A. Gray (= L. pilosa
x L. suffruticosa) and L. simulata Small (= L
PE X L. lanceolata). Kral (1976) reported a
tension of L. polycarpa to Alabama, based,
in fact; on a natural hybrid population of L. pilosa
x L. glandulosa. The only species that hybridizes
extensively with L. pilosa and produces many hy-
brid swarms or introgressed populations is L. sphae-
rocarpa. Plants of these populations exhibit a vary-
ing degree of intermediacy between the two species.
They are discussed further under L. sphaerocar-
pa.
Hybrids between Ludwigia pilosa and the other
tetraploid species or the hexaploid L. alata are
readily synthesized in the experimental greenhouse
and are quite fertile. It is generally difficult to obtain
hybrids between L. pilosa and diploid species or
the L. curtissii complex. Floriferous and vigorous
hybrids of L. pilosa X L. linifolia and L. pilosa
X L. curtissii, however, were obtained. Seed set
was nonexistent or negligible in these hybrids.

Distribution. Ludwigia ravenii occurs in wet,
peaty habitats, such as ditches or margins of ponds,
bogs, and swamps. It is found as scattered popu-
lations in coastal southeastern Virginia, eastern
North Carolina, and southeastern South Carolina
and with somewhat disjunct populations in north-
eastern Florida (Fig. 56). Flowering from July to
September; fruiting from August to October.
Specimens examined are cited in full in Peng
(1984).
This recently discovered species consists of scat-
tered, morphologically very uniform populations.
Owing to its densely hirtellous vestiture and relative
rareness, it was previously not well understood and
was confused with Ludwigia pilosa, the only other
species of sect. Microcarpium that is consistently
densely hirtellous; that species, however, is wide-
spread and common. As was shown in the table
comparing L. ravenii with related species (Peng,
1984), L. ravenii is very distinct from L. pilosa.
Ludwigia ravenii has small inconspicuous flow-
ers with greenish sepals and short stamens and
styles. Its anthers are firmly appressed to the stig-
ma shortly after anthesis. These characteristics
strongly suggest that it is modally autogamous. This
was corroborated by my field study at the type

locality (Peng, 1984): for two hours by the ditch
where L. ravenii grew, I did not observe any insect
visitors, whereas 0.5 mi. away in the same ditch,
I witnessed a swarm of honeybees visiting and
hovering over flowers of a population of L. pilosa.
Ludwigia ravenii does not appear to grow ag-
gressively. It starts to form stolons only late in its
fruiting season (September to October). Unlike most
other tetraploid members of sect. Microcarpium,
these stolons are usually slender and short, resem-
bling those of L. microcarpa. Consequently, the
populations consist of scattered individuals instead
of large colonies connected by stolons, as is typical
in L. pilosa and other species.
Live plants of Ludwigia ravenii were not col-
lected until after the completion of my biosyste-
matic study of Ludwigia sect. Microcarpium, so

members of the section remain obscure. The ex-
tensive crossing data already available for other
species clearly demonstrate, however, that pollen
stainability and seed set are high in hybrids between
any two tetraploid species, no matter how different
morphologically they are (Peng, 1988). Circum-
stantial evidence thus suggests that L. ravenii is
almost certainly interfertile with other species of
the tetraploid group of sect. Microcarpium.

Distribution. Plants of Ludwigia microcarpa
grow in roadside ditches, ponds and
streams at the borders, low meadows, low areas in
open woods, edges of swamp forests, brackish
marshes,
marshes, hammocks, and solution pits of limestone
on marl prairies. This species occurs along the
Atlantic coast of North and South Carolina and
Georgia, and throughout the Florida peninsula. It
extends westward across the panhandle of Florida,
southern Alabama, reaching southern Mississippi,
with a single population in southwestern Louisiana.
To the north, L. microcarpa occurs through west-
ern Georgia and central and western Alabama to
southcentral Tennessee. Scattered populations are
found in northcentral North Carolina and south-
central Missouri (Fig. 58). Furthermore, L. mi-
crocarpa occurs on several Caribbean islands, in-
cluding the Bahamas, Cuba, and Jamaica. Flowering
and fruiting throughout the year.

Ludwigia microcarpa is the only diploid species
of sect. Microcarpium that is apetalous and has
more or less spatulate leaves. It has the smallest
stature, leaves, flowers, and fruits and has the
fewest seeds (ca. 10—20) per capsule of any species
in the section. Occasionally it may be confused
with plants of the “L. curtissi complex” (including
a hexaploid, L. simpsonii, and an sopla, E
curtissii), which have similarly spatulate leaves a
turbinate fruits. It is, however, Lon maet A
the “L. curtissii complex" by its minute capsules
(1-1.5 mm long), which are shorter than or sub-
equal to the sepal, its nectary disc of four flat
greenish spots, and its reddish seeds. For detailed
comparison, see Table 6
Ludwigia microcarpa is uniform in reproduc-
tive structures but variable in vegetative habit. The
stems are, as a rule, erect and usually well branched
but are sometimes single. The stems and branches
are straight or slightly zigzag. In outline, the plants
subequal, ascending branches throughout the nodes;
or they are triangular or ovate when the branches
are gradually shorter from lower nodes up. The
stems are normally annual and herbaceous; the
plants may perennate either by forming stolons or
by sending new shoots up directly from the spent
stem base of the previous year. Woodiness is seen
in some Florida specimens, presumably as a result
of a favorable climate. The following specimen from
Leon County, Florida, has an exceptionally woody
base about 8 mm thick: sandy alluvium bordering
wet woodland, Ochlockonee River, W of Tallahas-
see, Godfrey 73131 (MO).
Most plants of Ludwigia microcarpa start to
flower when young; it is common to find plants 5-
10 cm high with flowers/fruits. The apetalous flow-
ers are very small, with a tiny, greenish nectary
disc from which a small amount of nectar is pro-
duced. Mechanical self-pollination apparently pre-
dominates in this species. In the experimental
greenhouse, however, it
crossed to the diploid L. linifolia and L. linearis,
tetraploid L. glandulosa, L. lanceolata, L. poly-
carpa, L. sphaerocarpa, and hexaploid L. alata
and L. simpsonii; these combinations have resulted
been successfully
in the production of vigorous, floriferous hybrids
(Peng, 1988). None set any seed. The F, hybrids

loids were consistently petaliferous, suggesting that
petal formation is controlled by a dominant gene.
In other aspects, these F, hybrids were intermediate
between their parents. Hybrids between L. micro
arpa and species of higher ploidy level generally
resembled the latter but tended to have smaller
leaves and flowers.
Ludwigia microcarpa grows with L. alata, L.
curtissii, L. glandulosa, L. linearis, L. linifolia,

Natural hybrids have been found between L. mi-
crocarpa (n — 8) and both L. simpsonii (n — 24)
and L. curtissii (n = 32), both of which resemble
L. microcarpa morphologically and share a com-
mon genome with that species (Peng, 1988). Since
L. simpsonii and L. curtissii differ only in quan-
titative characteristics, which often overlap, it is
impossible to distinguish between L. microcarpa

without knowing the chromosome number, or with-
out seeing the populations in m field. These hy-
brids are usually readily recognizable by their erect
stems; small and oblanceolate to spatulate leaves;
apetalous flowers; elevated nectary discs; and mi-
nute, obpyramidal ovaries that abort after anthesis.
he corners of the ovary/capsule often appear
winged to some extent, apparently as a result of
the aborted ovaries, which fail to develop into seeds
in the locules of such hybrid individuals.
Hybrid populations between Ludwigia micro-
carpa and L. simpsonii are apparently common
in Florida, where the two species grow in the same

habitats, often intermixed. These plants have a
modal meiotic configuration of 8 bivalents and 16
univalents (Peng, 1
Confirmed hybrid populations of Ludwigia mi-
crocarpa X L. curtissii were found in Martin Co.,
Florida, 4.3 mi. E of Okeechobee and Martin coun-
ty line, on FL 710, at Brady Ranch (Peng 4202,
MO). Here they occurred along with putative par-
ents by a wide depression between the highway
and a railroad. Plants of L. microcarpa grew along
the swamp border, whereas plants of L. curtissii
stood in deeper water but were not as abundant as
the former. Hybrid plants were scattered between
them. The hybrids formed 8 bivalents and 24 uni-
valents at meiosis (Peng, 1988).
Intersectional hybrid populations of Ludwigia
microcarpa with L. palustris (sect. Dantia) were
found in several counties of North Carolina, Geor-
gia, and Florida (Peng, 1988). Their leaves were
bopposite or opposite; their fl
apetalous, with minute ovaries, and aborting after
anthesis; and the stems were prostrate and rooting
at the nodes to ascending, suberect, or both. The
combination of alternate leaves with a more or less
prostrate habit in North American Ludwigia is
usually indicative of hybridization between plants
of sect. Microcarpium and sect. Dantia.

polyploid complex, with the diploid L. microcarpa
evidently having played a role in the formation of
the other species (Peng, 1988). Its distinctiveness
from the diploid L. microcarpa is readily perceived
in capsule size, shape of nectary disc, seed color,
and seed number per capsule. The characters sep-
arating L. simpsonii and L. curtissii, however,
are nearly always quantitative and often overlap.
Raven & Tai (1979) indicated that the diagnostic
characters separating L. curtissii and L. simpson-
ii, such as capsule shape and size and leaf shape,
are not correlated with chromosome numbers, and
that the two species tend to converge in the ex-
perimental greenhouse. For reasons of this sort,
these two species have frequently been merged
under L. curtissii in the recent literature (e.g.,
Long & Lakela, 1976; Raven & Tai, 1979; God-
frey & Wooten, 1981; Wunderlin, 1982). By con-
trast, basing conclusions on abundant fieldwork and
greenhouse and chromosome studies, I (1988) ob-
served that the difference in chromosome number
is correlated with mature capsule size. All plants
with n — 24 have capsules 1.5-2(-2.5) mm long,
whereas those with n — 32 have mature capsules
(2-)2.5-4(-4.7) mm long. The morphology of
plants with n — 24 fits closely the description of
L. simpsonii, and the morphology of n — 32 plants
clearly corresponds to that of L. curtissii (including
L. spathulifolia). Comparison of these two species
and the diploid L. microcarpa is in Table 6.
Although Ludwigia simpsonii and L. curtissit
frequently are found in the same locality, they
appear to be ecologically distinct and seldom occur
side by side. Ludwigia simpsonii tends to grow
along roadsides with other weeds in moist sandy
soil. Ludwigia curtissii usually grows farther from
roadsides, sometimes mixed with tall grasses or
sedges, in black muck and often in deep standing
water.
Ludwigia simpsonii sometimes grows with L.
alata, L. curtissii, and L. microcarpa. Proven
natural hybrids are known only of L. simpsonii X
L. microcarpa; they occur in several scattered
counties in Florida (Peng, 1988). These hybrids
showed a modal meiotic configuration of 8 bivalents
and 16 univalents and 4-24% stainable pollen.
Their ovaries aborted after anthesis. Ludwigia
simpsonii may form natural hybrids with L. cur-
tissii, but such hybrids would be virtually impos-
sible to pick out without studying their chromo-
somes and would probably be identified as one of
their putative parents. Artificial hybrids between
these two closely related species have been syn-
thesized; they produced moderate numbers of seeds
and had ca. 80-90% stainable pollen. They con-
sistently showed a meiotic configuration of 24 bi-
valents and 8 univalents, which indicated that chro-
mosomes of the three genomes in L. simpsonii pair
with homologues in L. curtissii, leaving the eight
additional chromosomes in this species unpaired.
Based on morphological features and crossing re-
lationships, the octoploid L. curtissii was probably
derived following hybridization between a petalif-
erous, narrow-leaved diploid similar to L. linearis
or L. linifolia and the hexaploid L. simpsonii
(Peng, 1988).
Intersectional hybrids of Ludwigia simpsonii
and L. repens (n — 24; sect. Dantia) have been
found growing intermixed with both putative par-
ents. These plants exhibited few, if any (0-1),
associations of chromosomes at meiosis (Peng,
1988), which corroborated an earlier report by
Schmidt (1967). The lack of chromosome pairing
in hybrids strongly suggests that the three genomes
of L. simpsonii are distinct from one another and
are not homologous with any of the genomes pres-
ent in L. repens. Judged by the fact that L. simp-
sonii often has opposite or subopposite leaves near
the base of the stem or at the seedling stage, with
a somewhat ascending, decumbent, or occasionally
prostrate habit, it seems likely that it originated
from hybridization between the diploid L. micro-
carpa, to which it is similar morphologically and
with which it shares one genome, and a possibly
extinct member of sect. Dantia with prostrate stems
and opposite leaves.
Plants from the following collections are excep-
tionally fully prostrate and root at the nodes:
U.S.A. FLORIDA: Collier Co., 13 mi. N of U.S. 41, on
U.S. 29, in vast grassy field behind roadside ditches (Big
Cypress Swamp), Peng 4268 (MO), 4273 (in part, MO).
They grow side by side with erect plants but are
otherwise normal, small-fruited L. simpsonii, ex-
hibiting 24 pairs of chromosomes in meiosis and
setting abundant fruits with viable seeds.
Artificial hybrids between Ludwigia simpsonii
and the diploids L. linearis, L. linifolia, L. mi-
crocarpa, the tetraploids L. glandulosa, L. lan-
ceolata, the hexaploid L. alata, and the closely
related octoploid L. curtissii have been synthe-
sized, although with difficulty in some cases. Except
or L. simpsonii X L. curtissii, which is highly
fertile, all other combinations had 3-20% stainable
pollen and produced very few, if any, seeds.

Ludwigia curtissii and L. simpsonii are both
highly variable in habit and leaf shape and are
often difficult to distinguish; the only consistent
distinguishing character is the size of mature cap-
sules. These two species are unique in sect. Mi-
crocarpium in having loculicidal capsules and in
having, along with the diploid L. microcarpa, more
or less spatulate cauline leaves. Their capsules de-
hisce by four longitudinally lenticular slits opposite
the loculi. When dehiscence is complete, the cap-
sule is split into four basally united parts topped
with persistent but slightly shriveled sepals. This
type of capsule dehiscence is highly specialized and
has an anatomical basis (Peng & Tobe, 1987).
Ludwigia curtissii and L. simpsonii are also dis-
tinct in that they are the only species in sect.
Microcarpium that rarely produce true stolons.
From the perennial base of the previous-year stem
they form new shoots that ascend at first and soon
become erect.

Ludwigia sect. Microcarpium
Some populations of Ludwigia curtissii from
the Everglades of southern Florida and the Ba-
hamas tend to have larger capsules (3.5-4.7 mm
long) and were named L. spathulifolia by Small
(1933). As their variation pattern closely parallels
that of L. curtissii s. str., and they are octoploids
with n — 32, they are here considered as variants
of the slightly rdg fruited L. curtissii that do
not warrant taxonomic recognit lon, as was sug-
gested by Long & Lakela (1976), Raven & Tai
(1979), Godfrey & Wooten (1981), and Wunder-
lin (1982).
Ludwigia curtissii co-occurs with L. alata, L.
linifolia, L. microcarpa, and L. simpsonii and
hybridizes with the diploid L. linifolia and L. mi-
crocarpa, forming F,s that form flowers but not
seeds. Ludwigia curtissii X L. microcarpa ex-
hibited 8 bivalents and 24 univalents at meiosis.
The pollen stainability was 1676 (Peng, 1988). As
discussed above, natural hybrids between L. cur-
tissii and L. simpsonii probably occur but would
be difficult to recognize. Like L. simpsonii, L.
curtissii forms intersectional hybrids with L. re-
pens (n — 24, sect. Dantia) in the field. Such
plants are vigorous and somewhat prostrate or sub-
erect; they have alternate and opposite or subop-
posite leaves, but do not form viable seeds.
n the experimental greenhouse, artificial hy-
brids have been synthesized between Ludwigia
curtissii and the diploid L. linearis and the tet-
raploids L. glandulosa, L. lanceolata, L. pilosa,
L. polycarpa, L. sphaerocarpa, and L. suffruti-
cosa. A few seeds were occasionally produced by
some of the octoploid X tetraploid hybrids.
Compared with Ludwigia simpsonii (n — 24),
L. curtissii (n = 32) is generally taller, more
robust, more often erect, tends to have narrower
and longer leaves, and nearly always has larger
flowers and capsules. Further, the leaves of L.
curtissii are nearly always alternate throughout,
and the flowers occasionally have one to three
vestigial petals. As these two species have three
genomes in common (Peng, 1988), it is apparent
that L. curtissii originated following hybridization
between L. simpsonii and a diploid, petaliferous,
erect species with narrow and alternate leaves,
larger flowers, and longer capsules. The likely can-
didate for such a plant is only to be found in L.
linearis, L. linifolia, the Cub
or their progenitors. Indeed it is even possible that
more than one of the above species hybridized with
L. simpsonii in the past to form the present-day
L. curtissii. If this is true, the morphological vari-
ability observed in L. curtissii is expected

TWO NEW SPECIES OF THE
LUPINUS LANATUS COMPLEX!
Ana Maria Planchuelo? and
David B. Dunn?
ABSTRACT
The Lupinus lanatus complex is a group of closely related species that grow in southeastern Brazil and northeastern
herbaceous, perenn
long or longer, and lar
Argentina. They are
or three-foliate, stipules 3-7 cm
ial or occasionally biennial plants with basal leaves in the juvenile plant simple
e flowers 15-20 mm
long having the banner glabrous and
well reflexed from the wings. Two species, L. magnistipulatus and L. setifolius, are described for the first time.
This group of species appears to be closely re-
lated and can be recognized by the large stipules
3-7 cm or more long and the presence of some
simple or trifoliate leaves at the base of the juvenile
plants. Completely developed leaves from adult
plants have five or more leaflets. They are all
herbaceous perennials or short-lived perennials, or
occasionally function as biennials. The flowers are
commonly 15-20 mm long and glabrous, with the
banner well reflexed from the wings and the sides
turned back. The calyx cup tapers into the pedicel
without the gibbous enlargement that is commonly
present in other lupines.
We are suggesting that this group of species
forms a second lineage derived from L. para-
guariensis, which is thought to be the origin of
the group, since it possesses morphological char-
acteristics reminiscent of the group, including that
the juvenile leaves and the first leaf produced on
the lateral branches are simple. Planchuelo & Dunn
(1984) described L. paraguariensis as showing a
transitional stage between simple- and compound-
leaved species.
Lupinus lanatus has floccose lanate indument
on both sides of the leaflets (see Fig. 1A). Vege-
tatively it has been described as forming perennial
mats up to four feet in diameter in sand dunes,
with new growth developing seasonally from the
tips of the stems which survive under the sand.
Lupinus magnistipulatus, described in this paper,
is similar to L. lanatus in the perennial condition
but has less lanate hair coating (see Fig. 1B), and
as its name suggests, the former develops a much
larger free tip on the stipules. Lupinus setifolius,
also described in this paper, appears to be biennial.
The large free tip of the stipules and the loss of
the lanate indument (see Fig. 1C) suggest the latter
as a derivative from L. magnistipulatus.
The species L. multiflorus, L. albescens, and
L. aureonitens, treated by Planchuelo & Dunn
(1984), are relatives of this complex. They have
caespitose perennial habit and a narrow free tip of
the stipules like L. lanatus but develop a much
denser indument that grades from densely short-
lanate to densely sericeous, completely hiding the
leaf surface.

unusually large stipules, some of them 6 mm wide.
All the others have most of the stipules under 5
mm wide. Although all the morphological charac-
teristics of the large-stipuled specimens are those
of the species, the enlargement of the free tip of
the stipules suggests relationship with L. magni-
stipulatus and even crossing between the two
species.
Lupinus lanatus occurs in the southernmost
states of Brazil and in Misiones, Argentina. The
plants are reported growing in open places and
dunes.

The name Lupinus magnistipulatus was sug-
gested several years ago by Prof. A. Burkart on
herbarium specimens. Some of the specimens cited
here were labeled by Burkart as a new species, L.
reitzii. Our interpretation of the material is that
these specimens are juvenile plants and do not differ
otherwise from the others. Therefore we have not
recognized L. reitzii.
The new species apparently grows only in south-
eastern Brazil in the states of Santa Catarina and
Paraná at altitudes from 700 to 1,650 m. Flow-
ering occurs from late October to late January.

The description was based solely on the holotype.
The taxon appears to be closely related to L. mag-
nistipulatus. The flowers are smaller and the base
of the calyx has a ridge above and below at the
pedicel, while that of L. magnistipulatus tapers
more gradually into the pedicel.

CONCLUSIONS
The three species, L. paraguariensis, L. al-
bescens, and L. aureonitens, not treated in this
paper are included in the key to facilitate identi-
fication of presumably closely related species. In
seedlings of L. albescens grown from an herbarium
specimen, the first leaf of the plant was simple and
the second three-foliate. This particular charac-
teristic should be common to the group of species
treated in the key, although it is difficult to find in
herbarium specimens. Considering the taxonomic
studies of the genus Lupinus for South America
(Planchuelo-Ravelo, 1984), this complex and its
related species are representatives of the lupines
of the “Atlantic Region" and are the only group
of perennial plants with large compound leaves
growing in the area.

AUGUSTUS FENDLER'S
VENEZUELAN PLANT
COLLECTIONS:

ABSTRACT
Between 1854 and 1858, Augustus Fendler resided in Colonia Tovar, a German village in the Coastal epa
of Venezuela, where he assembled on
map and list of Fendler

In the mid nineteenth century South America
was poorly known botanically compared with most
other parts of the world. At this time, plants gen-
erally were collected by people who traveled through
one or several countries, making plant specimens
along their way (e.g., Ruiz & Pavón; Humboldt &
Bonpland). Few collectors lived in an area long
enough to sample a region thoroughly and collect
the relatively rare species. Augustus Fendler was
a notable exception. He resided four years in Co-
lonia Tovar,’ a small German colony 35 miles west
of Caracas, Venezuela (Rasmussen, 194
collected over 3,000 ferns and flowering plants.
These collections are noteworthy, not only for their
excellence, but also because a great number of new
species were based on his material. To this day,
new species are being described from Fendler's
Venezuelan specimens (e.g., Croat & Lambert,
Although his Venezuelan collections are ex-
tremely important, Augustus Fendler is perhaps
best known for his collections of New Mexican
plants between 1846 and 1847. Gray (1849) pub-
lished an annotated list of Fendler's New Mexican
plants, which Shaw (1982) discussed more re-
cently. Fendler's other collecting trips to Panama,
Venezuela, and Trinidad are not as well known as
those he took in the United States. In Panama,
Fendler (Fig. 1) collected near the Chagres River
for four months in 1849 and 1850. He resided in
Trinidad from 1877 until his death in 1883. His
most valuable collections were made in Venezuela
between January 1854, and September 1858.
This paper is an account of Fendler's life in
Venezuela constructed from his letters to D.
Eaton, G. Engelmann, and A. Gray in the Yale
University Library, Missouri Botanical Garden, and
Gray Herbarium archives, respectively. This cor-
respondence provides insight not only into Fendler,
but also into the difficulties of life as a plant col-
lector in the s. Fendler corresponded with
Engelmann in German and with Eaton and Gray
in English. These lucid and detailed letters are a
chronicle of plant collecting in South America in
the mid nineteenth century and are even more
remarkable since German was Fendler's native lan-
guage

1885; Gray, 1885; Rohl, 1944), Fendler was born
in Gumbinnen, eastern Prussia, in January 1813.
At the age of 12 he was sent to a preparatory
school where he mastered the fine penmanship that
was as delightful to his correspondents as it is to
his present-day historians (Fig. 2). Fascinated with
traveling, Fendler sailed from Bremen to Baltimore
in 1836 and within two years moved to St. Louis.
During a visit to Europe in 1844, Fendler met
Professor Ernst Meyer of the University at Koe-
nigsberg in Prussia, who encouraged him to collect
plants in the western United States and send them
to him for sale. On his return to St. Louis, Fendler

brought his specimens for identification to George
Engelmann, the botanist who advised Henry Shaw,
founder of the Missouri Botanical Garden (Stieber
& Lange, 1986). Fendler and Engelmann struck
up a friendship that spanned nearly 40 years. En-
gelmann later introduced Fendler to Asa Gray, who
described Fendler as “a close, accurate observer,
a capital collector and specimen-maker" (J. L.
Gray, 1893: 341).
After a year of plant collecting in New Mexico,
a failed attempt to collect plants near the Great
Salt Lake, and two sojourns in Arkansas and Lou-
isiana, Fendler settled in Memphis, Tennessee in

1850, and prospered there for four years in the
gas-lamp business (Stieber & Lange, 1986). In
1853, when the lamp-lighting business in Memphis
faltered, he was eager for a change of pace and
wanted to resume collecting plants. He wrote to
Gray on 11 August 1853 about his collecting
plans: “My principal object in going to Caracas is:
to go into a business again, by which I can support
myself. But I hope I shall have plenty of leisure

again I shall aim to make the sets as large and
complete as possible. Do you think 15 sets, each
containing from 1,000-1,500 species of plants
collected about Caracas could meet with a ready
sale?" On 15 August 1853, he wrote Engelmann
that he wished to move to a town near Caracas
because “In a city with a population of 70,000 I
believe to be able to find more security than here,

and secondly, because I believe I shall have a better
climate there. Then also, the wish to live again in
a mountain valley and to be in the vicinity of a
rich mountain flora! without having the difficulties
of long and difficult communication as I found in
Santa Fe."
On the 24th of December 1853, Fendler sailed
for Venezuela from New York harbor,
panied by his chronically ill brother. They arrived
accom-
in La Guaira, Venezuela, on 21 January 1854.
In his day, it took five hours to reach Caracas from
the coast. Upon arriving, he commenced collecting
plants in the vicinity. Prompted by the high cost
of living in Caracas, he went up to Colonia Tovar
after only six weeks. After reaching the settlement,
he wrote to Gray on 16 December 1854: “The
base of the valley is 5,600 ft. above the sea, and
some of the surrounding mountains about 2,000

feet higher .... The road from Caracas leads at
first along a small river, which is very rapid and
has to be crossed 42 times. The valley in which
this river flows becomes at last very narrow and
the road turns off to the left ascending a high
mountain, from the tip of which it leads on in a
westerly course along the very summit of the prin-
cipal mountain range, through the deep shades of
the primitive forest and down the valley of the
Colony."
While at Colonia Tovar, Fendler also corre-
sponded with Joseph Henry of the Smithsonian
Institution, who published Fendler's letters and me-
teorological observations in the Annual Report of
the Board of Regents of the Smithsonian Insti-
tution. Fendler was an ardent amateur meteorol-
ogist and in Venezuela traveled with a barometer,
rain gauge, and thermometer. From his corre-
spondence with Gray, Fendler provided a very rich
description of Colonia Tovar (Fendler, 1857): “The
valley in which Colonia Tovar is situated was, so
late as December, 1841, a perfect wilderness, cov-
ered with primitive forest. Not even the existence
of this valley was known fifteen years ago, neither
to the government nor to its owner, although it is
only thirty-five miles west of Caracas, the capital
of Venezuela, and in a straight line cannot be more
than twelve miles from the sea. And when an at-
tempt was made to explore this region not even a
guide could be found for the small exploring party
of fifteen men, headed by Colonel Codazzi, a skillful
ns A, 2 UR A
officer and compiler of the new map of Venezuela.
When this party at last succeeded in crossing this
region and reaching the sea-shore, they thought
they had achieved a most extraordinary thing, (to
cross a distance of twelve miles in six days;) and
after they had returned to their homes none of
them had a desire to do the feat over again. This
was a party of natives. And when, at a later period,
after the establishment of the colony, another skill-
ful engineer found, with a party of colonists, his
way to the opposite port of the sea-shore, the party
did not venture to go back the same route, but
rather chose the way by sea to Laguayra, from
there to Caracas and back to the colony, a very
circuitous route certainly. Such is the nature of
this mountain region, with its precipices, waterfalls,
deep ravines, and its dense, almost impenetrable
primeval forests.
Shortly after arriving in Colonia Tovar, Fendler
bought a small farm in 1854 for 47 dollars. He
described his new home in his letter to Gray of 16
December 1854: “My cottage stands on a small
hill which is projecting from the sloping side of a
mountain overlooking the greater part of the Col-
ony. On the slopes of this little hill we have made
terraces planted with Musa sapientum, with apple
trees, Palms (Oenocarpus utilis), and stately tree
ferns 14 feet high. Near the brown polished stem
of the Palm the clear arch of a fountain (9 feet
high) glitters in the tropical sun sending unceasingly
its sparkling little stream to the top of the young

Palm. This fountain I made in a few days without
outlay of money. Two pieces of the trunk of Cerox-
ylon andicola served as pipes." Fendler clearly
enjoyed Colonia Tovar: “A visitor who never before
lived in a valley like this finds here many pecu-
liarities of vegetation, surface and climate which
make him feel that he is not far off the land of
perpetual peace; for he has entered the happy
region of the ferns, the 'tierra templada de los
helechos.' There is no scorching summer's heat,
no fearful winter's cold, neither tornados to dev-
astate the country nor gales to blind the inhabitants
with sand and dust or penetrate their clothes and
flesh with piercing frost" [Fendler to Gray, 16
December 1854]. His years in the village were
the most enjoyable time of his life, and later letters
indicate that he very much would have liked to
return there [Fendler to Engelmann, 20 July 1882,
Trinidad ].
During his first year at Colonia Tovar, Fendler
devoted much of his time to plant collecting. He
wrote to Professor Henry: “In collecting botanical
specimens, I have penetrated, without companion,
the wilderness around in different directions, also
that on the other side of the principal mountain
range towards the sea, and can testify to the dif-
ficulties and hardships which are met with in ex-
ploring such a country . . . . In these woods, where
the rays of the sun never touch the ground, there
it is where moisture and a cool temperature reign
forever. The trunk of every tree and its branches
are covered with Ferns, Lycopodiaceae, Mosses,
Hepaticae, Lichens, Orchids, Bromeliads, Araceae
and besides Piperacae with many exogenous plants
too numerous to mention” (Fendler, 1857).
Fendler wrote in detail to Gray, who had offered
to enlist subscribers for his sets of plants. “I have
already 8 boxes full of dried plants. The most
attention I have hitherto paid to ferns of which I
have 255 species, most of them complete; other
plants I have not yet enumerated. For the last four
or five weeks I have been employed with arranging
my collections but have not yet finished. The fine
dry weather which is now approaching urges me
again to renewed activity in the field. The woods
here are very dense and impenetrable without a
sabre. The neighboring country is much diversi-
fied" [Fendler to Gray, 16 December 1854].
“Of Palms I have collected 6 species, of which
5 grow in the colony. Tree ferns 9 or 10 species.
Cruciferae and Umbelliferae are represented only
by 2 or 3 species. 1 do not intend to send plants
until I can send something complete, and until I
can ascertain the safest way to forward them"
[Fendler to Gray, 16 December 1854]. Less than
a year later, Fendler wrote: **Of flowering plants
I have about 1,850 species, although my search
after these may be called but a superficial one. I
think from 800-1,000 more species might be col-
lected and of ferns perhaps from 80-100 more"
[Fendler to Gray, 25 November 1855]. In addi-
tion to ferns and angiosperms, Fendler collected
fungi for M. A. Curtis, a mycologist in the Caro-
linas, lichens for Professor E. Tuckerman, a li-
chenologist at Amherst College, and mosses for
William Starling Sullivant, a distinguished Ameri-
can bryologist in Ohio.
In 1857, after collecting in Colonia Tovar for
over two years, Fendler found it increasingly dif-
ficult to find novel species. “In coming to a new
country it is at first comparatively easy to make
a living by collecting plants; for the collector can
make use of all the different species that meet his
eye, and can carry them home without the aid of
other hired persons or beasts of burden. But after
he has explored the neighborhood and is obliged
to make extensive excursions of from 8-14 days
or 3 weeks, the case is different, and he soon finds
that his earnings do not come up to his expenses"
[Fendler to Gray, 1 July 1857].
After collecting thoroughly around Colonia To-
var, Fendler took longer excursions crossing *'the
principal mountain chain in three different places.
One from Maracai to Columbia [Puerto Colombia ]
to the very margin of the sea; the other from
Valencia to San Estevan within 3 miles of Puerto
Cabello; the third from Petaquire to within a few
miles of the sea-shore. The two first regions are
W est, the third one East of Colonia Tovar. Besides
these I have made a number of minor excursions
into the neighboring valleys” [Fendler to Gray, 1
July 1857]. During these long excursions he re-
flected: “The more I attempt to explore these re-
gions the more am I convinced, that a great deal
remains yet to be done with regard to discovering
and making known the plants of this country. These
extensive ranges of mountains with their innumer-
able recesses and deep ravines, covered with the
densest growth of primeval forest uninterrupted for
more than 150 miles from East to West, have been
in most places never been traversed by civilized
men. When standing on some high mountain-peak
and looking over a part of this territory, it needs
no great power of imagination to be filled with a
longing and an ardent desire to embark in enter-
prises even of the most perilous kinds, in order to
penetrate the unknown abysses and to bring to
light the hidden treasures of vegetation. And when
in such moments I compare my strength and m
fast waning pecuniary means, which forbid to hire
316
Annals of the
Missouri Botanical Garden
a companion to help me carry the burden, then I
feel somewhat akin to depression of mind which
prompts me to leave the spot and retrace my steps
homewards.”
Because Fendler viewed plant collecting as a
business, he was very concerned with the market-
ability of his specimens, which were valued ac-
cording to their origin, rarity, and completeness of
identifications. Thus Fendler wished to have his
plant collections be as rare as possible, as well as
to have them determined. He was concerned that
Karl Moritz, who had been living in Colonia Tovar
for over ten years, would begin again to collect
plants in his territory. “The present letter is chiefly
written to make you acquainted with my intentions
of sending the collections as soon as possible, that
you may be enabled to correspond or to publish
something to that account and secure me from 10-
13 subscribers in time, because Mr. Moritz, who
is still here has sometime ago commenced again to
collect ferns, which he intends to send at an early
date to Germany (I think to Berlin). I have seen
Moritz's own set of his former collections when he
used to travel about the greater part of Venezuela
viz: the Orinoco, the mountains of Merida, Cu-
mana, Caripe and a great many other regions; but
the number of all his species of ferns will hardly
exceed 250 or 260, while I have already 314, of
which at least 290 are collected at the Colony or
from 4-8 miles around it. There are several regions
not far-off, where I never yet have been and which
promise a very rich harvest of new species. I think
I could augment the number of species considerably
and discover many more new ones if | am sure
that they find a market on which I may rely. I am
therefore anxious to secure subscribers for them;
so that I need not fear competition and then I shall
go at it with renewed vigour; and if my life and
health be spared I think of bringing together a
rather complete representation of the vegetation
of this and other parts of Venezuela. When I came
here, Moritz seemed rather surprised that I should
go at collecting plants in a place which he thought
of being thoroughly ransacked, and he said that it
would be a hard matter to find any new species.
He seems however to have altered his opinion in
this respect, after I had been in the field for some
time; for I showed him many a plant which was
new to him” [Fendler to Gray, 25 November
1855]. Fendler’s Venezuelan collections surpass
Moritz’s in quantity and quality (J. A. Steyermark,
pers. comm.; A. R. Smith, pers. comm.).
Plant collecting, however, was not profitable
enough for Fendler to support himself and his in-
valid brother. “Whenever I was engaged in sci-
entific pursuits for any length of time I was soon
obliged to go to work at some other more profitable
business, although that business might not be in
accordance with my inclinations. And now I find
again that the little capital, which I had earned at
Memphis during three years by distilling cam-
phene, is rapidly vanishing, notwithstanding the
most frugal mode of living. I am therefore under
necessity to try my hand for a while at something
else beside collecting plants, and have already com-
menced to make experiments in brewing beer and
making brandy; and shall be obliged (with regret
do I say it), to spend most of my time behind the
still . . . . By no means do I wish by the preceeding
lines to convey to you the idea, that I am dis-
couraged or that I have given up collecting plants.
As long as strength and life and a few spare dollars
remain with me I shall continue to do all I can for
my favorite pursuit; and even now, whenever time
and circumstances allow me to do so, I shall do it
with the same zeal as I have done heretofore"
[Fendler to Gray, 1 July 1857].
FENDLER'S COLLECTIONS
In Venezuela Fendler collected under two num-
ber series, one for the ferns beginning at no. 1 and
ending at no. 500, and one for flowering plants,
numbers 1-2,630. Sets of Fendler's Venezuela
plants were purchased by the following people and
institutions (the number before the name indicates
which set went to that recipient). (2) Hooker (K),
(3) Grisebach (GOET), (4) A. Gray (GH), (5) En-
gelmann (MO), (6) Short (PH), (7) Charles Wyville
Thomson (E), (8) Boissier (G), (9) De Candolle (G),
(10) Oxford herbarium (OXF), (11) Harvey (TCD),
(12) Delessert (C), (13) Martius (BR), (17) Eaton
(YU), (18) Miss Elizabeth Morriss (?PHA), (21)
Eaton (YU). It is not known whether sets 14-16
were sold at a later date, or whether they remained
at GH. Sets 2-13 included ferns and phanerogams;
sets 17-23 consisted only of ferns. The first and
most complete set was retained by Fendler at first.
Later he sold this first set of angiosperms to Gray.
"My full set of Venezuelan plants contained over
twice as many species as set No. 4, and therefore
I hope that by the addition of those plants your
herbarium would gain something. 1 would rather
see them incorporated with your herbarium than
with that of anyone else. The naming of the price
of the lot I leave to you as you can judge best of
their value, and I know that I am in good hands
when I am in yours" [Fendler to Gray, 28 October

1863, St. Louis]. Ten cents per sheet was the usual
asking price, although it was slightly higher for the
orchids since they were often unicates.
At times Fendler felt he was not justly compen-
sated for his specimens. For example, Lindley
thought the price too high. “If Dr. Lindley was
advised to pay but £2 per 100 for my Orchidae,
then I will ask nothing more, and he shall be very
welcome to them if he finds them to be worth that
much. But if on the contrary he finds that the
greater part of them, from being common things,
are of no use to him, which I am inclined to infer
from his letter, then I should be very sorry indeed
that I ever offered them to him. To me that would
be at least objects of remembrance of the amount
of labor, bestowed upon, and perhaps of an over-
animated enthusiasm in searching for them” [Fen-
dler to Gray, 27 March 1859, St. Louis ].
FENDLER's FIELD NOTEBOOK
In 1859, Fendler sent Gray the field notes for
his Venezuelan plants, retaining the information
only on his personal set of specimens (set No. 1)
[Fendler to Gray, 15 December 1859, St. Louis].
The field notes contain all dates and localities from
which a particular species was collected, as well as
elevation and notes about habit. Fendler numbered
his plant collections according to the classification
schemes presented in Gray's Botany of the North-
Map of the localities in northern Venezuela where A. Fendler collected in 1854-1858.
ern United States and Lindley's Vegetable King-
dom rather than the order in which they were
collected, as is usually done today.
o obtain more complete sets of specimens, which
could then be sold at a higher price, Fendler often
applied the same number to specimens he believed
to be the same species but were from widely distant
localities. Fendler also attributed to the same col-
lection number specimens collected on as many as
five different dates. This was a common practice
among professional plant collectors, particularly
those working with Gray (Ewan, 1969), and a
source of problems for plant systematists. The /n-
ternational Code of Botanical Nomenclature
(Burdet et al., 1983) states that an “isotype is any
duplicate (part of a single gathering made by a
collector at one time) of the holotype.” Since Fen-
dler did not indicate on his specimens what specific
date a particular sheet was collected, technically
o isotypes can be designated. Of the 225 names
in this list, 66 were collected on more than one
date. Few taxonomists have previously been aware
of this problem with the Fendler Venezuelan col-
lections.

A. Fendler 1845-5” at the bottom. The collection
number is usually on the label, although it occa-
sionally is on a slip of paper attached to the plant.
Apparently Gray had these labels printed as he did
for Wright’s Cuban collections. Only the first set
of Fendler’s specimens, now at GH, has any col-
lection data on them. Although the labels indicate
that the sets were collected near Colonia Tovar in
the state of Aragua, they were in fact also collected
in the state of Carabobo and in the Distrito Federal.
Figure 3 maps the Fendler localities in northern
Venezuela, and Table 1 presents a list of these
localities.
TYPE LIST
Of Fendler’s 2,630. Venezuelan angiosperm col-
lections, this study located records of 225 that
have been designated as types. Since only the first
of the 20 sets has collection data, full localities
from the notebook are given for these types. In
the following annotated list of angiosperm types
based on Fendler Venezuelan collections, the num-
ber in the parentheses refers to the number of
dates listed in the notebook. The orchids, numbers
1,359-1,489 and 2,124-2,155, were not includ-
ed in the notebook.
The species names listed in Appendix I were
gleaned mostly from the Flora de Venezuela and
the Catálogo de La Flora Venezolana (Pittier et
al., 1945-1947), as well as with the help of several
specialists (see Appendix I). The current accepted
names are given when known to me. Herbaria data
were gathered from the original descriptions, the
TROPICOS data base at MO, the specialists listed
in Appendix I, and the author's search through the
Volume 76, Number 1
1989
Todzia 319
Fendler's Venezuelan
Plant Collections
MO herbarium. Unfortunately, there is no record
of the number of duplicates made of each collection
number (although the number may be on the labels
of set No. 1 at GH, as with the ferns (Smith &
Todzia, 1989), and therefore there is no way to
ascertain which specific specimens are at any one
herbarium. Since GH received Fendler's first set
of angiosperms, excluding the orchids which went
to Lindley, there are probably specimens for all
numbers there. However, only herbaria where a
specimen is confirmed to be deposited are included
in the list. Overall, Fendler's Venezuelan specimens
are widely distributed in the United States and
Europe. The following 18 herbaria are known to
have some Fendler Venezuelan collections (Lan-
jouw & Stafleu, 1957; pers. obs.): AMES, BR,
BUF, C, CM, F, G, G-DC, GH, GOET, K, MO,
NY, OXF, P, PH, S, and US.

Augustus Fendler collected in northern Vene-
zuela between 1854 and 1858, where he amassed
important collections of angiosperms, ferns, fern
allies, lichens, mosses, liverworts, and fungi. Al-
though a general account of his Venezuelan col-
lecting is given in the previous paper (Todzia, 1989),
this article deals specifically with his fern collec-
tions. Fendler’s pteridophyte collections are note-
worthy because they represent the first intensive
gathering of ferns and fern allies from the Coastal
Cordillera of Venezuela, and because they are widely
distributed. Consequently, they have become type
specimens of a great many fern species. The fol-
lowing account has been assembled with the aid of
Fendler’s correspondence with Daniel C. Eaton and
Asa Gray, at the YU and GH archives, respec-
tively.
Fendler’s Venezuelan fern collections as well as
his sets of flowering plants were distributed by Asa
Gray. As with the angiosperms, Fendler initially
retained the first set for himself. In 1859 he re-
ceived a request from Thomas Moore of the Chel-
sea Botanic Garden for a set, but since Moore had
access to William Hooker’s herbarium containing
set 2, Fendler decided to sell his first set to Daniel
C. Eaton, who was then a student of Gray. He did
this because Eaton agreed to publish a list of these
collections, and because the collections would then
remain in the United States, where Fendler would
have easy access to them. In a letter to Eaton,
Fendler stated, “The only set remaining with me
is set No. 1 which I used for comparison and in
which I felt a pride and a pleasure to lay up not
only the most complete but also the finest speci-
mens selected from the rest. There was a time
when I thought I could never part with these plants.
In bringing them up from their hidden places I
have neither shun danger nor travelling expenses,
and it was chiefly the search after Ferns, whic
induced me to cross the principal chain of the
cordillera of the coast upon four different tracks.
I therefore need not say how dear they are to me,
and I never would have sold them to anyone except
to a Botanist, who is able to make the proper use
of them" [Fendler to Eaton, 24 January 1859,
St. Louis]. Fendler went on to say, *For my part
I have neither the necessary books, time, nor her-
barium to do it. Great resources undoubtedly are
necessary to determine, which of the species are
new and which are not; for I have reason to believe
that in works on Ferns, with many species, a critical
and patient overhauling is very desirable, in order
to disperse the existing confusion. | remember to
have seen in one herbarium the same species under
four different names, one of these specimens was
even disposed of under a new genus” [Fendler to
Eaton, 24 January 1859, St. Louis]. In total,
Fendler sent Eaton close to 500 collection numbers

Fern Collections

In 1860, Eaton was Ea a Bachelor of
Science degree from Harvard University for his
dissertation enumerating Fendler's Venezuelan fern
collections along with those collected by Wright in
Cuba, and a few collections of Schott and Hayes
from Panama and Colombia. A year later, Eaton's
dissertation was published (Eaton, 1861). Fendler,
however, was not pleased with this work. In the
following long passage, we can see what a keen
observer Fendler was. “In regard to Mr. Eaton’s
Filices I am sorry to say that I was very much
disappointed. Being in possession of the names of
Dr. Engelmann's set of ferns as determined by
Prof. Mettenius,* I was able to compare them with
those given by Eaton and find that the names of
146 sp. agree with those determined by Mettenius,
while the names of 101 spec. disagree. I am not
able to say who is in the right, but should be inclined
to depend more upon the one that has the longest
experience in the matter [Mettenius J. Such differ-
ences of different authors are most discouraging
to the student of botany and a severe drawback in
the acquisition of knowledge. But what concerns
me more immediately and of which I think I have
reason to be solicitous, is the readiness with which
Mr. Eaton throws different, quite distinct, species
under one and the same name. I regret this, the
more it may be inferred as if I purposely manu-
factured species for the sake of selling one and the
same species over again under different numbers.
Having pointed out in Mr. Eaton's set some of the
more obscure characters of many species very
much resembling each other, I thought I had done
something to prevent mistakes. It always seemed
to me, that authors who only see 1 or 2 dried
specimens of each species ought to pay at least
some slight regard to the opinion of a collector who
had the best opportunities, and for 4 years availed
himself of those opportunities to study the habits
of the different ferns, and to observe them in their
growing state in the different phases of their growth,
not on single specimens or in single localities only,
but in hundreds of different places and individuals."
Fendler continued: “There may be a dozen species
about which I was rather doubtful, but all the rest
I consider genuine species; and as soon as I shall
have time to examine Dr. Engelmann's set, I shall
endeavor to point out the differences in species
considered the same by Mr. Eaton. That even the

ogist, ie fern herbarium is now mostly
most experient [sic] authors on ferns may some-
times take 2 different species to be one and the
same is proved by Prof. Mettenius calling No. 161
'a young specimen of 162.' Now the former (No.
161) is not only different in form but has also 2
to 3 oval tubers, all the fronds die at a certain
season of the year, and new fronds make their
appearance rather suddenly but not before the
commencement of the rainy season; the latter (No.
162) is a perennial plant to be seen at all times of
the year and never possessing tubers” [Fendler to
Gray, 24 March 1868, St. Louis]. In fact, these
two numbers do represent two species (Appendix
I), and Fendler was correct.
Nevertheless, Fendler's friendship with Eaton
grew, as evidenced by Fendler's 15 letters to Eaton
written from Trinidad between 1878 and Fendler's
death in 1883. In Trinidad, as in Venezuela, he
seems to have been preoccupied with collecting
ferns and seems to have particularly relished dis-
cussing his Trinidad fern collections with Eaton.
Fendler, however, much preferred Venezuela over
Trinidad and in his letters to Eaton, Engelmann,
and Gray from Trinidad, he often mentioned how
much he would like to return to Colonia Tovar. In
his last letter to Eaton before his death, Fendler
stated, “I long for the cool alpine air (damp though
it be) for the deep shades and the eternal silence
of those primeval forests, where a quarter of cen-
tury ago my footsteps were wandering in search
of the treasures of botany—especially those of
ferns—again to go and see them, and to draw them
forth from out their hiding places in the deep dells,
or to bring them down from the mountain's high
summit” [Fendler to Eaton, 15 June 1882, Port-
of-Spain, Trinidad]. At 69, forever the fervent
collector, Fendler asked Eaton if the professor could
find subscribers to about 40 sets of Venezuelan
ferns [Fendler to Eaton, 15 June 1882, Port-of-
Spain, Trinidad]. Fendler often wrote to his cor-
respondents that he longed to return to the “land
of perpetual peace ... the happy region of the
ferns."
FENDLER'S FERN NOTEBOOK AND COLLECTIONS
Fendler's field notebook in the GH archives is
not chronological and consecutive, but rather a
catalog of species in taxonomic order. Thus, the
number sequence begins with 1 (Marattiaceae),
proceeds through the more primitive fern families
(Osmundaceae, Schizaeaceae, Hymenophyllaceae,
Gleicheniaceae, Cyatheaceae), and then continues
with the more advanced ferns, genus by genus, up
to number 324. Numbers after 324 were collected
Annals of the
Missouri Botanical Garden
after a trip to the United States and after he had
distributed some of his material. It is obvious that
the notebook was compiled after many of the col-
lections had already been made and put into se-
quence. Fendler combined collections made on dif-
ferent dates and at different places under a single
number. For example, Fendler 6, Anemia villosa,
was collected on nine different dates (according to
data on the sheet at YU) and most likely at several
different localities during the years 1854, 1855,
and 1856.
Fendler probably revisited many collection sites
in an attempt to amass additional material of a
given number, because he intended to collect in
large sets for sale to as many individuals or herbaria
as possible. It appears that he tried to collect in
sets of 20, although he gathered 40 sheets of
Fendler 23, Trichomanes reptans. 'The number
of collections appears in the upper right-hand cor-
ner of the labels on sheets at YU but does not
appear on the labels of Fendler collections in other
herbaria. In some cases, Fendler kept an account
of material of varying stages, e.g., he collected 26
young and 12 old specimens of Marattia laevis
(Fendler 3). In other instances, he recorded the
number of specimens in different categories, e.g.,
he collected 20 specimens of no. 94, Paesia glan-
dulosa, and 5 more with the rhizome. For many
numbers through about 324, specimens were col-
lected in rather large sets. Thereafter, the sets were
generally much smaller, often only a few sheets.
Most of the numbers after 324 were gathered in
the years 1855 to 1858, whereas most collections
of the numbers before 325 were made in 1854,
with additions to the set made in 1855 and 1856.
Fendler's keen eye is evident by the fact that,
even though he often collected the same species
(or number) at different times and/or localities,
there are very few mixed gatherings. He must have
had a very discriminating eye for differences. When
in doubt, he often gave aberrant collections Greek
letter designations a and 8 under the same number,
or labeled the additions “ad 56”; sometimes these
represent noteworthy taxonomic variations (occa-
sionally different species), sometimes only forms of
little taxonomic significance. The following are tax-
onomically mixed collections: 16, 31, 64, 72, 73,
83, 98, 117, 143, 179, 181, 185, 187, 221,
224, 232, 2587, 259, 293, 294, 322, 324, 364,
378, 380, and 473. Some of these probably rep-
resent inadvertent mixing or misnumbering, where-
as others are in large genera of great taxonomic
difficulty, e.g., Elaphoglossum, Thelypteris, and
Selaginella.
Fendler's collection numbers range from 1 to
499. Of these, 44 are thus far identified as types.
We have seen specimens or notebook information
for all numbers except 2 and 339. In addition,
neither we nor Eaton (1861) saw specimens num-
bered 337, 345, 346, 384, 392, 401, 427, 442,
458, 462, 478, 484, or 490. The notebook at
Harvard contains entries for numbers 58 to 499;
inexplicably, the early numbers are missing.
Because Fendler gave the same collection num-
ber to plants collected at different times and lo-
calities, it often is impossible to determine the lo-
cality and date of a particular specimen. In a few
cases there is only a single date on the specimen
and in the notebook. In the list that follows (Ap-
pendix I) dates are given only where there is
reasonable certainty that the entire gathering was
made on a single date at a single place. For those
numbers that were collected on more than one
date, we give the total number of dates (as indicated
from the notebook and on the specimens at YU).
For all numbers, the size of the set, when known,
is given.
Fendler's Venezuelan pteridophytes were widely
distributed, and specimens have been located in
the following 16 herbaria: B, BM, BR, CU, F, G,
GH, GOET, K, MO, NY, P, PH, S, US, and YU.

131761 (holotype, MO, on two sheets,
3472626, 3472627; isotype, UC).
Regio penaria radicum ab cormo 4-5 cm, 4-5 cm
longa. Fotis basalia 6-10, anguste i margi-
rulatis, 45-60 cm longa, 11-18 mm
lata. iin cabe 4 4-5 ramosus. Folia caulina 4-5
longiattenuata. Tepala flava. Filamenta squamata, linear-

Storage region of the roots 4-5 cm from the
corm, 4—5 cm long. Basal leaves 6-10, ascending,
narrowly lanceolate above the base, bases persis-
tent as a fibrous collar, minutely denticulate-ser-
rulate, usually 45-60 cm long and 11-18 mm
wide. Scape glabrous, 98-118 cm high, 5-branched.
ANN. Missouni Bor. Garb. 76: 350. 1989.
Cauline leaves 4-5, long-attenuate. Tepals yellow,
ca. 10 mm long. Filaments minutely to noticeably
scaled, linear, 6.5 mm long. Anthers free, 2.4-3
mm long, appearing to dehisce laterally. Ovary 2
mm long. capsule broadly oblong, 10-11 mm long,
6.5-7.5 mm wide. Seeds black, colliculose, 2.5-
3 mm across.
Known only from the type locality, this species
is easily distinguished from other yellow-flowered
South American Echeandia species by the com-
bination of scaled filaments, many branches, and
the storage organs developing at some distance
from the corm. It is unusual for yellow-flowered
species to occur at such low elevations.

rutex armatus spinis brevibus validis rectis, foliis ro-
tundis parvis stellato-tomentosis; flores solitari v-geminati,

Slender, branched shrub or tree to 3 m tall;
twigs slender, at first appressed tomentose with
reddish hairs, soon puberulent with reduced buff-
colored trichomes and deeply furrowed, armed with
short, stout-based, puberulent
spines. Leaves mostly paired in fasciculate short-
shoots, entire, rotund, apically rounded, ed
rounded, truncate or cordate, mostly 8-20 m
long, thick, felty with dense short-stalked, elate
hairs, the costa evident, the minor venation o
nearly straight,
scure; peduncles canaliculate adaxially but alten
appearing terete because of the dense tomentum,
mostly 5-10 mm long, with occasional small straight
spines. Inflorescences solitary flowers or paired fas-
cicles from the leafy short-shoots; pedicels resem-
bling the petioles but somewhat longer. Flowers
with calyx ca. 4 mm long, lobed about 44 way
down, the lobes convex, obtuse, tomentose, un-
armed; corolla pale purple, mauve, or white, ca.
10 mm long, lobed 44 way down, tomentose outside
except on the membranaceous inter-lobe fringing
areas, glabrous within, the nervature drying con-
spicuous within; stamens 5, equal, the anthers yel-
low, slender, 5 mm long, opening by minute ter-
minal pores; ovary glabrous, drying somewhat lobed,
the style slender, exserted slightly beyond the sta-
mens, with a few short, gland-tipped simple hairs
near the base. Berry green, juicy, 4-lobed, ca. 5
mm diam., entirely but loosely enveloped in the
calyx, the spiny, accrescent calyx echinoid, subglo-
ANN.
seeds (Descoings 2375)
compressed, dark, 2.5 mm long
bose, ca. 2 cm diam.;
At time of flowering the calyx of this species is
devoid of spines, in contrast to its copiously spiny,
echinoid condition when in fruit.
Collections of this species were first confused
with Solanum dubium Fresen of Ethiopia, which
has similar spiny accrescent calyces, but that species
is herbaceous and has much larger, lobed leaves.
The species described here differs from the other
two arborescent species of southwestern Madagas-
car in its accrescent, spiny calyx and in its rotund,
concolorous leaves. Solanum toliaraea is sympat-
ric, at least in part, with other arborescent sola-
nums, S. bummeliifolium Dunal and S. heineanum
D'Arcy & Keating, which differ in usually spineless
calyces and porrect, scutellate hairs.
Solanum toliaraea was seen as scattered indi-
viduals in didieriad woodlands of southwestern
Madagascar. Most collections were made from
plants growing on sand near the coast just north
of the major city of Tulear and hence just north
of the Tropic of Capricorn.
The name toliaraea is derived from the Mala-
gasy spelling for the city of Tulear.

NOTE CONCERNING
FESTUCA HENRIQUESII
(GRAMINEAE) IN
NORTHERN PORTUGAL
The species Festuca henriquesii Hackel (Gra-
mineae), first described in 1883, is endemic to
Portugal. In various floras and subsequent publi-
cations, namely Coutinho (1939), Sampaio (1946),
Litardiére (1952), and Tutin et al. (1980), the
location of this species has been given as restricted
solely to the Serra da Estrela, a mountain range
in northeastern Portugal. Little information is avail-
able concerning its ecology, except that specimens
have generally been collected from high places in
this mountain range.
Recently, however, I recorded this species from
a grassland area in the Serra do Gerés, in northern
Portugal (Hale, in press). I had believed that this
was the first record for the species outside of the
Serra da Estrela range. The location, in grazed
grassland within an area generally of ericaceous
shrubland, is known as ““Lagoas” because of two
small nearby lakes. The plants were growing on
an acid soil over granitic parent material at an
altitude of 1,150 m (grid reference X326 071;
Carta Militar 31).
Further investigation revealed, however, that
this record for the species in the Serra do Gerés
was not unique. Besides two records from the Serra
da Estrela, three specimens of F. henriquesii exist
in the Herbarium of the Institute of Botany “Dr.
Gonçalo Sampaio” in Porto, collected from the
Serra do Gerés and nearby areas (Table 1). Despite
the existence of these specimens, however, this
species appears not to have been previously re-
ported from these mountain ranges.
It is clear from these records that Festuca hen-
riquesii is not restricted to the Serra da Estrela;
the range includes the serras of Gerés, Peneda,
and Barroso. The species might be a glacial relict
rined to a few mountain ranges and not noticed
ide of the Serra da Estrela; alternatively,
its dictation may be expanding. In view of the
apparently discontinuous distribution, these other
mountain ranges being nearly 200 km from that
TABLE 1. F. henriquesii records outside Estrela.

of Estrela, it is quite possible that the species might
turn up in other intervening mountain ranges in
the north of Portugal.
I thank the staff of the Herbarium of the In-
stitute of Botany “Dr. Gonçalo Sampaio,” Porto,
for confirming the identification of the “Lagoas”
specimen and for access to the previous records
of the species.

PASSIFLORA CITRINA,
A NEW SPECIES IN
SECTION XEROGONA
(PASSIFLORACEAE),
FROM MESOAMERICA
The center of diversity for Passiflora L. subg.
Plectostemma Masters sect. Xerogona (Raf.) Killip
is in northern Central America, where at least six
species occur in Guatemala alone. The section is
notable in the genus Passiflora for its unusual
capsular fruit. Killip (1922, 1924, 1927) described
five species of this section from Central America
and southern Mexico that had been confused with
P. rubra L. or P. capsularis L. Newly described
here is the yellow-flowered P. citrina, yet another
member of this section that has been hidden under
misapplication of the name P. capsularis.

Passiflora citrina may be referred to subg.
Plectostemma sect. Xerogona because of the sub-
pentangular stem, absence of petiolar or laminar
nectaries, absence or near absence of floral bracts,
elongate fruits with six "keels, and seeds with a
transversely grooved sclerotesta having a chalazal
eak that is sharply angled towards the raphe.
Mature fruits are unknown; however, a fruit that
is probably of full size with nearly mature seeds is
found on the isotype at NY. On a different collec-
tion, Howard et al. 637, the collector observed
the fruits to be “red,” but no fruits are included
with the specimens. It is unknown whether the fruit

of this species is six-valvately dehiscent, as is usual
in the other members of sect. Xerogona.
Passiflora citrina is remarkable for its elongate
yellow flowers that are tubular in the basal half.
The androgynophore is distinctively long and sets
the species apart from all other members of sect.
Xerogona except P. sanguinolenta Masters from
southern Ecuador. Though very similar to P. ci-
trina, P. sanguinolenta has nearly triangular stems,
peduncles solitary at the nodes, pink to purplish
red flowers that retain a diminutive second series
of coronal filaments, and seeds with slightly ru-
gulose ridges. Both species have slightly elongate
flowers of similar morphology, flowers that have
departed from the usual bowl-shaped hymenopter-
an-adapted groundplan in sect. Xerogona (Lind-
man, 1906) by reduction and fusion of the coronal
filaments and partial connation and adnation of the
perianth. In P. citrina the sepals are free from
each other to within 2-6 mm of their bases, but
they are submarginally adnate to the edges of the
petals; the petals, in turn, are adnate to the connate
portion of the coronal filaments. The net effect is
a cylindrical structure formed by the adnation of
the basal half of the perianth to the tubular and
basally connate coronal filaments. The coronal fil-
aments are free only in the distal 3-6 mm and are
usually not visible on herbarium sheets without
dissection. In dissected and living specimens, I could
detect no trace of a second series of coronal fila-
ments near the operculum.
The derived floral morphology of P. sanguin-
olenta is related to a shift in pollinators: the species
is primarily hummingbird pollinated in its native
habitat (C. Hofmann, pers. comm.). It is probable
that P. citrina has also shifted away from polli-
nation by hymenopterans.
The butterfly Heliconius charitonius was ob-
served using MacDougal et al. 3048 as a host
lant.
Floral bracts are fundamentally absent in P.
citrina, but in Molina 6510 the peduncles occa-
sionally bear a single bract at the apex.
This species was first identified as undescribed
while the author was a National Science Foundation
Fellow at Duke University, and I gratefully ac-
knowledge the financial support of the NSF, the
assistance of the curators from the herbaria cited

A NEW SPECIES OF
STRYPHNODENDRON
(FABACEAE: MIMOSOIDEAE)
FROM AMAZONIAN ECUADOR
Stryphnodendron Mart. (Fabaceae: Mimoso-
ideae) is a genus of 25 known species, primarily
Brazilian in distribution. It is well represented in
Amazonia by forest trees and in the Brazilian cer-
rado region by shrubby species (Occhioni Martins,
1974, 1981; Occhioni, in prep.). Recent collec-
tions by the senior author and associates in eastern
Ecuador, in the course of fieldwork for a floristic
study of the trees of the region, have revealed a
new species of Stryphnodendron at the western
edge of the Amazon basin and in the adjacent
foothills of the Andes.

Notes 359
Stryphnodendron porcatum is probably most
closely allied with S. guianense (Aubl.) Benth. subsp.
glandulosum Forero, known from Peru, Bolivia,
and Amazonia in western Brazil, which has similar
pubescence of foliage, including the tuft of hairs
near the base of the blade, and densely pilose ovary.
In S. guianense subsp. glandulosum, however,
the calyx and corolla are short-puberulent exter-
nally, whereas in 5. porcatum the calyx and corolla
lobes are densely pubescent with longer, golden
hairs, while the corolla tube is nearly glabrous with
scattered golden hairs. The typical subspecies of
S. guianense, which ranges widely in Amazonia
and the Guianas, lacks the tuft of hairs at the base
of the leaflet blades, and all floral parts are glabrous.
e most distinctive feature of 5. porcatum,
which readily separates it from all other species in
the genus, is the striking ornamentation of the
legume, an irregular chevron-like pattern of ridges
on the surface of the valves. The specific epithet
refers to this sculptured surface of the fruits (Latin
orca — *'ridge between two furrows made in plow-
ing”; Stearn, 1966).
Some individuals of S. porcatum are evidently
female-sterile; the flowers of Palacios 1369 com-
pletely lack pistils.
To our knowledge, this is the first published
report of the genus Stryphnodendron for Ecuador.
No other species are known to occur sympatrically
with S. porcatum in the Amazon region of the
country.
Stryphnodendron porcatum occurs on rich silty
alluvial soils of river floodplains, and in Amazonian
Ecuador, on upland Oxisol hills up to 1,500 m on
the lower slopes of the Andes. In primary forest it
attains a height of 40 m with a diameter at breast
height of 70 cm. In the region around Coca, Napo
Province, Ecuador, 5. porcatum is also frequent
in secondary forests and is often left in pastures
after the surrounding forest is cut.
The sweet pulp surrounding the seeds is similar
to that of Prosopis and Gleditsia. Several trees at
the INIAP-Payamino agricultural experiment sta-
tion near Coca stand in experimental pastures es-
tablished for raising tropical hair sheep. The sheep
eat with great relish the Stryphnodendron pods
that fall to the ground, apparently attracted by the
sweet pulp. The new species therefore shows some
promise for inclusion in agronomic trials as part of
the agroforestry and silvo-pastoral production sys-
tems involving sheep, pastures, and forage legumes
now being developed for and implemented by set-
tlers in the Napo region of Ecuador.
The support of the U.S. Agency for International
Development (USAID) and the Forestry Director-
ate of the Ecuadorian Ministry of Agriculture, for
the research in eastern Ecuador, is gratefully ac-
knowledged. The authors thank Enrique Forero for
bringing us together through correspondence, and
Alejandro Suárez for preparing the illustration.

A NEW SPECIES OF
HYBANTHUS (VIOLACEAE)
FROM PANAMA
Hybanthus is a very poorly known genus of
150 species of herbs, trees, and shrubs from the
Old and New World. The last synopsis of the genus
throughout its range enumerated 32 species in the
New World (Melchior, 1925); Morton (1944) pro-
vided the most recent synopsis of the Central Amer-
ican species. The new species proposed here, Hy-
banthus jefensis, is clearly distinct from all species
in Central America and is not placed within any
species presently known from Colombia (Smith &
Fernández-Pérez, 1954).

This species is distinctive by virtue of its small
crenulate leaves with red dots and punctations when
dried; axillary inflorescences fasciculate on short
shoots ca. 2 mm long; stipules that are chartaceous
when dry; and pedicels 1-2 mm long. The anterior
petal, one of the most diagnostic characters of the
genus, is pandurate, 0.7-1 cm long, and rounded
apically. In southern Central America H. jefensis
appears to be most similar to H. guanacastensis
Standley from which the new species differs by its
chartaceous (vs. indurate) stipules, crenulate (vs.
doubly serrate) leaf margins, shorter anterior petals
(0.7-1 cm long vs. ca. 1.2 cm long), and smaller
capsules (0.7-0.8 cm long vs. 1.5-2 cm long).

Morphological, Autecological and Systematic
Studies in Angiosperms is an important addition
to the increasing botanical literature of high sci-
entific quality being produced in Latin America. It
has been published by the Colombian Academy of
Sciences as the first volume of a new series called
“Serie Jorge Alvarez Lleras.” The actual text is
188 pages long, with 75 figures, including several
color photographs, and a bibliography with over
90 citations. The text is divided into two parts.
The first part deals with the morphological and
autecological studies and includes five chapters (1—
5), while the second deals with the systematic stud-
ies and is made up of one chapter (6).
The author indicates that one of his objectives
is to present to a broader audience the “typolog-
ical method, which has been developed in Ger-
many but is not well known among Spanish- and
English-speaking phytomorphologists. In the first
chapter he discusses the general principles of the
typological method, including such concepts as ho-
mology, position, continuity, similarity, etc.; the
procedures employed in the study of specific prob-
lems; the contribution of typology to our under-
standing of the organization and architecture of
the angiosperms; and the relationship of typology
with taxonomy and phylogeny. In Chapter 2, the
typological theory and its relation to the evolution
of the inflorescence is discussed. Chapter 3 deals
with new concepts developed by the author on the
diversity and evolution of organizational patterns
found in the floral meristems in angiosperms, based
on his observations of a number of families, in-
cluding Melastomataceae, Araliaceae, Bignoni-
aceae, Asteraceae, Cyperaceae, Juncaceae, Po-
aceae, Bromeliaceae, and Scheuchzeriaceae.
Chapters 4 and 5 deal with the author's original
typological studies in Lilaea, Triglochin, and
Scheuchzeria, which include the study of the ar-
chitecture of the meristem and its correlation with
the reproductive strategies of these plant groups.
In Chapter 6, Mora-Osejo gives an example of the
applicability of the typological method to the taxo-
nomic study of Oreobolus R. Br., a genus of Cy-
peraceae.
There are several aspects of this publication that
I find outstanding, the most important being the
thorough discussion of the theory and practice of
the typological method. The author explains how
this method allows for a comparative analysis of
architectural patterns in plants as opposed to a
purely descriptive analysis. The method also allows
for interpretation of information derived from the
detailed analysis of plant structures through the
understanding of the interconnections among them.
At the same time, it provides valuable tools for
understanding adaptations to the environment as
well as reproductive strategies in angiosperms.
Aside from its obvious scientific value, the reader
is also very favorably impressed by the good quality
of the printed product and by the quantity and
quality of the illustrations, which include numerous
schematic representations, color and black and white
photographs, details of plant parts, and more.
The volume is a substantial contribution to our
understanding of this important subject, as are most
of Professor Mora-Osejo's publications. His study
of the biology of the Haloragaceae, published as
part of his treatment of the family for the Flora
de Colombia, is another example of his scientific
excellence. It is to be expected that this volume
will be given proper consideration by phytomor-
phologists in the United States and in Latin Amer-
ica. Its contents are well worth careful study. This
work is the result of many years of careful research
by one of Latin America's most prominent scien-
tists.— Enrique Forero, Missouri Botanical Gar-

NOTICES
THE 1988 Jesse M. GREENMAN AWARD
The 1988 Jesse M. Greenman Award has been
won by John H. Wiersema for his publication “A
Monograph of Nymphaea Subgenus Hydrocallis
(Nymphaeaceae)," which appeared in Systematic
Botany Monographs, volume 16. This monograph
is derived from a Ph.D. dissertation submitted to
the University of Alabama, under the direction of
Dr. Robert R. Haynes. Dr. Wiersema based his
classification on numerical taxonomy, scanning
electron microscopy of seeds and pollen, chro-
mosome numbers, floral biology, artificial hybrid-
ization, flavonoid chemistry, and general mor-
phology. Fourteen species are recognized in the
subgenus, which is restricted to the American trop-
ics and subtropics, and one new subspecies is pro-
posed.
This Award is named for Jesse More Greenman
(1867-1951), who was curator of the Missouri
Botanical Garden Herbarium from 1919 until 1943.
A cash prize of $250 is presented each year by
the Garden, recognizing the paper judged best in
vascular plant or bryophyte systematics based on
a doctoral dissertation that was published during
the previous year.
Nominations for papers published during 1988
are now being accepted for the 21st annual award,
which will be presented in the summer of 1989.
Reprints of such papers should be sent to: Green-
man Award Committee, Research Division, Mis-
souri Botanical Garden, P.O. Box 299, St. Louis,
Missouri 63166-0299, U.S.A. In order to be con-
sidered for the 1989 award, reprints must be re-
ceived by June 1, 1989.

NEW SPECIES AND
COMBINATIONS IN TROPICAL
AMERICAN POLYSTICHUM
(DRYOPTERIDACEAE)
David S. Barrington?
ABSTRACT
A taxonomic history for the fern genus Polystichum in Latin America and an analysis of the vi dein characters
at the species level in the genus provide the context for the recognition of new and overlooked taxa. Three new
species are described from Latin America, and a new combination is provided for a Polystichum species from the
southern Andes
In the course of preparing a treatment of the
genus Polystichum for the Flora Mesoamericana,
I have discerned a set of new and neglected species
from Central America and the northern Andes,
which I report here. The species now included in
the genus Polystichum have only once been in-
cluded in a monograph (Mettenius, 1858); there
has been no modern monographic work on the
genus in the New World. An inquiry into species
and speciation phenomena in Costa Rica (Barring-
ton, 1985a, b; Barrington, et al., 1986) has led
in turn to an inquiry into the significance of hybrids
with respect to species concepts in the ferns (Bar-
rington et al., in press). I report here on the mor-
phological characters important in distinguishing
species of Latin American Polystichum. This re-
view of characters provides the context for the
descriptions of species, which make up the central
contribution of this work.
TAXONOMIC HISTORY
The genus Polystichum Roth, terrestrial ferns
characterized by fastigiate leaves with inequilateral
leaf segments and peltate indusia (when present),
is prominent and diverse in montane regions
'T thank Luis Diego Gómez P. for his energy and support of my fieldwork in the Sierra Talamanca, Steven R
Hill for his critical reading of the Latin descriptions, and Lynn Bohs for her thorough review of the manuscript.
Several nomenclatural and taxonomic problems were resolved with Rolla Tryon's help. The curators of the following
herbaria supported this project through loan of materials: A, AA
U, CR, ENCB, F, GH, MO, NY, UC, US, USNA,

throughout the world. The generic name originates
with Roth (1799), but it was K. B. Presl (1836)
who first circumscribed the genus as it is now
recognized. The most important influence on the
taxonomic history of Polystichum was the treat-
ment of W. J. Hooker (1862), in which most of
the twice-pinnate taxa in the world were combined
into one species. As a result, the morphological
and taxonomic diversity of species was left un-
studied by the otherwise productive taxonomists of
the late nineteenth century. Christensen (1906)
maintained Hooker's counterproductive species
concept in Polystichum, which has perpetuated
the tendency for taxonomists to ignore the diversity
of twice-pinnate species. Christensen did recognize
4l forms, many of which were associated with
names whose types represent distinct species.
atin America and eastern Asia are the two
centers of diversity for the genus Polystichum.
Although the diversity and biology of species are
well known in Asia (Tagawa, 1940; Daigobo, 1972),
we know little about the genus in the New World
tropics. Maxon (1909) was the first to recognize
natural species in the American tropics, but his
work was confined to the West Indies. Only re-
cently (A. R. Smith, 1981; Stolze, 1981) has sim-
ilar progress been made in defining the continental
species. In the past few years, the extent of the
taxonomic problem has become clear with the dem-
onstration of extensive hybridization and allopoly-
ploidy in the American tropics (Barrington, 1985a,
" popa et al., 1986). I reviewed the present
mic status of the genus Polystichum in Latin
America (Barrington, 1985c).
MORPHOLOGY
The analysis leading to the descriptions of the
new species provided here and the work on hy-
bridization and polyploidy have revealed the most
useful characters for delineating Polystichum
species in Latin America. Since there has been no
previous morphological review for the genus in the
Neotropics, I provide an analysis of the important
characters for Polystichum. I hav
mented on ontogenetic and environmentally in-
duced variation, which is unusually confusing in
the genus
also com-
INDUMENT
Indument in Polystichum consists entirely of
scales and scale homologs (squamules and micro-
scales); true hairs, bristles, and spines are absent,
at least in Latin American species. The general
form, texture, and frequency of scales are impor-
tant in delineating taxa of Polystichum. Particu-
larly important are histological features of the scales:
they may be conform (sensu Tryon, 1970) or they
may have a margin of cells different in shape and
orientation from the scale body. Scale color is im-
portant too, although variable with position on the
plant and age of the plant. Tagawa (1940) con-
tended that the smallest scales on the abaxial lam-
ina surface (the microscales) are important in de-
fining subgeneric groups in Polystichum. In Latin
America, variation in microscales is extremely con-
servative, consistent with Tagawa's contention. Most
species have the acicular microscales typical of
sect. Metapolystichum
I have followed Smith (1981) in describing the
processes that arise from the edges of scales and
squamules as cilia, although this is an oversimpli-
fication. [n fact, scales and squamules bear a con-
tinuum of processes from cilia (long and delicate)
to setae (short and stiff). I have chosen to call all
of these processes cilia and use adjectives to de-
scribe their length and stiffness. The kinds and
proportions of these cilia on the different scales
and squamules are important taxonomic characters
in Polystichum.
LAMINA
The dissection and texture of the lamina provide
critical characters for distinguishing species of Po-
lystichum, although they are phenotypically and
ontogenetically variable. Particularly confusing is
the tendency for older plants to have larger, more
dissected leaves. Nevertheless, species can be cir-
cumscribed within the context of the ontogenetic
variation encountered. In addition, the shape, angle
of attachment, and revoluteness of leaf segments
(pinnae and pinnules) are all important, although
phenotypically variable (especially revoluteness).
Development of the spinules (extensions of vein
tips) varies among species. The complex interaction
of ontogeny, environment, and genotype that shapes
Polystichum leaves perhaps explains the recog-
nition of large, poorly resolved taxa by both Hooker
and Christensen.
SORI AND SPORANGIA
The placement of the sorus relative to the vein
tips is important in Polystichum, even though it
is variable across a segment. Indusium presence
or absence is an important character, although the
indusium is sometimes pal in ee Po-
lystichum species. In addition, , Shape,
and histology of the inden vary among, but
usually not within, species. Color is sometimes use-

ful but is variable with age. The design of the
perispore is usually constant within species.
Color of the indument is a useful character in
Polystichum, as in many ferns. The color names
used in the descriptions here are the National Bu-
reau of Standards color names as defined in Na-
tional Bureau of Standards Special Publication
440 (and its predecessor, Circular us iir
by comparison of indument with the BS
Color-Name Chart (a supplement to D Special
Publication 440), which is a partial set of color
chips representing the color centroid. I standardize
color terminology in this way, rather than using
the Ridgway-Dade terminology and standardization
(Stearn, 1983), because those color names are
much less familiar, and the color chips on which
they are based are much harder to locate. Indu-
ment is variable and systematically useful in all
three dimensions of the color centroid (hue, value,
and chroma); it is also variable in these dimensions
with position on the plant and age of the individual.
HYBRIDIZATION AND SPECIES
DEFINITION
Hybrids between the new Costa Rican species
described here and several other species were en-
countered during fieldwork. Several of these hy-
brids have been described elsewhere (Barrington,
1985a, b). All of them meet two criteria of hy-
bridity: intermediacy and spore irregularity. Since
all of the hybrids have irregular spores, they are
probably sterile and hence provide evidence of
species-level divergence between their progenitors
(Barrington et al., in press). This evidence provides
a first working hypothesis for species definition in
tropical American Polystichum and the basis for
recognizing the new species described here.

all confined to high-altitude forests. Polystichum
rachichlaena is notable for the large size (over 1
mm diam.) and persistence of its indusia; it also
has petiole scales virtually devoid of cilia. The
lamina and sorus of P. concinnum are similar to
those of P. erythrosorum, but the petiole scales of
P. erythrosorum are er, marginate, and
strongly bicolorous (basally lustrous and black with
brownish orange borders). In addition, the long,
delicate cilia of P. concinnum are lacking in P.
erythrosorum, and the small distal cilia are not
dark and indurated as they are in P. concinnum.
Polystichum concinnum is well represented in her-
baria; it has been determined most often as either
Polystichum muricatum (L.) Fée (which differs in
having short petiole-scale cilia) or Polystichum
ordinatum (Kunze) Liebm. (which differs in having
narrow leaf bases and strongly bicolorous petiole
scales with thick bases).
David B. Lellinger, of the United States National
Herbarium, first distinguished P. concinnum and
coined its species epithet.

Polystichum
correct name of the widespread Latin American
alpine Polystichum commonly known as Polysti-
chum polyphyllum (Presl) Presl.) Polystichum
talamancanum is prominent in rock clefts and on
roadbanks along the Pan-American Highway above
treeline in Costa Rica. It tends to have more patent
pinnae and flat pinnules in shade. The indusia are
variously developed: some sporophytes never have
indusia; others regularly produce spatulate indusia.
This variation complicates discrimination of P. con-
cinnum, P. talamancanum, and their backcross
hybrid.
Polystichum talamancanum, endemic to the
region above treeline in the Sierra Talamanca, may
be confused with Polystichum orbiculatum and
allied taxa. Polystichum orbiculatum in Costa Rica
has flaccid petiole scales that are paler and more
orange than those of P. talamancanum and has
long, delicate cilia throughout. In addition, P. or-
biculatum has apically as well as laterally revolute
pinnules, and it is never indusiate, whereas
talamancanum has pinnules that are revolute only
laterally and sometimes has indusia.
n the Andes from Venezuela to Peru, an array
of plants has been collected from those like P.
orbiculatum in Costa Rica to plants much like P.
talamancanum. The Andean plants most like P.
talamancanum differ from it in lacking indusia
and having broader, larger petiole scales with nar-
row white borders bearing short, stiff cilia; if they
are hybrids, their progenitors differ from those of
P. talamancanum and are best determined as P.
pycnolepis (Kze. ex Kl.) Mett. The taxonomy and
evolution of P. orbiculatum and its allies in the
Andes is a complex and intriguing problem: the
hybrid origin of P. talamancanum on the Sierra
Talamanca is likely to be one part of a much
broader, Andean set of evolutionary events, in-
cluding the origin of P. orbiculatum and other
high-altitude Polystichum species.

diversity of the genus in Latin America may still
be undocumented by collections, in spite of recent
intensive work. This strongly suggests that main-
taining substantial collecting programs in tropical
forests between 2,000 and 4,000 m is a priority
if we are to represent the morphological diversity

forests.

VII. ADDITIONS IN
MAXILLARIA FROM THE
VENEZUELAN GUAYANA'
Germán Carnevali? and Ivón Ramírez?
ABSTRACT
T w Maxillaria species from the Venezuelan Guayana, M. foldatsiana and M. santanae, are described and
illustrated. One highly variable species, M. auyantepuiensis, is discussed, and a new subspecific taxon is proposed.
Maxillaria tenuis is noted as a new record for the Venezuelan flora.
Maxillaria Ruiz & Pavón is the largest genus
of the subtribe Maxillarinae, with about 400-4
species ranging from Mexico and the West Indies
to southern Brazil. The genus reaches its highest
development in the Andes, but le America,
southern Brazil, the Amazonian a and the
Guayanas are well represented. The species of
Maxillaria usually grow in places of heavy rainfall
but often can be found in places with a marked
dry season. They grow in almost every vegetation
association and at any elevation from sea level to
near the snow line but are especially common in
rainforest or cloud forests at 500-2,000 m. Most
members of the genus are epiphytic, but it is not
unusual to find lithophytic or even terrestrial species,
particularly in open, humid places. The vegetative
morphology is very variable, ranging from tiny
plants less than 1 cm high to plants 2 m long.
They are usually pseudobulbous, sympodial plants,
but pseudobulbless, almost monopodial species are
not unknown. Rhizomes may be short, making
caespitose plants, but many species have long
creeping primary stems; these may be appressed
to substrate for their entire lengths or only attached
at their bases to the host, making erect, ascendent,
or pendulous plants
Maxillaria is characterized generically by sol-
itary flowers originating from the pseudobulb base
or from the internodes of the rhizome (the Cama-
ridium alliance). The flowers may be minute to
very large and showy and are variable in many
respects, although the column is always basally
produced into a more or less well-developed col-
umn-foot to which the labellum is hinged. Orni-
thidium Salisb. has a rigidly attached, unhinged
labellum, and thus we feel it should be recognized,
even though many authors do not do so. As a
member of the subtribe Maxillarinae, all Maxil-
laria species have four dorsiventrally flattened pol-
linia in two unequal pairs, more or less well-de-
veloped, usually semilunate viscidium, and variously
sized and shaped stipites or no stipe at a
In Venezuela there have been recorded about
75 species of Maxillaria, of which 47 are known
in the Venezuelan Guayana. All major groups with-
in the genus are represented in southern Venezuela.
In terms of numbers of species, Maxillaria is only
surpassed in the Venezuelan Guayana by Pleu-
rothallis R. Br. (ca. 57 species) and Epidendrum
L. (ca. 51 species). The next-largest genus is Oc-
tomeria R. Br. (ca. 29 species).

Leaves coriaceous, erect, narrowly elliptic, acute,
basally attenuate into a subcylindric pseudopetiole
4-4.5 cm long, leaf total length 23-24.5 cm, the
blade 18.5-20 cm long, 2.3-2.6 cm wide. Inflo-
rescences originating from the pseudobulb base,
flowers solitary; peduncle subterete, entirely con-
cealed by 4-5 tubulose, scarious sheaths, 3-5 cm
long. Flowers medium-sized for the genus, appar-
ently vertically erect. Perianth segments scarcely
open. Floral bracts elliptic, acute, 1.4-1.5 cm long,
0.4-0.5 cm wide. Pedicellate ovary apparently
subcylindric, 15-17 mm long. Dorsal sepal nar-
rowly oblong-elliptic, acute, 20-20.5 mm long, 4-
4.5 mm wide. Lateral sepals narrowly triangular,
acute, 20-21 mm long, basally 3.5-4
Petals narrowly elliptic, slightly obovate, acute or
narrowly obtuse, 19 mm long, 4-4.5 mm wide.
Labellum parallel to the column, in general outline
narrowly oblong, 17-18 mm long, 4.5 mm wide
at its broadest, slightly pandurate-trilobate above
the middle; central lobe elliptic, obtuse-rounded,
slightly concave, 7 mm long, 2.5 mm wide, basally
attenuate in a short unguiculus about 2 mm lon
and wide, the narrowly oblong longitudinal callus
mm wide
apically rounded and centrally concave, 7 mm long,
0.8 mm wide. Column straight or slightly recur-
vate, hemicylindric, ventrally concave, 8 mm long
and 2 mm wide at the thickened apical zone. Cli-
nandrium apiculate.
This species is very similar to M. auyantepuien-
sis, from which it differs in its inflorescences longer
than the pseudobulb (vs. subequal or shorter), nar-
rowly elliptic floral bracts (vs. widely elliptic), petals
to 4.5 mm wide (vs. at least 6 mm in M. auyan-
tepuiensis), and conspicuously narrower labellum
(in M. auyantepuiensis it is approximately twice
as long as wide vs. more than three times longer
than wide in M. foldatsiana). Further, the labellum
of M. foldatsiana is less trilobulate. As M. fol-
datsiana is only known from the type collection,
and the differences between the two species are
not deep, we feel that more material may show M.
foldatsiana to be only a variation of M. auyan-
tepuiensis. However, we have studied many spec-
imens of M. auyantepuiensis (alive and dried) and
have never noticed intergradation in the differential
characters, so we think that they are best treated
as closely related but distinct species.
This apparently scarce species has been col-
lected only once despite repeated collecting trips
to the summits of the tepuis in the last ten years.
Perhaps it is endemic to Uaipantepui.
We take great pleasure in naming this species
after our friend and colleague Dr. Ernesto Foldats,
orchidologist. He was the first to notice the new
species as undescribed.
Maxillaria auyantepuiensis is very common in
the Gran Sabana, in southeastern Bolivar, Vene-
zuela. Surprisingly, it is seldom collected. This
species comprises two infraspecific taxa, one of
which has remained undescribed.
Maxillaria auyantepuiensis subsp. auyante-
puiensis is terrestrial or lithophytic, always grow-
ing on sandy soils or on acid sandstone, forming
large colonies in more or less open places as scrub
or savannalike tepui formations. It is usually ex-
posed to full sun or resides under the light shade
of shrubs. Occasionally it reaches be p iin
margin or even its interior, provide
light and is always over sandstone DUREE or
sandy soil. Morphologically, M. auyantepuiensis
subsp. auyantepuiensis is highly variable with fu-
siform to (rarely) spherical pseudobulbs and sessile
to long-petiolate leaves. The sheaths that conceal
the pseudobulb do not defibrate but remain intact.
The inflorescences vary from shorter than to longer
than the pseudobulb and are always conspicuously
peduncled. The flowers are held in an upright or
suberect posture. The perianth segments are rel-
atively long and narrow with petals 18-19 mm
long, 4.3-4.5 mm wide (width/length = 0.38-
0.42) the dorsal sepal is 20-21 mm long and 3.5
mm wide (width /length = 0.16-0.17)

The subspecies are distinguished in Table 1.
Both subspecies have been illustrated in Dunster-
ville & Garay (1965: 181, 498). Plants A, C, and
D there depict the variation to be expected in M.
auyantepuiensis subsp. auyantepuiensis. Plant B
represents our new M. auyantepuiensis subsp. epi-
phytica.
The new subspecies comprises populations of
epiphytic plants from rain or cloud forest at vari-
able altitudes from 600 to 1,400 m, with spherical
or broadly ellipsoid pseudobulbs that are small in
proportion to leaf length and are concealed by
defibrating sheaths. These pseudobulbs occur on a
short to long, obviously creeping rhizome, which
adheres to the bark of the host tree. The leaves
are always long-petiolate and very elongate with
respect to pseudobulb length. The almost-epedun-
culate inflorescenses are always shorter than the
pseudobulbs, and the flowers are almost held hor-
izontally. The flowers are of proportionately smaller
dimensions than in subsp. auyantepuiensis, with
relatively broader perianth segments (dorsal sepal

0.27-0.31). The labellum is almost identical in the
two subspecies.
Maxillaria auyantepuiensis subsp. epiphytica
is superficially similar to the Ecuadorian species
. neophylla Reichb. f., but this has an acute
central labellum lobe. The new subspecies also sug-
gests a vegetatively reduced M. desvauxiana
Reichb. f. from the Amazonian Basin, but their
labella are very different, and M. desvauxiana does
not have defibrating sheaths concealing the pseu-
dobulbs.
The new subspecies has a wider distribution than
the typical subspecies and extends beyond the
Guayana boundaries. We know of a population in
Guatopo, Estado Miranda, of the Coastal Range,
represented by Patrszeck s.n., 13 Feb. 1963
(VEN), also a population from Barinitas, Estado
Barinas, in the Andean foothills, from which we
have living material but no voucher.
The typical subspecies appears to be restricted
to the acid sandy soils of the Roraima Formation,
and this may explain a limited range in geographic
terms even though it appears to be locally abundant
in its natural habit.

This relatively scarce species has a wide range
within the Venezuelan Guayana. One of the authors
collected living plants of it in 1982 in the sur-
roundings of Peray-tepui (W of Sta. Elena de Uai-
ren, Gran Sabana, Estado Bolivar), but no voucher
was made. The affinities of M. santanae lie with
all the species of the Dicrypta group: M. crassi-
folia Reichb. f.; M. superflua Reichb. f., and per-
haps M. bicallosa (Reichb. f.) Garay, M. char-
tacifolia Ames, and others. This is a difficult group
in need of revision—the characters distinguishing
the component members are not well defined and
seem unreliable. Among the Dicrypta group, M.
santanae can be easily recognized by its small
vegetative stature; very narrow leaves; broadly
ovate or broadly triangular, obtuse central labellum
lobe; and orange-yellow or rose-lilac labellum, which
has a callus in the disc and lacks another in the
central lobe as is usual in other species of the group.
We are pleased to name this species after Dr.
Gustavo Santana, an enthusiastic orchid collector
and knowledgeable amateur orchid grower. He col-
lected the living plant from which the holotype
specimen was prepared and kindly provided fresh
vegetative and floral material for study.

Distribution. Known from the rain forests be-
tween 80 and 200 m in the Amazonian Basin of
Peru, Brazil, and Venezuela.
This is the first record of this species for Ven-
ezuela. Since the Venezuelan material shows a few
differences with the other known populations, here
we offer a complete description with the full range
of variation. Maxillaria tenuis seems to be rather
variable. The type material from Iquitos, Amazo-
nian Peru (Klug 1045, US), has sepals about three
times longer than labellum (27:9.5 mm) and a
triangular-ovate central labellar lobe. The second
collection known, collected in Amazonian Brazil (G.
A. Black 48-2676, IAN; G. A. Black 48-2747,
IAN), has a very narrow central lobe (half the
width of the type material) and an apparently bi-
lobated labellar callus. Based on this Brazilian ma-
terial, a var. amazonica Pabst was described (Pabst,
1955). All persons experienced with Maxillaria
——— & F. =
herbarium material know how difficult it is to re-
hydrate and reconstruct labella in these species,
especially the central lobe and calluses, so we won-
er if the narrower central lobe and bilobated callus
are not artifacts. Provided they are not, we wou
think that var. amazonica could stand as a good
variety or subspecies, even though in Pabst &
Dungs (1975) they seem to have rejected Pabst’s
variety without explanation. The third population
of the species to be sampled is the one we report
here, which seems to depart from the type and
from Brazilian material in having shorter sepals,
less than two times longer than labellum (18: 10
mm). The labellum is identical with that of the type
material. By orchid standards this seems to be a
good difference for the recognition of at least a
subspecies, but we feel that the evidence is too
scanty, as is the known material, and further ma-
terial could bridge the gap between the three known
populations of this extremely variable species.
Maxillaria tenuis is a well-marked species, es-
pecially its vegetative morphology: oblongoid, elon-
gate pseudobulbs, linear leaves, and verrucose-pus-
tulose sheaths. San Carlos de Rio Negro is only a
undred meters away from Colombia, across the
Río Negro, so we would expect to find M. tenuis
also in Colombia.

Como parte de la revisión que se esta realizando
del genero Mimosa L. para la Argentina, Bolivia,
Paraguay, y Uruguay, se da a conocer el estudio
taxonómico de cuatro especies presentes en el área.
Estas especies pertenecen a la sección Mimosa
(Bentham, 1842, 1875) por presentar flores ha-
plostémonas.
Dentro de dicha sección, segün ciertos carac-
teres exomorfológicos (hábito, presencia de acú-
leos, nümero de pinnas, nümero de foliolos) se
agruparia a M. pauperioides y M. balansae en
la serie Pectinatae Benth. y a M. niederleinii y
M. petraea en la serie Pedunculosae Benth.
En el sistema de clasificacion de Bentham, la
ubicación taxonómica de muchas de las especies
de Mimosa en cada serie es dudosa. A través del
estudio biosistemático que se esta efectuando en el
género para Austroamerica se espera poder se-
leccionar los caracteres de valor taxonómico.

balansae por presentar foliolos más angostos y el
nervio medio prominente. En el material estudiado
se observó que ademas de los caracteres citados
por Burkart, también se podia diferenciar a M.
balansae var. balansae por poseer inflorescencias
mayores que las hojas, y tallos inermes o con l-
2 acüleos internodales y/o infraestipulares. Todas
estas diferencias se mantienen constantes, e inclu-
sive son más importantes que las existentes entre
M. balansae y otras especies afines. Por lo aqui
descrito, se propone considerar a M. pauperioides
como especie independiente de M. balansae.
En los ejemplares inermes es facil confundir a
M. pauperioides con M. petraea. Ambas presen-
tan afinidad en el tipo de hábito y nümero y forma
de los foliolos; no obstante se diferencian por el
largo del pedünculo, pubescencia, y tamano de los
foliolos.
Segün Bentham (1842, 1875), la serie Pecti-
natae Benth. se caracteriza por agrupar sufrütices
pequenos o raro arbustos, generalmente con acü-
leos infraestipulares o internodales, pinna uniyu-
gada, foliolos multiyugados (a veces hasta 6-8-
yugados) pedúnculos 1(2) axilares o formando
racimos compuestos apicales (desarrollo posterior
de las hojas), racimos globosos, flores 4-meras, y
craspedio setoso a hispido. A su vez, la serie Pe-
dunculosae Benth. se diferencia de Pectinatae casi
ünicamente por incluir especies inermes. En e
estudio de ambos grupos supraespecificos, se ha
observado que la presencia de acüleos es un ca-
racter variable en muchas especies del género,
como ocurre con M. pauperioides. Este taxon solo
presenta algunas ramas con uno o dos acüleos
pequenos, y a veces es una planta totalmente iner-
me. Si se siguiera el criterio de Bentham, erró-
Pedunculosae. Por otro lado, esta especie es más
afin a M. petraea de la serie Pedunculosae. Como
se ha senalado, en su mayoria, los caracteres di-
ferenciales descriptos por Bentham para las series
del género Mimosa no responden a un patrón
estable.

Se ha observado en el campo y en el material
de herbario que M. balansae forma un complejo
donde los caracteres descriptos (hábito, pubescen-
cia, número de acúleos, largo de la pinna, y número
y largo de foliolos) aparecen combinados en los
diferentes ejemplares. Esta variabilidad imposibilita
realizar una división infraespecifica natural de la
especie, por ello se considera que los epítetos va-
rietales robusta y rojasiana son solo probables
formas ecológicas que presenta el complejo citado.
Mimosa balansae var. rojasiana fue descripta
por Hassler con foliolos glabrescentes en la cara
adaxial. Al estudiar el material típico se pudo ob-
servar que los foliolos son pubescentes en ambas
caras.

En 1947, Burkart describió para Rio Grande
do Sul a M. niederleinii var. riograndensis; pos-
teriormente, en 1979 la citó para el Estado de
Santa Catarina. Segün él, esta variedad se dife-
renciaba por presentar foliolos pubérulos en la cara
abaxial y pinnas 24—54-yugadas, mientras que la
var. niederleinii se caracterizaba por poseer folio-
los con la cara abaxial pubérula y estrigosa y pinnas

19-32-yugadas. El material tipo consultado de M.
niederleinii var. riograndensis posee la mayoria
de los foliolos con pubescencia pubérula, pero, tam-
bién, se pueden observar algunos pelos estrigosos
mezclados, como ocurre en la variedad tipica. Con
respecto al nümero de foliolos por pinna, es con-
veniente senalar, que el material tipo de M. nie-
derleinii es un ejemplar pobre y las pinnas no
poseen completos los pares do foliolos. Por otro
lado, en el material brasileno, se han observado
varios ejemplares con pinnas 30-50-yugadas pero
con pubescencia pubérula y estrigosa en la cara
abaxial de los foliolos. Ante la variabilidad obser-
vada en los ünicos caracteres diferenciales, se pro-
pone en esta nota considerar en la sinonimia de
M. niederleinii a la var. riograndensis.
ta de M. niederleinii para la Argentina fue
realizada sobre la base del ejemplar tipo coleccio-
nado en Varana (?), Misiones, por Niederlein en
la expedición de la Comision Nacional de Limites.
En 1948, Burkart senala que dicha localidad per-
tenece a la parte centro-oriental de la provincia de
Misiones, en la region de Fracrán. A pesar de la
especificación posterior, desde 1887 hasta el mo-
mento, no se ha encontrado nuevamente material
de esta especie en la Argentina, en cambio si es
común hallar ejemplares recientemente coleccio-
nados en el SE brasileno; existe la posibilidad que
el material citado fuera coleccionado en el estado
de Rio Grande do Sul y no en el territorio argentino.
Esta especie posee una variedad en el Edo. de
Santa Catarina, Brasil: M. niederleinii var. pseu-
dolepidota Burk. Esta variedad presenta tallos,
peciolos, pedünculos, y craspedio con pubescencia
densa, estrigosa o setulosa, y ramificada.

En 1948 y 1952, Burkart citó a esta especie
para la Argentina sobre la base del ejemplar: ““Mi-
siones, Bonpland, P. Jorgensen 325, IX-1909 (BAB
34712)". En el material estudiado solo se pudo
encontrar un ejemplar de herbario que si bien posee
los mismos datos citados en la exsiccata por Bur-
kart, no coincide en la fecha de colección. En la
etiqueta del material se lee XI- 1909 y no IX-1909.
Esta diferencia probablemente se deba a un error
de impresión. Por otro lado, el ejemplar Jorgensen
325 (BAB 34712) no pertenece a M. petraea, sino
a una forma más pequeña y pubescente de
oligophylla M. Mich. Al revisar todo el material
depositado en el herbario del Depto. de Botánica
Agricola, INTA, Castelar (BAB), se pudo compro-
bar que existen más ejemplares de P. Jorgensen
325, los cuales corresponden a distintos nümeros
de BAB y a diferentes especies de Mimosa, por
ej.. BAB 30213, 30214, 30224 = M. oligophyl-
la; BAB 32116, 32117, 32118 = M. paupera

En el material examinado de M. petraea (Bur-
kart, 1948), fue citado otro ejemplar: “Paraguay,

a la variedad tipica, sino a M. petraea var. hirtula
Burk. Dicho ejemplar, al igual que el tipo y demás
especimenes estudiados de var. hirtula se diferen-
cian de var. petraea por ser un sufrütice erecto a

GROUP 3. THE GRACILIFLORA GROUP
Shrub or sometimes small tree; young stems
glabrous or sometimes ferrugineous-pubescent;
stipules sheathing or not, triangular or ovate or
lanceolate, the apex often bifid or biaristate (Fig.
2f), uniform in color, glabrous or less commonly
fringed or ferrugineous-puberulent, caducous. Leaf
blades usually elliptic, sometimes narrowly so, or
oblanceolate or slightly obovate, drying reddish
or greenish gray, brown, or black; secondary
veins 3-14(-16) pairs, diverging (45?-)55?-
90(-100%), eucamptodromous or brochidodro-
mous, with collector vein only in P. jimenezii, the
axils with domatia (Fig. 4b) or not (with tufts of
hair only occasionally in P. bakeri); tertiary veins
orthogonal reticulate (sometimes percurrent in P.
marginata). Inflorescences panicles of cymes or
rarely (P. bakeri and sometimes P. parvifolia) of
glomerules, usually pedunculate; secondary axes
usually in 1 pair per rank, if more than 1 pair
then size-differentiated, often delicate or diffuse in
structure and diverging at right angles (Fig. 7h);
bracts rarely conspicuously enlarged (to 6 mm long
in P. jimenezii). Corolla tubes (1.5-)2-4(-5) mm
long (Fig. 8), the lobes usually without apical ex-
tensions (sometimes with blunt protuberances in P.
graciliflora). Fruit when dry usually ellipsoid to
spherical (obloid in P. philacra); persistent calyx
a beak or not evident; seed dorsal surface with
3-5 (6-8 in P. parvifolia) usually deep longi-
tudinal furrows (Fig. 10d), the ventral surface with
2 deep or broad longitudinal furrows (plus several
irregular furrows in both surfaces in P. philacra;
ventral surface often concave in P. graciliflora
[ Fig. 10c
The most commonly encountered species in the
group, Psychotria marginata (distribution, Fig.
20), does not obviously closely resemble any other
species. Psychotria graciliflora (Fig. 21), the oth-
er widespread species, is the centerpiece of the
morphologically cohesive P. graciliflora complex,
which includes also P. bakeri (Los Santos, Pana-
ma), P. laselvensis (Costa Rica), P. liesneri (east-
ern Panamá Province), P. orosiana (Costa Rica
and Panama), P. parvifolia (Costa Rica and west-
ern Panama), and P. philacra (eastern Darién
Province; see Fig. 22). Psychotria jimenezii, a
Costa Rican species (Fig. 23), is unique in the group
in having a collector vein, inflorescence bracts as
long as 4-6 mm, and seed dorsal surface with
usually only three longitudinal furrows, but it too
may belong to the P. graciliflora complex.
Of the nine species in the group, six appear
distylous. All six show between-morph asymmetry
in floral part lengths: Psychotria graciliflora, P.
jimenezii, P. laselvensis, P. marginata, and P.
parvifolia have longer-exserted parts in pins than
in thrums, and in P. orosiana pin reproductive
organs are longer at both levels. The only positively
derived state is seen in P. liesneri, which is long-
homostylous. Available flowering material of P.
bakeri and P. philacra is insufficient to determine
their breeding systems.

in South America and apparently absent from the
Antilles. Psychotria graciliflora has the greatest
elevation range of any species of the subgenus,
ranging 0—2,500 m, and occurs in tropical moist
to lower montane rainforest with equatorial and
tropical climate. It has been collected in flower
January- August, primarily March-July, and in fruit
throughout the year, primarily August- February.

Types of P. oaxacana and P. vallensis have
morphologies well within the normal range of P.
graciliflora and are therefore included.
Psychotria graciliflora may be recognized by
its fairly small (usually 3-8 x 1.3-3 cm) glabrous

i ce and its small (4-5 x 3-4 mm) el-
lipsoid to spherical fruits often drying black. Leaves
in Honduras and Nicaragua are at the upper end
of the spectrum in terms of size and number of
secondary veins, whereas Costa Rican specimens
generally have the smallest leaves with the fewest
secondaries. Calyx lobes are generally barely evi-
dent to triangular, but in Darién and eastern Pana-
má provinces the lobes are linear.
The exserted style in the pin morph is noticeably
longer than the exserted stamens in the thrum (4—
5 vs. 2.5-3 mm).

its resemblance to P. graciliflora and P. orosiana
and its generally larger inflorescences and leaves.
It differs from P. orosiana in having leaf blades

veins (usually 10-13 vs. 7-9), inflorescence sec-
ondary axes commonly 4 (vs. 2) in the first rank,
and usually shorter corolla tubes (2.5-3 vs. 2.5-
5 mm). These three closely related species— P.
graciliflora, P. orosiana, and P. laselvensis—
form a continuum with regard to many quantitative
characters, but their recognition as species is
straightforward.
The exserted pistil in the pin morph is conspic-

Psychotria liesneri may be recognized by its
small elliptic (usually 4.5-6 x 1.5-2.2 cm) often
subcoriaceous leaves with inrolled margins,
brochidodromous secondary venation, and small
(1.5-3 cm long) inflorescences with secondary veins
usually in 2 ranks.
In both flowering collections, the negligible sep-
aration between style and stamens suggests that
the species is long-homostylous instead of distylous.

Psychotria marginata may be recognized by
its oblanceolate long-acuminate leaves drying usu-
ally red-gray, eucamptodromous secondary vena-
tion with axillary domatia, large (usually 10-15
cm long) diffuse panicles of cymes with delicate
axes diverging at right angles, and small (3.5-4
mm) spherical fruit drying black. Psychotria mar-
ginata is remarkably uniform in qualitative and
quantitative aspects throughout its broad range.
The exserted pistils in the pin morph are longer
than the exserted stamens in the thrum (4-4.5 vs.
3.5 mm).

Psychotria orosiana may be recognized by its
resemblance to P. graciliflora—leaves drying
blackish, secondary veins diverging ca. 80°, inflo-
rescence axes delicate—and by its larger (3.5-10
vs. 3-5 cm long) inflorescences, longer corolla tube
(2.5-5 vs. 2-2.5 mm), and seed dorsal surfaces
with deeper longitudinal furrows having acute lon-
gitudinal ridges between.
e reproductive parts at both levels are longer
in pin morphs than in thrums.

type collection from Cerro Tacarcuna, eastern Da-
rien, Panama, at 1,250- 1,450 m elevation in low
montane rainforest with equatorial-mountainous
climate. It was collected in fruit on January 26.
Psychotria philacra may be recognized by its
small elliptic (5-7 x 1.7-2.7 cm) leaves drying
dull red-brown and with 6-7 secondary veins, ob-
loid fruits, and seeds with shallow irregular furrows
on both surfaces.
GROUP 4. THE REMOT4 GROUP
The description for the group in Mesoamerica
is that of the lone species, Psychotria remota. Key
recognition characters include leaves drying glossy
red-brown and relatively few secondary veins for
the large size of the blade. This group is larger in
South America, including also P. anceps Kunth
and P. cupularis (Muell. Arg.) Standl.
Psychotria remota appears normally distylous,
with no floral-part-length asymmetry between the
morphs.

The inclusion of P. alboviridula within P. re-
mota is discussed by Steyermark (1972; Mem.
New York Bot. Gard. 23: 477)
Psychotria remota may be recognized by its
moderately large (usually 11-24 cm long) elliptic
leaves drying glossy red-brown, few (usually 8-12)
secondary veins generally with prominent domatia
in the axils, reduced (except for the first rank) and
winged secondary inflorescence axes, and large
(usually 7-9 mm long) ellipsoidal fruit.
GROUP 5. THE NERVOSA GROUP
Shrub; young stems glabrous or red-brown to
brown tomentose to puberulent; stipules usually
sheathing, linear (Fig. 2c) or ovate, the apex some-
times bilobed or paene uniform in color (except
P. fosteri, with a darker red-brown midrib), gla-
brous or fringed or red- brown pubescent, caducous.
Leaf blades obovate or elliptic or oblanceolate,
drying red-brown to green-brown (often chalky yel-
low-green in P. fruticetorum), sometimes pale be-
low; secondary veins (4-)5-17 pairs, diverging
35°-65° (except 70?-80? in P. fosteri), eucamp-
todromous or brochidodromous (with collector vein
in P. chagrensis and P. fosteri), the axils usually
with tufts of hairs (lacking in P. chagrensis, P.
fosteri, and usually P. nervosa); tertiary veins re-
ticulate or percurrent. Inflorescences panicles of
cymes (often contracted in P. nervosa) or fascicles
of flowers (in P. chagrensis and P. fosteri), not
pedunculate (except P. erythrocarpa, P. fruti-
cetorum, and often P. jinotegensis); secondary
axes usually in 1 pair or less commonly 2 size-
differentiated pairs per rank (4 equal axes per rank
rarely in P. nervosa); bracts conspicuously en-
larged in P. chagrensis, P. fosteri, and P. fruti-
cetorum. Corolla tubes 2-4 mm long (6-7 mm in
P. chagrensis), the lobes without apical extensions.
Fruit ellipsoid when dry (narrow in P. nervosa);
persistent calyx a tube to 5 mm long (Fig. 9d)

or a beak or inconspicuous; seed dorsal surface
with 4-5 deep longitudinal furrows (or 6-8-
many irregular furrows in P. aguilarii and P.
Jinotegensis), the ventral surface with 2 deep or
shallow longitudinal furrows, sometimes incom
pletely divided in P. nervosa or with additional
irregular furrows in P. jinotegensis.
Of the nine species, three fairly widespread ones
do not closely resemble any others: Psychotria
fruticetorum, with its biaristate stipules, leaves
drying chalky yellow-green, pedunculate inflores-
cences, and bracts as long as 8 mm; P. erythro-
carpa, with its linear stipules and pedunculate
inflorescences often of glomerules; and P. jinote-
gensis, with its often pedunculate inflorescences
and many irregular furrows on both seed surfaces.
The P. chagrensis complex shares a collector vein,
an absence of tufts of hairs in the axils of the
secondary veins, and inflorescences of fascicles of
flowers and with bracts conspicuously enlarged; the
complex comprises the widespread P. chagrensis
and P. fosteri, endemic to Coiba Island, Panama
(Fig. 26). The P. nervosa complex includes that
widespread species plus P. aguilarii (southern
Guatemala), P. boquetensis (western Panama), and
P. mirandae (southern Mexico); none of them de-
viates morphologically from the predominant char-
acter states of the group
Of the nine species in the group, seven appear
distylous. Of those, Psychotria fruticetorum has
onger exserted parts in the pins than in thrums,
and P. chagrensis has longer inserted parts in the
pins. One species, P. mirandae, appears to be
thrum-monomorphic. Only P. fosteri may not be
evaluated for this character due to lack of adequate
flowering material.

Psychotria aguilarii may be recognized first by
its striking resemblance to P. nervosa. The former
differs in being generally glabrous (as is P. nervosa
sometimes) and in having leaves with crenulate leaf
margins, inflorescence secondary axes in 2 (vs. 3-
4) ranks, longer corolla tubes (3-3.5 vs. 2-3 mm),
fruit less narrowly ellipsoidal (length/width — 1.5
vs. ca. 2.2), and seed dorsal surface with many
irregular shallow furrows (vs. 4—5 regular furrows).

Psychotria boquetensis may be recognized first
by its striking resemblance to P. nervosa. Psy-
chotria boquetensis differs in having often linear
mm (vs. to 0.2 mm)
long; in quantitative characters such as leaf and
inflorescence size, P. boquetensis falls at the lower
end of the P. nervosa spectrum.

Psychotria chagrensis may be recognized
readily by its inflorescences consisting of fascicles
of several flowers, its large (5-7 x 5 mm
fruit with conspicuously persistent calyx usually 3-
4 mm long, and small leaves (usually 4-7.5 X
1.5-2.5 cm). Leaves appear at the lower end of
the given size range in Costa Rica and at the higher
extreme in Mexico and Guatemala.
The inserted stamens of the pin morph are longer
than the inserted pistil of the thrum (5.5-6.5 vs.
2-5 mm)

A minority of glabrous individuals appear in
many populations of Psychotria erythrocarpa (D.
Lorence, pers. comm.), so P. chamissoana, defined
by its glabrous aspect, is included within P. ery-
throcarpa.
Psychotria erythrocarpa may be recognized by
its usually pale brown to red-brown tomentose as-
pect, obovate leaves with few (usually 6-8) sec-
ondary veins diverging acutely (35?—50*), and small
(usually 2.5-5.5 cm long) inflorescences with sec-
ondary axes two per rank in three ranks. The fruits
occupy the small end of the spectrum in Veracruz
and the large end in Chiapas and southward.

Psychotria fosteri may be recognized as a mag-
nified version of P. chagrensis, having an inflo-
rescence consisting of a fascicle of flowers and fruit
ellipsoid with a conspicuous persistent calyx. Psy-
chotria fosteri differs in having larger (sheath 8-
vs. 4-7 mm long) biaristate (vs. aristate) stip-
ules, larger mature leaves (usually 8-12 x 3-5
vs. 4-7.5 x 1.5-2.5 cm), shorter calyx lobes
(0.5-1 vs. 2-2.5 mm), and much shorter corolla
tubes (3.5 vs. 6-7 mm).
The lone flowering collection is a pin morph.

Psychotria fruticetorum may be recognized by
its small leaves (usually 5-7 x 2-4 cm) drying
chalky yellow-green to red-brown with barely el-
evated secondary veins and inconspicuous tertia-
ries, its small inflorescences (1.5-4.5 cm long) with
secondary axes usually 2 per rank in 3-4 ranks,
and small (4-5 x 3-3.5 mm) ellipsoid fruit. Mex-
ican collections differ from those from the rest of
the range in having generally smaller leaves, 5 vs.
6-7(8) secondary veins, and a higher fruit length-
to-diameter ratio.
The exserted pistil of the pin morph is often
longer than the exserted stamens of the thrum
(3.5-5 vs. 3.5-4 m

Psychotria mirandae may be recognized first
by its marked resemblance to P. nervosa and sec-
ond by its contracted (sometimes contracted to
fascicles of flowers) inflorescences and wider (4-5
mm vs. 2.5-3 mm diam. in P. nervosa) fruit with
persistent calyx having a conspicuous tube and
lobes ca. 4 mm long.
The seven flowering collections examined are all
of the thrum morph, which suggests strongly that
the species is thrum-monomorphic.

southern Mexico and the Yucatán peninsula through
Panama, most common on the Caribbean coast, at
0- 1,200 m elevation in tropical moist to premon-
tane moist to sometimes tropical dry forest with
equatorial to tropical (usually equatorial-tropical)
climate. It occurs also in Florida, the Bahamas,
throughout the Greater and Lesser Antilles, Colom-
bia, and Venezuela. It has been collected in flower
throughout the year, primarily February-June in
Mexico-Costa Rica and throughout the year in
Panama, and in fruit throughout the year.

All the species in synonymy have been properly
synonymized before, with the exception of P.
quiinifolia, the morphology of which does not differ
from that of P. nervosa. Degree of pubescence
varies within populations, and infraspecific taxon-
omy based on this character (e.g., subsp. rufescens)
is not recognized.
Psychotria nervosa may be recognized by its
usually reddish pubescent aspect, leaves with usu-
ally eucamptodromous secondary veins diverging
55?-65^, small (1-4(-5) cm long) inflorescences
lacking peduncles and with secondary axes usually
2 per rank in usually 3 ranks, and narrow-ellip-
soidal fruit (5.5-7 x 2.5-3 mm). There appears
to be no geographic component to the variation
between glabrous and densely tomentose aspect.
Collections from Florida are noteworthy for small
eaves and relatively large inflorescences.
GROUP 6. THE PANAMENSIS GROUP
Shrub or tree; young stems glabrous or (often
red-brown) puberulent; stipules usually sheathing,
lanceolate (Fig. 2d) or ovate, or less commonly
linear or triangular with the apex sometimes bilobed
or biacuminate, uniform in color, glabrous or fringed
or puberulent, caducous. Leaf blades usually ellip-
tic, or sometimes obovate, ovate, or lanceolate,
drying green-brown to red-brown to brown, some
times paler below; secondary veins (4—)6- 19(- 22)
pairs, diverging (30?-)45?—75*(-809), eucampto-
dromous to brochidodromous, the axils sometimes
with domatia (sometimes P. cocosensis and P. lun-
dellii) or with tufts of hair (sometimes P. chiri-
quina, P. lundellii, and P. mexiae) or usually
lacking; tertiary veins orthogonal reticulate to per-
current. /nflorescences panicles of cymes (or of
glomerules sometimes in P. panamensis or of in-
dividual flowers in P. hornitensis), nonpeduncu-
late (Fig. 7e) except in P. olgae, P. stockwellii,
and sometimes in P. cascajalensis, P. chiriquina,
P. dwyeri, P. lundellii, P. panamensis, P. sara-
piquensis, and P. trichotoma; secondary axes
usually in 1 pair per rank or less commonly 2
equal pairs or 2 size-differentiated pairs per rank,
diverging acutely except in P. stockwellii; bracts
not conspicuously enlarged, to 3 mm long only in
P. chiriquina. Corolla tubes (1.5-)2-5 mm long,
the lobes without apical extensions. Fruit ellipsoid,
obovoid, or spherical when dry; persistent calyx
a beak or less commonly a conspicuous tube (P.
cocosensis [Fig. 9c] and P. olgae and sometimes
P. panamensis) or often not evident; seed dorsal
surface with (3—) 4—10 often irregular longitu-
dinal furrows, the ventral surface with 2 deep plus
often several irregular longitudinal furrows (Figs.
10g, 10h)
Half of the 12 species of the group are assigned
to the Psychotria panamensis complex; P. pana-

mensis is widespread (Fig. 28), the other five much
less so: P. cascajalensis (Coclé, Panama; Fig. 29),
P. cocosensis (Cocos Island, Costa Rica; Fig. 28),
P. dwyeri (southern Mexico; Fig. 29), P. olgae
(eastern Panamá Province; Fig. 29), and P. stock-
wellii (Costa Rica and Panama; Fig. 30). Three
other widespread species have character states that
distinguish them from typical members of the group
and are of uncertain affinities, although analysis
might reveal they belong in the panamensis com-
plex: P. trichotoma has obovoid fruits and con-
spicuously brochidodromous venation; P. sarapi-
quensis has usually narrowly oblanceolate leaves;
and P. mexiae has 5-8 deep irregular furrows on
the seed dorsal surface. The most cohesive complex
is that of P. chiriquina, which includes that species
(Nicaragua through Panama; Fig. 29), P. lundellii
(Chiapas through El Salvador; Fig. 29), and P.
hornitensis (western Panama; Fig. 30); they share
ovate stipules and shallow furrows on the see
ventral surface.
Of the 15 taxa in the group, eight appear di-
stylous; of those, Psychotria dwyeri, P. mexiae,
olgae, P. stockwellii, and P. trichotoma show
some between-morph asymmetry in floral part
lengths. Psychotria lundellii appears to be pin-
monomorphic in Belize, but recently I examined a
thrum collection from Guatemala. Psychotria
compressicaulis (solid

hand, is thrum-monomor

Psychotria chiriquina may be recognized by its
small (usually 6.5-9 x 1.5-2.5 cm) narrow-elliptic
leaves drying deep red-brown, deeply longitudinally
fissured bark, long (4-6 mm) corolla tube, and
robust (5-6 x 4-4.5 mm) ellipsoid fruits drying
deep red-brown. There are several differences not-
ed in collections from Nicaragua as opposed to
those from Panama. Nicaraguan material shows
fewer (5-7 vs. usually 8-1 1[-12]) secondary veins
and more acute (30°-50° versus 55?-65?) angles
of divergence of secondaries. Panamanian material
shows often pedicellate inflorescences and fruits
with a more prominent persistent calyx.

Psychotria lundellii may be recognized by its
narrow (length/width — 3) leaves drying glossy
red-brown with few (usually 6-8) secondary veins
and tertiary veins not evident, and its spherical
fruit drying often glossy red-brown and appearing
smooth outside due to the seed dorsal surface hav-
ing 3-6 shallow irregular longitudinal furrows. Psy-
chotria lundellii differs from the similar P. chi-
riquina in having smaller (5-6 vs. 8-10 mm long)
stipules, brochidodromous (vs. eucamptodromous)
secondary venation, shorter (2-2.5 vs. 4-6 mm
corolla tubes, and spherical (vs. ellipsoid) fruits.
Material from El Salvador shows generally more
secondary veins in the leaves than material gath-
ered elsewhere.
Eight flowering specimens from Belize have been
examined, and only the long-style morph has been
found, suggesting that the short-style morph has
been lost in populations in that country. One thrum
has been found in Baja Verapaz, Guatemala (Lun-
dell & Contreras 21037)

Palicourea nigrescens and Psychotria schippii
are morphologically identical to P. mexiae and are
therefore included. The existing name Psychotria
nigrescens De Wild. (dating to 1924) leaves ““mex-
iae" as the oldest available epithet.
Psychotria mexiae may be recognized by its
elliptic long-acuminate leaves drying green-brown
to red-brown with veins drying reddish below; glo-
bose panicles without peduncle and with 4 equal
secondary axes in each of the first 2 ranks; long
(2.5-4.5 mm) corolla tube often drying pink; and
ellipsoid to spherical fruit drying often shiny red-
brown and appearing smooth outside due to the
irregularity of the furrows on the dorsal surface of
the seed. Corolla tubes are shorter in specimens
from Belize (2.5 mm) than in those from Mexico
(4-4.5 mm), and the stamens and styles are scaled
down accordingly. Fruits are larger (5-6 mm long)
in specimens from Veracruz and Guatemala than
from elsewhere (4.5-5 mm long).
The exserted pistil of the pin morph is usually
longer than the exserted stamens of the thrum (4—
7 vs. 3.5-5.5 mm).

This variety, with its leaves drying greenish and
fruit obovoid, may be the result of local introgres-
sion involving Psychotria trichotoma in the Ixtlán
region of Oaxaca.
Four flowering collections are all of the pin
morph, suggesting (albeit weakly; p = 0.125) that
the variety may be pin-monomorphic.

The morphologies of P. grandistipula Standl.,
P. yunckeri, P. molinae, and P. durilancifolia
fall well within the broad range of P. panamensis
var. panamensis, so these former species are
esed with var. panamensis.
Psychotria panamensis var. panamensis shows
great variation within its range, including the fol-
lowing: leaves from Veraguas, Panama, are nar-
rower and more coriaceous than those from else-
where; leaves from Colón, Panama, are unusually
large; secondary veins are more numerous in ma-
terial from Guatemala, Honduras, and Colón and
fewer in material from Chiapas, Mexico, and from
Coclé, Panamá, and Veraguas provinces in Pan-
ama; secondary vein angle of divergence is greatest
in leaves from Chiriqui, Panama; secondary veins
are brochidodromous in Nicaraguan specimens; in-
florescences are largest in specimens from Panama
and Costa Rica; flowers are generally larger in
Costa Rican material; and the corolla tubes from
Honduras are narrowest (1.5 mm)

Psychotria sarapiquensis may be recognized
by its usually narrow (length/width — 3) leaves
with few (6-9[-11 ]) secondary veins and its large
(7-8 mm long) ellipsoid to often obovoid fruit drying
black or dark red-brown.
Mexican material is noteworthy for having lan-
ceolate leaves with secondary veins diverging 60?-
70°. Collections from the Fortuna and El Valle
areas in Panama have large (to 18 cm long) broadly
elliptic leaves with ca. 11 secondary veins, but
they fit this species concept in other respects. Three
of the Costa Rican collections— Dryer 1539 (not
cited above), Skutch 3282, and Haber 53 1 —have
subcoriaceous leaves drying red-brown and pedun-
culate inflorescences. Psychotria sarapiquensis is
the most variable and/or the most problematic
species in this treatment; it is conceivable that
additional material from throughout its range will
reveal it to be two or perhaps three different taxa.

Psychotria stockwellii may be recognized readily
by its inflorescence, whose secondary axes diverge
over 90? from the main axis and whose tertiary
axes diverge likewise from the secondary axes, and
so forth, a character state unique in the subgenus.
In addition, P. stockwellii differs from P. pana-
mensis in having a larger corolla tube (4-5 vs. 2-
3 mm long), long-pedunculate inflorescences, and
conspicuous to evident (vs. inconspicuous) tertiary
veins.
Reproductive organs at both levels are longer
in the pin morph than in the thrum.

Recent collections and older ones recently iden-
tified correctly to genus have yielded five new species
of the tribe Memecyleae DC. (Melastomataceae).
Four of these are members of the genus Mouriri:
one from the Osa Peninsula of Costa Rica, one
from western Venezuela in the state of Táchira, a
third from southern Venezuela in Amazonas, and
the fourth from northeastern Peru and adjacent
Brazil. Also in Mouriri, new collections of M. glea-
soniana from the Panama mainland, from Costa
Rica, and from the island of Coiba revealed much
intraspecific variation and require reassessment of
the status of its close ally, M. coibensis. A recent
flowering collection of M. longifolia permits the
completion of its description and illustrations and
allows its sectional placement. The fifth new species
is a Votomita from Roraima of Brazil, the eighth
known member of that small genus. The specimens
of this species, as well as those of another collection
of V. pubescens, bear ripe fruit, so that it is now
possible to compare more accurately the seeds of
Votomita and Mouriri. Previously, mature seeds
were known only from V. monantha of Cuba. A
discussion of ovule and seed structure and of ge-
neric relations therefore follows the description of
V. roraimensis. More collections of V. pubescens
make possible the completion of the descriptions
and illustrations for that species.
References in the descriptions to the "type" of
stomatal crypt refer to the forms described on
pages 6 and 7 of Morley (1976).

of stomatal crypts, simple upper epidermis with
mucilaginous walls, stellate terminal sclereids, and
lack of a hypodermis. Within the section, the new
species is closest to M. completens, on the basis
of the former's similar leaves with a cordate ten-
dency, very similar upper epidermis and foliar
sclereids, and above all, the circumscissile hypan-
thium as seen on the fruit. The absence of flower
characters of course detracts from understanding
the relationships, but I still regard this alignment
as reasonably certain. Mouriri osaensis differs from
M. completens in leaf, fruit, and seed characters.
The leaf blade is less cordate than in M. comple-
tens; the fruit is purple instead of greenish, lacks
a broad stipe at base, and is not abruptly narrowed
to the hypanthium at the apex, nor is it lobed
according to the seed number; the hypanthium on
the fruit is 7-11 mm in diameter rather than 4.5-
7 as in M. completens and is only 1.5-2 mm deep
instead of 3.8-4.5 mm. The seeds are a bit smaller
and differ in shape, best compared in the illustra-
tions.

This species is best placed in the sect. Mouriri
(Morley, 1976: 36) on the basis of its tubular
midrib xylem, small Type II stomatal crypts, hy-
podermis, acuminate leaf apex, axile-basal placen-
tation, and relatively short thecae. Section Lito-
phyllum is very similar, differing only in its lack

appears to be derived from the inner layer of a
double or triple epidermis, judging by the presence
in its cells of mucilage walls and the occasional
alignment of the hypodermal cells with cells or
groups of cells in the epidermis. In M. papillosa
the alignment is rather frequent, as seen in section
view; however, as seen in face view, the cells are
most often unaligned. Thus the inner layer of cells
appears to be sufficiently modified to justify con-

between calyx lobes. It further differs from M.
barinensis in having short petioles.
The curious multiple lamellations in the mucilage
walls of M. papillosa I have noted elsewhere only
in two collections of M. barinensis. Since this char-
acter varies in the latter species, it is possible that
it will also prove to be a variable in M. papillosa.
Although plants of sect. Litophyllum lack a
hypodermis, in other respects some of them re-
semble rather closely the members of sect. Mouriri.
Most similar is M. gleasoniana, including its var.
coibensis. From this, M. papillosa differs in its
lack of a two-winged lower midrib and in its pa-
pillose ovary and longer ovary plus calyx, longer
anthers and thecae, and greater splitting distance
between the calyx lobes.

Distribution. Known only from the type lo-
cality in tropical rainforest near the west-central
border of Amazonas, Venezuela, between the head-
waters of the Guainía and Atabapo rivers.
Mouriri latihila clearly falls within subg. Mou-
riri on the basis of its tubular midrib xylem and
its seed with a large polished area. The new species
is very distinctive, standing apart on the combi-
nation of its tetramery, closed calyx, and small
Type II stomatal crypts. Its sectional relation is
uncertain; it is here placed tentatively in sect.
Litophyllum because of its tubular midrib xylem,
small crypts, leaf shape, small flower, and lack of
a hypodermis (Morley, 1976: 36). When placed
here, it weakens further the already weak sectional
boundaries. From this position the new species ap-
pears to have ties with sect. Megacrypta, whose
two species also have tetramery, closed calyces,
and columnar sclereids. The new plant differs widely
from these two, however, in its much smaller leaves
and small Type II stomatal crypts, as well as in its
shorter pedicels and calyces. Within sect. Lito-
phyllum, no species appear very similar to M.
latihila, although two are tetramerous and have
short one-flowered peduncles like the new species:
M. exadenia and M. lancifolia. Mouriri latihila
differs from M. exadenia in having Type II crypts,
columnar sclereids, a closed calyx, and a different
seed shape; from M. lancifolia it differs in its
broader leaves, presence of stomatal crypts, co-
lumnar sclereids, and closed calyx.

This species, like the foregoing one, falls in subg.
Mouriri, its tubular midrib xylem, anatropous
ovules, and polished seed being the determining
features. The tetramery, monoporous and eglan-
dular anthers, and persistent petals of this entity
make it very distinctive. This is only the second
species of the genus to be found with monoporous
anthers, and persistent petals have not been noted
before. The petals were persistent on the green but
nearly ripe fruits of the type collection; they were
gone from the ripe fruit of the paratype. It is
impossible to know if they had dropped naturally
or were broken off during collection in the latter
case. Within its subgenus the new species is most
similar to three species in sect. Litophyllum: M.
exadenia, M. latihila, and M. monopora. Prob-
ably M. retentipetala is most closely related to
these three and belongs with them in sect. Lito-
phyllum
The chararieriiiks of M. retentipetala sug-
gesting the three species named are: small simple
stomatal crypts, a one-layered upper epidermis,
small flowers, tetramery, monoporous eglandular
anthers, a one-locular ovary with few ovules, and
a large hilum on the seed. Some of these characters
are not found in all three of the presumed allies,
and several have not yet been investigated in M.
latihila owing to lack of material.
Mouriri retentipetala differs from M. exadenia
in having higher, more numerous stomatal crypts,
pedicellate flowers, persistent petals, monoporous
caudate anthers, and a large hilum on the s
From M. monopora the new species departs in its
tetramery, triangular calyx lobes, and eglandular
anthers with a longer cauda and straight thecae.
From M. latihila, M. retentipetala varies in hav-
ing stellate foliar sclereids, short calyx lobes so that
the petals protrude from the calyx early in the
bud, and persistent petals.

Recent collections of M. gleasoniana from Cos-
ta Rica and Panama require reassessment of the
status of M. coibensis, a close relative of the former
species from the island of Coiba off the southwest
coast of Panama. When M. coibensis was de-
scribed, M. gleasoniana was known only from
Honduras to Mexico, and the differences between
the two taxa as then known were sharp. The new
material partly bridges the gap between them and
seriously weakens their separation. I believe real-
ities are best served viewing both as part of a
single variable species. As presently known, the
island plants are sl pasan and are re-
tained as a variety. Six major variables are in-
volved, as shown in Table 1. Plants of the complex
are yet to be found in Nicaragua.

Ovule numbers are relatively large in plants of
Costa Rica and the Panama mainland. In the one
flowering collection from Panama (Knapp & Huft
4424) and one of the two Costa Rican collections
(Hammel 9317), the large number of ovules ap-
parently results in an unusual placentation in that
the ovules in each locule are arranged on all sides
of the axile- ine placenta. These are the only
nown pl such an arrangement in sections
4 dur. 9 of subg. Mouriri.
A transition from a large number of ovules to
a small one raises the question of which state, if
either, represents the primitive condition. A similar
trend was found in M. guianensis, where the con-
clusion was that the greater number was primitive
(Morley, 1983). In M. gleasoniana the presence
of the larger numbers close to South America,
where the genus appears to have originated, with
the smaller numbers to the north, where the en-
vironment gradually becomes more extreme, sug-
gests that the same interpretation should be made
in this species. Throughout the range, the fruits
are 1-4(-5)-seeded; as in M. guianensis, many
ovules must therefore abort when a large number
is present before fertilization. Accordingly, those
plants with fewer ovules in the flower and thus less
wastage would be regarded as better adapted and,
in this case, more specialized. It would appear that
in increasingly extreme environments the demand
or floral economy becomes greater.
Mouriri longifolia (HBK) Morley. Until re-
cently, this species was known only from fruit-
ing material. A flowering collection has now
been made, so that the following addendum
to the description of the species can be given,
with illustrations (Fig. 5).

7.7 mm long to base of farthest pedicel measuring
along the axes and with 2 or 3 internodes in that
length; bracts 1.4-2.5 mm long, triangular or nar-
rowly so, mostly present at anthesis, deciduous
later. Axes of inflorescence, ovary, and calyx mi-
nutely puberulent. True pedicels 7-15 mm long;
calyx including inferior ovary 6.2-8.5 mm long,
campanulate; free hypanthium 2.2-2.7 mm long;
calyx lobes just before anthesis 2.1-2.4 mm long,
.o-3 mm wide, 3.8-4.1 mm long from the stamen
attachment, triangular with inverse-curved sides,
the calyx splitting 0-0.5 mm between the lobes at
anthesis. Petals ovate-oblong, ca. 10 mm long in-
cluding a basal claw ca. 3 mm long, 7 mm wide,
broadly acute at apex, erose toward the base. Fil-
aments 11-14 mm long; anthers 3-3.3 mm long;
thecae 2.8-3 mm long, dehiscing by apical slits;
gland 0.8-1 mm long, 2.1-2.3 mm from apex of
anther when measured from center of gland; cauda
0.6-0.8 mm long. Ovary 5-locular; placentae basal
in each locule, the ovules borne on all sides of a
short basal column, ca. 5 per placenta, ca. 25 in
all; style 17-22 mm long.
With the flowering material in hand it now be-
comes apparent that M. longifolia belongs in sect.
Apirangia. Specifically, the characters that place
it there are the tubular midrib xylem, filiform scler-
eids, Type III crypts like those of M. apiranga,
the lack of a hypodermis, the free calyx lobes with
the petals protruding from them early in the bud,
the anther shape which generally agrees with that
of the other species, the proximate position of the
placentae which are not widely separated, and the
position of the ovules on all sides of each placenta.

This species is identified more by its combination
of features than by any unusual characters. It is
allied to the other four species that have four locules
or placentas, numerous ovules, and (with one ex-
ception) hairs on the midrib. Its laterally fused
stamens occur in two members of this group of
four, V. plerocarpa and V. monadelpha. From all
of these the new species differs in having much
smaller leaves and flowers and only 15-16 ovules.
Three of the other four, V. monadelpha, V. or-
binaxia, and V. plerocarpa, have 36-48 ovules.
The fourth, V. pubescens, is closest in ovule num-
ber with 20-26, but the new species differs greatly
from that species by having small nearly glabrous
leaves, a nonindurated ovary wall, laterally fused
stamens, four locules, and a persistent style. The
remaining three species in the genus, V. guianen-
sis, V. orinocensis, and V. monantha, have one-
locular ovaries with 8-10 ovules and glabrous mid-
ribs. Because of its small leaves, small flowers, and
geographic proximity, a close relation of V. rorai-
mensis to V. orinocensis and the related Cuban
species V. monantha seems likely, although the
floral structure mostly does not sustain this view.
The small leaves, deep hypoderm, and persistent
style of the new species in particular suggest NV.
monantha, although the hypoderm of the former
differs in having abundant mucilage walls.
Ovules in Votomita and Mouriri vary from a
campylotropous type in which the ovule is bent at
a sharp angle from a short, broad placental at-
tachment at the chalazal end to half-anatropous,
and fully anatropous forms occur in Mouriri. In
V. pubescens and V. roraimensis, the ovules are
half-anatropous and are borne on an axile placenta,
the only known examples of such a combination
in the two genera. In Mouriri, half-anatropous
ovules occur only on axile-basal, free central, or
asal placentas. In V. pubescens, the ovules are
sessile laterally with extruded inner integuments
that appear to serve as internal stigmas (Fig. 7D).
Seeds are known in three species of Votomita:
V. monantha, V. pubescens, and V. roraimensis.
In V. monantha, which has free-central placen-
tation, the angular distance on the seed between
the micropyle and the broken chalazal strand is
about 94°, while in V. roraimensis and V. pubes
cens, with axile placentation, the angles are 60?
and 50? respectively.
In V. monantha the whole abaxial (outer) sur-
face of the seed is smooth, whereas in V. rorai-
mensis and V. pubescens the smooth part is narrow
and is broadest at or near the micropylar end (Figs.
6L, 7F). In none of these seeds is the smooth part
polished. Seeds of the latter two species resemble
superficially seeds found in Mouriri sect. Brevi-
pedillus; however, in that section the smooth area
is narrowest at the micropylar end and is usually
conspicuously widened at the opposite end nearest
the broken chalazal strand. I have no explanation
for the difference in shape.
The reason for the smooth area is unknown; it
may be that this is the part of the ovule first pushed
against the ovary wall as enlargement begins.
THE GENUS QUESTION
Partial generic differences between Votomita
and Mouriri in ovule and seed structure are sug-
gested by the above and may be summarized thusly:
(1) half-anatropous ovules on an axile placenta
occur only in some species of Votomita; (2) the
smooth area of the seed is unpolished in Votomita
but is polished in almost all species of Mouriri; (3)
in no known species of Votomita does the smooth
area cover all of the seed except for the hilum, as
it does in seeds of the subgenus Mouriri; and (4)
seeds of Votomita most closely resembling those
of Mouriri are found only in sections Acutiflos and
Brevipedillus of Mouriri subg. Taphroxylon. Seeds
of V. monantha somewhat resemble those of sect.
Acutiflos but lack the polished face and rugose
surrounding area of the seeds of that section. Seeds
of V. pubescens and V. roraimensis have narrow
smooth areas with surrounding rugose surfaces as
in Mouriri sect. Brevipedillus, but the smooth
parts differ in shape as described above.
e above considerations may affect present
generic divisions. The seed structure in V. rorai-
mensis and V. pubescens maintains the difference
between Votomita and Mouriri subg. Mouriri but
increases the resemblance between Votomita an
Mouriri subg. Taphroxylon.
It may be that the New World Memecyleae
should be regarded as consisting of three genera
or subgenera: Votomita, Mouriri, and Taphrox-
ylon. Absolute differences exist between all three
groups, the most between Votomita and subg.
Taphroxylon, the fewest between subgenera Ta-
phroxylon and Mouriri, thus supporting the pres-
ent disposition of these groups. Between Votomita
and subg. Taphroxylon the differences are those
of midrib xylem form, flower mery, hypanthium
development with accompanying features of sta-
men form, and the presence or absence of free
stone cells in the petals. Between Votomita and
subg. Mouriri the differences are the presence or
absence of free stone cells in the petals, and seed
structure; between subgenera Taphroxylon and
Mouriri the single absolute difference is that of

seed structure. On this basis Votomita is overall
more like subg. Mouriri than subg. Taphroxylon,
even though seed structure in Votomita is more
like that of the latter.
Because the above differences do not negate the
present arrangement of genera, I think any serious
effort to reconsider the generic divisions must await
more evidence. Seeds of more species of Votomita
should be examined, and detailed comparative stud-
ies of wood anatomy, karyotypes, and phytochem-
istry may be expected to aid in the evaluation.
When the similarities and dissimilarities between
the three are well known it can then be decided
how many of them should be assigned generic
status.

STUDY OF THE
FLORA OF RUCAMANQUE,
CAUTIN PROVINCE, CHILE:
Carlos Ramirez,’ Enrique Hauenstein,’
José San Martín* and Domingo Contreras?
ABSTRACT
The flora of forest, scrub, and grass communities was studied in Rucamanque, located near the city of Temuco,
Cautin Chile, in the central valley of south central Chile. Forty-six vegetation samples were made, an
collected intensively outside the sample areas. A
importance of each in the different vegetational communities, and their uses in industry, crafts, and medicine
ucamanque, ““The House of the Condor" in
Mapudungun, the language of the indigenous peo-
ple of this region (Ramirez-Sanchez, 1985), is a
valley located 12 km northwest of the city of Te-
muco, capital of the IX Region of the Araucania,
Chile (Fig. 1). The primitive forest vegetation of
this valley escaped destruction during last century's
process of colonization of central southern Chile
(Donoso, 1983) because it was protected as an
early watershed area for the drinking water for
Temuco (Magofke, 1985).
With the increase in population, water for the
city had to be drawn from other sources, principally
subterranean, so the state lost its interest in Ru-
camanque and offered it for sale in March of 1986.
Because of its value as a forest relict and its sci-
entific interest, several state and private institutions
and ecological organizations intervened to preserve
it from exploitation. Finally, the University of the
Frontera in Tem ie the legal owner, saving
the relict forest for science, education, and the
general public.
The present catalog of the flora of Rucamanque
was made during the time that the land was for
sale.
STUDY AREA
camanque is a small river valley oriented
southeast-northwest to the south of the Ñielol-
Huimpil hills (Magofke et al., 1986). Through it
runs Chivilcán Creek, which receives the water of
two small unnamed streamlets. Its elevation ranges
from 300 to 530 m. The area occupies about 525
ha, including some of the adjacent forests that
belong to private owners. The basin and slopes of
Rucamanque Valley are covered by native forest,
which is evergreen in the lower areas and partially
deciduous at higher elevations. In several places
the forest has been destroyed and secondary scrub
replaces it. In the higher slopes, originally of de-
ciduous forest, permanent grasslands of human
origin can be found. Small bogs, which we include
in the grassland formation, appear in open areas
on the edges of streams at the bottom of the valley.
The climate of the area is humid and temperate
with a Mediterranean influence (Di Castri & Hajek,
1976). The average annual rainfall is 1,400 mm
and the median annual temperature is 12°C. Rain-
fall is abundant in winter, and summers often have
one to two dry months, as shown in the climatic
diagram in Figure 1. Winter and spring frosts are
frequent. To this climate corresponds a subtropical
semideciduous forest type as natural vegetation
(Schmithüsen, 1956).
The Nielol- Huimpil hills comprise a tectonic unit
characteristic of the central valley of Chile and do
not connect with either the Coastal Ranges or with
the Andes. The red clay soil does show similarity
to the Coastal Range soils (Weinberger & Binsack,
1970). When cultivated or grazed, this soil is sub-
ject to erosion.
METHODS
The catalog of plant species of Rucamanque was
made from 46 vegetation samples taken using the

Braun-Blanquet (1964) phytosociological method
for the study of the local vegetation. Other plants,
collected outside the study quadrats, were added
to the collection. Eighteen samples were taken in
the forest, 20 in scrub vegetation, 6 in pastures,
and 2 in bogs. The vegetation contains the following
associations: Lapagerio—Aextoxiconetum punc-
tatii, Nothofago—Perseetum linguae, Fuchsio—
Chusqueetum quilae, Rhaphithamno- Aristote-
lietum chilensis, Chusqueetum coleu, Aristotelio—
Rubetum constrictae, Hyperico-Agrostidetum
castellanae, and Juncetum procerii (Oberdorfer,
1960; Ramirez, 1982; Hilldebrand, 1983).
The frequency of each species was estimated in
each plant association. The relative importance
value was calculated adding this frequency and the
average cover expressed in relative percentage of
each species in the different associations according
to the Wikum & Shanholtzer (1978) method. This
value was not determined for species collected out-
side the quadrats.
Nomenclature and phytogeographic origin of the
taxa were based on Marticorena & Quezada (1985)
and the family nomenclature on Cronquist (1981).
The common names are according to Munoz (1966).
Introduced species were classified using the Ger-
man flora by Rauh & Senghas (1968). The col-
lected species were kept in the herbarium of the
Institute of Botany, Austral University of Chile
(VALD).

Life forms follow the Raunkiaer system (Ellen-
berg & Mueller-Dombois, 1966). Vines, epiphytes,
and parasites were included under phanerophytes.
The interpretation of the biological spectrum was
based on Cain (1950)
Information was added on the present and po-
tential uses of the plants.
RESULTS AND DISCUSSION
The flora of the study area is made up of 203
species, of which 190 were inventoried in the 46
vegetation samples taken in the forest, scrub, and
grassland formations (Appendix I). The other 13
species were collected outside the sample quadrats.
The 203 species are distributed among 161 genera,
84 families, and 6 classes (Table 1). The class with
the greatest number of taxa was Magnoliopsida
(dicotyledons), which include almost 69% of the
species present in Rucamanque. Following these
are the Liliopsida (monocotyledons) with 42 species
(21%), and the Polypodiopsida (Filicinae) with 16
species (8%).
The best-represented family of the Magnoliop-
sida was the Asteraceae, with 18 genera and 25
species, amounting to 12% of the total. Next came
the Fabaceae with 4 genera and 9 species, the
Apiaceae with 6 genera and species, the Lamiaceae
and Rosaceae with 5 species each, and the Myr-
taceae, Proteaceae, and Scrophulariaceae with 4

Cyperaceae with 5, and the Juncaceae with 4
species. Among the ferns, the Hymenophyllaceae
presented 6 species, all of which were epiphytes
in the forest formation.
ORIGIN
Of the 203 species, 147 (72.41%) are native
and 56 (27.58%) are introduced (Table 2). This
high percentage of introduced weeds indicates a
strong human influence on the vegetation (Sukopp,
1969). The introduced species only belong to the
classes Magnoliopsida and Liliopsida, and make up
31.4% and 28.6% of each group, respectively. Of
course the greatest percentage of introduced species
is found in the shrub grassland formations, of an-
thropic and therefore secondary, origin (Ramirez,
1982). The evergreen forest of Aextoxicon punc-
tatum is the association least invaded by weeds.
The majority of the introduced species are origi-
nally European and of little grazing value (Mon-
taldo, 1975; Anazco et al., 1981).
LIFE FORMS
The biological spectrum of the study area was
constructed from 200 species; the remaining three
were mosses. In the epiphytic synusia that were
not considered, mosses are very abundant (Riveros
& Ramirez, 1978). The most-represented life form
was the phanerophytes with 80 species, repre-
senting 40% of the total. This life form abounds
in forest and scrub formations, occupying different
strata in the vegetation. Chamaephytes and cryp-
tophytes were the scarcest, with eight species (4%)
each. Hemicryptophytes appeared in about the same
numbers as phanerophytes, with 78 species, or
39%. Therophytes were represented by 26 species,
or 13%. The latter two herbaceous life forms were
abundant in grassy and scrub formations (Table 3
The biological spectrum here described (Fig. 2)
corresponds to a phanerophytic phytoclimate, typ-
x
ical of intermediate latitudes in temperate zones
(Cain, 1950). The relative abundance of hemi-
cryptophytes and therophytes is related to the de-
gree of anthropic intervention suffered by the orig-
inal vegetation. In the original vegetation, these
ife forms certainly were not as important.
This is confirmed by separating the native ele-
ments from the introduced for each life form (Table
4, Fig. 3). Only one of 80 phanerophytes is exotic.
The cryptophytes are all native. Among the cha-
maephytes and hemicryptophytes, the percentage
of introduced species is much higher, reaching
37.5% and 38.5%, respectively. Cryptophytes are
not very frequent, unlike the hemicryptophytes,
which contribute 30 exotic species. These perennial
cespitose herbs and rosettes are plants that accom-
pany man and do not characterize any particular
phytoclimate (Le Blanc, 1963). Their abundance
is due to destruction of forest and to grazing, which
impedes their replacement by more aggressive
woody species (Pessot & Montaldo, 1974).
The therophytes constitute a special case of
plants typical of dry climate or weeds of cultivated
areas. They act as pioneers in uncovered soil (Cain,
1950). Only 15% of the therophytes present in
the study area are native. This life form was scarce
in the original vegetation but invaded anthropo-
genic grasslands formed on eroded soils, where the
vegetational cover never reaches 100%. Thus,
therophytes are not typical of Rucamanque.
The phanerophytes, therefore, make up the most

search area, including trees, shrubs, epiphytes, and
Es (Table 5). Shrubs were very abundant,
28 species, 35% of all the phanerophytes.
This life form dominates the secondary scrub and
tends to invade degraded and abandoned pastures
or grassy areas (Ramirez et al., 1984a, 1985).
Twenty-two species of trees were present, or 27%
of the total.
Sixteen climbing plants flourish in Rucamanque,
making up 20% of the total. The most robust of
these, Hydrangea serratifolia, can have a stem
diameter of up to 15 cm. Climbers are typical of
forest and proliferate in secondary scrub where

FREQUENCY IN THE PLANT ASSOCIATION
Only two species were present in each of the
eight studied plant associations: Rubus constrictus
and Prunella vulgaris (Table 6). These are Eu-
ropean weeds, the first a spiny, semiclimbing shrub,
and the second, a chamaephytic herb. Both have
wide ecological ranges, colonizing any disturbed
site in central-southern Chile. Another European
species, Holcus lanatus, was found in seven of the
eight associations studied. In six associations, Plan-
tago lanceolata, another European herb, was found
along with Aristotelia chilensis and Eucryphia
cordifolia, two native woody species.
Native species with a frequency of five, that is,
which occur in five associations, are: Aextoxicon
punctatum, Luma apiculata, Baccharis race-
mosa, Lapageria rosea, Cissus striata, Boquila
trifoliolata, and Blechnum hastatum. The first
two are arboreal species of forests and scrubland;
the third is a small shrub fairly frequent in the
south of Chile. The remaining three are vines that

importance of these two shrubs, which belong to
disclimax communities, indicates the degree of an-

camanque. They invade areas when the forest has

Nothofagus obliqua show similar importance val-
ues. The former dominates in shrub communities
and the latter in partially deciduous forests of the
Nothofago—Perseetum. The next-lowest values
were found for Agrostis Bases, Chusquea co-

APPLICATIONS
The flora of Rucamanque offers many uses, some
of which are employed by the Araucarian Indians
(Mapuche) who populate Cautin Province. Chus-
quea coleu and C. quila are used in crafts and
for the construction of furniture and household
articles. To fasten pieces of these bamboos, “vo-
quis” (Boquila trifoliolata and Campsidium val-
divianum) serve as ties. Juncus procerus is used
to make mats. From Luma apiculata, tool handles
are cut, and the wood of Embothrium coccineum
is carved.
Applications as construction materials are im-
mannia trichosperma. Tannins for the leather tan-
ning industry are obtained from the barks of Persea
lingue and Weinmannia trichosperma. Many in-
dividuals of the latter species can presently be

found with the bark cut off, resulting
exploitation. Eucryphia cordifolia is valued for
domestic firewood, and for this reason the tree is
being cut so extensively that it risks local extir-
pation. Edible fruits grow on Lapageria rosea,
Chile's national flower. “Maqui cider" is made from
the berries of Aristotelia chilensis. Edible fruits
also grow on Gevuina avellana, Ribes trilobum,
Fragaria chiloensis, Ugni molinae, Fuchsia ma-
gellanica, and Peumus boldus. The fruits of Ru-
bus constrictus are used to make ja
The bark of Dasyphyllum e al-
legedly regulates blood sugar; Boquila trifoliolata
is applied for eye infections; Peumus boldus is
used for stomachaches and liver illnesses; an in-
fusion of Tristerix tetrandrus is ipe di to reduce
cholesterol in the blood. Solanum gay a
reputed febrifuge; Buddleja Borsa allegedly | helps
eal ulcers; and Equisetum bogotense is used as
a diuretic. The following introduced plants have
applications in popular medicine: Urtica urens as
an antirheumatic, Hypericum perforatum as a vul-
nerary, and Mentha rotundifolia and M. pule-
gium for the stomach.
The rhizomes of Dioscorea brachybotrya are
edible and high in starch. Maytenus boaria and
Chusquea quila provide excellent winter forage.

NOVELTIES IN THE
ORCHID FLORA OF
SOUTHERN VENEZUELA!
Gustavo A. Romero??
and Germán Carnevali?^
ABSTRACT
Six new orchids from Venezuelan Guayana are described and illustrated, including three species, Coryanthes
at
cataniapoensis, Catasetu
zii, and Catasetum parguaz
ybrid, Catasetum X dunstervillei,
three hybrids involve four sympatric Catasetum species with overlapping flowering
seasons that share Eulaema cingulata (Fabricius) as their main pollinator
This paper and others in preparation precede
the publication of a comprehensive treatment ‘a
the Orchidaceae of southern Venezuela for J.
Steyermark’s Flora of the Venezuelan oe
(Carnevali et al., in prep.). The taxa described here
belong to two of the most complex genera in the
Orchidaceae, Coryanthes Hook. and Catasetum
Rich. Species in these two genera are extremely
variable, and in the Venezuelan Guayana many
closely related species are sympatric or syntopic,
e pollinators, and have overlapping flowering
seasons; natural hybrids are common.
alf of the taxa proposed here are natural hy-
brids. The parentage of these nothospecies was
inferred from pollination data, phenological data,
and morphological characters. This approach has
its limitations, but one can postulate safely parent
species if a large number of specimens of the sus-
pected hybrid are examined, because, as Hurst
(1902) indicated, “In orchid hybrids of the first
generation single specific characters are inherited
in all degrees of blending, forming, on the whole,
a perfect series between the respective characters
of the two parents." In Catasetum x wendlingeri
Foldats, the parentage was confirmed by artificial
hybridization experiments (A. Pardo, pers. comm.,

alliance (Pabst & Dungs, 1975: 172). It differs
from C. callosum by having a subcordate labellum
and truncated basal callus, and it differs from C.

and a labellum with erect-patent lateral lobes. It is
further distinguished by flowering almost invariably
from the developing leaf shoot.

Etymology. Named in honor of G. C. K.
Dunsterville, who first illustrated this hybrid in his
series coauthored by L. A. Garay, Venezuelan
Orchids Illustrated.
This natural hybrid has been previously assigned
to Catasetum fimbriatum (Morren) Lindley (Dun-
qi & Garay, 1966: 42; 1979: 85; Foldats,
1970: 80). However, three lines of evidence reveal
C. x dunstervillei as distinct. First, northern South
America lies outside the known geographical range
of Catasetum fimbriatum: southeastern Brazil,
southwestern Bolivia, Paraguay, and northern Ar-
gentina (Bicalho, 1965; Dodson, 1978). Second,
typical C. fimbriatum from southern Brazil differs
considerably from Catasetum X dunstervillei in
having a column with long antennae; a long, apic-
ulate, acuminate clinandrium; an apiculate, fleshy
anther; and a labellum with the fleshy mid-lobe
projected forward (see Vasquez & Dodson, 1982).
Third, based on fragrance and pollinator data,
Catasetum Xdunstervillei cannot be assigned to
C. fimbriatum. Hills et al. (1972) showed that C.
fimbriatum is a poor fragrance producer with a
fragrance spectrum unlike any other species in the
genus. Moreover, the only known C. fimbriatum
pollinator is Eufriesea auriceps (Friese) (Pijl €
Dodson, 1966: 182). Catasetum X dunstervillei,
in contrast, produces a fragrance that attracts Eu-
laema cingulata, one of the pollinators of Catase-
tum discolor Lindley, C. longifolium Lindley, and
in general the C. maculatum Kunth complex (Wil-
liams & Whitten, 1983). Catasetum X dunster-
villei was also compared with C. fimbriatum var.
cogniauxii L. Linden, described from material pre-
sumably collected in Venezuela (Linden, 18954).
A plate in Lindenia (Linden, 1895b) and Cog-
niaux's sketches in the type sheet (BR, photo)
reveal Catasetum fimbriatum differing from C.
x dunstervillei in the characters presented above.
Dressler (1976) pointed out that Dunsterville
748, assigned here to Catasetum X dunstervillei
peia in Dunsterville & Garay, 1966: 42;
9: 85), was a hybrid between Catasetum pi-
d and C. discolor, but he never proposed a
binomial. Dressler's hypothesis is supported by two
lines of evidence. The flowers of C. x dunstervillei
are intermediate between Catastum pileatum and
C. discolor, and these two species are by far more
abundant than any other possible parent species

Orchid Flora of Southern Venezuela
found in the general area where C. X dunstervillei
has been collected, as indicated by plant sampling
and by the frequency of their pollinaria on euglos-
sine bees (G. A. Romero, unpubl. data). Further-
more, Catasetum pileatum and C. discolor share
euglossine bee pu and have overlapping
flowering season
Dodson d that Dunsterville 748 was a
hybrid between Catasetum longifolium Lindley and
C. macrocarpum Rich. ex Kunth. (Dodson, 1978),
based on plants collected in Dawa, Guyana (also
pictured in Tan, 1971, fig. 8). However, the plant
illustrated in Dodson (1978) differs from C. x dun-
stervillei in the pendent habit, the long and narrow
leaves, and the labellum morphology.
Catasetum X dunstervillei is similar to Cata-
setum Xissanensis Pabst (a natural hybrid be-
tween C. pileatum and C. longifolium, Pabst, 1975)
but is distinguished by the shorter and wider leaves
and the labellum with a V-shaped callus.
Catasetum X dunstervillei flowers from the ma-
ture pseudobulb from August to December. The
pollen donor in C. X dunstervillei is most likely C.
discolor: the large pollinia of C. pileatum could
not fit in the narrow stigmatic cleft of C. discolor.

Etymology. The specific epithet probably re-
fers to the rose and white flowers in the original
description.
Natural hybrids between Catasetum discolor
and C. longifolium were expected in the Vene-
zuelan Guayana: the two species are separated by
less than the flying range of euglossine bees (1-5
km), they share male euglossine bee pollinators,
Eulaema meriana (Olivier), E. bombiformes
(Packard), and E. cingulata (Fabricius), and they
have overlapping flowering seasons. Around Puerto
Ayacucho, Venezuela, the same species of Eulae-
ma bees have been caught carrying the very dis-
tinct C. discolor and C. longifolium pollinaria in
late February through May. The pollinaria of both
»
species are placed on the ventrum of the bees
thorax, but C. discolor pollinaria have a dark brown
stipe and a very small viscidium (narrower than
the involute stipe), whereas C. longifolium polli-
naria have a light brown stipe and a large viscidium
(wider than the involute stipe). Plants bearing flow-
ers intermediate between the two presumed parents
had been collected in the Venezuelan Guayana,
Guyana (Dodson, 1978), and Brazil (Mansfeld,
1932) and were assigned previously to Catasetum
discolor var. roseo-album (Hook.) Mansf. Dodson
(1978) suggested that this taxon may have resulted
from a natural cross between Catasetum discolor
and C. longifolium, but he never changed its no-
menclatural status to that of nothotaxon.
Catasetum X roseo-album is widespread in low-
land "morichales" (gallery forest communities
dominated by Mauritia flexuosa L.f.) in the north-
western Venezuelan Guayana, where it occupies
typical C. longifolium habitat, growing near the
crown on the stems of Mauritia flexuosa. It is also
found on Bactris sp., and on dead trees in sea-
sonally flooded forest.
The hybrid differs from C. longifolium by hav-
ing generally erect (vs. pendulous) habit; leaves 6—
20 cm long, 4-7 cm wide and generally 5-nerved
(vs. 15-150 cm long, 1-3 cm wide, and 3-nerved),
shortly apiculate, apically incurved (vs. obtuse and
flat) clinandrium of the staminate flower, and the
C. discolor-like pollinarium.
The hybrid differs from C. discolor in the epi-
phytic habit, generally arcuate to pendent stami-
nate inflorescence (always erect in C. discolor),
and deeply galeate, dorsally compressed labellum
of the staminate flower (shallowly concave and
globose in C. discolor). Pistillate flowers of the
hybrid are often distinguished by the deeply galeate
labellum (globose in C. discolor) but can vary be-
tween C. discolor-like to C. longifolium-like (deep-
ly saccate), ranging in color from light green (yel-
low-green in old flowers) to deep maroon. The
hybrid staminate flowers vary in color between
pinkish white to green, purple, orange, or maroon.
460 Annals of the
Missouri Botanical Garden
Catasetum X roseo-album flowers from the ma- — dulate-dentate. The hybrid differs from C. pilea-
ture pseudobulb from June to January. Pollen flow
between either parent is likely, as the pollinia of
both species are of similar size.

Etymology. Named after K. Wendlinger, who
cultivated the plant featured in the original de-
scription.
C. H. Dodson first proposed this natural hybrid
between Catasetum pileatum and C. planiceps
(quoted in Dunsterville & Uzcategui, 1981) based
on the floral morphology of the G. C. K. Dun-
sterville 1413 specimen cited above. Dodson, how-
ever, never proposed a binomial. Since then, plants
resulting from the artificial cross between the pre-
sumed parents flowered in the collection of A. Par-
do in Venezuela, and three more specimens of the
presumed natural hybrid were collected around
Puerto Ayacucho. Comnarison of the staminate
flower of the artificial hybrid with the holotype of
Catasetum wendlingeri and C. planiceps (K, pho-
to) showed it to be more similar to C. wendlingeri;
in fact, some of the hybrids were identical to C.
wendlingeri. Catasetum wendlingeri had been
treated previously as a synonym of C. planiceps
(Foldats, 1959; 1970: 97; Schweinfurth, 1967).
Catasetum X wendlingeri differs from C. plani-
ceps in the epiphytic habit and in the generally
larger staminate flower with the labellum apex
broadly patent or reflexed and the column with a
long, apicular clinandrium. Further, the staminate
flowers of the hybrid are sometimes resupinate (as
in G. C. K. Dunsterville 1413 and G. A. Romero
& L. Rojas 1201), or the margins of the labellum
are fimbriate (as in G. C. K. Dunsterville 1413,
illustrated in Dunsterville & Uzcategui, 1981),
whereas the staminate flowers of C. planiceps are
never resupinate and the margins crenate or un-
tum in the hooded labellum and the bilaterally
symmetrical antennae of the staminate flowers.
Catasetum X wendlingeri flowers from the de-
veloping leaf shoot from April to July. This hybrid,
as is its proposed parent species, is pollinated by
Fulaema cingulata. The pollen donor of the hybrid
is most likely Catasetum planiceps; C. pileatum
pollinia could not be inserted in the narrow stig-
matic cleft of C. planiceps.

NOVELTIES IN THE
LAURACEAE FROM
VENEZUELAN GUAYANA!
Henk van der Werff*
ABSTRACT
Eleven new species (Licaria n Ocotea flavantha, O. liesneri, O. glabra
"roatii, P. croizatii, and P. fluviatilis) are described. Ocotea julianii is
for Phoebe peint Phoebe areolatocostae is transferred to Persea, and Ocotea
o ulata, O. tomentosa,
published as a new name
steyermarkiana is transferred to Rhodostemonodaphne
, O. huberi, O. megacarpa, O.
During the preparation of the treatment of the
Lauraceae for the Flora of the Venezuelan Guaya-
na, a number of collections were found that ap-
peared to represent undescribed taxa. Most of these
collections were gathered during recent expeditions
and are of high quality. As can be expected, there
are, after completion of the family treatment, still
several sterile or fruiting collections that do not
match any of the known species from Guayana
and that represent additional or even undescribed
species. These species could not be included in the
treatment for lack of adequate collections.
In general, the Lauraceae in Venezuelan Guaya-
na are still undercollected. Of the 128 species
(Nectandra excluded; this genus will be contributed
by Dr. J. Rohwer), 55 are known only from one
or two collections, while an additional 13 are known
from three or four collections. This large number
of rarely collected species suggests that there are
still several additional species to be collected and
that our knowledge about Lauraceae in Venezuelan
Guayana is far from complete.
The available data show that about one-third of
the species (41 out of 128) are endemic to Guaya-
na. Of these 41, 31 species occur on the slopes
and summits of the tepuis, while 10 are lowland
species. The number of endemic lowland species
will likely diminish when adjoining Colombia and
Brazil are better explored, because I expect that
lowland species such as Ocotea tomentosa, Persea
fluviatilis, and Phoebe semecarpifolia, which oc-
cur near the borders with Colombia and Brazil, are
not restricted to the Venezuelan side of the borders.
w species, combinations, and the new
name are arranged in alphabetical sequence.

I am not certain if Licaria tomentosa has only
three staminodia; the staminodia present on the
cupule represent whorl II and are only present
when the tepals facing them have not fallen off.
The tepals in front of the stamens (whorl III) are
absent, and it is likely that staminodia representing
whorl I would have fallen off as well.
At present, Licaria tomentosa is known only
from the holotype in NY (with detached cupules)
and sterile isotypes in COL and F. Allen (1964)
identified and cited these specimens as Ocotea ro-
raimae Mez, a species with alternate leaves, four-
celled anthers, a canaliculate petiole, without to-
mentose pubescence, and lacking loop-connected
lateral veins. I consider O. roraimae now part of
O. aciphylla (Nees) Mez sensu lato.

of this group in the Venezuelan Guayana have a
wide distribution (O. glomerata (Meissner) Mez,
O. guianensis Aublet, and O. longifolia HBK),
but these species have light-colored or very dense
pubescence. The color of the indument and the
smooth upper leaf surfaces suggest a relationship
with the more restricted O. bracteosa (Meissner)
Mez, O. cujumary Martius, and O. canaliculata
(Rich.) Mez. These three species in Venezuela are
known only from the eastern parts of T. F. Delta
Amacuro and Estado Bolivar. Ocotea cujumary
can be readily identified by its double-rimmed cu-
pules; the other two species differ from O. flavan-
tha in their glabrous ovary and style and in the
absence of leafless, but inflorescences-carrying ter-
minal parts of the twigs. The swollen pedicel sup-
porting the cupule and the rather large (and still
immature) cupules are additional distinctive char-
acteristics. Differences in leaf shape are rather
subtle. Ocotea canaliculata has the petiole poorly
differentiated and lacks the weakly recurved leaf
base, while O. flavantha has an obvious petiole
and a slightly recurved leaf base. Ocotea bracteosa
has larger and wider (to 15 x 6 cm) and more
glaucous leaves than O. flavantha.

Ocotea glabra is known only from two collec-
tions from the summits of Carrao- and Caraurén-
tepuis. It is characterized by being completely gla-
brous, its (narrowly) obovate leaves, and its ve-
nation with lateral veins departing at almost 90?
from the midvein. This last-mentioned character
occurs also in O. wurdackiana Allen, a species
restricted to the tepuis of Estado Bolivar. Allen
(1964) cited the type collection of O. glabra as a
paratype of O. wurdackiana and described O.
wurdackiana as having hermaphrodite flowers.
Recent collections have shown that O. wurdack-
iana has unisexual flowers, like O. glabra. The
two species, although superficially similar, can be
separated as follows: O. glabra is entirely glabrous
and has the lower leaf surfaces smooth, while
wurdackiana always has a pubescent terminal bud,
the inner surface of tho tepals densely pubescent,

and the lower leaf
Ocotea glabra has its closest bie amon
the ten unisexual Ocotea species in the Venezuelan
Guayana that share glabrous twigs, leaves, and
terminal buds. Two of these have pubescent flowers
or inflorescences (O. myriantha (Meissner) Mez
and O. perrobusta (Allen) Rohwer) and are not
very closely related. Ocotea myriantha is a low-
land species, rather common in southern T. F.
Amazonas, whereas O. perrobusta is restricted to
Auyan-tepui, Estado Bolívar. The remaining species
in this group have a restricted distribution and are
known only from the upper slopes or summits of
one or two sandstone mountains. Three have rather
large, many-flowered inflorescences: O. crassifolia
(Sarven-tepui, Roraima), O. neblinae (Neblina),
and O. basirecurva (Serranía de Yutaje, Cerro
Coro-Coro). Short, almost spicate, and few-flowered
inflorescences, also strongly coriaceous leaves,
characterize the last large group of species. Several
t not all species in this group have glaucous,
clustered, almost sessile leaves, shiny upper leaf
surfaces, and lobed or toothed cupules. This group
can be subdivided into (1) species from Estado
Bolivar, characterized by immersed or elevated
costa and lateral veins but without a raised reticula-
tion (O. erectifolia (Allen) van der Werff, Cerro
Jaua; O. glabra van der Werff, Carrao-tepui and
Caraurén-tepui; O. roseopedunculata van der
Werff, Acopan-tepui), and (2) species from T. F.
Amazonas with weakly developed lateral veins and
raised reticulation on upper and/or lower leaf sur-
face (O. venosa Gleason, Cerro Duida, Marahuaca;
O. cowaniana Allen, Serrania Paru; O. huberi van
der Werff, Cerro Coro-Coro, Serrania Guanay).
Ocotea glaucophylla Moldenke, based on material
from Cerro Duida, is not well understood; to this
small-leaved species also belong collections from
Chimantá, revealing an unusual distribution pat-
tern. With the exception of O. glaucophylla, these
species are well defined by their inflorescence and
leaf characters (Fig. 3); they are also geographi-
cally separated, and the paucity of collections is
probably due to occurrence in inaccessible places.
The collection Maguire 33026 (NY) from Cerro
Guaiquinima belongs in this species group (it has
glabrous leaves, twigs, and terminal bud, and clus-
tered, glaucous, coriaceous, subsessile leaves) and
differs from the other species in its smooth upper
leaf surface; it is almost certainly undescribed, but
because it is sterile, I do not wish to describe it.

Ocotea huberi is restricted to the Departamento
Atures and Distrito Cedeño, along the border of
Estado Bolivar and T. F. Amazonas. Its closest
relative is O. venosa Gleason, a species only known
from the type collection from Cerro Duida and a
fruiting specimen from Cerro Marahuaca, both in
. Amazonas. The two species have similarly
id reticulation, toothed or lobed cupules, and
swollen fruiting pedicels. They differ in their leaf
bases, which are obtuse in O. venosa vs. rounded
to cordate in O. huberi, and in the much shorter
inflorescences of O. venosa. The types of O. venosa
(NY, US) do not have open flowers, and I have
not compared their floral details; I accept O. huberi
as a distinct species based on its striking leaf shape
and long inflorescences.
The group of species to which Ocotea huberi
belongs is characterized by unisexual flowers. The
MO sheet of Huber 11008 has two twigs, one in
young fruit, the other in flower. Dissection showed
the flowers to be staminate (anthers with well-de-
veloped locelli; pistil hollow). Thus, the flowering
and fruiting twigs on the type sheet probably came
from different plants, and I select the flowering
twig as the holotype. ipsias ee of O. huberi
are further discussed under O. gla
Ocotea julianii van der Werff, nom. nov. Based
on Phoebe steyermarkiana Allen, Mem. New
York. Bot Gard. 10(5): 74. 1964. TYPE: Stey-
ermark & Wurdack 921 (holotype, NY; iso-
types, F, MO).
Ocotea julianii was erroneously described as
belonging to the genus Phoebe by Allen. The large,
cup-shaped cupule excludes this species at once
from Phoebe, a genus in which the fruit is sub-
tended by a small cupule with the tepals usually
persisting. Leaf venation, the large cupule, and the
deep floral tube in old flowers all point to the Ocotea
aciphylla group (I have not seen good flowering
material). Because Allen already described Ocotea
steyermarkiana, a new epithet is needed when
Phoebe steyermarkiana is transferred to Ocotea.
The similarity between Ocotea julianii and
Phoebe tetragona (Meissner) Mez pointed out by
Allen (1964) is superficial. Fruiting specimens of
the latter species have a cupule typical of Phoebe,
and the leaves and flowers are glabrous. Distri-
bution also argues against a close relationship, since
P. tetragona is a cerrado species from Minas
rais, Brazil. I regard O. julianii as closely related
to O. revoluta Moldenke, a poorly known species
from Cerro Duida. This species differs in its nar-
rower, generally smaller leaves with revolute mar-
gins and in its smaller, funnel-shaped cupules; both
species belong to the O. aciphylla group.

slightly revolute, both surfaces dull. Venation pin-
nate, lateral veins 5-7 pairs, arching upwards and
disappearing near the margin, midvein and lateral
veins immersed on upper surface, raised on lower
surface, the lower surface with a slightly raised,
fine reticulation, this less visible on the upper sur-
face. Petioles glabrous, 1.5-2 cm long, somewhat
canaliculate. Inflorescences glabrous, ca. 10 cm
long, shorter than the leaves, paniculate, the lower
branchlets with 2-5 flowers, otherwise flowers sin-

Fruits unknown.
Although Ocotea liesneri, known only from the
type collection, is in all vegetative parts glabrous
like Ocotea erectifolia and allies, these species are
probably not closely related. Ocotea liesneri differs
from the O. erectifolia group, for instance, by
having well-developed petioles, a rather lax inflo-
rescence (comparable to but smaller than that of
O. basirecurva), relatively long and pubescent fil-
aments, and flowers apparently hermaphroditic.
The last-mentioned character, difficult to ascertain,
needs verification from additional collections. Oco-
tea liesneri seems quite isolated. In the Venezuelan
Guayana, the number of hermaphroditic Ocotea
species is not great; most belong to the O. aci-
phylla group, which always has pubescent flowers
and a quite different venation, and the O. oblonga
group, which has entirely different leaves. The
remaining species are also isolated and possess some
striking characters; they include O. rubra Mez, O.
cymbarum esmeraldana Moldenke, and
O. fasciculata (Nees) Mez.

shape, venation, canaliculate petioles, and the ini-
tially deep cups all point to the Ocotea aciphylla
group. Within this group (and within the genus
Ocotea), the large fruits and large, shallow cupules
are unmatched, and O. megacarpa is solely de-
scribed on the distinctiveness of its fruits and cu-
pules. In the Ocotea aciphylla group, O. julianii
also has large fruits (3.5 x 3 cm) and cupules (ca.
3 cm wide). However, in addition to its smaller
fruits and cupules, O. julianii differs in its rounded
to subcordate leaf bases, short, thick petioles, and
blunt to rounded leaf apices. Ocotea megacarpa
is in leaf shape (but not in indumentum) very similar
to O. aciphylla (Nees) Mez s.l.,
lowland populations in T. F. Amazonas, which have
been identified as O. costulata (Nees) Mez in the
past, but this species has appressed pubescence,
cupules to 2 cm wide, and fruits to 2.5 cm long.

Ocotea roseopedunculata is restricted to Aco-
pán-tepui and is currently known from only two
collections. Its nearest relative is Ocotea glabra,
known from Carrao and Caraurén-tepuis in Estado
Bolivar. These two species are best separated by
their leaf characters: O. roseopedunculata has
elliptic leaves with mostly ascending lateral veins,
while O. glabra has (narrowly) obovate leaves with
the lateral veins leaving the midrib under a blunter
angle and more rounded leaftips. In sme ae there
are some small floral differences: in O. glabra the
filaments and anthers of the outer stamens are
about equally long and the pistillode is ca. 0.8 mm
ong; in O. roseopedunculata the anthers are sub-
sessile and the pistillode is smaller, 0.3 mm long.
The two species share ridged stems, conspicuous
leaf scars, almost spicate, few-flowered inflores-
cences, and a tendency toward clustered leaves.

Ocotea tomentosa is known only from the upper
drainage of the Río Negro between Maroa and San
Carlos de Rio Negro. Although the area around
San Carlos de Río Negro has been reasonably well
explored, O. tomentosa has only been collected
there twice (both collections from the same marked
tree) and is apparently rare. It is very likely present
in Colombia and can be expected in Brazil.
The angled twigs, somewhat clustered flowers
and, above all, scarce pubescence on the tepals in
comparison with that on the inflorescence point to
the Ocotea leucoxylon group as the closest rela-
tives. None of the species in that group has leaves
with dense abaxial tomentum or such persistent
tepals in the fruiting stage; moreover, O. tomentosa
lacks the white lenticels on the cupule that so
readily identify the O. leucoxylon group.
Persea areolatocostae (Allen) van der Werff,
comb. nov. BASIONYM: Phoebe areolatocostae
C. K. Allen, Mem. N.Y. Bot. Gard. 10: 75
1964.
The type collection of Phoebe areolatocostae
has buds and immature fruits. However, the fruits
are diseased; the relatively long petioles, leaf shape,
and leaf reticulation all point to the genus Persea.
The equal tepals are a character infrequently found
in Persea; P. americana and a few related species
share this character, but P. areolatocostae is prob-
ably not related to those species. In my opinion,
the relationship is with a small group of species
characterized by equal tepals, a small, round fruit,
and persistent tepals in the fruiting stage. This
group includes the neotropical P. steyermarkii, P.
rigens, P. silvestris, and a few additional, as yet
undescribed, species. It is not yet clear to which
degree this group is related to the Asian Persea
subg. Machilus.

Persea croatii is known from only one collection
from the upper slope of Cerro Neblina. The pu-
bescent style and the few apical hairs on the ovary
place it in Kopp's (1966) section Aurataea, which
includes two other species from the Venezuelan
Guayana. Persea grandiflora, known from the
lower slopes of Cerro Neblina, differs in having
larger flowers, prominently raised lateral veins on
the lower leaf surface, ovate (vs. elliptic) leaves,
and much denser pubescence. Persea maguirei
differs in having smaller leaves, denser pubescence
croatii differs in its sparser, noncupreous pubes-
cence on the lower leaf surface and its noncupreous
pubescence on flowers and inflorescence.

In Kopp's (1966) revision of the neotropical species
of Persea, it keys to section Heteranthera because
the stamens of whorl III are sterile. Within that
section, it is closest to P. meridensis, a poorly
known Andean species, which differs in its ferru-
ginous pubescence, pedicelled flowers, and solid
twigs. Unusual characters of P. fluviatilis are the
subequal tepals, hollow twigs, clustered leaves, dif-
ference in pubescence between the young and old
twigs, and swollen pedicels in fruit. Because many
of the neotropical Persea species are infrequently
collected and are poorly known, close relatives of
this distinctive species have not been pinpointed.
The swollen pedicels in fruit are a very unusual
feature, but because there are only two fruiting
collections known, it is possible that this condition
is caused by a disease and is not typical for the
species. At the time of her revision Kopp had only
a fruiting collection of this species at hand, which
she cited as P. nivea Mez, a species that does not
occur in Venezuela.

ranged in an arc, not in two superposed rows. A
study of the available collections of O. steyer-
markiana shows that this species has all the char-
acters of Rhodostemonodaphne, and therefore a
new combination is made. I did not find that the
outer stamens have distinct filaments and that the
anther cells are arranged in two rows, as Allen
described and illustrated. Pubescence and inflores-
cence type suggest that RA. steyermarkiana is
closely related to R. celiana (Allen) Rohwer and
ndlicheria vinotincta Allen, both endemic to the
Venezuelan Guayana. I include two collections from
Cerro Sarisarinama, cited by Bernardi in Steyer-
mark (1976) as O. celiana Allen and O. ferruginea
(Meissner) Mez, in R. steyermarkiana.

The Miconieae Triana (Melastomataceae) are a
diverse tribe of ca. 30 neotropical genera, including
characterized, often difficult to discern, and defined
quite arbitrarily (Cogniaux, 1891; Macbride, 1941;
Gleason, 1932, 1958; Wurdack, 1972). In order
to clarify relationships within this large and com-
plex group, a preliminary cladistic analysis of the
axillary-flowered taxa of Miconieae was conducted
as reported here
Within the Miconieae, the inflorescence may be
either terminal or lateral. Plants with terminal in-
florescences have hapaxanthic shoots in which the
apical meristem of the shoot becomes wholly trans-
formed into a flowering axis after a period of veg-
etative growth, while plants with axillary inflores-
cences have pleonanthic shoots in which the apical
meristem continues its vegetative activity while
producing lateral flowers or inflorescence axes (see
Judd, 1986a; a UN Inflorescence po-
sition, along wit at t f growth
architecture, has been shown to be a valuable taxo-
nomic character in the tribe and is usually uniform
within sections or genera (Judd, 1986a).
The axillary-flowered condition is likely a de-
rived state within the Miconieae because nearly all
members of the Merianieae show terminal flowers.
The latter tribe is a reasonable outgroup taxon
considering possible tribal relationships suggested

Miconieae
by J. Wurdack (Welle & Koek-Noorman, 1981).
The same conclusion would be reached through
the use of a generalized melastomataceous out-
group and the tree counting algorithm of Frolich
(1987), since terminal cymose inflorescences are
the strongly predominant condition within non-Mi-
conieae melastomes. Terminal inflorescences occur
in over 80% of non-Miconieae genera, and strongly
predominate in all tribes except the Blakeeae Benth.
& Hook. f. In addition, Weberling (1988) noted
that all melastomes show monotelic inflorescences,
with the basic form being a pleiothyrsoid termi-
nating a leafy shoot. In this study the monophyly
of the axillary-flowered Miconieae was accepted as
a useful preliminary hypothesis and a cladistic anal-
ysis of these taxa was conducted. The results of
this analysis are then used to suggest generic re-
alignments and to reevaluate the preliminary hy-
pothesis of monophyly of the axillary-flowered taxa.
CLADISTIC ANALYSES
METHODS
The cladistic analyses were conducted using the
Wagner parsimony algorithm (with global branch-
swapping and multiple parsimony options) of the
PAUP (i.e., Phylogenetic Analysis Using Parsi-
mony, Version 2.4; Swofford, 1985) package of
computer software.
Fifteen Evolutionary Units (EUs) were used in
most of the analyses (Table 1), based on a survey
of ca. 370 herbarium specimens representing 150
species (and supplemented, where possible, by the
addition of information from recent taxonomic
studies). Several taxa also were studied during the
course of fieldwork in Haiti, the Dominican Re-
public, Puerto Rico, and Jamaica. In some anal-
yses, an additional EU representing either a gen-
eralized terminal-flowered taxon or Clidemia sect.
Miconiopsis Cogn. was used. Although terminal-
flowered, Clidemia sect. Miconiopsis has been
considered to be related to the other sections of
Clidemia included in this study, and its inclusion
in a few analyses was designed to test this hypoth-
esis. The inclusion of a generalized terminal-flow-
ered taxon in some analyses was designed, in a
very preliminary way, to evaluate the hypothesis
that the axillary-flowered Miconieae are monophy-
letic. Placement of this generalized terminal-flow-
ered taxon is considered very tentative because
this EU is extremely heterogeneous, making the
determination of its ancestral character states prob-
lematic (see Table 1).
Forty-two characters were used and assigned
plesiomorphic (ancestral: scored as 0) and apo-
morphic (derived: scored as 1) states (Table 1).
Apomorphic features used in the computer analyses
are listed below. Nearly all characters were polar-
ized using the Merianieae as an outgroup, with
character states uniformly found (or, for a few
characters, those states most commonly repre-
sented) in the out-group considered plesiomorphic
(Stevens, 1980; Wheeler, 1981; Wiley, 1981;
Maddison et al., 1984; Frolich, 1987). When EUs
are polymorphic for a given character, an estimate
of the ancestral condition was made. The states of
a few characters were unknown for certain taxa,
and these are scored as “missing data," indicated
by a “?” in the data matrix (Table 1). Trees were
rooted by using a hypothetical ancestor with all
characters scored as plesiomorphic.
APOMORPHIC CHARACTERS
1. Stems quandrangular and 4-winged/ ridged;
plesiomorphic condition: stems + terete. Quadran-
gular stems are considered an autapomorphy of
Killipia Gleason and occur in K. quadrangularis
Gleason (the type species). However, two other
species have terete stems, and the ancestral con-
dition within Killipia is not known. A coding of
"0" for this EU would not affect the analyses
because the feature is autapom i
2. Growth pleonanthic Lr plesio-
morphic condition: growth hapaxanthic (determi-
nate). (See character 12.)
3. Megastyloid crystals present; plesiomorphic
condition: only small styloids and/or druse crystals
present. (See character 4.)
4. Crystals exclusively druses; plesiomorphic
condition: small or large styloids and druse crystals
present. The polarity of characters 3 and 4 was
determined by using the Crypteroniaceae (Dahl-
gren & Thorne, 1984) as an outgroup (see dis-
cussion in Johnson & Briggs, 1984; Vliet et al.,
1981). This family, which is closely related to the
Melastomataceae, contains genera with druses and
with small styloids (Baas, 1981), and this crystal
complement is taken as the ancestral condition in
melastomes. It is likely that megastyloids have
evolved in a few lineages (sometimes with the loss
of druses), while styloids have been lost in other
lineages, resulting in druses being the only crystal
type in those groups. That styloids and druses are
known from more distantly related families of Myr-
tales, such as Myrtaceae and Combretaceae (Vliet
& Baas, 1984) supports this polarity. Variation in
crystal complement within the Merianieae is poorly
known.

Miconieae
morphic condition: elongate multicellular hairs
present, often strigose. Mecranium Hook. f. an
Killipia are unique in lacking a well- da
indumentum. A few species of Loreya DC.,
L. ovata Berg ex Triana, L. arborescens Gann
and L. nigricans Triana, lack such hairs as
wei je (in press) hypothesized the loss of
strigose hairs to be a synapomorphy of a species
group within Loreya. Thus, the presence of such
hairs is considered the ancestral condition within
the genus.
6. Multicellular hairs elongate with radiate to
stellate-globular basal portion (or clearly derived
types); plesiomorphic condition: multicellular hairs
various, but not as above. This distinctive hair
morphology is much modified (see discussion, and
Judd, 1986b) in a few species, but such extremes
are connected by intermediate types, sometimes
even on the same plant.
7. Multicellular hairs minute, globular, and un-
branched to irregularly branched and matted (not
strigose); plesiomorphic condition: multicellular hairs
various but not as above. This character is limited
to Mecranium (including Ekmaniocharis Urban)
and Ossaea acuminata The feature is im-
portant in determining that Mecranium spp.,
saea acuminata, and Ekmaniocharis crassinervis
Urban form a monophyletic group but does not
help in inferring relationships among the EUs.
8. Multicellular hairs conspicuously stellate (with
stalk and elongated arms); plesiomorphic condition:
multicellular hairs various but not as above. In
these analyses this feature is considered an autapo-
morphy of Clidemia sect. Miconiopsis. Very sim-
ilar hairs occur in many terminal-flowered species,
., Miconia sects. Jucunda (Cham.) Naudin and
Tamonea (Aublet) Cogn.
9. Leaves clearly anisophyllous; plesiomorphic
condition: leaves isophyllous or nearly so ew
specialized species of Clidemia sect. Sograt (DC.)
ogn. have anisophyllous leaves. The isophyllous
condition is considered ancestral within Clidemia
sect. Sagraea, following a preliminary analysis of
variation within the group.
10. Leaves with pair of pouchlike formicaria at
base of blade; plesiomorphic condition: leaves lack-
ing formicaria. Similar ant-domatia that occur in
terminal-flowered taxa, e.g., Tococa Aublet, Cli-
demia D. Don, Myrmidone Mart., probably evolved
independently (see discussion). Ossaea bullata (Pil-
ger) Gleason, possibly a member of the Sagraea
group, has been reported to possess similar for-
micaria (Whiffin, 1972).
11. Cuticle of abaxial leaf epidermis papillose;
plesiomorphic condition: epidermis nonpapillose.
Renner (in press) pointed out that this feature cor-
relates well with cuticle thickness and suggested
that the character has important ecological con-
sequences.
12. Inflorescences axillary (in leaf axils or at
nodes on old wood); plesiomorphic condition: inflo-
rescences terminal. Terminal cymose inflores-
cences (as discussed above) occur in over 80% of
genera within non-Miconieae melastomes. Thus,
proliferating inflorescences (in which the terminal
axis returns to vegetative growth, producing axil-
lary buds that develop vegetative branches instead
of flower-bearing paracladia—see Weberling, 1988)
are considered derived. The process of proliferation
results in a vegetative shoot in which the flowers
are borne in axillary cymose paracladia. Delayed
anthesis of the paracladia can even result in cau-
liflory.
13. Inflorescences
condition: inflorescences cymose. Although fasci-
cles occur in a few species of Loreya, Clidemia
fasciculate; plesiomorphic
sect. Sagraea (including axillary, 4-merous species
of Ossaea DC.), and the 5-(6-)merous species of
Ossaea, cymose inflorescences are considered to
be the ancestral condition in these groups. Renner
(in press) also considered fasciculate inflorescences
to be derived within Loreya.
14. Flowers more or less sessile; plesiomorphic
condition: flowers pedicellate.
15. Flowers 4-merous; plesiomorphic condition:
flowers other than 4-merous. (See character 16.)
16. Flower parts frequently more than 5; ple-
siomorphic condition: flowers 4- or 5-merous. Gen-
erally, 5-merous flowers are considered primitive,
with higher and lower floral numbers treated as
derived. Henriettea DC. and Loreya contain a few
species with numerical plans greater than five, while
Henriettella Naudin and Kirkbridea Wurdack
sidered ancestral. Renner (in press) considered flo-
ral numbers greater than five to be derived and
used this feature to link some species of Loreya
with Bellucia Raf. The ancestral condition in Kirk-
bridea is in doubt; however, recoding the state of
this EU as “1” for this character does not change
the topology of the discovered cladograms.
17. Flowers small; plesiomorphic condition:
flowers moderate to large.
18. Hypanthium strongly ribbed; plesiomorphic
condition: hypanthium nonribbed. This character
is an autapomorphy of Clidemia sect. Calophy-
soides Cogn.
19. External calyx lobes more or less conspic-
uous and well developed; plesiomorphic condition:
external calyx lobes absent or inconspicuous.
20. External calyx lobes absent; plesiomorphic

condition: external calyx lobes present. Some species
of Henriettella have lost external calyx lobes in-
dependently of the loss in Loreya, Bellucia, and
Myriaspora Is was determined because it
is evident that Henriettella evolved out of a group
within Henriettea, which has external calyx lobes.
21. Internal calyx lobes very elongate and
closely associated with external lobes; plesiomor-
phic condition: internal calyx lobes not elongate,
variously developed but not closely appressed to
internal lobes. This feature is an autapomorphy of
Killipia.
22. Internal calyx lobes connate into a mem-
branous, dome-shaped, apiculate cap that ruptures
irregularly at anthesis; plesiomorphic condition: in-
ternal calyx lobes free. This character is an aut-
of Mecranium (including Ekmani-
Although Ossaea acuminata has
somewhat caplike calyx lobes, they are only par-
tially connate. The internal calyx lobes are free
and imbricate at their extreme apices. This species
is included within the Mecranium EU since it has
the other apomorphies of this clade (characters 7,
19, and 32; see discussion).
23. Internal calyx lobes circumscissilly dehis-
cent (and noncalyptrate); plesiomorphic condition:
internal calyx lobes more or less persistent, or if
circumscissile, then calyptrate. This character is
considered an autapomorphy of Clidemia sect. Mi-
included within the generalized terminal-flowered
taxon).
24. Buds closed, with thick triangular calyx
lobes that cover bud up to the final stage prior to
anthesis (and sometimes fused into a cap); plesio-
morphic condition: buds open, calyx lobes of vari-
able shape and thin, the petals exposed much before
anthesis. This feature is an autapomorphy of Bel-
ucia
25. Internal calyx lobes reduced to a more or
less smooth rim; plesiomorphic condition: internal
calyx lobes clearly evident. This is a noninformative
character (see Table 1) because it is found only in
a few derived Vll within Henriettella and Cli-
demia sect. Sagraea.
Teas de lobes fused into a conical,
apically closed calyptra and conspicuously strigose;
plesiomorphic condition: internal calyx lobes non-
calyptrate (or if so, then not as above). This is an
autapomorphy of Myriaspora.
27. Internal calyx lobes fused into an apically
open cap (opening into sepal-like segments or cir-
cumscissilly); plesiomorphic condition: internal ca-
yx lobes noncalyptrate (or if so, then not as above).
This feature is limited to Llewelynia Pittier and a
few (probably related) species of Henriettea (see
discussion).
. Calyx a cap open at apex and falling off
by circumscissile slit; plesiomorphic condition: ca-
lyx not open-calyptrate, or if so, then opening by
longitudinal slits into triangular sepal-like segments.
This character is an autapomorphy of Llewelynia
and is a further specialization of character 27.
29. Petals narrowly triangular and more or less
acute at apex; plesiomorphic condition: petals ovate
to elliptic (or obovate) with blunt to more or less
acuminate apices. Preliminary analyses of variation
within Mecranium (including Ekmaniocharis) and
Clidemia sect. Sagraea (including axillary, 4-mer-
ous species of Ossaea) have led to the conclusion
that ovate to elliptic petals with more or less acu-
minate to blunt apices constitute the ancestral con-
dition within these groups. Obovate petals have
evolved within a group of Mecranium species. It
is noteworthy that Ossaea acuminata, a narrow-
petaled species, is a sister species to Mecranium
amygdalinum (Desr.) C. Wright in Sauv., a fairly
blunt-petaled species (Skean, in prep.).
30. Petals with a dorso-apical tooth; plesio-
morphic condition: petals lacking a dorso-apical
tooth. This feature occurs in a few species of Cli-
demia sect. Sagraea (including the species of Os-
saea with axillary, 4-merous flowers) and in the
r 6-merous species of Ossaea. A scoring of
«p is this character in these two EUs does not
alter their placement in relation to the very dif-
ferent Henriettea group.
31. Petals usually pubescent, sometimes only
with very few hairs near apex; plesiomorphic con-
dition: petals glabrous (or with a single apical hair).
Hairs on the petals have been lost in a few species
of Loreya and Bellucia.
2. Androecial fringe present; plesiomorphic
condition: androecial fringe absent. This feature is
a strong and consistent synapomorphy of Mecra-
nium species, including Ekmaniocharis crassiner-
vis and Ossaea acuminata.
. Anthers with two well-developed dorso-bas-
al aan: plesiomorphic condition: anthers
various but lacking two well-developed dorso-basal
projections.
4. Anthers usually robust and fleshy, opening
by one or two minute pores; plesiomorphic con-
dition: anthers not robust and fleshy, various.
35. Anther sacs basally bifurcate, i.e., sagittate;
plesiomorphic condition: anther sacs not bifurcate
at base.
36. Anther sacs more or less wrinkled; plesio-
morphic condition: anther sacs smooth. The best
expression of this feature is in Maieta Aublet.
37. Stamens numerous, i.e., more than twice

Miconieae
the number of petals; plesiomorphic condition: sta-
mens twice the number of petals. This is an aut-
apomorphic character of Llewelynia.
38. Stigma very conspicuously and radiately
ridged; plesiomorphic condition: stigma not radiate-
ly ridge
39. Piscenis highly divided; plesiomorphic con-
dition: placenta undivided or nearly so. This is an
autapomorphy of Myriaspora.
40. Fruit a berry; plesiomorphic condition: fruit
a capsule.
41. Chromosome number of n = 28; plesio-
morphic condition: n — 17 (or 15, 20). (See char-
acter 42.)
42. Chromosome number of n — 15, 20; ple-
siomorphic condition: n — 17 (or 28). The terminal-
flowered Miconieae were used as a generalized out-
group for the determination of polarity of the in-
completely known characters 41 and
RESULTS
Initial computer runs using the entire data set
for the 15 axillary-flowered EUs resulted in the
discovery of 100-- equally parsimonious trees (but
only 15 different topologies when multi-furcations
are taken into account), all with a length of 28
steps and a consistency index of 0.714 (or 48 steps
and consistency index of 0.813 when autapomor-
phies and uniform characters were included). The
strict consensus tree resulting from this analysis is
presented in Figure 1B. In addition a tree indicating
character state changes is presented (Fig. 1A). This
tree is preferred due to its pattern of character
variation, especially the linking of Mecranium and
Clidemia sect. Sagraea on the basis of 4-merous
flowers (15), and the linking of Henriettea, Hen-
riettella, and Llewelynia on the basis of fasciculate
inflorescences (13). The relationships of the EUs
representing Loreya, Bellucia, Myriaspora, Hen-
riettea, Henriettella, and Llewelynia did not vary
in any of the trees generated by PAUP. In addition,
Kirkbridea consistently linked with Henriettea,
Henriettella, and Llewelynia, in some trees as the
cladistically basal member of this clade, in others
as the sister group of Henriettella. In all trees, the
EUs representing Maieta, Clidemia sect. Calo-
physoides, and Clidemia juruensis (Pilger) Glea-
son were always joined, and Huilaea Wurdack was
always the basal member of the clade representing
taxa with only druse crystals. Thus the large num-
ber of generated trees is due to the numerous
possible topologies among the remaining EUs in
the analyses, i.e., Mecranium (including Ekmani-
ocharis and Ossaea acuminata), Clidemia sect.
Sagraea (including Necramium Britton and axil-
lary 4-merous species of Ossaea), Killipia, and
Pentossaea, here described to include the axillary-
flowered, 5-merous (or less commonly 6-merous)
species of Ossaea
Thus, several analyses were conducted using just
those EUs possessing only druse crystals (i.e., top
eight EUs listed in Table 1) with characters not
pertaining to this complex deleted. These analyses
generated 45 equally parsimonious trees (but com-
prising only seven different tree topologies) of 11
steps and with a consistency index of 0.727 when
all characters were weighted equally (or of 25 steps
and a consistency index of 0.880 when autapo-
morphies and uniform characters were included).
However, when the apomorphy of 4-merous flowers
was stressed (weighted by 2, as seems reasonable,
since this character is quite uniform within EUs
under investigation), only 15 trees (representing
only two topologies) were produced, all with 12
steps and a consistency index of 0.750 (or of 26
steps and a consistency index of 0.889 when aut-
apomorphies and uniform characters were includ-
ed). The consensus tree resulting from the analysis
in which all characters are weighted equally is
identical to that produced in the analysis of all
axillary-flowered taxa (Fig. 1B). Both cladograms
resulting from the weighted-character analysis are
given in Figure 1C and D
When an EU representing a generalized ter-
minal-flowered taxon is included in the analysis,
over 100 equally parsimonious trees were found,
all with a length of 32 steps and a consistency
index of 0.688 (or of 50 steps and a consistency
index of 0.780 when autapomorphies and uniform
characters were included). These trees are very
similar to those generated in the analyses involving
only axillary-flowered taxa (Fig. 1), and the four
different topologies involving their basal branches
are presented in Figure 2, illustrating the various
positions of the genus Huilaea and a generalized
terminal-flowered taxon. When Clidemia sect. Mi-
coniopsis (another taxon producing terminal inflo-
rescences) is included in the analysis, many trees
are again generated (of 55 steps and a consistency
index of 0.745, including autapomorphies), all link-
ing this entity with either Killipia or a clade con-
taining Killipia, Clidemia sect. Sagraea, and
Mecranium.
DISCUSSION
The cladograms presented in Figures 1 and 2
indicate that the axillary-flowered Miconieae are
divided into two major clades. The first is composed
of those taxa containing megastyloids (3) in their
leaf and stem tissues (often with druse crystals as
well) and usually possessing slightly pubescent pet-
als (31). The group also generally has distinctly

pedicellate flowers. This clade may be divided into
two clearly marked subgroups based on vegetative
and reproductive characters. Loreya, Bellucia, and
Myriaspora are united by the synapomorphies of
flowers lacking external calyx lobes (20), possessing
robust fleshy anthers (34), an expanded and ra-
diately ridged stigma (38), and a chromosome num-
ber of n = 15 or 20 (42). In contrast, Henriettea,
Henriettella, Llewelynia, and Kirkbridea form a
clade based upon the presence of multicellular stri-
gose hairs with a stellate, radiate, irregularly
branched, or suprabasally expanded base, or hair
types clearly modified from these conditions (6),
petals with an apical apiculum on the abaxial sur-
face (30), and a chromosome number of n — 28
(where known, 41). Kirkbridea likely is cladisti-
cally basal in this group, with Henriettea, Hen-
riettella, and Llewelynia being united by the ad-
ditional synapomorphy of fasciculate inflorescences
(13). (It should be noted that parallelism in flower
size (17) occurs within these genera, which is not
surprising considering the variability of this feature
within the tribe. Linking Kirkbridea and Henriet-
tella on the basis of this character is considered
implausible.)
The remaining taxa included in the analysis form
a second clade based on the following synapomor-
phies: presence of only druse crystals in leaf and
stem tissues (4), small more or less sessile flowers
(17, 14), and usually well-developed external calyx
lobes (19). The extremely isolated genus Huilaea
probably is basal within this clade (Fig. 1A, B)
because it shows only the synapomorphy of exclu-
sive presence of druse crystals (4), having large
and clearly pedicellate flowers. The relationships
among the taxa comprising this clade are not well
resolved. However, it is clear that Maieta, Cli-
demia sect. Calophysoides, and C. juruensis form

a monophyletic group based on the presence of
morphologically very similar pouchlike ant-domatia
(formicaria) at the base of the leaf blade (10) and
wrinkled anthers (36). In addition, Maieta and
Clidemia sect. Calophysoides have anisophyllous
leaves (9). If the character of 4-merous flowers is
stressed, then Mecranium is probably most closely
related to Clidemia sect. Sagraea, and the two
may be linked by this feature (15). Linking Killipia
with Sagraea and Mecranium in some trees on
the basis of the shared loss of strigose hairs (5)
probably has little phylogenetic significance.
The terminal-flowered taxa of Miconieae may
be a paraphyletic or monophyletic group basal to
all the axillary-flowered taxa (Fig. 2A-C) or a pos-
sible sister taxon to the taxa containing only druses
(Fig. 2D). In the first alternative, the axillary-
flowered condition evolved just once and serves as
a synapomorphy of all axillary-flowered Miconieae;
in the second, axillary arrangements are hypoth-
esized to have evolved in the druse and megastyloid
clades independently (or, less likely, evolved in the
stem lineage of the entire tribe with a reversal to
terminal cymes occurring in the ancestor of Mi-
conia and relatives). The possible polyphyly of the
axillary-flowered Miconieae clade will be investi-
gated more thoroughly in a later paper. It is cer-
tainly possible that Miconia and relatives are more
closely related to the axillary-flowered ““druse-con-
taining" genera than initially hypothesized.
When an EU representing a generalized ter-
minal-flowered taxon is included in the analysis,
the position of Huilaea in the cladograms becomes
more variable than in the initial analyses (compare
Figs. 1 and 2). This variability may reflect the
presumed phylogenetic isolation of this genus. It
seems more reasonable to link Huilaea with
Mecranium, Clidemia sect. Sagraea, Maieta, and
Killipia on the basis of the presence of only druse
crystals in its tissues (4) than with Loreya, Hen-
riettea, and Kirkbridea on the basis of a reversal
to pedicellate flowers (14) (Fig. 2).
he presence of both terminal and axillary flow-
ers in Clidemia sect. Miconiopsis (Cogniaux, 1888,
1891) is not surprising (see Judd, 1986a, for dis-
cussion of similar variation evident in Miconia,
especially in sects. Octomeris (Naudin) Benth. &
Hook. and Tamonea; and Troll, 1964, and We-
berling, 1965, 1988, for more general discussion
of inflorescence structure and position). Wurdack's
suggestion (pers. comm.) that this group is closest
to Miconia is likely correct. Note especially the
similarity in stellate indumentum (8; Fig. 4) and
circumscissilly dehiscent calyx (23). The section
may be quite close to Miconia sects. Tamonea and
Jucunda. The linking of Clidemia sect. Miconiop-
sis with. Killipia or a clade containing Killipia,
Clidemia sect. Sagraea, and Miconia in the cla-
distic analysis probably is due to homoplasy in
several fairly weak characters, e.g., loss of strigose
hairs (5), or to several potential synapomorphies
between the axillary-flowered taxa containing only
druse crystals and Miconia (and relatives), e.g.,
more or less sessile flowers (14) or well-developed
external calyx lobes (19).
In spite of the necessarily preliminary nature of
these cladistic analyses, their results help determine
the previously confused generic limits within this
difficult tribe (see also Judd, 1986a, b). In inter-
preting these results, I have attempted to delimit
monophyletic and phylogenetically equivalent gen-
era within the tribe that are recognizable on the
basis of several morphological characters. Thus
Huilaea, Mecranium (including Ekmaniocharis
and Ossaea acuminata), Killipia, Maieta (in-
cluding Clidemia sect. Calophysoides and C. ju-
ruensis), Loreya (including Bellucia and Myri-
aspora), Henriettea (including Henriettella and
Llewelynia), and Kirkbridea are considered to be
generically distinct. In addition, Clidemia sect.
Sagraea (including Necramium and the species of
Ossaea with axillary 4-merous flowers) is recog-
nized at the generic level. Finally, the species of
Ossaea with axillary 5- (or 6-)merous flowers are
in need of generic recognition and are described
herein as Pentossaea. The systematics of each of
these taxa is discussed briefly below.
Discussion of axillary-flowered genera.
Loreya is clearly delimited by its distinctive usually
robust fleshy anthers (34), expanded and radiately
ridged stigma (38), lack of external calyx lobes
(20), and range of chromosome numbers (42, see
Solt & Wurdack, 1980). The group possesses me-
gastyloids in its leaf and stem tissues (pers. obs.;
Baas, 1981) and is clearly monophyletic. However,
if Bellucia and Myriaspora are segregated as sep-
arate genera, the result is a paraphyletic Loreya
(Fig. 1). Bellucia is characterized by papillose
abaxial leaf cuticle (11), closed buds (24), i.e., the
buds have thick calyx lobes that cover the buds
up to the final stage prior to anthesis (and are even
fused into a cap in a few species, e.g., Bellucia
dichotoma Cogn. and B. acutata Pilger), and ten-
dency for floral merosities greater than five (16)
(see Renner, in press). In contrast, Myriaspora is
characterized by its highly divided placentae (39),
calyx lobes fused into an unusual cap (26, which
is probably not homologous with the cap of some
species of Bellucia), and long hairs on the abaxial

surface of its petals. In addition, Myriaspora pro-
duces inflorescences in the leaf axils (as do several
species of Bellucia), while the usual condition in
Loreya is to have the inflorescences lateral on
leafless nodes below the leaves; it should be noted,
however, that this character is often variable within
a genus (Judd, 1986a; Renner, in press).
No autapomorphies are evident for Loreya when
certain species are segregated as either Bellucia
or Myriaspora (Fig. 1). The paraphyly of Loreya
is made even more apparent when it is realized
that Loreya subrotundifolia (Wurdack) S. Renner
and L. riparia S. Renner link with Bellucia on
the basis of higher numbers of floral parts and that
L. mespiloides Miq., L. spruceana Benth. ex
Triana, and L. klugii S. Renner link with Myrias-
pora on the basis of testa characters and one-
pored anthers (Renner, in press).
hus, recognition of Bellucia and Myriaspora
distorts the best estimate of phylogenetic structure
currently available for this group of species. Their
recognition is also doubtful on purely phenetic
grounds, since the patristic distances separating
Bellucia and Myriaspora from the cladistically
related taxa within a narrowly delimited Loreya
are comparable to those separating other clades
within Loreya (Renner, in press). Thus, as is char-
acteristic of traditional taxonomic procedure (see
Stevens, 1984, 1986), recognition of Bellucia and
Myriaspora can only be justified by selective
weighting of certain features (in this case the char-
acters of cuticular papillae, bud structure, placental
form, and inflorescence position) due to their sup-
posed greater ecological significance. I see no rea-
son to weight these characters more than any oth-
ers used in these analyses. The decision to recognize
a broadly circumscribed Loreya is not new; Baillon
(1877) also considered Bellucia and Loreya con-
generic (although only few species were known to
him), and Macbride (1941: 497) considered this
. to 'straining at
treatment “‘preferable it seems . .
a gnat’ to keep them apart.” Gleason (1932) con-
sidered the genera only “weakly separated"; how-
ever, they were maintained as distinct by Wurdack
(1973, 1980) and Renner (in press).
Henriettea is easily recognized by its usually
expanded, radiate to globular-stellate basal portion
(or easily derived types, such as stellate-hairs, pel-
tate-scales, elongate hairs with numerous small
mainly basal projections, elongate hairs with a su-
prabasal expanded region and a narrowed basal
attachment, or hairs very reduced, e.g., Henriet-
tella caudata (DC.) Naudin, H. glabra Cogn.; see
Wurdack, 1986) (6), petals with a minute dorso-
apical apiculum (30), and chromosome number of
n — 28 (41, Solt € Wurdack, 1980). Fasciculate
inflorescences have evolved independently in a few
species of Loreya (Renner, in press), and the in-
florescences of Henriettea squamulosa (Cogn.) W.
Judd have reverted to a pedunculate condition (Judd,
1986b). Henriettea is clearly monophyletic and
shows the presence of calcium oxalate megastyloids
(similar in structure to those of Loreya) in its leaf
and stem tissues (pers. obs.; see also Welle &
Mennega, 1977; Welle & Koek-Noorman, 1981;
Baas, 1981).
As with Loreya, problems of paraphyly occur
when Llewelynia and Henriettella are recognized
as distinct from Henriettea (Fig. 1). Llewelynia
is phenetically distinctive (Pittier, 1939; Wurdack,
1973) and easily recognized by its loss of external
calyx lobes (20), open calyx cap that opens by a
circumscissile slit (27, 28), and numerous stamens
(37), while Henriettella is only marginally sepa-
rable due to its smaller flowers (17) and tendency
to have shorter anthers that open by larger, gaping
pores (see Wurdack, 1973, 1980). A nearly ob-
solete internal calyx has evolved in a few species
of Henriettella, e.g., H. sessilifolia (L.) Triana,
and in many species the internal calyx lobes are
not well developed. Henriettea and Henriettella
were considered congeneric by Macbride (1941:
500), who stated that "there seems to be no sig-
nificant concomitance of the characters of petals,
anthers or pubescence that have been used to main-
tain two similar but distinct genera.” He added
that “the characters moreover often exist in de-
grees of development.” Richard A. Howard also
will consider Henriettea and Henriettella to be
congeneric in his Lesser Antilles flora (pers. comm.).
Wurdack (1972: 418) maintained these genera
but noted that “a generic transition zone exists
between Henriettella ovata Cogn. and Henriettea
patrisiana DC., with Henriettella parviflora
(Griseb.) Triana perhaps not distinct from the lat-
ter.”
The genera differ in flower size, anther char-
acters, and indumentum, but intermediates exist.
Not surprisingly, there are no autapomorphies for
Henriettea when defined narrowly, and its species
certainly intergrade with Henriettella.
The floral buds of some other species of Hen-
riettea (e.g., H. spruceana Cogn., H. succosa
(Aublet) DC.. H. stellaris Berg ex Triana, and H.
ramiflora (Sw.) DC.) possess an expanded and open
cap formed by the inner calyx lobes very similar
to (and likely homologous with) that of Llewelynia,
although opening longitudinally rather than cir-

cumscissilly. These species are likely basal mem-
bers of the clade leading to Llewelynia. It is of
interest that Wurdack (1973) suggested a similar-
ity in general facies between Llewelynia and Hen-
riettella, and Welle & Koek-Noorman (1981) re-
ported similarity in wood anatomical characters
between Llewelynia and Henriettella. It thus seems
best to recognize a broadly defined, and monophy-
letic Henriettea by including both Henriettella and
Llewelynia within it.
Kirkbridea clearly is related closely to Hen-
riettea s.l. (Fig. 1). Kirkbridea (Wurdack, 1976)
is quite distinctive due to its pedunculate inflores-
cences and anthers with two well-developed dorso-
basal projections (33). Kirkbridea and Henriettea
show variation in number of floral parts.
Huilaea is evidently very isolated, as Wurdack
(1957, 1976) suggested at the time of his descrip-
tion of the genus. It clearly is distinct generically
and is recognizable due to its pendent, three-flow-
ered cymose inflorescences with very long pedun-
cles and large, clearly pedicellate, 6-merous flow-
ers.
Maieta, defined broadly, is a monophyletic group
best recognized by its characteristic pouchlike for-
micaria at the base of its leaf blades (10) (Fig. 3;
see discussion of morphology, development, and
ecological functions of these structures in Gleason,
1931; Schnell, 1967; Whiffin, 1972; Neto €
Asakawa, 1978; Benson, 1985). It should be noted
that ant-domatia of various types undoubtedly have
evolved independently in a few to many species of
several other genera (e.g., Sagraea DC., Tococa,
Clidemia, Henriettea, and Conostegia D. Don),
and additional developmental studies are necessary
in order to determine appropriate homologies of
such structures within the tribe. The presence of
structurally and positionally very similar pouchlike
ant-domatia is accepted as a provisional synapo-
morphy of Maieta s. od me Cudenia sect. t
ophysoides until s
are conducted. The group alo tends to Hadas e
ly wrinkled anthers (36) and clearly anisophyllous
leaves (9). Druses are the only crystals known in
this group. The species of Maieta (defined nar-
rowly—see Aublet, 1775; Wurdack, 1980) have
sagittate anthers (35) and show a reversal toward
large flowers (17), while those of Clidemia sect.
Calophysoides have a distinctly ribbed hypan-
thium (18). Both, along with possibly a few other
species of Clidemia, such as C. juruensis, are
considered congeneric. The close relationship be-
tween these species of Clidemia with pouchlike
formicaria and the phenetically similar species of
Maieta has long been recognized. Macbride (1941:
479) remarked that “Clidemia remains . . . a con-
cept rather arbitrarily retained but conveniently so
on account of Maieta (in which Baillon, Hist. Pl.
7: 56. 1880 rightly merged it) being the older
name." I agree and here consider Maieta to be
congeneric with Clidemia sect. Calophysoides (and
C. juruensis).
Killipia (Fig. 4) is a distinctive genus not easily
confused with any other in the complex of genera
possessing only druse crystals. Noteworthy apo-
morphies are the very long internal calyx lobes
with closely associated external calyx lobes (21)
and distinctive anthers with two dorso-basal pro-
jections (33); see description of genus in Gleason
(1925). The stems of Killipia quadrangularis are
quadrangular and ridged-winged (1); however, two
other species have terete stems. The abaxial leaf
surface of K. quadrangularis is usually red, an
apomorphy not included in the analysis, which has
also evolved within several genera with terminal
inflorescences. The cladistic relationships of Kil-
lipia are obscure, although it is closest to Maieta,
Mecranium, Sagraea, and Pentossaea (Fig. 1).
The species formerly of Ossaea with axillary
5-merous or occasionally 6-merous flowers warrant
generic recognition (Fig. 5). The petals of this
group are narrowly triangular with an acute apex
(29), and the group is clearly separable from related
taxa (see key). It is not surprising that a group of
Ossaea species was found to be in need of generic
recognition, since the genus has long been sus-
pected of being polyphyletic (see Judd, 1986a).
Wurdack (1962: 206), for example, stated that
"the genus is an artificial assemblage of various
species groups." The distinctive clade, with axillary
5-(6-)merous flowers, is here described as the genus
Pentossaea.

Additional new combinations will certainly be-

genus.
The axillary-flowered 4-merous species of Os-
saea and the very similar species traditionally placed
in Clidemia sect. Sagraea (also axillary-flowered
and 4-merous; see Cogniaux, 1891) are typically
separated by the technical character of apically
acute vs. blunt petals. However, I found this char-
acter to vary continuously within the group, and
several species placed in Clidemia sect. Sagraea
actually have acuminate or acute petals (e.g., C.
oligantha Urban, C. fuertesii Cogn., C. domin-
gensis (DC.) Cogn., C. crossosepala Griseb.), while
others treated in Ossaea may have blunt-tipped
petals (e.g., O. barahonensis Urban & E. Ekman
or O. setulosa Urban). Some taxa have been con-
sidered members of both groups by various authors.
In addition, phenetically very similar species have
sometimes been placed in the two "genera," e.g.,
Clidemia crossosepala and Ossaea hirtella (Sw.)
Triana (see Adams, 1972), and petal shape and
apex occasionally vary infraspecifically, as in Cli-
demia fuertesii. Thus, all 4-merous, axillary-flow-
ered members of the ““druse-containing group” (Fig.
2) with free internal calyx lobes, no androecial
fringe, and a usually well-developed strigose in-
dumentum are placed together in Sagraea (Fig.
6; also see key)
Necramium (Britton, 1924),
4-merous axillary flowers having ovate, sharply
acuminate petals and with an indumentum of long
strigose hairs and irregularly branched-stellate hairs,
clearly also belongs to this clade. A close association
between Necramium and some species of Ossaea
was recognized by Wurdack (1973: 721-722),
who stated that Necramium was "realmente bien
acomodado dentro de Ossaea DC. sensu Cogniaux
pero la necesidad por una transferencia posterior
a genus with
cuando ese conjunto artificial se disperse se opone
a la sinonimización inmediata." Wurdack (pers.
comm.) suggested affinity of Necramium to Ossaea
sect. Octopleura (Griseb.) Cogn. This is judged
unlikely, however, since the latter group has ter-
minal inflorescences (although frequently deflexed
to a seemingly lateral position, see Judd, 19864),
a glandular dorso-basal connective appendage, and
strongly costate fruits.
Necramium (Britton, 1924) is not the oldest
name available for this clade, the names Ossaea
and Sagraea (de Candolle, 1828) both having
priority. Because the types of Sagraea (S. cap-
illaris (Sw.) DC., here designated) and Ossaea (O.
scalpta (Vent.) DC., here designated) fall within
the group circumscribed above, and the two genera
were described at the same time (de Candolle,
1828), either name is available for this group. The
name Sagraea is chosen here, since I wish to avoid
the use of Ossaea, a name that has been used for
a great many discordant species-groups (see Wur-
dack, 1962, 1973, and Judd, 1986a). It is note-
worthy that Triana (1871) considered these axil-
lary-flowered species (along with a few discordant
elements) to be generically separable (as Sagraea)
from the terminal-flowered Clidemia.
Sagraea may be most closely related to Mecra-
nium, a more specialized genus also showing
4-merous flowers, this a potential synapomorphy
(15, Figs. 1, 2). Sagraea is considered to be meta-
phyletic (Donoghue, 1985; Mishler, 1985; Mishler
& Brandon, 1987) because its ca. 60 species show
no autapomorphies in some of the generated clado-

parallel evolution of 4-merous flowers (15). The
group is possibly paraphyletic, but no character
conclusively demonstrating this has been deter-
preferable to leaving its species in several artifi-
cially delimited genera.
Several species of Sagraea have evolved for-

has evolved in parallel in the two genera.

taining druse crystals by its internal calyx lobes
fused into a domelike, apiculate, and membranous
cap that is ruptured irregularly by elongation of
the style and emergence of the petals at anthesis
(22), the external calyx lobes reduced in length
and often inconspicuous (reversal of 19), androecial
fringe (i.e., a ring of erose to ciliate appendages
arising from apex of hypanthium [torus] internal
to the stamens [32 )), and usually sparse and poorly
developed indumentum (7); see Judd (19862) and
Skean & Judd (1986). Because these apomorphic
characters are found also in the monotypic Ek-
maniocharis (E. crassinervis; Urban, 1921; Judd,
1986a; Skean, in press), it is clear that this genus
belongs in Mecranium. Likewise, Ossaea acumi-
nata (Judd, 1986a) shows all these apomorphies
except that of a domelike, apiculate cap. In this
species the apices of the internal calyx lobes are
distinct and imbricate, although the lobes are con-
nate for most of their length, forming a structure
that may be similar to the condition from which
an apiculate cap was derived. It is obvious that O.
acuminata is a basal member of the Mecranium
clade. The nomenclatural transfers will be made
by James D. Skean, Jr. in a monographic study of
Mecranium currently near completion. A more
detailed analysis of the phylogeny of this genus will
be presented by Skean (in prep.)

taxonomic diversity) among the axillary-flowered

BIOLOGY IN NEOTROPICAL
MELASTOMATACEAE AND
MEMECYLACEAE!
ABSTRACT
In the Neotropics, the arena and de e comprise over 3,000 species in 106 genera. Pollination
observations have been reporte 26 species in 35 genera of Melastomataceae and for four species in one genus
of Memecylac ceae. Genetic llinc bo, has been found in 22 Melastomataceae species, self-compatibility in
25 species. A s ingle m e e tested i is self- -compatible. Agamospermy is known in 19 New World and
ace
is known in a few species in one genus of Melastomataceae. The principal mode of promoting outcrossing in both
families is spatial separation of pollen and stigma (herkogamy), achieved by the pollen being enclosed in poricidal
anthers, which have to be manipulated to release pollen. New World Memecylaceae are pollinated in the same way
and by some of the same bee species as most Melastomataceae. All bee species known to visit Melastomataceae and
Meise :ylaceae are list ed; they comprise a ius seda of the a bee fauna. It is not yet c wouie
in the ee mec ia beyond that ife en nhan cing the visual attractiveness of the eni and making ihe stamens
easier to grasp. In most Melastomataceae, flowers offer only pollen; however, some 60 species in 8 gene r
nectar as a reward for pollinators (probably, some species in at least one additional genus do, too). The nec dea
species are pollinated by birds, bats, rodents, and bees. e nectar is rich in sucrose and, as a rule, its production
is correlated with floral morphological changes relating to the fact that, except for bees, nectar consumers do not
vibrate the stamens to collect pollen actively. I suggest that the capacity for developing nectaries is ic in

lineages of Melastomataceae and emecylaceae, i a coevolved he earliest bees in the lo id-
Cretaceous. This may have been the time when the ancestors of these families switched from nectar-reward flowers
to pollen-r reward flowers. In the further extensive radiation of jm families, special adaptations to pollinators were of
limited importance; diversification in seed dispersal systems, vegetative characters, and edaphic adaptations were more
important.
The neotropical Melastomataceae and Meme- the field and the availability of several recent treat-
cylaceae are particularly suitable for a study of ments in monographs and floras. As Gleason (1932)

diverse in terms of habit, reproductive and vege-
tative architecture (Cremers, 1983), and indument
(Wurdack, 1986). Memecylaceae comprise about
89 species in the Neotropics and are much less
diverse in these characters.
The present survey is based on my observations
of the reproductive biology of many Brazilian and
some Venezuelan species and on a review of the
literature. The survey is presented in five sections.
First, an outline of the classification and repro-
ductive morphological features of the Melastoma-
taceae and Memecylaceae is given; second, breed-
ing systems and cytology are discussed; third, the
pollination spectra found in the two families are
described; fourth, a brief survey is made of seed
dispersal in the two families; fifth, the reproductive
biological information is related to the fossil record
and distributional data to contribute to a better
understanding of the historical evolution of the two
families.
Flowering and fruiting phenology of neotropical
melastomes and Memecylaceae are not dealt with
here, but reference ma made to Snow (1965),
Croat (1978), Opler et al. (1980), Hilty (1980),
Lumer (1982), and Renner (1984 and in prep.).
Suffice it to say that synchronous, episodic flow-
ering with the episodes of short duration (a few
days) characterizes some of the arborescent species
of the largest genus, Miconia, whereas extended
flowering periods (several weeks or months) are
characteristic of many of the shrubs, herbs, epi-
phytes, and some of the tree species.
CLASSIFICATION AND REPRODUCTIVE
MORPHOLOGICAL FEATURES
Worldwide, the Melastomataceae A. L. Juss.
(excluding the ca. ten species of Crypteronia, Ax-
inandra, and Dactylocladus, i.e., the Crypteronia-
ceae; Dahlgren & Thorne, 1984) and the Me-
mecylaceae DC. consist of ca. 190 genera and
approximately 4,800 species. In the Neotropics,
the Melastomataceae comprise over 3,000 species
in 107 genera (Table 1) and the Memecylaceae
89 species in two genera. About half of these genera
contain only one to four species, whereas one ge-
nus, Miconia, has some
lastomataceae as a subfamily, it has been pointed
out (see Morley, 1953; Dahlgren & Thorne, 1984;
Johnson & Briggs, 1984) that the differences be-
tween these families are such that their union ob-
scures rather than reflects our knowledge of the
two groups. The Memecylaceae consist of the Asian
genera Memecylon (ca. 300 spp.) and Lijndenia
(4 spp.) (Bremer, 1982, 1983), the African Spa-
thandra (6 spp.) and Warneckea (31 spp.), and
the neotropical Votomita (8 spp.; Morley, 1963)
and Mouriri (81 spp.). There is a consensus that
the Melastomataceae and Memecylaceae belong to
the core families of the order Myrtales (Dahlgren
& Thorne, 1984; Johnson & Briggs, 1984).
The classification of the Melastomataceae sensu
stricto is essentially that of Triana (1867), who
was closely followed by Cogniaux (1891). Wurdack
(1980) has realigned the New World tribes in a
sequence generally resembling that of A. P. de
Candolle (1828). The main dichotomy in the Me-
lastomataceae is between the capsular-fruited and
the berry-fruited genera. The genera are arranged
into tribes on the basis of fruit and seed characters
and the presence and position of connective ap-
pendages (D. Don, 1823; Triana, 1867; Cogniaux,
1891; Gleason, 1929; comp. also Whiffin & Tomb,
1972)
Most Melastomataceae are characterized by
poricidal anthers, the connectives of which are
frequently prolonged (however, species of Miconia
sects. Chaenopleura and Chaenanthera have an-
thers that open by 1-2 slits). They usually have
a pronounced foliar venation consisting of the mid-
vein and one to four pairs of subparallel longitudinal
veins. Memecylaceae, on the other hand, mostly
have pinnate venation; their anthers open by short
slits or pores. In a reproductive biological context,
the presence of an elliptic, concave gland on the
dorsal side of the connective is a unique feature
characterizing most Memecylaceae.

Renner 499
Reproductive Biology in Melastomataceae
& Memecylaceae
The flowers in both families are actinomorphic
or weakly to strongly zygomorphic as a result of
movements of the stamens and style immediately
after the expansion of the petals (Troll, 1922;
Ziegler, 1925; pers. obs.). In Melastomataceae,
the flowers are usually borne in well-developed
cymose inflorescences, whereas in Memecylaceae
the cymes are often condensed or reduced to a
few flowers in fasciculate tufts. In both families,
the mostly 4- or 5-merous flowers are perigynous
or epigynous with a cup-shaped hypanthium that
bears on its rim the calyx lobes, petals, and sta-
mens. The antepetalous stamens are usually longer
than the antesepalous ones, which may be stami-
nodial; this dimorphism is more or less pronounced
and has given occasion to much speculation con-
cerning its role in pollination. In Melastomataceae
with poricidal anthers, the anthers are one- or two-
pored, a character that is consistent at the species
level but varies within genera; there is also con-
siderable variation in the size and position of the
pores. Pollen grains are usually free, small, and
rather smooth, although polyads and tetrads are
known in species of Tococa and Miconia (Patel et
al., 1984).
BREEDING SYSTEMS
The principal mode of promoting outcrossing in
most Melastomataceae and Memecylaceae is the
very effective spatial separation of pollen and stig-
ma in the flowers (herkogamy). This is achieved
by the pollen being enclosed in tubular anthers with
apical or subapical pores or slits, which are gen-
erally minute, and positioned well distant from the
punctiform or capitate stigmas. Also, the stamens
are usually shorter than the styles. In bud, the
stamens are always folded over in such a way that
the anther pores point downward and are maxi-
mally distant from the stigma, which lies at the tip
of the bud. Thus, chances for automatic selfing
before and during anthesis are very low or nil. If,
however, during anthesis, an anther or the style
bends in such a way that the pore is brought into
contact with the stigma, automatic selfing may
occur. This has been reported for Monolena
trichopoda (Melastomataceae; Warner, 1981)
where, late in anthesis, the stamens fold over and
the thecae are effectively stuck to the stigmatic
exudate.
No pollen escapes from the anthers unless me-
diated by a vector, which at least potentially may
arrive bearing conspecific pollen. Almeda (1977,
1978) suggested that vigorous mechanical move-
ment of the anthers by gusty winds or rains might
release pollen in species of Monochaetum and Cen-
tradenia (Melastomataceae). Additionally, he often
observed pollen in water droplets connecting an-
thers and stigma and suggested that this might be
another possible route for selfing to occur. How-
ever, bees, which regularly collect pollen from Me-
lastomataceae, use vibrations of around 420 Hz or
higher (this frequency was found to effect ample
pollen emission from the large anthers of Bellucia;
see below). Therefore, it seems unlikely that the
low-frequency vibrations produced by wind could
release pollen This
impression is supported by the lack of fruit set in
bagged flowers of nonagamospermic species ex-
posed to strong wind (Renner, 1984). While autog-
amy may be extremely rare, vector-mediated self-
ing (i.e., geitonogamy), a function of pollinator
behavior and number of conspecific flowers avail-
able at a time, may be frequent in self-compatible
rom melastome anthers.
species.
Temporal separation of male and female func-
tion has been suggested for species of Monochae-
tum (Almeda, 1978) in which *'the ill-defined stig-
matic region . . . appears to be non-receptive during
the first day." This may be a rare condition be-
cause, as a rule, poricidal flowers that offer only
pollen as a reward (subsequently also called “‘pol-
len-only flowers”) receive foreign pollen at the same
time a visitor harvests pollen from them; in female-
phase flowers, there is nothing to reward visitors
(only mimicry or deception might account for visits
to female-phase flowers). Homogamy, i.e., the si-
multaneous functioning of the male and female
parts, is thus to be expected in pollen-only flowers.
Temporal separation of the male and female func-
tion in single flowers has been reported twice in
nectariferous melastomes (Ule, 1896; Vogel, 1957);
in both cases, the flowers were protandrous.
The Melastomataceae are not entirely her-
maphroditic. Wurdack (1964) was the first to de-
scribe dioecism in Miconia dioica Wurdack; her-
barium specimens of this species had female flowers
with abortive stamens and male flowers with poorly
developed stigmas. He also suspected dioecism in
some other minute-flowered Andean species of Mi-
conia (M. dielsii Markgraf, M. clathrantha Tr.
ex Cogn., M. minuta Gleason; Wurdack, 1980:
261-262) and in M. rubens (Sw.) Naudin from
the West Indies and Venezuela (Wurdack, 1964).
Field observations on the reproductive biology of
these and some other suspected dioecious mela-
stomes are lacking.
At least one species of Lijndenia (Memecyla-
500
Annals of the
Missouri Botanical Garden
ceae) has hermaphrodite-flowered individuals and
purely male-flowered ones (Bremen, 1982).
GENETIC COMPATIBILITY
As shown in Table Z, genetic self-incompatibility
occurs in at least 22 species in the two families.
As Darwin remarked (in a letter to J. D. Hooker
on Nov. 28, 1871, in F. Darwin (ed.), 1903),
melastomes *'are troublesome beasts to fertilise.”
This is due to the closed anthers and mostly punc-
tiform stigmas. In some large-flowered species, such
as Bellucia (Melastomataceae), it is possible to
collect large amounts of pollen for experimental
purposes by holding a tuning fork to the stamens.
Self-compatibility is found in 26 species (Table 2).
Since no efforts have ever been made to distinguish
pseudogamy from self-compatibility, several of the
supposedly self-compatible species reported earlier
(Darwin, 1876; Ziegler, 1925) may have set fruit
as a result of agamospermy rather than of self-
fertilization. Related species such as Tococa guia-
nensis and T. bullifera or Centradenia grandi-
flora and C. paradoxa (all Melastomataceae) differ
O
in their compatibility conditions (Table 2). Th
humid stigmatic surface and the binucleate pollen
of the Melastomataceae and Memecylaceae (Tobe
& Raven, 1984) indicate that the incompatibility
system is gametophytic (Nettancourt, 1977)
AGAMOSPERM Y
Experimental proof of agamospermy in mela-
stomes is readily obtained by cutting off the style
in freshly opened unvisited flowers. (To ensure that
flowers are unvisited before the style is cut off,
they must be bagged the evening before.) Apart
from the 22 apomictic Melastomataceae listed in
able 3, polyembryony, with additional embryos
baina formed by nucellus or suspensor cells, has
been reported from the Asiatic species Osbeckia
hispidissima Wight, Sonerila wallichii Benn., and
Melastoma malabathricum L. (Subramanyam,
1942, 1944, 1948). Polyembryony is often cor-
related with agamospermy (Gustafsson, 1946-47).
Mouriri nervosa is the only member of the Me-
mecylaceae so far tested for agamospermy, with
negative results (Renner, unpubl.). In several of
the neotropical species showing apomixis, for in-
stance in Clidemia novemnervia and Macairea
theresiae, the anthers contain very few pollen
grains. In cultivated neotropical Leandra cordi-
folia Cogn., Subramanyam (1942) also found that
a low percentage of fertile pollen grains was com-
bined with the frequent formation of two embryo
sacs. In most neotropical species, agamospermy is
correlated with low stainability of fresh pollen in
cotton blue with lactophenol. This stain indicates
presence of callose, a saccharide found in the intine
of pollen. Lack of an intine could make a grain
unviable and is usually accompanied by lack of
cytoplasm. However, in Aciotis acuminifolia and
Miconia argyrophylla, pollen grains stain heavily,
yet these species are capable of producing seeds
apomictically. In Clidemia and
Maieta poeppigii, the stamens do not unflex com-
novemnervia
pletely upon anthesis but remain curved, and are
thus not available for legitimate bee pollinators.
Both species regularly set seeds apomictically.
82) observed that Blakea gracilis,
Blakea sp. (originally identified as B. grandiflora),
and Topobea brenesii ripened a large number of
seedless fruits from emasculated flowers; however,
in T. pittieri, she found that of the bagged flowers,
35% produced mature fruits containing seeds. Dar-
win (1876) and Ziegler (1925) observed fruit set
in cultivated plants of Monochaetum, Tibouchina,
Centradenia, Calvoa, and Dissotis in the green-
house. Assuming that there were no bee pollinators
Lumer
in the greenhouses, it is likely that such fruits
resulted from agamospermy rather than from
autogamy, which, as pointed out above, is me-
chanically difficult in Melastomataceae.
The number of species investigated is still too
small to draw firm conclusions about correlations
between habit, habitat, and breeding system. Of
the agamospermous species, 13 are shrubs of var-
ious types of savannas or of secondary vegetation;
five are treelets, two are herbs, and one is a climber.
The sample is clearly biased towards shrubby
species, however, because of their accessibility.
CYTOLOGY
Some 300 of the over 3,000 species of neo-
tropical Melastomataceae and only one species of
Memecylaceae (Mouriri myrtilloides) are known
cytologically (Solt & Wurdack, 1980). Only a few
of these have been examined twice. Melastome
chromosomes are very small (0.5-1 micron; Solt
S Wurdack, 1980) and stain poorly.
common base numbers are 9 and 17 (Wurdack &
Kral, 1982). Based on Solt & Wurdack's results,
the incidence of polyploidy in the Melastomataceae
The most
seems high. It cannot yet be answered whether
polyploidy is more frequent in species with strong
agamospermous reproduction than in those which
lack apomixis, nor whether there is a correlation
between polyploidy and growth habit.

and rodents is found in an estimated 60 species of
Meriania, Centronia, Brachyotum, Tibouchina,
Miconia, Huilaea, Chalybea, and Blakea (Table
4), and probably also in Axinaea (see below). The
mode of pollination is determined by the type of
reward offered: Melastomataceae and Memec yla-
ceae with pollen-only flowers are, as a rule, polli-
nated exclusively by bees because the morphology
of the anthers excludes all other pollen-collecting
vectors. In contrast, the nectar-offering species
attract a wide variety of pollinators.
a) Methods of pollen collection and kinds of bees
Pollination by bees has been reported for some
120 species in 31 genera of Melastomataceae (Ta-
ble 4). In addition, a few species occurring at Finca
La Selva, Costa Rica, and near Kourou, French
Guiana, have been observed to be pollinated by
small and medium-sized bees (Bawa et al. 1985;
Roubik, 19792). Many unidentified melastomes are
indicated as visited by bees in apidological studies
(e.g., Sakagami et al., 1965, and Roubik, 1979b).

Annals of the
Missouri Botanical Garden
Bees gathering pollen from Melastomataceae flow-
ers must be able to shake it out of the anthers or
else pull pollen grains out through the pores with
their tongues. This latter mode of exploiting mela-
stome flowers is used by a group of Trigona bees
and does not usually result in pollination because
these bees are too small to contact the stigmas.
Another subgroup of Trigona bees, characterized
by having toothed mandibles, cuts up melastome
anthers and robs their pollen (Laroca, 1970;
ner, .
The method of pollen collecting used by all other
bees to extract pollen from melastome anthers was
first described correctly by van der Pijl (1954).
When approaching a flower, in flight, the bees
orient themselves with the group of stamens and
the style and then straddle the stamens. They usu-
ally grasp the filaments or the bases of the anthers,
quite often using their mandibles. Therefore, after
having been visited, flowers often show necrotic
spots on the outside of the stamens where the bees
held onto them. When the bees position themselves
over the androecium, their potentially pollen-bear-
ing surface contacts the stigma even before they
start exploiting the anthers. Also, they strive to
establish a firm contact with as many stamens as
fT,
their body size permits, going tc
in order to bundle all 8, 10, or 12 stamens. Close
contact between the bee and the stamens is nec-
essary for pollen collection by means of thorax
vibrations, which are transmitted to the stamens
and cause the pollen to stream out of the anther
pores. Electrostatic forces due to the net positive
charge of the bees and the negative charge of pollen
greatly aid pollen-load adhesion (Thorp, 1979).
When a pollen load, taken with forceps from a
freshly captured bee, is released near this bee, it
jumps back onto it (pers. obs.). The very rapid
distortions of the thorax-box (with the wings at rest)
are made possible by the unique contractile prop-
erties of the bees’ fibrillar indirect flight muscles.
Pollen collecting by this method is always accom-
panied by a characteristic buzzing sound and has
Michener, 1962).
The rapid vibrations used when harvesting mel-
astome pollen presumably produce a high temper-
ature of the flight muscles,
this method of pollen collecting is particularly ap-
been termed “‘buzzing method” (van der Pijl, 1954;
)
which may mean that
propriate during the relatively cool early morning
hours. Also, there are ecological constraints on the
activity of dark-colored bees during the hottest
hours. Buzz pollination continues with very high
humidity of the air and even during slight rains.
In most melastomes, pollen deposition and re-
ception is on the lower abdomen (sternotribic) or
lateral on the bees (pleurotribic); it is on the back
(nototribic) in a few species with downwards-curved
styles (e.g., species of Meriania, Adelobotrys, Sal-
pinga) and in Desmoscelis villosa. In these cases,
bees assume quite unexpected positions in order to
vibrate the stamens; in Adelobotrys rachidotricha,
for instance, they buzz with the head pointing out-
ward and downward. Relatively large flowers, such
as those of Blakea, Topobea, and Bellucia, are
by a ua range of bees (Lumer, 1982;
Renner, 1986/1 87). For example, stamens of
Bellucia are us by 33-mm-long Centris and
8-mm-long Augochloropsis bees. In the case of
self-compatible species, visits by bees too small to
contact the stigma and deposit foreign pollen may
still result in self-pollen landing on the stigma when
such small bees vibrate one or a few stamens.
Bees visiting Melastomataceae exhibit consid-
erable steadiness during individual foraging flights:
pollen loads often consist of almost pure melastome
pollen with very few grains from nectariferous flow-
ers or with grains from Cassia mixed in (Renner,
984). Cassia has buzz-pollinated flowers, and bees
often visit several such flowers (see below).
In Brazilian Amazonia, | have captured 80
species of bees, including the Africanized honey
bee, Apis mellifera scutellata Lepeletier, vibrating
melastomes. (A list of all bees, including the species
of Trigona, may be obtained upon request.) Ad-
ditional species have been captured in extra-Am-
azonian areas and at higher altitudes. To date, at
least 100 species of bees have been found polli-
nating melastome flowers (Table 4; this does not
include the numerous species of pollen-scavenging
Trigona bees). The relatively few groups of bees
that have been successful in tropical forest envi-
ronments, the euglossines, halictids, Xylocopa, and
Melipona (Michener, 1979)
tant pollinators of lowland melastomes. In savan-
are the most impor-
nas, Centridini, Oxaeidae, Exomalopsini, and Ptilo-
a
o
glossa (Colletidae) become important, as
bumblebees in southern Brazil and at higher alti-
tudes. The bee fauna in neotropical forests and
savannas is still incompletely known; however, based
on bee inventories in Panama, Costa Rica, French
Guiana, Surinam, and at the mouth of the Amazon
(Heithaus, 1979; Roubik, 1979a, b; and ref. in
Michener, 1979), it may be estimated that only
about 300 species of bees occur in these forests,
a number that includes non-flower-visiting parasitic
and leaf-cutter bees. Thus, between 80 and 100
species collecting pollen from Melastomataceae
represents a high proportion of the total Amazonian
bee fauna

b) Floral attractants
Melastome pollen is an important pollen source
for neotropical bees. This is clear from a survey
of literature on bee foraging: it is collected by
female euglossines (Moure, 1970; Janzen, 1971;
Michener et al., 1978; Roubik, 1979a, b; Dressler,
1982; Renner, 1984), meliponines and halictids
(Ducke, 1901, 1902; Laroca, 1970; Roubik,
1979a, b; Michener et al., 1978; Absy & Kerr,
1977; Absy et al., 1980), mixed with Malpighi-
aceae oil by anthophorine bees (Vogel, 1974; Ren-
ner, 1984), and makes up 96-100% of the nest
provision of the colletid bee Crawfordapis (Roubik
& Michener, 1985). A chemical analysis of Bel-
lucia dichotoma pollen revealed high nitrogen and
total crude protein. (I am indebted to S. Buchmann
for analyzing a pollen sample in 1983.) In this
species, the pollen has a strong perfume resembling
that of the flowers.
Secondary attractants for bees include sweet or
perfumelike floral odors produced by the petals,
the connective, and the upper section of the style
(as determined by neutral red staining; pers. obs.;
method, Vogel, 1963), and the presence of a land-
ing platform provided by the androecium. I have
never seen bees land on the petals. Frequently, the
filaments are adorned with glandular or eglandular
hairs, which may make them easier for the bees
to grasp. Also, direct alighting on the stamens may
make visits to flowers with poricidal anthers par-
ticularly rewarding compared with flowers requir-
ing further crawling and searching after landing.
Most Melastomataceae seem to be visited and
pollinated early in the morning, sometimes 20 min-
utes before sunrise (F. Mueller, 1873; Frankie,
1976; Lumer, 1982; Renner, 1984), and many
species close their petals by late morning. However,
flowers of Monochaetum and Rhynchanthera open
late, two to four hours after sunrise (Almeda, 1978;
pers. obs.). Shedding of the flower parts usually
starts at the end of the second day. Again, Mono-
chaetum differs in having flowers that stay open
for three days (Almeda, 1978), and I have seen
Graffenrieda fruticosa flowers staying attractive
for at least seven days. In the latter case, the
adverse climatic conditions at 2,200 m altitude,
where Graffenrieda fruticosa occurs, may place a
high selective advantage on longer flowering pe-
riods which presumably heighten the flowers'
chances of being visited.
The typical bee colors of most Melastomataceae
flowers, white, purple, or pink, are due to total
reflection and anthocyanins (Lowry, 1976; Bobbio
et al., 1985). Yellow and orange flowers evolved
repeatedly in isolated species throughout the fam-
ily. Contrasting marks at the base of the petals and
color changes during anthesis are frequent in
Melastomataceae (F. Mueller, 1873; Ule, 1896;
Wurdack, 1980; Renner, 1984). The colors change
from white to red, from yellow to red, from white
to purple, or from pink to white. The bright white
of the small flowers of many herbaceous understory
melastomes, e.g., species of Aciotis, Leandra, Cli-
demia, Miconia, and Ossaea, may be of selective
advantage under conditions of low light intensity.
Some melastome flowers tested (using a Kodak 18
Wratten filter) did not absorb ultraviolet light (Lu-
mer, 1982), as was to be expected from the absence
of flavonols from their petals.
The androecia of many species in the capsular-
fruited tribes Merianieae, Bertolonieae, Micro-
licieae, Tibouchineae, and Rhexieae show a strong
morphological differentiation into two sets of sta-
mens. In addition, in such flowers the connective
appendages may be large and stiff, forming 5, 10,
or 15 usually yellow spurs, sometimes positioned
like true anthers. Based on his brother's (Fritz
Mueller) observations on a southern Brazilian species
of ** Heeria," Hermann Mueller (1881, 1883) was
the first to suggest that this dimorphism was the
ultimate result of a **division of labor" between the
two sets of stamens (his illustration shows that his
brother was probably dealing with a species of
Microlicia; Heeria is synonymous with Hetero-
centron, which does not occur in southern Brazil).
According to this idea, the conspicuous anthers
attract the bees and offer “food pollen” as a re-
ward, whereas the less conspicuous ones contain
“functional pollen." The “functional pollen" is sup-
posed to be placed on a part of the bee where it
will not be groomed off and used as food for larvae.
It will instead function in fertilization. Hermann
Mueller’s idea caught on immediately (Forbes,
1882; F. Mueller, 1883) and is usually mentioned
as typical of the pollination strategy of Melasto-
mataceae (e.g., Cammerloher, 1931; Percival,
1965; Kugler, 1970; Proctor & Yeo, 1972; Ba-
ker, 1978; Faegri & van der Pijl, 1979).
A partitioning of the bee surface would be nec-
essary for selection to favor the pollen grains from
one set of stamens over those from the other and
thus lead to pollen dimorphism. Pollination mech-
anisms involving vibration of anthers, however,
may not allow a sufficiently precise placement of
pollen from two sets of stamens on bees. Forbes
(1882), working with unnamed species of Mela-
stoma, reported that “only the pollen from the long
stamens seemed [sic] to be fertile"; yet he found
pollen from both types of stamens on the stigmas.
To date, with the exception of Forbes's report
510
Annals of the
Missouri Botanical Garden
(1882), no morphological or physiological differ-
ences between pollen grains from dimorphic sta-
mens have been found in any of the Melastoma-
taceae studied (Darwin, 1876; Ziegler, 1925;
Whiffin, 1973; Almeda, 1977; Renner, 1984).
Further experimental fieldwork is needed to assess
whether the staminal dimorphism and the stamen
appendages have a function beyond that of en-
hancing the visual attractiveness of the flowers and
making the stamens easier to grasp for bees. In
view of the importance of pollen aromas for guiding
bee behavior (cf. Dobson, 1987), it is uncertain if
the visual cues provided by the yellow connective
appendages by themselves elicit pollen-collecting
behavior
POLLINATION OF NECTAR-PRODUCING MELASTOMATACEAE
BY BIRDS, BATS, RODENTS, AND BEES
Some 60 species of Meriania, Centronia,
Brachyotum, Tibouchina, Miconia, Huilaea,
Chalybea, and Blakea, all of them, except the
species of Miconia, occurring at higher altitudes
(1,600-3,400 m), offer nectar as a reward for
their pollinators. On the basis of their character
syndrome (see below), Meriania drakei (Cogn.)
Wurd., M. furvanthera Wurd.,
and several other species of Meri-
Centronia, and Tibouchina are

he first reports on nectar production in mel-
astomes are by Ule (1895, 1896). In three species
of Tibouchina (Table 4) growing on the Brazilian
Itatiaia mountain range, he observed that nectar
was produced by the staminal vascular bundle and
secreted either directly from the filaments or some-
times through a slit in the filaments. He suggested
bumblebees as the probable pollinators of these
species. At Ule's request, the chemist T. Peckolt
analyzed the stamens of another species that did
not secrete nectar (Ule gave the name as 7. glare-
osa Cogn.; there is no such name, and he probably
meant 7° granulosa Cogn.). Peckolt found that
ugar was present “in great quantity," which sug-
eed to Ule (1896) that this was likely true for
other species of Tibouchina as well. In several
Pry
other nectariferous melastomes, slits in the upper
ventral side of the filaments have been observed,
e.g., in Tibouchina cleistoflora Ule (Ule, 1896;
pers. obs.), T. grossa, Blakea chlorantha (Tobe
et al., in prep.), Brachyotum ledifolium, B. an-
dreanum Cogn., B. benthamianum Triana, and
B. rugosum Wurd. (Lagerheim, 1899; pers. obs.).
They have also been found in non-aectariferous
species— such as Centradenia grandiflora, Het-
erocentrum roseum, Triolena pustulata (as Ber-
tolonia pubescens) —and in paleotropical species
of Dissotis and Medinilla (Ziegler, 1925). These
slits appear not to be consistently formed sutures,
but rather spontaneous ruptures. The anatomy of
the nectariferous tissue is being studied by Tobe
et al. (in prep.).
eports of nectar in Miconia minutiflora (Mori
& Pipoly, 1984) are unclear, since its presence in
the minute flowers (2.5 mm in diameter, style 4
mm long) was only presumed. In central Amazonia,
where I have observed this species, it did not pro-
duce nectar (Renner, 1984). However, in another
Miconia species in the Belém region at the mouth
of the Amazon, Roubik measured floral nectar of
ca. 20% mgar tad and collected Meli-
, pers. comm. 198
Recently, nectar N has also been con-
firmed in the Antillean endemics Miconia sintenisii
Cogn. and Mecranium amygdalinum (Desr.)
/right (Dent, pers. comm.). Miconia robinson-
iana, also with minute white flowers, was included
under "nectar sources"
records for Xylocopa darwinii by Linsley et al.
1966). McMullen, who made further observations
on the floral visits of this bee on Galápagos
(McMullen, 1985), has never noticed any nectar
in M. comm.,
1987)
Except in Miconia, nectar production in Me-
lastomataceae is correlated with floral morpholog-
ical changes that relate to the fact that the nectar

when nectar instead of pollen is the pollinator re-
ward, the latter must be deposited on a visitor
during nectar uptake. This is achieved by the an-
thers having rather large pores and being stiffened,
particularly at the base. Pressure on the base of

The bulk of nectariferous melastomes seem
hummingbird-pollinated (Table 4). Most of them
belong to the genus Brachyotum, which comprises
50 species, the majority ornithophilous (Wurdack,
1965, 1980; Lagerheim, 1899; Vogel, 1957; Fitz-
patrick et al., 1979; label data). Other bird-polli-
nated species are Meriania tomentosa (Cogn.)

Werff, pers. comm.; D. Nei
tariferous and hummingbird-pollinated species in
the Miconieae are Huilea macrocarpa, H. pen-
duliflora (Snow & Snow, 1980) and probably also
Chalybea corymbifera (in which Stein observed
nectar but no pollination events; pers. comm.,
1987). The Colombian Tibouchina grossa is pol-
linated by bats and hummingbirds (Vogel, 1957;
Stein, pers. comm., 1987) and certainly the same
is true of T. Stricta Wurd. and T. reticulata Cogn.
New World rats and mice of the tribes Pero-
mycini and Oryzomini pollinate at least three nec-
tariferous species of Blakea in Costa Rica (Lumer,
1980, 1982; Lumer & Schoer, 1986). Lumer
found that bees and hummingbirds rarely visited
the flowers of these species during the day but that
nectar secretion was nocturnal. The Blakea species
involved are hemiepiphytic, and their flowers are
positioned close to the stem where the rodents can
reach them conveniently.
The nectar of Blakea chlorantha contains ca.
1195 sucrose (Lumer, 1982, and pers. comm.);
that of Huilea macrocarpa has 12-16% with a
mean of 13.495 (Snow & Snow, 1980); that of
Chalybea corymbifera 16.5%; and that of
Brachyotum ledifolium 20-22% (Tobe et al., in
prep.). It would thus be classified as relatively rich
in sucrose in the nectar class system of Baker &
Baker (1983), who found that sucrose-rich or su-
crose-dominated nectar prevails in hummingbird
flowers. Thus, nectariferous melastomes offer a
reward “intended” for pollinators other than bees.
The evolutionary origin of pollination systems
involving nectar in Melastomataceae is considered
below
ll, pers. comm.). N
MEMECYLACEAE
In their pollination mechanism, the neotropical
Memecylaceae closely resemble the Melastoma-
taceae, and the above description of bees’ methods
of pollen collecting from melastome flowers also
applies to them. In Mouriri, the anthers are stiff,
with thickened endothecial walls, and are slightly
prolonged just above the insertion of the filaments.
The prolongations, termed "caudae" (Morley,
1953), are used as footholds by the bees exploiting
Mouriri anthers. Pollination in four species of Mou-
riri has been observed (Table 4); the main polli-
nators seem to be euglossines, followed by Xyloco-
pa and Melipona species. They are legitimate
visitors, i.e., large enough to contact the stigma
regularly while collecting the reward. Memecyla-
ceae anthers differ from those of Melastomataceae
in bearing dorsal concave glands, 0.3-0.8 mm
long. (For illustrations of the permutations in size
and position of these glands in Mouriri and Vo-
tomita, see Morley, 1953, 1976, and 1985.) None
of the legitimate pollinators show any interest in
the staminal glands (Buchmann & Buchmann,
1981; Renner, 1984, and unpubl.).
Earlier (1984), I reported that Melipona mar-
ginata and M. fulva sometimes collected the se-
cretion from the glands with the front legs, and
that they mixed this substance with their pollen
loads between pollen-collecting bouts on the wing.
Further field observations, however, have con-
vinced me that Melipona does not regularly touch
the glandular surface when buzzing. The bees grip
the stamens by the anther caudas just below the
glands, and it is difficult to see what they do with
their feet or their mouth parts when vibrating be-
cause they curve tightly over the anthers to allow
the pollen stream to settle on their bodies. Between
buzzing bouts, Melipona bees (and the euglossines)
rotate over the androecium so as to drum out the
pollen from all ten anthers. Staining of their freshly
collected corbicular loads with Fehling solution
showed that the pollen had been wetted with sugar.
With Sudan III (a lipid stain), Mouriri pollen grains
stained red, but the secretion holding them together
did not; this implies that the pollen contains lipids,
whereas the secretion did not.
Mouriri flowers are also visited by several species
of Trigona. These small bees do not regularly con-
tact the stigma but rob pollen from the anthers,
which they are unable to buzz. Their role as pollen
scavengers and robbers in Melastomataceae is well
known (Renner, 1983). When cutting up anthers
of Mouriri nervosa to reach pollen grains further
down, Trigona williana very rarely touched the
glands (Renner, 1984, and unpubl.). Most often,
T. williana cut off the anthers above the glands,
then stopped and started cutting and robbing the
pollen of another anther. This shows that this pollen
robber, like the legitimate pollinators, does not reg-
ularly collect the glandular exudates. Buchmann
& Buchmann (1981) have observed T. pallens
manipulating the glands of M. myrtilloides with
the front legs and mouth parts.
The secretion of the staminal glands is yellow,
viscous, stains red in Sudan III, and tests positive

for fatty substances. That of the relatively large
(0.8 mm long) glands of M. lunatanthera forms
myelin figures in water after a drop of sodium
hydroxide is added (pers. obs.; method from Vogel,
1974). The secretion in M. myrtilloides has been
reported to be a lipoidal mixture of many com-
pounds (e.g., phenolic Rud. small amounts
3 fatty acids, and
free fatty acids) and to be * een rich in non-
(Buchmann & Buchmann,
of glucose and saponin, at least
lipid constituents"
1981)
Since the secretions from the floral glands con-
tain lipids, the relationship between Mouriri and
oil-collecting bees is of particular interest. Floral
oils are collected by bees belonging to relatively
few genera of Anthophoridae (e.g., Centris, Epi-
charis, Monoeca, Paratetrapedia, Tapinotaspis,
Tetrapedia; cf. Vogel, 1974; Ne Simpson,
1981). Although many of these collect pollen from
Melastomataceae (comp. Table 4), to date only a
single anthophorid bee species, Paratetrapedia
calcarata, has been observed on Mouriri (Buch-
mann & Buchmann, 1981). This bee, due to its
small size (7-8 mm long), rarely vibrated more
than two or three of the ten anthers in each flower
and only rarely touched the stigma (l.c.). Also,
Buchmann € Buchmann (1981) reported that
Paratetrapedia calcarata was an infrequent vis-
itor of M. myrtilloides (16 times during 50 hours)
and not a legitimate pollinator.
The secretion of the staminal glands forms a
shiny film on the gland cuticle and in this respect
differs greatly from the lipid-filled blisters of other
epithelial elaiophores (Vogel, 1974). Paratetra-
pedia has scrapers on the fore-basitarsi (Neff &
Simpson, 1981) and ruptures the cuticle of the
elaiophores from which it collects oils. While scru-
tinizing hundreds of stamens from Mouriri nervosa
and M. guianensis under the stereoscope in order
to collect their glandular secretions, I never found
signs of the glands having been scraped. This was
perhaps to be expected, since the secretion forms
a film on the outside of the cuticle.
A further problem in understanding the role of
the staminal glands is that they are so small and
positioned in such a way that the collection of any
exudate either with the fore-basitarsi or the mouth
parts by the medium-sized bees that pollinate Mou-
riri is difficult to envisage. Visitors small enough
to be attracted by the minute quantities of secretion
offered (such as the Paratetrapedia species ob-
served by Buchmann & Buchmann, 1981) are not
large enough to touch the stigmatic surface when
manipulating the glands, especially since the styles
in Mouriri are always longer than the stamens and
the stigmas are held well away from the anthers.
A possible role of the staminal glands suggested
by Morley (1976) is odor production. Mouriri
species often have a strong perfume scent (Buch-
mann & Buchmann, 1981; Renner, 1984). Per-
haps a volatile oil would persist longer when mixed
with the fatty oils and other compounds. Buchmann
& Buchmann (l.c.) suggested that the glands, which
absorb ultraviolet light, might visually guide the
bees to the pollen. Extending this idea, one might
ascribe a pseudonectary role to the staminal glands.
It is interesting that in the Bonnetiaceae, at least
23 species of Caraipa and Mahurea have very
similar minute urceolate glands positioned subapi-
cally on the connective (Kubitzki, 1978). The role
of these glands, as of those of Mouriri, is obscure.
SEED DisPERSAL IN MELASTOMATACEAE
Of the neotropical Melastomataceae, 40% have
capsular fruits and wind-dispersed seeds (Renner,
1986). The remaining 60% have soft, juicy berries
and endozoochorous seeds. Animal-dispersed Me-
lastomataceae are most diverse in lowlands and
montane forests, whereas the capsular-fruited tribes
are richest in species in various types of savannas.
Melastome capsules are often sturdy and persist
on the plants for many months, during which the
seeds are gradually shaken out. There are no data
on dispersal distances in the wind-dispersed species;
however, the many striking disjunctions observed
1987b,
press) probably attest to their good dispersability.
in savanna melastomes (Renner, and in
Small herbaceous understory species with broadly
conical capsules ee O Bertolo-
nia) may also have thei
by raindrops.
Melastome berries range in size from five to ca.
d ballistically
35 mm in diameter. The smaller ones are of out-
standing importance for small frugivorous birds
throughout the Neotropics (Huber, 1910; Snow,
1965, 1971, 1981; Ricklefs, 1977; Skutch, 1980;
Lumer, 1982; Wheelwright et al., 1984; R. Bier-
regård, pers. comm., and many additional refer-
ences). Epiphytic Melastomataceae are mostly bird-
dispersed (Renner, 1986), as are many of the most
successful pioneer species, for example, Clidemia
hirta, which has become a noxious weed in Africa,
Asia, and Hawaii.
Fruit attributes, such as position, size, aroma,
and color, indicate that different animal classes act
as the principal dispersers in different species groups.
For example, black spider monkeys are the pre-
dominant consumers and likely dispersers of the
green, slightly astringent and relatively large ber-
ries of the tree Bellucia grossularioides in Suri-
nam (Roosmalen, pers. comm. ). In French Guiana,

this species is a favorite with the PAilander opos-
sum (Atramentowicz, 1982), which also eats Hen-
riettea and Loreya fruits. However, a search of
recent literature on feeding records (Renner, 19872)
showed that Melastomataceae are not among the
preferred foods of either monkeys or bats (for bats,
Fleming, 1986; but compare Foresta et al., 1984,
and Fleming, 1988). Perhaps because the majority
of Melastomataceae are shrubs or understory trees
with terminally positioned infructescences, they are
unsuited for foraging monkeys and bats. Also, the
taste of the mostly sweet, watery melastome berries
may not be to the liking of monkeys, which ap-
parently prefer slightly acidic fruits (Sourd & Gau-
tier-Hion, 1 ).
Fruits that have fallen to the ground are often
eaten by turtles (Moskowitz, pers. comm.; Roos-
malen, pers. comm.), lizards (W. Magnusson, pers.
comm.), rodents (Magnusson & Sanaiotti, 1987),
tapirs (Huber, 1910), and ants (pers. obs.).
SEED DISPERSAL IN MEMECYLACEAE
All Memecylaceae have berries, ranging in size
from 0.5 to 10 cm long; color at maturity is most
commonly yellow to red, less often it is purple-
black to black (Morley, 1976). The smaller-fruited
species are surely bird dispersed; some larger-fruit-
ed ones are monkey-dispersed (Roosmalen, 1985).
Fish eat the fruits of at least one riverine Mouriri
species (Goulding, 1980), which is curious, since
Morley (1976) reported that two other species are
used for poisoning fish.
REPRODUCTIVE BIOLOGY AND THE EVOLUTION OF
MELASTOMATACEAE AND MEMECYLACEAE
Floral morphology in Melastomataceae and Me-
mecylaceae can only be understood as the result
of coevolution between the earliest ancestors of
these groups and pollen-collecting bees. Flowers of
the Old World members of both families have the
same basic construction as those of their New World
relatives and, although little information is available
on their floral biology, van der Pijl's (1939) detailed
description of the pollination mechanism in some
species of Osbeckia, Medinilla, and Melastoma
makes it likely that they are pollinated in the same
manner as the New World ones. The pollen offered
in the poricidal stamens of both families is acces-
sible exclusively to bees, but not to many of the
most common ones, such as the numerous species
of Trigona and the paleotropical Apis, which ap-
parently do not vibrate stamens. Most Melasto-
mataceae and Memecylaceae have “modern” pol-
len flowers in the sense of Vogel (1978), in which
the visitor is forced into a fixed position while
harvesting the reward and in which the position of
the stigma is of relatively little consequence be-
cause of the deposition of pollen on a large part
of the visitor's surface
There appears to be little opportunity for par-
titioning the bee body. Sharing of pollinators, noted
rather frequently among sympatric buzz flowers
(Linsley € Cazier, 1963; Macior, 1970, 1971;
Thorp & Estes, 1975; Lumer, 1982; Renner,
1984), results in hybridization in the absence of
genetic barriers. This is consistent with the fact
that systematists working with Melastomataceae
and Memecylaceae often notice hybrids (Kral &
Bostick, 1969; Whiffin, 1973; Morley, 1976; Al-
meda, 1978; Solt & Wurdack, 1980; Renner, in
press). The data on Melastomataceae breeding sys-
tems corroborate the suggestion that apomixis may
be more widespread in the tropics than formerly
thought (Kaur et al., 1978; Ashton, pers. comm.,
1987). Apomictic seed production would make such
species independent of pollinators, while retaining
the advantages of producing seeds, i.e., the poten-
tial for dispersal and dormancy. Most notably, it
would give them the capacity to build up a new
population from a single propagule.
Statements that “details of the structure of the
anthers doubtless relate to mechanisms of polli-
nation" (Cronquist, 1981) or “in a family, such
as the Melastomataceae, where floral evolution has
been extensive, one may logically conclude that
the diverse floral types represent adaptations to
different pollination systems” (Almeda, 1977) are
not corroborated by field data. Rather, Melasto-
mataceae seem to confirm Macior's (1971) sug-
gestion that buzz pollination is so successful a sys-
tem that, once it is established, hardly any other
pollination mechanism evolves, even in species-rich
groups. Compared with other families, such as
Lecythidaceae, Gesneriaceae, and Bignoniaceae,
for which the overall pollination spectrum is fairly
well known, Melastomataceae and Memecylaceae
show little diversification in floral morphology and
pollination strategies. In this they resemble Mal-
pighiaceae (Anderson, 1979) and Solanaceae (Sy-
mon, 1979), which also have relatively specialized
pollination systems and faithful bee pollinators. Such
ack of diversification could be interpreted as the
result of being stuck on an adaptive peak.
Melastomataceae that offer nectar are pollinated
by a broader range of pollinator classes, namely
by hummingbirds, bats, rodents, and bees; this
statement applies to the individual species as well,
several of which have more than one important
pollinator type, for instance birds and bats in
Tibouchina grossa and bees and rodents in Blakea
chlorantha. Cruden (1972) suggested, as a possible
514
Annals of the

ecological significance for nectar production at
higher altitudes, that under adverse climatic con-
ditions the homoiothermic birds and mammals may
be more reliable pollinators than bees. If valid, this
explanation would apply to all now known nectar-
producing Melastomataceae, except the species of
Miconia.
Whether the thousands of pollen-only Melas-
tomataceae derived from ancestors with nectar
flowers or whether the proto-Melastomataceae nev-
er possessed nectaries (as suggested by Vogel, 1978
is a difficult question. Phylogenetically, the extant
nectariferous species belong to groups not closely
related: Meriania and Centronia are in the cap-
sular-fruited Merianieae (as is Axinaea, which
probably also has some nectariferous species, see
above) Brachyotum and Tibouchina are in the
likewise capsular-fruited Tibouchineae; Chalybea,
Huilea, and Miconia are in the berry-fruited Mi-
conieae; and Blakea is in the also berry-fruited
Blakeeae. Thus nectar production occurs in at least
five evolutionary lines: the first leading to Meriania
and Centronia (which are not closely related to
each other) the second to Brachyotum and
Tibouchina (the first genus is a segregate of the
second; Wurdack, 1954), the third to Chalybea
and Huilea (two intimately related genera), the
fourth to Miconia (with 1,000 D only two
of which to date are securely known to produc
nectar), and the fifth to Blakea. dila could
have n ida in all these lineages.
oblem is confounded by the slits observed
—
in the hea of some non-nectariferous Mela-
stomataceae exactly in the same position as in some
of the nectariferous species, where nectar is se-
creted through them. They occur in species of
Heterocentron (Tibouchineae), Bertolonia (Ber-
tolonieae), and Centradenia (Microlicieae) and in
the paleotropical genera Medinilla and Dissotis
(compare above under nectariferous melastomes)
and may be rudimentary, nonfunctional nectaries.
Thus, to date, only in two of the neotropical tribes—
the small Rhexieae with 64 species and the Cy-
phostyleae with nine species—are nectar produc-
tion or presumed rudimentary nectaries absent. In
view of the presence of nectaries in at least five
neotropical lineages and the indications of their
former presence in two further ones, their parallel
independent origin becomes hard to accept. In-
stead, I suggest that the capacity for developing
nectaries is basic in the Melastomataceae but sup-
pressed in most modern members.
To understand the origin of the memecyloid
connective gland, whatever the chemical compo-
sition of its secretion, the following observations
seem relevant. Functioning nectaries have been
observed on the hypanthia of Memecylon edule
Roxb. (= M. ramiflorum Desr.; Burck, 1 )an
M. floribundum Blume (Zimmermann, 1932). Also,
I have frequently seen ants on the hypanthia of
Mouriri nervosa, which may be an indication that
this neotropical Memecylaceae also secretes e
albeit in minute quantities. Evolutionarily, the c
pacity to secrete minute quantities of dece
directly through the hypanthium epidermis, with-
out conspicuous morphological structures, may be
correlated with the development of the staminal
glands. However, data on the pollinators and the
chemical composition of the exudates of paleo-
tropical Memecylaceae are needed before the sig-
nificance of the staminal glands in the family as a
whole can be assessed. The Memecylaceae have
a. 340 Old World and 89 New World species,
and it should be noted that, in the opinion of Morley
(1953), the New World Memecylaceae are more
basal than the Old World ones.
There is a great amount of parallelism between
the Old World and the New World tribes in the
Melastomataceae: the Oxysporeae, Sonerileae, Dis-
sochaeteae, and Osbeckieae resemble more or less
closely the Merianieae, Bertolonieae, Miconieae,
and Tibouchineae, respectively, of the New World
(Gleason, 1932). Based on wood anatomy, the dif-
ferentiation into at least some of these tribes and
into Melastomataceae and Memecylaceae occurred
before the breakup of Pangaea (Vliet et al., 1981).
However, the coevolutionary relationships between
bees and proto-Melastomataceae, which are a con-
O
ditio sine qua non for the evolution of the mela-
stome androecium, can only have begun during
the mid-Cretaceous when bees arose (Michener,
1979). The mid-Cretaceous may thus have been
the time when the ancestors of these families
switched from nectar-reward flowers to pollen-re-
ward flowers (with the pollen presented in poricidal
anthers and available only to bees). Likely, the
Melastomataceae and Memecylaceae originated
during Aptian times (lower mid-Cretaceous, 11
million years before present), when the gap between
Brazil and Ghana was still very narrow; their east
and west Gondwanian lineages, probably coevolved
in parallel with the earliest bees. The oldest fossil
melastome leaves are known from the early Eocene
(Hickey, 1977), about 53 million years before pres-
ent, and Eocene and Miocene leaves occur widely
scattered throughout the Northern Hemisphere
(Wurdack & Kral, 1982). Therefore, members of
the family (and some of their pollinators?) at one
time may have dispersed via Europe between North
America and Africa.
The Melastomataceae, with two-thirds of their
species in the Neotropics, have much of their di-

versity centered in areas of varied topography —
the Andes, Guayana, and south-central Brazil. The
neotropical Memecylaceae, on the other hand, are
centered in the Amazonian lowlands, where they
appear adapted to different soil types (pers. obs.).
The very early shift from anemochory to zoochory
in the Melastomataceae was probably one of the
reasons for their success in the understory of closed
forests, where animal dispersal is more advanta-
geous than wind dispersal. (The capsular-fruited
tribes are much more diverse in open habitats and
have relatively few species in forests.) The crucial
points in the radiation of large groups within the
Melastomataceae, besides their different seed-dis-
persal strategies, have been the acquisition of par-
ticular plant architectural, indument, and leaf ve-
nation characters. Because adaptations to different
pollinator types played such a limited role in the
radiation within the two families, the floral biolog-
ical data cannot be used to support either of the
two suggested phylogenies for the Melastomataceae
(Wurdack in Welle & Koek-Noorman, 1981; Vliet
et al., 1981).

explanation for the diversity of nectary types within the family and for the scattered phylogenetic positions of nectar
producing taxa
The family Melastomataceae, with ca. 200 gen-
era and 4,500-5,000 species, is the largest in the
order Myrtales. This primarily tropical family is
distributed worldwide but particularly well repre-
sented in tropical and subtropical areas of the New
World. Most members of the family produce no
floral nectar, relying instead on pollen as the prin-
cipal pollinator reward (for review see Renner, this
volume). Species in at least two genera, Tibouchina
(= Purpurella) (Ule, 1896) and Brachyotum
(Lagerheim, 1899), however, have long been known
to produce nectar. Additional observations of nec-
tar production, or presumed production, have been
made more recently on these and several other
melastome genera, including Blakea (Lumer, 1980;
Lumer & Schoer, 1986), Huilaea (Snow & Snow,
1980), and Miconia (Mori & Pipoly, 1984). Most
reports that note the location of nectar secretion
within the flower generally found the nectar to
emanate from the stamens. This strongly contrasts
with the situation in most myrtalean families in
which floral nectaries are located either on the floral
tube, the gynoecium, or at the floral tube-gynoe-
cium junction.
oral nectaries of Melastomataceae have been
little studied, and nothing has been reported pre-

viously about their anatomical structure. The pri-
mary purpose of this study is to elucidate the struc-
ture of Melastomataceae nectaries through
anatomical examination and to confirm the unusual
location of nectar secretion through field obser-
vations. Our investigation of floral nectary struc-
ture extends to representative genera of Me-
a family traditionally included in
Melastomataceae as a tribe or subfamily. The an-
mec ylaceae,
ther connective of Memecylaceae contains a dis-
tinctive depressed gland structure that had previ-
ously been described as a nectary (Burck, 1891;
Subramanyam, 1949). In Mouriri, however, these
glands have recently been found to secrete a lipid-
rich substance, suggesting that they are elaiophores
(Buchmann & Buchmann, 1981
MATERIALS AND METHODS
We examined anatomically flowers of 40 species
in 17 genera of Melastomataceae, representing
known nectar producers and genera and species
not reported to secrete nectar. In addition, six
species of Memecylaceae in three
investigated. FAA-fixed collections were made by
the authors and by numerous collaborators world-
wide (Table
After dehruration through a t-butyl alcohol se-
ries and embedding in Paraplast with MP 57-
58 C?, flowers (and sometimes stamens alone) were
enera were
sectioned transversely and longitudinally at 8-10
um thickness; the sections were stained with he-
matoxylin, safranin, and fastgreen FCF and were
mounted with Entellan. Dark staining by hema-
toxylin represents a concentration of cytoplasm in
cells, indicating high metabolic activity such as seen
in active nectaries. In other families of the Myr-
tales, this staining method has fully demonstrated
the location and size of nectariferous tissue (Tobe,
pers. obs.); if present, nectaries are thus easily
distinguished from other tissue by their dense stain-
ing.
We noticed that certain species, particularly
those known to secrete nectar, have a conspicu-
ously thickened staminal vascular bundle. Thus,
for comparative purposes, the thickness of the
staminal vascular bundle is presented as a relative
value (Table 1). The “relative thickness" of stamen
vascular bundles is calculated as: radial thickness
of the vascular bundle (t)/radial thickness of the
filament (T). Calculations were made on the basis
of two or three stamens. Relative thickness values
are presented as a range, since the thickness of
the filament and the vascular bundle can differ at
varying points along the same filament.
Field observations of nectar secretion in
Brachyotum, Chalybea, and Tibouchina were
conducted while field collecting floral material for
this study. Fresh flowers were examined for evi-
dence of nectar, and the location of nectar secretion
within the flower was noted. Nectar quantity and
sugar concentration were measured using micro-
capillary tubes and a Reichert temperature-com-
pensated hand refractometer (model 10431). Nec-
tar sugar concentration measurements (% brix)
were subsequently converted to sucrose-equiva-
lents (weight by total weight).
RESULTS
We did not detect densely staining structural
nectaries in the flowers of any of the species ex-
amined of Melastomataceae and Memecylaceae.
Three significant features were noted, however.
First, stamens of some melastomes, particularly
those known to secrete nectar, have a markedly
thickened vascular bundle in relation to the fila-
ment or anther connective. Relative thickness of
staminal vascular bundles of nectar-producing and
non-nectar-producing species are presented in Ta-
ble 1. The relative thickness values of staminal
vascular bundles in nectar-producers normally ex-
ceed 0.3 (mean 0.34), whereas
stomes examined range between 0.1 and 0.3 (mean
0.23), a statistically significant difference (P <
0.001). Second, although no densely staining struc-
most other mela-
—
tural nectaries were found, many of these thickened
vascular bundles showed relatively dark-staining
phloem cells, indicating that they are cytoplasm
rich and may be fulfilling a nectary function. Third,
many of the nectar-secreting species have external
slits that develop on or near the geniculum of the
filament and that may represent a nectar emission
pathway.
Information on the site of nectar secretion and
on known or putative pollination vectors for nectar-
producing Melastomataceae is summarized in Table
2. Examined genera that are known or strongly
suspected to produce nectar are discussed individ-
ually below. Members of several other genera may
also secrete nectar but were not examined. These
include two additional Andean genera that hum-
mingbirds have recently been observed visiting,

to produce nectar. Two additional nectar-producing
species have recently been reported, B. austin-
smithii Standl. and B. penduliflora Almeda (Lu-
mer & Schoer, 1986). There is some disagreement
concerning the site from which nectar is secreted
in this genus. Lumer (1980, and pers. comm.,
1985) stated that in B. chlorantha nectar appears
to be secreted in the area at the base of the stamens,
either at the junction of the filament and floral tube
or at the base of the filaments. According to Haber
(pers. comm., 1985), however, nectar is secreted
on the abaxial surface of the filaments (the side
facing the corolla wall), with the nectar forming
thick droplets between the filament and the corolla.
Anatomical sections of Blakea chlorantha flow-
ers do not show a densely staining nectary any-
where on the floral tube wall (Fig. 1), nor do sta-
mens have an externally or internally differentiated
nectariferous structure (Figs. 2, 3). Stamens are
folded inward in bud, with a geniculum present just
above the midpoint. Slitlike structures are present
on the adaxial surface of the geniculum (arrows in
Figs. 1-3). The relative thickness value of the
vascular bundles is fairly low (0.21-0.27) com-
pared with other nectar producers (Fig. 5). These
vascular bundles, however, are relatively densely
staining, particularly in the upper part of the fil-
ament and at the connective (Figs. 3-5). A major
part of the staminal vascular bundle appears to
consist of small,
cular bundle are not specialized (Figs. 4, 5), sug-
gesting that they are not nectariferous.
Stamens of Blakea sp. nov. (fide F. Almeda)
and B. foliacea are folded inward in bud at the
anther—filament junction, and filament slits are not
present. Although, like B/akea chlorantha, they
have a thin more or less densely staining vascular
bundle, they differ in that the staminal vascular
bundle is surrounded by a thick-walled tanniferous
epidermis and by some underlying tanniferous cell
layers. Blakea sp. nov. and B. foliacea stamens
are unlikely to secrete nectar through such tan-
niferous tissue, and nectar production has never
been reported in either of these two species.

gated in the field were found to produce nectar,

confirming previous reports (Lagerheim, 1899; Vo-
gel, 1957; Wurdack, 1965), and it is likely that
this entire Andean genus is nectariferous. From
field observations, the nectar appears to be secreted
by the filament at the slitlike structure located on
or just below the geniculum on the adaxial filament
face (Fig. 6) and forms large droplets suspended
between adjacent pairs of filaments. Nectar con-
centration ranged from a high of 20-22% sucrose-
equivalents in B. ledifolium (Desr.) Triana to a
low of 15-16.5% in B. campanulare (Bonpl.)
Triana, values consistent with most hummingbird-
pollinated flowers (Baker, 1975).
natomical sections of stamens do not show any
differentiated nectariferous structure in the fila-
ments. Stamens of Brachyotum ledifolium have a
thick vascular bundle running the length of the
filament (Fig. 7) to the connective (Fig. 8). The
staminal vascular bundle is densely staining and
contrasts with the surrounding nonspecialized
parenchyma cells. All other examined species of
Brachyotum contain a similar thick, densely stain-
ing staminal vascular bundle: B. campanulare (Fig.
10), B. lindenii Cogn., B. microdon (Naud.) Triana,
and B. sanguinolentum (Naud.) Triana (Fig. 9).
This similarity in staminal anatomy suggests that
all these species exude nectar from the filament.
Chalybea. | Chalybea is a monotypic genus of
the Colombian Andes closely related to, if not con-
generic with, the nectar-producing genus Huilaea.
Poorly known and consisting only of C. corymbif-
era Naud. (= Pachyanthus corymbiferus [ Naud. |
Cogn.), Chalybea recently has been resurrected
on the basis of material newly collected for this
study (Wurdack, 1988). We have observed nectar
secretion from C. corymbifera and measured the
nectar sugar concentration at 16.5% sucrose-
equivalents. Pinpointing the site of secretion is
problematic. Nectar was collected from the summit
of the inferior ovary; however, the nectar was
observed and measured several hours after the
normally pendulous flowers were collected and could
have migrated to this location. Stamens are bent
inward in bud and have neither a pronounced ge-
niculum nor filament slits (Figs. 11, 12). Anatom-
ical sections do not show a differentiated nectarifer-
ous structure at the ovary summit (Fig. 11). While
stamens do not have either externally differentiated
structures or densely staining nectariferous tissue
(Figs. 11, 12), they do contain a thick vascular
bundle running through the filament (Fig. 14) to
the connective (Fig. 13), suggesting staminal se-
cretion. Tanniferous parenchyma cells surrounding
the staminal vascular bundle appear unfavorable

for secretion of nectar. These tanniferous cells,
however, are much less conspicuous in the lower
part of the filament, and nectar thus may exude
from the filament in this location, perhaps ac-
counting for its observed presence on the ovary
summit.
Huilaea. Snow & Snow (1980) reported nectar
production by Huilaea macrocarpa Uribe and
measured the nectar sugar concentration to range
from 12 to 16% with a mean of 13.4%. No in-
formation was provided as to the precise location
of nectar secretion in these pendulous flowers.

tions of nectar secretion in T. grossa differ somewhat
from those of Vogel (1957), who considered the
nectar to exude from the inner wall of the floral
tube below the insertion of the stamens. 7ibouchina
grossa flowers are open-campanulate and oriented
horizontally with all stamens arranged in a half-
circle in the lower side of the corolla. We observed
nectar droplets forming on the adaxial surfaces of
the filaments near the geniculum. The drops are
at first suspended between adjacent filaments and
occasionally between the filaments and style. The
rather copious nectar then flows down the filaments
to collect either in the floral tube or on the convex
lower petals. We measured sugar concentration of
T. grossa nectar at 14.5% sucrose-equivalents.
No densely staining differentiated structure was
found in the filaments of Tibouchina grossa (Fig.

however, we found cultivated material of M. mag-

secrete nectar from the petal tips. Anatomical in-
vestigations of this very unique nectar secretion
method are currently under way (Tobe et al., in
prep).
Miconia. |n discussing a mass flowering episode
of Miconia minutiflora (Bonpl.) DC, Mori & Pipoly
(1984) reported the presence of nectar as a pol-
linator reward in this species. In other localities,
however, this lowland species has not been found
to secrete nectar (Renner, 1983).
Only young buds of Miconia minutiflora were

Floral Nectaries in Melastomataceae
available for the present study. Anatomical sections
of this material indicate no structure likely to pro-
duce nectar in either the stamens or around the
floral tube-gynoecium junction (Fig. 18). Flowers
are very small, with the filaments supplied by a
relatively thin vascular bundle (Fig. 19). Anatom-
ical sections show, however, that M. minutiflora
has a remarkably conspicuous stigma supplied by
ample, densely staining vascular tissue (Fig. 18).
Hummingbirds have been observed visiting Mi-
conia melanotricha (Triana) Gleason (Almeda, pers.
comm., 1986), and this species may produce nec-
tar. The flowers appear morphologically well suited
for hummingbird pollination, given their large size
(10-15 mm in diameter an -25 mm long) and
red petals. This species also has longitudinally de-
hiscent anthers rather than the apically poricidal
anthers typical of bee-pollinated melastomes. An-
atomical sections do not show densely staining
structures or tissue, and the stamens have a thin
vascular bundle (Fig. 21). As in M. minutiflora,
however, the stigma and supporting vascular tissue
are unusually densely staining (Fig.
iconia robinsoniana Cogn. was reported to
produce nectar in a survey of the foraging ecology
of the Galápagos Islands carpenter bee, Xylocopa
darwinii (Linsley et al., 1966). Subsequent obser-
vations of this species have not reconfirmed the
presence of nectar (McMullen, pers. comm. in Ren-
ner, this volume). During our own field investiga-
tions of this species, no suitable material could
located to resolve this question. An additional, as
yet unidentified, Miconia species from lowland
Amazonia has recently been reported to produce
nectar (Roubik, pers. comm. in Renner, this vol-
ume).
MEMECYLACEAE
Memecylon and Mouriri have a peculiar de-
pressed gland on the backside of the anther con-
nective (Figs. 22, ). This structure was early
escribed as a nectary (Burck, 1891; Subraman-
yam, 1949; Venkatesh, 1955) but recently has
been hypothesized to be an elaiophore, or oil-pro-
ducing gland (Buchmann & Buchmann, 1981).
Anatomical sections reveal this gland to be com-
posed of more or less radially enlarged epidermal
cells, which are clearly distinguishable from other
cells of the connective (Figs. 23, 25).
Pternandra is variously included in or excluded
from the Memecylaceae. Its uncertain status is
based largely on the absence of the anther con-
nective glands found in other members of Me-
mecylaceae. The two species examined in this study,
P. caerulescens Jack. and P. echinata Jack., lack
these gland structures on the surface (Figs. 26,
2'7) and in section (Fig. 28)
DISCUSSION
POSITION AND STRUCTURE OF FLORAL
NECTARIES IN MELASTOMATACEAE
The present study shows that, in contrast to
nearly all other myrtalean families, Melastomata-
ceae lack histologically differentiated nectariferous
tissue either on the inner surface of the floral tube,
on the gynoecium, or at the floral tube-gynoecium
junction. While nectar production in Melastoma-
taceae is rare, a diversity of unusual nectary types
are implicated, including secretion from the sta-
mens, petals, and perhaps stigmas. Most docu-
mented nectar-producing melastomes secrete nec-
tar from the stamens, although we did not find any
differentiated nectariferous structures or tissue in
that organ. On the basis of observations and an-
atomical structure, we thus conclude that in most
nectariferous Melastomataceae nectar is produced
by a nonstructural nectary consisting solely of the
staminal vascular bundles.
Compared with melastome species generally,
stamens of nectar-producers have a much thicker
vascular bundle containing many small, densely
staining cytoplasm-rich phloem cells. An ultra-
structural survey of these cells could offer addi-
tional evidence of their nectar-secreting capability,
since there is a clear connection between cytolog-
ical constituents and processes of nectar secretion
(for review of ultrastructural features see Fahn,
1979).
The nonlocalized nature of these androecial nec-
taries may help resolve the g reports about
the specific sites of nectar secretion (Table 2). If
nectar is produced by the staminal vascular bundle,
it could emanate from almost anywhere along the
stamen. Additionally, if the direction of the nectar
stream within a stamen is affected by gravity, the
d
secretion site could differ between stamens an
among individual flowers.
Several observers, including one of us (B.A.S.),
have noticed that in certain genera (e.g., Brachy-
otum and Tibouchina) the location of nectar se-
cretion appears to be closely associated with a small
slit in the adaxial surface of the filament (see arrows
in Figs. 1-3, 6). The development and significance
of these slits is somewhat controversial. We found
no anatomical differentiation of this structure. Since
stamens in Melastomataceae are folded or bent
inward in bud, becoming more or less straight at
anthesis, the observed slitlike structures may form
spontaneously and be unrelated to nectar secretion.

Such slits are, in fact, reported in some species not
known to secrete nectar (Renner, this volume).
However, an apparent association of these slits with
nectar-producing species, their absence in related
non-nectariferous species (e.g., Blakea chlorantha
vs. B. sp. nov. and B. foliacea), and field obser-
vations of nectar droplets formed precisely at these
indentations strongly argue for a role in nectar
secretion ese structures may form through a
deterlonition of a small amount of tissue on the
inner side of the geniculum, providing an exit path-
way for nectar produced by the staminal vascular
bundle. Clearly, a systematic survey of the occur-
rence of these slits throughout the Melastomata-
ceae would be useful in clarifying their role.

the other confirmed nectar-producers we investi-
gated. If nectar production in this species is re-
confirmed, the conspicuous stigma, which is sub-
tended by cytoplasm-rich vascular tissue, should
be closely examined for a possible secretory role.
Stigmatic nectar secretion is rare within the an-
giosperms but occurs in Asclepiadaceae and Ara-
ceae (Fahn, 1979).
EVOLUTION OF FLORAL
MELASTOMATACEAE
NECTARIES IN
Nectaries generally consist of an epidermis sub-
tended by specialized parenchyma cells (Esau, 1977;
Volume 76, Number 2
1989
Stein & Tobe
Floral Nectaries in Melastomataceae
529
Fahn, 1979). The phloem-based nectaries we have
found in Melastomataceae, which have no struc-
turally differentiated parenchyma, are a rather ex-
treme deviation from this typical structure. The
nonstructural androecial nectaries found in Melas-
tomataceae are particularly anomalous in Myrtales,
where, of the 14 families currently included in the
order (Dahlgren & Thorne, 1984), only Melasto-
mataceae, Memecylaceae, and Rhynchocalyca-
ceae lack densely staining structural nectaries. Eyde
(1981) has discussed evolutionary shifts in the lo-
cation of floral nectaries in flowers of various myr-
talean families and concluded that the ancestral
site of nectar secretion for Myrtales, as for many
other dicots, is the junction between the gynoecium
and the floral tube or, in tubeless flowers, the junc-
tion with the androecium. From this ancestral po-
sition, nectaries evolutionarily have migrated onto
the floral tube, or even onto the androecium in
some tubeless species of Lopezia and Epilobium
of the Onagraceae (Eyde & Morgan, 1973; Eyde,
1981). Androecial nectaries are also found in other
groups, including virtually all members of the Cary-
ophyllales (Zandonella, 1977
droecial nectaries in these other families are more
typical differentiated structures and thus not com-
parable to the nonstructural androecial nectaries
of Melastomataceae, which are certainly unique
within the Myrtales and perhaps among angio-
sperms as a whole.
Given the ancestral myrtalean nectary type and
position proposed by Eyde (1981), it seems clear
that structural nectaries were lost in the evolu-
. However, the an-
tionary lineage ancestral to Melastomataceae and
Memecylaceae. Such nectaries appear to have been
lost independently in the lineage leading to Rhyn-
chocalycaceae (a monotypic family consisting only
of the South African Rhynchocalyx lawsonioides
Oliver), since on many other grounds this family
is more closely related to other members of the
Myrtales than to Melastomataceae (Tobe & Raven,
1984).
Pollinator interactions appear to have played a
key role in both the ancestral loss and subsequent
re-evolution of nectaries within the Melastomata-
ceae. Melastomataceae are, on the whole, a famil
uniquely suited for bee pollination. The distinctive
poricidally dehiscent anthers are directly related
to vibratile extraction of pollen by bees, a phe-
nomenon known as buzz pollination. Bees foraging
for pollen in this manner rarely forage simulta-
neously for nectar, and then only to mix it with
the pollen to improve the pollen's handling prop-
erties (Buchmann, 1983). Although poricidal an-
thers are found in numerous angiosperms (for re-
view see Buchmann, 1983), few plant families are
so completely characterized by this feature as Me-
lastomataceae. Given the widespread distribution
of poricidal anthers within all lineages of Melas-
tomataceae, this feature appears to be the ancestral
condition for the family. Thus, if buzz pollination
became established in the lineage ancestral to Me-
lastomataceae, there would be little or no selective
advantage in maintaining energy-expensive nec-
taries. By attracting undesirable and potentially
destructive floral visitors, nectaries may even have
been selected against in protomelastomes.
Nectaries appear to have re-evolved indepen-
dently in several distinct lineages within the family,
most of which share certain ecological and repro-
ductive traits. Cruden (1972) has pointed out the
potential reproductive advantage ensuing from a
shift from bee to bird pollination in wet-tropical
montane ecosystems. Similarly, Heinrich & Raven
1972) have noted the increased energy reward
necessary to attract pollinators operating at higher
elevations and to support vertebrate rather than
invertebrate pollinators. Nectar, composed prin-
cipally of carbohydrates, is a much richer energy
source than pollen and is almost invariably the
floral reward used to attract vertebrate pollinators.
Not surprisingly, most confirmed nectar-producing
Melastomataceae (species of Blakea, Brachy-
otum, Chalybea, Huilaea, and Tibouchina) occur
at high or relatively high elevations, and are known
or presumed to be pollinated by vertebrates (Table
—
According to traditional and recent classification
systems for the family (Cogniaux, 1891; van Vliet
et al., 1981; Wurdack, 1980), confirmed nectar-
producing Melastomataceae are found in at least
four different tribes: Blakeae, Dissochaeteae, Mi-
conieae, and Tibouchineae (see Table 1). The phy-
monophyletic lineage within the family. In addition,
the majority of genera in these four tribes are not
known to produce nectar. Except for the lowland
species of Miconia discussed above, most of the
nectar-producing taxa can be viewed as ——

pollination systems and ecological/ aia! pubs
erences. With regard to the latter, the Central and
northwestern South American montane terrains that
are inhabited by many of these species (and, if the
above interpretation is correct, may have provided
the ecological impetus for the development of nec-
tar rewards) are generally more recent (Zeil, 1979)

than the origin of the Melastomataceae, fossils of
which are known from as early as Eocene times
(Hickey, 1977).
wo hypotheses can be advanced to account for
the unusual systematic distribution of nectaries
within the family. The first is that such nectaries
are the basal condition in Melastomataceae and
have been lost in the vast majority of species. Civen
the structural nectaries present in other families
of Myrtales and the rather specialized morpholog-
ical state of most of the nectariferous species, how-
ever, such an interpretation is untenable. Renner
(this volume) advocates a modified version of this
hypothesis, suggesting that “the capacity for de-
veloping nectaries is basic in the Melastomataceae
but suppressed in most modern members.” This
supposition seems equally difficult to accept. Rath-
er, we propose a second hypothesis, which is that
nectaries have evolved independently a number of
times within the family and developmentally have
followed the easiest course available. T
evidence point to this. First, three different nectary
types have developed within the family, each in-
e. Two lines of
volving different floral organs (stamens, pistil, pet-
als). Although rare within angiosperms, the most
common melastome nectaries, nonstructural an-
droecial nectaries, involve very little modification
of existing structures and thus appear to be an
ipd developed solution to producing nectar. It is
cult, however, to reconcile this view of the ease
of developing such nectaries with the relative rarity
of nonstructural androecial nectaries in the angio-
sperms as a whole
SYSTEMATIC IMPLICATIONS OF NECTARY
ANATOMY FOR MEMECYLACEAE
Memecylaceae traditionally have been included
in Melastomataceae as a tribe or subfamily (e.g.,
Cogniaux, 1891; Morley, 1976). Based on floral
nectary characters, Memecylaceae agree with Me-
lastomataceae in completely lacking densely stain-
ing structural nectaries. The term “disc” has some-
times been used to describe certain structures within
the flowers of Memecylon (see Bremer, 1983).
Given the complete lack of nectariferous tissue,
this term should, however, be avoided. As previ-
ously discussed, loss of structural nectaries seems
to be a feature ancestral for Melastomataceae, and
this is probably also the case for Memecylaceae.
We regard loss of structural nectaries as a syn-
apomorphy uniting these two families.
Memecylaceae have generally been circum-
scribed to include the Old World Memecylon and
the New World Mouriri and Votomita, all con-
taining anther connective glands. Based on obser-
vations of Mouriri myrtilloides (Sw.) Poir, Buch-
mann & Buchmann (1981) suggested that the
connective glands of Memecylaceae are elaio-
phores that secrete lipids for nutritional use b
pollinating bees, primarily in larval o
Although the secretion is lipid rich, its chemic
complexity and the presence of components seem-
ingly toxic to insects have led others to be cautious
about this interpretation (Renner, this volume;
Simpson & l
Morley (1976) considered these distinctive but
little-understood connective glands to be one of the
most characteristic features of the "Memecyleae'
(7 Memecylaceae), even though they are occa-
sionally lost, as in Mouriri exadenia Morley.
Whatever its taxonomic rank, the group is now
generally considered to include additional genera,
among them Pternandra, which lacks connective
glands (Dahlgren & Thorne, 1984). The present
study reconfirms this observation: all examined
species of Memecylon and Mouriri have anther
glands on the backside of the connective, whereas
all examined species of Pternandra lack them.
Therefore, even if Pternandra is aligned with Me-
mecylon, Mouriri, and Votomita at the familial
level, evolution of the anther glands appears re-
stricted to the lineage including the three last-
mentioned genera. Available evidence from stam-
inal anatomy does not resolve the correct familial
placement of Pternandra but does suggest that if
included in Memecylaceae, it should be regarded
as the sister group to the rest of the family. This
is generally the approach taken by van Vliet et al.
(1981) in placing Pternandra in its own tribe Pter-
nandreae of their “Memecyloideae” (= Memecy-
laceae).

Fuchsia is a distinctive genus of Onagraceae
with close to 105 species belonging to ten sections
(Berry, 1982; Berry et al., 1988). The genus con-
sists mostly of mesic shrubs confined to cool, moist
habitats, with nearly 34 of the species concentrated
in the tropical Andes. The remaining species occur
in Mexico and Central America, Hispaniola, south-
eastern Brazil, the southern Andes, New Zealand,
and Tahiti.
In recent years, Fuchsia has been the subject
of a series of studies designed to refine the tax-
onomy and to improve our understanding of the
evolutionary relationships within the group. A com-
prehensive analysis of leaf flavonoids (Averett et
al., 1986) confirmed the distinctiveness of the New
Zealand species of the widely disjunct sect. Skin-

array of species have helped to define sectional
limits by detecting consistent differences in viscin
types, aperture number, and grain size
(Skvarla et al., 1976, 1978; Nowicke et al., 1984;
Praglowski et al., 1983). Systematic revisions for
seven of the ten sections in the genus have been
completed, based on broad cytological surveys, a
thorough review of the major collections of her-
barium specimens, and extensive field examination
of natural populations (Breedlove, 1969; Berry,
1982, 1985; Breedlove et al., 1982; Berry et al.,
1988). The present study uses the same method-
ology to produce a revision of the species of sect.
Quelusia, a group centered in southeastern Brazil
and forming the largest section outside of the trop-
ical Andes.
A better understanding of the systematics of
sect. Quelusia is particularly desirable, as the species
form a closely related, yet unspecialized group that
may have retained many of the primitive char-
acters of the genus. Biogeographically, the section
is confined to ancient forest areas in the southern
Andes and in southeastern Brazil that show clear
austral-Antarctic affinities. Ultimately, this may
have been the source area from which other sec-
tions differentiated and spread both to Australasia,
when more or less direct overland connections were
possible across Antarctica until the mid-Tertiary,
and to Central America, where several small sec-
thread
tions presently occur
orticulturally, most of the hundreds of hybrid
Fuchsia cultivars have been derived primarily from
members of sect. Quelusia (Reiter, 1944), yet there
has been much confusion as to which taxa were
involved in the early crosses. Accurate information
on the different native species of sect. Quelusia
can also be expected to stimulate interest in their
preservation, cultivation, and use in hybridization
for new ornamental cultivars.
In the only recent monograph of Fuchsia, Munz
(1943) recognized five species in sect. Quelusia,
together with Fuchsia hybrida Hort. ex. Vilm., a
name used to encompass most of the common
garden hybrids. Fuchsia magellanica and F. regia
included three and four varieties, respectively; these
species have the broadest geographical distributions
in the genus and also show complex patterns of
morphological variation. In this study, Fuchsia
magellanica is treated as a single, cytologically
uniform, polymorphic species with no clear geo-
graphical pattern of differentiation. Fuchsia regia,
on the other hand, has tetraploid and octoploid
populations, with geographically differentiated
variants that are treated here as comprising three
intergrading subspecies. Both F. alpestris and F.
glazioviana are reinstated as distinct species, and
two previously unrecognized species are described,
F. brevilobis and F. hatschbachii. As herein de-
limited, sect. Quelusia consists of 11 taxa, with
nine different species.
HABITAT AND DISTRIBUTION
Fuchsia sect. Quelusia is an entirely Southern
Hemisphere group of species, bs. a latitudinal
range extending from 18*S to
outh America in two large vi widely disjunct
areas: the southern, temperate Andes of Chile and
Argentina, and the coastal mountains and high
plains of southeastern Brazil (Fig. 1).
The only species occurring in the southern An-
des is F. magellanica, which is characteristic of
the wet, temperate, Valdivian forests that are cen-
tered in the Región de Los Lagos of Chile. These
forests are considered to be relicts of an ancient
vegetation type that includes many taxa of Aus-
tralasian affinity, such as Nothofagus, Drimys,
Podocarpus, and Araucaria (Rambo, 1951;
Hueck, 1972; Lötschert, 1981). Fuchsia magel-
lanica also extends farther north into drier areas
in Chile, where it occurs in moist microhabitats as
. It occurs in
far north as Santiago and Valparaiso, and then
southward to the subantarctic scrub forests of Tier-
ra del Fuego. Throughout its range, F. magellan-
ica occurs as low as sea level, but only at its
northernmost range does it reach its upper alti-
tudinal limit of 1,750 m. Seasonality increases
southwards, so that in Tierra del Fuego, flowering
is restricted to the summer months of December
to March, and plants are strongly deciduous in the
freezing winter months.
e other sie species of the section all occur
in the highlands of southeastern Brazil. A single
species, F. regia, is widespread and covers the
entire range of the section in Brazil, from 18?20'S
to 29930'S. The remaining species have much more
restricted distributions, several occurring on a sin-
gle mountain range.
Fuchsia regia consists of three largely allopatric
subspecies Subspe ec ies
mainly in dense
dawa forests at the crests and on the seaward-
facing escarpments of the coastal mountains from
Rio Grande do Sul to northern São Paulo state, at
elevations of 500-1,450 m. In Santa Catarina,
however, it is also found in enclaves of montane
vegetation on the summits of the isolated *morros"
that emerge just 100 to 300 m above the Atlantic
lowland forest in the Itajai Valley (Klein, 1978).
It has also been found at sea level in restinga forests
near the Santa Catarina- Rio Grande do Sul border,

where Reitz (1961) found a number of other plants
typical of the high inland serras.
Fuchsia regia subsp. reitzii is restricted to
thickets and low forest on the drier planalto, or
southern highlands, that occupies much of the in-
terior of Paraná, Santa Catarina, and Rio Grande
do He It occurs at altitudes between 900 and
m in areas subject to strong winter frosts
ed 1984). The range of subsp. reitzii in this
area coincides quite closely with Araucaria an-
gustifolia, the dominant element of the planalto
forests (Hueck, 1953). In Rio Grande do Sul and
southern Santa Catarina, the joris ends abruptly
to the east at the **Aparados” or ** ' sheer
cliffs that drop down beh of meters to the
Atlantic coastal plains. At these sites, subsp. reitzii
reaches its eastern limit, growing sympatrically
along a narrow band with the westernmost popu-
aimbes,'
lations of subsp. serrae.
Fuchsia regia subsp. regia occurs further north
in a series of separate mountain systems, from
northern Sào Paulo to Rio de Janeiro, Minas Gerais,
and Espirito Santo. It grows in cloud forests be-
ginning at 1,000 m and reaches open campos
above treeline as high as 2,400 m on Mt. Itatiaia.
Several species are restricted to high altitudes
and are known from just one area. Fuchsia bra-
celinae grows only between 2,300 and 2,850 m,
above treeline in the “campos de altitude" of a
few peaks of the Serra do Caparaó. This is the
highest mountain range of southern Brazil, situated
along the Minas Gerais- Espirito Santo border. Sim-
ilarly, F. campos-portoi occurs only in campos
around Mt. Itatiaia, in the Serra da Mantiqueira,
between 2,100 and 2,550 m. Fuchsia coccinea
occurs naturally only at the summit of four of the
highest mountains in Minas Gerais, between 1,400
and 2,000 m
Two species are endemic to several of the high,
granitic *morros" characteristic of the Serra do
Mar in Rio de Janeiro state. Fuchsia alpestris
grows among bushes at the base of granitic outcrops
in the Serra dos Órgãos and around Santa Maria
Madalena. Fuchsia glazioviana is found as high
as 2,100 m in open campo vegetation on morros
around Nova Friburgo and Santa Maria Madalena.
It also descends into e forest as low as 1,500
m on the same mountai
Two newly described pcm from Paraná and
southern Sáo Paulo states have broader ranges.
Fuchsia brevilobis occurs in forests of low, inland
mountain ranges at 600—900 m, but on the eastern
slopes of the Serra do Mar in Paraná, it is found
from 400 m to sea level. Fuchsia hatschbachii
occurs further inland in Paraná, in drier forests
than the coastal mountains, and is apparently re-
stricted to limestone and sandstone outcrops be-
tween 950 and 1,150 m.
REPRODUCTIVE BIOLOGY
The members of sect. Quelusia all conform to
a very similar pattern of floral biology. The flowers
are hermaphroditic and self-compatible, as well as
protogynous and herkogamous. Consequently, the
enus has been characterized as
crossing" (Raven,
pendent, with the stigma exserted well below the
anthers, a prime example of “approach herkoga-
my” (Webb €: Lloyd, 1986), where the stigma is
contacted as the visitor enters the flower prior to
picking up pollen. Protogyny is incomplete, how-
ever, because the anthers begin to dehisce within
a day after anthesis, while the stigmas remain re-
ceptive from the onset of anthesis until flower se-
nescence several days later. Despite the presence
of these outcrossing mechanisms, geitonogamous
pollen transfer may still lead to effective selfing.
Automatic selfing can also occur, since pollen usu-
ally hangs down in clumps joined by viscin threads,
which are able to contact the stigmatic surface
before the flower senesces.
The flowers of sect. Quelusia are highly spe-
cialized for pollination by hummingbirds. Each
species has red, odorless, hanging, tubular flowers
with copious nectar secreted at the base of the
floral tube, all standard features in hummingbird-
pollinated plants (Faegri & van der Pijl, 1979).
Unlike other bird-pollinated fuchsias, however, the
petals are much larger and strongly convolute; they
thus act functionally as a prolongation of the floral
tube, further restricting the access of insects to the
nectary. eep blue-violet color of the petals
of sect. Quelusia is unique in the genus, althoug
its significance in pollination is not clearly under-
stood. The abundance of viscin threads in Fuchsia
is among the most copious in the family and has
been considered a probable adaptation to bird pol-
lination (Nowicke et al., 1984)
Hummingbirds are commonly observed visiting
the flowers of sect. Quelusia throughout its native
range, but few published accounts have identified
the species of the hummingbird visitors. Curtis
(1836) cited an early account by J. Anderson, the
botanist on Philip King's voyage to the Magellan
Straits, who observed numerous hummingbirds vis-
iting F. magellanica around Port Famine, even
after days of constant rain and sleet at near-freez-
ing temperatures. Hauman-Merck (1912) reported
frequent visits of Eustephanus galeritus (Mol.) on

F. magellanica near Corral, in Valdivia, Chile. In
Brazil, Ruschi (1982) reported Colibri serrirostris
(Vieillot) visiting flowers of F. regia. A Plovercrest
hummingbird, Stephanoxis lalandi (Vieillot), was
observed visiting Fuchsia in the open campos area
of Mt. Itatiaia, Rio de Janeiro state by Mitchell
(1957), as well as by Ruschi (1982) in Teresopolis
at 900 m. Three hummingbird species, Colibri
serrirostris, j euco-
chloris albicollis, were common around F. bra-
celinae in the Serra do Caparaó, at 2,400 m,
during a visit in February 1985 (L. Gonzaga, pers.
comm.). It is unlikely that any strong pollinator
discrimination exists between the different species
) flowers are very
Stephanoxis lalandi, and
of Fuchsia in Brazil, since the
similar in size and overall floral pattern. On both
F. campos-portoi and F. brevilobis, I have seen
two different hummingbird species visiting flowers
of the same bush in rapid succession, and I also
watched an individual hummingbird visit flowers of
F. brevilobis right after leaving flowers of a neigh-
boring plant of F. regia subsp. serrae.
Besides hummingbirds, several insect species
have also been observed visiting flowers of sect.
Quelusia in their native habitat. Apis mellifera
was a common visitor to flowers of F. coccinea at
Serra da Piedade, Minas Gerais, during our visit
in February 1985; it was also observed on
campos-portoi at Mt. Itatiaia in January 1985.
Hauman-Merck (1912) described the visits of
bus chilensis to F. magellanica in southern
Chile, and thought it to be a more important visitor
there than hummingbirds. Both of these bee species
hang from the anthers to collect pollen and ma
attempt to reach the nectary at the base of the
tube; Bombus, especially, is able to make contact
with the stigma and acts as an effective pollinator.
I also saw a butterfly visiting F. regia subsp. serrae
near Mogi das Cruzes, Sào Paulo, Brazil; it grasped
the stamens attempting to enter the floral tube for
nectar and made contact with both the anthers and
the stigma in the process. When species of sect.
Quelusia are cultivated outside their native range
in areas where hummingbirds do not occur, such
as England, they are frequently visited by honey
bees and bumblebees (J. Wright, pers. comm.).
Seed dispersal is probably effected by frugivo-
rous birds, although no direct observations or pub-
lished reports have been made.
MORPHOLOGY
Habit and stems. Plants of sect. Quelusia are
all shrubs or lianas. Stems are usually flexuous and
require the support of neighboring vegetation, but
low, densely branched shrubs are common in such
species as F. coccinea and F. bracelinae. Fuchsia
regia can become a large, forest liana, with stems
to 20 cm in diameter climbing as high as 15 m
into the tree canopy, but it can also be found
growing as a compact shrub in open situations. On
large, climbing plants of F. regia and F. alpestris,
it is common to find hanging branches several
meters long. Short, divaricating side shoots are
typical of young plants of F. regia subsp. serrae.
Vegetative reproduction occurs in most taxa
through stem-layering, especially when long, flex-
uous stems lay over ground litter. Fuchsia bra-
celinae and F. coccinea reproduce locally by un-
derground, stoloniferous stems, and some
populations of F. regia subsp. serrae ]
roots on shoots well above the ground, as described
by Lindley (1841) for F. radicans.

posite or whorled. The most corumon condition in
the section is ternate leaves, but individual plants
often combine leaves in pairs, threes, and fours on
different shoots. Exceptions are F. alpestris, almost
always with opposite leaves, and F. regia subsp.
reitzii, with leaves all in whorls of 3, 4, or 5.
Fuchsia glazioviana has unusually short inter-
nodes, just 3-12 mm long, with the leaves densely
packed on the stems.
The texture of the leaves of most species is
membranous, but F. regia subsp. serrae has co-
riaceous leaves, and those of F. regia subsp. regia
are mostly subcoriaceous. Leaf surface is a useful
character in some taxa; it is smooth and lustrous
in F. regia subsp. serrae, with a dark green color
above and a paler tone below. Leaf surfaces of
Fuchsia glazioviana and F. hatschbachii are sim-
ilar, but the surface is less brilliant. Impressed leaf
veins are especially characteristic of F. bracelinae,
and to a lesser M dii in F. brevilobis. Secondary
venation in leaves of F. campos-portoi can be
almost ds while in F. regia subsp. re-
itzii a conspicuous tertiary venation is usually ev-
ident.
Leaf size and shape vary considerably within
taxa, but some differences can be readily distin-
guished. The leaves of Fuchsia glazioviana, F.
bracelinae, and F. campos-portoi are small, most-
y less than 4 cm long, and very narrow in F.
campos-portoi. 'The largest leaves occur in F. al-
pestris and F. regia subsp. regia and are mostly
6-14 cm long. Ovate leaves with cordate bases
are diagnostic of F. coc

subsp. reitzii they are conspicuously gland-serru-
late, with the teeth angled towards the leaf apex.
Fuchsia magellanica has mostly serrulate mar-
gins, but they are sometimes crenate, with shallow
lobes between the teeth.
Petiole length is useful in discriminating taxa in
sect. Quelusia. Fuchsia coccinea and F. brace-
linae have nearly sessile leaves, with petioles 1—3
mm long, while they exceed 10 mm in F. regia
subsp. regia and F. regia subsp. serrae. Often the
proportion of the petiole to the blade length is very
informative: high (> 1:4) in F. regia and F. mag-
ellanica, and low (1:8 «) in F. hatschbachii and
F. alpestris. Petioles are stout and over 1 mm
thick in F. alpestris, F. coccinea, F. regia subsp.
serrae, and F. regia subsp. regia; they are slender
in F. magellanica.
Stipules in all but one taxon are small, lanceo-
late, and deciduous. Fuchsia regia subsp. serrae
is unique, with prominent, persistent stipules that
are thick and recurved, usually fused in pairs be-
tween adjacent leaves, and give a characteristic
nodose appearance to the stems.
Flowers.
in pairs in the axils of young leaves near the branch
Flowers are all borne singly or rarely
tips. Rarely more than two or three whorls of leaves
bear flowers at the same time on a single stem.
The pedicels are pendulous, except in F. coccinea,
where they are divergent from the stem before
hanging down in the distal half.
Section Quelusia is the only group in the genus
where the sepals are much longer than the floral
tube. In addition, the sepals are always connate to
varying degrees at their base, which in effect
lengthens the tubular portion of the flower. The
petals are strongly convolute and form a cone
around the stamens and stigma. The nectary con-
sists of a smooth to slightly lobed band ca. 1 mm
thick lining the inner, basal portion of the floral
tube. A flower from sect. Quelusia is illustrated
diagrammatically in Figure 2.
The floral tubes of most species are cylindrical-
fusiform, but F. campos-portoi is distinct with its
short, subrhombic tubes. Sepal connation is only
-6 mm in most taxa. Fuchsia brevilobis is ex-
ceptional, with sepals connate for 10-16 mm, al-
most completely concealing the corolla and longer
than either the free sepal lobes or the true floral
tube. Fuchsia regia subsp. serrae also has sepals
joined for over 4 their length; the buds are no-
ticeably four-ridged, and the free lobes sometimes
recurve after anthesis.
Fruits. Berries in sect. Quelusia are generally
oblong-ellipsoid and dark purple to black when ripe.
n F. regia subsp. reitzii, the berries are mostly
globose, while in F. magellanica they are much
more elongate than in the other species. Ovules
are biseriate in each locule and number between
60 and 120 per fruit.
CYTOLOGY AND PALYNOLOGY
Cytology. Concurrently with this revision,
Hoshino & Berry (1989) made an extensive cy-
tological survey of all 11 taxa of sect. Quelusia,
examining 103 individuals from natural popula-
tions and 11 cultivated plants. Their results showed
the section to be entirely polyploid, predominantly
tetraploid (n — 2x — ; i
= 4x = 44) found in two species. All other sections
in the genus, except for the tetraploid, monotypic
sect. Kierschlegeria, are entirely or mostly diploid
(n=x= 11).
Tetraploidy was found in all specimens examined
ut with octoploidy (n
of six Brazilian species and in the more than 40
populations that were studied from the widespread
F. magellanica of the southern Andes (see Hoshino
& Berry, 1989, Table 1). Normal bivalent for-
mation was observed in all of these collections.
Octoploidy was limited to the three subspecies
of F. regia and a single cultivated individual of F.
alpestris. Fuchsia regia subsp. reitzii and F. regia
subsp. serrae were consistently octoploid, but tet-
raploid individuals were also found in F. alpestris
and F. regia subsp. regia. In all octoploids ex-
amined, varying numbers of quadrivalents were
present at meiotic Metaphase I and Anaphase I.
Although tetraploid and octoploid plants occurred
sympatrically in several localities, no hexaploid in-
dividuals were detected. The chromosome numbers
of the individuals examined by Hoshino & Berry
are indicated in this paper under the specimen
citations of the respective taxa.
Palynology. Pollen grains of Fuchsia have
distinctive, onagraceous features such as viscin
threads, paracrystalin e-spongy ektexine, protrud-
ing apertures, and a solid endexine. The genus is
unique, however, in possessing predominantly two-
aperturate, bilaterally symmetrical pollen grains.
Radially symmetrical, three-aperturate grains also
occur in the genus but are confined to polyploid
species and are clearly derived from two-aperturate
ancestors, a result of the increased cell volume of
polyploid cells. Most sections of the genus can be
distinguished by a combination of aperture number,
viscin thread ultrastructure, and t
sculpture elements. Detailed pollen descriptions of
the different sections are provided in Praglowski
et al. (1983) and Nowicke et al. (1984)
e of exine

Annals of the
Missouri Botanical Garden
The members of sect. Quelusia have radially
symmetrical and three-aperturate pollen grains, a
condition consistent with the polyploidy found in
all species of the section. Viscin threads are seg-
mented-beaded, and the exine has globular sculp-
ture elements. Praglowski et al. (1983) reported a
size range of 33-60 um for P (polar axis length)
and 59-85 um for E (equatorial axis) for the seven
taxa they examined. Rare four-aperturate grains
have been found in F. coccinea and F. regia;
occasional two-aperturate grains were also found
in F. magellanica and were considered to be re-
versions to the ancestral condition of the genus
(Praglowski et al., 1983; Nowicke et al., 1984).
Octoploid individuals of F. regia cannot be distin-
guished from tetraploids by differences in pollen
morphology, although octoploid pollen grains may
be significantly larger (Hoshino, pers. comm.).
he only other section of Fuchsia characterized
by three-aperturate pollen is the monotypic sect.
Kierschlegeria (F. lycioides). Its pollen can be
distinguished from that of sect. Quelusia, however,
by the smooth viscin threads with elongated sculp-
ture elements (Nowicke et al., 1984).
FLAVONOID COMPOUNDS
Because of the ornamental appeal of Fuchsia,
several studies have examined the role of antho-
cyanins in the different flower colors in the genus
(Harborne, 1963; Yazaki & Hayashi, 1967; Noz-
zolillo, 1970; Yazaki, 1976; Crowden et al., 1977).
Flower colors are determined almost entirely by
the 3-glucosides and 3,5-diglucosides of all six com-
mon anthocyanins. Red coloration in the sepals
and floral tube is due mostly to cyanidin and peon-
idin pigments, whereas the characteristic blue-vi-
olet color of the petals of all members of sect.
Quelusia is due to the dominance of malvidin de-
rivatives, with peonidin in much lesser concentra-
tions (Nozzolillo, 1970; Yazaki, 1976; Crowden et
al., 1977). Yazaki (1976) indicated that the intense
blue-violet color of some cultivars is due to the
simultaneous presence of other co-pigments in the
cell, particularly quercetin glycosides. In some cul-
tivars, the petals change color from blue-violet to
purple-red with age; Yazaki (1976) has shown this
to be due to the combined effect of the flavonoid
co-pigments, together with a decrease in the pH
of the cell sap brought about by the accumulation
of organic acids.
Averett et al. (1986) carried out a comprehen-
sive survey of the foliar flavonoids in 80 taxa of
Fuchsia and reported the flavonoid profiles of four
taxa belonging to sect. Quelusia. Current taxo-
nomic changes in the section, however, have mod-

ified these results, and a revision is presented in
Table 1. Based on the same samples examined by
Averett et al. (1986), two additional taxa are now
included, F. brevilobis and F. regia subsp. serrae.
From these changes, it is apparent that it is F.
brevilobis, not F. regia, that has a distinctive fla-
vonol diglucoside. Fuchsia magellanica remains
the only species in the section known to possess
flavones (compounds 12 and 15), which could be
used as excellent markers for detection of the par-
entage of this species in cultivars of uncertain or-
igin, although flavones might not be expressed in
all F. magellanica hybrids. Otherwise, the re-
maining flavonol monoglucosides are all of common
occurrence in other taxa of the genus.
NATURAL HYBRIDIZATION
Because of the restricted distributions of most
of the Brazilian species of Fuchsia, there is no
range overlap among them, except with the wide-
spread F. regia. Fuchsia regia occurs sympatri-
cally with five other species, and in eac
morphologically intermediate, putatively hybrid in-
dividuals have been detected (Table 2). Populations
of F. regia subsp. serrae also occur together with
each of the other subspecies of F. regia, forming
extensive hybrid swarms in areas of sympatry.

The ee orae dta intermediacy of several char-
acters was the main criterion used in detecting
hybrids iind different taxa; in most cases, both
putative parents were growing sympatrically close

Natural hybridization among sympatric taxa of
sect. Quelusia appears to occur readily, as there

indication that reduced fertility might occur in hy-
brids was from one artificial cross between a tet-
raploid individual of F. regia subsp. regia and an
octoploid individual of F. regia subsp. serrae, where
the hexaploid progeny showed low pollen fertility
(Hoshino & Berry, 1989). More experimental work
is needed on the chromosomal behavior of crosses
between tetraploid and octoploid taxa in sect. Que-
lusia.
In most cases, the area where two species over-
lap is small, and the frequency or abundance of
hybrids is low compared with the parental popu-
lations. Fuchsia campos-portoi, F. coccinea, and
F. glazioviana are all high-altitude species that

grow in the open **campos de altitude" at or above
treeline. Hybrids between these species and F. re-
gia occur where they descend into the upper forest
zone, or when F. regia extends beyond its normal
limit into the open campos. Fuchsia brevilobis has
the inverse of this pattern, generally occurring at
lower altitudes than F. regia subsp. serrae, with
probable hybrids in limited areas where their ranges
overlap. Fuchsia bracelinae may have grown sym-
patrically with F. regia until the past century, when
extensive cutting and burning eliminated the upper
forest belt of most of the Serra do Caparaó.
The situation among the subspecies of F. regia
is notably different. These taxa are much more
widespread and overlap more extensively than any
of the other species in the section. Fuchsia regia
subsp. reitzii is typical of the planalto region in
Rio Grande do Sul and southern Santa Catarina
states, but it contacts populations of the more mesic
F. regia subsp. serrae along the easternmost edge
of the planalto near the crests of the Serra Geral,
producing large, widely variable, intermediate pop-
ulations. Extensive intergradation between F. regia
subsp. regia and F. regia subsp. serrae occurs

Although F. regia is the only species presently
found in widespread contact with other species of
sect. Quelusia, the numerous hybrid combinations
detected indicate that interspecific genetic recom-
bination may have been an important mechanism
in providing a rich source of novel, adaptive ge-
notypes in the fuchsias of southern Brazil.
EVOLUTION OF SECTION QUELUSIA
Various lines of evidence, including chloroplast
DNA restriction fragment analysis (Sytsma & Smith,
1988) and leaf flavonoid analyses (Averett et al.,
1986), have suggested the Old World sect. Skin-
nera to be the earliest offshoot of the genus and
the sister group of all the American sections of
Fuchsia. The oldest fossil pollen grains of the genus
have been found in New Zealand and Australia
from Oligocene and Miocene deposits (Pocknall &
Mildenhall, 1984; Berry et al., in prep.). Despite
the early divergence of this group, the members
of sect. Skinnera exhibit several specialized fea-
tures for the genus, including the derived condition
of male sterility, reduced petals, presence of flavone
sulphates, and a variety of unusual life forms, such
as large trees and procumbent creepers.
The most likely area of origin of Fuchsia is
South America, where the greatest concentration
of species as well as the sections with the most
generalized features in the genus occur (Raven,
1979a; Berry, 1982). Whereas the large Andean
sections appear to have arisen and radiated during
the Neogene uplift of the tropical Andes (Berry,
1982, upied by sect.
Quelusia have changed little since the mid-Ter-
tiary, when temperate forests were much more
widespread in southern South America (Simpson,
1973). With the current Australasian fossil record,
it is now apparent that Fuchsia formed part of the
5) the areas now occ
Nothofagus and podocarp-dominated temperate
forests that occurred more or less continuously
across southern South America, Antarctica, and
Australia until at least the late Eocene (Zinmeister,
1987; Truswell, in press). The wet, temperate for-
ests of the southern Andes and the montane forests
of southeastern Brazil are now the only remnants
of these austral temperate forests in South Amer-
ica, which, like Fuchsia, share a large number of
disjunct plant groups that also have close relatives
in Australasia (Raven, 1979b)
Although there are no fossil records to indicate
an early presence of sect. Quelusia in South Amer-
ica, the section follows a pattern consistent with
other relicts of the southern temperate forests. It
is ecologically conservative, with most individuals
restricted to moist sites in cool, forest habitats.
Morphologically, there is little divergence in the
section, with species differentiated by relatively
minor variations on a common pattern of floral and
vegetative characters. Many of the features of sect.
Quelusia are unspecialized in the genus, including
the axillary, bisexual flowers, well-developed petals,
numerous seeds,
threads. It is possible that some of the primitive
characters in sect. Quelusia were preserved throug
and segmented-beaded viscin
the buffering effects on evolutionary divergence
caused by paleopolyploidy in the group (Stebbins,
1985; Hoshino & Berry, 1989)
The ancestor of the modern-day species of sect.
Quelusia was probably tetraploid, with derived,
three-porate pollen (Hoshino & Berry, 1989). As
such, it could not have given rise directly to the
other, mostly diploid, sections of the genus, but
rather represents an early offshoot of the ancestral
stock of Fuchsia in South America. Early on, sect.
Quelusia developed its own floral syndrome for
hummingbird pollination: the relatively short, nec-
tar-holding floral tube; large, attractive sepals; and
petal cone and sepal tube that further extend the
tubular portion of the blossom.
Section Kierschlegeria, containing only F. ly-
cioides restricted to the dry coastal scrub of central
Chile, is the only other section of Fuchsia that is
entirely polyploid and has three-porate pollen grains.
Because of this similarity and its geographic prox-
imity to F. magellanica, Berry (1982) and Raven
1988) postulated that it is related to sect. Que-
lusia. Using chloroplast DNA restriction fragment
analysis, Sytsma & Smith (1988) demonstrated
that sects. Quelusia and Kierschlegeria form a
distinct lineage from the rest of the genus, defined
by three synapomorphies. Furthermore, within this
—
lineage F. lycioides could not be distinguished from
the two species of sect. Quelusia studied, F. ma-
gellanica and F. regia. This evidence of a close
relationship is remarkable, since F. lycioides has
a high number of specialized features, such as
functional dioecy, spinose leaf bases, low seed num-
ber, smooth viscin threads, small flowers, and sum-
mer deciduousness. Evidently, the evolutionary shift
of sect. Kierschlegeria to a xeric habitat in the
southern Andes entailed a large number of mor-
phological changes corresponding to a much small-
er degree of genotypic divergence.
Within sect. Quelusia, we are faced with the
question of why there is just one species in Chile
and Argentina, while in Brazil there are eight species
Volume 76, Number 2

Fuchsia sect. Quelusia
in an area of comparable size. Fuchsia magellan-
ica is a classic example of the lack of differentiation
that is characteristic of the /Vothofagus forests of
Chile. These habitats presumably have been stable
and continuous for long periods of time, providing
little opportunity for speciation to occur. Most taxa
inhabiting these areas have retained primitive char-
acters for their respective groups (Simpson, 1973).
Although the current distribution of F. magellan-
ica extends beyond the Nothofagus forests, vir-
tually all of the area now occupied by this species
south of 44°S latitude was covered by ice during
the Pleistocene (Vuilleumier, 1971)
In contrast to the temperate latitudes of Chile
and Argentina, the Brazilian members of sect. Que-
lusia are centered in the subtropics. There, Fuch-
sia is limited to the cool, moist habitats of the
oastal mountains and the interior planaltos. Most
of the cold-adapted taxa of Brazilian fuchsias are
vicariant species that are now restricted to just a
few high mountain peaks. Allopatric speciation in
this group of species was likely enhanced by the
joining and subsequent separation of populations
caused by the cycles of Pleistocene glacial and
interglacial events (Simpson, 1979; Klein, 1984).
Two of the Brazilian species have adapted to
warmer, lower-altitude habitats that are more con-
tinuous over much of the southeastern part of the
country. Fuchsia regia extends over the entire
range of the section in Brazil and forms a broad
taxonomic complex treated here as comprising three
subspecies, each adapted to a slightly different set
of environmental conditions. This species shows an
intermediate stage in the morphological differen-
tiation of populations between the more uniform
F. magellanica in the southern Andes and the
distinct, high-altitude species of Brazil. Fuchsia
regia overlaps geographically with most of the
other species in the section and hybridizes with
them whenever they come into contact; these hy-
brids may constitute an important source of genetic
recombination for new adaptive genotypes in the
section. It is also the only species in the genus with
naturally occurring octoploid populations, which
may lead to partial reproductive isolation with the
other tetraploid taxa in the section.
Two newly described species from Paraná, Brazil
both consist of tetraploid populations that occur
within the range of the octoploid subspecies of F.
regia. The different ploidy levels may afford suf-
ficient reproductive isolation for these species to
remain distinct. One of the new species, Fuchsia
hatschbachii, 1s the only species in the section that
appears to be edaphically specialized, occurring on
limestone and sandstone substrates on the eastern
edge of the southern planalto. Populations of F.
regia subsp. serrae occur within m of F.
hatschbachii near Curitiba, Paraná, but the two
have never been observed to grow together under
natural conditions. The other new species, Fuchsia
brevilobis, is specialized in its small flowers with
elongate sepal tubes, and it has become adapted
to lower altitudes than most neighboring popula-
tions of F. regia.
Overall, the evolutionary scenario of sect. Que-
lusia differs significantly from the two, more spe-
ciose, Andean sects. Fuchsia and Hemsleyella.
Those species radiated recently into a broad ex-
anse of new, cool montane habitats that were
created with the recent uplift of the tropical Andes
(Berry, 1982, 1985). Section Quelusia, on the
other hand, has occupied a more ancient and stable
vegetation type in which disruptive selection may
have played less of a role in the divergence of
populations.
CLADISTIC ANALYSIS
This section examines the relationships of the
taxa of sect. Quelusia and the closely related F.
lycioides by means of a formal cladistic analysis.
The advantages of this approach are that it provides
clearly stated hypotheses about evolutionary re-
lationships based on shared, derived character
states, and it is based on an objective, repeatable
methodology.

crocomputer by the Wagner parsimony method of

ford, 1985), using the branch and bound algorithm

determined by outgroup comparison (Hennig, 1966;

lycioides is the sister group to all of sect. Quelusia.
Section Quelusia is well delimited by the presence
of four synapomorphies, and F. lycioides possesses
eight unique, derived character states (autapo-
morphies). Within sect. Quelusia, F. magellanica
appears as the sister group of all the Brazilian taxa,
which are grouped by a single character, loss of
flavones. The Brazilian taxa of Fuchsia are poorly
differentiated by the cladistic analysis, forming a
polychotomy with four different lineages. Fuchsia
hatschbachii is an isolated line in Brazil, differing
from F. magellanica only by the loss of flavones.
The three subspecies of F. regia form a separate,
mainly octoploid lineage, supporting the monophy-

ly of F. regia sensu lato. Fuchsia glazioviana and
. campos-portoi are sister species within the third
lineage. The fourth lineage includes four species,
which are divided into two species pairs, the high-
altitude F. bracelinae and F. coccinea, and F.
alpestris and F. brevilobis. Two homoplasies (par-
allelisms) occur in the cladogram: long-connate se-
pals in F. brevilobis and F. regia subsp. serrae,
and lianoid habit in two species pairs.
The paucity of characters that discriminate be-
tween the taxa of sect. Quelusia makes the results
of the cladistic analysis within the section quite
tentative, but it is also a reflection of the very close
relationship of the species. The proposed sister-

group relationship of F. magellanica to the Bra-
zilian members of the section is consistent with the
biogeography of the group and the evolutionary
hypotheses discussed previously, specifically the
southern origin of the genus in South America and
the secondary radiation of the section in the high-
lands of southeastern Brazil. According to this hy-
pothesis, the Brazilian taxa differentiated, after their
separation from the Andean F. magellanica, from
an ancestor that had lost flavones. The occurrence
of two parallelisms between F. brevilobis and F.
regia subsp. serrae is remarkable and may be the
result of past hybridization between the two species.
HisTORY OF CULTIVATION
Members of sect. Quelusia were by far the most
important species used in the early stages of fuchsia
breeding. For the most part, however, fuchsia
breeders in the past century kept few records about
the parentage of their introductions. As a result,
it is impossible to determine with certainty which
species have been involved in the parentage of
most of the modern cultivars (Reiter, 1944). An-
cestry of sect. Quelusia can be assumed in cultivars
that share the following exclusive **quelusioid" traits:
fairly large, axillary flowers with sepals equal to or
longer than the floral tube, and large, violet, round-
ed, and strongly convolute petals.
Following Reiter (1944), one can distinguish
three stages in the history of fuchsia breeding dur-
ing the past century. First, a variety of species and
natural varieties were accumulated in cultivation.
different introductions from sect. Quelusia, and
then in a more important step, these were crossed
with Mexican and Central American species of sect.
Ellobium. Some of the resulting strains were fur-
ther crossed with species of other sections, such
as F. boliviana (sect. Fuchsia) and F. lycioides
(sect. Kierschlegeria). Although some other cross-
than the quelusioid crosses. The final stage involved
the exploitation and selection of mutations, which
no longer depended upon the introduction of native
material. In the remainder of this section, I will
review the role of sect. Quelusia in the first two
stages of fuchsia breeding, then summarize the
present-day situation of sect. Quelusia species in
cultivation.
Species introductions. With the possible ex-
ception of a short-lived introduction of F. triphylla
in the early 18th century (Wright, 1975), F. coc-
cinea was the first species of Fuchsia introduced
into cultivation in Europe. Plants of this species
were growing at Kew Gardens in London in 1788
(Aiton, 1789), and an illustration of it was published
by Sims (1789). Hooker (1869) suggested that
Sims’s figure might have represented F. magel-
lanica rather than F. coccinea, because of the
prominent petioles on the lower leaves. This is
clearly not the case, however, as the figure ac-
curately represents the unique arching pedicels and
ovate, subsessile upper leaves of F. coccinea, and
Sims's own specimen deposited at Kew is F. c
cinea (pers. obs.). Although Dryander stated med
the plants he described were introduced from Chile
(Aiton, 1789), the species is native to just a few
mountains in Minas Gerais, Brazil.
The next introduction from sect. Quelusia was
F. magellanica. An array of different variants of
this species appeared in England in the 1820s
544
Annals of the
Missouri Botanical Garden
under several names, starting with F. gracilis,
which was reported from the Edinburgh Botanic
Garden in 1822 (Lindley, 1824). Fuchsia conica
and F. gracilis var. multiflora were both intro-
duced into England from Chile in 1824 (Lindley,
1827a, b). Fuchsia discolor was introduced from
Port Famine in the Magellan Straits around 1830
(Lindley, 1835). I have seen no other evidence,
such as old herbarium specimens from cultivated
individuals, to indicate that F. magellanica was
present in Europe prior to 1822. Soon after F.
magellanica was introduced, however, it was con-
fused with F.
coccinea (see de Candolle,
1869
Fuchsia regia was first grown in England be-
tween 1838 and 1840, under the name F. radi-
cans (Lindley, 1841), and Fuchsia alpestris was
cultivated in the Glasgow Botanic Garden as early
as 1842 (Gardner, 1843).

Interspecific crosses. Interspecific hybridiza-
tion among members of sect. Quelusia must have
begun in the mid-1820s, but the first evidence for
this was the appearance of F. globosa in a Hor-
ticultural Society exposition in London in 1832
(Lindley, 1833). Although the origin and parentage
of this plant were not known to Lindley, the illus-
tration and the description strongly suggest that it
was a cross between F. magellanica and F. coc-
cinea. A great proliferation of names of cultivars
that were either variants of F. magellanica or
crosses with F. coccinea followed in the next de-
cades, including F. riccartonii, F. tenella, F. re-
The history of these

determine their precise parentage, and names such
as riccartonii have been applied to quite different
cultivated strains (J. Wright, pers. comm.
A major step in the search for novel, interesting
traits in Fuchsia cultivars was the use of F. fulgens,
a diploid species of the Central American section
Ellobium, in crosses with selections from sect. Que-
lusia. One of the first such hybrids produced was
exhibited in London in 1839, a cross of F. fulgens
with F. globosa called “Standish's Fuchsia” (Lind-
ley, 1840), which must have been either triploid
or a spontaneously doubled hexaploid. Harrison
(1841) also made a large number of crosses of F.
fulgens with sect. Quelusia hybrids, publishing fig-
ures of the flowers of several of the different hybrids
he selected. A hybrid between F. cordifolia (— F
splendens, sect. Ellobium) and F. globosa was
grown in 1842, under the name F. exoniensis
(Paxton, 1843). Fuchsia regia was also used in a
series of crosses starting in 1840, leading to the
development of darker petal color and improve-
ment of flower shape (Wright, 1979). Fuchsia
boliviana, a member of sect. Fuchsia from South
America, may also have been used in the early
crosses with selections of sect. Quelusia (J. Wright,
pers. comm. ).
he 19th-century crosses between members of
sect. Quelusia and sect. Ellobium can be consid-
ered the "mainstream" fuchsias later treated col-
lectively under the names F. hybrida Hort. (Siebert
& Voss, 1896; Munz, 1943) and F. speciosa Hort.
(Bailey, 1900). In the strictest sense, these names
have been attributed to crosses between F. mag-
ellanica and F. fulgens. At the other extreme,
they have been used to include almost all garden
fuchsias. Reiter (1944) suggested that F. hybrida
might best be treated as a horticultural complex
including all cultivars of sects. Quelusia x Ellob-
ium ancestry, including many of complicated ori-
Chaudhuri (1956) made cytological observations
that suggest how crosses between F. magellanica
and F. fulgens might have facilitated the rapid
advances in fuchsia breeding during the mid-1 800s.
In his crossing experiments, the tetraploid (n — 2x
— 22) F. magellanica and the diploid (n — x —
11) F. fulgens yielded triploid progeny in which a
high percentage of unreduced gametes were pro-
duced. As a result, the F, crosses were partially
fertile, and hexaploids (6x) were produced in the
F, generation, as well as tetraploid (4x) and pen-
taploid (5x) individuals in the respective backcross-
es. All of these crosses retained some degree of
fertility. Crosses between F. magellanica and other
diploids, such as F. splendens and F. denticulata,
did not have the same propensity for unreduced
gametes as F. fulgens, and their hybrids were large-
ly sterile. Thus, F. fulgens may have been a critical
species that helped prevent total sterility in crosses
with the polyploid members of sect. Quelusia and
with later cultivars of even higher ploidy levels.
O. Wright in England has
confirmed Chaudhuri's findings, producing a com-

further reports that none of these hybrids showed
any obvious similarity to F. fulgens.
Fuchsia magellanica is the only species in sect.

long periods of freezing temperatures, so that all
of the hedge plants of fuchsia grown outdoors in

Many of the recent introductions from Brazil, how-
ever, such as F. campos-portoi and F. coccinea,
are proving to be frost-resistant as well (J. Wright,
pers. comm. ).
Native species in cultivation today. Many of
the early species introductions have been main-
tained for long periods of time in cultivation without
crossing. Thus, Hooker (1869) was able to trace
plants of F. coccinea found in the Oxford Botanic
Garden in 1867 back to the original introduction
of that species at Kew in 1788. Although this
species may have been later lost from cultivation
in England and Europe, it was successfully estab-
lished on several of the Atlantic islands off the
north African coast, such as Madeira, St. Helena,
and the Canary Islands, in the early 1800s, per-
sisting to present day (Hansen, 1969; A. Calero,
pers. comm.). Plants of F. alpestris grown today
in England and continental Europe have particu-
larly small leaves similar to Gardner's type speci-
men and may well date back to his original intro-
duction in 1842. Wild strains of F. magellanica
are apparently still present in England, and the
species has become widely naturalized in parts of
Ireland, New Zealand, Hawaii, South America, and
eastern and southern Africa.
As a result of the author's collections of native
fuchsias in Brazil between 1985 and 1987, and
seeds of different strains of F. magellanica ob-
tained from Chile and Argentina, many new species
and strains from sect. Quelusia have been recently
introduced into cultivation. All the taxa recognized
in this treatment, except F. bracelinae and F.
glazioviana, are now in cultivation, with the most
complete collections grown at the University of
California Botanical Gardens at Berkeley and in
the private garden of Mrs. Drude Reiman-Dietiker
in the Netherlands. Other important collections
include those of Mr. J. O. Wright in England,
members of the different amateur fuchsia societies
on the west coast of the U.S., and the Nederlandse
Kring van Fuchsia-Vrienden in the Netherlands.
SYSTEMATIC TREATMENT
Taxonomic history. The earliest known spec-
imens of Fuchsia from South America were col-
lected in the Magellan Straits around 1690 by
George Handisyd, who was surgeon aboard the
British ship Modena (Middleton, 1909). These col-
lections correspond to F. magellanica and are
deposited in the eighth volume of Hans Sloane's
herbarium at BM. Louis Feuillée published the first
description and illustration of this species under
the name Thilco (Feuillée, 1725), but it was not
taken up by Linnaeus, who described Fuchsia in
1753 in Species Plantarum. More specimens of
Fuchsia were collected in the Magellan Straits in
January of 1768 by Philibert Commerson, natu-
ralist on the French survey expedition led by Louis
de Bougainville. Commerson's specimens were ex-
amined by Lamarck, who designated them the type
collection for F. magellanica, which he described
in 1788. Another early collection of this species
was made by Ruiz and Pavón between 1778 and
1788, near Concepción, Chile; they later described
it as F. macrostema (Ruiz & Pavón, 1 ]
Domingo Vandelli published the genus Quelusia
in 1788, based on Brazilian plants. He did not
name a species, and his description and illustration
dealt mostly with the flower, making it difficult to
distinguish which of the Brazilian species he was
treating. José M. da C. Vellozo, a contemporary
of Vandelli, described Quelusia regia from Brazil,
providing locality information and an illustration
that included leaves and flowers. Due to political
problems, however, Vellozo's name for the species
was not published until 1829 (Borgmeier, 1937;
Carauta, 1973).
Jonas Dryander described Fuchsia coccinea in
1789 based on cultivated plants that had been
introduced in England the previous year. The source
of his plants remains unclear, however, since Aiton
(1789) attributed their introduction from Chile by
a Captain Firth, while Salisbury (1791) stated that
they were brought from Brazil by Vandelli around
1787. In reprinting Vandelli's publication of Que-
lusia, Roemer (1796) added a footnote wherein
he stated that Vandelli’s genus was the same as
Dryander's F. coccinea. Meanwhile, Salisbury
(1791) had already synonymized Quelusia under
F. coccinea.
In the first conspectus of the genus, de Candolle
(1828) designated Quelusia as a section of Fuch-
sia; by that time, the identity of F. magellanica
and F. coccinea were already badly confused, and
de Candolle considered them to be synonymous.
Collections made in Brazil by Auguste de Saint-
Hilaire between 1816 and 1822 resulted in the
description of four new species by Jacques Cam-
bessédes in 1830. None of these species have been
maintained in the present treatment, but the name
F. integrifolia Camb. was long used for F. regia.
During the 1820s and 1830s, there was a sud-
den surge of collections of Fuchsia from Brazil and
Chile, and many plants were shipped for cultivation
in Europe. Several new taxa, most of them now
included under F. regia and F. magellanica, were
described by John Lindley, George Gardner, and
Karel Presl. During the second half of the 19th
546
Annals of the
Missouri Botanical Garden
century, Auguste Glaziou made extensive collec-
tions in eastern Brazil, when this area was off limits
to most foreign botanists. The rare F. glazioviana
was described from one of his finds
During the first half of this century, Curt Brade
and Ynes Mexia collected fuchsias from the two
highest peaks of southern Brazil, Pico da Bandeira
and Itatiaia. Their collections led to the description
of two local endemics, F. bracelinae and F. cam-
pos-portoi.
The leading figure in Fuchsia taxonomy was
Philip Munz, who published a comprehensive re-
vision of the genus in 1943. He refined the sectional
concepts and limited sect. Quelusia to a closely
knit group of species from Brazil and one from the
southern, temperate Andes. He recognized five
species in the section, as well as F. hybrida, which
covered most of the cultivated hybrids. Two of his
species were polytypic: F. magellanica had three
varieties, and F. regia four.
Since Munz, many new collections have accu-
mulated, especially from the southern states of
Brazil, where Balduino Rambo, Raulino Reitz, Rob-
erto Klein, and Gert Hatschbach have made sig-
nificant contributions. Their collections have led
me to recognize four new taxa of Fuchsia from
the south of Brazil in this treatment. During two
field trips in 1985 and 1987, I was able to collect
and study field populations of all the Brazilian taxa.
In distinguish-
ing species within the section, I attempted to rec-
ognize basic, morphologically definable units that
are also correlated with geographical, ecological,
or cytological discontinuities between populations.
It is assumed that these units also reflect the evo-
lutionary divergences that have taken place in the
group, but such hypotheses must be subjected to
much more rigorous testing methods before they

can be substantiated.
Subspecific rank was used when a wide-ranging
species exhibited geographically or ecologically dis-
tinct morphological variants, but these were linked
by intermediate populations along localized areas
of sympatr
Although Jiri varieties have been recog-
nized in the past for some species of Fuchsia, there
is little biological basis for recognizing varieties.
Similar pale color variants, for example, have ap-
peared independently in a series of geographically
distinct populations of F. magellanica, and they
are probably the result of a single, recessive gene
mutation (Chaudhuri, 1956). I do not consider this
kind of variation worthy of formal taxonomic rec-
ognition in a biosystematic revision such as this,
although I do recognize the utility of assigning
names to such plants for horticultural purposes.
In widespread species, such as F. regia and F.
magellanica, it has not been feasible to distinguish
the genetic basis for the many minor variants that
exist from environmentally induced variations or
inherent plasticity in the plants. Most likely, ge-
netically determined variations will best be rec-
ognized through careful observation of plants cul-
tivated under uniform growing conditions. In this
way, amateur and professional nurserymen can
make valuable contributions to our taxonomic un-
derstanding of sect. Quelusia in the future, espe-
cially if they maintain well-documented records of
as porch of their stock and the constancy
patterns of the different characters.
E view of the uncertain phylogeny of the species
of sect. Quelusia, they are listed as follows in
alphabetical order.

Munz (1943) treated Fuchsia alpestris as a
variety of F. regia, but the former can be readily
distinguished from F. regia by having large, mostly
opposite, short-petioled leaves. The older leaves
have a characteristic subcordate base, and the en-
tire plant has characteristic dense, pale pubes-
cence. The flowers are considerably smaller and
often much paler than those of the subspecies of
F. regia that occurs in the same area.
This species is rare in nature and is apparently
confined to shrubby patches bordering exposed rock
on the flanks of large, granitic domes. Fuchsia
regia subsp. regia always occurs nearby, and some
intergradation between the two species has been
found at Pedra Dubois, near Santa Maria Madalena
(see Appendix).

Fuchsia bracelinae is distinguished from other
members of the section by having dense, stiff pu-
bescence and small, narrow, verticillate leaves. It
inhabits only the rocky, open campos of the highest
peaks of southern Brazil, in the Serra do Caparao.
Individuals are found along rocks, in meadows, or
in protected shrub and bamboo patches. This area
is subject to frequent and severe winter frosts, and
F. bracelinae is found to within 60 m of the 2,897-
m-high summit of Pico da Bandeira.
winter dieback of the above-ground stems probably
accounts for the small stature of most plants, but
underground stems lead to extensive vegetative
reproduction in areas with good soil accumulation.

Fuchsia brevilobis is distinguished by its re-
markably long sepal tube, which almost entirely
encloses the petals, and by the membranous, pu-
bescent, narrowly ovate leaves. There are two dis-
tinct areas where this species occurs, with notable
morphological differences in their populations. In
the low ramifications of the Serra do Mar in north-
bescent, with especially long sepal tubes. Another
group of populations is found on the lower, eastern
flanks of the Serra do Mar in central Paraná, from
400 m to sea level. Most plants from these pop-
ulations have longer petioles than those of higher
altitude, and they vary considerably from popu-
lation to population in color (dull pink to bright
red), degree of sepal connation, and leaf shape and
texture.
Several populations of F. brevilobis occur in the
restinga or swamp forest close to sea level, a very

unusual habitat for Brazilian fuchsias. These plants
grow as lianas and are found along rivers or streams,
perhaps enabling them to withstand the heat and
high evapotranspiration of the Atlantic lowlands.
The population from Cacatu has unusually narrow,
lanceolate leaves with acuminate tips.
Throughout most of its range, this species is
sympatric with F. regia subsp. serrae. The pres-
ence of plants morphologically intermediate be-
tween the two taxa indicates that hybridization has
occurred between them (see Appendix). The pop-
ulations of F. regia subsp. serrae in northern Pa-
raná have exceptionally long sepal tubes, which
may be the result of introgression with F. brevi-
lobis.

Fuchsia campos-portoi is readily distinguished
from other fuchsias by its small and very narrow,
gland-serrulate leaves. It also has unusual, small
flowers; the floral tube is nearly rhombic and very
short, whereas the sepals are up to four times as
long and are noticeably inflated in bud.
This species inhabits the high-elevation campos
of the Itatiaia massif, where it grows in shrubby
patches or in open, rocky sites. Winter frosts are
common in this area. Populations of F. regia subsp.
regia grow together with F. campos-portoi, and
several intermediate plants have been found that
indicate the occurrence of local hybrids (see Ap-
pendix).

The type sheets of F. coccinea are the earliest
known specimens of this species, and both were
taken from the plant at Kew Gardens upon which
Dryander based his description (Hooker, 1869).
The source of the plants is unclear; both Sims and

coccinea from the Smith Herbarium at L
Dryander described the species as a native of Chile,
introduced to Kew by a Captain Firth. Salisbury
(1791), on the other hand, stated that Vandelli
introduced the species from Brazil around 1787.
Fuchsia coccinea is a rare species known from
just four of the highest mountain ranges in Minas
Gerais. It typically grows in rocky, open campo or
occasionally in forest patches. It has long been
confused in the literature with F. magellanica, but
F. coccinea is easily distinguished by its ovate,
subsessile leaves with a conspicuous tuft of long
hairs at the base of the lower surface. Its divergent
or arching pedicels also differ markedly from the
fully pendent flowers of the other species in the
section.
Fuchsia regia subsp. regia is known to occur
sympatrically with F. coccinea at the Pico do Itambé
and near the summit of the Serra do Itacolomi,

A series of intermediate variants between the two

in these areas (see Appendix).

Fuchsia glazioviana is distinguished by its small,
tightly grouped, shiny, subcoriaceous leaves with
short petioles. It is a local endemic known from
only two mountains in the Serra do Mar of Rio de
Janeiro, where it extends from upper cloud forest
into open campo above treeline. On the Morro da
Nova Caledónia, it is sympatric with F. regia subsp.
regia in cloud forest habitats, and the two species
hybridize locally (see Appendix).

Fuchsia hatschbachii is most likely to be con-
fused with F. regia but differs by having shorter
petioles, narrow leaves with somewhat curved pet-
ioles, shortly connate sepals, and small stipules. It
is tetraploid, whereas all examined populations of
F. regia from Parana are octoploid. Fuchsia
hatschbachii grows within 20 km of populations
of F. regia subsp. serrae and F. brevilobis but
occurs in drier, more interior areas of the planalto
and is unusual in its close association with limestone
or sometimes sandstone outcrops. The species is
dedicated to Gert Hatschbach, Director of the
seu Botánico Municipal de Curitiba, who has done
more than any previous botanist to collect and
study the flora of Paraná.

Fuchsia magellanica is separated from the Bra-
zilian members of section Quelusia by 1,000-1,500
(usually over 1⁄4 the length of the
dentate leaf margins, which are sometimes shal-
lowly lobed between the teeth. Fuchsia magellan-
ica lacks the long, drooping branches of some of
the lianoid species from Brazil, and it generally
grows as an upright shrub. In cultivation it can
also reach treelike proportions and is considered
the hardiest (most frost-resistant) of all Fuchsia
species.
A number of different species and varieties have
been recognized by others for what is considered
here to be a monotypic species. Two different color
varieties have been named for plants that lack the
typical red coloration of the floral tube, sepals, leaf
568

Missouri Botanical Garden
veins, and petioles. One, F. magellanica var. mo-
linae, comes from the island of Chiloe; the other,
F. magellanica var. eburnea, is from the southern
Magallanes Region of Chile. Similarly pale-colored
plants are also known from Corral, Prov. Valdivia,
Chile (Gunkel 2133, GH). All of these plants occur
sympatrically with red-flowered populations of F.
magellanica and probably result from minor re-
curring mutations on pigmentation.
Munz (1943: 9) thought that plants from the
southern part of the range, which he called F.
magellanica var. typica, had consistently smaller
leaves and flowers than those from the north, but
this is clearly not the case. Large-leaved plants
occur throughout the range of the species. James
Solomon (pers. comm.) examined many local pop-
ulations in Chile and Argentina and found that
individuals growing in the sun usually have smaller
leaves and flowers than those nearby in shadier
sites. Similarly, clines in leaf size and texture occur
along climatic gradients, such as that along the
shores of Lago Nahuel Haupi in Argentina. The
vegetation in that area becomes increasingly xeric
from west to east, and plants of F. magellanica
respond to this gradient by developing lower, more
compact plants with smaller, thicker leaves.
Populations of plants with small, densely packed
leaves are common on the island of Chiloé, where
high levels of humidity predominate throughout the
year. Larger-leaved individuals also occur together
with these variants. Some of the phenotypic vari-
ants of F. magellanica may also be genetically
determined, as they are known to maintain their
distinctive characteristics under uniform growing
conditions. In horticultural circles, there has been
a strong tendency to assign varietal names to some
of these strains.
In this treatment, I am not recognizing any
varietal or subspecific taxa under F. magellanica,
because it is apparent that a great deal of local
variation exists over the broad geographical range
of the species, without any clear geographical cor-
relations. The species is cytologically uniform, with
over 40 populations counted with 2n — 44. Since
most of the present range of the species, south of
44°S latitude, was completely glaciated during the
major glacial advances of the Pleistocene (Vuilleu-
mier, 1971), there has probably been very little
time for populations to diverge in the southern part
of the range.
In his Flora of Tierra del Fuego, Moore (1983)
cited localities of F. magellanica from as far south
as the Beagle Channel at 55°S, and west to Staten
Island, at 64°W. Collections from these areas were
made in the past century, however, and it is un-
likely that the species occurs there naturally today.
According to D. Moore (pers. comm.), the intro-
duction of goats on Staten Island early in the last
century and the activities of Europeans in the vi-
cinity of the Beagle Channel during the past 100
years have badly deteriorated the woody vegetation
of these areas.
On the drier, Argentinian side of the Andean
Cordillera, F. magellanica occurs natively as far
north as the Lago Quillen, at 39*30'S. Northwards,
the mountains become increasingly arid. On the
Pacific side of the Andes, native populations are
found as far north as Concón (32°50'S), just north
of Valparaiso. These populations grow close to the
coast, along streams in wooded ravines. Looser
(1928) found native populations of F. magellanica
east of Santiago (33?30'S), in the Quebrada de
Penalolén, between 1,450 and 1,750 m, and Navas
(1976) reported the species from the nearby Que-
brada de Macul.
The northernmost extension of Fuchsia magel-
lanica barely overlaps with the southernmost pop-
ulations of the xeromorphic F. lycioides (sect.
Kierschlegeria) in the vicinity of Concón, north
of Valparaiso, Chile. A number of specimens col-
lected in this area during the last century are
morphologically intermediate between the two
species and may represent interspecific hybrids (see
Appendix).

Distribution (Fig. 15). This is the most widely
distributed species of Fuchsia in Brazil, occurring
in the states of Minas Gerais, Espirito Santo, Rio
de Janeiro, Sáo Paulo, Paraná, Santa Catarina,
and Rio Grande do Sul from 18?20'S to 29°30'S
Most common between 700 and 2,000 m, on the
upper, wettest slopes of ranges such as the Serra
do Mar, Serra Geral, Serra da Mantiqueira, and
Serra do Espinhaço. Fuchsia regia subsp. reitzii
is associated with the Araucaria forests of the
southern planalto from Paraná to Rio Grande do
Sul. Plants occasionally occur as high as 2,400 m
on Mt. Itatiaia and at sea level in coastal restingas
of Santa Catarina and Rio Grande do Sul. Flowers
mainly from October to April.
This is the most variable of the Brazilian species
of sect. Quelusia. Three distinct and largely allo-
patric series of populations can be recognized based
on differences in several floral and vegetative char-
acters. They intergrade in areas where their ranges
overlap, and the presence of octoploid populations
in some or all of the populations sampled in each
series is unique in the genus. For these reasons,
the different series are treated here as subspecies
of F. regia.

Fuchsia regia subsp. regia is the most wide-
spread of the Brazilian fuchsias, occurring in four
different states, centered in Rio de Janeiro and
Minas Gerais. As a result of its fragmented distri-
bution, with populations in a number of discrete
mountain ranges, considerable morphological dif-
ferentiation has taken place throughout the range
of this subspecies. It is also cytologically hetero-
geneous, with tetraploid and octoploid populations.
All counts made from Minas Gerais and northern
Rio de Janeiro have been tetraploid, whereas oc-
toploid and tetraploid individuals occur together in
northern Sào Paulo and south-central Rio de Ja-
neiro states, in areas such as Itatiaia, Serra da
Bocaina, and Serra dos Órgáos (see fig. 9 in Ho-
shino & Berry, 1989). The different cytotypes
cannot be distinguished morphologically, however,
and their relationships are not well understood.
Fuchsia regia subsp. regia can be distinguished
from other taxa of sect. Quelusia by having large
flowers with spreading sepals and only slight sepal
connation, large leaves with petioles generally long-
er than 10 mm, and mostly glabrous stems and
foliage.
This subspecies has a particularly broad ecolog-
ical tolerance, extending from tall cloud forest at
1,000 m to open campos as high as 2,400 m.
When it occurs inside the forest, F. regia subsp.
regia grows as a liana, flowering when its branches
reach sufficient light in the tree canopies. As the
vegetation decreases in height with greater ele-
vation, it grows as a scandent shrub, and as a short,
erect shrub when found on the edges of the open
campos. This gradual transition in the habit of
subsp. regia has been observed in several localities,
such as the Serra dos Órgãos and the Morro da
Nova Caledônia in Rio de Janeiro, and the Serra
do Itacolomi and Serra do Itambé in Minas Gerais.
As a result of its broad altitudinal and geograph-
ical distribution, F. regia subsp. regia occurs sym-
patrically with four other species from sect. Que-
lusia. In each case, morphologically intermediate
individuals have been found that indicate the oc-
currence of interspecific hybridization (see Appen-
dix). It also occurs sympatrically with F. regia
subsp. serrae in northern Sào Paulo along the
eastern slopes of the Serra da Bocaina, where it
forms hybrid populations, with further intergra-
dation southwards along the Serra do Mar as far
as Caraguatatuba. These populations are discussed
in the Appendix.
Several collections of F. regia subsp. regia from
widely distant localities are unusually pubescent
yet do not appear to be the result of hybridization
or introgression with pubescent species growing
nearby, such as F. alpestris or F. coccinea. The
specimen Campos Porto 3421 (RB, from Campos
do Jordáo, Sào Paulo, 1,600 m) is similar in all
morphological features to nearby glabrous popu-
lations of F. regia, but the entire plant is covered
by a dense, pilose indumentum. Three collections
from Minas Gerais are similarly pubescent: Gard-
ner 4555 (K), Claussen 88 (G), and Brade 16953
RB, US, from the Serra do Caparaó). Martinelli
et al. 169 (RB, Vale das Videiras, Petrópolis, Rio
de Janeiro) is covered by short, fine pubescence,
which is unusual among the populations of F. regia
from Rio de Janeiro. These pubescent variants
are apparently quite rare, and none were found

during my fieldwork in Brazil.

Fuchsia regia subsp. serrae is the only taxon
in sect. Quelusia besides F. brevilobis with the
sepals connate for over one-third of their length.
It is unique in its persistent, crassate stipules and
lustrous, subcoriaceous leaves with thick petioles.
Unlike the other subspecies of F. regia, the sepals
are usually recurved at anthesis and four-angled
in bud.
This subspecies is most common along the crest
and upper slopes of the ' the steep and
very wet region on the eastern edge of the southern
Brazilian planalto as it drops abruptly to the At-
lantic coastal plains. The rugged terrain, with sheer
“serras,
drops o m or more, such as those found in
the Aparados da Serra in northern Rio Grande do
Sul, creates a broad diversity of microhabitats re-
flected in the large degree of variability in different
populations of this subspecies. For example, low,
densely branched subshrubs characteristically grow
in rock crevices on the steep drop-offs of the Apa-
rados, while tall lianas with long, drooping branches
are found in more protected, forested areas near
the crest of the Serra.
The degree of sepal connation varies consider-
ably in different parts of the range of F. regia
subsp. serrae. In northern Paraná, where it occurs
together with the long-tubed F. brevilobis, the se-
pals are often joined for half or more of their length.
Along the Serra Geral in southern Santa Catarina
and Rio Grande do Sul, however, the sepals are
less joined than populations further north; in ex-
treme cases, individuals like Falkenberg 3744 and
3745 have the sepals joined for only 4-6 mm, but
their thick, shiny leaves and nodose stipules are
characteristic of subsp. serrae.

Fuchsia sect. Quelusia
and southern Santa Catarina, a sharp ecotone oc-
curs between the drier, flatter planalto and the wet,
steep coastal slopes. In this area, Fuchsia regia
subsp. serrae occurs sympatrically with the east-
ernmost populations of Fuchsia regia subsp. re-
itzii, and the two subspecies intergrade extensively
in areas such as Itaimbezinho, Serra da Rocinha,
and the edge of the Serra Geral near Uribici and
Bom Jardim da Serra in Santa Catarina. Further
discussion and a list of intermediate, probable hy-
brid individuals between these two subspecies is
found in the Appendix.
Towards the northern limits of the range of
Fuchsia regia subsp. serrae, this subspecies also
contacts populations of Fuchsia regia subsp. regia,
especially in the Serra da Bocaina in northern Sào
Paulo state. Populations of subsp. serrae predom-
inate there on the lower, coastal slopes below 1,100
m, while subsp. regia occurs at higher elevations
and further inland. Extensive intergradation be-
tween these two subspecies occurs on the upper
coastal slopes of the Serra, where unusually pilose
individuals are also found. Some of these individuals
are octoploid, as in all the southern populations of
subsp. serrae, while others are tetraploid, like some
of the populations of subsp. regia from the Bocaina
range and further north (Hoshino & Berry, 1989).
Although F. regia subsp. regia reaches its southern
limit at the Serra da Bocaina, populations of Fuch-
sia with mixed ploidy levels and dense pubescence
occur south of the Bocaina area as far as Ubatuba
in the Serra do Mar of north-central Sao Paulo
state (Hoshino & Berry, 1989).
Fuchsia regia subsp. serrae also occurs sym-
patrically with F. brevilobis in several localities in
Paraná. Although F. regia is octoploid in this area,
and F. brevilobis is tetraploid, the occurrence of
be d intermediate individuals indicates
at hybridization has taken place between these
taxa (see Appendix). The unusually long sepal tubes
of populations of F. regia subsp. serrae in this area
are characteristic of F. brevilobis and may be the
result of introgression with this species.
Outside of its typical montane habitats, F. regia
subsp. serrae has also been found in coastal res-
tingas at sea level, near the Rio Grande do Sul-
Santa Catarina border. Reitz (1961) first detected
this apparent anomaly in the distribution of typi-
cally montane taxa, and found it to occur in at
least ten other species that normally occur along
the crest of the Serra Geral. The presence of these
species in the restingas must represent recent
chance introductions from the nearby serras, as
the coastal plains of this area are only of Quater-
nary age (Klein, 1984).

Fuchsia regia subsp. reitzii is distinguished by
its whorled, membranous leaves with gland-serrate
margins and a matte surface having more notice-
able tertiary venation than the other subspecies of
F. regia. Compared with F. regia subsp. serrae,
the only other Fuchsia that grows near populations
of subsp. reitzii, the sepals are much less joined
and spreading (instead of recurved), the stipules
are much less prominent, the leaf bases are more
acute, and the berries are rounder. This subspecies
is named in honor of P. Raulino Reitz of the Her-
bário Barbosa Rodrigues, Itajai, Santa Catarina,
who has made great contributions to the knowledge
of the flora of Santa Catarina.
Subspecies reitzii is restricted to the planalto
west of the coastal mountain ranges of southern-
most Brazil. Its overall distribution in this area
parallels that of Araucaria angustifolia, although
it does not tolerate the shade of the dense conifer
forests. Both species extend as far east as the edge
of the coastal escarpments but end abruptly there
580

Missouri Botanical Garden
and do not appear on the seaward slopes or in the
lower, coastal forest (Hueck, 1953
Along the eastern edge of the planalto, where
sharp drop-offs usually occur down to the Atlantic
lowlands, the range of F. regia subsp. reitzii over-
laps with F. regia subsp. serrae, which extends up
from the moist, coastal slopes of the serras. A great
deal of intergradation and variation exists in the
Fuchsia populations of these areas, especially at
the crest itself and just inland of the steep drop-
offs. In some instances, the extreme local variability
is indicative of hybrid swarms, while in other sites,
odd variants are found that can extend beyond the
normal limits of variation of either subspecies (see
Appendix).
A number of unusually pubescent individuals,
usually with conspicuously tan or ferrugineous hairs,
occur in populations near the southern and western
extremes of the range of subsp. reitzii in Rio Grande
do Sul. Collections from the Farroupilha area, such
as Rambo 45781, 45782, and 40172 and Ca-
margo 980, are uniformly pubescent, while others,
such as Rambo 31024 from Vila Oliva near Ca-
xias, and Rambo 51576 from Passo do Socorro
near Vacaria, occur together with more typical
le individuals of the subspecies.

Fuchsia lycioides belongs to a different section,
Kierschlegeria, and differs widely
gellanica in its small, alternate leaves, spinose leaf
bases, smaller flowers with included stamens and
reflexed sepals, and generally occurs in much drier
habitats. Both species are tetraploid (Hoshino &
Berry, 1989) and have been shown to be closely
related by chloroplast DNA restriction site analysis
(Sytsma & Smith, 1988). The ranges of the two
species barely overlap in the hills around Valpa-
raiso, where several natural hybrids were collected
in the early 1800s. These plants are characterized
by small flowers with larger, convolute petals than
those of F. lycioides. The leaves are larger and
more often opposite than in F. lycioides, with the
characteristic dentation of F. magellanica. They
also lack the spinose leaf bases typical of F. ly-
cioides. The natural habitats where the early hy-
brids were collected have probably been totally
eliminated by urban growth.
Hybrids of these two species appear quite often
in cultivation and have sometimes been confused
. ma-
with the true F. lycioides, as in the cytological
study of Chaudhuri (1956).

Fuchsia brevilobis is sympatric with F. regia
subsp. serrae over most of its range but usually
grows at lower elevations. These taxa are unique
in the section in having their sepals connate for
more than one-third of their length, but F. brevi-
lobis has more membranous leaves that are nar-
rower, shorter-petioled, and more pubescent than
F. regia subsp. serrae, while the latter has more
prominent, persistent stipules. The flowers of F.
regia subsp. serrae also differ from F. brevilobis
in their four-ridged buds, glabrous, nitid surface,
and flaring sepal tube. The intermediate individuals
cited above are from three different localities where
the parent species are locally present. In the Ca-
pivari locality, the same hummingbird was observed
visiting flowers of both species in succession.
Further experimental work on artificial hybrids
of these two taxa is desirable, since only tetraploid
counts have been obtained from F. brevilobis, and
all individuals examined of F. regia subsp. serrae
have been octoploid (Hoshino & Berry, 1989). The
count obtained from Cordeiro et al. in 16 Jan
1987 was tetraploid, indicating that it may only
be a variant of F. brevilobis, and that of Berry et
al. 4448 was octoploid, as found in F. regia subsp.
serrae.
4. F. regia subsp. regia X F. campos-portoi
Specimens examined. BRAZIL. RIO DE JANEIRO: Ita-

#61360).
Fuchsia campos-portoi is endemic to the high-
altitude campos of Mount Itatiaia and is very dis-
tinctive in its small, narrow, strongly serrate leaves
and small, short-tubed flowers. Fuchsia regia is
common in forests at lower elevations on the same
mountain range and occurs together with F. cam-
pos-portot in thickets near the treeline above 2,200
m. Both specimens cited above are intermediate in
leaf size, number of secondary veins, and floral
features, such as the ratio of tube to sepal lengths.
Meiosis in buds of Berry et al. 4440 was normal,
with the same chromosome number as recorded in
local parental populations.

Fuchsia coccinea typically grows in thickets
amid the rocky, open campo of the highest peaks
in Minas Gerais. On the Serra do Itacolomi, fire
has destroyed much of the woody vegetation on
the highest slopes; F. coccinea is now very rare
in that area, and intermediate forms with F. regia
are common. In the series of Berry 4545-4550
and Falkenberg 3380-3387, some of the individ-

uals were treated under F. coccinea, but several
of them show signs of introgression with F. regia,
such as leaves that are larger or more coriaceous
and rounder-based than individuals of isolated pop-
ulations of F. coccinea. The collections cited above
are clearly intermediate between the two species
in key characters, such as petiole length, degree
of leaf pubescence, and leaf shape. Both species
are tetraploid in this locality, and the one hybrid
examined cytologically was tetraploid with normal
bivalent formation.
Both species are also known together from the
Pico do Itambe, farther north in the Serra do
Espinhago. Although the collections of Anderson
et al. 35832 and Furlan et al. 3058 were treated
under F. coccinea, they both have unusually thick
leaves for that species, as well as rounded rather
than cordate leaf bases; these traits may be t
result of introgression with sympatric populations
q)
of F. regia.

1,950 m, Berry et a 4427 (MO, RB), 4429
(RB), 4430 (MO, RB; n = 22).
As in the previous two cases, F. glazioviana is
a local, high-elevation endemic that is sympatric
with F. regia near the former's lower altitudinal
limits. Fuchsia glazioviana has small, densely
packed leaves and smaller, narrower flowers than
F. regia. Most of the hybrids were found along
roadsides in cleared areas, and one large patch of
variable individuals was seen in an exposed area
near the upper limit of the cloud forest. Local
populations of both species are tetraploid, as was
the one intermediate individual counted.

Populations of F. regia subsp. serrae and subsp.
regia converge and intergrade extensively on the
upper, seaward slopes of the Serra da Bocaina,
close to the Rio de Janeiro-Sào Paulo border.
Fuchsia regia subsp. regia reaches its southern-
most limits in the Serra da Bocaina, occurring
mostly at altitudes of 1,100-1,550 m on both sides
of the Serra. Fuchsia regia subsp. serrae occurs
exclusively on the lower, seaward slopes of the
same range between 500 and 1,150 m, part of an
almost continuous distribution down the coastal
slopes of the Serra do Mar and Serra Geral as far
as Rio Grande do Sul.
Varied intermediate forms between the two sub-
species occur between 1,150 and 1,350 m on the
upper slopes of the Serra da Bocaina, along the
road from Cunha to Paraty. Most of the fuchsias
in this area, including those cited in the above list,
are unusually pubescent for F. regia. The degree
of sepal connation and the thickness and persis-
tence of the stipules, which generally distinguish
these taxa, vary widely between individuals in this
area, whereas populations higher up on the Serra
and further inland are largely glabrous and fall well
within the normal range of variation of F. regia
subsp. regia. Hoshino = Berry (1989) reported
duals of Fuchsia from
tetraploid and octoploi
this area, further ee the intergradation of
the basically octoploid subsp. serrae and the mostly
tetraploid subsp. regia. Hexaploid hybrids should
be sought in mixed populations.

Tetraploid and octoploid individuals occur side by
side at the Alto da Serra near the crest of the
mountain (Hoshino & Berry, 1989), again with the
unusual pubescence for F. regia and considerable
variability in such traits as the degree of stipule
development. In most other features, however, these
individuals resemble F. regia subsp. serrae more
closely than subsp. regia.

Both of these two subspecies are morphologically
and ecologically distinct over most of their ranges,
with F. regia subsp. reitzii confined to thickets in
the southern planalto and F. regia subsp. serrae
inhabiting the wet, seaward slopes of the coastal
mountain ranges. Fuchsia regia subsp. serrae has
nitid, subcoriaceous leaves with thick stipules and
flowers with strongly connate, recurved sepals, while
subsp. reitzii has thinner, more whorled leaves with
serrate margins, thin stipules, and flowers with
spreading, slightly connate sepals.
À narrow ecotone occurs all along the crest of
the Serra do Mar and the Serra Geral in Santa
Catarina and Rio Grande do Sul as the high rolling
plains end and the steep coastal ranges drop abrupt-
ly to the Atlantic lowlands. Along this belt, which
occurs sometimes just at the crest of the ridges
and other times extends a few hundred meters or
several kilometers inland, the two subspecies of F.
regia converge and intergrade in a bewildering
variety of variants, some of them exceeding the
normal limits of variation of either parental sub-
species.
The narrowest ecotone observed was at the Serra
da Rocinha, on the Santa Catarina- Rio Grande do
Sul border. In this area, the planalto is covered
right to the edge by grassy campos, followed by
steep drop-offs covered by a special “Aparados”
flora adapted to the persistent rains and mists from
the rising coastal air masses (Rambo, 1956). Along
the rim of the serra cliffs, between 1,250 and 1,280
m, hybrid swarms of F. regia subsp. serrae and
reitzii occur together with occasional plants that
can be distinguished as parental, such as those
included in the collection series of Falkenberg et
al. 3756-3766.
Other areas where similar series of intermediates
have been observed and collected include the Apa-
rados da Serra at Itaimbezinho, in Rio Grande do
Sul, and the area around the crest of the Serra
Geral between Bom Jardim da Serra and Lauro
Müller in Santa Catarina. Near the town of Urubici,
Santa Catarina, plants of F. regia subsp. serrae
occur farther inland from the crest of the Serra
Geral, around the base of the Morro da Igreja and
Campo dos Padres, the highest points in Santa
Catarina. Where the two subspecies occurred sym-
patrically, as in the collection series of Falkenberg
et al. 3787-3791 (FLOR, MO; just W of the crest
of the ridge between Urubici and Brago do Norte,
at 1,030 m), some unusual variants of subsp. ser-
rae were found with flowers less than half the
normal size (43790).
oth subspecies are octoploid and are charac-
terized by variable numbers of multivalents during
meiotic metaphase (Hoshino & Berry, 1989); the
one intermediate individual examined had the same
chromosome number and type of meiotic config-
uration.
OBSERVATIONS ON
POLYPLOIDY IN FUCHSIA
Takuji Hoshino? and Paul E. Berry?
(ONAGRACEAE)!
ABSTRACT
Chromosome numbers are reported for all eleven taxa currently recognized in Fuchsia sect. Quelusia and for F.
lycioides, the sole member of sect. AS Results are based on the study of individuals from 103 native
populations and 13 cultivated plants. Most species and sections of Fuchsia are diploid (n = x = 11), but sects.
Quelusia and Kierschlegeria are entirely de ba including the only naturally occurring octoploids in the genus.
Polyploidy in these sections is always associated with 3(4)-aperturate pollen grains, instead of the normal 2-aperturate
condition in the genus. All ona counts obtained from F. lycioides and from seven of the nine species in sect.
Quelusia were tetraploid, but intraspecific variation in ploidy level was found in two Brazilian species of sect. Quelusia.
The only wild individual examined of F. alpestris was tetraploid, whereas a cultivated specimen of this species from
urope was octoploid. In the widespread, polytypic F. regia, all individuals examined of subspecies reitzii and serrae
were octoploid, but both tetraploid and octoploid populations were found in subsp. regia. Both ploidy levels were also
d in the extreme northern range of subsp. serrae, in individuals that were morphologically intermediate with
. This situation suggests that octoploidy has evolved recently and possibly repeatedly in s
sect. Quelusia,
whereas tetraploidy probably originated in a common ancestor to sects. Quelusia and Kierschlegeria.
Fuchsia is one of the largest genera of the
Onagraceae, with over 100 species occurring most-
ly in tropical montane cloud forests. It is placed
in its own tribe, Fuchsieae, on the basis of its fleshy
fruits and mostly 2-aperturate pollen. Chromo-
somes in Fuchsia are large and are heterogeneous
in size for the family, with interphase nuclei having
ycnotic areas that are variable in number, size,
and density (Kurabayashi et al., 1962); these are
unspecialized features shared with Lopezia and
Circaea. All species examined in the genus have
the basic chromosome number of the family, x —
11 (Raven, 1979), and none have the translocation
systems or aneuploidy that are characteristic of
other onagraceous genera such as Oenothera and
Clarkia.
In recent efforts to improve our understanding
of the relationships of the different species and
sections of Fuchsia, the distribution of chromosome
numbers has been determined for as many species
as possible in the genus, together with extensive
surveys of the palynology and foliar flavonoid
chemistry of most taxa (Nowicke et al., 1984;
Averett et al., 1986). To date, diploid chromosome
counts (n — 11) have been obtained for 69 species
and tetraploid counts (n = 22) for 10 species
(Breedlove, 1969; Breedlove et al., 1982; Berry,
1982, 1985; Berry et al., 1988; Hoshino & Berry,
1988). Of the ten sections currently recognized in
the genus (Berry et al., 1988), six are entirely
diploid. The two largest sections, Fuchsia (
species) and Hemsleyella (14 species), are pre-
dominantly diploid, but sect. Fuchsia has six known
tetraploid or partly tetraploid species (Berry, 1982),
and sect. Hemsleyella has two tetraploid species
(Berry, 1985). This paper presents the results of

also presents the first published counts for Fuchsia
lycioides, the sole member of sect. Kierschlegeria.
The only previous reports on chromosomes in
sect. Quelusia were from F. magellanica. The
first report by Warth (1923) was n = 22 for F.
coccinea, but photographs in a subsequent publi-
cation (Warth, 1925) showed that this was a mis-
identification of F. magellanica. Johanssen (19292,
b) reported diploid counts of n = 11 for two hor-
ticultural selections of F. magellanica, but no
vouchers or illustrations were provided to verify
the identity of his plants, which were very likely
misidentified (P. Raven, pers. comm.). A report of
n — 44 in F. magellanica by Haque (1952) also
lacked vouchers. Chaudhuri (1956) made counts
of n — 22 in F. magellanica and noted that it had

distinctly shorter chromosomes than several diploid
species he examined in the genus. Kurabayashi et
al. (1962) examined two different collections of F.
magellanica, which they also found to be tetraploid
with short chromosomes. Although Chaudhuri
(1956) reported a tetraploid count for F. lycioides,
no voucher specimens were provided, and his de-
scription of this entity clearly indicates that it was
a hybrid, probably of F. magellanica x F. ly-
cioides parentage.
MATERIALS AND METHODS
Meiotic chromosomes were examined in pollen
mother cells of young buds fixed in Carnoy's so-
lution (3:1 absolute ethanol to glacial acetic acid)
for 24 hours, then transferred to 70% ethanol for
storage. Anthers were squashed in 1% aceto-or-
cein.
Somatic chromosomes were studied in root tip
apices, which were pretreated in 0.002 M aqueous
8-hydroxyquinoline for 6 hours at 5?C, then fixed

in Carnoy's solution and macerated in 10% HCl
for 6 minutes at 60°C. The root tips were stained
in 1% aceto-orcein for 10 or 20 minutes and then
squashed.
To establish pollen fertility, pollen grains were
stained with Alexander's solution (Alexander, 1969).
RESULTS
Chromosome counts from 40 different popula-
tions of native and cultivated individuals of F. ma-
gellanica were consistently tetraploid (n — 22;
Table 1, Appendix). The populations sampled cov-
ered most of the range of this widespread species
of southern Argentina and Chile, leaving little doubt
that it is cytologically uniform throughout its range.
Counts of all other taxa in sect. Quelusia rep-
resent their first validated chromosome reports (Ta-
ble 1). Seven Brazilian species, including the newly
described F. brevilobis and F. hatschbachii (Ber-
ry, 1989), are all tetraploid, based on at least two
counts for each species. The Chilean F. lycioides

(sect. Kierschlegeria) is also tetraploid. Normal
bivalent formation was found in all tetraploid col-
lections examined (Figs. 1-4). In the Brazilian F.
alpestris, the single naturally occurring individual
counted was tetraploid, but a plant of this species
cultivated in Europe was octoploid.
Fuchsia regia, the most widespread species of
the genus in Brazil, has tetraploid and octoploid
populations (see Appendix). Populations from the
southern half of its range were entirely octoploid,
including all populations counted of subspecies
reitzii and serrae and one naturally occurring hy-
brid between them. In most of the octoploids, nu-
merous quadrivalents and bivalents were formed
(Figs. 5-8).
Populations of F. regia subsp. regia with both
tetraploid and octoploid individuals were found in
northern Sào Paulo and southern Rio de Janeiro
states (Appendix, Figure 9). The southernmost tet-
raploid individuals of F. regia came from north-
central Sào Paulo State. These collections are
morphologically intermediate, probable hybrids be-
tween subspecies regia and serrae. They also
occurred sympatrically with octoploid individuals

and other parts of Rio de Janeiro, all populations
of subsp. regia sampled were tetraploid. The dis-
tribution of the different cytotypes of F. regia is

Although meiosis was not observed in an artificial
hexaploid hybrid between a tetraploid plant of F.
regia subsp. regia and an octoploid one of subsp.
serrae, more than 50% of the pollen grains of the
hybrid were aborted. Both parents, however, showed

DISCUSSION
Sections Kierschlegeria and Quelusia are the
only entirely polyploid sections of Fuchsia. In both
groups, polyploidy is associated with 3-aperturate
pollen, considered to be derived from the more
common 2-aperturate condition in the genus (Now-
icke et al., 1984). Despite differences between the
two sections in viscin thread type (Nowicke et al.,
1984), seed number and anatomy, sexual systems,
and other morphological features (Berry, 1982), a
preliminary chloroplast DNA restriction site anal-
ysis by Sytsma & Smith (1988) has shown the two
sections to be more closely related to one another
than to any other section of the genus. The results
of a separate cladistic analysis of the species of
these two sections by Berry (1989) were consistent
with the hypothesis that tetraploidy evolved in a
common ancestor. Since the other eight sections
of the genus are predominantly diploid, e
the South Pacific sect. Skinnera and al zen-
tral American sections, it is clear that no exiis
member of sect. Quelusia or sect. Kierschlegeria
could have directly given rise to those groups.
Octoploidy in natural populations of Fuchsia is
known only in sect. Quelusia, where it has been
detected primarily in F. regia, a species that also
has tetraploid populations. Quadrivalents are com-
mon in the octoploid individuals examined, indi-
cating a close chromosomal homology between the
genomes that came together. Both the presence of
different ploidy levels and the varying numbers of
multivalents in F. regia indicate a recent origin of
octoploidy in the genus. Whether the octoploidy
detected in F. alpestris originated naturally or
590

under cultivation is not known, but the extent of
the two different chromosome numbers needs to
be examined further in nature. Cases of intraspe-
cific polyploidy are widespread in the Onagraceae
and have been recorded in over 40 species and 11
genera (Lewis, 1979).
The high level of pollen abortion in the artificial
hexaploid between a tetraploid and an octoploid
subspecies of Fuchsia regia is indicative of irreg-
ularities in meiotic pairing and disjunction, which
may explain the absence of naturally occurring
hexaploids among the individuals sampled in areas
where tetraploids and octoploids both were found.
Areas where tetraploid and octoploid populations
of F. regia are known to occur sympatrically, such
as the Serra da Bocaina and Campos do Jordào in
northern Sao Paulo state, and the Itatiaia massif
and the Serra dos Orgaos in Rio de Janeiro, should
be sampled more intensively for naturally occurring
hexaploids.
Within the Onagraceae, the pattern of poly-
ploidy in Fuchsia sect. Quelusia is most similar to
that of Ludwigia, where polyploidy has been a
frequent and important part of the evolutionary
strategy in most of the genus, with numerous cases
of intraspecific polyploidy (Raven & Tai, 1979).
Unlike the situation in tribe Onagreae, where poly-
ploidy is associated with autogamy and aneuploidy
in annual species, aneuploidy is unknown in Fuch-
sia and Ludwigia, and polyploid taxa are perennial
and predominantly outcrossing. This clearly shows
that the effects of polyploidy can vary widely in
related genera, depending on factors such as the
longevity of the species and the habitat in which
they occur.

NOTES ON THE
CORDIA PANAMENSIS
COMPLEX (BORAGINACEAE)
AND A NEW SPECIES
FROM COLOMBIA
Cordia is a large pantropical genus of about
300 species, divided by most recent authors into
six sections (Nowicke & Miller, in press). Section
Myxa, with over 150 species, is the largest in the
Neotropics and includes all but one of the paleo-
tropical species (Miller, 1985). It is difficult tax-
onomically because most of the groups that can be
recognized within the section have obscure bound-
aries.
One such group is the Cordia panamensis Riley
group (Miller, 1985), which is widespread in Cen-
tral America, the West Indies, and northern South
America. This group is particularly problematic in
terms of its definition. within sect. Myxa, as well
as species delimitations within it. It is loosely de-
fined and may very well not be monophyletic, yet
the species all share a similar appearance and are
often confused in herbaria. The C. panamensis
group is characterized by ovate to nhe sca-
brous to scabrid, usually anisophyllous leaves that
generally dry brown. All of the species except C.
anisoph ylla J. S. Miller are dioecious. Perhaps C.
bicolor A. DC. and C. sellowiana Cham. should
be included, but C. bicolor does not dry brown,
and both species differ in being homostylous.

of the C. panamensis group were soaked in 5%
NaOH for two days to soften the exocarp and
mesocarp, then washed in running water to remove
yxa (Miller, in prep.) but has not
outer tissues and expose the cleaned, outer surface
of the endocarp. Cordia gentryi has an endocarp
with raised, quadrangular areas (Fig. 1C); in C.
anisophylla the raised areas are much longer (Fig.
1 D). Other members of the group have rugulose
(C. panamensis, Fig. 1E) to spinulose (C. Aebe-
clada I. M. Johnston, Fig. 1F) endocarps.
Recent studies of members of the C. panamensis
group have helped clarify the relationships of species
in Central America (Miller, 1985, 1988) and Ven-
ezuela (Gaviria, 1987). The group is defined here
as consisting of ten species, but problems still exist

phylla. | have seen little material of C. macro-
phylla and have maintained it as separate following

Cordia gentryi is most easily distinguished by
its caudate leaf apex and large, orange-yellow fruits.
It most resembles C. panamensis and C. aniso-
phylla J. S. Miller. Cordia panamensis differs in
having hirsute twigs and white fruits shorter than
7.5 mm. Cordia anisophylla differs in having thin-
ner ellipsoid fruits 6-7.5 mm broad and less-pro-
longed leaf apices.

NOTES
A NEW ASPIDOGYNE
(ORCHIDACEAE) FROM
VENEZUELAN GUAYANA
The genus Aspidogyne Garay is one of the
recent segregates from Erythrodes Bl. (Garay,
1977) and comprises 27 species, widely distributed
in the American tropics, primarily Brazil. They are
small to medium-sized terrestrial, humicolous, to
(rarely) subepiphytic herbs growing in mostly shady
places of rain or cloud forests.
Aspidogyne belongs to the pantropical subtribe
Physurinae, of seven genera. Among them, As-
pidog yne can be recognized by the following com-
bination of features: horizontal stigmata; elongate,
erect column; and entire emarginate rostellum.
A revision of the Aspidogyne species of the
Venezuelan Guayana for the orchid treatment in
Steyermark's Flora of the Venezuelan Guayana
has revealed a different identity for the species that
appeared in Foldats 70) as Erythrodes picta
(Lyndley) Ames, a synonym of 4spidogyne ar-
gentea (Vell.) Garay. Foldats had already noted
that the Venezuelan material cited under £. picta
differed from the type, and suggested that it might
represent a new variety. New evidence shows that
the differences are sufficient for recognition of a
new species, described below.

subacute. Spur cylindric, acute, slightly arched,
.2 mm long, 0.7 mm thick. Column clavate,
mm long; rostellum aristate, acute.
This new species belongs in sect. Argenteae
Garay. It is similar to Aspidogyne argentea (V ell.)
Garay but differs by having acute (vs. rounded or
obtuse) dorsal sepals, cylindric (vs. fusiform) spur,
petals apically not lobulate, and the labellum with
a transversely rhombic, subacute (vs. transversely
obreniform, truncate, apiculate) apical lobe.

Bomarea bracteolata is probably most closely
related to B. allenii Killip, the only other large-
flowered Mesoamerican Bomarea with branched
umbel rays. These species differ in sepal length
(4.1—4.8 cm in B. bracteolata, 5.3-6.5 cm in B.
allenii), lower leaf surface (pubescent in B. brac-
teolata, glabrous in B. allenii), and length/ width
ratio of leaf blades (2.5-2.7 in B. bracteolata,
4.0-5.4 in B. allenii). The inflorescence and flow-
ers of B. bracteolata are very similar to those of
B. kranzlinii Baker of Colombia (cf. Stein &
McDade 3205, MO), but the latter species has
smaller bracts and bracteoles and narrower leaves
that are glabrous beneat

HOSTA YINGERI
(LILIACEAE/FUNKIACEAE):
A NEW SPECIES
FROM KOREA
The genus Hosta Tratt. includes ca. 22-25
species of rhizomatous herbaceous perennials from
Japan, China, and Korea. The genus is well known
to gardeners in the United States, Europe, and
New Zealand, since the species and cultivars are
widely grown in shady gardens for their attractive
foliage and flowers (Aden, 1988). They are also
grown as ornamentals and eaten cooked in China,
Japan, and Korea. Traditionally Hosta has been
placed in the Liliaceae (e.g., Cronquist, 1981) or
in the Funkiaceae (Dahlgren et al., 1985) along
with Hesperocallis A. Gray and Leucocrinum Nutt.
ex A. Gray, both from western North America.
Bailey (1930) and Stearn (1931) noted that
Hosta is a taxonomically difficult genus with con-
fused nomenclature. Although a number of papers
have been published on Hosta during the past 50
years, there has been little improvement in our
understanding of the genus. The matter has been
largely complicated by broad (Fujita, 1976) or
narrow (Maekawa, 1940) species concepts and
confusion caused by cultivars. The plants have
relatively few good diagnostic features that can be
observed in pressed and dried herbarium specimens
(Hylander, 1954). In an attempt to improve our
knowledge of Hosta, my associates Carleen Jones,
Myong Chung, and Haynes Currie and I have been
attempting to assemble a collection of living hostas.
Several years ago Barry R. Yinger, then of the
U.S. National Arboretum, supplied seeds of several
accessions of Hosta collected from Taehuksan Is-
land, a remote island off the southwestern coast of
orea. Examination of my cultivated plants and
field-collected vouchers at NA reveals a new species,
named in honor of the collector, Barry Yinger.

Hosta yingeri is distinct from other species of
Hosta in its relatively thick, adaxially dark green
leaves. This feature may be an adaptation to its
coastal habitat, growing at 2-60 m above sea level.
It is also distinguished by its delicate raceme of
flowers spread evenly around the central axis of
the inflorescence; typically, Hosta has subsecund
racemes. An additional diagnostic feature of H.
yingeri is the exceptional length of the second set
of stamens, with both sets exserted well beyond the
perianth. Our living material has been compared
with representative accessions of all species of Hos-
ta in our garden and with loans of herbarium ma-
terial. Hosta yingeri is an attractive and interest-
ing new species with horticultural potential. It
appears to be associated with Maekawa's (1940)
subgenus Bryocles, section Tardanthae. Hosta
yingeri does not resemble our garden-grown ma-
terial of H. tsushimensis obtained from the Na-
tional Arboretum.

LINDSAEA MESARUM, A
NEW FERN SPECIES FROM
THE RORAIMA SANDSTONE
When the present author published his revision
of the New World species of Lindsaea (Kramer,
1957), the collection Tate 430 (NY) was cited as
a probably distinct but as yet insufficiently known,
undescribed taxon. This taxon is now known by
over 20 collections and is therefore described as
new.

ezuela.
Rhizoma breviter repens, squamis parvis, fuscis vesti-
ginis, vel continui ad pinnulas minores; indusium firmum,
marginem subaequans. Sporae triletae.
Rhizome rather short-creeping, 1.5-2.5 mm
diam.; scales fuscous, small, narrowly triangular
with broad base, acuminate, ca. 1 x 0.2 mm, ca.
8-seriate at base. Leaves a few-several mm apart;
petiole usually lustrous, atropurpureous to black,
smooth but the basal part bearing some small wart-
like bases of shed scales: adaxial (sometimes also
abaxial) side flattened (near the apex) to faintly
sulcate, abaxial side otherwise rounded; length ca.
12-22 cm, equaling the lamina to much exceeding
it. Lamina narrowly oblong, ca. 10-20 cm long,
paucijugate-bipinnate, or a few once-pinnate or
subbipinnate sterile leaves present beside the bipin-
nate fertile ones; primary rachis dark reddish to
blackish brown, abaxially faintly biangular to dis-
tinctly sulcate. Pinnae from 1 odd one to more
often 1—3 pairs and a conform terminal one, mod-
erately to very strongly ascending, hence the width
of the lamina quite variable; lateral pinnae with a
petiolule of ca. 8 mm, 7-10(-16) cm long, up to
15 mm wide, somewhat narrowed near the base,
gradually and strongly tapering to the apex. Sec-
ondary rachises medium to dark brown, dull, adax-
ially sulcate, the groove bordered by rounded ridges,
abaxially subacutely biangular. Pinnules close to
contiguous or even overlapping, coriaceous, often
blackish when dry, dull or adaxially sublustrous,
dimidiate, spreading or somewhat ascending, up to
ca. 25 well-developed ones to a side, above these
some much-reduced pinnules, a few finally con-
fluent into a short, pinnatifid pinna-apex. Larger
pinnules ca. 6-9 mm long, 3.5-5 mm wide, about
1.5 times as long as wide, semiovate to subtrian-
gular, base cuneate, posterior margin straight or
convex, anterior margin approximately straight,
entire or more often distantly and shallowly incised
to ca. 0.5 mm, the lobes flanking the incisions
mostly touching to overlapping, thus the incisions
inconspicuous. Inner margin of pinnules straight,
diverging from the rachidule, an outer margin not
developed; all margins, especially the posterior,
sclerotic, apex subacute to obtuse but not rounded.
Sterile pinnules very shallowly and rather irregu-
larly crenate. Veins immersed but somewhat evi-
dent, adaxially often slightly impressed in dry spec-
imens, free, simple or the inner forked above the
base, ca. 5-8 vein-ends per pinnule present. Sori
occupying the anterior margin, interrupted, or in
small pinnules continuous, (1-)2-5 per pinnule,
each on 1-4(-6) vein-ends, ca. 1.5-4 mm long;
indusium firm, entire, often somewhat undulate (not
sinuate!), about equaling the margin, ca. mm
wide. Spores trilete, subtetrahedral, tawny, smooth,
with prominent laesura, ca. 35 um (proximal) x
26 um (lateral view).

1,800 and 2,800 m. The species is often described
as being locally common.
The interrupted sori were at first taken for an
abnormality due to incomplete fertility of the leaves,
as is often seen in the genus. The constancy of the
character, however, leaves no doubt about its being
a distinctive feature of the species.
Lindsaea mesarum resembles L. stricta (Sw.)
Dryander var. jamesoniiformis Kramer in habit,
but this is certainly due to convergence. The two
taxa occur in the same habitat and are sometimes
collected next to each other. The closest relative
of L. mesarum is L. klotzschiana Moritz ex Et-
tingsh., which has thinner, much more pronounced-
ly incised pinnules and larger rhizome scales.
Another probable relative is L. parkeri (Hooker)
Kuhn subsp. steyermarkiana Kramer, a little-
known taxon of somewhat uncertain status; it has
thinner pinnules that are much less narrowed to-
wards the apex. If the inconspicuous incisions of
the anterior margin of the pinnules of L. mesarum
are overlooked, it will key out to £. stricta (Sw.)
Dryander in the present author's key (Kramer,
1957); from this it can be distinguished by its
smaller rhizome scales, and the forms of L. stricta
with dark leaf axes have strongly rounded pinnules.
The author is indebted to the Curators of the
Herbaria MO, NY, and UC for lending and/or
donating material, and to Mr. A. Zuppiger, Zürich,
for preparing the illustration.

This small and inconspicuous passionflower is
known from four areas of lower montane rainforest
in Costa Rica. Passiflora nubicola grows at edges
of primary forest, in treefalls, or along trails, where
its thin wiry dark green stems trail over fallen logs
and among grasses, bushes, and small trees. The
leaves are similar in shape to those of a juvenile
P. biflora Lam., and their flecks of white varie-
gation are similarly distributed. The flower also
resembles that of a miniature P. biflora, but in the
Orosi valley possesses only one row of coronal
filaments. The species is closely related to P. bi-
ora.
At the Monteverde Reserve, the main herbivore
of this species is Heliconius clysonimus (J. Mallet,
pers. comm
The clone on the same plant as the holotype
of this species was grown at Duke University 1977-
1983, and the chromosome count was determined
from the clones of this plant. Floral anthesis was
around 0830 hrs. in the greenhouse, with the flow-
ers closing in the early afternoon. No fruits were
set by autogamy during cultivation, and more than
40 attempts at self -pollination also failed to produce
fruit. Passiflora nubicola was very fertile in both
directions with P. biflora (MacDougal 260GR &
275GR), yielding well-seeded fruit and vigorous F,
progeny. Those progeny, generally morphologi-
cally intermediate in vegetative and reproductive
character states, had variously malformed flowers
and were sterile, producing no viable pollen. Fruits
(with hybrid embryos) produced on P. nubicola
matured in 45-48 days and contained 35-64 seeds
per fruit (N — 13 fruits).
The epithet means *'cloud-dweller,"
to its habitat of misty forest.

Passiflora gilbertiana is remarkable for its var-
iegated reddish purple leaves and stinking golden
flowers. It is a member of a species group of Central
American passionflowers in section Decaloba char-
acterized by bilobed variegated leaves, greenish to
yellow perianth, filiform unbanded outer coronal
filaments, and notable reduction in the size of the
petals relative to the sepals. This group is part of
section Decaloba but was not recognized by Killip
(1938), who scattered its component species among
of section Decaloba.
several of his invalid *'series"
Within the group, the new species is most closely
related to P. jorullensis H.B.K. of Mexico, P.
apetala Killip of Costa Rica and Panama (Fig. 3),
and an undescribed relative of P. apetala from
the mountainous border of Mexico and Guatemala.
Its distinctive characteristics include its long nar-
row leaf with a relatively small interlobe angle and
more strongly expressed red to purple coloration,
retention of conspicuous laminar variegation at ma-
turity, and yellow flower with small petals and
second (inner) series of coronal filaments. The inner
series of coronal filaments varies as to presence or
absence within the species. In Taylor & Skotak
4771 the series is well developed, numbering ca.
40; in the type it is absent. However, the cultivation
of somatic clones (MacDougal 655) from the type
plant revealed that the expression of the second

filamentous series was variable within this individ-
ual, with (0-)5-12(-20) filaments per flower. The
expression changed gradually along the stem, at
times stronger, at times weaker, perhaps dependent
on environmental conditions. In certain cases the
expression seemed to be related to the position of
the flower on the vine, with smaller flowers near
the end of flowering axillary branches completely
lacking the second series.
On the label of the type is the collector's note
"odor of pigpen." The flowers of this new species
share this strong odor (described as between “ster-
coraire et putride" by Planchon, 1849) with P.
jorullensis (pers. obs.). Gilbert also noted on the
type label **visited by hummingbirds,” but the same
day he also observed a single wasp flower
(pers. comm.). It is thus probably significant that
P. jorullensis, with a nearly identical odor, is pri-
at a
marily wasp-pollinated at least in some part of
Mexico (MacDougal, unpubl.).
The habitat at the type locality is treefalls and
partially shaded thickets along a dirt road on steep
slopes in the lower reaches of Alnus forest. Plants
there climbed over bushes and trailed into small
Alnus and Piper trees. An important herbivore at
the type locality is a yellow flea beetle that is an

undescribed species of Monomacra (from Mac-
Dougal 1431, voucher identified by C. Duckett,
deposited in the Cornell University Insect Collec-
tion). Several of the cited specimens show char-
acteristic damage by flea beetles.
A clone from the type collection was cultivated
at Duke University and from there was distributed
to several commercial greenhouses in California
and made available for sale to the public by 1980
In cultivation the plant bloomed from the morning
to afternoon, with anthesis around 0930 hrs. and
flower closing in mid to late afternoon. The stigmas,
although lowered to anther level into the afternoon,
were not receptive after ca. 1230 hrs. No fruits
were set by autogamy during cultivation, but during
limited hand-pollinations, 6 of 11 self-pollinations
before 1230 hrs. produced mature fruit containing
19-31 seeds per fruit.
Mr. Patrick Worley, a commercial plant hy-
bridizer, crossed a clone of the type with P. biflora,
P. ornithoura Masters (MacDougal 623), and P.
jorullensis (MacDougal 368); many F, progeny
were grown to maturity and all flowered. Pollen
viability was not examined. In each case the un-
pleasant odor was conserved. One especially or-
namental individual of the cross with P. jorullensis

was named *'Sunburst" and has been available to
the public from several nurseries since 1983.
I take great pleasure in naming this species for
its discoverer, Lawrence E. Gilbert of The Uni-
versity of Texas at Austin, whose seminal contri-
butions to the understanding of the ecology of the
Passifloraceae and their herbivores are well known.
Dr. Gilbert first suggested the study of passion-
flowers to me and has aroused and guided an in-
terest in these plants in many other students. It is
particularly gratifying to name this plant because
had the privilege of being with Dr. Gilbert the
day he discovered it and gathered the type collec-
tion. He immediately suspected it to be undescribed
and his exuberance kindled in me what has become
a career.
Many of the observations given here were made
at Duke University, and I gratefully acknowledge
Donald E. Stone for his inspiration and guidance
during my graduate studies. Thanks are due the
Organization for Tropical Studies for their summer
field course that introduced me to Lawrence Gilbert
and to these Costa Rican passionflowers. The staff
of the Duke University greenhouses provided many
years of favorable conditions for passionflower vines,
and the Jessie Smith Noyes Foundation generously
provided postdoctoral support for research on this
family at the Missouri Botanical Garden. The draw-
ings were prepared by John Myers.

PASSIFLORA MAYARUM,
A NEW SPECIES RELATED
TO P. PROLATA IN
SUBGENUS PASSIFLORA
(PASSIFLORACEAE)
Collections from Central America made since
the time of Killip's (1938) monumental monograph
of the American Passifloraceae have allowed a
clearer delineation of a number of taxa, and in
some cases have confirmed his suspicions that cer-
tain specimens might represent undescribed species.
Such is the case with Passiflora prolata Masters
and its apparent sister species newly described here.

western Belize, and the southern part of the Yu-
catán Peninsula (Fig. 2). The collections come from
elevations of 20-250 m, except for two collections
from one station at 550 m in Belize. The habitat
is usually open or partially open vegetation. Al-
though the information is not present on the spec-
imen's label, Bartlett (1935: 20) stated that his
collection 12840 was collected in the wooded swamp
vegetation called escobal, which is a vegetation
type dominated by the escoba palm, Cryosophila.
This edaphic climax occurs in the Petén and Yu-
catán on wet soil surrounding water holes (““agua-
das") and as the transitional zone between the
inundated areas of the w
and the well-drained **high bush” uplands (Bartlett,
1935; Lundell, 1937). However, most of the col-
lections are from disturbed and more well-drained
habitats, namely, roadsides and secondary areas in
low forest, selva mediana subperennifolia, or sel-
va alta subperennifolia (Rzedowski, 1978).
Phenology.
The few collections known sug-
gest that reproduction occurs primarily during the

Passiflora mayarum is most similar to and is
undoubtedly very closely related to P. prolata from
the premontane to montane broad-leaved forests
of the Pacific watershed of Guatemala and Chiapas,
Mexico. Except for the vestiture, the two have
similar leaves and nearly identical glandular bracts.
At the time of his 1938 monograph, Killip knew
Passiflora prolata only from the type. He knew
the related species newly described here from a
single collection by Bartlett (12840). He had iden-
tified that sheet as P. prolata (Killip, 1936), but
later expressed some misgivings. In his monograph
(1938: 389) he stated, “I am referring the Bartlett
collection to P. prolata with some hesitation, as
the stem and under surface of the leaves are pu-
berulent and the petiolar glands are not quite as
in the type. It comes, moreover, from the low-
lands." The more recent collections of both species
confirm that the two are separate morphologically
and ecologically. Neither fruit nor seeds are known
from P. prolata, so it is impossible to compare the
two species on these points. They may be distin-
guished by the following key.

not nectariferous at the junction of the petiole.
Bracts puberulent abaxially. Hypanthium pu-
berulent, sepals puberulent or only sparsely so.
Habitat elevation 20-550 m „u P. mayarum
Not having seen the type of P. prolata (Leh-
mann 1630—G-BOIS), I have relied on the pro-
tologue and five more recent collections, including
one of my own, that match the protologue. Three
of these collections were identified as P. prolata
by Killip (who saw the type), and one was collected
within 30 km of the type locality at a similar
elevation. The flowers of P. prolata and P. may-
arum appear to be rather similar, apparently borne
above the horizontal plane, with two prominent
series of purplish outer coronal filaments, several
reduced intermediate series, and a well-developed
inclined inner series. The operculum in both is
similar, although that of P. mayarum has shorter
subapical filaments. I have seen the flower of P.
prolata only from Matuda 16479 (F), in which
the intermediate coronal series are reduced to var-
iably expressed series of tubercles. It is not possible
to determine clearly the relative length of the two
outer series except to say that they are roughly
similar in this poorly pressed specimen. Given the
lack of comparative reproductive material and the
coronal variation that occurs within related species,
I have for now distinguished the two species mainly
by vegetative characteristics.
he leaves of P. mayarum tend to be less deeply
lobed, but there is considerable overlap with P
prolata. The quality and quantity of the indument
differ: the few trichomes that occur on the leaves
and nodes of P. prolata are ca. 0.2-0.4 mm in-
stead of 0.05-0.25 mm long. Despite the variation
in their vestiture, the bracts of both species always
have a narrow band of dense tomentum along the
margin adaxially. The trichomes are crispate, and
those of adjacent bracts are interlocked during the
development of the bud, keeping the bracts valvate.
This marginal band of crispate tomentum occurs
in number of species of Passiflora and is correlated
with foliaceous valvate bracts. The ovary of
mayarum is glabrous in all collections exiled
except Tün O. 1374, in which it is sparsely pu-
berulent.
Some of the Mexican collections of the new
species were distributed as P. platyloba Killip and
are cited as such in Sousa & Cabrera (1983).
Passiflora mayarum and P. prolata belong to
subgenus Passiflora, where they share character-
istics with species that Killip (1938) included in
his informal *'series" Serratifoliae and Incarnatae.
618
Annals of the
Missouri Botanical Garden
Killip placed P. prolata next to P. incarnata L.
as one of six species in /ncarnatae, which was
MSE n = Passiflora (as sub-
nus “Granadilla”) as having unwinged stems,
free te narrow stipules, lobed leaves, eglan-
dular sepals, filamentous corona in more than two
series, petiolar glands present, and denticulate or
fimbriate operculum. That delineation is fraught
with difficulties since most of those character states
are undoubtedly plesiomorphic for the subgenus.
Except for the lobed leaves, it also fits the species
put in the Serratifoliae group. An understanding
of the relationships among these species and the
granadillas as a whole awaits a revision of subgenus
Passiflora. Passiflora mayarum is probably ge-
netically close enough to the commercially impor-
tant P. edulis Sims to warrant investigation into
using it as a rootstock or as a source of genetic
rovement for the commercial passionfruit. It is
especially notable that P. mayarum has been col-
lected growing in warm wet soil, the kind of con-
ditions that induce fungus-related failure of the
commercial crop
The epithet mayarum refers to the native dis-
tribution of this species, centered in the heart of
the Mayan Old Empire
I am grateful to the Jessie Smith Noyes Foun-
dation for postdoctoral support for research on
passionflowers, to the curators of the herbaria listed
above, and to John Myers for the drawing.

TWO NEW SPECIES OF
TOURNEFOR TIA
(BORAGINACEAE)
FROM COLOMBIA
Recent collecting efforts in western Colombia
have yielded two very distinct and undescribed
species of Tournefortia L. Both are members of
sect. Tournefortia, a pantropical group with its
center of diversity in Andean South America.
Species of Tournefortia from this area remain con-
fused, since the most recent taxonomic treatment
available is de Candolle's (1845). Macbride (1960)
covered the species from Peru, but his treatment
is regional and incomplete. Killip prepared an un-
published treatment of the Andean species. The
following two species are new.

Fruits unknown.
Tournefortia brantii is a member of sect. Tour-
nefortia and belongs to a group of about 10 poorly
defined species that have opposite leaves. These
species occur from Costa Rica through Colombia,
Ecuador, Peru, and into Bolivia and are centered
in the northern Andes. While problems exist with
species delimitation among the opposite-leaved
species of Tournefortia, T. brantii is distinct among
the South American species by having dark brown
indument and sepals to 5 mm long. It is most similar
to T. johnstonii Standley, a species of Panama
(Miller, 1988), which differs in having sepals longer
than 6 mm and a corolla tube 8-10 mm long. The
other species of Tournefortia with opposite leaves
in Colombia, 7T. pauciflora Nowicke and T. sca-
brida Kunth, differ in having shorter calyces and
less prominant indument on the twigs (Nowicke,

A NEW SPECIES OF
URGINEA (LILIACEAE)
IN NIGERIA
The genus Urginea Stein. is represented i in | West
Kunth, U. ensifolia (Thonn.) Hepper, U.
pauciflora Bak., and the variable U. altissima (L.)
Bak., which was recently discovered to resolve into
a complex of three species: U. altissima (L.) Bak.,
sensu stricto, U. gigantea (Jacq.) Oyewole, and U.
viridula Bak. (Oyewole, 1975). Samples of wild
populations continue to reveal the inadequacy of
the existing taxonomy of the genus. For instance,
complexes such as in U. indica (Oyewole, 1987)
or entirely new variants are being discovered.
Hence, a revision of the genus is due.
The present report describes a recently discov-
ered wild population of a new species within the
main campus site of the University of Ilorin, Kwara
State, in west central Nigeria.
EcoLoGY
The flora of a rock outcrop located about 1.5
km to the east of the academic area of the main
campus site of the University of Ilorin, about 20
km outside the city of Ilorin, was first sampled in
May 1982. The site of the rock was to be part of
a proposed botanical garden.
About 100 tiny bulbs of an evidently new rep-
resentative of Urginea were collected between May
1982 and February 1983, from the shallow soils
of the outcrop. The soil is brown and lateritic, with
occasional dark humus in depressions. The vege-
tation is low grassland, with few small trees of
Entada africana, Erythrina pulcherrima, and
other legumes interspersed with stands of Butyro-
spermum paradoxum and Lophira lanceolata,
and low stands of Cochlospermum sp. Herbaceous
species of Commelinaceae and Asteraceae are com-
mon among low grasses. Seasonal marshes and
ponds support the growth of various Cyperaceae,
Anthericum nigericum, and many low, herbaceous
Acanthaceae and Scrophulariaceae.
ulbs of U. nana occur in an unshaded area
with low grass and forb cover. Other bulbous geo-
phytes occurring in the same habitat and inter-
spersed with U. nana are Dipcadi tacazzeanum
(Hochst. ex A. Chev.) Bak. (D. filamentosa Mor-
ton) and Pancratium hirtum A. Chev

long as well as in circum.; seeds dark brown to

sity of Ilorin, 00/2121, 500/2229, 500/2230,

These bulbs resemble U. pauciflora in being
few-flowered, and the depauperate morphs of U.
indica in having linear-lanceolate, stiffly erect leaves
and few-flowered inflorescences. They differ, how-
ever, in the form and width of the vegetative leaf,
and in the size of the scape and the positioning of
the flowers on the inflorescence. Examination of
the herbarium specimens at the Herbarium of the
Forest Research Institute of Nigeria (FHI), Ibadan,
and at the University of Ibadan Herbarium (UIH)
revealed that such specimens have not been col-
lected previously in West Tropical Africa. Earlier
examination of materials at Kew also showed that
specimens of this taxon have not been recorded.
Certain variations were observed in the floral
and vegetative morphology, on the basis of which
the population was segregated into three morphs
designated A, B, and C. This informal categori-
zation was necessary for the purposes of karyotypic
examination and eventual cytogenetic studies.

bulb neck. Leaves thin, narrow, coiled (filiform),
10-15 cm long, 1-2 mm broad, dark green, cres-
cent-shaped in transection. Peduncle up to 2.5 cm
high outside of the bulb neck, thick and stiffly erect,
green, bearing 2-3 flowers terminally. Tepals 8-
10 mm long, 2-3 mm broad, yellowish green with
hyaline margin.
rph B. Bulbs ovoid-spherical, 2-3 cm high
and diam., with a conspicuous bulb neck as high
as 4.5 cm. Leaves thin, narrow, coiled, light green,
crescent-shaped in transection, 8-12 cm long, about
l mm broad. Peduncle stiffly erect, 3-4 cm high
outside of the bulb neck, pinkish to purple, usually
bearing 3-6 flowers terminally. Tepals pinkish tint-
ed green on the margin, 7-8 mm long and ca. 2
mm broad.
Morph C. Bulbs small, oval-globose, 0.75-
1.5 cm diam., 1.5-2.5 cm high, with relatively
short bulb neck. Leaves light green, acutely erect,
linear-lanceolate with open transcection and shortly
apiculate apex, 15-20 cm long, 2-3 mm broad.
Peduncle thin, erect but not firm, up to 2.5 cm
high outside of the bulb neck, bearing one terminal
flower usually. Tepal greenish with hyaline margin,
6-7 mm long, about 1 mm broa
The floral dimensions of the three morphs over-
lap so that they are not easily distinguished, but
morph C differs distinctly in vegetative morphol-
ogy. Plants of U. nana must have escaped rec-
ognition for so long because of their habit of growth:
the fruiting shoot is hardly seen above the heap of
burnt litter; the inflorescence begins to emerge
from the soil less than 36 hours after the first
burning. The flower and fruit colors merge with
that of the dark brown soil surface once the charred

vegetative leaves pass easily for the leaves of Bul-
bostylis fimbristyloides and related sedges. The
leaves are not evident when the plant flowers but
rather are produced when the surrounding vege-
tation is luxuriant.
Following is a taxonomic key for separating the
three morphs and their close relatives within the
genus:

DISCUSSION
rginea is probably of recent origin in West
Tropical Africa (Oyewole, 1975), arising probably
like its very close relative Albuca L. from southern-
southeastern Africa and migrating across central
Africa into the west (Oyewole, 1971). It is therefore

conceivable that, faced with myriads of ecological
niches in this region, the number of representative
species and infraspecific taxa is likely to be much
higher than Hepper (1968) recognized. The distinct
morphology of U. nana, with its peculiar habitat,
sets it apart from previously known species of the
genus. However, the existence of different morphs
within a seemingly uniform ecological niche sug-
gests that the population of U. nana may not
entirely represent one genetic system. It is hoped
that investigations now in progress on aspects of
the biosystematics of this species will resolve this
problem before long.
The discovery of U. nana in Nigeria underscores
the fact that the latest treatment of Liliaceae in
West Tropical Africa (Hepper, 1968) is due for
revision. It also indicates that Urginea may be
represented in this subregion by many more taxa
than are now known (Oyewole, 1975).

People were Julian Steyermark's first love, but
flowers were his second. He was a passionate man,
and some of his passions were shaped by early trips
out of a St. Louis that was crowded and smoky
into the gentle Missouri countryside, where he and
his friends first sought unusual birds. Later he
reveled in the autumnal drifts of asters, in enjoying
the purple-brown trilliums and delicate orchids of
early spring, and in collecting samples from the
legions of sedges that he could see only dimly
through the torrential cascades of sweat that poured
from his brows as he crouched over gravelly riv-
erbars during the torrid Missouri summers. Even
the long-exserted anthers of the ribworts that ap-
peared in early summer must have fascinated this
unusual young man, who grew in knowledge about
the diversity of plants that nurtures all who take
the time to stop and appreciate it.
Everywhere he went Julian was recognized for
his achievements: the governments of Guatemala,
Ecuador, and Venezuela; his alma maters at Wash-
ington University and here at the Garden; the
Missouri Department of Conservation; and the Sier-
ra Club all soon came to know him as an inspiring
and unique individual, and gave him abundantly
of their prizes and awards. Everyone knows that
Julian collected more plant specimens than anyone
else has ever done, an incredible 132,000 speci-
mens, and that he was a prolific writer and her-
barium worker. In fact, if we hadn't known him
personally, we might think —reading about his ac-
complishments—that he was some sort of drudge,
dreadful, demanding, and uninteresting. Nothing
could have been farther from the truth, however;
those of us who had the privilege of enjoying his
company, whether in the field, listening to his fa-
vorite music, or simply exchanging views on some
current topic, know far better.
Julian certainly did enjoy hard work, and ap-
preciated all of those wonderful manifestations of
recognition that were accorded him for his accom-
plishments—to be included in the Guinness Book
of World Records as the world's champion plant
collector was for him an absolute delight. In his
life, however, he was sustained to a far greater
degree by the love of his many friends. Boyhood
friends who ranged through the Missouri woods
together searching for rare warblers retained the
joys of their mutual admiration into the years of
maturity. Those who had the privilege of climbing
the steep, rocky slopes and breaking through the
interlocking branches of the forests of Venezuela
with him never forgot the experience, and ex-
pressed their deep concern during his final illness.
Once you knew Julian, you simply did not forget
im.
Returning here to his boyhood home at an age
when most have slipped into the relaxation and
hazy days of retirement and gentle decline, Julian
undertook the preparation of an account of the
plants of what is perhaps the least-known part of
the world botanically, the interior of Venezuela,
where the tepuis and gorges that he loved so deeply
make up the spectacular fabric of the fabled Lost
World. As he did everywhere he lived and worked,
Julian renewed sturdy old friendships, and forged
new ones, a process that continued all his life. Bruce
and Luther, Gerrit and Jeany, Tamra and Bruno,
and so many others—you each gave him much,
especially during his final days of great physical
discomfort, but you got far more than you gave.
Julian's open, happy smile; his sweet, joyous, and
dedicated personality; his attentiveness to the task
at hand; and his unremitting, dignified friendship
will form memories that will be with each of us
until our own final days.

diums, gumweeds might have seemed a strange
choice as the subject of a doctoral dissertation.
These sunflower relatives exude a white, sticky sap
that fills their unopened flower heads before they
expand to reveal the golden-yellow inflorescence
hidden within each. Gumweeds are relatively un-
common in Missouri, but range widely over the
American West and Mexico. Julian's graduate ad-
visor, Jesse Moore Greenman, who trained an en-
tire generation of American taxonomists here in
St. Louis, was determined to complete the great
task of John Torrey, George Engelmann, and Asa
Gray —to make known the variety and complexity
of the plants of our continent, and he assigned
doctoral problems accordingly. For this purpose,
)r. Greenman enlisted Julian, who was afire with
his love of plants, into his army; and the young
man set out along the dirt tracks and across the
fields of the West, publishing his work ultimately
in the Garden’s Annals.
the 28-year-old Julian Steyermark, just
married, there followed 21 years in Chicago, where
he ultimately became Curator of Botany at the
Field Museum. That institution, and his contact
with the famous botanist Paul Standley, provided
his introduction to the plants of Guatemala and
brought home to him just how little we knew about
the plants of the American tropics. Missouri's flow-
ers remained his favorites, however, and he cul-
tivated them lovingly, with his wife Cora, in their
own wildflower garden near Chicago, a sanctuary
now maintained by The Nature Conservancy. For
30 years Cora and Julian crisscrossed Missouri
searching for plants, driving thousands of miles
back and forth from their home, camping in riv-
erbottoms, by dusty roadsides, or in forests, so that
they would come to know more fully the detailed
distributions and characteristics of the plants o
this state. Their cultivation of many of these plants
in their home garden was not merely a scholarly
exercise; it was also an act of love, a celebration
of their natural beauty and their individual char-
acter, as anyone who has turned the pages of
Julian’s exemplary 1963 Flora of Missouri will
now. What memories those explorations provided
Julian and Cora, and what times they shared to-
gether! To know about some of them, read Cora's
Behind the Scenes, a testimony to the beauties of
our state and the joy that is in store for those who
take the time to appreciate, understand, and enjoy
them. Cora wrote:
The morning was cold and clear. Pine trees and
shrubs, gray and bent with ice and snow, lent variety
to the icicled oaks. At the top of the hill we came
upon the sunrise. The whole view for miles across
the hills was a pinos blaze of crystalline purity.
Against the sun, the tops of trees turned to polished
gold, dadag i to silvered lower limbs rising above a

proved a rewarding one, and Julian went on to add
more to our knowledge of the plants of Venezuela
than anyone had before. A quarter of a century
was enough—filled with friends from Venezuela,
new friends from the States, wonderful new plants,
many of them extravagantly beautiful, and hundreds
named in Julian’s honor, hundreds of them. After
Cora’s death, Julian came back here to his home-
town and began to write in earnest about the in-
credible plants of the Lost World. His last work
will be completed here, and will stand as a final
testament to his industry and to his scholarship.
As for any human being, however, what will prove
to be even more important to all of us will be our
memories, for Julian Steyermark was an inspira-
tional person, one who projected his own values
without trumpeting them, and thereby enriched all
our lives, as he did the literature of botany.
In concluding her book, Cora wrote:

We all toil in a common field, inspired by early

us, enrich our souls with their beauty, and inspire
our actions, we have found a common bond. Here

Steyermark Recollections 629
During the 1940s in my beginnings as a botanist,
I started to understand the importance of Dr. Jul
Steyermark's works on the taxonomy of the Vane
ezuelan flora. The National Herbarium already pos-
sessed numerous collections made by the remark-
able scientist. By the 1950s, our friendship had
grown stronger and lasted for more than 30 years.
His long and exhaustive research of the Venezuelan
geography created a major collection that has con-
tributed in a decisive way to enhance Venezuela's
floristic inventory.
His humility and generosity were the most out-
standing features of his personality. A few years
ago, before departing for Venezuela's Guayana, |
asked Julian to inform me on the area I was going
to visit, a place he knew and had explored. Among
the helpful and valuable facts he supplied was the
name of a man who knew the region well and could
act as a “baqueano” [guide]. Arriving in the area,
I found the person Julian had mentioned. I told
him my mission in the area and that Dr. Steyermark
had recommended him to me. To my suprise he
“Mr. Steyermark? I have never heard
> However, I insisted and slowly re-
answered,
such a name.’
peated, “Are you sure you don’t know Dr. Julian
Steyermark?" His facial expression suddenly
changed and he replied smiling, you mean
Julian, of course I know him and I am ready to
help you."
This story helps to illustrate Julian's sense of
humility, generosity, and harmony. His legacy as
a scientist goes hand in hand with the personal
attributes that made him a great human being and
a beloved friend to those who knew him.— Leandro
Aristeguieta, Universidad Central de Venezuela,
Jardín Botánico de Caracas.
When I arrived at the Instituto Botánico in
Caracas in the summer of 1975 looking for a
project to help me learn about tropical plants, I
was brought into the office of one very busy, grum
Dr. Julian Steyermark. Faced with a botanical neo-
phyte, he suggested that I begin collecting plants
from the hills surrounding the Instituto—a patc
of secondary, deciduous forest in the heart of the
city. Years later this project led to a paper we
published together on the vegetation of the decid-
uous forests of Caracas, but only after many jour-
neys in each other's company to the few wooded
areas near the city not yet overtaken by apartment
buildings or “ranchos.” Following up our finding
of five species of the coca genus, Erythroxylum,
growing side by side in the hills above the Botanical
Garden, a student of mine at Simón Bolivar Uni-
versity in Caracas completed a wonderful thesis on

the comparative reproductive biology of the group.
Another result of our study was the recognition of
two species new to science, Eugenia mcvaughii
and Erythroxylum undulatum, both based on plants
found less than 100 meters from the front door
of the Instituto. It was the shortest trip I know of
for specimens to be placed in the type collection
of the National Herbarium.
Now years later I sit in Julian's former office—
sometimes in his chair, picking up where he had
left his unfinished project, the Flora of the Ven-
ezuelan Guayana, more "iren known as
the “Flora of the Lost World.” Julian was a *'ba-
queano” (guide, in sas to me, for he opened
up many paths that I was to follow.

by car from the city of Loja; he got there by foot
and mule, on a fortnight trek through endless rains,
in October of 1943. His Fuchsia is a most unusual
species, with needlelike leaves, and if it survives
in cultivation it will be highly esteemed.
Many simple folk all over Venezuela knew and
remembered Julian. I met some of them, usually
in remote places, like “Horacio,” a Makiritare
Indian who spoke no Spanish but had climbed many
a tree for him; and José Mendoza, an Andean
homesteader from San Vicente de la Revancha,
whose senile father had guided Julian years ago
far into the páramos towering over the valley. Both
reacted similarly when I mentioned Julian's name:
a big, amused grin accompanied by signs of respect
for a man so dedicated to his botanical mission. —
Paul E. Berry, Missouri Botanical Garden.
I had been at the New York Botanical Garden
as a doctoral student for all of three weeks in 1980
when I first met Julian Steyermark. He was visiting
the New York Botanical Garden to consult our
Guayana Highland collections and to collaborate
with Bassett Maguire on several taxonomic treat-
ments. Of course, I already knew of him by rep-
utation. | was a novice to tropical botany, so in an
attempt to say something intelligent to him I dug
back into my M.S. thesis on /soetes and located
the citation of Steyermark 85179, which I had
identified as /. melanopoda Gay & Dur. | reported
this to Julian, and to my amazement he immediately
told me where in Missouri the specimen had come
from and the month during which he collected it
23 years previously! This was not to be the last
time over the following eight years years that Ju-
lian's prodigious memory would impress me.
| also became aware of Julian's capacity for
work as I observed him during his subsequent per-
iodic visits to New York. Occasionally, he would
share my office because of our mutual interests in
the Guayana Highland flora. He stayed in the Gar-
den's Snuff Mill apartment during his visits. By
7:30 A.M. he would be at the herbarium. With a
single-mindedness he worked on specimens until
about 6:00 P.M. with only a half-hour break at the
lunch table. Julian was not one for idle chat, and
he clearly did not like to be disturbed while working.
At six, and also with a single-mindedness, he would
round up any remaining staff and students and go
have a huge dinner, followed always by a stop at
the local ice cream establishment. Occasionally, he
would take in a movie, but more often than not he
would head back to the herbarium for several more
hours of work before retiring for the night.
And thus, day after day, he would make his way
through huge piles of specimens, writing descrip-
tions of new taxa on the spot in his nearly illegible
scrawl. Julian confessed that he “over-described””
occasionally, and that perhaps he split excessively.
lowever, he justified it by saying that he viewed
his role as one of describing biotic diversity as he
saw it. He would leave it to following generations
of botanists to determine just how “good” his de-
cisions were. How history will judge his taxonomic
decisions does remain to be seen, but there can be
no doubt that Julian had an excellent "eye" for
I also know that I trust his
specimen annotations more than those by just about
seeing differences.
anybody else. During the first half of this century,
when a researcher needed quick, reliable deter-
minations for neotropical specimens, the solution
was "send them to Standley." Julian was heir to
this role. His magnum opus, Flora of the Vene-
zuelan Guayana, will aptly attest to his unparal-
leled knowledge of the neotropical flora. In an age
of few heroes, Julian was one for many of us.—

Hace cuatro anos, el 7 de junio de 1984, tuve
el honor de darle con alegria y en nombre de los
botánicos de Venezuela, un adiós, un hasta luego,
a Julian Steyermark. Esta despedida era transito-
ria, ya que por su propia decisión, volvia a su tierra
natal, Saint Louis, Missouri. A pesar de su ida,
Julian no podia resistir la tentación de permanecer
mucho tiempo allà, solo en el norte, razón por la
cual, con frecuencia hasta principios de este ano,
regresaba a Venezuela, pues como el decia: amor
a primera vista," fue su reacción al ver por vez
primera a este pais en 1943. Y, cual enamorado,
exclamó: “Mi amor a Venezuela, se debe no solo
a sus flores, a su fauna, a sus paisajes, sino tambien
a mis amigos quienes poseen una alta sensibilidad,
capacidad, y deseo de trabajar en la botánica y en
la conservación de sus recursos naturales. Por eso
mi amor por Venezuela fue instantáneo.”

Julian llegó a Venezuela en diciembre de 1943,
cuando en misión del gobierno de su patria de
vino a buscar la corteza del árbol de la
Mundial para combatir el paludismo. Sus primeras
incursiones botáncas en el pais las efectuó en lo
que es hoy el Parque Nacional El Avila, de alli
pasó al Oriente de nuestro territorio, regresando a
Estados Unidos en 1945 con una colección de
8,000 muestras botánicas.
La belleza escénica de los diferentes ambientes
venezolanos, el contacto con las plantas, coló tan
hondo en la sencilla humanidad de Julian, que
sonaba que Venezuela debería ser su pais. Este
sueño, cual regalo de navidad, se convirtió en
realidad cuando en diciembre de 1959 recibió la
invitación de Tobias Lasser, por recomendación de
William H. Phelps, para que formara parte del
personal del Herbario Nacional de Venezuela, donde
permaneció activamente como estudioso de la flora
Venezolana. Por su larga trayectoria y aportes al
conocimiento floristico del pais recibió entre otras
las siguientes distinciones: Orden Andrés Bello

I first met Julian Steyermark 60 years ago. He
was painting an orchid in the old Floral Display
House of the Missouri Botanical Garden during the
annual orchid show. At that time he was an un-
dergraduate student at Washington University.
Later Julian became chairman of the botany
group of the Webster Groves Nature Study Society.
He wrote articles for Nature Notes, which is the
monthly publication of the society. He also spoke
at the meetings and led botany group field trips to
local areas.
Since Julian didn't have the use of an automobile
while he was a student at Washington University,
he depended on his friends to take him to areas
that he couldn't reach by streetcars or trains. He

and identifying plants, he did take some time off
to play tennis at Tower Grove Park. Also he at-
tended some of the Webster Groves Nature Study
Society's parties.
On the day that Julian received his Ph.D. degree
from the Henry Shaw School of Botany of Wash-
ington University in 1933, I happened to meet
him with his parents at the Missouri Botanical
Garden. He couldn't stay away from the garden
that meant so much to him, even on his graduation
day.— Arthur Christ, St. Louis, Missouri; from
Julian Steyermark's memorial service.
I am very sad with the passing of Julian, a
taxonomist extraordinaire and a dear personal
friend. I feel very privileged to have known him
closely during the last two decades of his life. Julian
was truly one of the greats in his field and his
contributions to taxonomy, exploration, collecting,
and conservation will long be remembered and rec-
ognized— and use
Of all the people I have known personally, he,
perhaps as well as anyone, exemplified a person of
whom it can be said without any exaggeration that
his vocation was also his avocation. I will, above
all else, remember him as a person totally devoted
to his work and one for whom his work held a
never-ending fascination.
I would like to recall several personal experi-
ences and incidents that illustrate some aspects of
his personality and career.
first got to know Julian personally in 1971,
when as a graduate student | went to Venezuela
to study and collect plants for my thesis. I was
already well aware of his many accomplishments
and his international reputation. As with almost
any other novice going to a foreign country to
collect, I was having difficulties in making the nec-
essary arrangements. With some trepidation, I
asked for his help, and I was very grateful that he
took time to arrange contacts that made my work
much easier.
I later learned that he guarded his time very
jealously, surely a necessity for someone who re-
ceived little secretarial help at the time, who pub-
lished thousands of pages, and who was unrivaled
as a plant collector. However, if you were serious
about plant collecting, he would often try to help.
He was very well aware that the next 20 or 30
years might be the last chance for any of us to
study and collect the undisturbed vegetation in
many areas of Venezuela that had never been bo-
tanically surveyed, and he always felt only a small
portion of the country had been adequately sur-
veye
After I joined the Missouri Botanical Garden in
1972, a number of other staff members, including
Tom Croat and Al Gentry, collected in Venezuela,
and we seemed to pass muster as plant collectors
since Julian proposed in 1975 that the Garden and
the Instituto Botanico organize a cooperative pro-
gram of joint expeditions to areas in which the
vegetation was being severely damage
fter we secured funds for this work, Julian and
I made a number of field trips together, and it was
then that I really got to know him well.
Julian was a very goal-oriented person who
doggedly pursued his objectives until they were
accomplished, whether it concerned writing the
Flora of Missouri during his free time or whether
it concerned collecting plants from a tepui never
before explored.
en he went to the Field Museum in 1937,
he had already collected over 25,000 plants. There
he worked under and was greatly influenced by
another of the great plant collectors, Paul Standley,
who was to collect well over 100,000 numbers by
the end of his own career. Julian early on, as he
told me early during our association, determined
in his own mind that he would eventually surpass
Standley’s numbers, and he
ven on a daily basis, a had Standley
before him— would set a goal of a certain number
of collections to be made that day, and he would
challenge his companions to do the same. He would
invariably have a very precise recall of what he
collected each day, and he loved to challenge you
to guess the totals gained by each person, spicing
the proceedings by betting a milkshake on who
could guess the closest. I soon learned to keep
closer track of what I was collecting!
Although Julian was a modest person who lived
a quiet, simple life, he, like all of us, appreciated
recognition. After several years of working togeth-
er, I knew that he was proud of the large number
of plants he had collected, and I began to think of
ways in which this collecting record might become
more widely recognized.
I finally hit upon the idea of nominating him as
a champion plant collector to the Guinness Book
of World Records. Because I was a bit uneasy that
he might consider this a trivialization of his accom-
plishments, I checked out the idea with him be-
forehand, and he approved. Unfortunately, it took
the editors of Guinness several years to decide
what plant collecting was all about and whether it
really had a place in their book. In the meantime,
Julian would ask me every time I came to Vene-
zuela what had happened to this proposal, and |
had to tell him to be patient, that it was still in the
Annals of the
Missouri Botanical Garden
works. The record was finally included in the 1986
edition, and Julian seemed to enjoy the additional
attention it brought him from the popular media.
I earlier mentioned that Pll always remember
Julian as a person totally devoted to his work. This
perception comes from watching him put in long
hours of fiercely concentrated work each day, sev-
en days per week, and 52 weeks per year, but it
was also brought home to me in a much more
amusing way on our first trip together in 1978.
Our objective on that trip was to collect in a
small range of mountains known as the Cerros de
Bachiller in the Coastal Cordillera of northern Ven-
ezuela, where new agricultural developments seemed
certain to destroy much of the virgin vegetation
in the near future. Close to a small mountain stream
at the foot of the mountains, we had constructed
a nice base camp, from which we collected every
day. As was customary, we slept in hammocks
strung beneath a plastic sheet to keep out the rain.
Julian would always wake just before dawn, and as
we were getting ready for the day's collecting, he
would tell me his dreams of the night before. Every
morning during the two weeks of that trip, the
dream he recalled would be enjoyable and botan-
Their s e "Lost
World," and he would discover the most ailing
ical. setting would often be in t
new plants, which often combined bizarre char-
acters from several families, so that he would be
very puzzled and strongly challenged on how to
interpret these strange plants. After a couple of
days of this, I began to think to myself, here is an
even more devoted man than I had realized, not
only does he devote most of his working hours to
botany, but even his sleeping hours are devoted to
it.
So these are some of the ways Pll always re-
member Julian, a valued friend, a man of great
accomplishments, a man truly devoted to the good
things of this world, and one who leaves an enor-
mous legacy to us all.— Gerrit Davidse, Missouri
Botanical Garden; from Julian Steyermark's me-
morial service.
Omnia fluerit. Everything flows. Fifty-five years
ago Julian Steyermark, then 24, and taking his
Ph.D. here, wrote to me in the spring of 1933—
I was at UCLA
of Grindelia collections that I had made, gum-
at the time—asking for the loan
weeds of the Compositae (as we called them then).
On June 21st he wrote again, that the loan was
being returned and added that he was tending a
34-acre plot of grindelias, and rushing his getting
a Ph.D. He wrote, “I shall be starting off soon on
a 2 or 3 weeks botanical expedition into unexplored
parts botanically of Missouri, getting into many
remote sections." Some readers may wonder when
Julian really began botanizing: on October 13th,
1930, he collected Grindelia lanceolata along the
railroad tracks bordering the Washington Univer-
sity campus. That collection was numbered 1506.
By September 11, 1932 he had numbered to 7/64,
or 5,658 field numbers in less than two years.
Now and then I encountered Julian at the Gray
Herbarium or the New York Botanical Garden.
Then, with deep pleasure, I came here in 1986 to
work in the library, as Julian before me had come
to forage in the hortus siccus, the dry garden. In
researching the vismias and the shrubby gentians,
I came to know Julian's detailed collections and
his keen interest in plant geography and those
“unexplored parts botanically”
their specimens you shall know them!— so true of
letter of 1933:
**One derives the chief or almost the chief pleasure
of Venezuela. By
botanists. Let me return to Julian's
from studying plants in their natural habitat, ex-
ploring for them in remote places which add to the
zest and thrill of discovery. At least I have always
felt that way and most field naturalists hold similar
opinions." The tepuis used to be called the "Lost
World" but that was before Julian. Omnia fleu-
rit.— Joseph Ewan, Missouri Botanical Garden;
from Julian Steyermark's memorial service.
My introduction to Julian Steyermark was
through the Flora of Guatemala while working as
a Peace Corps volunteer in Honduras on a floristic
survey of one of the central valleys. Honduras does
not have any written flora, so the next best thing
was the Flora of Guatemala of which many vol-
umes were written by Standley and Steyermark.
Filled with useful information, excellent keys, and
descriptions, it taught me a great deal about trop-
ical botany. When I was finally preparing to leave

When 1 finally made it here some months later
and luckily was able to get a job, I was told that
Julian Steyermark had just come up from Vene-
zuela and was on the staff! One of the first things
that I wanted to do was meet him, and you can
imagine my surprise and pleasure upon learning
that I was going to be working for him, and how
much even more surprised I was when three months
later | was in Venezuela on a major expedition to
the Lost World!
It was a real thrill and a tremendous learning
experience to work in the field with Julian. He had

an "eagle eye" for spotting plants and if you didn't
see something that he did, he would let you know
it. When I first went out on my own to collect
some specimens I found a beautiful plant that I
thought was very unusual; it had large bright red
bracts surrounding a dense cluster of flowers. When
I returned to camp, I pulled it out of my collecting
bag with pride to show him. But when he saw it,
he took it from me in disgust and threw it to the
ground, saying sternly “this is Psychotria poep-
pigiana subsp. barcellana, one of the most com-
mon and weedy plants of South America, don't
ever collect it again." I was a little bit embarrassed,
so the next day I made even more of an effort and
risked my neck to get up on some diffici
bluffs. When I got back to camp, I sheepishly pulled
another member of the same family out of the bag
lt sandstone
to show him. This time, however, he looked at it
with a great deal more interest, a puzzled look
came over his face, and he admitted that he didn't
know what it was, and that it likely
something new. From then on I learned that when-
ever he gave that look at a plant, it meant some-
thing interesting had turned up. In this particular
case it was a genus of the coffee family new for
was very
science.
Fieldwork was very special for Julian—rather
than “vacations,” he went on field trips. It was
impossible not to be caught up by his enthusiasm
for collecting plants. He always likened collecting
to a “treasure hunt." Even with his two artificial
hips, he would plow through brush, crawl over and
under logs, fall down, laugh about it, and push on.
He truly liked collecting all kinds of plants, but I
think that the Bromeliaceae were his favorite fam-
Julian was involved in the first helicopter ex-
pedition in Venezuela, which took place in 1967
to the isolated Cerro Jaua. He quickly realized the
advantages of that mode of transportation and found
that it would increase even his amazing productiv-
ity. He would use it frequently in the following
years to get to some of the most inaccessible of
the Lost World summits. To think that in all the
years prior, when he made so many of his famous
expeditions to some of the most remote areas in
the country, that everything was by foot, including
long and hazardous climbs to the tops of several
of the more prominent tepuis, such as Chimantá
and Auyan-tepui. Once I understood the complex-
ities involved in these huge expeditions back then,
my admiration for him increased even more.
e was a great friend to the Indians of the
region. They enjoyed his sense of humor and spirit
of adventure. He is somewhat famous in certain
Indian tribes. Two years ago, when we were plan-
ning a trip to a series of unexplored mountains in
the heart of the Lost World, we were surprised to
be met by the son and grandsons of an Indian who
had worked with Julian back in the 1940s. They

had heard that **Hulian Esteyermark" was to be
back in the area, and were eager to volunteer their
help.
On a personal side, it took a while to get to
know him, and he did have some unusual ways.
I thought that he was kidding when he told me
about his liking for rock & roll music until he
showed me his more than 800 records ranging
from Elvis Presley to the Rolling Stones. He also
loved Venezuelan and Andean folk music.
— He loved to bet milkshakes on whether his friends
could identify a plant or not. I paid out my fair
share to him and to Ron Liesner (an expert at plant
family identifications).
-He would eat sparingly for breakfast or lunch,
but there were few who could match him at the
dinner table. Buffets at nice restaurants were his
favorite, and he would go back time after time
before he was ready for dessert.
—Other than fancy buffets, he thrived on fruits,
vegetables, and ice cream and was a great exper-
imenter with native edibles. Flower fragrances were
we would have contests in the
field to see who could find the most fragrant flower,
irresistible to him;
and he smelled every one with great pleasure.
— Swimming was a favorite pastime of his. The
only time that he would take off from the herbarium
or field (or let any of his assistants do so) was to
go to the beach. He loved floating in the waves
and would do so for hours at a time.
Julian was a most ardent and effective conser-
vationist. He worked hard in Venezuela through
the National Park Service to protect the forests in
the North that were, and still are, rapidly being
destroyed, and was instrumental in identifying many
protection. In late
88, we were told that the President of Venezuela
areas in the South worthy o
was signing into legislation a new National Park in
the delta of the Orinoco River. It was planned with
Julian's help.
Finally, I would like to share some parts of a
letter that was sent to Julian a few weeks ago that
illustrates his impact upon others around him, not
just as a botanist, but as a person who could inspire
others:

City High School during the 1937-38 period at the
time E K to your leaving for the Field Museum

ae e as a teacher and as a ou provide
a great ia model for a i anali interested in sci-
ence. And | remember how impressed I was with the
fact that my teacher was leaving to become Curator
of a portion of the famous Field Museum. You and
several of the other faculty members at U. City H
provided great inspiration to accomplish at that point
in my life. Thanks.
Fifty years later, another student of his feels the
same way.
I am deeply saddened to lose a great friend and
a teacher. I will never forget him and what he has
done for botany, for conservation, and for me.—
Bruce K. Holst, Missouri Botanical Garden; from
Julian Steyermark's memorial service.
The expression on his face was rather eloquent
when Julian saw the pile of newspapers that I had
put in front of him on his desk. He knew that |
was an ecologist starting to do research in the cloud
forests of Rancho Grande, in National Park Henri
Pittier some 100 km west of Caracas. My "bo-
tanical collections" consisted mainly of large,
labeled leaves pressed between five or even ten
sheets of newspaper in order to assure their
drying. “What am I supposed to do with this?"
Julian asked me impatiently. “Well, I think that
you can identify them," I answered a little bit
scare fter a few silent minutes, during which
Julian lane ed through the "specimens," he re-
turned the pile to me and said, shaking his head,
“These specimens are unidentifiable, they are all
sterile; there is nothing I can do with them.” And
with these words he continued typing labels on his
old OLIVETTI typewriter, and I suspected that | had
done something wron
After this episode, vids h occurred sometime in
early 1974 in Julian's office at the Instituto Bo-
tánico in Caracas, | realized that plant collecting
in a tropical cloud forest was rather different from
what I had done before on a very limited scale in
the Mediterranean macchia of southern ltaly or
the island of Sardinia. Under Dr. Steyermark's
guidance I learned how to make proper plant col-
lections and how to identify them to family, genus,
or even species. I soon realized, too, how fortunate
I was to have such an outstanding teacher: every
passing day | was increasingly impressed by the
astonishing taxonomic knowledge of this man, who
seemed to be omniscient and blessed with a re-
markable memory of the most complicated plant
mes!
After having been invited to my first chili con
carne at Julian's home (his favorite dish expertly
prepared by his wife Cora),

had improved the quality of my botanical speci-
mens. À couple of vears later, we engaged in a
our relationship
joint venture, resulting in the publication of the

Steyermark Recollections
Flora del Avila. Julian wrote most of the keys of
that book at home while recovering from his two
hip operations and while I was in Austria concluding
my Ph.D. thesis. At my return to Venezuela in
September 1976, we then had a rather hard time
finishing the rest of the manuscript (some 1,600
pages), since my Tyrolean stubbornness was not less
persistent than Julian's Missouri stubbornness! This
ook, however, constituted a tremendous experi-
ence for me, and since then we had become col-
leagues, working together very closely in the In-
stituto Botánico. From then on, Julian was always
anxious to be the first to see my collections from
the Venezuelan Amazonas and later from the many
tepuis of the Guayana Highlands.
In 1982 we decided to start another new project
titled Flora and Vegetation of the Venezuelan
Guayana. We realized that such an enterprise
would take years of most intensive work, but we
both decided to dedicate all our efforts and re-
sources to that project. Although destiny later di-
vided our paths, Julian and his collaborators have
advanced relentlessly towards completion of that
flora, whereas I have continued to contribute by
collecting interesting plants from the many places
visited during my ecological and phytogeographical
fieldwork in that region.
It was a great satisfaction for me to invite Julian
to an expedition into the Chimanta massif, one of
the richest Guayana mountains, where he and John
Wurdack had done such pioneering botanical ex-
ploration in 1953 and 1958. When we established
camp near a huge colony of Chimantaea mirabilis,
a most striking member of the Compositae discov-
ered by him in 1953, Julian could not hide the
emotion caused by this reencounter after 25 years!
And then, there he was, the " Julian Stey-
ermark, sitting at his camping table labs and
pressing plants and plants and plants,
amazingly numerous plants every night (at that
time he was at his number 128,000). And every
two minutes he would call me and exhibit another
exciting find, or explain another variation or another
novelty. One year later we would be again on the
same mountain and discover a new genus (4co-
panea in the Theaceae), and then get flooded at
our camp at 2 o'clock in the morning with icy
water half a meter deep from the nearby cano!
Julian Alfred Steyermark, the great botanical
explorer of the Guayana and many other places of
the Venezuelan country, has now left us, but his
memories, as numerous as his botanical collections,
will always accompany us from tepui to tepui, to-
gether with the gratitude of having had the privilege
to be one of his students!— Otto Huber, Caracas,
Venezuela.
I first heard of Julian Steyermark when I was
a student at the University of Wisconsin. Dr. Hug
Iltis said he wanted to prepare a flora of Wisconsin
that was as good as Steyermark's Flora of Mis-
souri. Julian enjoyed hearing that.
I first met Julian when I went to Venezuela in
1977 as part of the joint Missouri Botanical Garden
and Herbario Nacional de Venezuela project spon-
sored by NSF and CONOCIT. When I arrived,
Julian was skeptical and concerned and told me
about the difficult conditions: rain, heat,
snakes, and other perils. Julian, Francisco Delascio,
and I went to the Delta Amacuro (delta of the
Orinoco River) for a month. The collecting and the
trip were exciting and one was able to ignore the
difficult conditions. I quickly learned Julian was
very good at spotting plants to collect. He first
started using clippers when he saw me using them
and we sometimes joked that he learned to collect
plants from me (he had 114,000 collections when
we met)
Numerous field trips with Julian were a privilege.
I learned many plants from him and how to find
specimens to collect. We frequently bet a milk-
shake if we thought we could catch the other person
not knowing a plant to family. Even a sterile plant
was game if that person collected it. Usually I could
catch him only if it was a genus that was unusual
for the family and the genus was new for Venezuela.
We also bet milkshakes for guessing how many
plants we had collected before we pressed and
numbered them. I, also he, sometimes would collect
numerous extra mosses so the competitor's guess
would be too low. Once, after Julian had guessed
right three days in a row, he stated his guess aiming
at a fourth win, then I guessed one lower, and
Ángel González guessed one higher. Julian had to
do something else. Ángel and I pressed the plants
and wrote the field notes. It came out to Julian's
number! Ángel and I decided to trick him. One
species of herb had both flowering and fruiting
individuals. We split them into different collection
numbers. But Julian had the last laugh. Not only
were they different species, they were different
genera! We also guessed at arrival times for a
milkshake. Cora, Julian's wife, said they had bet
ice-cream cones when they did fieldwork in Mis-
insects,
ouri.
Julian loved to try different restaurants and go
to the movies, and many of his friends enjoyed
going with him. For a long time, Julian was my
closest friend. Julian had a good sense of humor
and it was fun to tease him. But it did annoy him
when I said I was from Missouri and to show me.
Gerrit Davidse did the same. For a long time he
idn't consider us Missourians.
un
638

Missouri Botanical Garden
e often corrected my Spanish. I sometimes
joked that Julian taught me Spanish. He vehe-
mently denied it, but everyone else liked it.
When he came to Missouri, he had to get his
driver's license, and I had to teach him to drive
my car. Later, I joked I had taught him how to
drive. He would mention the first two things the
driving examiner asked were the lights and horn,
and I hadn't shown him those.
Julian claimed that he had shaved every morning
since the thirties. We could be short of water and
he would still shave. He, Bruce Holst, and I were
almost stranded on top of a tepui without our things.
Bruce and I kidded him that we would see him
unshaved. But then we decided he would shave
with his machete. The helicopter came so we didn't
find out.
Julian and I were in some very risky, potentially
dangerous places in collecting. But the most wor-
ried and most concerned I ever saw him was when
we arrived back in Caracas and he couldn't find
his hairpiece. It frustrated him when women saw
him without his hairpiece the first time in the field
and told him they thought he looked better without
When we were stranded on Cerro Duida, wet,
with no shelter or supplies, in a potentially fatal
situation, Julian joked about dying on a tepui. We
assured him that was fine as long as it was some
other tepui.
In the field Julian often remembered collecting
the same rare species 30 years previously. An
amazing number of species were either described
him or named after him. I wonder what level
Venezuelan botany would be at if it were not for
Julian. He worked fast, long hours, and accurately.
One could go many places in Venezuela and
local people would remember Julian when he was
there 20 to 40 years previously.
Identifying specimens, I worked on many dif-
ferent plant groups. Julian was a good friend be-
cause I could talk about many different groups and
he had worked on them also.
For quite a while when I ran into a problem
with a plant group or if I had a plant I couldn't
identify to family, my first reaction was still to go
ask Julian, only to remember Julian was no longer
here.— Ronald Liesner, Missouri Botanical Gar-
den.
I first met Julian Steyermark in October, 1963,
at a difficult time in my life, and I am proud to
say that since that time, he has helped me more
than anyone else.
At that time I was an unemployed and com-
pletely frustrated young man 24 years old; and
just “to kill time," I decided to draw flowers. So
I began to go around with some paper and a box
of color pencils, and devoted myself to drawing
flowers in Caracas near where I lived in a student
dormitory. After a month or so, I had checked all
the gardens, houses, and whatever natural vege-
tation there was around and had exhausted inter-
esting subjects for drawing and so expanded into
surrounding neighborhoods, eventually reaching the
Botanical Garden of Caracas, where there was a
large variety of exotic and beautiful flowers.
remember that one day, while concentrating
on trying to reproduce the colors of a
paradise" flower (Strelitzia reginae), a man came
up to look at my work. I had seen him occasionally
on previous days, but we never had spoken to each
other. He was August Braun, the head gardener.
After exchanging some comments, he told me that
there was no artist at the Botanical Garden, since
the former artist (the late Mr. Ebersteins) had
retired four months earlier; and he suggested that
I show my drawings to Dr. Lasser, the director.
The following day I took some of my best draw-
ings and showed them to Dr. Lasser. He liked them
but said that drawings needed for scientific publi-
cations had to be more “objective” and made with
black india ink. As I had no experience with that
kind of drawing, he introduced me to Dr. Julian
Steyermark and asked him to give me some ori-
entation. So | met the man, and got the job!
After I had gained some confidence, in 1963
Julian asked me to draw a new species that he was
describing, Palicourea chimo, and 1 complained
that I had only herbarium specimens, not live plants.
Julian, who also began his botanical career as an
artist, understood and helped me look for a solution
and invited me along on a trip to Naiguata, on the
northern side of the coastal mountain range of
Venezuela, where he had not been before. The
Palicourea was encountered and drawn fresh.
On the two-day expedition we found a new
species, which Julian named Heisteria olivae (later
placed into the synonymy of H. latifolia) to honor
our guide, the young architect Francisco Oliva
Esteva [see recollections in this volume J.
Julian was so impressed by the rich vegetation
there that two weeks later we went back to explore
further. As Julian had begun his botanical activity
in Venezuela in search of quinine plants and was
an adviser to a large drug company in the U.S.,
he was always interested in potentially useful plants
as suppliers of drugs. On our second expedition to
Volume 76, Number 3
1989
Steyermark Recollections 639
the coastal range, we found a big Lacmellea tree,
called **vaco negro" (black cow) by our guide, who
stated that its sweet, milky sap was used as a
remedy for asthma. Since we found only flowers
and fruits on the ground, Julian felt frustrated, but
I returned a few weeks later, climbed the tree using
and collected several complete
specimens. I illustrated these, and Julian named
Lacmellea costanensis as a new species.
So delighted was Julian with the scenery of those
slopes facing the sea, completely carpeted by virgin
a liana
cloud forests, that he soon made yet another ex-
pedition there. On this third trip, we went with Mr.
G. . Dunsterville, the great orchid artist, and
his wife. Nora. Cora Steyermark also came with
us, but, as she was suffering from some bad health
and could not match our pace, Julian went ahead
with a bunch of yellow and red woolen threads,
dropping them from time to time along the trail
for her to follow. So, late in the afternoon, Cora
reached us bright with joy and carrying all the
threads she picked up along the trail.
n this same trip, Victoriano Carreno Espinoza
joined us. Julian had met him a month earlier on
a previous expedition to Cerro Humo in the eastern
peninsula of Paria. He was so satisfied with Victor’s
knowledge of plants, skill, and enthusiasm, that
Julian brought him to Caracas and helped him get
a job in horticulture at the Central University.
Victor continued to work with Julian and quickly
became his faithful and efficient assistant on many
expeditions throughout Venezuela during a fifteen-
year period.
When I met Julian, he was living in an apartment
complex called **Residencias Magnolia" located in
Los Palos Grandes, Caracas. The apartment had
a terrace where he kept plants that he brought
back from his botanical expeditions. He would lead
visitors on a ritual tour around the garden to give
an explanation of the plant names and the regions
they came from, with considerations about their
color, shape, or scent. But, Julian's expeditions
were so frequent and fruitful that the apartment's
terrace became too crowded, and about 1971 he
moved to the suburb of Santa Eduvigis. There he
had more room to display his plants and on the
back side of the house he created a miniature jungle
under a mango tree. In some cases Julian collected
sterile plants, which he brought home until they
flowered and then made herbarium specimens from
m.
Besides the small garden space, noise from traf-
fic, and the fact that their house was broken into
bothered Julian and Cora, so in mid-1975 they
found a new house in the neighborhood of Santa
Fe Sur. They were particularly pleased with it,
because from it they enjoyed a complete view of
Avila National Park across the Caracas Valley,
and it was close to a place officially listed as a
“green area," where supposedly no other buildings
could be built. But several months later, in spite
of all the official statements, construction began
on a huge apartment complex whose wall reached
right up to the Steyermark's garden. He felt very
frustrated, and in his field book he remarked sadly,
“Nov. 20, 1975. Destruction of green area back
of our home."
Yet the new house still had room for gardening,
and the Steyermarks displayed the beautiful col-
lection of bromeliads on the porch and put the
aroids, orchids, begonias, peperomias, and ferns
under a plastic net. In the center, there was a
planter of red roses, surrounded by several Hip-
peastrum lilies, and another plant of rosemary
surrounded by the thorny Euphorbia splendens.
In back, towards the new apartment complex's
wall, there was a Chrysalidocarpus lutescens palm,
a Tibouchina semidecandra with big purple flow-
ers, a Mussaenda erythrophylla, a healthy Clusia
minor with waxy rose flowers, a terrestrial Cyr-
topodium orchid, and other miscellaneous herbs.
On the right side, climbing on the fence was Aris-
tolochia ringens, Heliconia caribaea, Nicolaia
elatior, and Lafoensia with white flowers pollinated
by bats. In a pot, there was also a “lily of the
valley" with very fragrant white flowers n Julian
especially enjoyed. On the side of the garden close
to the porch grew a row of [ris confusa that never
bloomed. Once a month, Victor went to the house
to cut the grass and clean the garden.
Cora, a member of the Audubon Society, en-
joyed observing birds, and every day would put
bananas and oranges in a feeder to attract them
to the garden, and sugar water for the humming-
birds. She kept a diary of the garden and recorded
the exact date of blooming for every plant, days
of rain and sun, and other data for the garden's
management. She was also one of the founders of
a garden club, which in 1973 created a scented
garden for the blind along the avenue Rómulo
Gallegos in Caracas.
On many occasions Julian would honor me with
an invitation to dine in his house, where I thor-
oughly enjoyed Cora's excellent cooking, especially
the pies and brownies. Sometimes when we came
back late at night from some expedition, he invited
me to sleep in their house in the guest room. The
following day, of course, I would get a delicious

breakfast. | remember that when we sat at the At that time Julian was preparing a monograph
breakfast table, Julian and Cora would recount the
dreams they had the night before.
On a trip to Puerto Cabello in 1973 with Julian
and Victor, I found out that Julian had a love for
snakes. We walked along an old canal breached
in areas and useless due to many rocks and earth
that had fallen into it;
little waterfall, it was full of clear and fresh water.
Julian, who loved to drink from sparkling streams,
put his right hand on the edge of th
bent over to take a drink (with the left he was
holding the plant press). When he finished drinking,
and before he stood up, he spotted a poisonous
snake out of the corner of his eye, a fer-de-lance
but in a corner, under a
e water and
(Bothrops atrox), just between his hand and his
cheek. Victor hurried there with the machete to
kill it, but Julian didn't let him; instead, he pushed
and chased the snake away into the high vegetation.
In 1983, Julian returned to that area again with
Paul Berry and me to gather specimens of Sela-
ginella gigantea, but the old trail was completely
lost. Paul and I managed to reach the Selaginella
site, but just as we arrived, a heavy thunderstorm
came up. Paul hurried to make a collection of the
rare Selaginella, and then we headed straight down
the mountain, since we lost our trail very quickly.
‘hen at last we reached Julian half an hour later,
the rain still falling, we found him sitting on his
press, trying to protect himself with a completely
wet piece of paper but he regained his spirits as
soon as he saw Paul's collection. All that area where
the Selaginella is found now belongs to the San
Estaban National Park, created in 1986 thanks to
Julian's enthusiastic report
In October 1970, Julian joined the Venezuelan
Brazilian Frontier Commission in a survey of the
Cerro de la Neblina, the highest mountain in the
Guayana, and he collected as intensely as ever.
While participating in that trip, the expeditionaries
were sent supplies from San Carlos de Rio Negro
(Venezuela) and Cocui (Brazil) by helicopter, so
Julian decided to send his first lot of collections
ahead to San Carlos, preserved in formol in plastic
bags; but, due to confusion, the plants were un-
loaded in Cocui. When Julian returned to Caracas,
he realized that a lot of his plants were missing, so
in March of the following year he sent me down
to San Carlos and Cocui to see if I could find the
lost collections and bring them back. When I met
the Brazilian officer in charge at Cocui, he told me
that he had been there only since January, and
that the soldiers, cleaning the warehouse, found a
lot of very bad-smelling plants and threw them into
the Rio Negro.
of the Rubiaceae for the Flora of Venezuela to
which I contributed as an artist, and in 1973, when
I received my degree at the Central University, I
resigned my job at the Botanical Garden and turned
to teaching. Julian complained about my decision
and told me that he had a lifelong dream to write
a flora of the Guayana, for which he would like to
employ me as the artist; but at that time I didn't
see how it would be possible. Anyway, I kept in
contact with him, and from time to time, on the
weekends or during vacation, he would invite me
to join him on some botanical expeditions, even
though at that time he was plagued by arthritis
of the hips. As Julian could not walk like he used
to, he needed extra help on his collecting trips.
In 1973 Julian was asked b
agency to make botanical surveys of several coastal
y a governmental
areas recently designated as national parks, and
he invited Victor and me along. We would rent a
boat for the day, and Victor and I would go out
with a bag and a machete and collect samples from
every plant we saw. Then, we would go back to
the boat, where Julian cleaned the specimens and
put them in his press. In the evening, we returned
to the hotel with the plants, and Julian, keeping
with his usual routine, worked for hours to number
the specimens and to make notes on habit, habitat,
and other peculiarities that he observed about the
living plants. On the following day when the em-
ployees went to clean the apartment, they would
complain loudly about the mess.
In February 1974, Julian joined the great ex-
pedition directed by Charles Brewer-Carias to ex-
plore the biggest sinkhole on top of Cerro Sarisa-
rinama in southern Venezuela. Victor went with
him since he was having difficulty walking at that
time. Even with the problems getting around, he
managed to collect more than 1,000 plants in 20
days, many of them rare, including 50 new to
science. From the bottom of the sinkhole, Charles
sent up a pretty little melastome with white flowers
and a shaded rose-colored ring around the calyx.
It turned out to be a new species that John Wur-
dack of the Smithsonian Institution named Phain-
antha steyermarkii. For his part, Julian felt so
satisfied and grateful with Victor's work, that he
named three new species for him: Psychotria car-
renoi, Phyllanthus carrenoi, and Sloanea car-
renoi.
During the several months before the expedition
to Sarisarinama, Julian had. been corresponding
with people who had had hip operations to correct
arthritis problems. They told him that they had felt
much better after the surgery, so at last he decided
Volume 76, Number 3

Steyermark Recollections
to undergo the operation. Since he had to be op-
erated on one side first, and then six months later
on the other side, he had to stay at home for a
whole year. But how was anybody going to convince
Julian to rest? That word was unknown to him,
and in fact I suspect he was afraid to rest. For
that reason, it did not surprise me that he soon
found a way to keep busy at home.
His good friend Otto Huber had been preparing
a list of all of the plants in the national herbarium
ever collected on the south slopes of Avila National
Park, the mountain that rises above the valley of
Caracas to the north. Since Otto was an ecologist,
he proposed to Julian that they coauthor a book
to be called the Flora of 4vila. Julian was fasci-
nated with the idea, but he insisted that the value
of such a flora would increase if it also covered the
less-explored northern slopes.
As he was recovering in a hospital room that
had a view of Avila high in front, he was inspired
to write the following phrase in the introduction to
the flora in reference to me fantastic view of the

tories.”
Surely when Julian planned the Flora of Avila
he had in mind the style of his huge and successful
work, Flora of Missouri. Since that was lavishly
illustrated, he wanted me to draw as many species
as possible in every plate, just like in his previous
work. He didn’t want to prepare a strictly scientific
work, but one that was usable by many different
people. One of the ways that he did this was to
insist that the publisher include a metric scale on
the back cover, with the hope that the flora would
be carried along up the mountain and used on the
spot to identify plants. A hopeful assumption, in-
deed, but one that demonstrated Julian’s interest
in making plants known and loved.
So, we began work on the Flora of Avila! I had
to make drawings from live material, and then bring
them back to Julian to be identified. As the work
progressed, he began to complain that I had too
many drawings of orchids and other showy plants
but few or nothing of several families; and as time
passed, we reached a serious impasse. Luckily for
us, there was Otto Huber, who could throw water
on the flames, and the work went on. It was hard
for Julian to type, due to the semireclined position
in which he had to remain, so he would turn his
manuscripts over to Cora, who was the only person
able to read and interpret his thick scratches. Thus
she also was a member of the flora team. Julian
was later awarded the prestigious "Order of Henry
Pittier" by the Ministry of the Environment for
the flora.
One peculiarity that I observed in Julian's char-
acter was that during his fieldwork, he never dared
to identify a plant to species, only to genus. For
example, once I asked him, “Julian, how do you
like that nice Palicourea fendleri?" Immediately
he criticized my confidence, which he termed as
an expression of ignorance and presumption, and
pointed out that P. fendleri was known only from
the coastal range of Venezuela, and now we were
in the Andes ....
Garden in Caracas, would he make a decision on
the identity of a plant by checking it against her-
barium specimens or sending it to one of his col-
Only later, at the Botanical
leagues. Once, I told him that I felt that he was
too insecure about identifying plants. He answered
sharply that he was a scientist and I was only a
rank amateur, that ignorance is petulant, and that
I should be more careful in my opinions.
In those years, Julian also devoted his weekends
to a survey of the plants of the wild areas around
his neighborhood of Santa Fe, which at that time
was being encroached upon by housing develop-
ments. That work was later included in a paper by
Paul Berry and Julian entitled “Florula of the
deciduous forests of Caracas.”
As a scientist, Julian was absolutely objective,
and he made no statement without proof to back
it up; but sometimes, I thought him to be too
objective. For example, when we were working on
the Flora of Avila, I was fascinated with a beautiful
orchid, Oncidium papilio, growing in Julian's gar-
den, which in the thirties had been collected

he wouldn't include any species in his treatment if
not supported by a more precise collecting locality.
But, if I were to make a collection of that orchid
from the mountain itself, he would include it in the
flora .... I did look for it indeed, but I couldn't
find a specimen; that is, until 1985 in the northern
side of the national park, seven years after the
flora was published.
In September 1979, Julian went back to Mis-
souri for a couple of weeks for the dedication of
the Steyermark Woods. Cora stayed in Venezuela
alone in their house, and an American lady who
lived close by kept in contact with her and took
her to the market whenever she needed to go. Cora
felt very uneasy and alone in Venezuela, and Julian
was making plans to bring or send her back to
Missouri. In fact, since some time earlier, he had
642
Annals of the
Missouri Botanical Garden
been in contact with Dr. Peter Raven, Director of
the Missouri Botanical Garden, and had told him
of his desire to write a Flora of the Venezuelan
Guayana. Dr. Raven was interested, and they be-
gan to consider ways to produce it. Although Julian
had become a Venezuelan citizen, he realized that
the only way to obtain the help that he needed was
to return to the large herbarium in Missouri, and
so he made final plans to leave Venezuela with Cora
in the spring of 1
All of his careful plans changed abruptly in
October of 1983. One night, when he arrived home
from the botanical garden, he found Cora tied to
a Chair, very scared. What had happened? That
afternoon, somebody rang the bell at the entrance
and when she opened the door, there were two
young men at the gate. One of them pointed a gun
at Cora and ordered her to open up. She did as
they said, and when they entered, they tied her to
a Chair with a blanket and searched the house.
They found very few things of interest and soon
left, leaving Cora tied to the chair, where she stayed
until Julian found her hours later. He called the
police immediately, and when the officers arrived,
and as a matter of routine, they asked Cora to
show them her passport. She went upstairs, still
very upset, and on her way back down lost her
footing and fell, breaking a bone in her right leg.
er leg was set in a cast, and she was released
from the hospital, but a couple of weeks later she
contracted pneumonia, and a week later, on No-
vember 4, 1983, she passed away at age 92. Her
last wish to return and see her country again was
unfulfilled.
I visited Julian frequently in the following weeks.
He spoke very little about what had happened,
perhaps trying to forget as quickly as possible. He
kept busy working and asked me seriously about
contributing the drawings for the flora of Guayana
that he had planned. In order to motivate me, he
placed at my disposition the thousands of color
slides he had taken during many years of explo-
ration. I started by choosing close-ups of flowers,
which would be the most useful for my work; but
as I went on, I was impressed by the many beautiful
slides of landscapes, and an idea came to my mind:
to write a book on the Guayana using many of
Julian's slides. So, without telling him anything, I
wrote an essay on the history of the search for E
Dorado, entitled “En la Tierra del Oro," and added
to it 100 of the slides. When I had the manuscript
completed, I showed it to Julian, who was at first
confused, because he didn't understand that I had
tricked him a little bit. Anyway, after he read the
manuscript and made some corrections, he agreed
that I should carry out the plan and went along
with me to an editor, who promised to publish it
as soon as possible, though it was not completed
until December of 1988, too late for Julian to see
-

In December 1983, I began the drawings for
the Flora of the Venezuelan Guayana using the
provisional survey of the herbarium in Caracas that
Julian made to find out which families were known
from the area. In April of 1984, he moved back
to his hometown of St. Louis, but only a few
months later he came back to Caracas for two or
three months to begin checking the herbarium sys-
tematically to record all of the plants collected in
the area covered by the intended flora. And in
February of 1985, Julian was in Caracas again.
This time, he had with him a young man, his
efficient assistant Bruce Holst, who helped in the
general inventory of the herbarium; he was admired
for his ability and correct Spanish.
Until then, except for the short trip in 1971 in
search of Julian's lost plants in San Carlos and
Cocui, I had never been on any expedition south
of the Orinoco River. Julian wanted to give me an
opportunity to see as much of the Guayana as
possible now, to help me in preparing the drawings
for the Flora by taking pictures, or making draw-
ings from live plants, as I preferred. So, in Easter
week of 1985, Julian, Bruce, and I headed for the
Gran Sabana, in Bolivar State, with the intention
of going as far as possible in the ten days that we
On that trip, we rented a car called a "Zephyr,"
a clumsy, two-wheel drive that, when weighed down
with all of our gear, barely cleared the ground.
Because of the busy vacation week, all of the four-
wheel drive vehicles were already rented. On the
rough roads of the south, everybody looked at us
in astonishment since it was the only two-wheel
drive in the whole Gran Sabana, but Bruce man-
aged to sort out the numerous ruts in the road and
cross the streams to make it all the way to Kamá
g the way, we collected mostly along
the road since Julian didn't want Bruce or me to
go too far into the woods and use up too much
time, but we managed to find numerous plants to
sketch and photograph that would be valuable for
my illustrations.
On our way back down to the lowlands, we had
a funny incident with a group of university students
camped by the side of the road who were in charge
of checking the cars returning to the north and
helping the tourists with information. As we slowed
Volume 76, Number 3
1989
Steyermark Recollections 643
down to pass them, the guard on watch blew his
whistle for us to stop, and when he saw some plants
that we had in the back of the car, he called for
the leader to come out of his tent. He asked for
our identification and told us that it was forbidden
to remove plants from the Canaima National Park.
Julian answered that he was Dr. Julian Steyer-
mark, working for the Ministry of the Environment
and...
“Are you Dr. Steyermark, the author of the
Flora of Avila?" he asked in delight. “I have
wanted to meet you for many years to congratulate
you on such a beautiful book!”
Immediately he called all of his helpers to come
out and insisted that all of us line up for a picture
to be taken with our arms around each other. When
the photographer apologized for a delay in taking
the picture, Bruce mentioned that there was no
hurry since he was standing next to the most beau-
tiful girl of the group.
In August of the same year, Julian and Bruce
were in Caracas once more. On this visit, Julian
received his retirement payment and immediately
purchased a Toyota Land-Cruiser for use on ex-
peditions by both the Caracas Garden and Missouri
Botanical Garden. We took it on its maiden voyage
to Puerto Ayacucho in the Federal Territory of
Amazonas (1-13 September 1985). We had some
trouble at the crossing of the Orinoco since a fierce
storm was coming up that made the pilot of the
ferry think twice about crossing the wide river. But
there was a long line of cars waiting, and at last,
some people convinced him to make the trip, hop-
ing to beat the storm. As soon as we were well out
into the river, it started to rain, and big waves
splashed over the floor of the ferry, obliging us to
take refuge under the covered area. Many pas-
sengers began regretting having started the trip,
and we were beginning to think that we might not
make it to the other side. Apparently Julian was
not at all concerned, even though his new car was
perched on the front of the ferry, since he sat
quietly under the overhang seemingly enjoying the
roller coaster. But after one hour or so of being
tossed around and getting soaked by the waves,
we reached the town of Caicara on the other side.
Bruce overheard one of the ferry attendants say
that our trip was the roughest that he ever made.
On that expedition, I was fascinated by the many
strange flowers that we found, especially with a
half-dozen species of Mandevilla, a vining genus
of the Apocynaceae family with showy yellow flow-
ers (a couple of new species would be described
later from those collections), and different species
of purple morning glories and mallows. Of course,
when I saw a pretty flower, I asked Bruce to stop
to take a picture; but Julian started getting bothered
with so many stops, and he ordered Bruce to follow
his instructions, not mine, and to go ahead without
stopping any more to make better time. Julian
looked very bothered when he said that, and we
went on a short time without speaking, all of us
feeling tense. I knew Julian as a mild-mannered
man, who only on a few occasions would lose his
patience, and usually for just a short time. So, I
began to tell him in a humble voice: “Julian, sup-
pose we see a donkey on a bicycle. Shouldn't that
be a reason to stop and take a picture? ...” (No
answer). Again, a bit later: “Julian, and if we saw
a mammoth flying over that boulder over there,
wouldn't it be a good reason to stop and take a
picture? . . .” No answer! I understood that maybe
went too far with my stupidities, and | decided
o shut up and resign myself to his wishes ....
Suddenly Julian cried:
“Bruce, stop! . . . Bruno, did you see those big
yellow flowers in that bush over there? ... Have
you already taken a picture of them?"
n the way back to Caicara a few days later,
Bruce was driving slowly on the muddy road to
avoid the many potholes, but Julian asked him to
speed up, thinking that when we arrived in Caicara
at the hotel, he had to record in his field book all
the plants he collected that day. Bruce tried to
obey, but when he came across any rut, he would
slow down again. At last Julian lost his patience
and ordered him to turn over the wheel; and the
Land-Cruiser started away at full speed, jumping,
splashing, and shaking us up. We arrived at Cai-
cara early that evening, and we were the first
customers in the restaurant, as was usual with
Julian.
The following day, early in the morning, we
crossed the Orinoco River again, this time with a
nice sun and good weather, and by evening we
were in Caracas.
As a man who loved nature, not only to enjoy
it but also to make it known and be loved, he
supported with his own money several expensive
expeditions to Guayana. He also paid for some
botanists from Venezuela to visit herbaria in the
United States and for some U.S. botanists to go to
Venezuela to work on treatments for his flora. As
he was demanding with himself, he used the same
standard for others. I was in the office one night
when Luis Marcano Berti, a Venezuelan botanist
whose trip to the New York Botanical Garden was
funded by Julian, called. “Are you also working at

night and on the weekends?" Julian asked. “Yes!”
"Oh, very good,” answered Julian contentedly.
In my case, although he wanted me to work
hard on the drawings, he wished too that I would
be able to see and enjoy from time to time the
natural beauty of Missouri and especially of the
Ozarks. To help me out, he asked Bruce to take
me camping some weekend, which we did several
times. So, with their help, I was able to get to know
some of that wonderful country of Missouri, and
also gaze at the stars through Bruce's telescope.
Bruce, for his part, would tell me that in late
October, when Julian was better, we would all go
out again together to see the fall colors, which
delighted Julian so much.
The weekend after Julian passed away, Bruce
took me out to the Ozarks. The sun was bright
that afternoon, and the many colors of the falling
leaves were spectacular. We regretted that Julian
was not with us to enjoy one of his favorite shows
of nature.
That night, Bruce and I sat a long time looking
at the fire. The words came out with difficulty, and
several times I had to bite my lips not to weep.
Both had lost a great friend, and I missed a man
who for me was like a father. At that moment we
felt closer than ever before, feeling the responsi-
ility we now had to bear of completing Julian's
great dream, but glad to have been with Julian in
his last hours.
A few days later, while writing down these mem-
ories, a letter came from Victoriano Carreno, dated
Caracas, October 4, 1988. It said: "Dear friend,
I heard that you were sick, and I am praying to
God for your quick recovery. All of us remembe
you, and we hope that you can visit us again... .””
Surely, Julian would have enjoyed receiving this
letter with the sincere wishes of Victor, the faithful
field assistant who during many years helped him
get a bit closer to his dearest dream.— Bruno

The return of Dr. Julian A. Steyermark to Mis-
souri during the last week in September [ca. 1978]
provided me with a chance to talk again to my
esteemed friend and to reminisce about my first
experiences with him over two decades ago.
I had grown up on Steyermark's Spring Flora
of Missouri, which I found very useful in adjacent
southern Illinois. While I
the Missouri Botanical Garden 1 —56, working
on my Ph.D. at Washington University, I was
constantly reminded of Dr. Steyermark because of
his vast collections in the MBG herbarium, because
was doing research at
9
of his prodigious writings, and because of the stories
retold about him by Edgar Anderson, Bob Wood-
son, and others.
Following my Ph.D., I began my professional
career in the Department of Botany at Southern
Illinois University in January 1957. It was my
great fortune that during the three-month spring
quarter in 1958, Julian Steyermark was offered a
Visiting Professorship in the Department of Botany
at SIU. The impact that those three months had
on my professional career cannot be overstated.
Our department at that time was in cramped
quarters. | already was sharing a 16 by 8-foot
office with Professor John Voigt, the departmental
ecologist. Since Dr. Voigt's interests and mine were
more closely aligned to Dr. Steyermark's interests,
the three of us were crowded into this small office.
Steyermark and I spent every day and partway
into nearly every evening working side by side. He
was putting the finishing touches on his Flora of
Missouri and I, along with my wife, Beverly, was
revising Jones's Flora of lllinois. Often Steyer-
mark would quiz me on some specimen he was
working on or sketching. Many species previously
unknown by me were quickly and eagerly learned.
While much of the three months was devoted
to serious botany, Dr. Steyermark would take a
little time off now and then to come to our home
for dinner. On one occasion he took my wife and
me to the local movie theater to see War and
Peace. I recall the incident vividly because Julian
insisted on picking us up in his vehicle, an Inter-
national Scout built high to enable him to negotiate
Missouri's back roads. The Scout was so high that
I had to climb awkwardly. My poor wife stood
helplessly at the door until Dr. Steyermark boosted
her up into her seat!
One of my most pleasant recollections was an
overnight visit to Steyermark's estate near Bar-
rington, Illinois, north of Chicago. Julian had talked
so often about the wildflower preserve he had built
that my wife and | were thrilled to be invited to
see it. We arrived early one afternoon. Julian guid-
ed us over about half of the property, pointing out
with great enthusiasm the many species transplant-
ed from the Ozarks. That evening we talked of
plants, browsed through his extensive library, and
listened to classical music.
We awoke the next morning to the delightful
smell of bacon frying. Cora, Julian’s wife, hac
prepared a feast, including the most delicious baked
eggs my wife and I had ever eaten. The rest of
the morning was spent walking over the remainder
of the grounds before we all began the long drive
back to Carbondale.
From mid-March to late April 1958, Steyer-
Volume 76, Number 3

Steyermark Recollections
mark enthralled me with stories of his experiences.
I was particularly excited about his rediscovery in
1957 of the very rare and little-known Geocarpon
minimum. This species had been found originally
in Jasper County [Missouri] in 1913. This re-
mained the only known station until Steyermark
had rediscovered it in St. Clair County [Missouri]
in 1957. My nagging at Dr. Steyermark to show
me Geocarpon paid off. He agreed to take Dr.
Voigt and me with him on a three-day excursion
to see if we could discover additional stations for
this dwarf rarity. *
We left Carbondale on May 2, heading in the
general direction of Springfield, Missouri. Leaving
Cape Girardeau, we stopped briefly at the Bollinger
Mill and then headed into the Ozarks. Up and down
lettered and double-lettered county highways, past
shortleaf pine woods, over clear, rock-bottome
streams we went, Steyermark pointing out species
right and left. We made frequent stops, usually
“Wait!
There's a county record." I tried to absorb all the
after an enthusiastic comment such as
species as fast as I could, but Steyermark never
relented. We screeched to a halt in Bollinger Coun-
ty, pulling off the road next to a steep, wooded
cherty slope. Julian asked if any of us had ever
seen the little sedge Scirpus verecundus. We re-
plied in the negative, and off we went down the
slope. Scirpus verecundus was not known from
Bollinger County, but Julian was optimistic, saying
that this slope looked just right for the little plant.
In what could not have been more than five min-
utes, the woods echoed Steyermark's voice: “Whee!
Over here. I’ve found it!” Scrambling over the
treacherous chert, Dr. Voigt and I made it to the
kneeling botanist who crouched over a four-inch-
tall tuff of green. I had seen my first Scirpus
verecundus, and I was never to forget the habitat.
Some 15 years later, while exploring in Alexander
County, Illinois, I camp upon a similar steep, cherty
slope. Recalling my earlier experience, I began to
comb the woods and was rewarded by making the
first discovery of Scirpus verecundus in Illinois.
By late afternoon we had reached Dallas County
and were heading along Route 43 when Steyermark
observed that the little chickweed on the road shoul-
der looked peculiar. On closer look, the plant in-
deed was different from anything we had ever seen.
We learned later that the plant was Cerastium
pumilum, a new record for Missouri.
We persisted beyond supper and into the dusk-
iness of twilight. By dark, we were still on the road.
I began to understand how Steyermark had been
able to canvass every square foot of Missouri in
30 years—he never stopped to rest. I saw my first

Ozark tarantula, scurrying aross the road in the
glow of our headlights. Finally we stopped for camp
at about 9:30, reeling from the vast amount of
information imparted by Dr. Steyermark.
e arose early on May 3 in anticipation of
seeing Geocarpon. We had entered Polk County
[Missouri] near Graydon Springs when Dr. Stey-
ermark announced that we had arrived at a likely
looking spot for Geocarpon. It was a glade on a
west-facing sandstone escarpment next to Coates
Branch, a tributary of the Little Sac River. We
quickly found /soetes butleri, Talinum parviflo-
rum, and Arenaria patula, species known to be
associated with Geocarpon at its other stations.
Then, in a small, moist depression on the glade,
we spotted it—dwarf, two inches tall, semi-suc-
culent. At this stage, the plants were wine-purple.
Once we knew what we were looking for, we began
to spot another, and another and yet another. Our
discovery marked the third known location for Geo-
carpon in the world! On the same glade, I also
saw for the first time in my life Selenia aurea,
Saxifraga texana, and Collinsia violacea.
Our spirits were buoyed by these discoveries.
We hastened into Green County and stopped at a
likely looking sandstone glade near Pearl. We no-
ticed Selenia aurea and Saxifraga texana from
a distance and, more closely, /soetes butleri. It
certainly would be just a matter of time. Sure
enough, the wine-purple plants of Geocarpon min-
imum became evident after we had wandered into
an adjacent glade. I don't recall how many spec-
imens there were but I would think there were
dozens of them
s we were hopping over the glade in our
crouched positions, we happened upon a small plant
previously unknown from Missouri. It was Scler-
anthus annuus, the awlwort of the Caryophylla-
ceae.

With our success in finding Geocarpon, we
headed into Dade and Cedar counties, stopping at
several glades. Much to consternation, we
couldn't find Geocarpon at any of them. By late
afternoon,

had planned to camp at beautiful Alley Springs.

' he shouted once, as we whizzed by
a clump of two-foot tall grasses. Most people have
trouble identifying this species in the daylight with
the specimen in front of them, but Steyermark's
identification was right on the money.
We got to Alley Springs at last. The long, eventful
day was conducive to good sleeping, and I scarcely
noted that I was spending the first night of my life
atop a hard, slatted picnic table!
Next morning we were soon on the road, finding
more goodies. About two miles west of Piedmont
along Highway 34, we found Cerastium brach y-
petalum, the third collection of it in Missouri. Near
Cape Girardeau, we discovered our second station
for Cerastium pumilum. Since the afternoon was
young, Dr. Steyermark expressed a desire to go
into Perry County to a deep ravine he had had his
eyes on for years. The ravine was new collecting
ground for Julian, and he took his plant press with
him. He is the only botanist I have ever been in
the field with in the United States who carries his
press with him. Most of us use plastic bags or tin
cans (vascula), and our semiwilted specimens are
proof of it. Steyermark had custom-made his own
press with a hinged back that opens like a giant
book. Our visit to the ravine netted nearly a dozen
records for Perry County.
We got back to Carbondale early in the evening,
finishing a three-day red-letter trip I will never
orget.— Robert Mohlenbrock, Dept. of Botany,
Southern lllinois University; Ain with per-
mission from Missouriensis 1(3):
My first meeting with Julian Steyermark was at
the Caracas Botanical Garden in 1960, after re-
turning from landscape architecture studies at the
hode Island School of Design. At that time, there
were very few books in Spanish about local orna-
mental plants. As a landscape architect, | felt it
would be interesting to write a book about tropical
trees that would be useful for landscape projects.
Gradually, my visits to the Botanical Garden be-
came more frequent. Julian was always ready to
answer my many questions about trees and other
plants, as well as to identify living material that |
brought in.
In 1963, we made a three-day expedition to the
mountains above the coastal town of Naiguatá in
a very rich rainforest at 1,000 m elevation and
only about 60 km by road from Caracas. We found
many new species there including huge trees, and
we collected the bromeliad Guzmania sanguinea
for the first time in Venezuela. At later dates we
went on other trips, and even met at the top of
different tepuis with a group from the Terramar
Foundation.
n 1962, when I began to write and illustrate
a color edition of ornamental trees in Spanish,
Julian kindly supervised my work. We also main-
tained close contact over the next eight years as
I worked on my second book called Garden Plants
of the Tropics (printed in English and Spanish).
Julian wrote the introduction for me.
Despite his intensive work in families such as
the Rubiaceae, Julian was always intrigued with
the beauty and wonderful colors of the Bromeli-
aceae. The enchanting forms and the extravagance
of the flowers fascinated him, something we cer-
tainly shared. I began to fancy the idea of making
a book on Bromeliaceae along with him. The first
step was to compile photographs, including ones

Steyermark Recollections 647
Julian occasionally took of the Bromeliaceae on
the tepuis. Because of the difficulties of getting to
the Guayana, his pictures were particularly valu-
able. Soon he agreed to write the text for the book
on Bromeliaceae of Venezuela with me. It took
about five or six years to organize the text and
pictures. From 1980 to 1983, Julian was already
very involved with the Flora of the Venezuelan
Guayana project, so I decided to do most of the
text in order to facilitate his work. I would generally
give him eight to ten pages of text to check and
translate; he would review these and return them
to me after a few days. He was very adept at
translating text from Spanish to English and vice
versa. Once, Julian became upset with me because,
according to him, I was including too many species,
and he had no more time to keep reading, cor-
recting, and translating. Although there were about
230 species prepared, I went on against his wishes
to include a few more that I had collected at the
last minute. I insisted that he go over these too.
He always wanted to please people, so he did the
final effort to finish the last translation and cor-
rections for our work. I can still remember hearing
him along the corridors of the Botanical Institute
saying, “I am very busy with the Flora of the
Guayana and have no time to do anything else.
Please can you stop adding new data to the book?
Our manuscript was handed to the printer just dio
before Julian left Caracas to move to St. Louis, but
then the book took about two years to be printed.
Before leaving his post at the Caracas Botanical
Garden, Julian was awarded diplomas and medals
together with a reception and a farewell party, by
the National Parks Institute in recognition for his
tremendous work accomplished in Venezuela. He
was most happy and pleased by these honors. After
Julian's departure from Venezuela, we kept in touch
by mail about the last details and corrections of
the proofs of our book. He returned many times
to Caracas with his assistant Bruce Holst to work
and collect for his monumental Flora of the Ven-
ezuelan Guayana. Although he was expecting to
finish this project, destiny had other plans.— Fran-

Mas las almas de los justos están en la mano de
acia, y como un aniquilamiento su partida
de entre nosotros: mas ellos, a la verdad, reposan en
paz.
Julián Steyermark no está hoy entre nosotros, pero
no podemos decir que está muerto, no podemos
decir que ha desaparecido; no existe la muerte para
un hombre que hizo tantos caminos. Su obra como
su bondad son imperecederas.
Su alma se separa de su cuerpo ya inmóvil el
sabado 15 de octubre, allá lejos, en tierras norteñas,
en la ciudad de Saint Louis. Allá mismo donde nació.
Pero la mayor parte de su vida, los mejores años,
los pasa con nosotros.
o ha habido hombre que haya estudiado más
nuestra flora. La pasión máxima de Julián Stey-
ermark fue la Guayana, con sus imponentes te-
puyes, pero también recorrió con sus ojos bien
abiertos a toda Venezuela, viendo y colectando
muestras botánicas.
Deja una valiosa obra. Era infatigable. Fueron
múltiples sus contribuciones: las Rubiáceas, las Pi-
peráceas, exploraciones botánicas de las regiones
orientales, nuestra vegetación, la Sierra [mataca y
altiplanicie Nuria, la flora de la Sierra de San Luis
en Falcón, el Cerro Autana, Cima del Macizo Jaua,
Cerro Patao en Paria, el Roraima, el Auyantepuy,
la flora del Avila.
Julián Steyermark fue un excelente botánico.
Un incansable admirador de nuestra naturaleza.
Coleccionó miles de muestras para herbario. Clasi-
ficó una cantidad igual. Atendió centenares de con-
sultas. Pero lo más importante es que fue un hombre
bueno. Honesto, noble, muy sencillo, extremada-
mente sencillo, cordial, amable, siempre dispuesto
a responder cualquier pregunta. El gran comple-
mento de su erudición era la sencillez.
No podemos decir que Julian Steyermark ha
muerto. Tal como está escrito en la Biblia: las almas
de los justos están en la mano de Dios, y no llegará
a ellos el tormento de la muerte eterna. Ellos a la
verdad, reposan en Mauricio Ramia, Uni-
versidad Central de Venezuela; palabras pro-
nunciadas en el acto de apertura del IX Congreso
Venezolano de Botánica, el día 13 de noviembre
de 1988 en Caracas.
Julian took my wife and me for our first look
at the Grand Savanna in the Guayana Highland,
and with us the Dunstervilles looking for orchids
and to whom the place was an old story. As we
entered the Grand Savanna, Julian and I stopped
on an area of dry open sand and discovered a tiny
sundew with one or two sessile flowers in the center
of the rosette. Julian named it Drosera felix be-
cause of the happy event of our visit.
Later on our trip we were camping one night
by a small stream, and while Julian was preparing
supper, I went out exploring and found an aquatic
aroid in a deep pool that the stream had hollowed
out of the solid rock. Julian came when he was

free and with his longer arm was able to collect it.
It proved to be a new genus, and George Bunting
named it Jasarum, compounding it with Julian's
initials and Arum because Julian had discovered
so many new genera that such tactics were nec-
essary. Later I contributed with the bromeliad Ste y-
erbromelia.— Lyman B. Smith, Smithsonian In-
stitution.
I participated in a number of field trips to Mis-
Jr. Steyermark was accumulating
vouchers for his flora. The average trip down [from
Chicago] was about six hours, and he would con-
tinuously quiz me on botanical questions.
Typical questions would be: “What type of pla-
centation occurs in the Caryophyllaceae?" or “What
monotypic genus in the Cruciferae is endemic to
the Kerguelen Archipelago?" or “Name all of the
phanerogamic genera native to Antarctica." In
many cases he was actually thinking about the
second question while | was working on the answer
to the first one. So you get some idea how many
questions were involved on a given trip.
would say that he, perhaps more than any
other person, stimulated my interest in taxonomic
botany.— Floyd Swink, Morton Arboretum.
Julian knew Missouri as did few others, and he
had a remarkable memory of people, sites, and
plants. The Department of Conservation bought
the land where Julian found pondberry [ Lindera
melissifolia] from a man called O. K. Hamlett.
e were discussing this site one day and Julian
not only remembered O.K.'s name but he described
in detail where several of the rare species were
located on the property. I had been on the property
a week earlier and Julian talked as if he had — not
25 years before.
When the Natural History Section first started
to locate and buy significant sites (often with rare
or endangered species) we used a list Julian had
prepared 20 years before. The same list went into
the Natural Heritage Database prepared by The
Nature Conservancy and the Department of Con-
servation.
Thanks to Julian, a number of these areas are
now State Natural Areas and protected for those
who will come after us. Sand Ponds (the pondberry
site), Pickle Springs, and Barn Hollow are exam-
ples.
Every time we walk in these places Julian's shade
will be there too.— John Wylie, Retired Natural
History Officer, Jeflerson City, Missouri.
Members and friends of the Garden were sad-
dened by the death of Dr. Julian Steyermark on
Saturday, October 15, 1988. Steyermark was one
of the Garden's best-known research botanists,
famous locally and around the world for his bo-
tanical collections and publications, and for his
strong support for conservation of the environment.
Born in St. Louis on January 27, 1909, Julian
Alfred Steyermark enrolled in 1925 in the Henry
Shaw School of B
between the Garden and Washington University,
where he received A.B. (1929), M.S. (1930), and
Ph.D. (1933) degrees. He also earned an
degree (1931) from Harvard University. During
his early years at the Garden, Julian indulged his
other great love, painting watercolors of native flora
and plants in the Garden's orchid collection. At
that time he began collecting herbarium specimens
in Missouri and other states, and by graduation in
1933 he had already surpassed the quantity most
botanists collect in a lifetime.
After college, Steyermark assisted Robert
Woodson, a research botanist at the Garden. This
led to his first tropical expedition, a collecting trip
to Panama in 1934. He then taught high school
in the St. Louis area for two years before moving
to the Field Museum of Natural History in Chicago
as an Assistant Curator. For the next 21 years
Steyermark worked on the Flora of Guatemala
and other tropical projects during the week, but
continued his Missouri studies in his spare time. A
revealing and delightful look at those weekend ex-
peditions from Chicago to the wilds of Missouri was
provided by his wife, Cora, in her book, Behind
the Scenes, published by the Garden in 1984 (and
still available in the Garden Gate Shop).
efforts culminated in the massive Flora of Missouri
3). This widely acclaimed manual is often re-
ferred to as the state's “botanical bible" and has
sold out six printings.
During World War II, Steyermark was sent to
South America as part of the government's pro-
otany, a cooperative program
These
gram to locate new botanical sources for quinine.
At that time he first visited the Venezuelan
yana region, which he lovingly referred to as *“The
Lost World.” (See the Missouri Botanical Garden's
Bulletin, November /December 1986 and July,
August 1987.) His interest in this picturesque area
was so great that in 1958 he left the Field Museum
to take a position at Instituto Botánico in Caracas,
, Julian returned to the Mis-
Gua-
Venezuela. In

plete his last major project, a flora of the more
than 9,000 plant species in the Venezuelan Guay-

ana. This task remains for his friends and col-
leagues to complete.
Bruce Holst, project coordinator for the Flora
of the Venezuelan Guayana, said, “It was a real
thrill and a tremendous learning experience to work
in the field with Julian. He really had an “eagle
eye' for spotting plants, and if you didn't see some-

ieldwork was very special for Julian. He never
took any ‘vacation,’ he went on field trips instead.
He was just so excited about collecting plants, it
was impossible not to be caught up by his enthu-
siasm. He always likened collecting to a ‘treasure
hunt’! Even with his two artificial hips, he would

fall down, laugh about it and push on....”
Steyermark received numerous honors during
his eventful life, including awards and citations
from the governments of Guatamala and Vene-
zuela, and the
1979
Sierra Club awarded him a special citation for his
ardens Henry Shaw Medal
That same year, the Ozark Chapter of the
conservation efforts, and the Missouri Department
of Conservation named the 73-acre Julian A. Stey-
ermark Woods, near Hannibal, in his honor.
To commemorate Steyermark's achievements,
the Garden has established a fund to promote bo-
tanical research and expeditions in Latin America,
particularly in the Venezuelan Guayana region, and
to support research on the natural history of Mis-
souri. In addition, the Missouri Department of Con-
servation and the Garden are revising Julian's best-
known book, which will be retitled Steyermark's
Flora of Missouri, a lasting memorial to a giant
among botanists.

A memorial service was held for Julian Stey-
ermark at the Garden on October 25, 1988. In
the eulogy, Dr. Raven said, . His last work will
be completed here, and will stand as a final tes-
tament to his industry and to his scholarship. As
for any human being, however, what will prove to
be even more important to all of us will be our
memories, for Julian Steyermark was an inspira-
tional person, one who projected his own values
without trumpeting them, and thereby enriched all
our lives, as he did the literature of botany.”
George Yatskievych heads the Garden's joint
project with the Missouri Department of Con-
servation to revise Steyermark's Flora of Mis-
souri.— Luther Raechal assisted Dr. Steyermark

ABSTRACT
In his 62 years of actively collecting plants (1925-1987), Julian Steyermark described 2,392 taxa, including 1
family, 38 genera, an species. He named plants

Julian Steyermark collected his first plant in
1925, his last in 1987, both in Missouri. He col-
lected so many plants, over 130,000 collections,
that he received recognition from the unusual source
of the Guinness Book of World Records. Julian
was most known for his Flora of Missouri, and his
work in Guatemala and Venezuela, yet he described
plants from 26 countries and from 16 states in the
His statistical record is astonishing. Julian Stey-
ermark described a single family, 38 genera, and
1,864 species. Including other ranks, he named at
least 2,392 taxa. Taxonomic Literature (second
edition) cites an as yet unobtainable reference
edited by H. Villanueva, 1977 (Bibl. Alfredo Jahn,
Bol. Inf. 9: 9-12) which purports to contain the
‘most important of over 350 publications’ by Julian
Steyermark. It is estimated by the present author
that this compilation lacks about 80 references,
although the exact number is unknown.
In the list of types families are arranged alpha-
betically, and species alphabetically within families,
then by descending rank within species. Data in-
clude the name, author(s), place of publication,
collector, collection number, date of collection, lo-
cality, elevation, and depository. Current nomen-
clature (which are not referenced in the bibliog-

SYSTEMATICS OF ZAPOTECA Héctor M. Hernández?
(LEGUMINOSAE)!
ABSTRACT
Zapoteca (Leguminosae: Mimosoideae) is a si ies well- Veces genus belonging to the tribe Ingeae
distributed from the southwestern United States and northern Mexico to Piin Argentina and the West Indies.
The highest concentration of taxa occurs in the dry ben of so aod n Mexico and, to a lesser extent, in Central
America and the northern Andes. The predominance of allopatric distributions and the apparent low frequency of
hybrids suggest that r in this genus has primarily arisen from genetic differentiation of a isolated
populations. The recent climatic episodes of the dulce appear to m had a prominent role on the current
distributional patterns of Zapotec a species. Zapoteca species have similar reproductive biologies. All probably have
nocturnal anthesis and are pollinated by ad settling moths. Self-compatibility appears to be widespread in
the genus, Z. tetragona being the only known self-incompatible species. Andromonoecy is another widespread
component of the breeding system of Zapoteca species. This probably maximizes the use of reproductive energy
without reducing pollinator attraction. The basic chromosome d of Zapoteca (x = 13) and some of the generalized
characters of the polyads (i.e., acalymmate, discoid, 16-grained polyads) indicate a relationship between Zapoteca
and the remaining genera of the Ingeae, with the exception of Calliandra sensu stricto, which is cytologically and
morphologically isolated in this tribe. I recognize 17 species in Zapoteca, three of which (Z. alinae, Z. andina, and
ana) are newly described. Eleven subspecies are recognized, of which Z. portoricensis subsp. pubicarpa is
newly described. A subgeneric classification is proposed, where taxa are grouped into four morphologically distinct
subgenera: Nervosa, Zapoteca, Aculeata, and Amazonica. The subgenera are based primarily on differences in
vegetative characters: number of pairs of pinnae, number of leaflet pairs per pinna, leaflet size, leaflet texture, venation
patterns, and stipule type.
RESUMEN
Zapoteca (Leguminosae: Mimosoideae) es un género relativamente bien delimitado que pertenece a la tribu Ingeae.
Se distribuye desde el suroeste de los Estados Unidos y el norte de México hasta el norte de Argentina y las Antillas.
La más alta concentración de taxa se da en los bosques tropicales secos del sur de México y, en menor medida, en
Centro América y en la porción norte de los Andes. La predominancia de distribuciones alopátricas, en combinación

scandent. Zapoteca portoricensis subsp. flavida
and Z. amazonica grow in moist thickets supported
by neighboring shrubs. Similarly, Z. caracasana
branches near the base of the primary stems and
has spreading branches that become prostrate or
subprostrate. The scandent and prostrate habits
are found exclusively in warm, moist habitats.
Leaves. The leaves of all species of Zapoteca
are stipulate and twice pinnate with opposite leaf-
lets. The wide variation in leaf characteristics pro-
vides an excellent basis for classifying members of
the genus. Mature leaflets vary in length from about
0.5 em in Z. alinae and Z. media to a maximum
of 22 cm in Z. amazonica. In addition, there is a
clear tendency towards a reduction in number of
leaflets concomitant with an increase in leaflet size.
In all species of subg. Zapoteca the pinnae have
from several to many pairs of leaflets; by contrast,
in Z. amazonica the leaves have only one pair of
pinnae with a single pair of large leaflets. Fur-
thermore, all members of subg. Zapoteca have
relatively membranous leaflets, whereas in the re-
maining species they are clearly chartaceous to
coriaceous.
Extrafloral nectaries are uniformly present in Z
filipes, Z. scutellifera, and Z. nervosa. They are
located between the insertion of the pinnae and,
less frequently, between the distal pairs of leaflets.
In Z. scutellifera and Z. filipes an additional nec-
tary is located near the base of the petioles. The
nectaries are more or less cup-shaped in Z. scu-
tellifera and Z. nervosa and cylindrical in Z. fi-
lipes. According to Zimmerman's classification
1983), all of these fall into the "Hochnek-

vein at an acute to right angle, curving abruptly
to join superadjacent secondaries to form a loop.
In addition, loops are always enclosed by arches
formed by higher-order veins. Zapoteca nervosa
differs from the remaining examined species in
having eucamptodromous venation in the basal half
of each leaflet and brochidodromous venation in
the upper half (Fig. 30). Furthermore, the tertiary
domains in the leaflets of this species are elongate
and parallel to the primary vein, and the free-
ending veinlets are more abundant in the distal
area and usually are once- or twice-branched.
The marginal venation is looped in all Zapoteca
species with the exception of subg. Amazonica,
where it is clearly fimbriated. Similarly, all species
of the genus have incompletely closed areoles, ex-
cept Z. amazonica and Z. microcephala, which
have imperfectly developed areoles.

reflecting taxonomic affinities between the two sub-
genera. These two species share the basic brochi-
dodromous venation pattern of the genus; however,
they differ in their marginal venation and in the
orientation of their high-order veins and veinlets.
Although the marginal venation of these two species
is clearly looped, occasional free-ending marginal
veins are present. The veinlets are characteristi-
cally oriented towards the admedial-basal area of
the leaflets in these two species.
Zapoteca amazonica and Z. microcephala have
several characters in their leaves that depart from
the rest of the genus. The tendency towards the
development of larger leaflets concomitant with a
reduction in their number in these species is prob-
ably associated with an increase in the degree of
organization of leaflet venation. Hickey (1977) pro-

posed a system of leaf classification based on in-
creasing levels of regularity of venation (leaf ranks)
which provides a useful scale here. The venation
patterns of the two species of subg. dmazonica
reflect an advanced condition because their tertiary
veins have relatively regular courses (third rank;
see Fig. 48). In contrast, the leaflets of the re-
maining species of Zapoteca fall in the second rank
because their tertiary and higher-order veins are
random in course and are usually not well differ-
entiated from the lower orders. Of particular in-
terest is the presence of two co-primary veins (Fig.
48) in the leaflets of Z. amazonica and Z. micro-
cephala. This probably indicates leaflet. fusion.
Hickey & Wolfe (1975) reported that leaflet fusion

Stipules. The stipules are persistent, leafy,
and possess a series of veins running parallel to
the margins (Figs. 5, 6); in most species the stipules
are conspicuous (e.g.. Z. amazonica, Z. tetra-
gona), although in some they are very small (e.g.,
Z. tehuana). Exceptional in this respect is Z. acu-
leata, which has spinescent stipules (Fig. 46), and

INFLORESCENCES AND FLOWERS
Inflorescences. The flowers are consistently
arranged in compact, homomorphic, spherical,
capitate inflorescences. In the basic plan of inflo-
rescence organization, solitary or fasciculate pe-
duncles are axillary and subtended by a leaf, as in
Z. alinae, Z. media, and Z. aculeata (Fig. 7A).

however, an evolutionary trend toward
which reaches its extreme in the two species of
subg. Amazonica, where the leaves are always
vestigial, and the inflorescence therefore appears
to be an elongate panicle (Fig. 7D, E). Transitional
forms between the two extremes are found in
several species of subg. Zapoteca (Fig. 7B). For
instance, in Z. mollis, Z. portoricensis, and ad-
ditional species, the subtending leaves start deve-
loping during or after anthesis. Sometimes, how-
ever, the subtending leaves never develop, as in
some individuals of Z. caracasana (Fig. 7C) and
Z. formosa, in which the capitula are apparently
aggregated in paniclelike inflorescences

POLLEN
The diversity of pollen types in subfamily Mi-
mosoideae has been studied extensively by several
authors (Guinet, 1969, 1981— a review; Sorsa,
1969; Niezgoda et al., 1983). One of the outstand-
ing features in this subfamily is the high frequency
of permanently compound grains, these either in
tetrads or more commonly in polyads. As Guinet
(1981) and others pointed out, the basic polyad
type in the Mimosoideae is the acalymmate type,
in which the individual grains are more or less free
from one another. This form of polyad cohesion is
in contrast to the calymmate type, where the ex-
ternal layer of the exine is common to all cells.
Calymmate polyads are found in Calliandra.

polyads (Figs. 8-13). The eight central grains,
which are distributed in two rows, are morpholog-
ically different from the peripheral grains (i.e., the
pollen grains exhibit heteromorphy). The external
layer of the exine has an undifferentiated granular
structure, and the individual grains is al

are less pronounced on one side. Such areas some-
times occur on some or all of the peripheral grains
of Z. alinae polyads (Fig. 9

variation in the texture (density) of the valves,
which is of taxonomic value. In this respect, the
species may be arranged into three groups: 1) Le
lambertiana and Z. filipes with thin, membranous
valves; 2) the remaining species of subg. Zapoteca,
along with Z. nervosa, with thick, membranous
valves; and 3) Z. aculeata, Z. microcephala, and
Z. amazonica, with coriaceous valves. [t is im-

ricensis subsp. pubicarpa, and Z. formosa subsp.
salvadorensis, which are short-pubescent, densely
villous, puberulent, and pilose to densely pilose
respectively.
Seeds. In all species of subg. Zapoteca, the
seeds are widely ovoid to rhomboid and compressed
and lack rupture lines, arils, or wings (Figs. 16,
17). In most members of this subgenus the testa
is mottled, or dichrome, in which case the area
encompassed by the pleurogram (areola) has a
lighter color than the outside area. There is con-
siderable interpopulational variability in seed size
and the coloration of the testa, especially in Z.
formosa; by contrast, Z. tetragona appears to be
consistent in having dark, monochrome, ovate seeds.
Another seed feature is the pleurogram, common

This dispersal mechanism, however, does not
explain the presence of species such as Z. formosa,
Z. caracasana, and Z. portoricensis on islands,
which they presumably reached by long-distance
dispersal over water. Zapoteca formosa, for in-
stance, occurs throughout the West Indies and on
some islands off the Mexican Pacifice coast (Revilla-
gigedo Islands). Populations of this variable species
frequently grow in coastal areas. Although exper-
iments have shown that seeds and mature pods of
Z. formosa subsp. formosa taken from a coastal
population of the Yucatán Peninsula floated for
only two to four days in seawater, the seeds are
highly resistant to saline water. As shown in Figure
18, seeds from this population (Hernández 940)
germinated after soaking in saline. water (3.4%
sodium chloride) for up to 70 days. Most of the
seeds germinated normally when they were me-
chanically scarified and transferred to petri dishes
in a medium moistened with fresh water. Ridley

for a long time (De Candolle, 1825; Compton,

classifications in Leguminosae

without lens-shaped structures. In this connection,
it is reasonable to hypothesize that Z. nervosa
represents an Efe line that separated from
the main stock early in the evolution of the genus,
and its peculiar morphological features would be
explained by divergent evolution. The lack of are-
olate, lens-shaped thickenings in the polyads of Z.
nervosa, a character also absent in the remaining
genera of the Ingeae, appear to represent a prim-
itive condition within Zapoteca and suggests that

the species of the remaining subgenera are char-

a phylogenetic link between the two subgenera.
Subgenus Aculeata contains only Zapoteca
aculeata, which is characterized primarily by spi-
nescent stipules (a characteristic that has clearly
been derived within the genus), by an apparent
arborescent habit, and by pinnae having fewer pairs
of chartaceous-coriaceous leaflets than those of
subg. Zapoteca. The coriaceous pods of Z. acu-
leata resemble those of subg. Amazonica.
Subgenus Amazonica is made up of Z. ama-
zonica and Z. microcephala, which are charac-
terized by having the most obvious combination of
apomorphic features in Zapoteca. Their leaves are
reduced to two or three large, coriaceous leaflets
in each pinna. This is the result of an evolutionary
trend toward reduction in the number of leaflets
associated with increased leaflet size. This trend is
also seen in other genera of Mimosoideae (e.g.,

these species have a number of common architec-
tural features reflecting an increased level of or-
ganization, which is also interpreted as an advanced
condition. A progressive trend toward suppression
of leaves subtending the inflorescence in Zapoteca
has resulted in the highly specialized, elongate
pseudopanicles of these species. Among other clearly
apomorphic features of subg. Amazonica are the
elongate seeds of Z. amazonica, which lack the
characteristic pleurogram and are the largest in
the genus.
BIOGEOGRAPHY
Zapoteca ranges from the southwestern United
States (southern Arizona and southwestern Texas)
and northern Mexico, from about latitude 32°30'N,
southward through most of Mexico, Central Amer-
ica, and much of South America (Venezuela, Co-
lombia, Ecuador, Peru, Bolivia, Guyana, Brazil,
Paraguay) to Argentina (ca.

northern latitude
West Indies and in the PLE Islands (1.e.,
Isla Socorro and Isla Clarión
Zapoteca species occur in a variety of environ-
ments, ranging from open, arid or semiarid, scrub-
by vegetation types (e.g.. Z. media, Z. alinae, Z.
formosa subsp. mollicula, and Z. formosa subsp.
schottii) to the wet evergreen forests of Amazonian
Peru (Z. amazonica). Most populations of Z. por-
flavida and Z.
found in relatively wet, lowland habitats, generally
toricensis subsp. tetragona are
on disturbed sites. The greatest degree of diver-
sification has occurred in areas covered by sea-
sonal, tropical deciduous forests (sensu Breedlove,
1981). In addition to the species found in clearly
arid regions, most populations of eight species of
Zapoteca (Z. nervosa, Z. lambertiana, Z. filipes,
Z. mollis, Z. caracasana, Z. andina, Z. formosa,
and Z. tehuana) occur in tropical deciduous for-
ests. In addition, Z. portoricensis subsp. portori-
censis and subsp. pubicarpa primarily occur in
oak,
montane moist forests.
The occurrence of three of the four subgenera
middle-elevation pine-oak, or subtropical
of Zapoteca in South America (Zapoteca, Acu-
leata, and Amazonica), compared with only one
in Mexico and Central America, is probably a con-
sequence of the more ancient existence of Zapo-
teca in South America. Although only subg. Za-
poteca is represented in Mexico and Central
America, extensive diversification has taken place
at the specific and subspecific levels, especially in
Mexico. For instance, there are seven subspecific
taxa in Mexico (i.e., Z. portoricensis subsp. por-
toricensis, Z. portoricensis subsp. pubicarpa, Z.

Viewed from a global perspective, there are no
clear centers of species diversity in Zapoteca. The

bution of endemic taxa ee several regions
with high diversity (Fig.
Southern Mexico ee a -— Chiapas, includ-

of species and subspecies of Zapoteca. This rela-
tively small region, characterized by its remarkable
climatic and topographic diversity, contains seven
species, and if subspecies are taken into account,
the figure rises to eleven taxa (Z. media, Z. alinae,
Z. lambertiana, Z. portoricensis subsp. portori-
censis, Z. portoricensis subsp. pubicarpa, Z. por-
toricensis subsp. flavida, Z. tetragona, Z. formosa
subsp. formosa, Z. formosa subsp. rosei, Z. for-
mosa subsp. mollicula, and Z. tehuana). Four of
these are endemics (Z. alinae, Z. portoricensis
subsp. pubicarpa. Z. formosa subsp. mollicula,
and Z. tehuana). especially to dry areas of Oaxaca
and the arid valleys of the Pueblan- Oaxacan bor-
der region. The number of species and subspecies
of Zapoteca suddenly decreases from this center

Mexico, from Guerrero northwards, there are four

taxa (Z. tetragona, Z. formosa subsp. formosa,
Z. formosa subsp. rosei, and Z. formosa subsp.
schottii), decreasing to one in the northern portion.
Zapoteca media and Z. formosa subsp. formosa
are the only taxa that occur in the Central Plateau.
Along the entire Atlantic slope, from Tabasco to
Tamaulipas, together with the Yucatán Peninsula,
there are only five taxa (Z. lambertiana, Z. por-
toricensis subsp. portorte ensis, Z. portoric ensis
subsp. flavida, Z. tetragona, and Z. formosa subsp.
formosa). Zapoteca lambertiana is the only one
of these that is essentially endemic to this region.
In Central America, there are a total of eight
taxa (Zapoteca portoricensts subsp. portoricensis,
Z. portoricensis subsp. flavida, Z. mollis, Z. cara-

mosa subsp. formosa, and Z. formosa subsp. sal-
vadorensis). Diversity is quite uniform among the
different countries (Fig. 21). Zapoteca mollis and
Z. costaricensis are essentially endemic to Costa
Rica, although a disjunct population of the former
is known from Panama. Zapoteca formosa subsp.
salvadorensis is restricted to southern Guatemala
and El Salvador.
Six taxa of Zapoteca occur in the West Indies
(Z. nervosa, Z. portoricensis subsp. portoricensis,
flavida, Z.
subsp. caracasana, Z. formosa subsp. formosa,
Z. portoricensis subsp. caracasana
and Z. formosa subsp. gracilis). Generally only a
single species occurs on a particular island; how-
ever, in Hispaniola the four species, including the
endemic and morphologically distinct Z. nervosa,
occur together. Howard (1973) pointed out that
Hispaniola and Cuba are the most floristically di-
verse islands in the West Indies and that they show
great habitat diversity and highest percentage of
endemism (Hispaniola with 33% of endemic gen-
era). Zapoteca formosa subsp. gracilts is the sec-
ond endemic entity in the West Indies. It is pri-

Eleven taxa of Zapoteca occur in South Amer-
ica. The greatest diversity occurs in the tropical
Andean countries, Venezuela, Colombia, Ecuador.
Peru, and Bolivia, where populations are primarily
found in the foothills of the Andes, in the inter-
Andean valleys, and less commonly in the Amazon
Basin. As illustrated in Figure 21, the number of
taxa in each of these countries ranges from four
to six, with Colombia and Ecuador most diverse.
Perhaps the most remarkable biogeographical fea-
ture of this whole area is the occurrence of five
endemic taxa, which, excluding Z. caracasana
subsp. weberbaueri and Z. andina, comprise the
most highly advanced species in Zapoteca, each
with a large number of derived morphological char-
acters (i.e. Z. Andes; Z.
the Magdalena
aculeata, Ecuadorean
microc suada, Median Valley of
River; and Z. amazonica, Amazonian Pe ru). Out-
side this area, diversity is much lower, with one or
two taxa oceurring within Guyana, Brazil, Para-
guay, and northern Argentina (Fig. 21). Within

number of cases of gross geographical overlap are
known. However, only a few records of true sym-
patry exist: in the District of Tlacolula, Oaxaca,
plants of Z. alinae (H. Hernández & Ramírez
942) have been found intermixed with plants of Z.
formosa subsp. rosei (H. Hernández & Ramírez
943); in this same area of Oaxaca, Z. formosa
subsp. formosa has occasionally been found grow-
ing alongside Z. formosa subsp. rosei (H. Her-
nández & Torres 216, 217 and Magallanes 111,
113). Also, in the tropical deciduous forest of El
Chorreadero, Chiapas, Z. lambertiana (Breedlove
39694, H. Hernández & Ramírez 891) and Z.
portoricensis subsp. portoricensis (Breedlove
11889) have been collected; however, it is unclear
whether these are narrowly sympatric.
There are some presumed hybrids. For example,
in southern Guatemala and in southern Mexico, a
number of collections provide evidence for exten-
sive hybridization between Z. portoricensis subsp.
portoricensis and Z. tetragona; in southern Puebla
and northern Oaxaca, some plants with characters
intermediate between Z. media and Z. formosa
likewise suggest hybridization. In Guerrero popu-
lations of Z. formosa subsp. formosa and Z. for-
mosa subsp. rosei come into close proximity, and
there are a number of collections of probable hybrid
origin.
The predominance of allopatric distributions and
the apparent rarity of hybrids in Zapoteca suggest
that hybridization has played an insignificant role
in the evolution of the genus. The few cases of
strict sympatry may represent secondary contact
of previously differentiated populations. It could be
hypothesized that speciation in Zapoteca has pri-
marily resulted from genetic differentiation of geo-
graphically isolated populations.
There are wide disjunctions in the distribution
of Z. formosa subsp. formosa in South America,
from northern Colombia and Venezuela to Bolivia,
southeastern Brazil, and Paraguay (Fig. 44). As
elaborated below, its distribution was probably con-
tinuous across the Amazon Basin during the cool-
dry phases of the Pleistocene, when a drier and
presumably more suitable environment for this sub-
species was widespread (Ab'Sáber, 1982; Absy,
1982; Bigarella & Andrade-Lima, 1982; van der
Hammen, 1982; Prance, 1982). Zapoteca scu-

tellifera is closely related and is known from a few — et al., 1980), and also by the wide distribution of
disjunct populations in the Amazon Basin (Fig. 44).
Specialized characters in Z. scutellifera (e.g., scu-
telliform extrafloral nectaries, scandent habit) and
its presumed edaphic specialization suggest that it
was probably derived from Z. formosa subsp. for-
mosa. Zapoteca scutellifera could have been de-
rived from populations of Z. formosa subsp. for-
mosa that became isolated after the return to the
present-day, warm-wet climatic conditions.
This pattern. along with the patchy distributions
of dry-forest species like Z. E Tllana and
mollis, supports Gentry's (1979, 2) theory of
reverse refuges. This theory assumes that the pres-
ent discontinuities in the distribution of the dry
forests (dry forest refuges) coupled with the exis-
tence of geographically restricted, morphologically
differentiated dry-area populations, result from a
shift towards more mesic conditions after the cli-
matic deterioration in the Quaternary.
A second example of possible allopatric specia-
tion in Zapoteca involves the two members of the
highly specialized subg. Amazonica: Z. microceph-
ala and Z. amazonica. Zapoteca microcephala
is restricted to the Middle Magdalena River Valley,
whereas F amazonica occurs in Amazonian Peru

model of speciation for Zapoteca is the relatively
common occurrence of closely related taxa dis-

tions. This distribution pattern is shown by closely

During the past few years a considerable body

Furthermore, most species of Acacia (Acacieae)
are insect-pollinated (Bernhardt, 1983; pers. obs.);
however, bird pollination has been derived second-
arily in some Australian species of this genus (Ford
& Forde, 1976; Bernhardt, 1983; Kenrick et al.,
1983). In contrast, Parkia (Parkieae) is primarily
bat-pollinated (Baker & Harris, 1957; Hopkins,
1984), although a few species are pollinated by

High-energy pollination systems such as those
involving hawkmoths. birds, and bats are concen-
trated among the genera of the more advanced
tribe Ingeae (Cruden et al., 1976; Arroyo, 1981;
1983; Hernández, 1986a; unpublished
obs.). In the Ingeae, the transition from low-energy
Koptur,
insect pollination to high-energy systems, which
demand greater allocation to nectar and pollen, is
associated with inflorescence modifications. For in-
stance, connation of the staminal filaments to form
a tube and increase in number and length of the
filaments made it possible for the flowers to hold
larger quantities of nectar necessary to satisfy the
energy requirements of larger, homothermic pol-
linators. Similarly, changes in periodicities of nectar
and aroma production, nectar quality, and timing
of anthesis have enabled the plants to adjust to the
physiological and behavioral characteristics of par-
ticular pollinators.
Mimosoideae have a number of additional

lished reports concerning the reproductive biology
of the species here assigned to Zapoteca are vir-
tually nonexistent, and the present chapter is in-
tended to provide an account, based on my own
observations, of some of the reproductive features
of these plants.
METHODS
Nectar volumes were measured with calibrated
micropipets, and sugar concentrations were deter-
mined using a temperature-compensated Erma hand
refractometer. In a few cases, when the flowers
were very small, a syringe was used to extract the
nectar from the staminal tubes. All measurements
were made in the greenhouse early in the morning
in order to estimate the total amount of nectar
produced per flower. Between four and ten indi-
viduals per population were examined. It is quite
possible that the results in Table 6 might be lower
volumes than would be found in the wild, since it
has been shown that nectar volumes and sugar
concentrations may be significantly lower in plants
growing in greenhouse pots compared with wild
plants (Cruden & Hermann, 1983). However, they
allow species comparisons.
Field observations on flower visitors were carried
out continuously during the first three to five hours
of anthesis. Since all Zapoteca species flower at
night, the behavior of flower visitors was observed
with the aid of a head lamp. In most cases, visitors
were successfully collected with insect nets. Insect
voucher specimens are deposited in the Entomo-
logical Collection at the Instituto de Biologia,
The number of ovules per gynoecium was de-
termined by squashing fixed ovaries in a drop of
Alexander's stain (Alexander, 1969); the ovaries
were examined with a compound light microscope
within 15-20 minutes after staining. Sex expres-
sion was characterized for each population by dis-
secting fixed flowers and counting the proportion
of hermaphrodite and female-sterile flowers in each
inflorescence. Self-compatibility was assessed on
plants growing in the greenhouse using the tech-
niques outlined by Bawa (1974). Pollinations were
accomplished using a fine brush within four hours
of the beginning of anthesis, once the anthers were
dehiscent. Anther dehiscence was determined by
touching the anthers with a clean microscope slide;
a large number of polyads on the slide revealed
open thecae. Given the small size of the flowers,
the inflorescence was taken as a unit in the polli-
nation treatments. In every population, a deter-
mined number of inflorescences were artificially
eross- and self-pollinated, and several additional
inflorescences were left untreated (open) to test for
autogamy. Due to the difficulty involved in emas-
culating the delicate flowers of Zapoteca, the pos-
sibility of apomixis was not tested. For the cross-
pollinations, mixtures of polyads from several in-
dividuals were used whenever possible. For the
self-pollinated inflorescences, the pollen donor was
taken from the same inflorescence or from other
inflorescences in the same individual; therefore, a
great number of these flowers were geitonoga-
mously pollinated. Treated inflorescences were
marked with hanging labels. As the greenhouse was
insect-free, inflorescence manipulation was mini-
mized by avoiding the need to bag inflorescences.
Sample size varied from two to nine individuals per
population. After each treatment, brushes and hands
were sterilized with ethanol. Since pod abortion
occurs in Zapoteca species at several stages of
pod development, the resulting pods were counted

FLOWERING PHENOLOGY
Although it is difficult to characterize the phe-
nological behavior of a given species throughout
its range, I shall attempt to draw some generali-
zations about the flowering patterns in Zapoteca.
This discussion is based primarily on species re-
stricted to Mexico and Central America. In wide-
ranging species such as Z. tetragona, flowering
times vary from one region to another. This species,
which usually grows in secondary vegetation de-
rived from lowland tropical wet forests, flowers
mostly during the dry season; nevertheless, in the
Mexican state of Morelos, where a more seasonal
climate exists, the populations flower primarily dur-
ing the rainy season. Zapotec a portoric ensis subsp.
flavida, which grows in wet habitats, also flowers
during the dry season. By contrast, the species
growing in drier habitats (thorn forests, tropical
deciduous forests, and tropical semideciduous for-
ests) tend to flower predominantly during the sec-
ond half of the rainy season (e.g., Z. formosa, Z.
lambertiana, Z. media, Z. alinae). The species
from drier areas have shorter, more synchronized
flowering periods than species living in wetter hab-
itats (e.g., Z. amazonica and Z. tetragona), which
continue to produce flowers for longer periods.
Finally, Z. portoricensis subsp. portoricensis, which
generally grows in montane mesophyllous forests
(terminology following Rzedowski, 1978), also flow-
ers in the wet season.

"multiple-bang" strategy described by Gentry
(1974) for tropical Bignoniaceae. It differs, how-
ever, in that the flowering is not synchronized among
the different individuals that make up a given pop-
ulation of Z.
of this strategy is that these flowering bursts pro-

Anthesis and the process of flower presenta-
tion. Field and greenhouse observations have
shown that species of Zapoteca display predictable
flowering mechanisms. All members of the genus
exhibit nocturnal anthesis and a remarkable syn-
chrony in floral behavior during flower presenta-
tion. Usually the filaments of all the flowers in a
head become erect in a springlike fashion late in
the evening (ca. 17:00-18:00 hours), during the
last two hours of daylight. Subsequently, when the

is constant in a given species of Zapoteca and thus
is of taxonomic value. The filaments may be white
(e.g., Z. alinae, Z. portoricensis, Z. tetragona),
red-purple (Z. lambertiana), or a combination of
white in the basal half and pink or red-purple in
the distal half (e.g., Z. amazonica, Z. caracasana,
Z. media). The widespread Z. formosa shows some
geographical variation in filament color, and the
recognition of subspecies within this species is based
in part on this feature. This character is nearly
always stable at the population level in Z. formosa;
however, in a population observed in eastern Oa-
xaca a mixture of plants with white (11. Hernández
& Torres 216) and white pink filaments (/7. Her-
nández & Torres 217) turned up. Similarly, in-
dividual plants of Z. tehuana with either white or
white/pink filaments were observed in a
house population (/7. Hernández 950). The flowers

of all species of Zapoteca produce a delicate, sweet

of Z. tetragona (the species with essentially the
most massive flowers in the genus), the nectar
volumes were substantially higher (Table 6). The
nectar of Zapoteca species has rather low sugar
concentrations, ranging from 13.9 to 20.3%. The
nectar volumes and sugar concentrations in the
flowers of Zapoteca species reported here agree
with those reported by Opler (1983) and Baker &
Baker (1983) for settling moth-pollinated flowers.
FLOWER VISITORS
Inflorescences Zapoteca species are well
adapted for pollination by moths. Field observations
conducted in ten different populations representing
five species of Zapoteca clearly showed that the
flowers are consistently visited and pollinated by a
variety of settling moths, mostly of families Noc-

cences after some nectar had accumulated in the
staminal tube and after floral fragance was detected
by observers. Moths usually landed in the upper
part of the inflorescence, where the underside of
their bodies contacted the anthers and the stigmatic
surfaces (Fig. 27). Moths generally moved from
one part of the inflorescence to another in search
of nectar, and the length of time they remained
on an inflorescence was often up to 20-30 minutes.

number of species of smaller moths were excluded
because they were considered to be ineffective pol-
linators.
Many species of moths were observed to exploit
the nectar of Z. tetragona (population J) illegiti-
mately. They extracted nectar by standing on the
peduncles without touching the anthers and stig-
mas. However, five species of moths were observed
to visit the flowers of this species legitimately; among
these, Palpita flegia (Fig. 27) and Diaphania
jairusalis may be considered the primary polli-
nators on the basis of their abundance (Table 7).
The color of the wings of these two species is
strikingly similar to that of the white filaments of
Z. tetragona. In contrast, the nectar robbers, along
with the few other occasional pollinators, have wings
with a variety of color patterns.
Although inflorescences of Zapoteca species dis-
play the typical syndrome of characteristics asso-
ciated with hawkmoth pollination (Faegri & van
der Pijl, 1979), hawkmoths were rarely observed
as visitors. During the course of my observations,
only two hawkmoths were observed, one visiting
the flowers of Z. formosa (population C) and one
on Z. lambertiana (population J). A possible ex-
planation for this is that the individual flowers pro-
duce rather small amounts of nectar, making the
visits energetically unprofitable to hawkmoths. Ac-
cording to Opler (1983) and Haber & Frankie (in
hawkmoth-pollinated flowers usually pro-
duce much greater amounts of nectar (maximum
available nectar = 130.5 ul; 1983)

Two unidentified species of crab spiders (Ara-

visiting the inflorescences of Z. formosa subsp.
rosei and Z. portoricensis subsp. portoricensts.
These light-colored spiders would be inconspicuous
on the inflorescences of Zapoteca species, where
their cryptic coloration permits them to prey on
flower visitors. Given that the spiders occurred in
very low numbers, their negative impact on the
reproductive potential of the plants is probably

POLLINATION RELATIONSHIPS
MI species of Zapoteca have very delicate, cup-
shaped stigmas, and as indicated. elsewhere (Her-
nández, 1986a), the concave area of receptivity is
so narrow that only a single 16-grained polyad can

sidering that the likelihood of a pollen unit reaching
the stigma is directly proportional to the receptive
(Cruden & Miller- Ward, 1981),
one might anticipate that the chances of suecessful
area of the stigma
pollination in species of Zapoteca are rather low.
As pointed out earlier, however, the settling moths
that were recorded visiting species of Zapoteca
normally remain on the inflorescences for consid-
erable periods of time. The chances of successful
pollination are also affected by the time the body
of a particular pollinator makes contact with the
stigma; therefore, the relatively long visits by set-
tling moths compared with hawkmoths might be
understood as a compensating factor to the intrinsic
reaching the stigma in
low chances of a polyac

ported by Kenrick & Knox (1982) and Knox &
Kenrick (1983) for species of Acacia. In this ge-
nus, however, the range of variation in the ratio
of number of grains to number of ovules is some-
what broader than in Zapoteca, but the species of
Acacia with 16-grained polyads also have ratios
approaching one (Kenrick & Knox, 1982). In Cal-
liandra (sensu Hernández, 1986a) ratios also vary
around one; however, in several species of the
highly advanced ser. Racemosae,
ovules greatly exceeds the eight grains found in
the polyads (Nevling & Elias, 1971; Cruden, 1977;
Hernández, 1984, and unpublished results). This
reduction in the ratio of number of grains to number
of ovules is probably associated with the highly
modified fungiform, discoid, or capitate stigmas
found in Calliandra, which have a greater area of

BREEDING SYSTEMS
Sex expression. In species of Zapoteca, sex
expression and genetic self-incompatibility systems
are the primary components of the breeding system
that affect pollination and fertilization. Analysis of
the inflorescences of several species has shown that
morphologically expressed andromonoecy resulting
from abortion of the gynoecium is widespread in
the genus (Table 9). Functionally male flowers with
an aborted gynoecium are irregularly distributed
among populations. Generally, individual plants have
inflorescences with varying proportions of her-
maphroditic and functionally male flowers; how-
ever, individuals with inflorescences composed en-
tirely of hermpahroditic flowers are not uncommon.

The ratios of hermaphroditic to female-sterile
(functionally male) flowers change during the course
of the flowering season in individual populations.
Therefore. the figures provided in Table 9, which
correspond to a single stage of the flowering cycle
in each population for which data are enumerated,
do not reflect the actual proportions of the two
flower tvpes.

interspecific variation in sex expression among the
'able 9 indicates a great amount of intra- and
species of Zapoteca. The ratios of hermaphroditic
to female-sterile flowers varied from 0.4 to 77.5
in the studied populations. Thus far, I have been
unable to establish any correlation between the
nature of sex expression and factors such as alti-
tude, frequency of pollinator visitation, and incom-
patibility systems. Nevertheless, a planned, detailed
analysis of temporal variation in the ratios of her-
maphroditic to female-sterile flowers in natural pop-
ulations would probably contribute significantly to
understanding this reproductive phenomenon.
Incompatibility systems. The results of the
incompatibility experiments show that of the five
species studied, only Z. tetragona is clearly ge-
netically self-incompatible, as indicated by the in-
ability of the flowers to set pod following the self-
and open-pollinated treatments in the two popu-
lations (Table 10). In contrast, plants of the two
populations of Z. formosa that were studied proved
to be genetically self-compatible, and those from
one additional population (H. Hernández 959) were

Incompatibility studies on the remaining species

genetically self-compatible, at least in part. In both
Z. media and Z. alinae, pod set was significantly

pollinated inflorescences developed no mature seeds.
In contrast, the pods set in untreated inflorescences
produced a relatively low average number of seeds
per pod (2.8), which indicates some degree of ge-
netic self-compatibility in Z. portoricensis. Pre-
suming that there was no accidental transfer of
polyads among the untreated plants, the individuals
of all three species tested were at least in part
genetically self-compatible.
CONCLUDING REMARKS
Zapoteca species, are relatively consistent in
several important features of reproductive biology.
All the observed species exhibit nocturnal anthesis.
The small flowers are organized in compact, cap-
itate inflorescences, and there is remarkable syn-
chrony among the flowers of a given capitulum in
all the stages of flower presentation and in the
patterns of aroma and nectar production. This sug-
gests that ecologically the spherical capitula act as
units of attraction. The particular combination of
morphological and behavioral features in the inflo-
rescences of species of Zapoteca is well adapted
for pollination by settling moths. Moreover, the
remarkable morphological correlation between the
stigmas and the polyads in Zapoteca, along with
the specific behavior of its pollinators, reflects a
highly organized reproductive system. Reduction
in the number of ovules in each ovary increases
the reproductive efficiency of these species, giving
a single polyad the potential of fertilizing all the
ovules in an ovary. In other words, the high cor-
relation between the number of ovules in an ovary
and the number of pollen grains in a polyad is a
reflection of the high probability of the ovules being
fertilized by the pollen grains contained in a single
polya
According to Arroyo (1981), about half of the
genera of Mimosoideae are andromonoecious; this
condition occurs especially in taxa with capitate
inflorescences. The results presented in Table 9
indicate that andromonoecy is widespread in Za-
poteca, and the presence of a vestigial gynoecium
in functionally male flowers strongly suggests that
andromonoecy is derived from hermaphroditism in

In natural populations, the vast majority of the
capitula abscise after anthesis. Even in the re-
maining capitula, only a fraction of the fertile ova-

Thus, most of the flowers produced in Zapoteca

cence and as pollen donors (Stephenson, 1981,
and references therein)
Rather than being limited by pollinator activity,

probably affected by energetic,
inflorescences of the Zapoteca species are
and certainly by
physical architectural constraints, which set the
upper limit for maximum pod production. In this
connection, Stephenson (1981) reviewed the avail-
able evidence and suggested that “an upper limit
to the number of pods that set is usually determined
by resources rather than the number of morpho-
logically female flowers, and . . . natural levels of
pollination exceed pod set in many species." In
this context, the adaptive nature of female sterility
can be understood: given the lower pod set in
Zapoteca populations, a reduction in the number
of functional gvnoecia in an inflorescence would
not reduce pod set. Vestigial gynoecia must be
energetically less expensive to produce than the
arger, functional ones. Thus, andromonoecy should
be understood as a system that makes more efficient
use of reproductive energy without compromising
pollinator attraction (Ruiz & Arroyo, 1978; Pri

TAXONOMIC HISTORY OF ZAPOTEC AL
Analysis of several critical characters of the
neotropical species of Calliandra, a large genus
currently undergoing revision (Forero, 1984; Her-
nández, 1984), showed that Calliandra sensu Ben-
tham apparently is polyphyletic. Consequently, the
species of Bentham’s Calliandra ser. Laetevi-
rentes were recognized as generically distinct (Her-
nández, 1986a). For this natural group | proposed
the name Zapoteca.
Mimosa portoricensis Jacq. (— Zapoteca por-

sana) were the first species to be published of what
is now Zapoteca. They were described in 1791 on

This a plastic. species is wide-
spread in dry and semiarid regions of central and
northern Mexico. It can be readily distinguished
from its close relative Z. alinae primarily by having
larger, white/ purple-red filaments, usually shorter
stature, and copious branching. In addition, the
leaflets of Z. media are usually broader than those
of Z.

nández & Torres 15%, Moore 1383), populations
of plants with hairy leaflets seem to be geograph-
ically segregated from the glabrous ones.
The distributions of Z. media and Z. formosa
approach one another closely in some areas of
northern Oaxaca and southern Puebla, but indi-
viduals from these species are not known to grow
together. There is evidence of hybridization, which
results in morphological intergradation between the
two. Plants collected in the area of Acatlán de
Osorio and Tehuitzingo, Puebla (11. Hernandez &

This endemic species, which is relatively con-
sistent morphologically, is closely allied to Z. media
by its l- to 3-jugate pinnae, small, numerous leaf-
lets, and habitat preferences. It can be readily
distinguished from that species by the usually more
slender stems, branchlets, and peduncles, narrower
and consistently glabrous leaflets, and primarily by
its flowers with shorter, white filaments. Zapoteca
alinae is allopatric with Z. media. Its distribution
overlaps at the east of its range (H. Hernández &
Torres 942) near Totolapan, Dist. Tlacolula, with
that of Z. formosa subsp. rosei (H. Hernández &
Torres 943), but no evidence of hybridization was
observed there.

Zapoteca lambertiana can be readily distin-
guished from other species of subg. Zapoteca pri-
marily by its much thinner pods with undulate
surfaces and thinner margins, and specifically from
Z. portoricensis by its red-purple filaments. Extra-
floral nectaries between the pinnae in a single spec-
imen (Dressler 2006, GH) and presumed similar-
ities in the texture of the pods suggest a bu
close relationship between this species and Z.
lipes. Leaf indument is very variable in Z. "a
bertiana: it varies at both intra- and interpopu-
lation levels and does not seem to follow a
geographical pattern.
There is no morphological differentiation among
the disjunct populations that occur over the ex-
tensive geographical range of Z. lambertiana. It
is likely that such discontinuities are of recent
origin. Perhaps they resulted from tropical dry

forest fragmentations that occurred in the tropics
subsequent to the Pleistocene glaciation, after the
present wetter conditions originated disjunctions in
the formerly extensive and continuous areas cov-
ered by tropical dry forests.

Distribution. This species has been collected
at a few localities in the Brazilian states of Goiás
and Minas Gerais, where it is commonly associated
with cerrado vegetation at 950 m elevation. It was
incorrectly reported by Macbride (1943) from Peru
and by Cárdenas (1974) from Venezuela.

Zapoteca filipes is probably closely related to
Z. lambertiana as judged by the vegetative char-
acteristics of these species, especially by the com-
mon possession of membranous pods. Extrafloral
nectaries, universal in Z. filipes, are occasional in
Z. lambertiana. Zapoteca filipes can be readily
distinguished from the remaining species of subg.
Zapoteca by the cylindrical glands on the petiole,
rachis, and rachillae.

Zapoteca portoricensis as circ umscribed here,
consists of three rather variable subspecies:
toricensis, pubicarpa, and flavida. Each has a
few distinguishing, variable characters (Table 12),
although they intergrade and overlap. Consequent-
ly, these subspecies are defined on the basis of
combinations of characters. Viewed in a local con-
text, each subspecies might be accorded specific
rank; however, a synthetic analysis of all available
material reflects the absence of strong morpholog-
ical discontinuities distinguishing them.
The three subspecies of Z. portoricensis have
distinct habitat preferences: subsp. portoricensis
occurs primarily in relatively wet, mid- to high-
altitude habitats; subsp. flavida is found wet,
lowland areas: and subsp. pubicarpa occurs in dry,
in the West Indies,
subsp. portoricensts usually occurs in much drier,
mid-altitude areas. However,
low, sometimes coastal, habitats.

species has been collected in several relatively lo-
calized areas: 1) Atlantic slopes of the Sierra Madre
Oriental, in the states of Hidalgo, Puebla, and San
Luis Potosi, and the eastern portion of the Trans-
verse Volcanic Belt in Veracruz; 2) Sierra Madre
del Sur, including parts of the Mixteca Region in
Oaxaca; 3) Sierra Madre of Chiapas, and the Chia-
This widespread sub-
pas and Guatemala Highlands; and 4) W est Indies,
in Jamaica, Hispaniola, and Puerto Rico (including
some of the Virgin Islands). Disjunctions occur in
the Sierra de Tamaulipas, Tamaulipas; Temascal-
tepec, State of México; and in Honduras, Nica-
ragua, Costa Rica,
lection from Nova Friburgo, Rio de Janeiro, Brazil
and Panamá. There is a col-
(Curran 655). which was probably obtained from
cultivated plants. This subspecies has usually been
collected in mountain areas of moderate to rela-
tively high altitude (800-2,100 m), in plant com-
munities such as oak, pine, pine-oak, temperate
deciduous, wet montane cloud, and montane rain
forests, especially in secondary habitats. Never-
theless, in some areas such as the Huasteca in the
states of Hidalgo and San Luis Potosi, Mexico,
populations usually occur at lower elevations,
reaching as low as 165 m. Similarly, plants from
the West Indies usually inhabit low elevation areas,
down to sea level, with a much drier climate.

Acacia venusta Willd. (Enum. Hort. Berol.
1809) has been traditionally. included
synonymy under Z. (Calliandra) portoricensis,
which is probably incorrect. The only material |
have been able to relate to this name is a specimen
at the Willdenow Herbarium (Cat. No. 19143),
Bot. Berol. W.." as
indicated by a handwritten note in the lower right

margin. The brief description provided in the orig-
inal publication of this species is a replica of the
specimen label, which probably was handwritten
by Willdenow himself, judging by the style of hand-
writing (Burdet, 19). This specimen consists of
two leaves, with the pinnae widely separate from
each other, and rather few pairs of leaflets per
pinnae. Because of the lack of flowers or pods, it
is not possible to relate this specimen to Z. por-
toricensts.
Zapoteca portoricensis subsp. portoricensis, as
delimited here, is an extremely variable, broadly
defined subspecies, the most variable within the
species. It can be distinguished from closely related
subsp. pubicarpa by its glabrous pods, usually
smaller flowers, glabrous to ciliate calyx teeth, and
12). It differs from
subsp. flavida by its erect habit, usually smaller
usually longer peduncles (Table
and more numerous leaflets, usually larger flower
parts, and smaller pods (Table 12).
Perhaps the most highly variable character 1
subsp. portoricensis is the degree of pubescence
of its vegetative structures. Plants range from en-
tirely glabrous or glabrate to having branchlets and
leaf parts densely villous with long tawny hairs.
This tvpe of variation occurs at both inter- and
intrapopulational levels, and, consequently, is of
little taxonomic value. There are geographical pat-
terns in the expression of this character. One ex-
treme occurs in Veracruz, and to a lesser extent
in Hidalgo and Chiapas, where there is a prevalence
of collections with densely villous branchlets and
leaves. The other extreme occurs in San Luis Po-
tosi, Tamaulipas, and Central America, where gla-
brous or sparsely villous leaves and stems predom-
inate. In the West Indian plants, the leaflets are
consistently. glabrous, but the branchlets may be
villous or glabrous.
Other variable characters in Z. portoricensis
subsp. portoricensis are the size and number of
pairs of leaflets per pinna. Most plants from the
Sierra Mixteca, Sierra Madre del Sur, and Sierra
Madre de Chiapas, in the states of Oaxaca and
Chiapas, Mexico, are characterized by pinnae with
smaller, more numerous (to 67) pairs of leaflets
usually densely distributed along the rachilla, giving
the pinnae a feathery aspect. Plants with small,
numerous pairs of leaflets per pinna are also found
in Central America. In Oaxaca, plants with leaves

Missouri Botanical Garden
of this sort also tend to have larger flowers and
usually larger stipules. However, these characters
have been found in numerous collections from dif-
ferent regions (e.g.. Veracruz, Puebla, Hidalgo),
where they occur in plants that do not have feath-
ery leaves like the ones in Oaxaca, so that there
is no definite geographical pattern and no basis for
recognizing additional infraspecific taxa. In con-
trast, many of the plants from the West Indies
have larger and less numerous leaflets, thereby
resembling subsp. flavida.
e vast majority of collections of Z. portori-
censis subsp. portoricensis have terete branchlets;
however, plants with four-angled branchlets, a
characteristic diagnostic for Z. tetragona, are not
uncommon in some regions. Some of these plants
may be the result of hybridization between subsp.
portoricensis and Z. tetragona. These two taxa
are generally ecologically isolated in Central Amer-
ica and southern Mexico, where their geographical
ranges overlap. In these regions, populations of
subsp. portoricensis are found primarily in mon-
tane cloud forest or similar habitats, whereas those
of Z. tetragona occur in warmer lowland habitats.
Populations with four-angled branchlets are most
frequent in Guatemala, where these two taxa come
into close proximity and in some cases are probably
strict sympatric. A number of Guatemalan collec-
tions of subsp. portoricensis have four-angled
branchlets, although sometimes this characteristic
is expressed only distally, or is less marked than
in typical. Z. tetragona (e.g., Molina & Molina
12287, Standley 86574, 87132, Steyermark
34256, Williams et al. 12100, and others). Sig-
nificantly, these plants are derived from areas where
Z. portoricensis subsp. portoricensis and Z. tetra-
gona approach each other, as for example, in the
areas of San Juan Chamelco-Cobán-San Pedro
Corchá, Departamento de Alta Verapaz; Colomba
Santa Maria de Jesús, Departamento de
lenango;
Ipala-Comatán, Departamento de Chi-
quimula; and Escuintla-San Vicente Pacayas,
Departamento de Escuintla. Individuals with four-
iden branchlets also occur in some other regions
(e.g.. Orizaba-Cordoba, Veracruz, Chiapas), and
even in areas where Z. tetragona does not occur,
such as Haiti.
West Indian populations often differ from those
on the mainland in some characters, possibly the
result of the smaller gene pools in insular popu-
lations and the selective effects of local climates.
In many of the plants collected in the West Indies,
the leaflets are comparatively larger, approximat-
ing those of Z. portoricensis subsp. flavida. Ja-
maican specimens are characterized by smaller
(4.5-6 cm long) pods and by usually smaller, black
seeds with regular pleurograms, as compared with
the mainland populations. In addition, some of the
plants from this island have | -2-jugate pinnae with
fewer pairs of leaflets.
Zapoteca portoricensis subsp. portoricensts and
its close relative Z. caracasana subsp. caracasana
co-occur on Hispaniola, although it is unclear
whether they really grow together. Here, as else-
where in the West Indies, most plants of subsp.
portoricensis differ from mainland populations in
having calyces with the teeth lanceolate to linear
lanceolate, a characteristic of Z. caracasana. In
some cases, the identification of herbarium speci-
mens is troublesome if information concerning habit
and filament color is not provided. However, there
are several diagnostic characters for each taxon
(Table 13, while comparing the two species, applies
to the two subspecies discussed here). Zapoteca
caracasana subsp. caracasana differs from Z.
portoricen SIS subsp. portoricen sis in its prostrate/
scandent habit, smaller flowers, white /red-purple
filaments, and by the frequent occurrence of pseu-
dopaniculate inflorescences with more slender pe-
duncles. The relationships between these two taxa
are discussed further under Z. caracasana.

Zapoteca portoricensis subsp. pubicarpa is
closely related to subsp. portoricensis, from which
it can be distinguished primarily by having puber-
ulent pods, villous calyx teeth, larger flowers, and
usually shorter peduncles (see Table 12). The ova-
ries are glabrous, but pubescence becomes evident
soon after the pods start to develop. The charac-
teristics used to define this subspecies are not dis-
continuous with those of subsp. portoricensis.
However, the particular combination of morpho-
logical characters defining subsp. pubicarpa is dis-
tinctive and appears to be relatively constant
throughout its range. This and its. biogeographic
consistency justify its recognition as a separate
subspecies.
The pubescence of the pods is the main diag-
nostic character for this subspecies. Nevertheless,
hairy pods have been found in two collections of
Z. portoricensis subsp. portoricensis from Nica-
ragua (Laguna 333, Moreno 8272). These plants,
however, have smaller flowers and longer peduncles
than are characteristic of subsp. pubicarpa:; they
clearly fall within the limits of subsp. portoricensis.
Flower size is variable in subsp. portoricensis, with
large (calyx ^ 2-3 mm long. corolla — 6-8 mm
long) flowers found in plants throughout the range
of this subspecies: such flowers, however, are rarely
as large as those of Z. portoricensis subsp. pubi-
carpa, and the plants on which they occur never
have the hairy pods or short peduncles character-
istic of subsp. pubicarpa.

This subspecies can be easily distinguished from
subsp. portoricensis and pubicarpa by its scandent
habit, larger, usually less numerous leaflets, and
usually larger pods. In addition, subsp. flavida
primarily grows in habitats associated with lowland
tropical forests, whereas the two other subspecies
have been collected chiefly in subtropical, mid- to
relatively high-altitude habitats. Zapoteca porto-
ricensis subsp. flavida can be distinguished from
^. caracasana by having larger leaflets, flower
buds constantly glabrous, deltate-triangular calyx
teeth, white filaments, and larger pods. The capit-
ula are arranged in pseudopanicles only occasion-
ally in Z. portoricensis subsp. flavida; this is a
very common condition in Z. caracasana.
Zapoteca portoricensis subsp. flavida is rela-
tively constant morphologically throughout its wide
range; however, a number of collections from South
America have a combination of characters that
differ from those of the Mexican and Central Amer-
ican plants. Characteristics of a collection from
Colombia (Philipson et al. 1418) suggest mor-
phological intergradation between Z. portoricensis
subsp. flavida and Z. caracasana: narrowly tri-
angular to linear-triangular stipules, leaflets 8 X
2 mm, numerous (to 36) pairs of leaflets per pinna,
capitula arranged in elongate pseudopanicles, calyx
with linear-lanceolate teeth, and white filaments.
An almost identical situation is displayed by most
of the Brazilian collections of Z. portoricensis subsp.
flavida (Andrade-Lima 70-5777, Ducke 1517,
16051, Fróes 30295, Guedes 378, Hatschbach
34270, Pickel 2430, Tavares 754). Here, several
of the vegetative and reproductive characters di-
agnostic of either Z. portoricensis subsp. flavida
or Z. caracasana intergrade in particular popu-
ations.
Although it is not known whether Z. portori-
censis subsp. flavida and Z. caracasana ever ac-
tually grow together in specific habitats, they have
been collected in comparable microhabitats (e.g.,
river banks, shady sites, and thickets), which raises
the possibility of hybridization. Populations of Z.
caracasana, however, occur more commonly in
drier habitats than do those of Z. portoricensis
subsp. flavida. The distributions of these two taxa
overlap only in the area of the Andes, where there
is much local microhabitat differentiation.
Collections from Bolivia have some characters
that do not correspond with those commonly found
in individuals of Z. portoricensis subsp. flavida.
For instance, the filaments are reported to be white-
pink, instead of white, in Steinbach 822. The calyx
in almost all the Bolivian collections has lanceolate

Further, the filaments are white in Z. portoricensis
subsp. flavida, but white in the basal half and
ochroleucous in the distal half in Z. mollis (Grayum
1162, 4290). (It would be desirable to check more
living individuals for this feature.) Contrasted with
Z. portoricensis subsp. flavida, which is commonly
found in thickets in wet lowland habitats (e.g., along
ater courses and near ponds), populations of Z.
mollis usually occur in relatively dry habitats. With
the exceptions of Z. formosa subsp. salvadorensis,
Z. caracasana subsp. weberbaueri, and Z. por-
toricensis subsp. pubicarpa, this is the only species
in the genus with hairy pods.
In addition to the few collections of this species
from Costa Rica, there is a collection from Santa
Cruz, near Panama City (Arroyo 37), which in-
dicates a disjunction in its range. This collection,
with immature pods, matches the plants collected
in Costa Rica well. Recent attempts (1984) to re-
collect from this population have been unsuccess-
ful, presumably due to widespread destruction of
natural habitats in this part of Panama.

Zapoteca caracasana is closely related to Z.
portoricensis, and these two species have been
merged at times. For instance, Bentham (1844
considered Z. (Calliandra) caracasana as a syn-
—
onym of C. portoricensis, although subsequently,
1875),
he recognized them as distinct species. Later,
Woodson & Schery (1950) treated Calliandra
portoricensis as a synonym of C. caracasana. The

tification of herbarium specimens is admittedly dif-
species are outlined in

guished from Z. portoricensis by its presumably
constant scandent or prostrate habit, usually small-
er leaflets, and capitula with more slender pedun-
cles, which are usually arranged in pseudopani-
culate inflorescences, a condition rarely found in
Z. portoricensis. Observations on cultivated ma-
terial and information from herbarium specimens
suggest that the scandent/prostrate habit of Z.

caracasana is widespread throughout its range;
however, it is uncertain whether it is characteristic
of all the populations or if erect plants occasionally
occur, as indicated by label information on a few
specimens. Within Z. portoricensis, the scandent
habit occurs only in subsp. /lavida. There are,
however, important differences in growth habit be-
tween that entity and Z. caracasana: cultivated
specimens of of Z. caracasana (H. Hernández
961) had extremely short primary stems, usually
ds rise to drooping, very elongate branchlets
10 cm above the soil level, while those of Z.
Mises subsp. flavida develop very long,
flexible primary stems, sometimes reaching several
meters before giving rise to secondary branches.
The flowers of Z. caracasana are generally
smaller than those of Z. portoricensis, and the
calyces are consistently deeply divided to the base,
with the teeth lanceolate to linear-lanceolate. In
addition, the two species are easily distinguished
by their filament colors (Table 13) and by the
usually smaller pods in Z. caracasana. Pod size,
however, is highly variable in Z. portoricensis.
Although the degree of pubescence of stems and
leaves is extremely variable in Z. caracasana and
in Z. portoricensis, the branchlets of the former

Zapoteca caracasana consists of two closely
related subspecies: caracasana (with glabrous pods)
and weberbaueri (with canescent or pubescent
pods). As in the other taxa of Zapoteca with pu-
bescent pods (Z. mollis. Z. portoricensis subsp.
pubicarpa, Z. formosa subsp. salvadorensis), the
ovaries of Z. caracasana subsp. weberbaueri are
glabrous, and the hairs of the pods presumably
develop after fertilization. However, the ovaries in
this subspecies occasionally have a few hairs.

This epithet has traditionally been associated
with Z. portoricensis (Macbride, 1943), perhaps
because of the superficial similarities between this
iod ies and Z. caracasana. The type material of
“Calliandra weberbaueri, however, has a num-
ber of features suggesting its inclusion. within. Z.
caracasana. For instance, the calyx is deeply di-
vided, and the filaments are "white; pinkish-red

those observed in many other collections of Z.

Zapoteca tetragona is closely allied to Z. por-
toricensis but can be readily distinguished pri-
marily by having conspicuously tetragonal branch-
lets, larger corollas, and longer filaments. Despite
the opinion of Woodson & Schery (1950), who
suggested that Z. tetragona (Calliandra tetra-
gona) is distinguished “unnaturally” by its tetra-
gonal branchlets, implying that it is not differen-

Zapoteca andina is
in the
provinces of Azuay and Loja, Ecuador; the de-

Zapoteca andina resembles Z. tetragona in
althoug
branchlets are sometimes visibly four- miris only
most of its vegetative features, the
in the youngest parts. It differs from Z. tetragona
primarily by having smaller, triangular, descending
or depressed, auriculate stipules and by having
narrowly oblong calyx teeth, smaller floral dimen-
sions, and white/red-purple filaments. Available
collections of Z. andina do not reveal the habit,
and it is uncertain whether plants of Z. andina
are erect shrubs or low, subprostrate or prostrate
shrubs, as suggested by the aspect of some of the

Zapoteca formosa subsp. formosa is the most
widespread and morphologically variable subspe-
cies within the species. Fourteen names have been
published that fall within the boundaries of this
subspecies as | have defined it; most of them have
been based primarily on regional variations in leaf-
let morphology and vestiture. These characters,
along with the size of the flower parts and pods,
are highly variable at an inter- and intrapopulation
level, especially in the Mexican and Central Amer-
ican populations, and thus they are not useful tax-
onomically. Perhaps the most variable character
is leaflet size, but the variation does not correspond
to a geographical pattern. Á similar situation occurs
with variation in leaflet vestiture; plants with short-
pubescent or villous leaflets occur in the same areas
as plants with glabrous leaflets throughout most of
the range. In addition there is continuous variation
in leaflet apex morphology, ranging from rounded
to acute. Plants from the southern limits of this
subspecies are comparatively consistent. morpho-
logically. In this area, they usually have medium
to relatively small leaflets, and the number of pairs
of leaflets per pinna is quite regular.
The entity most closely related to Z. formosa
subsp. formosa appears to be the Central American
subsp. salvadorensis, which is distinguished by its
densely pilose pods. Zapoteca formosa subsp. for-
mosa is consistent in having glabrous pods, al-
though in El Salvador and Venezuela, plants with
glabrate pods have been collected. In a few col-
lections of subsp. formosa from Oaxaca, Jalisco,
Honduras, Venezuela, and Cuba, the pods are pi-
lose or sparsely pilose when very young, but soon
become glabrou
Zapoteca Pm subsp. formosa also appears
closely allied to subsp. rosei, from which it differs
by having white or white-green filaments (Table
4). Plants of subsp. formosa also usually have
larger leaflets and are generally more robust than
those of subsp. rosei. In a number of instances,
however, the identification of these two subspecies
is troublesome if flowers are not available or if
filament color is not known. In some areas of the
Mexican Pacific slope, especially in the state of
Guerrero, where these two subspecies presumably
occur sympatrically, hybridization probably takes
place, resulting in morphological intergradation. In
this area, many collections of subsp. rosei have
larger leaflets than normal in this entity, thus re-
sembling those of subsp. formosa. Such areas of
intergradation are in Tecpan de Galeana (e.g., Hin-
ton 14335, 10894, Ladd et al. 206) and Zihuata-
398, Ladd et al. 216,
Sousa 6159). Similarly, in some localities of the
nejo (e.g., Tenorio et al.
District of Yautepec in Oaxaca, plants from the
two subspecies have been found growing together
215, 217; Telles
13). The collections belonging
—
e.g., H. eie & Torres
Magallanes 111,
either to Z. formosa subsp. formosa or to subsp.
rosei, but of ambiguous identity, are listed sepa-
rately under Z. formosa subsp. formosa.
Zapoteca formosa subsp. formosa is distinguish-
able from the West Indian subsp. gracilis by hav-
ing oblong-obovate leaflets, usually larger, lanceo-
late to ovate-lanceolate stipules, and glabrous,
pubescent, or villous leaflets, which contrast with
the consistently glabrous ones of subsp. gracilis.
Subspecies formosa differs from subsp. mollicula
and subsp. schottii by its more robust habit, white
filaments, and larger Pers leaflets, stipules, flower

from northern Colombia and Venezuela to Bolivia,
southeastern Brazil and Paraguay (Fig. 44). Mor-
phologically, the populations from the southern
region clearly belong to the subspecies. Perhaps
this geographical fragmentation is related to the
current scarcity of relatively dry, seasonal, lowland
habitats in the intervening region. As reviewed by
Haffer (1982,

effect in tropical areas. In lowland areas of the
Neotropics, alternating periods of cooler and drier
climates probably caused extinction or displace-
ment of species adapted to the warm-wet forest
conditions during the interglacial periods, and only
a few areas (forest refugia) remain relatively un-
changed. Consequently, great expanses of wet for-
ests were replaced by drier, more open vegetation
in the Amazon Basin (Ab? 1982; Absy, 1982;
Bigarella & Andrade-Lima, 1982; van der Ham-
men. 19 1982; and others). In light
of this body of ideas, it can be postulated that the
populations of Z. formosa subsp. formosa found a
more suitable environment during the dry phases
of the and then were continuously
distributed across the Amazon Basin; and that the

Zapoteca formosa subsp. salvadorensis is closely
related to subsp. formosa, from which it can be
distinguished by having pilose or densely pilose pods
and by being villous on all vegetative parts. By
contrast, presence or absence of vestiture in subsp.
formosa is expressed irregularly throughout its
range. Geographically, these two subspecies are
allopatric.

Zapoteca formosa subsp. gracilis is relatively
uniform morphologically compared with the other
subspecies of Z. formosa. It is related to subsp.
formosa, from which it is distinguished by having
elliptic to elliptic-oblong leaflets and narrowly tri-
angular stipules and by being glabrous (Table 14).
The seeds of subsp. gracilis differ from those of
the remaining subspecies of Z. formosa by having
semiregular, instead of irregular, pleurograms.
Subspecies gracilis and subsp. formosa are essen-
tially allopatric, although there are a few collections
Cuba. Their rela-
of both from Oriente Province,
tionship is discussed further under Z. formosa subsp.
formosa.
Although leaflet morphology is quite constant
among populations of Z. formosa "E gracilis,
a few plants from the Bahamas (e.g., Correll &
Correll 45614, Curtis 82, Gillis 11 oe Hill 3003)
have unusually narrow leaflets. These plants could
be confused with Z. portoricensis but can be readi-
ly distinguished by their smaller and narrower stip-
ules and relatively thicker leaflets (also see Table
14). In addition, Z. formosa and Z. portoricensis
are strongly segregated geographically in the West

Distribution (Fig. 41). This subspecies occurs
along the Pacific slope of Mexico, from northern
Sonora south and southeast to the Isthmus of Te-
huantepec. It has also been collected in southern
Baja California and on the Revillagigedo Islands
(Isla Socorro and Isla Clarión). A number of col-
lections have been made from the districts of Yau-
tepec and Tlacolula. Oaxaca. and from a number
of localities in the Balsas Basin. It is relatively
common in disturbed or undisturbed habitats of
tropical thorn woodlands and tropical deciduous or
tropical semievergreen forests. It is found on steep
calcareous slopes, on volcanic rock, or along the
margins of seasonal streams at 01,430 m.

This polymorphic, highly variable subspecies,
along with Z. formosa subsp. formosa, represents
the phylogenetic core within the species. Leaflet
size is highly variable within and between popula-
tions, and a clinal variation pattern is evident,
especially in the northern portion of its range,
possibly a reflection of decreasing precipitation from
south to north. There is some variation in filament
color within Z. formosa subsp. rosei, although this
character is consistent at the populational level.
The distribution of the different color morphs is
not known with precision. The following generali-
zations can, however, be drawn: the most wide-
spread pattern of filament color is the white/red-
purple pattern, which occurs from southern Oaxaca
to Sonora and Chihuahua. The populations from
the Isthmus of Tehuantepec, at the eastern distri-
butional limit (e.g.. Hernández & Ramírez
918, Sousa & Téllez 8687), and a few populations
from Michoacán (e.g., H. Hernández & Chacón
185, Soto 1636)
ments. Populations from the districts of Tlacolula
have entirely red-purple fila-
and Yautepec, Oaxaca, have white pos filaments
(e.g.. H. Hernández & Ramírez 930, 943).
Zapoteca formosa subsp. rosei is closely related
to subsp. formosa and to subsp. mollicula and
subsp. schottii. It can be distinguished from subsp.
color of its filaments and by its
usually smaller leaflets. However, plants of these
two subspecies sometimes resemble each other
closely. In some localities of Guerrero, the two
subspecies become sympatric and apparently in-
tergrade morphologically. These collections are not
assigned to a particular subspecies; they have been
listed separately under subsp. formosa (and see
discussion under this subspecies).
will be discussed below under the respective
subspecies, patterns of morphological variation, es-
pecially in leaflet size, are essentially continuous
between Z. formosa subsp. rosei on the one hand
and subsp. mollicula and subsp. schottii on the
other. Although each of these is relatively easily
identifiable, their integrity breaks down because of
the existence of morphological intermediates. Za-
poteca formosa subsp. rosei can be distinguished
from subsp. mollicula by having more-developed
leaf parts (e.g., longer petioles and rachillae, usu-
ally more numerous and larger leaflets, and usually
larger stipules (Table
can be distinguished from subsp. schottii primarily
14)). Similarly, subsp. rosei

by having more numerous and larger leaflets (Table
14). Nevertheless, the differences between these
two subspecies are less marked than those sepa-
rating subsp. rosei and subsp. mollicula. Geo-
graphically, subsp. mollicula and subsp. schottii
are peripheral to but contiguous with subsp. roset.
This fact, along with their close morphological af-
finities, suggests that subsp. mollicula and subsp.
schottii were derived from subsp. roset. Further
discussion of the presumed relationships of these
three taxa is provided under the respective sub-
species.

Zapoteca formosa subsp. mollicula represents
an extreme of morphological variation within the
species in petiole length, number of pairs of pinnae,
and number and size of leaflets. It is distinguished
from the other subspecies by its |
pinnae with fewer and smaller leaflets and by its
aflet size, however
-, rarely 2-jugate
somewhat shorter internodes. Lea
is extremely variable in this sna o both at an
intra- and interpopulational level (e.g., Cruz Cis-
neros 2563, H. Hernández & Torres 216, Rose
& Hough 4671, Sousa et al. 6901, 0905). Sim-
ilarly, vestiture is highly variable, and does not
display any coherent pattern.
Zapoteca formosa subsp. mollicula clearly is
closely related to the highly variable subsp. rosei.
Perhaps the most taxonomically meaningful char-
acters separating these taxa are the usually more
reduced leaves of subsp. mollicula. However, vari-
ation in leaf characters (e.g., petiole length, number
of pinnae, number of leaflets, size of leaflets) is
essentially continuous, especially when plants of

Zapoteca formosa subsp. schottii is closely re-
lated to and was probably derived from subsp. rosei.
The former has generally smaller stature, less nu-
merous, smaller leaflets, and smaller pods (Table
These two taxa show geographically contig-
uous distributions (Fig. 44), and there is clinal
variation in leaflet size, with subsp. schottii oc-
Although the pat-
terns of morphological variation are apparently
cupying the extreme position.
continuous between the two taxa, subsp. schottii
is relatively easily recognizable as a separate taxo-
nomic unit with a somewhat arbitrary boundary.
In the Baboquivari Mountains and in northern So-
nora and Chihuahua, a number of difficultly placed
intermediate specimens have been collected.
Zapoteca formosa subsp. schottii could be con-
fused with subsp. mollicula, since they have leaflets
of comparable size. However, subsp. schottii can
be readily distinguished by the longer internodes
and more elongate petioles and rachillae (Table
4). Further, although vestiture is highly variable
in subsp. mollicula, most of its individuals have
denser vestiture than do plants of subsp. schottii.

This morphologically uniform species is closely
related to Z. formosa but differs by having scu-
telliform extrafloral glands, scandent habit, and
usually smaller, linear-triangular stipules. More-
over, it can be distinguished from Z. formosa subsp.
formosa by its white/pink, rather than white, fil-
aments. The scutelliform glands, which are con-
stant throughout the known populations of Z. scu-
tellifera, are an excellent diagnostic feature, as
they occur only in this species of Zapoteca. They
are fully developed at the earliest stages of leaf
development, which probably reflects their defen-
sive function.

Zapoteca tehuana is a narrowly endemic species
probably not closely related to species of subg.
Zapoteca, and further knowledge on this species
could provide evidence for its placement in a sep-
arate subgenus. It differs from the remaining species
of subg. Zapoteca primarily by having conspicuous
brochidodromous leaflet venation and relatively
thick leaflets. It might be confused with some of
the species with oblong or ovate-lanceolate leaflets
of comparable size (e.g.. Z. portoricensis and Z.
lambertiana) but differs by having leaves usually
having fewer pairs of pinnae, smaller stipules, white
or white/pink filaments, and shorter stature. The
relationship between Z. tehuana and Z. aculeata
are discussed under the latter.

Zapoteca aculeata represents by itself a sub-
genus of Zaboteca. It is a poorly known, unmis-
takable species characterized by spinescent sti-
pules, medium size, and coriaceous, ovate-lanceolate
leaflets, which are usually larger than the essen-
tially membranous leaflets of subg. Zapoteca. It is
not obviously closely related to any other species
of the genus; however, as shown in the chapter on
morphology, an analysis of its leaflet architecture
revealed outstanding similarities to that of Z.
huana. Zapoteca aculeata is known from only a
few collections made in a restricted area of the
Ecuadorian Andes and from cultivated individuals

This narrowly endemic species is clearly allied
to Z. amazonica, from which it is geographically
isolated (Fig. 47). Zapoteca microcephala can be
readily distinguished from that species by 1!2 pairs
of smaller leaflets per pinna, simple (nonramified),
shorter pseudopanicles, smaller stipules, and white
filaments. Table 15 provides an account of the
main comparative characters distinguishing these
closely related species. Zapoteca microcephala is
known from only four collections, 2 has not been
collected since Haught (1711, 1734) found it in
1935 in the floristically rich area of the Magdalena
River Valley, Colombia.

Zapoteca amazonica and Z. microcephala rep-
resent a distinct evolutionary line within the genus;
these closely related species probably differentiated
from a common ancestor after becoming separated
from the rest of the genus. Zapoteca amazonica,
which is remarkably uniform morphologically, can
be readily distinguished from Z. microcephala by
its scandent habit, one pair of larger leaflets per
pinna, larger stipules, elongate pseudopanicles, and
The
tween the two species were discussed further under
white/purple-red filaments. differences be-
Z. microcephala (see also Table 15).
Zapoteca amazonica probably is the most spe-
cialized species in the genus, presenting a combi-
nation of derived characters: scandent habit; ex-
treme reduction of leaflet number concomitant with
an increase in size; relatively complex leaflet ve-
nation patterns; capitula organized in complex, ter-
minal, compound pseudopanicles. The specialized
nature of this species was discussed in the section
on morphology.

which Helonias, Heloniopsis, and Ypsilandra represent one group, and ina and Chancetaphis another
distinct group
The Melanthiaceae comprise ca. 24 genera dis-
tributed in North America, Japan, and China (Dahl-
gren & Clifford, 1982). These genera are Aletris,
Amianthium, Chamaelirium, Chionographis, He-
Metanarthecium, Narthe-
Pleea,
Ste-
Toxicoscor-
lonias. Helontopsts.
Nietneria, Oceanoros, Petrosavia,
Schoenocaulon (= Sabadilla),
Tofieldia,
) psilandra, Ae-
cium,
Protolirion,
nanthella, Stenanthium,
dion, Tracvanthus, Veratrum,
rophyllum, and Zigadenus (Dahlgren & Clifford,
1982). Krause (1930) recognized the tribe To-
fieldieae (Liliaceae- Melanthioideae), in which To-
fieldia (Temperate-Arctic Northern Hemisphere),
Pleea (eastern North America), Varthecium
—
and
—
n
(Northern Hemisphere Vietneria (Guinea
were included. However. in his treatment, Aletris
was placed in the different subfamily, Alectroideae.
Hutchinson (1934, 1959) grouped these genera
into two tribes, Heloniadeae and Narthecieae. The
Heloniadeae, characterized by the absence of bracts,
consist of Helonias. Chamaelirium, Y psilandra,
and Chionographis. and the tribe Narthecieae,
characterized by the presence of bracts, comprise
Pleea, Tofieldia, Xerophyllum, He-
loniopsis. Clara, Metanarthecium,
Hewardia,
Varthecium,
Aletris, and Vietneria. Hutchinson (1934,
1959)
regarded the Heloniadeae as the most primitive
tribe in the Liliaceae, and that the tribe is closely
related to the Narthecieae. Dahlgren et al. (1985)
placed these genera in the family Melanthiaceae
Melan-
Chionographi-
and recognized six tribes, Petrosavieae,
thieae, Narthecieae, Tofieldieae,
deae, and Xerophylleae.
in the tribe Narthecieae.
Although many brief notes on pollen morphology
of these genera using light microscopy have been
given by Beug (1961). Erdtman (1952), Faegri et
al. (1964), Huang (1970, 1972), Huynh (1976),
(1956), Kuprianova (1948), Radurescu
1973), Schultze (1978), Shimakura (1973),
Thanikaimoni (1970), Ting-Su (1949), Utech
979), Wunderlich (1936), and Van der Hammen
(1956), a comprehensive pollen morphological study
has not been made for these genera with electron

ahashi (19822) showed that Heloniopsis orientalis
Tanaka is characterized by a peculiar exine struc-
ture without columellae. He also pointed out that
palynological evidence on the related genera would
be useful to reveal their systematic relationships.
In the present study, pollen grains of 92 samples
of 40 species of 15 genera in the Melanthiaceae
were studied in detail with transmission and scan-
ning electron microscopes. The probable system-
atic relationships of these genera are proposed based
on the palynological evidence thus obtained.
MATERIALS AND METHODS
Pollen grains were taken from specimens in the
herbaria of Carnegie Museum of Natural History
(CM), U.S. National Arboretum (NA), Kunming
Institute of Botany (KUN), Kyoto University
(KYO), and Tohoku University (TUS). Voucher
specimens are listed in Table 1. Pollen grains from
each specimen were observed using scanning elec-
tron and transmission electron microscopy. Prep-
aration methods followed Takahashi (1982b). An
image analyzing system IBAS-1 was used for mea-
surements and calculations of pollen grains.

DISCUSSION
Helonias and Ypsilandra are characterized by
a distinctive exine structure that consists of an

amorphous layer and spinules, and the same exine
structures were observed in Heloniopsis (Vaka-
hashi, 1982a). Utech (1978, 1980) and Utech &
Kawano (1981) suggested that //eloniopsis and
Helonias should be maintained in the same tribe
based on floral vasculature and karyology despite
Hutchinson's (1934, 1959) placement of /7elonias
in Heloniadeae apart from Heloniopsis in the Nar-
thecieae. The present pollen morphological evi-
dence supports the suggestion by Utech & Kawano
(1981) and further indicates that ) psilandra should
be included in the same tribe with /7elonias and
Heloniopsis. The three genera are closely related
to each other and are distinctive because of the
amorphous exine structure with spinules. Dahlgren
et al. (1985) included /lelonias and Heloniopsis
in the tribe Narthecieae, with Methanarthecium,
Vietneria, Narthecium, and Lophiola. We now
regard Helonias, Heloniopsis, and Y psilandra as
congeneric, and a more thorough taxonomic ac-
count of this controversial group is needed.
Chionographis from Japan has clavate exine
sculpture and four-porate pollen grains. Chamae-
lirium from the eastern United States has the same
pollen. This type of grain and exine structure are
unique in the Melanthiaceae, and suggest that Cha-
maelirium and Chionographis are closely related
to each other as an isolated group in the Melan-
thiaceae. The pollen morphology supports the
treatment of Dahlgren et al. (1985), who distin-
guished the tribe Chionographideae as made up of
Chionographis and Chamaelirium.
Japonolirion, which consists of only the Jap-
anese endemic J. ozense, is sometimes included in
Tofieldia (Willis, 1966; Hutchinson, 1934, 1959).
The pollen grains of Japonolirion are monosulcate
with gemmate exines, as opposed to those of 7o-
fieldia, which are disulcate with reticulate exines.
The pollen morphology of Japonolirion implies
that the genus should not be e in Tofieldia
but should be treated as a se e genus. The
report of gemmate exine of Tofieldia puo (Ikuse,
1956) appears to be incorrect, as we have found
reticulate exine in this species, conforming to other
para
species of Tofieldia.
There is a wide range of variation in exine sculp-
ture, perforate-foveolate, reticulate, and gemmate
types in the genus dletris. The species with gem-
mate exine are 4. lanuginosa and A. pauciflora,
which are distributed in China and Nepal. The other
species of Aletris have reticulate exines. Similar
variation in exine sculpture occurs in Clintonia
(Takahashi & Sohma, 1982) and Paris (Taka-
hashi, 1984). A parallel derivation from tectate-
perforate to intectate exine appears to have taken
place independently within these genera (laka-
hashi, 1984)
Ambrose (1985) transferred the genus Lophiola
into the Narthecieae. The exine sculpture of the
genus has a reticulum similar to that of genera in
the Narthecieae; thus the palynological evidence
supports Ambrose's taxonomic position of Lophiola.
| the evidence available at present suggests that
Heloniadeae and Narthecieae sensu Hutchinson
(1959) consist of at least three or four heterogenous
groups, and therefore the revision of the classifi-
catory system of these groups is now in order.

This beautiful, large-flowered species is placed
in subg. Plectostemma sect. Decaloba (Killip,
1938), where it resembles members of the Pas-
siflora alnifolia complex in leaf shape and form
of the outer coronal filaments. It is easily distin-
guished from those species by the large flowers and
fruits and by the incrassate reticulum formed by
expansion of the fine veins of the lower leaf surface.

The presence of petiolar nectaries and. purple
flowers with a nonplicate operculum, suggests a
relationship to P. lancifolia Desv., of subg. Chlo-
ropathanthus (Harms, 1925; Killip, 1938), which
is known only from Jamaica. Unlike that species
and others of subg. Chloropathanthus, P. sierrae
has well-developed petals, poorly developed lami-
nar foliar nectaries, and seeds with transverse ru-
gulose ridges. This unique combination of char-
acters requires the creation of a new subgenus.
Data from pollen studies (Prėsting, 1905; Spirlet,
1965; Escobar, unpubl.) suggest that several pur-
ple- or red-flowered species (usually with a tubular
hypanthium and therefore presumably humming-
bird-pollinated) have arisen independently from the
large and variable subg. Plectostemma. They do
not suggest that all species with the hummingbird-
pollinated syndrome are monophyletic.

3-6 mm wide, delicately membranaceous, greenish
white; corona in 2 series, the outer series linear,
7-8 mm long, ca. 1 mm wide, the inner filaments
ca. 3 mm long, 0.2 mm wide, operculum dependent
then recurved, loosely plicatez ovary globose, pu-
bescent. Fruits unknown.
Distribution. Passiflora solomonii is known
only from the type locality in La Paz Department
of Bolivia at 2,400 m elevation.
The unusual leaf shape of Passiflora solomonii
is reminiscent of P. exoperculata of subg. Plec-
tostemma but is transversely linear rather than
transversely ovate; P. exoperculata also differs
rom P. solomonii in possessing prominent petiolar
nectaries and capitellate inner coronal filaments as
well as longer peduncles and shorter leaf lobes.

GROUP 7. THE TEVUIFOLLA GROUP
Shrub or small tree; young stems glabrous or
puberulent; stipules often sheathing, ovate to tri-
angular with apex long-biacuminate in P. tenuifolia
(Fig. Ze), uniform in color, glabrous or puberulent,
caducous. Leaf blades elliptic (to sometimes slightly
ovate in P. limonensis), drying green-brown or
red-brown; secondary veins 8-21(-24) pairs, di-
verging (60°) 70?-90?(—95?),
mous with collector vein near margin, the axils
brochidodro-
lacking domatia or hairs; tertiary veins orthogonal
reticulate (to sometimes percurrent in P. limonen-
sis). Inflorescences umbelliform panicles of cymes
(Fig. 7f), the peduncle lacking or no more than 2
em long; secondary axes in one pair per rank;
bracts not conspicuously enlarged. Corolla tubes
1.5-2 mm long, the lobes without apical exten-
sions. Fruit when dry ellipsoid; persistent calyx
inconspicuous or a beak; seed dorsal surface with
-5 longitudinal furrows (often irregular in P. li-
monensis), the ventral surface with 2 longitudinal
furrows (often incompletely divided in P. limonen-
sis).
The two species in the group, Psychotria li-
monensis and P. tenuifolia, are both widespread

Psychotria limonensis may be recognized by
its broad-elliptic, thin-membranous leaves, brochi-
dodromous secondary veins with collector vein near
margin, broad umbelliform inflorescences, and small
—
usually 4 mm long) ellipsoid to subspherical fruit.
Leaves on Mexican and Guatemalan specimens
have fewer secondary veins than those from else-
where; the secondaries diverge characteristically
at acute (vs. right) angles in Nicaragua.

This variable species includes P. sessilifolia
(Mexico;
ragua; broad leaves). and P. sulzneri (Florida; small,
narrow leaves). P. granadensis (Nica-
narrow leaves).
Psychotria tenuifolia may be recognized by its
narrow-elliptic, thin-membranous leaves; brochi-
dodromous secondary veins with collector vein near
the margin; small umbelliform panicles of cymes:
and small (4-5 mm long) ellipsoid fruits. Specimens
from Honduras and further north are more pu-
berulent, especially on the leaf underside,
inflores-
from Nicaragua and south. Honduran
cences have especially conspicuous linear bracts.

P. chitariana, P. dressleri; Fig. 7d), delicate only
in P. rosulatifolia; bracts often conspicuous. Co-
rolla tubes (1.5-)2-5 mm long (10-12 mm in P.
dressleri), the lobes usually with apical exten-
sions, protuberances, or thickenings. Fruit when
dry ellipsoid; persistent calyx inconspicuous or

rows, the ventral surface with 2 shallow, often
incompletely divided longitudinal furrows.

Only Psychotria calophylla (Fig.
only the former has been collected north of Nica-
ragua. Psychotria rosulatifolia and P. dressleri
occur in eastern Panama (Figs. 35, 36) and share
inflorescence secondary axes often in size-differ-
entiated pairs, and therefore may be closely related;
but phylogenetic relationships among these mostly
narrowly endemic species are difficult to hypoth-
esize.
Of the twelve species in the group, four are
normally distylous; only one of those — Psychotria
Inflorescences panicles of cymes or of
try in floral part length. Psychotria rosulatifolia
appears pin-monomorphic, based on five flowering
collections examined. Psychotria monteverdensis
appears long-homostylous. The remaining six species
are represented by few or no flowering collections
and cannot be assessed.

The three species named from central Pana-
gatunensis,
ma— Psychotria cerroazulensis, P.
and P. have morphologies
within the range of P. calophylla and are therefore
included. One of the three specimens at MO of
grandicarpa well
Dwyer et al. 7244, cited as the type of P. gran-
dicarpa, is hereby chosen as the lectotype.
Psychotria calophylla may be rec ib by
its arborescent habit, large (usually 1: x
12 em), elliptic to obovate leaves
red-brown tomentose below), undulate collector vein,
iss uso
large panicles of glomerules with secondary axes
usually in 3 ranks, and large (10-14 x 6-9 mm)
ellipsoid fruits. Collections from Guatemala are
noteworthy in that the leaf blades are obovate, as
opposed to the more comon elliptic shape. and have
ewer secondary veins than elsewhere in the range
of the species.

Psychotria monteverdensis may be recognized
by its subcoriaceous medium-sized (usually 13-15
x 3-4.5 em) leaves with collector vein, small (3.6
cm long) inflorescences with secondary axes 2 per
rank in 2 ranks, those of the second rank sessile,
and leathery greenish corollas with keel-like abaxial
appendages on the lobes.
Inly one flower was dissected, but the minute
separation (0.3 mm) between stigma and anthers
suggests that the species is long-homostylous.

This species is closely related to Anthurium
guanchezii Bunting but differs by having a car-
tilaginous leaf blade not basally stipitate, the low-
ermost primary lateral veins not naked in the basal
sinus, a proportionally narrower spathe, and a non-
stipitate spadix. In 4. guanchezii Bunting, the
or semicoriaceous, and the
blade is pergamen
spathe is 3.6 times longer than broad. Additionally,
A. iramirezae grows at an altitude of 1,350 m on
granitic outerops with thin soil and woody vege-
tation to 10 m tall, whereas 4. guanchezu occurs
in moist forests at 120 m altitude some 500 km
to the north.
rom 4. wurdackii Bunting, the new species
differs by having leaf blades that tend to be ovate
and proportionally broader with an arcuate basal
sinus, while the peduncle is shorter and the base
of the spathe is more shortly decurrent. In A.
wurdackii, the leaf blade is often elliptic-ovate,
about 1.9 times longer than wide with an angular
basal sinus, and the spathe is decurrent for 3.5-
7.5 cm. Further. the leaf blade of 4.
apparently lacks abaxial, dark punctations such as
wurdackii
occur in A. iramirezae.
The species is named in honor of a collector of
the type material. Ivón Ramirez, a young Vene-
zue

an botanist who also successfully introduced it

alibus primariis utrinque 9-11 sub angulo 55-65? ex costa

Subrosulate, perennial herb. Stem short, stout,
with accumulated, rust-colored, fibrous cataphyll
remains. Petioles abaxially rounded, with adaxial
face broadly but shallowly concave, to 19 cm long.
Leaf blades subcoriaceous, oblong, to 58 cm long
(3 times longer than petioles), 16.5 cm wide (ca.
3.5 times longer than wide), at base rounded and
notched (1 em deep), at apex acute or obtuse and
briefly acuminate; primary lateral veins 9-11 aris-
ing from each side of midrib at angles of 55-65*,
with some secondary lateral veins manifest. Inflo-
rescence unknown.
The type collection was taken from a plant grow-
ing as an epiphyte 2 m above the ground; it is not
certain that it represents the fully mature adult
phase of this species. A similar though somewhat
less adult plant, collected in the same area as the
type, has recently been seen in cultivation at the
family home of Lic. Germàn Carnevali in Maracay,
Venezuela. A juvenile specimen, Bunting 2916
(MY), collected in the same sector at km 126 south
of El Dorado, Bolivar, Venezuela, apparently per-
tains to this taxon. It has leaves of similar form,
texture, and color, but, as is typical of juvenile
shoots, has a more slender stem with elongate in-
ternodes and has wide-winged petioles basally en-
circling the stem and sheathed up to the base of
the blade.
This species differs from Philodendron meli-
nonii Brongn. ex Regel by the proportionally short-
er petioles and narrower leaf blades. In P. meli-
nonii, the blade length is 1.4 times longer than
the petiole and 1.5- 2.4 times longer than wide.
The specific epithet reflects the fact that the
leaf blade is three times longer than the petiole
and more than three times longer than wide.
I am grateful to Lic. German Carnevali and his
wife, Sra. Ivón Ramirez de Carnevali, for making
available dried and living specimens of the aroids
collected by them during recent botanical explo-
rations. My appreciation is expressed to the Di-
rector and personnel of the Herbario Nacional
EN), Jardin Botánico, Caracas, for the loan of
herbarium material.

HOSTA JONESII
(LILIACEAE/FUNKIACEAE),
A NEW SPECIES
FROM KOREA
Hosta Tratt. is an economically important genus
of approximately 22-25 species restricted to east-
ern Asia. Hosta has been placed in the Liliaceae
1981; 1964) or Funki-
aceae (Dahlgren et al., 1985). Bailey (1930), Stearn
(1931), and Hylander (1954) all pointed out that
the major difficulty with the classification of the
(Cronquist, Hutchinson,
Hosta lies in the uncertainty regarding criteria for
delimiting the species. The taxonomic difficulties
have been attributed to relatively few diagnostic
characters (Fujita, 1976), the extreme difference
in appearance between living plants and dried her-
barium specimens (Hylander, 1954), and possible
widespread hybridization (Maekawa, 1940). Thus
the treatment of species within Hosta has varied
Maekawa
1969) described several new species but combined
depending on authors. For example,
others recognized in his 1940 treatment. Fujita
(1976) noted that Maekawa (1940, 1969) did not
consider the variability of natural populations when
developing his classification. Fujita recognized only
15 species as native to Japan, while Maekawa
(1969) had recognized 25 species there. Although
Fujita carefully described morphological characters
and ecological and geographical distribution, his
studies were confined to Japan.
In 1985, 1987, and 1988,
trips to collect hostas from natural populations in
| conducted field
Korea and on Tsushima Island of Japan in order
to understand better the variation patterns. While
visiting several islands off the coast of southern
Korea, | encountered a morphologically distinct
group of Hosta DoD ie not referable to any
described species of Hosta. The herbaria at Seoul
National University (SNU), Tokyo University (TD,
and Kyoto University (K YO) were visited and there
were several undetermined specimens of this group
collected by Young Chung (SNU) and one specimen
collected by T. Nakai (TI). Loans were examined
from BH, BM, E. K, L,
specimens of the group were encountered.

Hosta jonesii is distinguished from other species
of Hosta by the navicular, green, persistent bracts;
thick, adaxially dark dull green leaves; and white-
lined leaf margins. This species appears to be re-
lated to H. minor (Baker) Nakai by the shape of
bracts and perianths and by the creeping rhizomes.
It differs by the terete scapes, elliptic-lanceolate
eaf blades, and flowering period from middle Au-
gust to early September. Hosta minor flowers in
mid July to early August and is endemic to south-
eastern Korea, including Wando and Kojae islands.
The new taxon also is very close to /7. tsushimensis

by having short creeping rhizomes; longer perianth
lobes; upper dilated portions of perianth tubes bell-

shaped; whitish purple inner perianth nerves; scapes
dotted basally with purple; thinly white-lined leaf

H. jonesii by having ovate, adaxially lustrous leaves;
delicate raceme of flowers spread around the cen-
tral axis of the inflorescence; decurrent, flat bracts;
relatively longer pedicels; and distinct, exserted
3+3 stamens.
The new species is named in honor of Dr. Samuel
B. Jones, who has provided encouragement with
my studies of Hosta. I thank Dr. Richard A. LaFleur
for correcting the Latin description and Nancy C.
Coile for comments on this manuscript. I also thank
Dr. N. Fujita, Dr. H. Obha, and Mr. Haynes Currie

Although this distinctive new species resembles
species of Mandevilla, it belongs to Allomarkgra-
fia, which differs from Mandevilla primarily in the
paniculately branched inflorescence. However, this
species is not at all close to 4. plumeriiflora Woods.,
with which it was first identified. Among the obvious
ANN. MISSOURI Bor. GARD.
features differentiating A. laxiflora from A. plu-
mertiflora are the very openly branched inflores-
cences with small bracts, very differently shaped,
narrower flowers, and narrower leaves.
dllomarkgrafia laxiflora is probably more
closely related to 4. foreroi ^. Gentry and 4. ovalis
(Mgf.) Woodson.
Colombia, and both of which have similar laxly
both of which occur in. Chocó,
branching inflorescences. The new species differs
vegetatively from both of these species in having
very obscure leaf venation like that of 4. plume-
riiflora. The distinctive corolla shape of 4. laxi-
flora likewise helps separate it from its two probable
closest relatives. In 4. ovalis the corolla is broadly
(vs. narrowly) infundibuliform-campanulate above

the basal tube, and in 4. foreroi it is more narrowly
campanulate above the basal tube, which is longer
and narrower than that of the new species. Allo-
markgrafia foreroi differs further from A. laxi-
flora in having slender, more tenuous inflorescence
branches; longer, thinner calyx lobes; and differ-
ently colored flowers (white with upper tube green-
ish and lower tube reddish).
There are only two other Allomarkgrafia species
in addition to those discussed above: Peruvian 4.
tubiflora Woodson ex Dwyer has leaves like 4.
ovalis and a longer campanulate upper corolla tube
much like that of many Bignoniaceae, while Costa
Rican 4. brenesiana Woods. has white flowers with
a gradually and narrowly infundibuliform upper
part of the corolla tube. Another Costa Rican species
described by Woodson is conspecific with 4. plu-
meriiflora.
Thus from a bitypic genus (Woodson, 1933)
Allomarkgrafia has now grown to six spec les. As
currently. known,

A. ovalis is wide-

CHROMOSOME NUMBER
IN WALLERIA
(TECOPHILAEACEAE)
The small African genus Jf alleria, comprising
three species (Carter, 1962), is generally consid-
ered to be allied to the Lilialean family Tecophi-
laeaceae. The five core genera of Tecophilaeaceae,
Tecophilaea, Zephyra, and Conanthera (all Chil-
ean), Odontostomum (Californian), and Cyanella
(southern African), are small seasonal perennials
united by their tunicate cormous rootstock, basally
clustered leaves, racemose inflorescences, and flow-
ers with poricidal anthers, partly inferior ovary,
and subulate style with a punctiform stigma. In
addition, the pollen grains have an operculate sul-
cus and tectate-columellate ektexine (Simpson,
1985), and the smooth seeds have a multilayered
testa with a black, phytomelan-encrusted outer lay-
er. As treated by Hutchinson (1934), the first mod-
ern phylogenist to recognize the family, Tecophi-
laeaceae also included the African. Cyanastrum,
now generally treated as the sole genus of Cy-
anastraceae (Dahlgren et al., 1985; Simpson,
1985). In 1959 Hutchinson transferred Walleria
to Tecophilaeaceae from Liliaceae- Dianelleae
(Hutchinson, 1934). Dahlgren et al. (1985: 165)
accepted Walleria in Tecophilaeaceae with res-
ervations; Dahlgren & van Wyk (1988) concluded
that it did belong in the family, although they placed
it in its own subfamily, Wallerioideae.
Walleria is discordant in Tecophilaeaceae for
several reasons. The rootstock is a fleshy naked
tuber, the leaves are cauline (not basal), the inflo-
rescence is foliose, and the ovary is completely
superior. Also, the seeds are warty and dark brown,
not smooth and black, and it is uncertain whether
they contain phytomelan (Dahlgren & van Wyk,
1988), although this is said to be absent by Huber
(1969). Simpson (1985) demonstrated that the pol-
len grains of Halleria resemble those of other
Tecophilaeaceae in having a medial apertural oper-
culate sulcus and an endexinous basal layer of the
operculum and aperture border. Although the oper-
culum of Walleria differs from other Tecophilae-
aceae in being very scanty and in having a granular
(vs. tectate-columellate) ektexine, its basic. struc-
tural similarity with that of the core genera of the
family supports inclusion of If alleria there (Simp-
1985). Embryologically, W'alleria differs in
son,
ANN.
having mostly campylotropous ovules (anatropous
in other Tecophilaeaceae) and a large embryo
(Dahlgren & van Wyk, 1988). With this back-
ground in mind, we undertook this investigation of
the chromosome number in the two tropical African
members of the genus, previously unknown cyto-
logically.
MATERIALS AND METHODS
Root tips were harvested at mid-morning from
greenhouse-grown wild-collected material, tubers
of W. mackenzii and seeds of IF. nutans. The tips
were placed in saturated aqueous mono-bromo-
naphthalene, and left at room temperature for four
hours before fixation in 3: 1 absolute ethanol- gla-
cial acetic acid for two minutes. After hydrolysis
in 10% HCl for six minutes at 600°C,
portions of the tips were squashed in FLP orcein
(Jackson, 1972).
Voucher data are as follows:

OBSERVATIONS AND DISCUSSION
The diploid chromosome number in both species
of Walleria examined is 2n = 24. The chromo-
somes are of moderate size, 2-4 um in the method
used. The chromosomes are mostly acrocentric but
four of the smaller pairs are sub- ete as
Basic chromosome number in Te
is probably = 12 rnduff, 197 9: Cink
0). C nets has predominantly n = 12 or 24
ca a population of C. hyacinthoides has n
14, and one Pp of C. lutea has n =
(Ornduff. 1979). the New World genera ex-
amined ae Tecophilaea has n = 12 (La
Cour, 1955) and Odontostomum n = 10 (Cave,
1949, 1970). The chromosome cytology of Wal-
leria thus accords well with Tecophilaeaceae and,
viewed in conjunction with data reviewed above,
supports its placement here.

At MO we still have very little material of this
genus from Venezuela, where a second species, D.
clusiifolia (Maguire) D’Arcy, is endemic (one col-
lection, Schultes 11755, is from Vaupés in south-
eastern Colombia). Although I can see no way to
distinguish sterile material of D. clusufolia from
D. paniculata, seemingly minor differences in the
staminate flowers, along the lines indicated by Ma-
guire (1977) and D'Arcy (1978), do hold up for
the many new collections of the latter species,
which is restricted to Colombia, Panama, and Costa
Rica. However, contrary to somewhat inaccurate
and contradictory interpretations of prior authors,
the flowers of both species have two bracteoles;
the internode between the bracteoles and sepals is
shorter in D. clusiifolia than in D. paniculata.
In addition to differences in the staminate flow-
ers, the fruits of D. clusiifolia appear to have
somewhat longer stigmas (or at least they persist
longer) and are slightly larger at maturity. than
those of D. paniculata.

Robson (1958) discussed the logical error in
maintaining Rheedia separate from Garcinia, es-
sentially saying that no basis for separating them
exists. Previously, Garcinia was not considered to
occur naturally in the New World, only Rheedia.
Features thought to distinguish Rheedia from Gar-
cinia (number of perianth parts and degree of
fusion of the stamens) are not constant in Rheedia
and occur in both genera. Adams (1972) and Four-

net (1978) treated Rheedia as a synonym of Gar-
D'Arcy
(1980) nevertheless kept the two genera separate
cinia for floras within the. West. [ndies.
on grounds that transferring the species of subg.
Rheediopsis from Garcinia to Rheedia would be
"more correct" than uniting Rheedia with Gar-
cinia. Recent comparative work within the family
supports Robson's position (P. Stevens, pers.
comm .).
Seemann's epithet (edule) cannot be transferred
to Garcinia as it would create a later homonym.
Rheedia intermedia clearly belongs in Garcinia
and provides the oldest available epithet for the
spec ies.
Garcinia intermedia is the only Central Amer-
ican member of the genus with a soft, edible, exo-
carp. All others have a thick, tough, inedible exo-
carp and delicious, white, acidic, sweet endocarp
(as in the mangosteen, Garcinia mangostana L.).
Leaf sizes and shapes are variable in the species
and encompass the narrow-leaved material named
as Rheedia tonduziana.

A NEW SPECIES OF
CALYCOLPUS (MYRTACEAE)
FROM THE VENEZUELAN
GUAYANA
In preparation of a treatment of the subtribe
Myrtinae (Myrtaceae) for the Flora of the Vene-
zuelan Guayana a new species of Calycolpus has
come to my attention. It is known to me through
two collections, both from Estado Bolivar, Vene-
zuela. It clearly belongs to Calycolpus as shown
by the following combination of characters: flowers
pentamerous and erect; stamens exserted, the an-
thers elongate, with several glands in the connec-
tive; seed coat lustrous with no pulpy covering, the
outer seed coat ca. | cell thick at narrowest point,
the superficial cells of the seed coat nearly isodi-
ametric.

(ZINGIBERALES)
Chromosome counts are available for most Afro-
Madagascan members of Strelitziaceae but until
now the neotropical Phenakospermum has been
unknown cytologically. Chromosome cytology of
the small southern African genus Strelitzia is com-
paratively well known. The two acaulescent species

been reported by Sató (1948, 1960) as having 2n

have diploid numbers of 25 —

Dyer, is unknown cytologically.
It has seemed puzzling that the chromosome
number of S. nicolai corresponded with the two
acaulescent species rather than with the allied cau-
lescent 5. alba, particularly as the merit of main-
taining the two species as separate (Geldenhuys,
pers. comm.) is in some doubt. We have now es-
tablished that at least one Transkeian population
of S. nicolai has the same chromosome number,

MATERIALS AND METHODS
Seeds collected in the wild were germinated in
the greenhouse. Actively growing root tips were
harvested at mid morning into saturated aqueous
mono-bromo-naphthalene and left at room tem-
perature for four hours before fixation in 3:1 ab-
solute ethanol-glacial acetic acid for two minutes.
After hydrolysis in 10% HCl for six minutes at
60°C, the apical portions of the tips were squashed

it reasonable to hypothesize that x = 11 is basic

Central Africa. Most are from Mozambique (Dyer

Zimbabwe (Dyer & Verdoorn, 1969), and, to a
lesser extent, Zaire (Devred, 1959; Malaisse, 1969).

For example, foliage characteristics are closest to
E. bubalinus and (especially) E. hildebrandtii in
that 1—5 spinose teeth are present on the basal
curve of the superior margin of the median pinnae,
and at least one spinose tooth is present near the
basal portion of the inferior margin. Encephalartos
voiensis differs from these two species by having
subfalcate, very abruptly cuneate basally, very dark
green to blue-green leaflets, and the transition to

the aforementioned species, but none that is com-

First, vegetative characters are always present and

often exhibit more obvious macroscopic diversity

data concerning reproductive characters are either
fragmentary or nonexistent, and herbarium ma-
terial is highly unreliable because of the vast amount
of distortion of size and shape induced by drying.
Thirdly, because all cycads are dioecious, we think
it is important to establish vegetative characters

In a shipment of Lauraceae recently received

strongly unequal tepals.

and staminodia attached. Outer tepals broadly ovate,
ca. 2 mm long, appressed-pubescent outside, gla-
brous inside. Inner tepals elliptic, ca. 6 mm long,
appressed-pubescent on both surfaces. Fertile sta-

as long as the outer stamens, the filament similarly
pubescent, the anther as wide as the filament and

(whorl IV) ca. 2.5 mm long, widened at base,
filament densely pubescent, inside of the anther

ca. 1 mm long. glabrous or with few hairs near the
apex; style ca. 2.5 mm long, glabrous. Fruit un-
known; tepals deciduous in very early fruiting stage.
The distinctive characters of P. julianae make
it difficult to place in the most recent infrageneric
classification. In her revision of the neotropical
species of Persea, Kopp (1966) recognized two
subgenera. Subgenus Persea is characterized by
its equal tepals that are pubescent on inner and
outer surfaces, usually puberulous ovary, and te-
pals deciduous at the fruiting stage. This subgenus
includes the type species of Persea, P. americana
Mill.,
Subgenus Eriodaphne is
and three other Central American species
characterized by its
strongly unequal tepals with the outer tepals in-
ternally glabrous, usually glabrous ovary, and per-
sistent tepals in the fruiting stage. This subgenus
includes about 70 neotropical species and is further
divided by Kopp (1966) into four sections. Section
Mutisaea includes the species with a corymbiform
inflorescence; section Hexanthera includes species
with only six fertile stamens (representing the out-
ermost whorls), section lurataea includes species
with a (sometimes slightly) pubescent ovary; and
section Eriodaphne includes the remaining species,
with a glabrous ovary. The species with partly or
entirely two-celled stamens belong to section £r-
iodaphne. Thus, the two subgenera can be readily
identified in flower (tepals equal vs. unequal) and
fruit (tepals deciduous vs. persistent).
e usefulness of this classification of the neo-
tropical Persea species is undercut by several species
with characters of both subgenera. Several Central
American species (for example P. albida Koster-
Allen, and P.
Werff) have equal tepals, which are persistent in
mans, P. rigens sylvatica van der

mans. As noted, the strongly unequal tepals, gla-
brous ovary, and number of fertile stamens sepa-
rate P. julianae from the cultivated P. americana.
Specimens treated by Kostermans (1936) as P.
benthamiana were included by Kopp (1966) under
P. nivea Mez and are characterized by having nine
fertile stamens, persistent tepals, and glaucous
whitish lower leaf surfaces.
Persea coriacea is an enigmatic species known
only from the type collection, from the Hendrik
Peak in the ma Chain, not far from the Juliana
Peak. This species is described as having subequal
tepals + 1.75 mm long and nine fertile stamens;
these details separate it clearly from P. julianae.
Kostermans (1936) also mentioned that the fruit
was subtended by a small, flat cupule with an entire
margin, a character not found in any other Persea
species. This was probably one reason why Ko
(1966) excluded P. coriacea from Persea without
suggesting an alternative generic placement. The
MO isotype of P. coriacea does not solve these
difficulties. The label states that flower buds and
fruits were collected. Presence of floral buds and
fruits on the same specimen is very unusual for
Lauraceae and is often the result of a disease in
which galls, developed from buds, are mistaken for
fruits. The buds on the MO isotype are diseased,
which explains Kostermans's observation that fre-
ently a staminode of the fifth whorl is present.
The papillose lower leaf surface is against its in-
clusion in Persea. Papillose lower leaf surfaces are
common but not restricted to Aniba, but P. co-
riacea does not match any Aniba species | know.
I regard P. coriacea as a name based on a mon-
strosity, different from the other Persea species
reported from Surinam; for correct placement, ad-
ditional specimens are needed.
I thank Dra. M. Werkhoven for making the
specimen available. J. Myers drew the illustration.

This recently published volume of the Flora of
Australia is the first of three that will cover that
arge group of trees and shrubs, the Myrtaceae. It
is beautifully illustrated with numerous line draw-
ings and seven pages of color photographs, is print-
ed on high-quality paper, and has a good paperback
binding. The volume includes a family description
by A. S. George and treatments by G. M. Chip-
pendale of the diverse genus Fucalyptus L Hér.
(513 species) and the much smaller Angophora
Cav. (7 species). George calculates that there are
about 75 genera and over 1,500 species of Myr-
taceae in Australia. Thus, Fucalyptus accounts for
about one third of the family there. As stated in

species of Fucalyptus are also planted around the
world for ornamental and forestry purposes. Chip-
pendale's contribution is very welcome indeed.
An informative introduction relates some of the
taxonomic history of Fucalyptus. The last com-
plete account was that of Blakely, 4 Key to the
Eucalvpts (1934), with updated editions appearing
in 1955 and 1965. Until the late 1950s taxonomy
was based on macroscopic characters of buds, fruits,
and anthers, but since then a variety of anatomical
and inflorescence features have been investigated
by various workers. Presently, studies of Kucalyp-
tus are appearing at an explosive rate. A quick
look at the 18 issues of the dustralian Journal of
Botany for the period 1984-1986 shows that not
one issue was without at least one article with
Eucalyptus in the title and that 59 articles on
Eucalyptus appeared, 18 of which were system-
atic. Thus, Chippendale's treatment is necessarily
a synthesis of knowledge of Fucalyptus as it was
in the mid 1980s, and it will soon be out-of-date.
In fact, 24 species published while the book was
being typeset could not be included. But consid-
ering the history of Fucalyptus, we cannot expect
another comprehensive work soon.
Chippendale briefly reviews some of the features
that have been used in systematic studies of Fu-
calyptus, viz., stamens and anthers, cotyledons,
operculum, ovules, leaf waxes, oil glands, tri-
chomes, and stigma and style morphology. How-
ever, his key to species depends on “readily-ob-
servable characters of habit, bark, leaf arrangement
and form, inflorescence, buds and fruit. ^
Near the beginning of the volume are color
photographs illustrating types of bark, habit, and
various species in flower. Labeling the photographs
of the various bark types would have made them
more useful.
There are 60 pages of keys for Eucalyptus,
first one dividing the species into 20 groups and
then a key to the species in each group. For sys-
tematic treatment the species are divided into 92
series, but these have no close relationship to the
20 groups of species in the key. A description of
each series is provided with an accompanying ci-
tation of type and notes on size, distribution, and
distinguishing characteristics. There is no key to
or synopsis of the series, but they are divided into
groups in the introduction of the genus under the
discussion of some of the systematically important
characters. For each species are provided: a de-
scription of ca. 8 lines; citation of types, synonyms,
and published illustrations; a figure illustrating buds
and fruits; a short list of representative specimens;
and notes on distribution and distinguishing char-
acteristics. Distribution maps for all species are
found on 38 pages at the end of the systematic
treatment.
he style of the keys is very brief. Usually only
one character comparison is made in each couplet
and the alternatives can sometimes seem rather

ABSTRACT
A preliminary checklist of the vascular plant flora of Cerro Aracamuni, an isolated sandstone massif of the Roraima
Shield in southern Territorio Federal Amazonas, Venezuela, is presented. The list is based on collections from five

made. The new ims include /lex aracamuniana (Aquifoliaceae); Philodendron roraimae subsp. aracamuniense
(Araceae); Pochota aracamuniana (Bombacaceae); Navia carnevalii, N. iosothrix, N. patria, N. platyphylla
terramarae (Bromeliaceae); Hexapterella steyermarkii (Burmanniaceae); Symbolanthus aracamuniensis cas
naceae); Licaria trinervis (Lauraceae); Tococa liesneri (Melastomata ceae); Sauvagesia guianensis subsp. araca-
muniensis (Ochnaceae); dices amunia liesneri (Orchidaceae); Piper mosaicum (Piperaceae); Rapatea aracamuniana
(Rapateaceae); Cephalodendron aracamuniensis, Coussarea liesneri, Neblinathamnus aracamunianus, Remijia
reducta (Rubiaceae); Bonnetia liesneri, Ternstroemia guanchezii, T. maguirei (Theaceae); Abolboda scabrida,
Xyris aracamunae, X. liesneri, and X. prolificans (Xyridaceae). The three new combinations are: Paepalanthus
sulcatus (Eriocaulaceae); Senefeldera yutajensis (Euphorbiaceae); and Persea perseiphylla (Lauraceae).

Avispa, and apparently from Cerro Aracamuni,
were made by Felix Cardona Puig and G.C.K.
& E. Dunsterville on a trip with the Venezuelan
Border Commission in 1972. Coordinates used by
them for what they called the ““Aracamuni section
of Cerro Avispa” (01*30'N, 65?*51'W) match very
closely with those from the most recent expedition
to Cerro Aracamuni. Charles Brewer Carias gath-
ered several plants during a stop to the summit by
helicopter in 1983. Small gatherings of plants from
the base and slopes of Aracamuni were made on
two other occasions, in 1959 from a 900-m-tall
granitic outlier of Cerro Aracamuni by John Wur-
dack and Lincoln Adderley, and from an eastern
escarpment of Aracamuni at 750 m by Otto Huber
and Ernesto Medina in 1981.
Cerro Aracamuni is the largest of the table
mountains closest to Cerro de la Neblina, so ex-
ploration of its summit was considered essential to
help verify that the high degree of endemism re-
ported from Neblina was not an artifact of incom-
plete collecting. Although the summit of Cerro Ara-
camuni attains an elevation of only 1,500 m, con-
trasted with. 3,040 m on Neblina, most of the
summit of Neblina lies between 1,800 and 2,200 m.
In 1987, the Terramar Foundation of Venezuela
provided Ronald Liesner of the Missouri Botanical
Garden and Germán Carnevali and Francisco De-
lascio of the Herbario Nacional de Venezuela the
opportunity to explore the summit and slopes of
Cerro Aracamuni between October 15 and No-
vember 3, 1987. They gathered a total of 1,018
collections (including some bryophytes and fungi,
which are not considered in this paper) from the
summit and slopes.
Cerro Aracamuni lies near the southern tip of
Territorio Federal Amazonas, Venezuela, in Dept
Rio Negro, approximately 125-140 km northeast
of Cerro de la Neblina (Fig. 1). It is a small to
medium-sized massif for the Guayana region, rath-
er long and narrow with a north-to-south orienta-
tion, extending from 01?24'N, 65°47'W to
01°32'N, 65?49'W. Vertical sandstone escarp-
ments flank some of the sides, and a few rock
outcrops appear on the upper edges. From its sum-
mit, streams drain into the Matapire and Siapa
rivers on the east, north, and south, and into the
Rio Yatúa on the west. Several kilometers of low-
land rainforest extend on the Rio Siapa side to the
base of the massif. The large rapids, Raudal and
Salto Gallineta, are prominent topographic features
on the igneous outcrops along the Rio Siapa. Most
of the massif is believed to be of Roraima sandstone.
A close relationship with the flora of Cerro de
la Neblina is expected on Cerro Aracamuni due to
the proximity of the two massifs. Four of the genera
previously known only from Cerro de la Neblina,
Neblinanthera, Celiantha, Cephalodendron, and
Neblinathamnus, are now known from Cerro Ara-
camuni as well. Species (and subspecies) previously
known only from Neblina, and now recorded from
Aracamuni, are: Sobralia speciosa C. Schweinf.,
Endlicheria vinotincta Allen, Spathelia nebli-
naensis R. Cowan & Briz., Diacidia glaucifolia
(Maguire) W. R. Anderson, Philacra auriculata
Dwyer, Tyleria silvana Maguire, Maieta nebli-
nensis Wurd., Neblinanthera cumbrensis Wurd.,
Tococa pachystachya Wurd., Orthaea wurdackii
Maguire, Steyerm. & Luteyn, Celiantha bella Ma-
guire & Steyerm., Faramea boomii Steyerm., Fer-
dinandusa neblinensis Steyerm., and Pagameop-
sis maguirei subsp. neblinensis Steyerm.
Two additions to the Venezuelan flora from the
Aracamuni expeditions are Tyleria silvana Ma-
guire, previously known from the Brazilian side of
Cerro de la Neblina and Serra Pirapucü, and an
as of yet unidentified species of the genus Jacques-
huberia, previously known only from Amazonian
Brazil and Colombia.
VEGETATION OF THE SUMMIT
The summit is covered mostly by 0.5—1-m-high,
dense savanna (non-Poaceae) and low shrub vege-
tation, and small forested areas occur in depres-
sions and along streams. The savanna is inhabited
mostly by Eriocaulaceae, Rapateaceae, Bromeli-
aceae, Xyridaceae, Liliaceae, and Sarraceniaceae.
Common shrubs and small trees of the savanna
include Poecilandra retusa, Pagameopsis ma-
guirei subsp. neblinensis, Bonnetia tristyla, Di-
stictella monophylla, Emmotum glabrum, and
Gongylolepis huachamacari. The patches of for-
est and gallery forest include Neblinanthera cum-
brensis, Aegiphila roraimensis, Clusia sp., Dia-
cidia glaucifolia, Phyllanthus vaccintifolius,
Psychotria duricoria, P. tapajozensis, and Ty-
leria silvana.
The remainder of this paper is divided into two
sections, descriptions of new taxa and presentation
of new combinations, and the preliminary checklist
of the flora of Cerro Aracamuni.

The characters that separate the two subspecies
of P. roraimae are few, yet the specimens seem
quite distinct at first glance, chiefly because of the
proportionally narrower leaf blade of subsp. ara-
camuniense. Even the juvenile leaves of both taxa
have a similar, narrow blade outline. An important
difference may prove to be petiole shape, said to
be terete in the Aracamuni collections; in the ma-

This is the common Philodendron growing on
the summit of Cerro Aracamuni, climbing up tree
trunks. Its relation to P. nebulense Bunting (de-
scribed from Cerro de la Neblina) remains to be
determined when fertile material of the latter be-
comes available.

obtuse, elliptic leaflets with a mucronulate apex;
and conspicuous secondary nerves and tertiary ve-
nation.

This species differs from N. diffusa by having
reflexed flowers (even when young), larger sepals,
and much broader leaves with longer, stouter spines.
The four-pinnate inflorescences are also charac-
teristic. It is distinguished from N. hechtioides
Lyman B. Smith by having shorter sepals, the
posterior ones nonalate. From NV. brocchinioides
Lyman B. Smith, it is differentiated by the non-
digitate, solitary, shorter spikes.

described Navia liesneri and N. delascionis. The
interior leaves are white at the base as in N.
lascionis, but the more conspicuous teeth resemble
those of V. liesneri. The leaf blades are narrower

Hexapterella steyermarkii is only the second
species described in this genus. The other species,
H. gentianoides Urban, is a fairly common sap-
rophyte in Guyana and Surinam, and has been
collected once in Venezuela—at Cerro de la Ne-
blina, between 1,100 and 1,800 m. Hexapterella
steyermarkii is known from three collections in
Territorio Federal Amazonas (Cerros Aracamuni,
Neblina, and Autana) and one from Estado Bolivar
(Chimantá Massif).
The two species of Hexapterella can be distin-
guished by the following key:

Jablonski noted that the leaf venation and inflo-
rescence of this species suggested Senefeldera, but
e placed it in Sapium because of the staminate
flower with a two-lobed calyx and two connate
stamens. However, the branched inflorescence, ca-
ducous stipules, and especially the non-arillate seeds
of the type collection are quite incompatible with
Sapium. The small stamen number is shared with
Senefelderopsis, but that genus has unbranched
inflorescences and leaves with the veinlets not
prominulous. Surprisingly, there is a resemblance
to Mabea, especially to Mabea pohliana (Benth.)
Muell. Arg. in sect. Apodae Pax & Hoffman
(Pflanzenr. 147. V: 39. 1912). That species of
Mabea has a branched inflorescence, an androe-
cium of only two or three stamens, and an indu-
mentum of dendritic hairs. Yet Mabea pohliana
differs by having serrulate, short-petiolate leaves
without prominulous venation, discrete staminate
sepals and stamens, pedicellate pistillate flowers,
and an elongated stylar column. In its subsessile
pistillate flowers, elongated stylar column, and en-
tire leaves with prominulous venation, Senefeldera
yutajensis agrees with other species of Senefeld-
era, and this seems the best generic placement
despite the indumentum of dendritic hairs. Along
with Senefeldera triandra Pax & Hoffman (Pflanz-
enr. 147. XIV: 55. 1919) and possibly Mabea
paraguensis Muell. Arg. (Fl. Brasil 11(2): 527
1874), Senefeldera yutajensis may represent a
phyletic branch intermediate between the genera
Senefeldera and Mabea

ing characters are the brown tomentose pubescence
on the young parts, depressed-globose flower shape,
strongly developed basal pair of lateral veins on
the leaves. Another distinction is that no other
Licaria species in the Venezuelan Guayana is known
from the tepui summits, although L. macrophylla
(A.C. Smith) Kostermans is known from slopes of
Cerro Huachamacari at 600 m, L. tomentosa van
der Werff occurs on the slopes of the Chimantá
Massif.
Persea perseiphylla (Allen) van der Werff, comb.
nov. Ocotea perseiphylla Allen, Mem. New
York Bot. Gard. 10: 109. 1964
This species was known to Allen only from the
holotype (Schultes & Lopez 10103, US), a spec-
imen in young bud. Characters necessary for cor-
rect generic placement were not discernible at this
young stage, and Allen mistakenly placed the species
in Ocotea. Fruiting specimens show clearly that
this species belongs in Persea. Inspection of the
holotype also showed that the tepals of the buds
are unequal, with the outer three shorter than the
inner ones, a character found in most neotropical
Persea species but never in Ocotea. Hence Ocotea
perseiphylla is transferred to Persea. Because
open flowers have not yet been collected, P. per-
seiphylla cannot be placed in any of the sections
of subg. Eriodaphne Nees; the general resemblance
to P. maguirei L. Kopp and P. croatii van der
Werff suggests that it belongs in sect. Aurataea
Kopp. It has nine four-celled stamens and therefore
does not belong to sect. Hexanthera Kopp.

remotely appressed serrulate with 1-3 appressed
glandular teeth on uppermost 1.5-2 mm of mar-
gins, obtusely acute at apex with a blunt, glandular

This subspecies is distinguished from subsp. gui-
anense by having the leaf margins remotely ap-
pressed serrulate with 1—3 glandular teeth on each
side of the uppermost 1.5-2 mm of the margins,
and the leaf apex with a blunt, glandular protu-
berance. From subsp. sipapoensis Steyerm. it dif-
fers by the relatively few appressed glandular teeth
on each of the uppermost margins and the subor-
bicular rounded lamina of the staminode. It differs
from subsp. guaiquinimensis Steyerm., which has
a similar suborbicular rounded lamina, in the
rounded petals.

The generic revision of the Spiranthinae by L.A.
Garay (1982) formed the basis for a better un-
derstanding of the spiranthoid complex. A reeval-
uation of this group for a treatment of the Orchi-
daceae from the Venezuelan Guayana has revealed
the presence of a very distinctive new species that
cannot be assigned to any of the genera delimited
in Garay's revision.

styles Wawra complex, with which it shares the
small vegetative habit, nonresupinate flowers, and
sepals connate for at least part of their length.
However, Aracamunia differs from the other gen-
era of the KEurystyles complex in its terrestrial
habit, eciliate leaves and bracts, presence of lig-
ulelike structures, noncapitate inflorescences, and
ecristate sepals connate for about % of their length
(vs. up to 4% their length). Within the complex, it
seems to be closer to Eurystyles as defined by
Burns-Balogh et al. (1985), but in Aracamunia
the stigmas are confluent as in Pseudoeurystyles
Hoehne.
The most distinctive feature of Aracamunia is
the presence of the ligular, apparently glandular
structures that originate from the bases of the leaf
sheaths and persist even after disintegration of the
leaf blades and sheaths. These ligular structures
are erect, rigid, solitary, or (rarely) in pairs on each
leaf sheath. They show traces of vascular axes,
with phloem extending farther apically than the
xylem, suggesting a glandular function. The apices
age dentate, or expanded into a suborbicular
he multicellular hairs of the liguliform
structures are denser in younger more apical por-
tions, with each of the hair cells containing a large
nucleus proportionate to the size of the cells.
he ligular structures have vascular connections
with the leaf sheaths and the stem. Further study
is required to determine if they are glandular or
perhaps have an assimilative function.

This species is related to Rapatea steyermarkii
Maguire of extreme southeastern Venezuela in Es-
tado Bolivar. Although similar in inflorescence, in-
volucral bracts, and leaf shape and size, R. ara-
camuniana has filaments that are ciliolate (vs.
glabrous in R. steyermarkii). The anthers, lowest
bracteoles, and spikelets are longer in R. araca-
muniana. The upper and lower leaf surfaces of R.
steyermarkii are densely brown pubescent on the
lower surface with elongate, crisp-villosulous, loose
multicellular hairs, whereas in R. aracamuniana
the lower surface has only brown glandular dots
between smaller, pale punctations. In R. steyer-
markii the upper leaf surface has short, divaricate,
pointed hairs irregularly scattered on the nerves
in addition to a minutely papillate surface, whereas
the upper surface in R. aracamuniana is densely
verruculose-papillate throughout.

Cephalodendron was known until now as a
monotypic genus endemic to the summit of Cerro
de la Neblina in Venezuela. The new taxon differs
from C. globosum Steyerm. in the longer, spread-
ing-hirsute pubescence of stems, peduncles, peti-
oles, and lower leaf surface; longer calyx, corolla,
and anthers; and cylindric calyx tube 314-342 times
longer than broad.

elevated below, inconspicuous above. Petiole 1.5-
2 cm long, 2.5-3.5 mm wide, glabrous. Inflores-
cence terminal, paniculately branched, 8-10 cm
long including the peduncle, 6 cm broad at the
base, with 3 main divaricate tiers of lateral axes.
Flowering portion of inflorescence 6 cm long with
7-10 axes, the lower 4 proximate, 1-2 cm long
and branched into 3 secondary axes bearing capitu-
liform clusters 7-10 mm broad, each containing
5-10 sessile flowers; the other tiers of axes shorter,
1-3 cm long; rachis and axes minutely puberulent.
Peduncle 4-4.5 cm long, 2-2.5 mm wide, puber-
ulent. Calyx 4-lobed, deeply campanulate, 2.5 mm
long, 2 mm wide at summit, narrowed below, mi-
nutely puberulent without, sparsely puberulent at
the summit margin, glabrous within; lobes unequal,
squarrose, sublanceolate, obtuse at apex, 0.5 mm
ong, 0.2 mm wide, puberulent-ciliate; hypanthium
turbinate, 1.5 mm long, ] mm wide at summit,
minutely puberulent without. Corolla cylindric, api-
cally narrowed, 6 mm long, 1.5 mm wide (in bud);
corolla lobes 3 mm long (in bud). Stamens inserted
at base of corolla tube; anthers 2.5 mm long.
This species is related to Coussarea rudgeoides
Rusby of Bolivia and Peru, from which it differs
in the denticulately lobed calyx with pubescent,
squarrose lobes; longer peduncle; longer calyx tube
exceeding the hypanthium; and insertion of the
filaments at the base of the corolla tube. In C.
rudgeoides the filaments are attached in the lower
1⁄4 of the corolla tube, and the calyx tube is about
as long as the hypanthium.

The genus Veblinathamnus was originally de-
scribed by Steyermark (1963) with two species
known, N. argyreus from Venezuela on Cerro de
la Neblina and N. glabratus from adjacent north-
ern Brazil on Serra Pirapucü. This third species
differs from the other two in its shorter corolla;
larger leaf blades with subacute or obtuse apices;
and shorter, spathulate-linear, subacute calyx lobes,
which are more dilated at the apex, dorsally pu-
bescent, and more abundantly ciliolate.

This new species is notable for its inflorescence
of strictly one pair of flowers and its relatively
large, smooth capsular fruits that are apparently
nondehiscent. It is restricted to elevations above
m on sandstone in southern Venezuelan Gua-
yana (Cerros Neblina, Aracamuni, and Duida). It
is named in honor of Bassett Maguire, Senior Sci-
entist Emeritus of the New York Botanical Garden
and inveterate botanical explorer of the Guayana
Highland. Maguire and colleagues first. collected
this species in 1954, and he first directed my at-
tention to Ternstroemia as a genus in need of
taxonomic study.

& Smith, particularly var. granularis Maguire,
but the foliage and scapes are rugose and scabrid
(vs. smooth or granular), the sepal keels are sca-
bridulous (vs. smooth or granular), the petals are
blue (vs. white), and the seeds are smaller.

This is a near relative of Xyris frondosa Ma-
guire & Smith, a common high-altitude species of
the tepuis of Estado Bolivar, particularly in habit
and general leaf and spike dimensions. However,
it is somewhat shorter-stemmed, its leaves are en-
tire except at the very tips, and their margins more
wirelike and thickened. The scapes, rather than
being thick-edged and entire, are ancipital, the two
costas thin, broad, and distinctly pilose-ciliate.

gitudinally indistinctly nerved, olivaceous, gradu-
ally narrowed from middle to tip; tips narrowly
incurved-acute; margins entire, thin; sheaths car-
inate, thin, the sides longitudinally multicostate,
the margins gradually narrowed, at apex producing
a narrowly acute ligule 1.5-2 mm long, gradually
dilating below, long-ciliate at base. Scape sheaths
lax, open, slender and thin, cuspidate. Scapes sub-
terete, filiform, spirally twisted, 10-25 cm high,
ca. 0.4-0.5 mm thick, olivaceous, striate. Spikes
lanceoloid, drying turbinate, 7-9 mm long, few-
flowered, the entire bracts with broad, scarious pale
brown borders; sterile bracts ca. 6, subdecussate,
ovate, the lower pair carinate, shorter than the
inner pairs, 2.5-3 mm long; fertile bracts oblong-
ovate, 5-6 mm long, convex, rounded; dorsal areas
green, ca. 2 mm long, lanceolate-elliptic, medially
with an indistinct rib. Lateral sepals free, inequi-
lateral, curvate, 3-3.5 mm long, acute, the keel
broad, entire from base to middle, from middle to
apex low-lacerate. Petal blades obovate, 3-3.5 mm
long, yellow, broadly rounded, strongly erose.
Staminodia bibrachiate, the branches densely long-
penicillate. Anthers oblong-lanceolate, ca. 1 mm
long, emarginate and sagittate; filaments ca. 0.5
mm long. Mature capsule not seen, but the ovary
with marginal placentation and elongate funicles.
The growth habit of this species is somewhat
unusual. From the limited material available one
concludes that rosettes produce either scapes or
rhizomal buds from older axillae. The rhizomes are
elongate, zig-zag, and with short, evenly separated
leaves. The offshoots frequently branch and ulti-
mately produce new rosettes at the tips, the whole
proliferating product presumably forming extensive
clones. Mature seeds would be necessary to estab-
lish the relationship of this to others of the section

PRELIMINARY CHECKLIST OF
THE VASCULAR PLANT FLORA
OF CERRO ARACAMUNI
The checklist has been arranged into two groups:
pteridophytes and seed plants. Within each group,
families are arranged alphabetically and are divided
up into the four main areas of collection in the
following order: Summit, East Escarpment, Que-
brada Camp, and Granitic Dome. Within each of
the collecting areas, genus and species are listed
alphabetically. Each species is followed by the name
of the principal collector and number.
Details of the camp and collecting locations,
along with a list of the co-collectors with their
number ranges and dates of collection, are given

COMPOSITAE OF THE
GUAYANA HIGHLAND—IL.
NOVELTIES IN
GONGYLOLEPIS AND
STENOPADUS (MUTISIEAE)
John F. Pruski?
ABSTRACT
Described from the Guayana Highland are: Gongylolepis Ad Vea from Serra Aracá, Brazil, and from Sierra
de Unturán and Cerro de la Neblina, Venezuela;
megacephalus from Mount Ayanganna, Guyana.
species of both genera is given. Stomatochaeta eolv eei is transferred to Stenopadus and
Stenopadus aracaensis fro
m Serra Aracá, Brazil; and Stenopadus
xon are discussed and a key to
the combination Stenopadus
colveei is proposed. Additionally, five species from the Guayana Highland are newly documented for the flora of
razil.
The shrubby, homogamous, generally large-
headed Mutisieae are a striking element of the
Guayana Highland flora and are typically found
on tepui summits. Among Guayanan taxa of its
size—57 of the 6l currently recognized species
(93%) are endemic to Guayana — the Mutisieae are
unparalleled in their endemism level (Maguire,
1956; Pruski, 1989). The woody, hermaphroditic
members of the tribe Mutisieae from Guayana fall
into two main generic groups. The first group (sub-
tribe Mutisiinae sensu Cabrera, 1977) consists of
six genera having homogamous capitula composed
of don flowers and includes Gongylole pis
, with one species described herein. The
nud group (subtribe Gochnatiinae sensu Ca-
brera, 1977) contains four genera, which have only
actinomorphic flowers within their capitula. The
second group was previously represented in Gua-
yana only by Quelchia N. E. Brown and Steno-
padus S. F. Blake, but has been redefined to admit
two new genera, equivalent in part to species for-
merly placed in Stenopadus s.l. The newer genera
are Stomatochaeta (S. F. Blake) Maguire & Wur-
dack (1957), which was raised from subgeneric
level within Stenopadus, and Chimantaea Maguire
et al. (1957), which was described as new. All
subsequent authors (Aristeguieta, 1964, 1968;
Steyermark, 1980, 1984; Pruski, 1989) have rec-
ognized Stomatochaeta and Chimantaea, the ge-
neric status of which is justified by floral mor-
phology.
In this paper new species of Gongylolepis and
Stenopadus are described preliminary to my treat-
ment of the Compositae for the Flora of the Ven-
ezuelan Guayana by Julian Steyermark and col-
laborators, where the localities and complete
synonymies of all our Mutisieae will be given. Also,
fertile material of Stomatochaeta colveei, recently
made available to me for study, shows that this
species has the flower color and morphology typical
of Stenopadus, to which it is herein transferred.
GONGYLOLEPIS
Gong ylolepis is a genus of 15 species with bi-
labiate flowers and glabrous, reticulate, lanceolate
to obovate leaves. Fourteen of these occur in the
Guayana Highland and 11 are endemic to the
Venezuelan Guayana. The nearest generic relative
of dii us is the monotypic Eurydochus Ma-
guire & Wurda

STENOPADUS
Described and keyed below are two new species
of Stenopadus which, following the transfer of
Stomatochaeta colveei to Stenopadus, raises to
14 the number of species recognized in this genus.
All are endemic to the Guayana Highland and eight
species are restricted to Venezuelan Guayana.
Stenopadus is closely related to Stomatochaeta,
which was originally described as a subgenus of
Stenopadus. The yellowish corollas of Stomato-
chaeta (Fig. 2A, ABE with edi erect lobes much
longer than the t ti h it from Stenopadus
(Fig. 2C-E), which has magenta corollas with (at
maturity) coiled or flexuous lobes about as long as
or shorter than the tube. By these features generic
status for the two taxa is justified (Maguire &
Wurdack, 1957; Pruski, 1989).
Stomatochaeta colveei resembles Stenopadus
in a magenta corolla with tube longer than the
lobes. It was originally (incorrectly) described and
illustrated as having corolla lobes stiffly erect and
was thus placed by Steyermark (1980) in Sto-
matochaeta. Pruski (1989) noted it as possibly
intermediate between these two genera, but he
retained it within Stomatochaeta until flowering
o
material could be observed. Specimens examined
by me during a recent visit to the Instituto Botánico
in Caracas show that the corolla lobes of Stoma-
tochaeta colveei are flexuous and shorter than the
tube (Fig. 2E). Thus, this species fits well within
Stenopadus as envisioned here, and the formal
transfer of this species to Stenopadus is proposed
below

clearly apart from each other on the basis of flower
morphology. Furthermore, Stenopadus, a genus
of stately plants up to 25 m tall, is typically more
robust than Stomatochaeta, plants of which are
less than e m tall. Other genera from Guayana
only actinomorphic flowers, and
slightly less ied related to Stenopadus are Chi-
mantaea, which has abaxially tomentose leaves and
corolla lobes pilose when young, and Quelchia,
which has small, uniflorous capitula.

This species is a shrub 1.5-2.5 m tall charac-
terized by basally attenuate, oblanceolate leaves
and by narrowly cylindric, 5-6-flowered capitula.
It is endemic to Cerro Guaiquinima, where it occurs
in rocky or sparsely covered shrubby chaparral
from 900-1,350 m and flowers in December and
May.

Stenopadus aracaensis, collected on a recent
Projeto Flora Amazónica expedition, is most closely
related to S. kunhardtii. Both species have three-
nerved corolla lobes that are much shorter than
the corolla tube and thereby closely resemble one
another. However, S. aracaensis clearly differs
from S. kunhardtii by nonstipitate (vs. stipitate)
heads, smaller basally attenuate (vs. larger basally
cuneate) leaves, and capitula that contain 25 or
fewer (vs. 35-70) flowers. Also closely related is
S. huachamacari, but this differs from the two
mer species by two-nerved (vs. three-nerved)
corolla lobes that are about as long as (vs. much
shorter than) the corolla tube.

This paper continues a series dealing with chro-
mosome numbers of Compositae (Raven et al.,
1960; Raven & Kyhos, 1961; Ornduff et al., 1963,
1967; Payne et al., 1964; Solbrig et al., 1964,
1969, 1972; Anderson et al., 1974; Powell et al.,
1974, 1975; King et al., 1976; Tomb et al., 1978;
Robinson et al., 1981, 1985) and is the second
dealing with the tribe Eupatorieae (King et al.,
1976). New reports are provided for 13 genera
and 59 species (marked by **
in Appendix).
The new reports in this paper are based primarily
on material collected by R. M. King and counted
by A. M. Powell and J. F. Weedin (not coded) and
G. D. Carr (C). The chromosome counts have been
and * respectively
made from aceto-carmine or aceto-orcein squashes
of microsporocytes in meiosis. Voucher specimens
of the King collections are in US and a second set
is in MO
The previous paper in the series dealing with
the Eupatorieae summarized the numbers then
known from 327 of the approximately 2,000 species
and 70 of the 180 genera now known in the tribe.
The chromosome data were summarized again with
few additions in the survey of the tribe by King &
Robinson (1987). Studies subsequent to that of
King et al. (1976) have added reports of ten ad-
ditional genera: Urolepis n = 10 (Turner et al.,
1979; Waisman & Rozenblum, 1986); Hatsch-
bachiella n = 10 (Waisman & Rozenblum, 1986);
Lorentzianthus n = 10 (Bernardello,
Alomia n — 10 (Mabry et al., 1981; B
Turner, 1986; Sundberg et al., 1986); Amolinia
n — 10 (Strother, 1983); Flyriella n = 10 (Baker
Sí Turner, 1986; Sundberg et al., 1986); Eryth-
16, Eupatoriastrum n = 16; Kyr-
steniopsis n — 10; and Piptothrix n — ca. 17
(Sundberg et al., 1986).
The present paper adds chromosome counts for
the 13 additional genera: Bahianthus n — 10;
radenia n —
Bejaranoa n — 10; Bishovia n — ca. 10; Cron-
quistianthus n — ca. 10; Fleischmanniopsis n —
10; Goyazianthus n — 20; Platypodanthera n —
10; Pseudokyrsteniopsis n — 10; Sciadocephala

Chromosome Numbers in Compositae, XVI
n — 10; and Trichogonia n — 10. The new counts
of n — ca. 20 and ca. 26 for Kaunea seem to be
the first reasonably representative figures for the
genus. Chromosome numbers are now known from
94 of the 180 genera.
A few previously reported numbers are based
on vouchers needing corrections of identification.
The name Ageratina aschenborniana (Schauer)
K. & R. used in earlier papers is a synonym of A.
bustamenta, and Ophryosporus origanoides
[Meyen & Walp.] Hieron. is a synonym of O.
heptanthus. The plant reported by Coleman (1968:
235, Brazil: Coleman 295) as Ageratum cony-
zoides L. is Barrosoa betoniciforme (DC.) K. & R.
The general pattern of chromosome numbers in
the tribe was first presented in King et al. (1976).
Thirteen of the 18 subtribes had a base of x — 10
or clearly derived numbers, such as x — 15. The
remaining five subtribes show higher base numbers
with no remnant of x = 10. As elaborated from
the chart in King & Robinson (1987), the subtribes
have the following numbers with primary bases in
boldface: Adenostemmatinae 5, 10; Eupatori-
inae 10, 15, 20; Disynaphinae 10; Gyptidinae
10; Ageratinae 9 (Acritopappus), 10, 11, 12
(Microspermum- Piqueria-Stevia group), 15, 20,
25; Trichocoroninae 15; Ayapaninae 10; Alo-
miinae 9 (Brickellia group), 10; Liatrinae 10,
20, 30; Fleischmanniinae 4 (Fleischmannia
microstemon), 10, 20, 30; Critoniinae 10, 20;
Praxelinae 10, 20, 29; Hebecliniinae 10, 16;
Neomirandeinae 17, 20, 24, 25; Mikaniinae 16,
17, 18, 19, 20; Oxylobinae 16, 17, ca. 20, 51;
Hofmeisterinae 18, 19; Oaxacaniinae 18. The
pattern has not been altered by any of the more
recent reports, and it is actually greatly reinforced
by numerous new chromosome counts in the sub-
tribes Ageratinae, Fleischmanninae, Hebecliniinae,
and Oxylobinae. The only questionable additions
since 1977 are in the Critoniinae and Hebeclini-
inae. Questionable counts have often been over-
turned by subsequent examination of vouchers, as
in the case discussed under Kaunea in the Oxy-
lobinae, or by reexamination of the species. The
patterns seem well established, and deviations should
be carefully rechecked.
The significant new reports are best reviewed in
the order of the subtribes established in King &
Robinson (1987).
ADENOSTEMMATINAE
The new report of n = 10 for Sciadocephala
is the first for that genus and the first in the subtribe
outside of Adenostemma. Evidently both genera
retain the basic number of the tribe. There has
been no further evidence in the subtribe for the
low n = 5 reported by Turner & Irwin (1960)
from a plant now determined as 4. involucratum.
Our new report for that species is n = . The
two genera of the subtribe with the anomalous
knob-formed pappus have now been counted, but
the remaining genus Gymnocoronis, which lacks
such a pappus, is still unstudied.
EUPATORIINAE
The Waisman € Rozenblum (1986) count for
Hatschbachiella completes the survey of genera
in the subtribe. All four genera show a base of x
= 10, with Eupatorium (including Eupatoriadel-
phus) showing some triploids and tetraploids.
GYPTIDINAE
The new generic reports for Bahianthus, Be-
jaranoa, Litothamnus, Platypodanthera, and
Trichogonia, and the Urolepis counts (Turner et
al., 1979; Waisman & Rozenblum, 1986) show
that n = 10 is basic to the subtribe. The recent
cytological study of Gyptis pinnatifida Cass. (as
Eupatorium tanacetifolium Gillies ex Hook. &
Arn. by Rozenblum et al., 1988) confirms the
triploid condition based on n = 10 that is already
known to occur in that genus and examines details
of the apomixis in the species.
AGERATINAE
The many new counts of Acritopappus, based
on four species, strongly confirm the occurrence
of n = 9 first noted for one of the species by
Coleman (1970) and mentioned by King et al.
1976). The isolated occurrence of n = 9 in Ac-
ritopappus is apparently consistent for the genus,
with reports from both viscid-leaved and non-viscid-
leaved members. Prior to the discovery of n = 9
in Acritopappus, the number was known in the
tribe from only Brickellia and its close relatives
in the subtribe Alomiinae.
ther reports of chromosome numbers of Age-
ratinae since King et al. (1976) confirmed other
known patterns. New counts of Ageratum spp.
show a base of 10. The Dillon & Turner (1982)
report of ca. n = 10 for Ascidiogyne sanchez-
—
vegae Cabrera conforms with the n — 10 already
known for the type species 4. wurdackii Cuatr.
This further indicates the difference between the
latter genus and the members of the Piqueria
relationship. New reports from Piqueria and Stevia
and the Strother (1983) and Sundberg et al. (1986)
1006
Annals of the
Missouri Botanical Garden
reports for Microspermum debile Benth. and M.
nummularüfolium Lagasca conform to the already
known bases of n — 12 and n — 11 in that group.
The South American species reported for Stevia
all have n — 11, and none show the n — 12 found
in shrubby members of the genus in Central Amer-
ALOMIINAE
he new generic counts for Goyazianthus,
Planaltoa, and Pseudokyrsteniopsis; generic
counts by others for Alomia, Flyriella (Baker &
Turner, 1986; Sundberg et al., 1986) and Kyr-
steniopsis (Sundberg et al., 1986); and the counts
for all three species of Carminatia (Turner, 1988)
extend our knowledge of elements of the subtribe
having the base number of 10. The Turner report
for his new species, Carminatia anomala, is here
attributed to the earlier name for the species, C.
alvarezii Rzed. & Calderón de Rzedowski (1987).
Chromosome numbers of the genera could all be
anticipated on the basis of their evident relation-
ships within the subtribe. The number n — 9 that
is notably present in the Alomiinae in Brickellia
(King et al., 1976; Keil et al., 1988), Barroetea
(Sundberg et al., 1986), Pleurocoronis, and their
immediate relatives is unknown in any of the pri-
marily South American genera of the subtribe.
LIATRINAE
The new chromosome count for Hartwrightia
completes the survey of the six genera of this small
subtribe from the southeastern United States. All
members of the subtribe have n = 10 or polyploids
of that number.
FLEISCHMANNIINAE
The numerous new reports for Fleischmannia
firmly establish n — 10 as the base for most of the
species. No further examples have been found of
the n — 4 that is characteristic of the weedy annual
F. microstemon (Cass.) K. & R. and that has been
reported for F. hymenophyllum by Grashoff et al.
(1972).
The counts reported in the present study formed
the basis for statements regarding the polyploid
complex first noted by King & Robinson (1978,
1987) in Central America. The geographically re-
stricted Guatemalan species Fleischmannia bohl-
manniana K. & R., F. deborabellae K. & R.,
and F. viscidipes (B. L. Robins.) K. & R. prove
to be diploid, while the more widely distributed
weedy species F. pratensis (Klatt) K. & R. and
F. pycnocephala (Less.) K. & R. continue to show
a consistently polyploid condition.
CRITONIINAE
The three new generic reports for the subtribe
(Bishovia K. & R., Cronquistianthus K. & R.,
and Fleischmanniopsis) and the Lorentzianthus
count of Bernardello (1986) show the base of n —
10 that is characteristic of all previously known
members of the group. The only serious suggestion
of another base in the subtribe seems to involve
the presently uncounted genus Eupatoriastrum,
which is noted for its paleaceous receptacles. The
species belonging to this genus have been associ-
ated with a similarly paleaceous species, Fupato-
rium corvi McVaugh (McVaugh, 1972) of Chia-
pas, which has an n = 16 (King et al., 1976). The
latter is now recognized as the genus Matudina of
the subtribe Hebecliniinae, and shows no detailed
structural evidence of immediate relationship to
‘upatoriastrum. In contrast, structural features
of Eupatoriastrum suggest close relationship to
Koanophyllon, which has numerous reports of a
base of n = 10 in this study and in previous studies
based on Central and South American material
(King et al., 1976; Keil et al., 1988).
Therefor: it is surprising to see a report of n
= l6 from Fupatoriastrum nelsonii Greenman
(Sundberg et al., 1986). The voucher cited by
Sundberg et al. from Coatepec, Veracruz (Her-
nández 320) has been sought for study, but the
specimen is not deposited at TEX as indicated. The
actual repository, XAL, has not replied. A specimen
of E. nelsonii (Hernández 355 TEX), collected
from the same place, is correctly determined. The
latter is the voucher for the chemical study by
Bohlmann et al. (1985). It is possible that the n
= 16 reported from Eupatoriastrum nelsonii is
correct, and that the genus is a member of the
Hebecliniinae rather than the Critoniinae. No char-
acteristic of the genus precludes this. In fact, the
form and texture of the corollas of Fupatoriastrum
are rather like that of various members of the
Hebeclinium group. Structural details indicate that
placement within the Hebecliniinae, if correct, would
be closer to Decachaeta than Matudina. Although
the structural characters of the Hebecliniinae are
less definite than those of most subtribes, there is
no reason to believe that n = 16 has arisen more
than once from x — 10.
King et al. (1976) placed Peteravenia in the
Hebeclinium group and reported chromosome
numbers of n — 10 and n — ca. 17. The genus
was transferred to the Critoniinae in King & Rob-

Robinson et al. 1007
Chromosome Numbers in Compositae, XVI
inson (1987), where the report of n — ca. 17 was
rejected from the genus as the voucher proved to
be Ageratina subinclusa (Klatt) K. & R. Two new
counts further establish n — 10 as the base number
for Peteravenia.
PRAXELINAE
New reports for Chromolaena and Praxelis (Ap-
pendix) and reports in recent literature (Sundberg
et al., 1986) show the trend already known for
high chromosome numbers and irregular meiosis
in the subtribe.
HEBECLINIINAE
King et al. (1976) noted the Hebeclinium group
for the presence of two distinct base numbers, x
= 10 and x = 16. The members of the subtribe
with n = 10 were Hebeclinium and the South
American species of Bartlettina. In contrast, the
Central American genera Erythradenia (Sundberg
et al., 1986), Decachaeta, and Matudina, and the
Central American species of Bartlettina showed n
— 16. The geographical pattern seemed to be most-
ly South America versus Central America, with
Hebeclinium being basically South American. Sub-
sequent reports have generally confirmed the pat-
tern. Strother (1983) reported n — 16 for four
Central American species, Bartlettina breedlovei
K. € R., B. pansamalensis (B. L. Robins.) K. &
R., B. pinabetensis (B. L. Robins.) K. & R., and
B. tuerckheimii (Klatt) K. & R., and the same
number was reported by Sundberg et al. (1986)
for B. hintonii K. & R. In an apparent exception
to the characteristic n — 16, two Central American
species of Bartlettina tamaulipanum (B. Turner)
K. & R. and Eupatorium xalapanum B. Turner
(7 B. brevipetiolata (Schultz-Bip. ex Klatt) K. &
R.) have been reported as n = 10 (Turner, 1985).
The types have been seen, and they are clearly
members of the Central American complex in the
genus. The reports of n — 10 are greatly in need
of confirmation.
The only basically Central American element of
the Hebecliniinae presently known with n = 1
seems to be Amolinia heydeana (B. L. Robins.)
K. & R. reported by Strother (1983).
NEOMIRANDEINAE
New reports for this monogeneric tribe include
one species of each subgenus of Neomirandea. The
reports of n = 17 for N. eximia agree with earlier
counts. The reports of n = ca. 26 for N. angularis
are the first of that number in the genus, but they
offer limited consistency in a member of the typical
subgenus of Neomirandea, which has previously
been reported variously as n — 20, n — ca. 24, n
— ca. 25 (King et al., 1976), and the species has
recently been reported as n — 25 by Sundberg et
al. (1986).
OXYLOBINAE
Reports since King et al. (1976) have provided
an expected count of n — ca. 17 for Piptothrix
(Sundberg et al., 1986) and supported previously
known chromosome patterns of n — 16 for Oxy-
lobus (Turner & Kerr, 1985) and n —
Ageratina subgenera Ageratina, Neogreenella,
and Klattiella (Jansen et al., 1984; Sundberg et
al., 1986). Strother (1983) noted a minor Ss
}
17 in
ture of n = 18 for Eupatorium subp
(= Ageratina subinclusa (Klatt) K. & R. The
present study, Jansen et al. (1984), and Waisman
& Rozenblum, (1986) give further examples of the
subgenus Andinia, i.e., Ageratina ampla (Benth.)
, A. dendroides, A. pseudochilca, A.
Dr. (Hieron.) K. & R., 4. angustifolia
(H. B. K.) K. € R., 4. dee (Benth.) K. &
Ry A baccharoides (H. B ) K. & R., and 4.
elegans (H. B. K.) K. & E ue counts confirm
the consistent n — ca. 40 and n — ca. 42 already
seen by King et al. (1976) in the subgenus except
for the higher polyploid n — ca. 90 count for 4.
angustifolia by Waisman & Rozenblum (1986).
The new count of n = ca. 20 for Kaunea ig-
norata seems to reinforce the generally high num-
ber 2n — near 45 found by Royce Oliver in root
tips of that species (King & Robinson, 1980). The
new report of n = ca. 26 for Kaunea lasioph-
thalma conflicts with an earlier report of n — 10
for Eupatorium lasiophthalmum Griseb. (Turner
et al., 1979), but the voucher for the latter report
has been examined and proves to be Lorentzian-
thus viscidus, a species known to have an n —
10. It seems that Kaunea characteristically has a
chromosome number at the level of n = 20-26,
which is consistent with higher
known members of subtribe Oxylobinae. The higher
numbers in Kaunea are reminiscent of those of
another Andean member of the subtribe,
tina subg. Andinia. Nevertheless, the numbers in
the two groups do not seem to be the same, and
if other aspects of the plants are any indication of
relationship, the higher numbers evidently origi-
nated separately. Structurally, Kaunea seems to
be one of the most divergent elements of the Oxy-
lobinae, and it is not now considered close to any
numbers in other
Agera-
part of Ageratina.

A GEOGRAPHICAL
ANALYSIS OF THE
FAMILY RANUNCULACEAE
Svetlana N. Ziman! and
arl S. Keener?
ABSTRACT
The Ranunculaceae Juss. are distributed worldwide.
place in the vast territory of Eurasia during the Paleogen
time. The western and eastern floristic centers in eastern Pes played the m
differentiation (i.e., formation of most g
primary differentiation of this family apparently m
at least 50 million years ago
The aim of this paper is to analyze the role of
the Ranunculaceae with respect to floras around
the world and to define more precisely some ques-
tions concerning the origin and differentiation of
e, there is no general study of the geo-
graphical distribution of the Ranunculaceae as a
whole, except those of Tamura (1966-1968), whose
data on the presence of species in the various
floristic regions of the earth were helpful in pre-
paring this essay. Additianalys we took advantage
of our own herba rium t
from KW, LW, LWS, LE, TBI, TAD, BP, and
others) and the observations of the senior author
ai
w the iterpaetaticd of the floristic re-
gions tep provinces (Table 1 and map) by T
tajan (1970, 1978) and the interpretation d en-
in the sense of Tolmachev (1974).
Furthermore, we have attempted to recognize local,
disjunctive, and widespread endemic species within
each province or region.
GEOGRAPHICAL CHARACTERISTICS OF THE
ANUNCULACEAE
The Ranunculaceae comprise 55 genera and
about 2,200 species (Takhtajan, 1987; Tamura,
1966-1968; Ziman, 1985). About 20 genera’ and
1,200 species are endemics (Table 2). Some en-
demic genera, e.g., Beesia, Souliea, Kingdonia,
Asteropyrum, and Xanthorhiza, are morphologi-
cally isolated within the Ranunculaceae, and thus
we were able to use their areas to discuss pecu-
liarities of the distribution and the differentiation
of the family as a whole.
To date, five floristic regions, the Eastern Asiat-
ic, Atlantic North American, Andean, Chile-Pa-
tagonian, and Irano-Turanian, contain at least one
endemic genus.
Most genera of Ranunculaceae have disjunctive
distributions. Some, e.g., Calathodes, Dichocar-
pum, Urophysa, Semiaquilegia, Beesia, Souliea,
and Kingdonia, occur within restricted geographic
ranges of two to four provinces in one region.

Geographical Analysis of Ranunculaceae
phis, Paraquilegia, and Callianthemum, is char-
acterized by more or less widely disjunctive areas,
occupying two to four regions of Eurasia.
Areas of a third group, which includes Trollius,
Actaea, Cimicifuga, Enemion, Pulsatilla, He-
patica, Halerpestes, and Trautvetteria, are rep-
resented in three to seven regions of Eurasia and
North America. In many cases the disjunctive
species of these genera are considered as relicts of
the Tertiary temperate flora (Thorne, 1973).
Species of Caltha and Myosurus are widely
distributed in the Northern and Southern hemi-
spheres. It is remarkable that they are widespread
in temperate areas but absent in the tropics and
subtropics.
The distributional patterns of the remaining 18
genera of Ranunculaceae are unbroken or nearly
unbroken. Species of the majority of them occur
in two to six regions of Eurasia (Aconitella and
Ficaria), Sout
America (Hamadryas), Africa (Knowltonia and
Clematopsis), Eurasia, North Africa and North
America (Nigella, Aconitum, Consolida, Aquile-
gia, Adonis, Ceratocephalus, and Coptis). Del-
Southeastern Asia (Varavelia),
phinium occurs in 11 regions of Eurasia, Africa,
North America, and South America; Thalictrum
occurs in 16 regions on these continents. Species
of Anemone, Clematis, and Ranunculus are wide-
spread in both hemispheres in the floras of about
30 regions.
REGIONAL DISTRIBUTION OF THE
RANUNCULACEAE
In following Takhtajan (1978) we examined the
distribution patterns of the Ranunculaceae in six
floristic kingdoms, eight subkingdoms, 34 regions,
and about 150 provinces.
HOLARCTIC KINGDOM
Location: territories of the Northern Hemi-
sphere (more than half of the Earth), including
Europe, extratropical Asia, North America, and
North Africa.
Climate: predominately temperate, partly sub-
tropical, and cold
Ranunculaceae: 49 genera, 2,000 species.
Boreal Subkingdom
This subkingdom includes four regions: Eastern
Asiatic, Circumboreal, Atlantic North American,
and Rocky Mountain.
Location: extratropical Eurasia and North
America.
Ranunculaceae: 48 genera, 1,500 species.
Eastern Asiatic Region
Location: main part of continental China, north-
ern India, Burma, and Nepal, almost all Japan and
Korea, eastern U.S.S.R
Climate: warm temperate to mostly temperate.
Ranunculaceae: 38 genera, 900 species; 12
endemic genera, 400 endemic species.
Sikang Yunnan Province
Location: highlands; main part of the Chinese
provinces Szechwan, Kweichow, and Yunnan, also
northeastern Burma and northern Laos.
aracteristic vegetation: mountain conifer-
ous, broad-leaved and rain forest, subalpine, and
alpine formations.
Ranunculaceae: 28 genera, 400 species (14,
42, 48, 66, 81, 84, 109, 112, 199, 316).
Related floras: Central Chinese (21/60) and
Eastern Himalayan (19/70).
Observations: 8 endemic genera, 180 endemic
species. All endemic genera are isolated morpho-
logically within the family. For example, Astero-
pyrum (A. peltatum) represents the monotypic
tribe Asteropyreae and differs from other species
by having simple peltate leaves. One other genus,
Souliea (S. vaginata), belongs to the tribe Cimi-
cifugeae and is distinguished by a unique type of
ollen grain which lacks a primary germination
apparatus (171). Another endemic monotypic ge-
nus, Kingdonia (K. uniflora), is exceptional by
having open dichotomous foliar venation (42). This
genus makes up the monogeneric tribe Kingdon-
ieae, subfamily Kingdonioideae.*
also Urophysa henryi, Beesia calthifolia,
athodes palmata, C. polycarpa, and C. oxycarpa,
occur in isolated mountain forest locations at 2,000—
4,000 m of the Sikang Yunnan, Central Chinese,
Eastern Himalayan, and some other provinces.
Disjunct areas of species of Semiaquilegia (S.
adoxodoides and S. manschurica) and Dichocar-
pum (D. fargesii, D. dicarpon, and others) are
widely separated in provinces in the west and the
east of the Eastern Asiatic Region. These species
are also mountain forest plants, restricted to shade
locations.

In the flora of the Sikang Yunnan Province,
Aconitum has about 70 species of which 40 are
endemics; Delphinium has 70 species and 50 en-
demics; Clematis has 40 and 20; Anemone 20
and 15; Trollius 10 and 8; and Aquilegia 8 and
9 species.
In this province occur species that are important
in considering the origin and dispersion of their
genera and the family Ranunculaceae as a whole.
For example, Aconitum gymnandrum, which rep-
resents the monotypic subg. Gymnaconitum, is
found at about 4,000 m in Szechwan and in the
Eastern Himalayan Province. Its annual habit is
unique within Aconitum; this species is character-
ized by having primitive flowers and is considered
a Tertiary relict (181, 241, 284). Another prim-
itive species, Delphinium aconitoides, also occurs
in this province. The local endemic Clematis ran-
unculoides, occurring there, represents the mono-
typic sect. Ranunculoides, and its life form (ro-
sette-forming perennial herb with tripartite leaves)
is regarded (341, 342) as the most primitive within
Clematis.
There are three monotypic endemic sections of
Anemone: sect. Rivularis (A. rivularis), sect. Ane-
moclema (A. glaucifolia), and sect. Begoniifolia
(A. begoniifolia). Moreover, the most primitive
and simultaneously relict species of Trollius (T.
yunnanensis) (64, 270) and Aquilegia (A. ecal-
ta) in the Sikang Yunnan Province (272).
The few species endemic to this province include
Delphinium ceratophorum, Ranunculus platy-
petalus, and Thalictrum delavayi; many other
species are shared with adjacent provinces.

bashan and Nanlin, and the southern part of the
Yangtze Basin (Kiangsu, Shensi, Hupeh, Anhwei,
and Hunan provinces of Chin

species. (The endemic genera, Asteropyrum, Uro-
physa, Kingdonia, Souliea, Beesia, Calathodes,
and Dichocarpum, are shared with the flora of
Sikang Yunnan.) Most of the endemic species be-
long to Aconitum, Delphinium, Clematis, and
Thalictrum. Endemic Helleborus chinensis to-
gether with H. thibeticus represent the endemic
sect. Dicarpon. In contrast with the Sikang Yun-
nan flora, some species of Pulsatilla, e.g., P. chi-
nensis, and P. turczaninovii are distributed here.

Observations: 6 endemic genera, 190 endemic
species. Four of the endemic genera are shared
with Sikang Yunnan Province, whereas Archiclem-
atis and Paroxygraphis are local only. Archiclem-
atis alternata grows in central Nepal in bushy
border habitats at 2,200 m; Paroxygraphis sik-
kimensis is found in Sikkim in the alpine zone at
4,000 m. There are two endemic, monotypic sec-
tions of Aconitum: sect. Fletcherum (A. fletcher-
anum) and sect. Alatospermum (A. novoluridum),
also the endemic, monotypic Thalictrum—sect.
Piuttia (T. rotundifolium). Most endemic species
belong to Delphinium (in all about 50 species with
about 30 endemics, e.g., D. nepalense), Aconitum
(30 and 20, e.g., A. spicatum), Ranunculus (30
and 10, e.g., R. hirtellus), and Thalictrum (20

The flora of the Eastern Asiatic Region is an
extraordinary mixture of tropical and temperate
elements, and is considered (296, 297) as the most
significant center of development of the Angio-
sperms, possibly the area of origin.
ithin this region the flora of the Sikang Yun-
nan Province is extremely rich with Angiosperms;
therefore, some Soviet plant geographers (159,
38) regarded Southwestern China as the
cradle of the modern temperate flora of Eurasia
and considered the latter as derived from an ancient
tropical flora. Other botanists (78, 107, 109) sug-
gested that the primary development of the tem-
perate mesophytic forest flora of Eurasia took place
within the Eurasiatic tropical flora, possibly within
Southwestern China, which has been the greatest
refugium for this temperate flora.
According to the paleobotanical data (131), since
Late Cretaceous time the Sikang Yunnan flora
was mainly a high-mountain one, which included
many temperate elements. The Yunnan Plateau is
one of the most ancient mountain systems, formed
in the Late Cretaceous (Yanshan movement of the
earth crust— 224), while the Himalayas are much
more recent and belong to the alpine stage of
mountain development (192). Therefore, the East-
ern Himalayan flora is considered young (297).

Some plant geographers (13,
the Manchurian flora was a
the Tertiary warm temperate forest flora and sug-
gest that the former coniferous-broad-leaved me-
sophytic forests, in which temperate elements now
predominate, migrated there during the Miocene
and
changed since.
According to Maekawa (190), a warm temperate
flora developed in Japan and Korea since the Oli-
flora of Manchuria has scarcely
gocene-Miocene. Tanai (304) claimed that the me-
sophytic coniferous-broad-leaved forests that sur-
vived there are quite similar to those in Manchuria.
Our analysis of the role of the Ranunculaceae
in the provincial floras of the Eastern Asiatic Re-
gion led us to postulate that the initial differentia-
tion of many groups of this family took place there
in two diverse floristic centers, western and eastern
ones. The former includes the Sikang Yunnan,
Eastern Himalaya, and adjacent territories, the
latter coincides with Manchuria, Japan, and Sa-
alin.
The western floristic center consists of ten en-

provinces of eastern Asia and only Archiclematis
and Paroxygraphis are local Eastern Himalayan
endemics.
Most of the endemic ranunculaceous species
within the western floristic center of eastern Asia
are high mountain plants, and in this area a number
of species are shared with two or three adjacent
provincial floras. There are 22 genera and about
60 species ees about 20 endemics) in com-
mon with the Sikang Yunnanian, Eastern Hima-
layan, and Central Chinese provincial floras. These
floras consist of the most primitive species of Trol-
lius (T. yunnanensis), Anemone (A. rivularis),
Clematis (C. ranunculoides), and Aquilegia (A.
ecalcarata), and all of these genera include sec-
tions endemic to the western part of eastern Asia.
Compared with the eastern floristic center, the
western one is home to species of the disjunctive
Eurasiatic genera Helleborus, Paropyrum, Par-
aquilegia, and Oxygraphis.
All these facts confirm our opinion concerning
the close connections of the floras of the previously
entioned western provinces of eastern Asia. In
i region of these western provinces during past
geological periods a single high-mountain flora ex-
isted which became a center of development for
several genera of the Ranunculaceae (all ten en-
demic genera, also Trollius, Aconitum, Aquilegia,
Anemone, and Clematis). We do not consider the
Ranunculaceae in the Eastern Himalayan Province
as consisting of young species; rather, we support
the opinion of van Steenis (289) about their antiq-
uity.
The eastern floristic center in eastern Asia con-
sists of four endemic ranunculaceous genera and
about 120 endemic species. Two endemic genera,
Semiaquilegia and Dichocarpum, are shared with
the western center and the other two genera, Ane-
monopsis and Miyakea, are local endemics.
Most endemic species of Ranunculaceae in the
eastern part of eastern Asia are montane forest
plants. There are 17 genera and about 25 species
shared by Manchuria, Japan, and Sakhalin, but
there are almost no endemic species shared by two
or three provinces. These floras consist of endemic
sections of Cimicifuga, Anemone, Pulsatilla,
Clematis, and Coptis. In contrast to the western
floristic center, in the eastern center occur species
of the disjunctive Palearctic genera Enemion and
Trautvetteria, comparatively few species of Del-
phinium (absent in Japan and Sakhalin), and com-
paratively few Clematis species (especially few in
Manchuria).
A comparison of the roles of the Ranunculaceae
in the provincial floras of the western and eastern
parts of eastern Asia indicated that only one-third
of the ranunculaceous genera are common to
both areas (Caltha, Trollius, Actaea, Cimicifuga,
Aconitum, Delphinium, Aquilegia, Anemone,
Pulsatilla, Adonis, Thalictrum, Ranunculus), and
all of them are shared with the flora of the Cir-
cumboreal Region.
The facts obtained as a result of our analysis
are probably best explained on the basis of the
hypothesis that the Ranunculaceae probably orig-
inated in the vast land mass of Eurasia, with east-
ern Asia as a most significant center of secondary
differentiation and conservation of many ranun-
culaceous genera. There were two centers of for-
mation for genera and species of Ranunculaceae,
western and eastern, which developed rather in-
dependently, though some groups migrated from
one to the other. In our opinion, in the high-moun-
tain flora of Sikang Yunnan, the Eastern Hima-
layas, and adjacent territories the endemic genera
Asteropyrum, Beesia, Calathodes, Souliea, Uro-
physa, Kingdonia, Archiclematis, and Paroxy-
graphis evolved, as did such genera as Trollius,
Aquilegia, Anemone, and Clematis. Meanwhile,
in the montane forest flora of Manchuria, Japan,
and adjacent territories, the endemic genera Ane-
monopsis, Miyakea, Semiaquilegia, and Dicho-
carpum evolved.
Plant geographers (77, 136, 166) regarded the
Altai as the refugium of the Tertiary nemoral relicts
and one of the important centers of development
of the high-mountain Eurasiatic flora. They pro-
posed that many ancient Eastern Asiatic species
migrated westward through the Altai. Our data on
the Ranunculaceae confirm the importance of the
Altai flora in the development and distribution of
many Eurasiatic groups of Angiosperms. Further-
more, endemic genera and sections of the Ranun-
culaceae in the Siberian provincial floras are ab-
sent, and moreover, almost no species occur in all
provincial floras of Siberia. These facts can be
explained if one is to Ern that contacts of
Siberian floras were not clos
According to Tikhomirov (308) and Vasiljev
(321), the origin of Siberian taiga floristic com-
plexes are recent (Pleistocene), but Tolmachev (310)
claimed that these complexes were more ancient
(Early Pliocene). Our data support the latter opin-
ion but show that the floristic elements of the Ra-
nunculaceae of the northern Siberian taiga were
derived from Eastern Asiatic ones. Consequently,
some Siberian species of Trollius, Aconitum, Del-
phinium, Anemone, Ranunculus, and Thalictrum
are considered today as boreal or taiga elements,
ut they are really related to the nemoral high-

Geographical Analysis of Ranunculaceae
mountain elements of the more warmth-loving flo-
ras of Manchuria and western China.
Our analysis of the Ranunculaceae of the pro-
vincial floras of Europe shows the presence of 25
genera and about 250 species. Endemic ranun-
culaceous genera are absent, but there are about
5 endemic species restricted mainly to the Alps,
Carpathians, Pyrenees, and other highlands, and
include species of Aquilegia, Aconitum, Delphin-
ium, Ranunculus, and Thalictrum.
The distinctive features of the European pro-
vincial floras include not only the presence within
them of many common ranunculaceous species but
also historical connections with the Siberian and
especially with the Eastern Asiatic floras. Accord-
ing to Popov (236), the Eastern Asiatic and Eu-
ropean floras have the same age, but our data show
that the latter are derivative from the former. In
our opinion, therefore, the majority of the Tertiary
ranunculaceous groups have migrated into Europe
from the east during the Pliocene and became
preserved there in the Alps, Carpathians, and other
mountains. More recently, in these territories in-
tensive radiation of new groups of Aconitum, Del-
phinium, and Aquilegia took place.
Our data from analysis of the role of the Ra-
nunculaceae in arctic regions uphold the opinion
of Tolmachev (312) and Budantsev (36) concern-
ing the comparatively recent age of the arctic
floristic complexes and their derivation from boreal
and partly from nemoral complexes. Contrary to
some plant geographers (95, 314, 320) who con-
sider the territory of the Arctic Province as a
floristic region or a special zone without division
into regions and provinces, we follow Takhtajan's
(2977) interpretation of this province.
aucasus was a remarkable center in the
formation of some high-mountain groups of An-
giosperms in the Late Pliocene and Pleistocene (77,
101, 102, 193, 293). These groups originated out
of subtropical-forest species (complexes of the Pol.
tava flora— 1 70), but some of them migrated there
from the east, mainly from eastern Asia.
We note also the presence within the modern
Caucasian flora of 22 genera and about 230 species
of Ranunculaceae (about 60 endemic). Almost all
ranunculaceous genera in the Caucasian provincial
floras are shared with those in the European and
Siberian floras of the Circumboreal Region. Most
species of these genera (Aquilegia, Aconitum, Del-
phinium, Anemone, Pulsatilla, Clematis, and
Thalictrum) occur in eastern Asia and Siberia.
Some genera (e.g., Nigella, Consolida, Cera-
tocephalus) occurring in the Caucasian floras are
shared with the floras of the Mediterranean Region.
In the flora of the Caucasus, there are some Eu-
rasiatic disjuncts (e.g., Actaea spicata, Anemone
nemorosa), which are generally accepted as Ter-
tiary relicts. These data led us to hypothesize close
connections among the ranunculaceous groups in
Eurasia (including the Caucasus) during past pe-
riods and to hypothesize possible migrations of their
ancestral groups into the Caucasus from the east.
The membership within the Ranunculaceae of
large numbers of Caucasian endemics indicates lo-
cal differentiation of this family in the high-moun-
tain zones, especially within Delphinium and Ra-
nunculus. Most of the Caucasian endemic species
(e.g., Aquilegia colchica, Delphinium pyrami-
datum, Anemone speciosa, Aconitum pubiceps,
Ranunculus helenae) originated in the Western
Caucasus (or Colkhis), which is considered to be a
significant refugium of the Late Tertiary warm-
temperate forest flora. Another large Tertiary flo-
ristic refugium, which was in the Eastern Caucasus
Hyrcan or Talysh), did not play a large role in
the differentiation of the Ranunculaceae and hence
—
the Talysh endemic species of this family are not
numerous. The evolution of the ranunculaceous
flora of these two centers developed independently,
and shared endemics as well as vicariant species
of Ranunculaceae are almost absent.
Some species of Ranunculaceae in the Caucasian
floras are shared with the Mediterranean Region
or are closely related to species there. They are
predominately annual xerophytes (e.g., Nigella ar-
ensis, Consolida ambigua, Ceratocephalus tes-
ticulatus, Adonis aestivalis). The Caucasian ran-
unculaceous species with connections in Anterior
Asia are xerophytic and mainly annual (e.g., Del-
phinium cyphoplectrum, Consolida divaricata,
igella orientalis, Aconitella hohenackeri, Tha-
lictrum sultabadense). At the same time, within
the ranunculaceous species shared between the
are high-moun-
tain, mesophytic, mainly forest plants (e.g., Caltha
polypetala, Trollius Aquileg
caucasica, Anemone impexa, Pulsatilla RR
Caucasus and Asia Minor, many
ranunculinus,
cea).
All previously mentioned data led us to suggest
close connections of the ranunculaceous groups in
Eurasia (including the Caucasus) in past periods;
possible migration into the Caucasus of some an-
cestral groups of this family from the east through
Asia Minor and some xerophytic groups from the
Mediterranean Region; evolution of some groups
within the Caucasian flora itse
According to the literature, a flora of the Ap-
palachian Province of the Atlantic North American
Region is ancient (mainly Tertiary), whereas the
1032
Annals of the
Missouri Botanical Garden
flora of the North American Prairies and the At-
lantic-Gulf Coastal Plain provinces are compara-
tively recent and derivative. Our data support this
conjecture, including close relationships of the bo-
real floras of Eurasia with those of North America
while, on the other hand, maintaining that there
were relatively prolonged disconnections of the flo-
ras in the western and eastern parts of both con-
tinents (31, 98, 184). These floristic events were
promoted by means of sea barriers (ancient Siberian
Sea and the Straits of Mexico) and Miocene and
more recent land bridges between Eurasia and North
America through the Pacific and Atlantic oceans
(135, 251).
Seventeen ranunculaceous genera are shared by
North American and Eurasian boreal floras. It is
remarkable that more than half of them (Caltha,
Actaea, Cimicifuga, Delphinium,
Clematis, Anemone, Pulsatilla, Ranunculus, and
Thalictrum) consist of sections with Eurasiatic—
North American distributions. Although species in
common to these floras are few (e.g., Anemone
Aconitum,
narcissiflora, Thalictrum alpinum, Ranunculus
pedatifidus), pairs of corresponding or closely re-
lated species are numerous (e.g., Actaea spicata-
A. rubra, Trautvetteria japonica-T. grandis,
Enemion raddeanum-E. biternatum).

Appalachian and Rocky Mountain provinces were
important centers of North American differentia-
tion of the Ranunculaceae. Within the former, the
Xanthorhiza, and Ane-

E
relict genera Hydrastis,
monella evolved, and within both of them, some
sections of Trollius, Aquilegia, Ranunculus, Tha-
lictrum, Enemion, and Cimicifuga. Possibly, the
two last-mentioned genera originated within these
floras. Compared with the peculiarities of distri-
bution of species of Hydrastis, Xanthorhiza, and
Anemonella (they occur disjunctively through about
ten states in the Appalachian province, e.g., Illinois,
Tennessee, Virginia, and others), we regard the
age of these genera (at least that of Enemion) as
more recent than the Eastern Asiatic endemic gen-
era (e.g., Beesia, Calathodes).
A comparison of the distribution of the Ranun-
culaceae in all four regions of the Boreal Subking-
dom (Eastern Asiatic, Circumboreal, Atlantic North
American, and Rocky Mountain) showed the con-
siderable floristic role of this family in each. These
data form the basis of our supposition that the
development of the Ranunculaceae took place over
a long period of time within the Tertiary warm-
temperate flora which was in common to all cir-
cumpolar territories of the Northern Hemisphere
(31, 296). We regard western and eastern parts
of eastern Asia and eastern North America (Ap-
palachians) as significant refugia of this ancient
flora. The Altai-Sayan id Alps, Carpathians,
Pyrenees, Caucasus, and t ocky Mountains
were, in our opinion, ee centers of the
differentiation of some groups of the Ranuncula-
eae.
In the Madrean Region of the Madrean Sub-
kingdom all ranunculaceous species are concen-
trated on mountain slopes, and they are mainly
members of the Californian and Mexican Highland
provinces. These species are scanty in chaparral
formations and absent in deserts. All genera of the
Ranunculaceae are in common to those in both
Eurasiatic and North American floras of the Boreal
Subkingdom, but species in common are few and
most of them are relict disjuncts. The mountains
of California were one of the secondary centers of
differentiation of Delphinium, and some groups of
Thalictrum evolved in the Mexican Highlands.
Our analysis of the Ranunculaceae within the
Madrean Region upholds the suspected (251, 286)
relationships of many northern Californian groups
of species with those in the boreal floras in both
western and eastern North America, and, more-
over, with those in boreal Eurasia. Stebbins &
Major (251) regarded Trautvetteria grandis, Del-
phinium californicum, Clematis occidentalis,
Anemone quinquefolia, and some other disjuncts
as relicts of Tertiary deciduous mesophytic forests,
although most endemic species of Delphinium have
a more recent age, and our data confirm that
hypothesis. It is remarkable that 15 genera of the
Ranunculaceae are in common to the floras in the
above-mentioned regions of the Boreal and Mad-
rean subkingdoms.
The modern flora of the regions of the Ancient
Mediterranean Subkingdom is rather xerophytic,
but the Ancient Mediterranean flora developed as
a derivative and mainly migratory one from boreal
and tropical mesophytic floras. Most of the Angio-
sperms in the Mediterranean flora are related to
corresponding Eastern Asiatic groups (Popov—
245).
Within the Mediterranean Region the floras of
the Liguro- Tyrrhenian and Iberian provinces are
quite rich with Ranunculaceae. They are similar
to the Balkanian flora of the Circumboreal Region
but much different from the rest of the Mediter-
ranean provincial floras. At the same time, the
flora of the East Mediterranean Province is related
to the most xerophytic provincial floras of the Ir-
ano-Turanian Region (e.g., Mesopotamian), and
within the former about half of the species of Ra-
nunculaceae are annuals.

Geographical Analysis of Ranunculaceae
Our analysis of the Ranunculaceae within the
Mediterranean floristic provinces showed their xe-
rophytic features (presence of many annuals and
bulb plants) and clear connections with mesophytic
groups of this family in the floras of the Boreal
Subkingdom, especially with those in the high-
mountain floras of Southern Europe.
Within the Irano-Turanian Region, most Ra-
nunculaceae belong to the provincial floras of the
Anterior Asiatic Subregion, while in the floras of
the Central Asiatic Subregion there are relatively
few Ranunculaceae. Most ranunculaceous repre-
sentatives are concentrated in the flora of the Ar-
meno-Iranian Province, which is surpassed world-
wide for the richness of the Ranunculaceae only
by the Sikang Yunnan Province. Nevertheless, the
number of endemic species is remarkably low, es-
pecially as compared with the flora of the Sikang
Yunnan Province (30/220 vs. 180/400—see Ta-
ble 1). Within Ranunculaceae predominate species
with boreal and nemoral affinities predominate in
the floras of eastern Asia and South Siberia. These
phenomena confirm the close connections between
the Armeno-Iranian, South Siberian, and Eastern
Asiatic floras and might reflect that the ancient
flora of Anterior Asia was once more mesophytic.
From an analysis of the role of the Ranuncu-
laceae in the provincial floras of the Irano-Turanian
Region, we note that the highlands of Middle Asia
(Pamiro-Alai, Tien Shan, and others) were sites of
secondary formation of some groups of this family
(more than 100 endemic species of Aconitum,
Delphinium, Aquilegia, Anemone, and Ranun-
culus). The floras of the Turkestanian, Dzungaro-
Tien Shan, and Central Tien Shan provinces are
very similar in terms of Ranunculaceae. This phe-
nomenon reflects the autochthonous development
of the Mountain Middle Asiatic flora on the base
of the ancient boreal groups of Angiosperms (Ka-
melin, 140, called them the Turkmenian and the
Himalayan-Mediterranean branches). According to
Pavlov (227) and Vykhodtsev (329), most of the
iddle Asiatic mountain endemics are recent (Qua-
ternary) and progressive, while Ovchinnikov (218)
claimed that within them are some relict elements
of nemoral complexes with certain Eastern Asiatic
relatives (e.g., disjuncts Trollius lilacinus, Del-
phinium brunonianum, Hepatica falconeri, Par-
opyrum anemonoides). We agree therefore wit
Kamelin (140) that the Mountain Middle Asiatic
flora, including the floras of the Tien Shan, is a
single unit.
The Armeno-Iranian and Central Anatolian pro-
vincial floras are similar to the flora of the Medi-
terranean Region and are much different from the
floras of Mountain Middle Asia
annuals (species of Consolida, Nigella, and oth-
. There are many
ers), but almost no endemic species of the Ranun-
culaceae. Species in common to the floras of Moun-
tain Middle Asia, Armeno-Iranian, and Central
Anatolian provinces are few, especially within 4c-
onitum, Delphinium, Aquilegia, Anemone, and
Pulsatilla. Meanwhile, the two last-mentioned flo-
ras include some genera and many species shared
with those in the Caucasian floras but absent in
both the Middle Asiatic and Mediterranean floras
(e.g., Caltha polypetala, Helleborus orientalis,
Actaea spicata, Isopyrum thalictroides). It is re-
markable that Caltha, Helleborus,
Isopyrum are boreal mesophytes with many species
in both the floras of the Eastern Asiatic and Cir-
cumboreal regions.
The floristic richness of the Ranunculaceae in
the floras of the Western Himalayan and North
Baluchistanian provinces is intermediate between
Actaea, and
the high-mountain floras of Middle and Eastern
Asia.
The Ranunculaceae in the Central Asiatic pro-
vincial floras, both Mongolian and Tibetan, consist
of few endemic species. The outlying northeastern
districts are related to those in the Altai-Sayanian
and West Chinese floras.
We conclude that the flora of the Ancient Med-
iterranean Subkingdom played a noteworthy role
in the differentiation of the Ranunculaceae largely
because of the evolution of annual (Vigella, Con-
solida, and Aconitella) and bulb plants (species of

Annals
Sora ES Garden
The Indo-Malesian Subkingdom is regarded as
the greatest refugium of the Palaeotropical Angio-
sperms in which were preserved many endemic
and relict families and genera (10, 296, 337).
There are few ranunculaceous representatives, and
they occur mainly in the mountain flora of this
subkingdom. Lam (177) and van Steenis (287)
regarded Anemone, Ranunculus, and Thalictrum
as examples of temperate genera that penetrated
the Malesian tropical mountain flora from temper-
ate eastern Asia through ancient mountain ridges.
Our data do not challenge this idea. Possibly, the
Ranunculaceae migrated through Malesia in the
Southern Hemisphere by two different routes. The
western route went through Sumatra, Kalimantan,
and Java, and the eastern one passed through the
Philippines, Molucca, Sulavesi, and New Guinea.
Van Steenis (288) and Aubreville (9) supposed
these groups of islands to be the distinct centers
of development and dispersal of the Angiosperms:
the former island group was related to the South-
eastern Asiatic floristic center, while the latter group
was home to part of the Australo-Papuan flora.
The formation of uplands in New Guinea in the
Late Oligocene limited north-to-south penetration
by high-mountain Ranunculaceae (201, 202, 248).
After that time some endemic groups of Clematis
and Ranunculus evolved in the highlands of Ma-
lesia. Areas of some species (e.g., Naravelia da-
syneura, Anemone sumatrana, Clematis leche-
naultiana) occur in the adjacent Indo-Chinese,
Malesian, and Indian regions, while some other
species (e.g., Anemone vitifolia, Clematis mey-
eniana) occur disjunctively also in the highlands
of West China, the Himalayas, and Japan. The
most interesting area has Clematis pickeringii be-
cause it includes Malesia, New Caledonia, and
northeastern Australia.
n the flora of the African Subkingdom only two
genera are restricted to Africa and Madagascar:
Clematopsis, which is related to Clematis, and
The
rest of the ranunculaceous genera (Anemone,
Clematis, Delphinium, Nigella, Ranunculus, and
Thalictrum) are shared by the floras of the Boreal
and Ancient Mediterranean subkingdoms, and many
species of them are related to the species of the
Knowltonia, which is related to Anemone.

sonit is distributed in the alpine and subalpine belts
of Mount Kilimanjaro and a related species, 4.
glaucifolia, grows in high mountains of western
China. Clematis grata and Delphinium dasycau-
lon are common to the floras of western China,
the Himalayas, and in Hindustan.
Our analysis of the distribution of the Ranun-
culaceae in Africa confirms Hedberg's (117, 118)
and Boughey's (27) suggested existence of the An-
cient Tropical Mountain flora in Africa and the
possible connections between the Afro-Alpine and
Boreal floras of Africa and Eurasia in past periods.
We suppose that the ranunculaceous representa-
tives migrated into Africa from Eurasia by means
of some ancient land bridges (e.g., Sunda, Arabian)
that existed there until the Late Cretaceous and
early Quaternary (246, 250, 335). Afterwards,
formation of the mountain ridges in eastern Africa
(dated as Miocene) promoted development of the
high-mountain groups of Ranunculaceae and mi-
gration of some of them into South Africa, where
cold and temperate conditions existed until the
Cretaceous (53). Few groups (e.g., species of Clem-
atis, Clematopsis, and Knowltonia) migrated
southward and secondarily became adapted to the
tropical conditions of Africa

Summing the data of the analysis of the Ra-
nunculaceae in the floras of the Neotropical King-
dom, we must keep in mind that North America
was separated from South America with a relatively
wide sea space during Cretaceous and Paleogene
time (250). On the other hand, until the Oligocene
South America was joined through the subantarctic
bridge with Antarctica which at that time was cov-
ered with cool temperate forests (246, 248). The
Andes were formed in the Pleistocene and after
that they became an important transtropical bridge
for the migration of temperate floristic elements
from North America to South America and vice
versa (211,
Species of Thalictrum and Anemone multifida

The Andean high-mountain flora was one of the
important centers of ranunculaceous differentia-
tion. There are two distinct monotypic endemic
genera in this flora, Oreithales and Laccopetalum.
The former is hexaploid and seems to be derived
from Anemone (32, 68); the latter differs from
other Ranunculaceae by possessing a large number
of nectary glands and possessing large unbroken
leaves (length over 40 cm)

Our analysis showed that within the Holantarctic

ancestors. Fisher (80) noted the predominance of
polyploids within the New Zealand species of Ra-
nunculus and listed 10 pairs of alpine species with
one member in New Zealand and the other member
a similar South American species (e.g., R. haastii—
R. semiverticillatus and R. nivicolus- R. capra-
rum). Consequently, Fisher supposed that high-
elevation New Zealand Ranunculus was derived
from the South American one, not from Malesian
species.
Mountain ridges in New Zealand formed in the
Late Pliocene (248), along with the rise of the
mountains in Australia and New Guinea. According
to Raven (248) and Wardle (334) the initial species
of Anemone, Clematis, and Ranunculus arrived
in New Zealand from South America in the Late
Pliocene or later, while species of Caltha already
spread there in the Paleogene.

Central Australian regions.
East Australian Region
Location: Queensland, New South Wales, Vic-
toria, and Tasmania.
Characteristic vegetation: high-mountain for-
est and ericoid formations.
Ranunculaceae: 5 genera, about 45 species
(24, 37, ).
Related pow Neozeylandic (2/5, e.g., Clem-
atis foetida, Ranunculus rivularis) and Chile-Pa-
tagonian (2/3, e.g., Ranunculus acaulis, R. bi-
ternatus).
Observations: about 30 endemic species (e.g.,
Anemone crassifolia, Caltha introloba, Clematis
aristata, C. gentianoides, Ranunculus gunni-
anus), and most of them are endemics of Tasmania
only (e.g., Ranunculus muelleri, R. scapigeri).
Southwest Australian Region
Location: southwestern Australia.
Characteristic vegetation: dry and rainy scler-
ophyllous forests of Casuarina and Eucalyptus,
also scrub.
Ranunculaceae: 2 genera,
Clematis microphylla, Ranunculus lappaceus).
Central Australian Region
Location: North Territory, Great Sandy Desert,
Victoria and Gibson deserts, and other areas.
9 species (e.g.,
Characteristic vegetation: tropical desert and
dry savanna formations.
Ranunculaceae: absent.
The Ranunculaceae in Australia are related to
those in the Holantarctic floras. Thus, Caltha in-
troloba, like other species of Caltha in the South-
ern Hemisphere, belongs to sect. Psychrophila;
Anemone crassifolia belongs to sect. Rivularid-
ium; and Australian species of Ranunculus are
related to South American species. Our conclusion
is similar to that of Raven (248) who supposed that
most high-mountain plants, including species of
Anemone and Ranunculus, migrated to Australia
and New Zealand from South America in the Late
Pliocene or later. Raven suggested that a northern
migratory route for plants into Australia through
alesia was geologically impossible because the
alpine flora of New Guinea is younger than t
Australian one (334). Moreover, Melville (201)
included the Ranunculaceae with a group of five
families that invaded in Australia from the north.
CONCLUSIONS
The peculiarities of the role of the Ranuncula-
ceae in the floras of regions and provinces world-
wide reflect the peculiarities of origin, differentia-
tion, and distribution of this family, including the
relationships of tropical, temperate, mountain, and
lowland floras, and including the relationships of
the floras of the Northern and Southern hemi-
spheres.
According to paleobotanical literature (22, 60—
63, 93, 253-255), there are no fossil remnants
of the Ranunculaceae in the Cretaceous. The ear-
liest such fossils, fruits of some species of Clematis
and Ranunculus, are Oligocene and come from
Eurasia (e.g., England, Ukraine, the Urals). Ra-
nunculaceae are represented in Miocene deposits
by remnants of few species of Clematis, Ranun-
culus, and Thalictrum. Pliocene ranunculaceous
remnants belong to Aquilegia, Anemone, Clema-
is, Ranunculus, and Thalictrum, about 40 tem-
perate species altogether. They were found in many
places within the vast territories of Eurasia, North
America, and South America.
These paleobotanical phenomena reflect the
considerable differentiation of the Ranunculaceae
and their radiation throughout the world durin
the Neogene. The sharp increase of the develop-
ment and dispersion of the Ranunculaceae was
associated with the Upper Eocene general fall of
temperature and replacement of tropical and sub-
tropical floras with temperate ones across Eurasia
and North America (78, 229, 307).

Annals of the
Missouri Botanical Garden
There are two different opinions about the origin
of the Ranunculaceae. Scharfetter (263) placed
the origin within the Early Tertiary tropical flora,
while Popov (235) claimed that the Ranunculaceae
originated within the Neogene warm-temperate flora
of Eurasia, similar to 50 other derivative angio-
spermous familie
e P with both these propositions and
claim an Early aceous origin and differentiation
of the Ranunculaceae. This is based partly on the
peculiarities of the disjunctive areas of such genera
as Caltha, Anemone, Clematis, Ranunculus, and
Thalictrum. The origin and primary differentiation
of the family must have taken place after the
breakup of the supercontinent Pangaea (or one like
it). Our data are consistent with the horizontal drift
of the continents (138, 201, 250, and others).
Development of the distinctive Holarctic and
Holantarctic groups of Caltha (sects. Caltha and
Psychrophila) occurred in temperate parts of
Gondwana and Eurasia and seems likely to reflect
the Middle Cretaceous differentiation of the north-
ern and southern temperate floras. In this point we
agree with Tolmachev (310) and Moore (211) who
considered Caltha as one of the most ancient tem-
perate Angiosperm genera
The above-mentioned Anemone, Clematis, Ra-
nunculus, and Thalictrum are temperate genera
that occur fairly continuously throughout the mon-
tane Palaeotropics and Neotropics and suggest the
routes by which their migrations could have taken
place. Notably, Anemone rivularis and Clematis
ranunculoides with archaic morphological features
are tropical-mountain forest elements of the flora
of Southeastern Asia. Boughey (27) regarded the
mountain forest flora in Africa and Asia as very
old and maintained that its survival to the present
as an insular flora scattered discontinuously over
huge land masses implies a connection with con-
tinental drift, land-bridges, and long periods of time.
Our analysis showed that the majority of species
of all genera occur in mountains and that, more-
over, species of more than half of the genera,
including all endemics, are restricted chiefly to
mountain locations. Moreover, the most numerous
groups of species of large genera such as Aconitum,
Delphinium, Anemone, Clematis, Ranunculus,
and Thalictrum are distributed mainly in moun-
tains. Our data confirm Rau (243) who considered
the Ranunculaceae to be an important member of
the high-mountain ecosystems and is the basis for
supposing its origin in mountain locations.
Within temperate montane floras of the tem-
perate regions the Ranunculaceae take fourth to
seventh place, while in tropical montane habitats,
the Ranunculaceae fall to 15th-17th place (70,
140)
Comparison of the ranunculaceous representa-
tives in the modern floras of the Northern and
Southern hemispheres (the former contains 51 gen-
era and about 2,200 species of all 14 tribes, the
latter is home to 11 genera and about 250 species
of 5 tribes) and comparison of their endemic genera
(17 genera of 10 tribes vs. 4 genera of 2 tribes,
respectively) indicates that primary differentiation
of the Ranunculaceae took place in the Northern
Hemisphere.
From our geographical analysis together with
data on comparative morphology, we propose that
the ancestors of the tribes Cimicifugeae, Anemo-
neae, Clematideae, Aquilegieae, Asteropyreae, and
Kingdonieae initially developed within the ancient
floras of eastern Asia, while the tribes Coptideae
(at least Xanthorhiza) and Hydrastideae were
formed in North America. It was impossible to
dide the place of the development of the ances-
s of the tribes Trollieae, Helleboreae, Delphi-
nieae, Isopyreae, Ranunculeae, and Thalictreae,
because some of their genera (e.g., Beesia, Cal-
athodes, Trollius, Aconitum, Eranthis, Aquilegia,
Semiaquilegia, Urophysa, and Dichocarpum)
originated in eastern Asia, while other genera (e.g.,
Helleborus, Nigella, Consolida, Leptopyrum, and
Aconitella) differentiated in the Ancient Mediter-
ranean Subkingdom or North America (Enemion
and Anemonella). Some associated in their origin
and distribution with the temperate palearctic flora
Adonis, Trautvet-
teria, Isopyrum, Paraquilegia, and Paropyrum).
(Delphinium, Callianthemum,
In conclusion, we regard the Ranunculaceae as
an ancient temperate family that originated in Cre-
taceous time within montane temperate floras of
the Northern Hemisphere.

A REVISION OF THE James S. Miller:
NEW WORLD SPECIES OF
EHRETIA (BORAGINACEAE)
ABSTRACT
Ehretia is a pantropic M genus of about 50 species with centers of diversity in eastern Africa and tropical Asia.
Although as many as 12 species of Ehretia have been recognized in the New World, field and herbarium studies
suggest that the patterns of variation in the New World i
recognized Ehretia anacua and E. tinifolia as distinct ed and have distinguished several species with serrate
leaf margins. Field studies suggest that characters used to differentiate species with serrate leaf margins often var
y
within populations or on a single individual. Thus Ehretia latifolia i is treated in a broad sense, including all segregate
leaves.
species with serrate
The largest genus of the subfamily Ehretioideae,
Ehretia, contains about 50 species (Airy-Shaw
»
1973) distributed tropically and subtropically in
both hemispheres. The genus is primarily Old World
in distribution with more species in Africa than in
Asia; Baker & Wright (1905) recognized 23 Af-
rican species, mostly in eastern Africa, Johnston
(1951) recognized 12 species in eastern Asia, and
perhaps several more occur in the Malay archi-
pelago and Australia. The genus is poorly repre-
sented in the New World where it ranges from
The
last complete treatment of the New World species
was that of Miers (1869) who recognized eight
species. An additional six species were published
by various authors after his work. Standley (1924)
recognized seven species in Mexico and one more
in Costa Rica (Standley, 1938) based on relatively
few collections of the species with serrate leaf mar-
gins. With the great increase of collections avail-
Texas to Panama and the Greater Antilles.
able since Standley's work, initial studies suggested
that the characters he used to separate the species
were of questionable validity, and delimitation of
the species became problematic. The present re-
vision combines a study of herbarium specimens
with extensive field study of the variation of leaf
and indument characters to resolve these problems.
The work is supplemented with surveys of leaf
architecture and pollen morphology throughout the
Ehretioideae to be published later; only results di-
rectly relevant to the New World species of Ehretia
are included
n addition 1 to o problems with delimitation of
species of Ehretia in the New World, there have
been questions regarding definition of the genus.
An additional aspect of this study was an exami-
nation of generic limits in the arborescent genera
of Ehretioideae. Selected species of Bourreria,
Carmona, Rochefortia, Rotula, and Old World
species of Ehretia were examined.

Civil and Natural History of Jamaica. Linnaeus
(1759) later validated the genus with the binomial
Ehretia tinifolia. De Candolle (1845) significantly
enlarged the concept of the genus by treating 58
species, many of which are now referred to the
segregate genera Bourreria, Carmona, Rochefor-
tia, and Rotula. De Candolle recognized four sec-
tions within Ehretia. All of the species of his sect.
Ehretia are still referred to the genus but his sect.
Bourreria was a diverse group of species now as-
signed to Bourreria and Ehretia. The two species
that he treated in sect. Carmona have been con-
sidered conspecific and treated as Carmona retusa
(Vahl) Masamune (Thulin, 1987). His fourth sec-
tion, sect. Xeroderma, was another diverse group
containing species now distributed in Bourreria,
Ehretia, Rochefortia, and Rotula. Several species
of sects. Bourreria and Xeroderma have since
been excluded from Boraginaceae (see excluded
species).
John Miers published a series of papers on the
Boraginaceae shortly after De Candolle's work and
treated Ehretia (Miers, 1869) in a more restricted
se. Miers segregated the genus Rotula (as
Rhabdia) and allied it with Khretia and Cortesia
(a small genus endemic to saline areas in northern
Argentina). Miers also sorted the species that most
recent authors have included in Bourreria into
Bourreria and Crematomia. Crematomia was
characterized by having fruits with four pyrenes,
each retaining an apical attachment to the stigma
at maturity. Recent authors (Schulz, 1911; No-
wicke, 1969; Gibson, 1970; Miller, 1988) have
not accepted this as sufficient for generic recog-
nition and have included these "Crematomia"
species in Bourreria. Miers pointed out that Bour-
reria was distinct in its fleshy calyx with five mar-
ginally tomentose, valvate lobes; fleshy, rotate co-
rollas; and fruits that at maturity divide into four
angular Lied each with a ridged endocarp and
spongiase mesoc
Bentham & Hooker (1876) recognized three
sections e Ehretia, one of which, Carmona, has
been treated as a segregate genus by most recent
authors (Johnston, 1951; Nowicke & Miller, in
press). Johnston (1951) recognized their other two
sections, Kuehretia and Bourrerioides, in his treat-
ment of the eastern Asian species. Although John-
ston devoted most of his research career to Bo-
raginaceae, he published little on Ehretia or
Bourreria. He did recognize Carmona and Rotula
as distinct from Ehretia (Johnston, 1951). In his
treatment of the Boraginaceae of the southern West
Indies (Johnston, 1949) he also considered Bour-
reria and Rochefortia as distinct from Ehretia.
Hence, although Johnston never treated Ehretia,
it appears that his generic concept was similar to
that of most recent authors
As currently defined, ilie Ehretioideae consist
of eleven genera that segregate into four probably
monophyletic groups, but the relationships among
them remain obscure. Richardson (1976, 1977)
separated Tiquilia from Coldenia and these two
genera of prostrate plants with dry nutlets form a
distinct lineage within the Ehretioideae. Lepido-
cordia, including Antrophora (Miller & Nowicke,
in prep.), is also quite distinct from any of the other
genera of the Ehretioideae, and Johnston (1950)
considered the genus intermediate between the Eh-
The Argentinian
endemic Cortesia and the Australian endemic Hal-
retioideae and Heliotropioideae.
gania comprise a questionable third group of
shrubby plants of xeric regions with often trifid or
unevenly toothed sclerophyllous leaves. Whether
these two genera are closely related or simply share
a similar appearance because of convergence in
similar habitats is unclear. Halgania is unique in
the Ehretioideae in its stamens connate around the
style.
The remaining genera of Ehretioideae, Bour-
reria, Carmona, Ehretia, Pteleocarpa, Rochefor-
tia, and Rotula, seem to form a rather close group.
Of these only Pteleocarpa seems to stand apart in
its unusual winged fruits. Although recent pollen
studies (Nowicke & Miller, in prep.) supported
recognition of Bourreria, Carmona, Rochefortia,
and Rotula as distinct
appear closely related and form a distinct group
within the subfamily. (See Table 1 for comparison.)
Thulin (1987) transferred five African species
of Ehretia to Bourreria, a genus previously con-
sidered to be restricted to the Neotropics. These
species seem to form a monophyletic group distinct
rom Ehretia, they still
from Ehretia in their valvate calyces, campanulate
to urceolate corollas, and ridged endocarps. Eh-
retia is a more natural genus without these species,
but they are probably distantly related to the New
World species of Bourreria, which are character-
ized by rotate corollas and pollen grains with thick-
ened ridges on each side of the colpi (Nowicke &
Miller, unpublished). The characteristics of the
genera closely allied to Ehretia are compared in
Table 1 and a key to the genera of the Ehretioideae
is provided below. Although Johnston (1935) in
cluded Saccellium in the Ehretioideae, recent pol-
len studies (Nowicke & Miller, in prep.) indicate
that it is more closely related to the genera of the
Cordioideae where Tahktajan (1987) placed it.

THE New WORLD SPECIES OF ÉHRETIA
Only three of the New World species that De-
Candolle (1845) included in Ehretia still belong to
the genus. These are Ehretia anacua (Teran &
Berl.) I. M. Johnston (as E. elliptica DC.), E.
latifolia DC., and E. tinifolia L. Miers (1869)
adopted a very narrow species concept, recognizing
seven species with entire leaf margins, where only
two have been recognized by recent authors (Stand-
ley, 1924; Nash & Moreno, 1981). Various au-
thors described six New World species of Ehretia
with serrate leaves between 1891 and 1938. Stand-
ley (1924) recognized five species with serrate
leaves in Mexico and an additional one from Costa
Rica (Standley, 1938). They differed in leaf shape
and indument, although field studies reveal these
characters are extremely variable. The present
study recognizes three species of Ehretia in the
World. This differs from recent treatm
by grouping all populations with distinctly serrate
leaf margins as a single, variable species. This
variation in leaf morphology of Ehretia latifolia
is discussed in detail under that species.

Almost everyone questioned in Mexico had a

Ehretia and because of this no common names are
reported in this study.
MORPHOLOGY
HABIT
All species of Ehretia are trees or shrubs (Fig.
1). Although New World species are trees, E. an-
acua is frequently multistemmed. Habit is much
more variable among the O orld species, which
range from trees, like E. acuminata fad
desert shrubs, such as E. rigida (Thunb.) Druce.
The genus Rotula differs from Ehretia in its arch-
ing, flexuous branches associated with its rheophy-
tic habitat. The trunk of Æ. latifolia is usually
uted, at least on mature plants (Fig. 2
LEAVES
All species of Ehretia have simple, alternate,
nearly lanceolate to nearly round leaves. A few
Old World species are extreme, for example Eh-
retia saligna R. Br. of Australia has elongate,
straplike leaves. Leaf shape is variable within
species, a single individual often showing a signif-
icant diversity of leaf shapes on a single branch
(see E. latifolia).
Ehretia tinifolia and E. anacua have entire-

rown. e trees are often left as sh
margined leaves. In some specimens of Ehretia
anacua, however, a few leaves exhibit short teeth
along the margin. Ehretia latifolia is unique among
the New World species in its evenly serrate leaf
margins. Only rarely are the teeth short and un-
even.
Leaf architecture can be valuable in delimitation
of higher taxa (Hickey & Wolfe, 1975; Lorence,
1985; Levin, 1986a, b, c) and has been used within
77). Leaves of 36
species of 10 genera of i dada d
for leaf architectural features. Eleven species of
Ehretia were selected, including the three New
World species. Leaves were removed from her-
barium collections, cleared, stained, and mounted
according to methods of Dilcher (1974), and ar-
chitectural features were analyzed following the
system of Hickey (1973, 1977, 1979). A complete
survey of the genera of the Ehretioideae will be
genera (Rury & Dickison, 1
published separately, but results are reported here
for the New World species of Ehretia and several
other taxa for comparison. Voucher specimens for
the leaves examined are cited in the figure captions.
Leaves of Ehretia appear to be primitively bro-
chidodromous, this being the condition in nearly
all of the species, and in the closely related genera
Bourreria, Rochefortia, and Rotula. Craspedod-
romous venation is restricted to the few species
with serrate leaf margins. Of the New World species,
E. tinifolia has brochidodromous venation (Fig. 4).
Ehretia latifolia is the only New World species
consistently with craspedodromous venation (Fig.
3). Although this might appear to be a conservative
character, it is variable in E. anacua, which gen-
bit of Ehretia latifolia. —1. Tree 8 m tall,

occasional individuals and leaves on juvenile shoots
ave serrate margins and semicraspedodromous
venation (Fig. 6). Even in E. acuminata, an
World species with serrate leaves (Fig. 5), leaves
are brochidodromous with veins that arise second-
arily from outer loops beyond the secondaries and
extend into the teeth.
The patterns of tertiary and higher-order ve-
nation vary only slightly among the species of Eh-
retia. Generally, five or six orders are visible in
most species. Ehretia anacua (Fig. 8) and E. tin-
ifolia have randomly reticulate tertiary veins that
anastomose and form a weak, composite interse-
condary vein. The higher orders of venation vary
from random to orthogonal reticulate. The ultimate
marginal venation is looped in both of these species.
Ehretia latifolia (Fig. 9) and E. acuminata (Fig.
10) have randomly reticulate to weakly percurrent
tertiary veins. Intersecondary veins are weak and
restricted to the apical portion of the leaf, or are
completely absent. Ultimate marginal venation is
incomplete in E. latifolia but looped in E. acu-
minata
The New World species of Ehretia are essen-
tially evergreen. Ehretia anacua is partly decid-
uous only at the northern extreme of its range in
Texas. Ehretia latifolia appears to produce most
of its leaves during the onset of spring rains and
hold them for about two years. Only in the pop-
ulation near Monte Alban, Oaxaca, in Mexico did
ed all of its
leaves during the dry season. New leaves were
emerging even as the last few old leaves dropped.

Standley (1924) differentiated New World
species of Ehretia using density and thickness of
hairs and presence or absence of glandular hairs.
Field observations indicate that neither of these are
significant in the sense that Standley used them.
The widely scattered geographic pattern of plants
with glandular hairs is not indicative of a mono-
phyletic group, but rather probably a character
that is expressed only rarely.
Collections of Ehretia anacua and E. latifolia
show considerable variability in leaf indument, much
of which can be explained as a temporal phenom-
enon. Young leaves of E. latifolia are densely and
softly pubescent. Expansion of the leaf blade de-
creases the density of hairs, and young, fully ex-
panded leaves are less densely pubescent with long-
shafted, simple hairs from a multiple-celled, basal
cystolith. During the life of an individual leaf, the
majority of the brittle shafts of the hairs are often
broken off and the leaf may appear nearly glabrous
cence, the cells of the basal cystolith continue to
expand and harden. The basal cystoliths with the
remaining portions of the hair shafts often make
up what appears to be a scabrous indument. Thus
an individual leaf may pass through stages from
velutinous, to sparsely pubescent, to nearly gla-
brous, and finally to scabrous. e southern
portion of the range of Ehretia latifolia the dry
season is less severe. Here leaves are somewhat
larger, and seldom do herbarium collections contain
eaves old enough to have reached the last, seem-
ingly scabrous, stage. These field observations sug-
gest that indument is not a reliable character for
the delimitation of segregate species from £. la-
tifolia.
INFLORESCENCES
All species of Ehretia have many-flowered in-
florescences that are cymose or are paniculate with
the individual branches of the panicles cymose.

The inflorescences of Ehretia tinifolia and E. la-
tifolia have a distinct central rachis and are ba-
sically paniculate with cymose individual branches.
Ehretia anacua has a short-pedunculate, cymose
inflorescence without a central leader. This type
of cymose inflorescence is widespread in the Eh-
retioideae and Cordioideae and is probably the
primitive character state in the two subfamilies.
FLOWERS
The floral morphologies of the New World species
of Ehretia are quite similar. Ehretia anacua has
hairs on the corolla that are not present in F.
latifolia or E. tinifolia, but other differences are
small. Floral features that vary among the New

calyx and size, color, and form of the corolla.
The diversity of breeding systems in the Borag-
inaceae is well documented (Bawa & Beach, 1981;
Ganders, 1979; Vuilleumier, 1967) and second
only to Rubiaceae in the number of distylous species.
Ehretia has monomorphic, bisexual flowers with
the stamens exserted and exceeding the style. This
is the most common breeding system in the Eh-
retioideae; the only genera that differ are Lepi-
docordia (Miller & Nowicke, in prep.) and Ro-
chefortia (Lefor, 1968), both dioecious. Corollas
are small and white in the New World species and
are visited by a wide variety of small generalistic
Diptera, Hymenoptera, and Lepidoptera. The plants
| observed of Ehretia latifolia were visited by
many small insects, mostly dipterans.

icke & Ridgway, 1973; Nowicke & Skvarla, 1974;
Nowicke & Miller, in press). Pollen of Ehretia is
more or less prolate and three-colporate (Nowicke
& Miller, in prep.). Three pseudocolpi or pseu-
docolpoid depressions alternate with the colpi. The
apertures have elongate colpi with a bridge of ek-
texine over the endoaperture. The tectum is more
or less complete and faintly rugulose, slightly gran-
ular, or psilate.
Ehretia is homogeneous and distinct from other
genera of the Ehretioideae in its pollen morphology
(Nowicke & Miller, in prep.). Evidence from pollen
does not support earlier sectional divisions of the
genus (see Bentham & Hooker, 1876; Johnston,
FRUITS
The fruits of Ehretia are drupaceous with a thin
to leathery exocarp, fleshy to mucilaginous me-
socarp, and bony endocarp. They vary from white,
as in E. latifolia, through yellow and orange, as
in E. anacua, to red, as in E. longiflora Champ.
(Johnston, 1951). The calyx generally persists ba-
sally but is not at all accrescent. Although the
stigma is usually lost, the base of the style often
persists at the apex of fruits.
Fruit morphology has been important for generic
delimitation in the Ehretioideae. Bourreria, Car-
mona, Ehretia, Rochefortia, and Rotula have es-
sentially drupaceous fruits, varying in the texture
of the mesocarp, number of parts into which the
endocarp divides at maturity, and surface sculp-
turing of the endocarp. The mesocarp of these
genera except for Bourreria is fleshy to mucilag-
inous. That of Bourreria is spongiose, being fleshy
only when fruits are immature, becoming somewhat
fibrous with large open air pockets.
The structure of endocarps was examined by

removing mature fruits from herbarium specimens,
soaking in 5% NaOH for 1-5 days to soften the
exocarp and mesocarp, washing in running water
until clear of all outer material, and then drying.
They were then examined with an Hitachi 5450
scanning electron microscope. Fruits of 54 species
of ten genera of Ehretioideae were examined. Col-
denia and Tiquilia stand apart in having fruits of
four dry nutlets. The fruits of Halgania, Lepi-
docordia, and Rotula all differ in having a thin-
walled endocarp. Bourreria, Carmona, Ehretia,
and Rochefortia, however, all have somewhat sim-
ilar fruits.
Fruits of Ehretia vary in the number of parts
into which the endocarp divides. Of the species
examined, Ehretia latifolia is the only species whose
endocarp remains entire at maturity. Ehretia ac-
uminata, E. anacua, E. dicksonii, and E. tinifolia
have fruits with two separate two-seeded pyrenes
at maturity. Ehretia amoena, E. coerula, E. cy-
mosa, E. laevis, E. obtusifolia, and E. rigida have
fruits with four separate single-seeded pyrenes. Of
related genera, Carmona has an endocarp that
remains entire. Rotula has a two-parted endocarp
and Bourreria and Rochefortia have four-parted
endocarps.
The surfaces of the endocarps of Khretia species
have distinct sculptural patterns. Two major types
occur in Khretia, and several others turn up in
related genera. Verrucose endocarps are found in
Ehretia acuminata (Fig. 15), E. dicksonit, E. la-
tifolia (Fig. 13), and F. tinifolia (Fig. 12). Ehretia
dicksonii is unusual among these species in having
an evenly puberulent endocarp with numerous short
hairs on the outer surface. Areolate endocarps,
with angular depressed areas, characterize most of
the Old World species with four-parted endocarps,
including E. rigida (Fig. 14). Ehretia anacua, of
the New World (Fig. 11), also has an areolate
endocarp but differs in being less regularly areolate
and in ano dividing into two parts at maturity.
Th of the most closely related genera
re
are quite different in sculpturing pattern. Carmona
retusa has an entire endocarp with few, low, broad
ridges but is otherwise nearly smooth (Fig. 16).
Rochefortia has endocarps with broad, thick,
rounded ridges as exemplified by R. spinosa (Jacq.)
Urb. (Fig. 19
varying from erect, as in
Fig. 18), to ee as in B. nemoralis (Gurke)
Thulin (Fig. 17).
Fruit structure suggests that KAretia consists of
o
two groups. One has one- or two-parted endocarps
with a verrucose surface and is found in the New
World and Asia. The second has four-parted en-
docarps with an areolate surface and is widespread
in the Old World. Ehretia anacua is the only New
World species in the latter group but differs in
having a two-parted endocarp.

Distribution. | Ehretia anacua occurs in
southern Texas and northeastern Mexico from sea
level to 1,300(-2,200) m in dry forests (Fig. 20).
Collections from Guanajuato, Oaxaca, and Que-
retaro are outside the natural range of the species
and are not included in the distribution map.
This common species was known as Ehretia
elliptica DC. until Johnston (1924) discovered the
older epithet published in Gaza Terán & Berlan-
dier. The description of E. scabra indicates that it
is synonymous although the brief citation of “cres-
cit in Mexico" does not indicate a type collection.
The names F. ciliata and E. exasperata are clearly
synonymous; E. ciliata differs from E. anacua in
no discernible characters, and the type of E. ex-
asperata is merely a juvenile shoot with serrate-
margined leaves. Likewise, the type of E. lancifolia
does not differ significantly in any character from
E. anacua. Although most type material for the
names lacks adequate locality information, it seems
likely that all were collected in northeastern Mexico
or Texas, a region in which no other species of
Ehretia occur.
n addition to its distinct geographic range, £.
anacua is easily distinguished from the other New
World species of Ehretia by its scabrous upper
leaf surface, cymose inflorescence, strigillose co-
rola tube, and usually entire leaf margins. It is
quite distinct in the genus with no apparent close
relatives.
Ehretia anacua is valued for its showy flowering
display and its shade. The specific epithet is derived
from the common name “anacua” (Nuevo León,

m (Fig. 21).
Ehretia latifolia exhibits extreme variability in
leaf shape and indument, which has bred confusion.
Standley (1924, 1938) recognized six species with
serrate leaves in the New World. With the excep-
tion of E. tehuacana, all were based on characters
of leaf shape and indument. When Watson (1891)
published E. mexicana, he made no mention of
how it differed from Æ. latifolia. The types of the
two are nearly identical, and Standley (1924) re-
duced E. mexicana to synonymy. Smith (1893)
published E. luxiana based on a collection from
Guatemala with broader leaves that was almost
glabrous abaxially and supposedly had larger flow-
ers. The populations from the southern portion of
the range do have slightly broader leaves that more
often tend toward abaxial glabrousness, but there
are many exceptions and there is no clear geo-
graphic discontinuity. At the time that Robinson
(1894) published E. cordifolia it appeared distinct
in having cordate leaf bases. However, field studies
(discussed below) indicate that this is not a valid
character since it varies on single individuals as
well as within populations.
The problem with Ehretia viscosa, a species
supposedly distinct in having glandular hairs, is
slightly more complex. The few collections of it
differ only in the possession of glandular hairs and
in all other respects are identical to E. latifolia.
Further, they come from localities scattered
throughout the Mexican range of FE. latifolia. Glan-
dular hairs thus appear to be an infrequently ex-
pressed trait rather than a monophyletic group that
should be recognized as a species.
Standley (1924) differentiated Ehretia tehua-
cana by its corollas about 10 mm long (supposedly
more than 3 mm longer than the other species he
recognized). None of the corollas on the type col-
lection exceed 6 mm (Standley must have based
his distinction on Greenman's original description)
and are within the normal range of variation for
E. latifolia. At the time that Standley (1938) de-
scribed E. austinsmithii, it appeared to be geo-
graphically disjunct with the nearest population to
the north in Guatemala. As currently defined, F.
latifolia has a relatively continuous distribution in
Central America, being unknown only in Honduras.
The Central American populations are quite uni-

FIELD STUDIES OF VARIATION OF
LEAF MORPHOLOGY
The numerous synonyms of Ehretia latifolia
seem to have arisen via a paucity of collections
and a failure to understand how leaf shape an
indument vary on individual plants, within popu-
lations, and between populations. Herbarium spec-
imens are only limited samples of individual trees
and seldom provide an adequate representation of
variation of leaf morphology. In order to assess
how leaf morphology varied on a single individual,
within populations, between populations, and over
the developmental life span of individual leaves,
collections were made over the range of F. latifolia
in Mexico.
ome variation emerges during the ontogeny of
an individual leaf (discussed earlier under leaf mor-
phology) and a small portion correlates with ge-
ography, but most variation appears random and
often can be found within a single population.
Two characters seem to vary geographically.
Plants from Central America and part of adjacent
Chiapas tend toward slightly broad, abaxially nearly
glabrous leaves, while plants from populations fur-
ther north have narrower, abaxially pubescent
leaves. other collections from Central
America have leaves puberulent below, and such
However,
leaves are found over a long geographic distance

pronounced dry season than occurs to the north
in parts of Mexico. In Cordia curassavica much
of the variation disappears in plants raised in the
greenhouse (Miller, 1985).
he second geographically correlated variation
is that plants from the Tehuacán Valley in Puebla,
Mexico, have leaves with smaller than usual ser-
rations on the margin. This extreme of variation
is not even consistent within Puebla and is not
considered worthy of taxonomic recognition.
Most variation in leaf morphology appears ran-
dom, varying in form and indument on individuals
and within populations. Five leaves from five in-
dividuals (in some cases five individuals could not
e found) in each population from various parts of
the distributional range in Mexico were measured
for length, width, length / width ratio, broadest point
(calculated as distance from broadest point of the
leaf to the base divided by total leaf length), apical
angle, and basal angle (Tables 3, 4). In addition
the indument on the adaxial and abaxial leaf sur-
faces was noted. The leaves selected were at least
three nodes below the apex of the shoot to avoid
immature leaves and never adjacent to a branch,
as these are often quite different in form.
Field studies reveal considerable variation in leaf
shape on a single tree, with leaf bases often varying
from acute to obtuse and sometimes even cordate

from one branch to another. Shape of the leaf base
was the character used to distinguish Ehretia cor-
difolia, but examination of leaves from different
branches of a single tree collected near Guelatao,
Oaxaco, Mexico (Fig. 22) shows this character to
vary on a single individual. The same type of vari-
ation in shape of leaf apices often occurs on single
individuals, as exemplified by leaves from different
branches of an individual collected near Motozintla,
Chiapas, Mexico (Fig. 23).
Most of the Mexican populations examined were
relatively constant in terms of leaf indument, al-
though occasional plants were more or less pubes-
cent than surrounding individuals. There did ap-
however,
pear to be, a significant amount of
variation in leaf shape among individuals from a
single population. Leaves from the "p wire at
Monte Alban (Fig. 24) ranged from 1.5 to 3.2 in
leaf length/width ratio and 45?
angle. The sampled population near Ciudad Men-
doza (Fig. 25) had leaf length/ width ratios of 1.7
to 3.4 and a range of 60? to 240? in basal angle.
If this degree of variation can be found in a single
to 100? eN apical
population, leaf apex, blade, and base shape are
not reliable characters for delimiting species.
Mean values and standard deviation are given
for characters of leaves from Mexican populations
of Ehretia latifolia in Table 4. Leaf length/ width
ratio, broadest point, apical angle, and basal angle
appear to be the best measures of overall leaf shape.

0.7-0.9 mm wide, glabrous externally, ciliate along
the interior margin; corolla white, tubular-cam-
panulate with 5 reflexed lobes, 4-4.6 mm long,
glabrous on the exterior surface, the lobes widely
oblong to oblong-ovate, 2.5-5 mm long, 1.3-1.7

the filaments flattened, 3-4.5 mm long, the upper
2-3 mm free, glabrous, the anthers ellipsoid, 1—
1.3 mm long; ovary ovoid to broadly ovoid, 1-1.2
mm long, 1 mm broad; style 2-3.4 mm long,
divided for 0.5-0.7 mm, the stigmas truncate.
Fruits drupaceous, yellow-orange, glabrous, broad-
ly ellipsoid, 5-7 mm long, 4-6 mm broad, the
endocarp dividing into 2, 2-locular pyrenes, these
ridged-reticulate on the outer surface.
Distribution. | Ehretia tinifolia occurs from
southeastern Mexico to Honduras and on Cuba,
Hispaniola, Jamaica, and the Cayman Islands in
lowland, moist to wet forests from sea level to
600(-1,500) m (Fig. 26). Collections cited from
Guerrero, Michoacán, Nayarit, San Luis Potosi,
and Sinaloa are not included in the distribution
map as they are presumed to be out of the natural
range of the species and are probably from culti-
vated plants.
Ehretia tinifolia is distinguished from the other
New World species by its glabrous, lustrous, entire-
margined leaves and elongate, paniculate inflores-
cence. It is widely cultivated, even outside of its
natural range for its attractive flowering and fruit-
ing display and as a shade tree.
The two species described by Miers, Ehretia
longifolia and E. sulcata, are both clearly syn-
onymous from Miers's description and their West
Indian distributions. Unfortunately, Miers cited
specimens with little information and these collec-
tions remain difficult to identify. For this reason,
these names have not been lectotypified, and syn-
types are cited here.

EXCLUDED SPECIES
The majority of names published in Ehretia for
the Neotropics are now considered synonyms of
Bourreria and Rochefortia. In the following list,
types have been examined when possible, but many
of the names can be excluded from Ehretia based
on the published descriptions. In placing the names
I have relied heavily on the revisions of Bourreria
(Miers, 1869; Schulz, 1911) and Rochefortia (Le-
for, 1968) supplemented with notes from John-
ston's extensive series of papers on the Boragi-
naceae. When FEhretia names are assigned to
species of Bourreria, they should be considered
cautiously as the best name available from the
literature since Bourreria is probably the most
nomenclaturally confused genus of Ehretioideae.

NEW AND CRITICAL TAXA
OF EUPHORBIACEAE
FROM SOUTH AMERICA!
Michael J. Huft?
ABSTRACT
Study of neotropical Euphorbiaceae for various floristic and taxonomic projects has uncovered several novelties.
New taxa pr
Colombia, Tragia ik ue e Peru, and the genus
the border of Panama and Color
oposed in this paper are Dalechampia liesneri from souther
Tacarcuna, including the thr
bia, 7. amanoifolia from Peru, an
ela, — S tomentosa from
ree new speci . gentryi, from
achirensis from ud. In addition it
n Venezue
is shown that Caryode Eon ee) irense Muell. Arg. is the correct name for ihe plant hitherto known as C. grandifolium
(Muell. Arg.) Pax
The Euphorbiaceae, one of the largest families
in the Neotropics, remains one of the least well
understood. The largest genera, Acalypha, Cro-
ton, Euphorbia, and Phyllanthus, have not been
critically revised in this century, and only a handful
of other, smaller genera have been the subject of
modern study. Even at the most basic descriptive
level, a great deal of work remains to be done, and
the mere discovery of a new species can often lead
to much insight into the taxonomy of its congeners.
Such is the case with the collection of taxa proposed
here, which result from study preparatory to the
Flora of the Venezuelan Guayana (J. Steyermark
& collaborators, in prep.), Checklist of the Flora
of Chocó Province, Colombia (A. Gentry & E.
Forero, in prep.), or from serendipitous discovery
in the herbarium.

Mueller published the name Centrodiscus gran-
difolius with description and citation of type. Be-
fore this went to press however, he added as a
separate item on a different page "Addenda and
Corrigenda” in which he pointed out that his Cen-
trodiscus grandifolius belongs to Karsten's genus
Caryodendron and that it differs from the only
species, Caryodendron orinocense Karsten, by,
among other things, having smaller leaves. Ap-
parently thinking that the epithet grandifolium
would be inappropriate in Caryodendron, he as-
signed the new plant the name Caryodendron ja-
neirense, which is the correct name for the species.
Centrodiscus grandifolius was not published be-
fore Caryodendron janeirense, pp. 273-754 of
Volume 11, Part 2, appearing together on May 1,
1874 (Stafleu & Cowan, 1981: 333-337). Mueller
was merely making a last-minute correction to text
already too far along in press to be changed in-
ternally. It is therefore clear that the name Cen-
trodiscus grandifolius Muell. Arg. was not ac-
cepted by its author when published and therefore
is invalid according to Article 34.1 of the /nter-
national Code of Botanical Nomenclature (Greu-
ter, 1988). The combination of Pax based on that
name is nomenclaturally superfluous. For the same
reason, the generic name Caryodendron Muell.
Arg., published simultaneously with Caryodendron
grandifolius Muell. Arg. and likewise not acc ee
by its author when published, is also invali

The pantropical genus Dalechampia contains
over 100 principally neotropical species. Numer-
ous recent discoveries (Armbruster, 1984, 1988,
1989; Huft, 1984; Webster, 1967, 1988; Web-
ster & Armbruster, 1979, 1982), many of them
of taxonomic and phylogenetic importance, attest
to the need for the critical study this genus is now
receiving at the hands of Dr. Grady L. Webster
and Dr. W. Scott Armbruster.
Dalechampia liesneri did to sect. Rho-
palostylis Pax & K. , the most primitive
section of the genus, which oni is restricted
to the northern and western Amazonian basin. Only
four species have previously been described from
this group: D. micrantha Poeppig from western
Brazil and eastern Peru, D. parvibracteata Lanj.
from the Guianas, D. olympiana Kuhlm. Ro-
drigues from northern Brazil, and the recently de-
scribed D. attenuistylus Armbruster from southern
Venezuela (Armbruster, 1989). The genus Mega-
lostylis S. Moore, whose only species, M. poep-
pigii S. Moore, appears to be based on an isotype
of D. micrantha, is synonymous with sect. Rho-
palostylis.
Section Rhopalostylis is characterized by ab-
sence of the showy white, pinkish, purplish, or
green bracts that are so characteristic of the rest
of the genus; absence of resiniferous glands in the
inflorescences; and larger, usually basally swollen,
styles. Dalechampia liesneri is distinctive in its
few-flowered, long-pedunculate, inflorescences and
long, thin styles that are not at all swollen toward
the base. Dr. Armbruster (pers. comm.), who is
preparing a revision of this group, has discovered
an additional population of this species near San
e Cataniapo (ca. of Puerto
Ayacucho) in southern Venezuela, and he reports
that it is probably not uncommon in that region.
It is a pleasure to name this species after Ronald
Liesner of the Missouri Botanical Garden who has
collected extensively in Venezuela during the past
decade and has been responsible for many discov-
eries and additions to our knowledge of the flora
of that country.

Tree to 25 m high, dioecious; twigs with thick
bark formed into flattened ridges and narrow fur-
rows, densely hirsutulous to glabrate toward apex.
Leaves alternate, short-petiolate; stipules obsolete;
petioles 0.5-2.5 cm long, stout, densely hirsutulous
to glabrate; blades chartaceous to subcoriaceous,
broadly obovate-elliptic, 10-23 cm long, 7-12 cm
wide, 1.5-2.8 times as long as wide, densely brown
tomentose to glabrate below, moderately pilose to
glabrate above, the apex rounded, obtuse, or short-
acuminate, the base rounded, obtuse, or broadly
cuneate, the margins entire to obscurely crenate-
undulate; midrib prominent below, the secondary
nerves 14-26 on a side, parallel, arching somewhat
toward the margin of the blade, prominent below,
light-colored above, neither raised nor impressed,
the tertiary veins connecting the secondaries at
right angles, regularly spaced, prominulous below.
Inflorescences numerous, lateral, below current
leaves, RE of clustered M 2-4 cm
long, t ly brown tomentose when young,
becoming densely puberulent at maturity. Stami-
nate flowers 1-3 in sessile or subsessile glomerules,
the buds globose, 0.7-1.1 mm diam. Pistillate
flowers not seen, sessile or short-pedicellate; calyx
persistent on young fruits, tomentose outside, the
lobes 1-1.5 mm long, deltate, ca. 25 the length of
the calyx; young fruits densely brown tomentose,
pyriform, the styles 3, ca. 1 mm long, strongly
ecurved, united at base, glabrous or with a few
scattered. hairs. Capsules ellipsoid-obovoid, ob-
scurely trigonous, glabrous, smooth, 11-16 mm
the styles persistent, minute,
long, 6-9 mm diam.,
the columella with broad papery wings, not per-
sistent.
This very distinctive species is easily distin-
guished from the four to six other species of Rich-
eria by the densely tomentose lower leaf surfaces
on many specimens and by the short, compact,
highly branched inflorescences. The prominent
midrib and secondary veins are also distinctive.
The widespread R. racemosa (Poeppig) Pax &
Hoffm. has staminate spikes longer than the leaves
rather than the short, compact, clustered panicles
that are characteristic of R. tomentosa, and the
cymules are distinctly pedunculate and two- or
three-flowered. Two other South American species,
R. grandis Vahl and R. obovata (Muell. Arg.) Pax
& K. Hoffm., have longer and less compact inflo-
rescences than R. tomentosa and are completely
glabrous; their leaf margins are prominently cre-
nate-undulate (vs. entire or obscurely crenate-un-
dulate). The recently described R. dressleri Web-
ster (Ann. Missouri Bot. Gard. 75: 1094. 1988),
from Panama and apparently Costa Rica, is dis-
tinctive in its two-carpellate ovaries and fruits.

quite unlike any other Euphorbiaceae in the Neo-
tropics, and I have been unable to match it with
any Old World representatives of the family. The
collections available have mature capsules and
young fruits that retain the pistillate calyx and
corolla. Only one specimen (T. gentryi, Gentry et
al. 16901 MO), however, has staminate flowers,
and these are partially embedded in mounting glue.
Additional material of 7. gentryi containing abun-
dant staminate flowers was collected but has ap-
parently been lost or misplaced (A. Gentry, pers.
comm.). Since characters of the staminate flowers
are of great importance in generic delimitation in
the Euphorbiaceae, I have been reluctant for some
time to describe this new genus, pending recovery
or re-collection of staminate material. However,
partial dissection of the available staminate flowers
revealed five free stamens and a well-developed
staminode; these features along with the glomerate,
axillary inflorescences, presence of petals, and im-
bricate calyx mark this as a previously undescribed
genus.
Only recently have collections of two additional
species of this remarkable genus come to light,
and, even though staminate material is lacking in
these species, all three species are described to-
gether in the hopes of stimulating further explo-
ration. In addition to the characters already men-
tioned, the three species of Tacarcuna are held
together by the combination of ovate-lanceolate or
obovate-lanceolate leaves with very short, stout
petioles; the sepals and often the petals more or
less densely puberulous centrally on the outer sur-
face, and with distinctly hyaline margins; deeply
lobed capsules somewhat depressed at the apex;
and a network of low ridges on the mature capsules,
especially prominent in 7. gentryi, less so in T.
amanoifolia, and largely obscured by the veluti-
nous indument in 7. tachirensis.

This is the only species of Tacarcuna known
from lowland areas; the two collections were made
in occasionally inundated mature forest at ca. 0-
100 m elevation. The leaf blades of T. amanoifolia
are thicker and more lustrous than in 7. gentryi,
and are marked by their more or less broadly
obovate-lanceolate outline with a conspicuous cus-
pidate-acuminate tip. These features along with a
sometimes lighter color along the margins impart
to the leaves an appearance strikingly similar to
that of 4manoa guianensis Aublet, a widespread
euphorbiaceous tree of the lowland forests of north-
ern South America and southern Central America.
Its short mature pedicels give the fruiting branch
a more congested appearance than in T. gentryi.

cernible wings running the length of the axis, these
rarely larger and membranous; seeds smooth,

This species is known only from a single collec-
tion on steep forested slopes above 1,200 m. Only
post-mature (i.e., already dehisced) capsules are
available. The capsules are distinctive in their
densely velutinous indument. The leaves are similar
to those of 7. amanoifolia in their thicker texture
and lustrous surface, but are more characteristi-
cally lanceolate-ovate rather than lanceolate-ob-
ovate, and have more closely spaced and more
numerous secondary veins; the tips are acute (rare-
ly short-acuminate) rather than prominently cus-
pidate-acuminate as in T. amanoifolia.

This unusual species would key to sect. Bia
(Klotzsch) Muell. Arg. in the treatment of Pax &
Hoffmann (1919) on the basis of its five stamens
and the presence of disk glands in the staminate
flowers, but it seems hardly related to the other
species of that section, which are characterized by
their usually deeply cordate leaves (except 7. les-
sertiana (Baillon) Muell. Arg.) and especially their
robust, bipartite inflorescences with one branch
staminate and the other pistillate. Were it not for
the presence of the disk glands, however, Tragia
rubiginosa might seem almost at home in the Cu-
ban genus Platygyne Mercier, which Pax & Hoff-
mann distinguished from Tragia by unisexual (vs.
androgynous) inflorescences, 5-15 (vs. 2-50 usu-
ally near the lower end of the range) stamens,
globose hairy receptacles, free filaments, absence
of a disk, and wide styles emarginate at the apex.
Liogier (1971: 132, 133) was spurred by his
study of the Hispaniolan species Tragia biflora
Urban, which closely resembles Platygyne, to in-
vestigate the relationship between Tragia and Pla-
tygyne. He found that the generic characters are
intermixed in some species referred to Platygyne,
and particularly in 7. biflora, which has a globose,
glabrous receptacle with 10-20 stamens and wide,
but not emarginate, styles. His conclusion that
Platygyne cannot be kept separate from 7ragia
is bolstered by the existence of 7. rubiginosa,
which has the five stamens and monoecious inflo-
rescences typical of Platygyne but has a disk, flat
glabrous receptacle, and nonemarginate styles. The
inflorescences of T. rubiginosa are reminiscent of
those of T. biflora, which likewise are monoecious,
axillary, and somewhat reflexed, although consid-
erably shorter and with a less pronounced peduncle.
The leaves also seem similar but are longer, nar-
rower, and less coarsely crenate in 7. rubiginosa.
The specific epithet refers to the red-brown color
of the flowers.

Ampelocera is a little-known genus of nine is anomalous within the Ulmaceae by virtue of its
species of neotropical trees. Although a frequent 4-16 stamens. On the basis of a summation of
component of some low- to mid-elevation neotrop- evidence from various sources (morphology, anat-
ical forests (A. Gentry, pers. comm.), Ampelocera omy, embryology, palynology, and flavonoid chem-
is poorly represented in herbaria because it is a istry), Tobe considers Ampelocera best classified

Ampelocera.
MORPHOLOGY AND TAXONOMIC
CHARACTERS
Ampelocera species are small to large trees often
with slender, channeled buttresses and smooth gray
bark. The wood is light brown to cream-colored
and hard.
LEAVES
The leaves of all species are pinnately veined
except for those of Ampelocera hottlei, which are
trinerved at the base. The texture of most leaves
is coriaceous, but 4. cubensis and A. macphersonii
have chartaceous leaves. The leaves of Ampeloc-
era are glabrous except for those of 4. cubensis,
which are sometimes softly puberulent beneath.
Young leaves in most species are often many times
larger than those on fertile branches. Young leaves
of A. hottlei and A. macrocarpa are distinctive
for their bright blue metallic color.
Nearly all leaves of Ampelocera are oblong to
elliptic with characteristic oblique bases and atten-
uate apices. Ampelocera cubensis, A. glabra, and
A. ruizii often have obscurely and coarsely dentate
leaves. Petioles are usually thick and have a red
flaky epidermis.
INFLORESCENCES
Ampelocera inflorescences are axillary, some-
times simple, usually compound dichasia or rarely
are panicles of compound dichasia. In A. glabra
the rachises are so short that the inflorescences
appear fasciculate. The longest and most densely
flowered inflorescences in the genus with up to 56
flowers are found in 4. longissima. Inflorescences
have perfect flowers and functionally staminate
flowers, the latter being found lower on the inflo-
rescence axis.
FLOWERS
Ampelocera flowers are small, cream-colored,
yellow, or green and offer a limited number o
characters. All dimensions provided in the descrip-
tions are based on dried material. The perianth
consists of a sepalar cup with four or five usually
sparsely puberulent lobes. The lobes in 4. cubensis
are villous.
Stamen number varies from 4 to 16 with the
staminate flowers often having fewer stamens (4—
8) than the perfect flowers. Two kinds of filaments
are found in the genus: relatively thick filaments
expanded near the base and drying flat characterize
A. edentula and 4. macrocarpa, and relatively
long, thin filaments that twist upon drying char-
acterize the other seven species. The anther con-
nective is extended beyond the thecae to form a
strigose apicule. In the species with the short, broad
filaments, the connective extension is very pro-
nounced, while in those with long, thin filaments,
the extension is smaller.
The ovary in Ampelocera is puberulent and
oblong to globose. The two style branches are free
to the base in most species, but in 4. cubensis and
A. ruizii they are united in the lower one-fourth.
Staminate flowers often have cylindrical, ribbed
pistillodes with the same vestiture as the ovaries
in the perfect flowers.
Size and shape of the drupaceous fruits of each
species of Ampelocera are quite distinctive. Gen-
erally the fruits of Ampelocera are yellow, asym-
metrical, and transversely obovoid or ellipsoid; they
vary from 0.6 to 2.2 cm long. The fruits may be
glabrous (4. glabra, A. longissima), sparsely pu-
berulent (4. edentula, 4. macrocarpa), densely
pubescent (4. macphersonii), or densely pilose (A.
rulzil).
usual in the genus, are symmetrically oblong and
velutinous with longitudinal striations. Ampelocera
Ampelocera hottlei fruits, the most un-
macrocarpa typically has pyriform fruits with an
unusually thick endocarp.
USES
The wood of Ampelocera is hard and is used
for firewood and lumber. In the Pichis Valley of
Peru, the astringent bark of 4. edentula is used
by the Campa Indians to tattoo skin. The bark is
wetted and then bound around the arm, where it
ulcerates the skin and causes a painful eruption.
A coloring agent is then applied to the ulceration
and scar tissue forms (A. Gentry, pers. comm.).

This species is characterized by relatively small,
thin, sparsely dentate leaves; short, fasciculate in-
florescences that are borne on leafless branches;
style branches 3-4 mm long; linear filaments; and
small, puberulent, strongly asymmetrical fruits.
Ampelocera cubensis is closely related to A. gla-
bra from central coastal and southeastern Brazil
and 4. ruizii from Amazonian Brazil, Peru, and
Bolivia. It differs from 4. glabra by having smaller
fruits and less prominently dentate leaves and dif-
fers from 4. ruizii by having shorter inflorescences
with 2-5 (vs. 8-23) flowers and by having sepals
1.5 (vs. 2-2.5) mm long.
Morton (1958) described Ampelocera pubes-
cens, distinguishing his new species from 4. cu-
bensis by the vestiture of the lower leaf surface
and the length of the stipules (4.5-6 mm in 4.
pubescens vs. 3 mm in A. cubensis). | can find
no other characters to corroborate the recognition
of two taxa, and, in fact, vestiture of material
annotated as 4. pubescens by Morton, including
the type (Jack 6036), ranges from densely to
sparsely pilose.

Ampelocera edentula is characterized by having
flowers with eight stamens; broad filaments with a
pronounced terminal extension of the connective;
and large yellow, globose, symmetrical fruits. This
species is most closely related to A. macrocarpa
from which it differs in having generally oblong
fruits and a thin endocarp (vs. globose fruits and
a thick endocarp).
In his description of Ampelocera latifolia, Ducke
(1943) stated that his new species might be just
an upper-Amazonian variant of 4. edentula. The
fruit on the type of 4. latifolia is distinctly oblong
while that on the type of 4. edentula is smaller
only a difference in fruit maturity, and since I
could find no other consistently correlated char-
acters, A. latifolia is placed into synonymy with
A. edentula.
Although Ampelocera edentula occurs through-
out a broad geographic area in the Amazon Basin,
it is poorly represented in herbaria, and conse-
quently, its morphological variation is difficult to
assess.
branches,
eaves are generally shorter on fertile
12-20 cm long, while sterile branches
have leaves up to 30 cm long. Some collections
from Peru and Bolivia (Schunke 4395, Woyt-
kowski 7307 (Perú: Dept. San Martin); Krukoff
10727 (Bolivia: La Paz)) have leaves up to 35 cm
on fertile branches. These populati liffer further
from typical Brazilian 4. edentula in have shorter
petioles, more oblique leaf bases, and more pubes-
cent fruits. A sterile specimen from Peru (Dept.
Loreto: Prov. Requena, Jenaro Herrera, Rio Uca-
yali, 73°45'W, 4%55'S, 22 Feb. 1987, Gentry et
al. 56289 (MO)) is unusual in having sparsely
pubescent stems, petioles, and the lower surface
of the primary and secondary veins. As more spec-
imens become available, the variation presently
included in 4. edentula may warrant recognition
of other taxa.

Ampelocera glabra is distinguished by its small
fascicles of flowers; large, strongly asymmetrical,
glabrous fruits; and toothed leaves. It is clearly
most closely related to and can be easily confused
with A. ruizii but is geographically disjunct. The
straight instead of arcuate lateral veins in A. glabra
are distinctive in the genus.

Ampelocera hottlei is represented by the most
collections and thus is the best-known species in
the genus. Unlike other species, description of the
trunk, bark, and sap is available from collection
data. It is distinguished from all other species by
its trinerved leaf base, and obovoid, densely pu-
bescent, longitudinally lined fruits. As with 4. mac-
rocarpa, the young leaves are bright metallic blue.

Ampelocera macrocarpa is characterized by its
large fruits with a very thick endocarp, relatively
short petioles with flaky red epidermis, and short
style branches. The leaves of this species are bright
metallic blue when young and have strongly oblique
bases. On saplings and young branches the leaves
are extremely long and narrow (22-38 cm long).
Ampelocera macrocarpa appears to be most closely
related to 4. edentula by virtue of the characters
given in the key.

Ampelocera macphersonii is distinctive in hav-
ing entire leaves and small, orange, strongly asym-
metrical, transversely obovoid fruits. By virtue of
its 16 stamens it is allied to 4. pubescens, A.
glabra, and A. ruizii. It differs from A. pubescens
by having glabrous leaves and racemose (not glo-
merulate) inflorescences, and from both 4. glabra
and A. ruizii by having entire (not dentate) leaves
and larger fruits. Vegetatively A. macphersonit
resembles 4. longissima but can be separated eas-
ily by the characters provided in the key. The
occurrence of A. macphersonii in deciduous and
semievergreen forests is unusual for the genus.
This species is named in honor of Dr. Gordon
McPherson whose collecting efforts in Panama have
yielded many new and interesting plants.

Ampelocera ruizii is distinguished from 4. gla-
bra by having smaller fruits and longer inflores-
cences. They are similar in having dentate, gla-
brous leaves and transversely ellipsoid, asymmetrical
ruits.
Baehni (1937) separated Ampelocera from Pla-
gioceltis and the other Peruvian genera of the
maceae on the basis of the former having twice
many stamens as the latter. The isotype of
Plagioceltis dichotoma at F, however, has a great-
er number of stamens than perianth parts. Since
stamen number is not mentioned in the Plagioceltis
description, Baehni’s misplacement of the genus in
the Flora of Peru key alongside genera possessing
equal numbers of stamens and perianth segments
is probably due to Mildbraed's inadequate notes
(Gentry, 1983). As mentioned under taxonomic
history, the similarity of the unnumbered Ruiz &
Pavón type specimen of Plagioceltis dichotoma
and the type of Ampelocera ruizii is the most likely
because both originated from the same collection.

The genera Nivenia (nine species), Klattia (three
species), and Witsenia (one species) comprise a
natural alliance of Iridaceae, restricted in distri-
bution to the southwestern Cape region of southern
Africa. Uniting the genera are the following spe-
cialized characters: a shrubby evergreen habit; a
woody rootstock and aerial stems both having ap-
preciable secondary growth; nonfugacious flowers
with a well-developed perianth tube and bearing
septal nectaries; tangentially compressed seeds; and
a specialized leaf anatomy with submarginal scle-
renchyma and girders produced by the extension
to the epidermis of the sclerenchyma surrounding
some of the vascular bundles (Goldblatt, in prep.;
Goldblatt & Bernhardt, in press; Manning & Gold-
blatt, in prep.; Rudall & Burns, 1989).
This study of the pollen morphology of the three
genera was undertaken in conjunction with a broad-
ly based investigation of their systematics and re-
productive biology, the latter focusing particularly
on the heterostylous condition in five species of
Nivenia. 'These distylous species are made up of
populations of plants with either long styles and
short stamens or short styles and long stamens. In
many plants heterostyly is often associated with
pollen dimorphism (Ganders, 1979; Richards, 1986)
and this phenomenon has been considered in our
examination of exine structure. The homostylous
Klattia and Witsenia were included in our study
for the sake of completeness. Klattia and Witsenia
are probably bird pollinated (Rebelo, 1988; Gold-
blatt, in prep.) in contrast to species of Nivenia
which are pollinated by long-tongued insects, either
anthophorid bees or nemastrinid flies (Goldblatt &
Bernhardt, in press). Any differences in the pollen
of the three genera may be significant in light of
the differences in their pollination biology.
MATERIALS AND METHODS
Pollen taken from herbarium specimens of 11
species (Table 1) was treated in one of two ways.
For examination of exine sculpturing alone, un-
treated grains were glued on aluminum stubs an
sputter coated with gold. For examination of whole
grains, unacetolyzed pollen was rehydrated by
warming in 10% KOH for ca. 10 minutes, then
dehydrated in ethanol, rinsed twice in 50% acetone

(Table 3
OBSERVATIONS
Grains of all species of all three genera are more
or less spherical (Figs. 1-6), ranging from near
prolate to near oblate depending on the species
(Table 2). The monosulcate grains have a promi-
nent elliptic to oblong sulcus (Figs. 2, 5, 6);
are tectate-perforate in Witsenia with a micro-
reticulate tectum (Figs. 4-6, 9, 10) and semitectate
with a reticulate tectum in Nivenia and Klattia
(Figs. 1-3, 7, 8). The floors of the lumina in all
the species are granulate (e.g., Fig. 7). The muri
are smooth in Klattia (Fig. 8) but minutely gran-
ulate in /Vivenia and Witsenia (e.g., Figs. 7, 9,
10). In N. binata and N. stenisiphon the sides of
the muri are irregularly ridged (e.g., Fig. 7) (Table
2).
In Nivenia the luminae range from about as
wide as the muri (microreticulate), e.g., /V.
cinna (Fig. 12), to about twice as wide (reticulate),
or up to four times as wide in N. capitata (Fig.
11)
Supratectal gemmae (ca. 4 um in diameter) are
restricted to Witsenia (Figs. 5, 6) and are scattered
more or less evenly across the surface.
The exine sculpturing ends abruptly at the sulcus
(Fig. 2) in Nivenia and Klattia, but in Witsenia
the muri become disrupted into pilae and baculae
(Fig. 10) along the sulcus margins.
Pollen grain diameter ranges from 44.69 um in
the long-styled morph of /Vivenia corymbosa to
over 80 um in Klattia stokoei and Witsenia maura
(Table 2). Differences in pollen grain size among
the species correlate generally with differences in
style length. Klattia and Witsenia have the longest
styles and largest pollen in the group, and K. sto-
koei the longest styles in that genus. Nivenia le-
vynsiae and N. concinna, however, do not follow
this trend, having shorter styles than one would
expect from their comparatively large pollen grains.
In four of the five heterostylous species of Niv-
enia the grains of the long-styled morph are sig-
nificantly smaller (Table 3). Pollen size differences
between morphs of the four heterostylous species
late directly with differences in style length
also
in the complementary morph (Goldblatt & Bern-
hardt, in press). Exine sculpturing does not differ
between morphs within the heterostylous species,
ut there are notable di the
species. Nivenia binata exhibits the greatest de-
gree of sculpturing and V. capitata the least (Figs.

DISCUSSION
The pollen grains of Nivenia and Klattia con-
form fairly closely to the presumed basic type for
Iridaceae and for the monocots in general, in which
reticulate grains appear to be fundamental (Schulze,
1971; J. Walker, pers. comm.). Similar grains are
found in species of Aristea (likewise Nivenioideae)
and in numerous genera of Iridoideae, excluding
Iris, in which there are multiple unusual special-
izations, particularly in the form of the aperture
(Schulze, 1971). A group of New World genera of
Iridoideae belonging to the tribe Tigridieae stand
out in having bisulcate grains (Schulze, 1971),
clearly a secondary condition in the tribe. Members
of subfamily Ixioideae also differ markedly from
this basic pollen type, having a tectate-microper-
ith supratectal spinules (Erdtman,
Goldblatt & Stein, 1988).

size of the lumina of the reticulum, leading to a
microreticulate pattern in N. fruticosa and N. con-
cinna. These two species appear to be indepen-
dently specialized based on differences in flower

and inflorescence morphology (Goldblatt, in prep.),
and their similar pollen sculpturing is presumably
convergent. The occurrence of ridged muri in N.
binata and N. stenosiphon, however, appears to
be an indication of close taxonomic relationship as
it is correlated with two specialized characters re-
stricted to these species: blue anthers and pollen,
and large, dry, brown, crisped bracts (Goldblatt, in
prep.).
The grains of Witsenia, with their large supra-
tectal gemmae, are clearly derived. These distinc-
tive gemmae, observed by Schulze (1971) under
light microscopy, are unique in Iridaceae and make
the pollen grains of this genus immediately rec-
ognizable. The presence of an unusual exine in
Witsenia emphasizes the taxonomic isolation of this
genus, distinctive in its unusual floral and inflores-
cence morphology. Any significance in the elabo-
rate exine sculpturing of Witsenia in relation to
its mode of pollination remains to be demonstrated.
Pollen sculpturing does not provide any char-
acter uniting the three shrubby genera of Cape
Iridaceae, but within the alliance trends of spe-
cialization are evident in Nivenia, and the supra-
tectal gemmae in Witsenia constitute an autapo-
morphy for this genus.
Mulcahy's (1965) report of a difference in size
between the grains of the short- and long-styled
morphs of N. binata is substantiated by our ob-
servations, although we noted a smaller size dif-
ference (ratio of grain size between short- vs. long-
styled morph 1.11 compared with 1.3 reported by
Mulcahy). We were unable to confirm Mulcahy's
observation of differences in the size of the lumina
of the exine reticulum between short- and long-
styled grains in N. binata, nor did we record mea-
surable differences in lumina size in the other het-
erostylous specie
e close similarity of the exine sculpturing and
small, though statistically significant, differences in
pollen grain size between the two style morphs in
four of the observed heterostylous species of Niv-
enia are consistent with similar observations in
many heterostylous taxa (Ganders, 19 Rich-
ards, 1986). In Nivenia the noolar ea differ-
ences between the style morphs of the heterostylous
species appear not to be accompanied by the ex-
pected self-incompatibility characteristic of most
heterostylous plants (Goldblatt & Bernhardt, in
press).

(IRIDACEAE—
SISYRINCHIEAE)
AND ITS ALLIES!

and Richard C. Keating?
ABSTRACT
Seeds of 25 species of sects. Sisyrinchium, Echthronema, Eriphi ilema, and iai of the large North and South
— genus Sisyrinchium were examined using the scanning e electron mic
eeds of representative species of related genera in tribe Sisyrinc ditas. Seeds of sects. Sisyrinchium
, are s with Vg nd surfaces, and often have a iuis depression,
compared with s
and Echh ronema are more or less Pomen
a large, half-circumferential wing. Seeds o
probably derived specializations. Based on seed charac
and light microscope and
o have brown, more or lessa ular seeds ms

to the other genera of Sisyrinchieae, particularly Phones than to sects. Sisyrinchium or Echthronema.
In the course of a systematic study of the New
World genus Sisyrinchium for Flora Mesoamer-
icana (Henrich & Goldblatt, 1987, in press a) and
Flora de Nicaragua (Henrich & Goldblatt, in press
b) our attention was drawn to the unusual rounded,
blackish, umbilicoid seeds of the genus. The seeds
were novel to us in Iridaceae and distinguish Sisy-
rinchium from all other genera in the family.
Seed characters were also useful in establishing
species limits within the genus. We found no ad-
equate description or record of Sisyrinchium seeds
in the literature, and Huber (1969) did not spe-
cifically describe them in his extensive study of the
seeds of lilioid monocots. However, Cholewa &
Henderson (1984) included SEM examination of
six North American species of sect. Sisyrinchium,
and Rodriguez (1986) mentioned color and surface
texture in his revision of the Chilean species of
Sisyrinchium.
With this background we undertook the present
survey of the seeds of Sisyrinchium and its allies
in tribe Sisyrinchieae of subfamily Iridoideae (clas-
sification after Goldblatt, 1990). Sisyrinchium as
presently constituted (Bentham & Hooker, 1883;
Baker, 2)
study includes a small but representative sample
of the total and is sufficient to satisfy our purpose
in documenting the basic seed types found in the
genus and to allow a valid comparison with allied
genera. We included taxa from the two large and
apparently natural sects. Sisyrinchium (— sect.
Bermudiana of several authors) and Echthronema
(Bentham & Hooker, 1883) and the smaller sects.
Eriphilema and Nuno. Related genera of tribe
Sisyrinchieae (sensu Goldblatt, 1990) examined for
comparison were Libertia, Ona, Orthrosanthus,
Phaiophleps, Solenomelus, and Tapeinia. Seeds
of Chamelum, which belongs in this alliance, were
not available. The southern African Bobartia and
the Australian Diplarrhena, the remaining genera
of the tribe, appear to be more distantly related to
the Sisyrinchium complex and neither was in-
cluded in our survey. Sections Eriphilema and
Nuno and the other genera examined have seeds
comprises over 100 species. Our

fairly typical of Iridaceae in their brownish color
and more or less angular shapes (Huber, 1969)
and are very different from the seeds found in
sects. Sisyrinchium and Echthronema.
MATERIALS AND METHODS
Mature seeds were assembled from herbarium
material, and in a few cases fresh field-collected
seeds were examined (Table 1). We excluded seeds
that appeared deformed or showed signs of fungal
infection. Seeds were examined under the light
microscope for size and color, and then prepared
for the scanning electron microscope (SEM) study
by attachment with water-soluble white glue to
aluminum stubs and sputter coating with 500—700
À of gold. They were examined in an ISI Super IIIA
SEM at 15 kV.
OBSERVATIONS
COLOR
Seeds of all the species of Sisyrinchium sects.
Sisyrinchium and Echthronema are blackish (Ta-
ble 2). Surface color intensity ranges from a fairly
glossy, intense black to matte and dark gray. As
we used seeds almost exclusively from herbarium
specimens, we are uncertain how much significance
to attribute to the color variation as ripening may
have been affected by the rapid drying, and the
final seed appearance may thus not be the same
as in nature.
Seeds of Sisyrinchium sects. Eriphilema and
Nuno and of the genera Libertia, Ona, Orthro-
santhus, Phaiophleps, Solenomelus, and Tapei-
nia are shades of brown (Table 2), most often red-
brown, presumably the basic condition in the family
(Huber, 1969) and an indication of the presence
of the pigment phlobaphene. Some species, for
example Orthrosanthus occissapungus, have light
brown seeds, an apparently significant character
at the species level.
SHAPE AND SIZE
The number of seeds per locule of the three-
chambered capsules of Sisyrinchieae was not re-
corded in our study, but all species examined have
multiseeded loculi. The effect of crowding and al-
teration of shape by mutual pressure within the
locules (Huber, 1969; Wagner & Goldblatt, 1984)
was noted to some degree in most species. Angular
seeds characterize Libertia and Orthrosanthus
(Figs. 1-3). Phaiophleps and Sisyrinchium sect.
Eriphilema have less sharply angular seeds (not
illustrated), sometimes tending toward rather ob-
tusely angled and differing consistently in basic
shape from the rounded seeds of sects. Sisyrin-
chium and Echthronema. Seeds of two species of
Solenomelus are cylindric to barrel-shaped with
distorted angular ends (e.g., S. segethii, Fig. 5).
In a third, possibly new, species of Solenomelus
(Fig. 6) the seeds have a broad, membranous, half-
circumferential wing. The seeds of Orthrosanthus
occissapungus (Fig. 3) have the proximal and dis-
tal ends produced into winglike processes, but other
species of the genus have angular seeds, as illus-
trated by Takhtajan (1985) for O. chimboracensis.
In Tapeinia (Fig. 4) the seeds are nearly pyriform
to elongate-pyriform, narrowest at the chalazal end.
The raphe is usually distinct and terminates in a
small depression in which we assume the micropyle
is located. The least effect of crowding was found
in sects. Sisyrinchium and Echthronema. There,
except for the small persistent funicle, the seeds
(Figs. 7-18) are nearly regularly spherical to
rounded or sometimes somewhat depressed (e.g.,
S. chiricanum, Fig.
Seed size varies considerably (Table 2) within
genera. Thus in Sisyrinchium, S. minus has seeds
6 x 0.4 mm, whereas those of S. chiricanum
are ca. 2.5 mm in diameter. The seeds of Soleno-
melus are even larger, with a maximum length of
5.5 mm attained by Solenomelus sp.
There is a regular pattern of small, evenly spaced,
irregularly rounded depressions oriented in lines
running along the long axis of the seeds of all three
species of Solenomelus (Figs. 5, 6). In Solenomelus
sp. these depressions are limited to the area cov-
ering the seed body.
A conspicuous, often large pit, which we here
call an umbilicus, is an outstanding feature of the
seeds of most species of sects. Sisyrinchium (Figs.
9, 10) and Echthronema (Figs. 13-18) (Table 2).
The umbilicus straddles the raphe, either between
the hilum and the micropyle (Figs. 17, 18), or the
umbilicus includes the micropyle (Figs. 13, 15).
SURFACE MORPHOLOGY AND MICROSCULPTURING
Outlines of the testa cells often form a pro-
nounced reticulum owing to the typical condition
in Iridaceae for the outer periclinal walls to collapse
while the thickened anticlinal walls persist (e.g.,
Figs. 1-4). The seed surfaces thus have a reticulate
appearance
the surfaces exhibit little texture and in S. trinerve
Fig. 15) are nearly smooth. We did not find ex-
amples of the somewhat irregularly granular sur-

In Solenomelus the longitudinal lines of more
or less circular depressions do not correspond to
the surface cells. The depressions are larger than
the individual cells, the outlines of which can be
clearly seen over the entire seed surface in S.
segethii (Fig. 5), but are rather obscure in Soleno-
melus sp. (Fig. 6) and S. pedunculatus. In the
latter the peripheral cells of the seed are unusual
being elongate and they have a remarkably
smooth surface (Fig. 20)
DISCUSSION
Most Iridaceae have seeds of a light to middle
brown, sometimes reddish brown (Huber, 1969;
Wagner & Goldblatt, 1984), the coloration attrib-
uted to the presence of phlobaphene (Huber, 1969).
A few exceptions include the glossy black seeds of
Belamcanda (tribe Iridoideae) and Babiana and
Antholyza (tribe Ixioideae), and the bright orange
seeds of Chasmanthe (also Ixioideae) and Neo-
marica variegata (Iridoideae tribe Mariceae).
Whether the black color in the above genera or
in Sisyrinchium can be attributed to the presence
of phytomelan, a dense carbon substance that is
regarded as important in the higher systematics of
the lilioid monocots (Dahlgren & Rasmussen, 1983;
Dahlgren et al., 1985), is unknown.
The most common seed shape in lridaceae is
more or less regularly angular (Huber, 1969) but
globose or subglobose seeds are not uncommon.
Winged seeds occur in Gladiolus and its close allies
(Ixioideae), and discoid seeds are characteristic of
ee details of seeds of Sisyrinchium commutatum (19) and Solenomelus pedunculatus
some species of /ris and Moraea (both Iridoideae-
Irideae) and Diplarrhena (Sisyrinchieae). The half-
circumferentially winged seeds of Solenomelus sp.
are reminiscent of those of Gladiolus (which have
completely circumferential wings) and represent a
notable example of convergence.
Until now the blackish seeds encountered
Sisyrinchium appear not to have been regarded
as particularly significant, although the basic dif-
ferences in seed color have been noted by Rodri-
guez (1986), black in species attributable to sects.
Sisyrinchium and Echthronema and brownish in
sect. Eriphilema. Moreover, the more or less glo-
bose shape and the frequent presence of a large
umbilicus along the raphe, either between the hilum
and micropyle or including the latter, appear to
have attracted little attention except for occasional
mention in species descriptions. We believe that
these features have considerable taxonomic signif-
icance, particularly in a. genus that is relatively
unspecialized in the family and has few other dis-
tinguishing characteristics.
A conclusion that appears warranted is that the
black,
(apomorphic) condition in sects. Sisyrinchium and
globose, and umbilicoid seeds are a derived
Echthronema. It is likely, though by no means
certain, that this seed, including the umbilicus, is
the basic type in the two sections despite the fact

NEW SPECIES OF Dieter C. Wasshausen?
MENDONCIA
(ACANTHACEAE) FROM
THE VENEZUELAN GUAYANA!
ABSTRACT
ecent expeditions in the Venezuelan Guayana have resulted in additional new taxa in the genus d
ea eae). The following is an effort to place these novelties on record for the convenience of other taxonomists
prior to the publication of the Flora of the Venezuelan Guayana. Four new Venezuelan Guayana species of Me ndoncia,
M. steye dea M. neblinensis, M. williamsii, and M. coriacea, are described, Juétratea, por compared with their
closest relatives
There are approximately 60 species of Men-
doncia in Central and South America and in trop-
ical Africa and Madagascar. The genus, named for
Cardinal Mendonca, Patriarch of Lisbon, consists
of twining herbaceous or sometimes suffrutescent
climbers bearing cylindric red, white, or cream-
colored axillary flowers with purple streaks in the
throat. Each flower is subtended by a pair of con-
spicuous, green, more or less connate bracts. Most
taxa are limited to wet virgin forests and thickets
at elevations between 50 and 1,000 m. Due to the
fact that lianas and vines are generally poorly known
and collected in the tropics, and given the super-
ficial similarity of many of the species, the tax-
onomy of the genus is rather difficult. In an attempt
to identify recent collections of Mendoncia from
the Venezuelan Guayana, I have found four un-
described species of the genus.

Mendoncia neblinensis is probably related to
M. sprucei Lindau. It differs markedly from M.
sprucei in that the latter species has green bracts
2 cm long and 1 cm broad, sparingly appressed-
pilose pubescence on the leaf blades, and corollas
3 cm long. In contrast, M. neblinensis has yel-
lowish to brownish green bracts cm long
and 1.3-1.7 cm broad, glabrous leaf blades, and
corollas 3.5 cm long. Lindau (1897) in his de-
scription of M. sprucei did not indicate the color
of the corolla, nor did Turrill (1919) in his revision
of the genus. Leonard (1951) described the corolla
f M. sprucei as cream colored with purple streaks
5:
in the throat. I believe this to be in error; the
corolla of M. sprucei is also bright red. Turrill
(1919) stated in his discussion that M. sprucei
appears to be very closely related to the red-flow-
ered M. aspera Nees and that perhaps M. sprucei
was only a variety of M. aspera.

Mendoncia williamsii is most closely (but dis-
tantly) related to M. sprucei Lindau. In M. sprucei
the bracts are ovate and sparingly appressed-hir-
tellous without; the flowers are usually solitary; and
the leaf blades are ovate to oblong-ovate, firmly
membranous, and about 6 cm broad. In contrast,
in M. williamsii the bracts are oblong-lanceolate
and densely brown strigose without; the flowers are
usually in twos; and the leaf blades are elliptic,
chartaceous, and considerably wider (about 7.5 cm
broad).

Mendoncia coriacea is perhaps most closely
related to the widespread lowland Amazonian species
of Colombia and Peru, M. pedunculata Leonard,
which differs markedly by having larger (4 cm long,
1.4-1.8 c road), violet bracts; membranous,
wider (6-10 cm broad) leaf blades; and longer,
white corollas marked by reddish brown within and
to © cm long. In contrast, M. coriacea has
coriaceous, vinaceous-lavender with green bracts
2.5-3.5 cm long and 1-1.4 cm broad; subcoria-
ceous to thick-coriaceous leaf blades 3.5-6 cm
broad; and shorter (4.5 cm long), white, internally
lavender-striped corollas.

l. Terminalia chicharronia Wright ex Sau-

Restricted to Cuba, Haiti, and the Dominican
Republic, this species is very variable in the size
and shape of the leaves and in the amount of
indumentum on the branchlets, leaves, and inflo-
rescence. These characters reveal four reasonably
well geographically separated taxa recognized here
as subspecies.
Terminalia chicharronia was based on Chi-
charronia intermedia A. Rich. meg which in
turn was based on Sagra 185 and 281. The spec-
imens at G are the best ones, but there is no
evidence that Richard saw them. In P there is one
sheet with three shoots—two in flower and one in
fruit — which Richard did see. The label says “Her-
barium Richard. No. 185, Combretum sp. nov.,
Guanabo, Marzo 1829, Coll. R. de la Sagra." The
two flowering shoots are here designated as lec-
totype because in G there is a note from Sagra
saying that no. 185 was sent first and was flowering,
and no. 281 was sent later (both March 1829) and
fruiting. This typification fixes subsp. chicharronia
as the subspecies with densely pubescent to rufous
tomentose leaves with strongly raised venation. It
occurs most commonly in eastern Cuba (prov. Ori-
ente), where it is sympatric with the closely related
T. eriostachya A. Rich., which differs by having
larger flowers, longer inflorescences, and glabrous
styles. Terminalia maestrensis Bisse is here con-
sidered to be a synon

2. Ramatuella Kunth
This former genus was revised by Exell & Stace
1963), who recognized six species. Subsequent
collections have shown that this should be reduced
to three. Moreover, although Ramatuella is still
recognizable by the combination of characters out-
lined by Exell & Stace, it seems far better reunited
with Terminalia, as its distinction is based on only
one of several combinations of characters found in
Terminalia. Accordingly, we reduce it to sectional
—
status.

Terminalia kuhlmannii belongs to sect. Dip-
tera (Eichler) Engl. & Diels, which includes four
other South American species. Of these, 7. janu-
ariensis DC. and T. guyanensis Eichler have much
larger glabrous fruits; T. argentea C. Martius has
ovate leaves, and leaf lower surface and fruits
usually tomentose at least when young; and T.
phaeocarpa Eichler has larger leaves usually acute
to rounded at apex with eucamptodromous vena-
tion, and usually glabrous fruits. Terminalia kuhl-
mannii most closely resembles T. guyanensis, but
this is geographically remote and differs addition-
ally in its narrower leaves with less conspicuous
venation and shorter inflorescence

Engler wrote the name “Uleana” on the sheet
at B but did not publish it. Also written on the
sheet is the idea that the species is related to T.
argentea. The new species belongs to sect. Aus-
trales Engl. & Diels, itself close to sect. Diptera,
which contains T. argentea. Of the species in sect.
Australes, T. uleana differs from T. australis Cam-
bess. and T. reitzii Exell in fruit shape and from
T. triflora (Griseb.) Lillo by having wider leaves
and wider fruits with a differently shaped wing.
The fruit wing of 7: uleana is often curved down-
ward (retrorsely), and this character is diagnostic;
a third rudimentary wing is often present. The
species has not been found since 1889.

tion (Wilbur, 1988). Wilbur argued that the orig-

INTRODUCTION AND TAXONOMIC HISTORY
The generic placement of the species here known
as Solanum allophyllum (Miers) Standl. has long
been a source of confusion. Various workers have
placed this species in Solanum, Cyphomandra,
and Bassovia. It was first described as Pionandra
allophylla by Miers (1854) in Seemann's Botany
of the Voyage of the H.M.S. Herald. Pionandra,
erected by Miers in 1845, is synonymous with
Sendtner's genus Cyphomandra, created a few
months earlier (Sendtner, 1845). Accordingly, P.
allophylla was transferred to Cyphomandra by
Hemsley in 1882. Standley transferred Cypho-
mandra allophylla to Solanum in 1927 without
explanation.
Georg Bitter, unaware of Miers's species, in-
dependently described the species as Solanum el-
lipsoideibaccatum Bitt. in 1913. He noted that
the tapered anthers with small terminal pores re-
semble those of Solanum subg. Leptostemonum
(Dun.) Bitt. but surmised that his species probably
represented a new section of Solanum. In 1914,
Bitter received specimens illustrating the lobed
leaves that often occur on the lower branches in
this species. He emended his original description
to include these lobed leaves and described a new
variety, var. ficilobum Bitt.,
hibiting almost exclusively lobed leaves.
from a specimen ex-
Pittier
(1947) later transferred Solanum ellipsoideibac-
catum to the genus Bassovia, an error that Hun-
ziker (1969) later corrected. Solanum ellipsoi-
deibaccatum and its variety ficilobum are regarded
here as synonyms of the earlier name Solanum
allophyllum (Miers) Standley.
Standley's placement of the species in Solanum
was followed in the older literature (Morton, 1944;
1965; Standley, 1928), but
more recent workers have interpreted it as be-
longing in Cyphomandra (Bohs, 1986, 1988; Child,
1984; D'Arcy, 1973). All those who have included
the species within Cyphomandra have noted its
Romero-Castaneda,
atypical anther structure, but placed it in. Cy-
phomandra on the basis of other similarities. Child
(1984) called attention to its anomalous features

Why has the generic placement of this species
been so uncertain? Though $. allophyllum differs
from Cyphomandra in a number of morphological
characters, it has been considered as a Cypho-
mandra because, at least superficially, this species
shares with Cyphomandra the very features that
have been used to distinguish Cyphomandra from
Solanum. Both S. allophyllum and Cyphomandra
have: 1) a growth habit characterized by a single
erect trunk and a spreading crown of three main
lateral branches, 2) three-leaved sympodial units
with the inflorescences situated mainly in branch
forks, and 3) tapered anthers that are thickened
on the abaxial surface. Growth habit and branching
pattern have been recently proposed as new char-
acters that distinguish Cyphomandra from Sola-
num (Bohs, 1986). Anther structure traditionally
separates the two genera (Sendtner, 1845). Herein
| reexamine the morphological features of Cy-
phomandra and S. allophyllum with emphasis on
these three proposed generic characters. New in-
formation about the breeding system and mor-
phology of the chromosomes, pollen, and seeds of
5. allophyllum and Cyphomandra is also com-
pared. These investigations help to ascertain the
generic position of this species and shed new light
upon the critical characters that separate Solanum
and Cyphomandra.
MATERIALS AND METHODS
Morphological studies were carried out using
living plants, and dried specimens from the follow-
ing herbaria: A, BM, C, E, F, GH, K, M, MO,
NY, P, US, and WIS. Voucher information for
greenhouse material is given in the Appendix.
Growth habit is defined by reference to the ar-
chitectural models of Hallé et al. (1978). This
system takes into account the dynamic aspects of
plant growth rather than simply considering the
shape of a plant at any one time. Terminology
relating to architecture and branching pattern like-
wise follows Hallé et al. (1978)
Compatibility studies were conducted on plants
growing in pollinator-free greenhouses at Harvard
University and at the University of Vermont. One
to several accessions were grown of each species.
Plants were either selfed or outcrossed, between
accessions and between individuals of the same
accession, by tapping pollen onto a clean glass slide
and rubbing it across the stigma of the female
parent.
For observations of meiotic chromosomes, flower
buds were fixed in Farmer's solution (3: 1 absolute
ethanol: glacial acetic acid) or Carnoy's fixative (6:
3:1 absolute ethanol: chloroform:glacial acetic
acid) shortly after sunrise. Preparations were stained
with 1-2% acetocarmine and squashed in Hoyer's
solution. Root tips for mitotic chromosome obser-
vations were pretreated for up to 24 hours in a
saturated solution of paradichlorobenzene at ap-
proximately 4?C, then fixed in Farmer's solution
for up to 24 hours. Root tips were then stored in
70% ethanol until use, hydrolyzed in 1 N HCI for
10 minutes at 60°C, and stained as above
Histological preparations of anthers were ob-
tained from flowers that had been fixed in FAA,
dehydrated in an alcohol series, embedded in Para-
plast, sectioned, and stained with safranin/ fast
green.
Pollen measurements were made from fresh pol-
len samples obtained from greenhouse plants. The
grains were shaken into a mixture of 1-2% ace-
tocarmine and Hoyer's solution and allowed to stand
for exactly 10 days before measurement. Mea-
surements of the polar and equatorial axes on 30
grains per sample were made from a 400 X camera
lucida projection onto a Zeiss ZIDAS digitizer. Pol-
len diameter was measured on stained grains only,
and was taken as the distance between the inner-
most layers of the pollen grain wall. Pollen volume
was calculated using the formula for the volume
of an ellipsoid, V = rPE*/6, where E is the equa-
torial diameter and P is the polar diameter. An
analysis of variance revealed no significant differ-
ence between equatorial diameter as measured in
polar and equatorial views, so P and E were mea-
sured in equatorial view only.
Pollen samples for scanning electron microscope
SEM) photos were taken from dried herbarium
material. The grains were mounted on the stub
with double-stick tape and coated with gold-palla-
dium. Fresh pollen from greenhouse plants that
was critical-point dried and coated appeared col.

Cyphomandra. Solanum allophyllum has been
collected from a single site in Honduras and is
more abundant from Costa Rica and Panama
through northwestern South America (Fig. 1).
though the plants are found in a variety of habitats,
in Costa Rica and Panama the species seems to
grow in drier sites than Cyphomandra species,
which are almost always mesic-forest dwellers. No
herbarium collections of this species from Costa
ica or Panama were made in the months of Jan-
h, the dry season in these regions (Coen,
allophyllum persists by losing its leaves during the
dry season and perennating via its roots or larger
shoots, but further field studies of this species are
needed to ascertain its phenology. In the green-
house the plants flower and fruit within five months
from planting. This generation time is much shorter
than most cultivated cyphomandras, which often
take several years to reach reproductive age. Sola- j.
num allophyllum is a weakly woody shrub that
rarely grows over 1.5 m tall (Fig. 2), in contrast
to the majority of Cyphomandra species, whic
develop abundant secondary xylem and may reach
heights of up to 10 m.
e subcordate to truncate leaf bases of 5. al-
lophyllum are decurrent along the petiole (Fig. 3).
The leaves of Cyphomandra usually have cordate
or less frequently truncate bases; decurrent leaf
bases occur only in C. fragilis Bohs.
The inflorescences of S. allophyllum are un-
species of Cyphomandra. In the
presumably also in the field, the fruits fall to the
branched and bear 4-6 flowers on short pedicels
4-6 mm long. Those of Cyphomandra can be
branched or unbranched, typically bear more than
10 flowers, and have pedicels longer than 10 mm.
e shape of the corolla of S. allophyllum can
best be described as rotate-stellate (sensu Correll,
1962): fairly long corolla lobes are present, but
these are connected at the base by abundant in-
terpetalar tissue that is plicate in the bud (Fig. 4
This type of corolla is often seen in Solanum subg.
Potatoe (G. Don) D'Arcy. In contrast, the corolla
f Cyphomandra has various shapes, but never
rotate-stellate or plicate.
Solanum allophyllum produces some of the most
distinctive fruits in the Solanaceae. At maturity,
they are glabrous and white or occasionally orange
mottled with green or purplish markings. The fruits
are ellipsoidal or oblong in outline, and are laterally
compressed and appear elliptic in cross section (Fig.
fruits differ from those of all species of Cypho-
mandra in color and shape, and the seeds are much
smaller and more numerous than those of any

persal agents are unknown, but they may be at-
tractive to birds or bats.
ARCHITECTURE
The distinctive growth habit or shape of S. al-
lophyllum and many species of Cyphomandra is
a conspicuous feature that allows the plants to be
recognized easily in the field. In terms of archi-
tecture, however, Cyphomandra and S. allo-
phyllum are similar only in the initial phase of
their growth (Fig. 6). In both, the seedling axis
produces a single orthotropic, or upright, trunk
with the leaves spirally arranged in a 2/5 phyl-
lotaxis. This trunk ends with the production of a
terminal inflorescence. Usually three plagiotropic,
or horizontal, shoots then elongate from axillary
buds located just below the inflorescence to produce
a spreading crown (Fig. 6A, D). Further branching
within the crown occurs by sylleptic elongation of
axillary shoots immediately below the successive
terminal inflorescences; thus the crown is composed
of a series of sympodial units where all the flowers

and fruits are borne. Beyond this, Cyphomandra
and S. allophyllum diverge in their architecture.
In Cyphomandra, after continued sympodial
rowth and numerous episodes of flowering and
fruiting, the plagiotropic branches begin to senesce.
new trunk then arises proleptically from an ax-
illary bud on the old trunk below the branch tier
and continues orthotropic growth until another ter-
minal inflorescence and branch tier is produced.
In this way, the main axis is composed of successive
sympodial trunk modules bearing spatially and tem-
en separated reproductive crowns (Fig. :
C). I have seen this architecture in at least six
species of Cyphomandra, and it is probably wide-
spread in the genus. [n contrast to Cyphomandra,
5. allophyllum does not produce successive trun
modules. The whole plant in 5. allophyllum is
therefore equivalent to a single structural unit of
the Cyphomandra growth form.
The architecture of Cyphomandra described
above occupies an intermediate position between
Prevost's and Nozeran's models in the scheme of
Hallé et al. (1978). Both models have an ortho-
tropic sympodial trunk and tiered plagiotropic

branches. In Prevost's model both the trunk and
plagiotropic branches generally have spirally ar-
ranged leaves, whereas in Nozeran's model the
orthotropic and plagiotropic branches have highly
contrasting leaf arrangements, usually with spiral
phyllotaxis on the trunk and distichous phyllotaxy
on the branches. Plagiotropy of the branches in
Nozeran's model is perpetuated if a crown branch
is independently propagated, whereas in Prevost's
model the plagiotropy of the crown branches is
usually lost when they are separated from the trunk.

for comparative mor-
fore, although the leaf arrangement on the plagio-
tropic shoots is not distichous, the crown branches
show pronounced dorsiventral symmetry in con-
trast to the radial symmetry of the spirally arranged
trunk leaves. Cuttings taken from the crown region
of C. betacea, C. diploconos, and C. diversifolia
produce lower, bushier plants than those taken
from the upright axes (Fletcher, 1979; pers. obs.),

so these species apparently exhibit the inherent
nature of plagiotropy in the crown branches char-
acteristic of Nozeran's model. At least until an
accurate interpretation of leaf arrangement on the
plagiotropic shoots is available, it is probably best
to consider Cyphomandra as being intermediate
between Prevost's and Nozeran's model
The architecture of S. allophyllum does not
strictly conform to any of the models defined
Hallé et al. (1978). It most closely resembles Leeu-
wenberg's model, which is exhibited by several
n. ies of Solanum and Capsicum (Hallé et al.,
1978). However, in Leeuwenberg's model, all the
axes are orthotropic and equivalent, whereas in S.
allophyllum there is evident differentiation be-
tween the trunk and crown branches. Perhaps the
yest way to characterize the architectural form of
5. allophyllum is to consider that it may have been
derived by "fragmentation" from more woody
counterparts with multiple trunk modules, such as
those seen in Cyphomandra. Fragmentation oc-
curs when only a portion of the original tree model
is expressed, and is commonly seen in herbaceous
relatives of woody plants with more strongly de-
veloped trunk modules. Should it indeed be the
case that the architectural form of S. allophyllum
is related in this way to more extensive tree models,
it may argue that this relatively herbaceous species
has been derived by reduction and fragmentation
from woody ancestors.

BRANCHING PATTERN
Three- to four-leaved sympodial units are the
rule within the crown of nearly all species of Cy-
phomandra (Fig. 7); the only known exception is
C. corymbiflora, which frequently has five-leaved
sympodia. Three-leaved sympodial units are also
characteristic of S. allophyllum. Commonly, the
leaf subtending the renewal shoot is carried up to
a point nearly opposite that of the first leaf pro-
duced on the axillary shoot so that the seemingly
opposite leaves are actually members of successive
sympodial shoot generations. In S. allophyllum
and in many species of Cyphomandra, two renewal
shoots grow out from below the terminal inflores-
cence, thus situating it in a branch fork. This shoot
structure was previously thought to be peculiar to
Cyphomandra (Bohs, 1986), and its presence in
5. allophyllum was evidence supporting the inclu-
sion of the species within Cyphomandra. Members
of Solanum may have one- to many-leaved sym-
podial units, and the inflorescences may be axillary,
extraaxillary, opposite a leaf or leaf cluster, or
rarely in branch forks.
Subtle differences exist in leaf and shoot ar-
rangement within the crown branches of Cypho-
mandra and S. allophyllum apart from the leaves
and branches making up the sympodial shoot struc-
ture. In S. allophyllum, nearly all the axillary buds
of the crown expand into short shoots, giving the

crown a dense leafy appearance. In Cyphoman-
dra, sylleptic growth is restricted to the axillary
buds immediately subtending the terminal inflores-
cences of the sympodial units, the rest of the buds
remaining dormant unless released by pruning or
breaking the tip of the branch. In the greenhouse,
S. allophyllum also undergoes pronounced sea-
sonal reiteration, with expansion of many buds on
the trunk by prolepsis and elongation of the short
shoots of the crown. It is not known whether 5.
allophyllum reiterates in this way under natural
conditions; as already mentioned, it may die back
to the main stem each year and produce a new
plant conforming to the initial model at the begin-
ning of the rainy season.
ANTHER MORPHOLOGY
Tapered anthers with an abaxial thickening oc-
cur in Cyphomandra and S. allophyllum (Figs.
8, 9). Anther shape is not a definitive characteristic
of either genus, however; tapered anthers occur in

though they are common in Cyphomandra, they
are not exhibited in all of its species. There is no
present evidence to indicate that tapered anthers
are homologous within or among these groups. A
more important criterion for distinguishing Cy-
phomandra from Solanum is found in the enlarged
anther connective. In Cyphomandra, the anther
connective is usually very thickened and prominent
abaxially and is sharply delimited from the thin-

thickened in various ways, but they never have a
distinct and abaxially prominent connective.
Solanum allophyllum has a thickened area on
the abaxial side of the anther that has been inter-
preted as an enlarged connective like that of Cy-
phomandra, and has led to the inclusion of S.
allophyllum within Cyphomandra. Microscopic
cross sections through the anther region o
lophyllum and a representative of C mai
C. diversifolia (Dun.) Bitt., show that anther struc-
ture is very different in the two taxa. In Cypho-

the exception of the cultivated tree tomato, C.
betacea (Cav.) Sendtn. In contrast, S. allophy llum
appears to be self-compatible. Neither S. allo-
phyllum nor C. betacea sets fruits in pollinator-
free greenhouses without deliberate pollination. This
indicates that these two species may not be autog-
amous and require a pollinator to transmit self
pollen, or that they may be apomictic and pseu-
dogamous. The style in S. allophyllum is not visible
directly after anthesis, but elongates and emerges
through the anther cone after the anthers dehisce.
Thus, protandry may prevent selfing in this species.
CYTOLOCY
The most compelling evidence for the exclusion
of S. allophyllum from Cyphomandra comes from
chromosome studies. Solanum allophyllum and
nine species of Cyphomandra that have been ex-
amined so far chromosomes (Bohs,
unpublished data; Pringle & Murray, in press). This
chromosome number is common in Solanum and

the Solanaceae in general. However, chromosomes
of the two taxa differ markedly in size (Figs. 10,
11). Investigations of seven species of Cypho-
mandra have revealed that the chromosomes in
this genus are very large, averaging about 8 um
in length with a range of approximately 3 to 14
um (Bohs, unpublished data). DNA amounts as
measured by flow cytometry were among the larg-
est yet known in the Solanaceae (Pringle & Mur-
ray, in press). In contrast, both the mitotic and
meiotic chromosomes of 5. allophyllum range be-
tween | and 2.5 um in length and are thus on the
order of 2.5 to 5.5 times smaller than those of
Cyphomandra.
POLLEN
Pollen grains of S. allophyllum and Cypho-
mandra were examined for potential taxonomic
characters. The grains of 5. allophyllum are tri-
colporate and have exine sculpturing consisting of
very small rounded granules best observed with
SEM (Figs. 12-14). Cyphomandra pollen is also
tricolporate, and most species have granular exine
sculpturing like that of 5. allophyllum, although
several Cyphomandra species (e.g., . pendula
(R. & P.) Sendtn. and C. pilosa Bohs) lack such
granules and have a psilate exine.
Although the aperture type and exine sculptur-
ing show few taxonomically useful differences, the
grains of Cyphomandra and S. allophyllum do
differ somewhat in size and shape. Table 3 com-
pares the pollen dimensions and volume of S. al-
lophyllum and seven species of Cyphomandra. In
the terminology of Erdtman (1952, 1969), all
species of Cyphomandra have spheroidal or pro-
late spheroidal grains, whereas those of 5. allo-
phyllum are more elliptic in equatorial view and
fall into the subprolate shape class. All taxa ex-

amined have small- to medium-sized grains (again
using Erdtman's terminology), but those of 5. al-
lophyllum are much smaller than any species of
Cyphomandra. Cyphomandra grains have vol-
umes about 2.5 to more than 10 times larger than
those of S. allophyllum.
SEED SIZE
The seeds of S. allophyllum are substantially
smaller than those of any of the Cyphomandra
species examined (Table 3), ranging from about Y,
to Y, the size of Cyphomandra seeds.
DISCUSSION
There are numerous differences in ecology, phe-
nology, and morphology between 5. allophyllum
and Cyphomandra, but these alone do not permit
an unequivocal placement of the species in either
Solanum or Cyphomandra. Architecture and some
aspects of the branching pattern further differen-
tiate S. allophyllum from Cyphomandra, but again
not enough to place the former definitively in either
genus. A problem with the use of these characters
is the wide range in architecture and branching
pattern seen in Solanum. It looks as if these two

characters cannot be as useful in distinguishing
Cyphomandra and Solanum as was previously
thought.
In contrast, a consideration of anther morphol-
ogy shows that S. allophyllum does not have a
distinct and enlarged anther connective like that
of Cyphomandra. The anther structure formerly
interpreted as a similarity between it and Cypho-
mandra is now revealed to be a difference that
separates the two taxa. It appears that the presence
of an enlarged anther connective is the most re-
liable morphological criterion for distinguishing Cy-
phomandra from Solanum.
he fact that 5. allophyllum is self-compatible
(SC), whereas the majority of Cyphomandra species
are self-incompatible (SI), is at least an implication
that 5. allophyllum is not a Cyphomandra. Bot

e small chromosomes of 5. allophyllum con-
form to the size reported for species of Solanum
from several different subgenera (Roe, 1967) and
are the best indication that this species belongs in
Solanum. The present study shows that there is a
tendency toward large chromosomes in Cypho-
mandra. This appears to be a very useful character
distinguishing Cyphomandra from Solanum. Fur-
ther studies of chromosome size in the Solanaceae
are needed to determine if this character is con-
sistent in other species. Comparison of genome sizes
between putatively primitive and derived members
of s different plant groups demonstrates that
chang an occur in either direction
(Ob & Khoshoo, 1986). Additional chromosome
studies coupled with morphological data may even-
tually allow us to determine trends in the evolution
of genome size in Cyphomandra, Solanum, and
other solanaceous genera.
The exine sculpturing of 5. allophyllum pollen
also resembles that of Solanum. Anderson & Gen-
sel (1976) and Edmonds (1984) reported similar
granular exine sculpturing in Solanum sects. Ba-
sarthrum (Bitt.) Bitt. and Solanum, respectively.
he occurrence of the same type of exine sculp-
turing in Cyphomandra, however, argues against
the use of this character to distinguish Cypho-
mandra from Solanum. This same type of sculp-
turing also has been reported for other genera
related to Solanum (Basak, 1967) and is probably
the general pollen type of the tribe Solaneae
The pollen grains and seeds of S. allophyllum
are much smaller than those of any species of
Cyphomandra. The pollen dimensions of 5. allo-
phyllum are comparable to some of the smaller
grains reported for Solanum (Anderson & Gensel,
1976; Basak, 1967; Murry & Eshbaugh, 1971),
and the size of the seeds falls within the range for
Solanum (pers. obs.). Pollen or seed size has not
been critically examined as a taxonomic character
separating Cyphomandra and Solanum.
small pollen and seeds of S. allophyllum
may be connected with its small chromosome size.
Bennett (1972) observed that genome size was
correlated with pollen volume, seed weight, and
minimum generation time in various species
herbaceous plants. The association of small chro-
mosome size with small pollen volume, seed weight,
and short generation time in S. allophyllum may
indicate that this correlation also holds in this
species. Further observations are needed to ascer-
tain whether these characteristics are correlated in
other solanaceous species, and whether pollen and
seed size may be used as indicators of chromosome
size.
Affinities of S. allophyllum within Solanum are
problematic. This species is allied with two others,
S. mapiriense Bitter from Bolivia and an unde-
scribed species from Amazonian Peru (Bohs, in
prep.). At present I know of no existing section of
Solanum that accommodates these three species.
They are perhaps best regarded as a new section
of Solanum, as Bitter (1913) suggested. A taxo-
nomic treatment of these three species and a con-
sideration of their placement within Solanum will
appear in a later paper.

ABSTRACT
Three new species of Malouetia (M. bubalina, M. molongo, and M. naias) and one new variety (M. pubescens
var. pep are described. All new taxa are from northwestern South America.
The following novelties have accumulated during
studies of the genus Malouetia, for the most part
in connection with the Flora of the Venezuelan
Guayana.

slender, fusiform, laterally flattened, slightly con-
vex on one side, the ventral surface longitudinally
sulcate, the apical end (i.e., toward the fruit apex)
abruptly converging into a rounded tip 1 mm long,
proximally tapering to a rather blunt end, the apical
tip embedded in a dense mat of long tan hairs,
these attached to the apical half of the seed and

the hairs the testa very thin, stiffly papery, smooth,
glossy, yellowish tan, longitudinally striate; the en-
dosperm forming a leathery case around the em-
bryo; embryo 1.8 cm long, straight, the cotyledons
rather fleshly, ca. 314 times as long as the radicle,
this thick, bent slightly.
Distribution. Colombia, known only from high
forest over white sand at the type locality on the
Rio Caquetá.
The specific epithet refers to the bifid, stout,
curving fruit reminiscent of buffalo horns.
Malouetia bubalina is most closely related to
M. arborea (Vell.) Miers of eastern coastal Brazil,
which also has stout fruits and seeds with an in-
dumentum. But whereas the hairs on the seeds of
M. arborea (Vell.) Miers are woolly and extend in
all directions, those of M. bubalina are straight
and directed toward the base of the follicle. The
new species also differs by having much shorter
pedicels and more ovate corolla lobes.

XA cae Cruz, margen del Rio Atabapo, cerca
del boca del Rio Atacavi, Foldats 36. 54 (NY, VEN).
Distribution. Known only from the type lo-
cality in Amazonian Venezuela near the confluence
of the Rio Atacavi with the Rio Atabapo, on flooded
river banks.
The name comes from molongó a frequent local
name for various Apocynaceae of inundated hab-
itats.
This species most closely resembles Malouetia
gracilis (Benth.) A. DC. from Guyana but differs
by having five cleft weltlike scales constricting the
mouth of the corolla tube. In M. gracilis (Benth.)
A. DC. coronal scales are lacking.

TICODENDRON:
A NEW TREE FROM
CENTRAL AMERICA
Jorge Gómez-Laurito' and Luis D. Gómez P.?
ABSTRACT
Ticodendron incognitum is named as a new genus and species, and the taxonomic position of this tree is discussed.
Despite many years of floristic research in var-
ious Central American countries, new findings still
surprise botanists. Such is the case of a tree, here
described as a new genus and species, which has
puzzled many scientists in the field and in herbaria
and which has produced much correspondence and
discussion. Based on studies of embryology, paly-
nology, wood anatomy, and other features, a new
family of dicots will be published soon for this genus.

Ticodendron
The first known collection was made in this country
at the beginning of the century by C. Werckle
(s.n., US No. 1010451) near San Cristóbal. The
specific epithet refers to its Hamamelidean rela-
tionships.
e new genus and species of Hamamelidean
affinities (Gómez-Laurito & Gómez, 1989) has
prompted much discussion: a possible relationship
to Urticales (e.g., Ulmaceae or Cecropiaceae) has
been suggested. Dilleniales (Wolfe, 1989) and Ro-
sales have also been proposed as possible orders
for Ticodendron. For some time, placement in the
Ulmaceae was favored and our genus does resemble
genera of this family (e.g., Aphananthe Planchon),
but its morphology excludes Ticodendron from
subfamilies Ulmoideae or Celtidoideae. As in the
Ulmaceous genus Zelkova Spach, Ticodendron has
drupaceous fruits and somewhat distichous, pin-
nately veined leaves, but has four hemitropous
ovules, three of which abort very early in devel.
opment. Leaf characteristics suggested to W. Bur-
ger (pers. comm.) a relationship to the Cecropi-
aceae, but our observations revealed a bicarpellate
ovary and two well-differentiated and free stigmas,
among other differences. The dry, hardened fruits
bear a faint resemblance to those of Corylus L.,
and, when we first saw a vegetative specimen, we
thought of Carpinus L., which reaches northern
Nicaragua.
Several genera of Hamamelidales (e.g.,
centron Oliver, Sinowilsonia Hemsley, Altingia
Noronha, and others) show many of the morpho-
logical characteristics of the new plant and suggest
that its true affinities lie within this order, although
its precise placement requires further study.
he venation and marginal teeth of Ticodendron
leaves have been compared and found somewhat
similar to those of fossil Juglandaceae (Hickey, fide
Raven, pers. comm.). Some botanists initially pro-
posed Flacourtiaceae as the proper family.
A possible relationship between Ticodendron and
the Antillean Picrodendron Planchon, based on
the similar appearance of the pistillate flowers, has
been suggested (M. Grayum, pers. comm., 1987)
but 7icodendron has simple leaves and strongly
asymmetrical fruits. Further, its pollen grains are
Tetra-
unusually small and not of the Olfieldia-type, which
occurs in the Euphorbiaceae, where most modern
authors place Picrodendron (Hakki, 1985; Hay-
den et al., 1984; Webster, 1975). Wood anatomy
(Carlquist, in press) and reproductive morphology
(Tobe, in press) point to Fagales.
Ticodendron incognitum forms sparse stands or
is found isolated in the montane evergreen forest
of Central America. In Costa Rica, it usually grows
from 900 to 2,300 m elevation associated with
Aiouea costaricensis (Mez) Kostermans, Phoebe
hammeliana W. Burger, Cedrela salvadorensis
Standley, Eugenia lepidota Berg, and other species.
macho and jaül nazareno (male alder
alder). Both names recall the alderlike habit of
Ticodendron and the purplish tinge of fresh cuts
in most of the trees. Also, it is called duraznillo
and candelillo morado. The wood is used as fire-
wood. It is fine-grained, dries a pale rosy-brown,
takes a high polish, and is harder than that of
Alnus.

A SECOND SPECIES OF
THE AMPHI-ATLANTIC
GENUS ALONSOA
(SCROPHULARIACEAE)
IN SOUTH AFRICA!
Kim E. su
Steiner
ABSTRACT
A second species of the predominantly South American genus Alonsoa has been found to occur in South Africa,
cies in having oil-secreting trichomes in shallow corolla sacs and from the other S
species in its annual habit, dilated filaments, and acuminate, bilobe
d stigma. Flowers of Alonsoa unilabiata are self-
compatible, but are usually out-crossed by Rediviva (Melittidae) oil-collecting bees. Differences between Alonsoa and
Niascia are discussed.
Alonsoa Ruiz & Pavón is a small genus of ap-
proximately 16 species that until recently was be-
lieved to be restricted to the New World (Edwin,
1971; Hilliard & Burtt, 1984; Roux, 1986). It is
concentrated primarily in the Peruvian Andes of
South America but ranges north through Central
America to Mexico and south to Chile and Bolivia;
it also occurs in the Cape floristic region of South
Africa.
Alonsoa is one of seven genera that Bentham
(1876) placed in the Hemimeridae, the others being
Diascia, Diclis, Hemimeris, Colpias,
and Angelonia. Since the American genus An-
elonia is now placed in its own tribe Angelonieae
(Pennell, 1920; Barringer, 1983, 1985), the Hem-
imeridae, with the exception of most species of
Alonsoa, are basically restricted to southern Af-
Nemesia,

The first Alonsoa (A. peduncularis (Kunze)
Wettstein) species discovered in Africa was col-
lected by Zeyher (3485) in the late 1830s from
woody gorges around Uitenhage in the eastern
Cape. The original description (Kunze, 1842) was
prepared from cultivated plants at the Leipzig bo-
tanical garden. The source of that seed was Leh-
mann of Hamburg who obtained it from someone
in South Africa. The original source is uncertain,
but, due to the rarity of this plant, it may well
have come from Zeyher’s collection. No subse-
quent collections of this taxon were made until its
discovery at a second locality in 1985 (Roux, 1986).
Since this second site is far removed from areas
2 past or present cultivation, and since no known
South American species have corolla sacs, Ben-
tham’ s (1876) suggestion that the original speci-
men collected by Zeyher was naturalized from South
America is highly unlikely. Evidently Bentham’s
reluctance to accept Alonsoa as indigenous to South
Africa was due to the unusual amphi-Atlantic dis-
tribution that this would represent.
Out of a combined total of about 4,500 genera
occurring in Africa (including Madagascar) and
South America, a, 115 (2.6%), in-
cluding Alonsoa, are restricted to these subconti-
nents (Thorne, 1973; Hilliard " Burt 1984). O
these, only seven (0.2% of the full total) occur in
the Cape flora of South Africa. Among genera
shared between South Africa and America, Alon-
soa is the only genus presently centered in the
Andes. Except for a few widespread genera (e.g.,

subcontinents were close together. Thus, Alonsoa
must have reached Africa subsequently by long

The presence of a second Alonsoa species in South
Africa strengthens the unusual amphi-Atlantic con-
nection within the genus and warrants an exami-
nation of the distinction between Alonsoa and
Diascia in general, and the taxonomic history,
variation, and reproductive biology of Alonsoa uni-
labiata (Linn. f.) Steudel in particular.
HABIT AND HABITAT
Alonsoa unilabiata is a winter-flowering (July-
October) annual herb with simple to dissected leaves
and pink to orangish pink resupinate flowers with
dark purple-maroon centers. Contrasting with the
dark center is a yellow translucent window or sac
at the base of each lateral corolla lobe.
Alonsoa unilabiata occurs from near the west
coast of South Africa (Elands Bay and Lamberts
Bay), where it is found in loose sands of old sta-
bilized dunes at about 100-200 m, northeast to
the escarpment of the Bokkeveld Mountains
(Nieuwoudtville area), and along the Roggeveld
escarpment from Calvinia south to the northwest-
ern edge of the Little Karoo (Konstabel and Twee-

and Roggeveld, these plants grow primarily in sandy
to clay loam soils derived from shales, except around
Nieuwoudtville where they occur on heavy doleritic
clays. Drége collected 4. unilabiata from the
southwestern Cape near Cape Town in 1836,

from only two localities in the southern and eastern

ecotypes of A. unilabiata associated primarily with
different soil types. The differences between the
ecotypes, involving mainly extent of leaf dissection
and corolla sac shape, are not, however, great
enough to warrant taxonomic recognition.
DISTINCTIONS BETWEEN DIASCIA AND ALONSOA
Corolla morphology of South American and South
African species of Alonsoa is remarkably similar
(Figs. 1-5A, 7). Most obvious is the resupination
which places the enlarged morphologically lower
lip in an upright position. Resupination was over-

pressed material. Diascia species do not have re-
supinate flowers. Coupled with the rather strange
appearance of the corolla caused by resupination
in Alonsoa is the complete split in the corolla
between the lower (morphologically upper) lobes
(Fig. 5B), a character that Kunze (1842; in Hilliard
& Burtt, 1984) erroneously attributed solely to
Alonsoa peduncularis (as Schistanthe peduncu-
laris). This condition is also found in A. unilabiata,
as well as New World species A. meridionalis vd
Kunze and others (pers. obs.; Edwin, 1971). T
Diascia corolla always has a short but distinct us
(i.e., gamopetalous portion) without a split.

cia is the form of the androecium. In Diascia (and
in the related /Vemesia and Diclis) the anterior
lower) filaments twist around the base of the pos-
—
terior (upper) filaments, causing the upper part of
the anterior stamens to be placed in a posterior
position and the posterior stamens to appear in the
anterior position (Hilliard & Burtt, 1984). No such

right; in A. unilabiata (Fig. 5C) and A. pedun-
cularis they project downward. This downward
orientation in 4. unilabiata is caused by the turn-
ing under of the lower (morphologically upper) rim
of the corolla just above the point of filament at-
tachment. Alonsoa unilabiata is set apart from all
other Alonsoa species by its strongly dilated fila-
ments (Fig. 5C-

ally with longitudinal straight (or undulate in A;
unilabiata) furrows (Edwin, 1971). Diascia species
have dorsiventrally flattened embryos and usually
have elaborate wings or cuplike extensions on the
seed coats. The pollen of 4. unilabiata and A.

POLLINATION AND BREEDING SYSTEM
The major difference between South African and
South American Alonsoa species is the presence
in the former of a pair of shallow corolla sacs (Figs.
1-4, 5A, B) containing a dense patch of oil-se-
creting trichomes (trichome elaiophores). These tri-

chomes consist of a two-celled stalk, bearing two

The presence of elaiophores has a direct bearing
on the manner in which these species are pollinated.

collecting bees in the genus Rediviva. Plants grow-

ing in the sandveld near Elands Bay are pollinated
by two small (ca. 10 mm long) undescribed black
species (Rediviva “ruficornis” and R.
while plants on the Roggeveld escarpment from
Grasberg to Sutherland (with the exception of
Nieuwoudtville) are pollinated by a different un-
described species R. “alonsoae” and rarely by R.
“racemosae.” At Nieuwoudtville, plants are visited
R. “racemosae.” In all
EET
“nigra’’),
by R. “macgregori” and
cases, bees place their heads at the base of the
upper (morphologically lower) corolla lobe while
inserting their forelegs into the oil-containing sacs.
The dark central portion of the corolla as well as
the yellow sacs are ultraviolet absorptive and con-
trast with the UV reflective corolla lobes (Steiner,
pers. obs.). The presence of an ultraviolet absorp-
tive region is common in oil-secreting species of
Diascia and Hemimeris and appears to help orient
the bee on the flower (Steiner, in press, pers. obs.).
Specialized scraping and absorptive setae on the
forelegs of the Rediviva pollinators facilitate ex-
traction of the oil, which is transferred to the hind
legs and carried back to the nest (Whitehead &
Steiner, 1985; Steiner & Whitehead, 1988; Buch-
mann, 1988). While probing for oil with its fore-
legs, the bee’s abdomen curls into the cradle formed
by the filaments, causing the anthers to rub against
and deposit pollen on the upper tergites. Pollen is
deposited from the abdomen onto the stigma of the
next flower as the bee repeats this process.
The two Rediviva species at Elands Bay do not
depend solely on 4. unilabiata for oil, but also
visit at least three other oil-producing species in-
cluding Hemimeris sabulosa L.f. and two unde-
scribed Diascia species. On the Roggeveld es-
carpment, with the exception of the Nieuwoudtville
area, 4. unilabiata is pollinated almost exclusively
by Rediviva *alonsoae." Even more unusual,
however, is the apparent restriction of this bee to
the flowers of 4. unilabiata for oil, despite the co-
occurrence of other oil-producing species at each
site. This bee is the only one of 16 western Cape
Rediviva species that is restricted to a single oil
host plant (Steiner & Whitehead, pers. obs.).
Pollinator observations on other Alonsoa species
are lacking. Alonsoa peduncularis occurs sym-
patrically with Diascia patens (Thunb.) Fourcade
and may share the same Rediviva “lepidos” pol-
linator that collects oil from and pollinates that
species, while New World species of Alonsoa, all
of which lack oil-secreting trichomes, are probably
pollinated by pollen-collecting bees. Many of the
American species have large sturdy apically de-
hiscing anthers that form a cone around the style
similar to that found in Solanum. These species
are probably **buzz" pollinated (Buchmann, 1983)
by large Bombus (Apidae) or Centris (Anthopho-
ridae) bees.
The presence of shallow yellow corolla sacs in
some annual Diascia species (D. capensis (L.)
Britten, D. diffusa (Thunb.) Benth., D. cardiose-
pala Hiern, D. elongata Benth. et al.) probably
accounts for the past confusion between Alonsoa
unilabiata and Diascia. It is unlikely, however,
that the presence of these sacs is indicative of a
close relationship between Diascia and Alonsoa
(Steiner, unpublished). Instead, it probably indi-
cates a convergence based on adaptation to polli-
nation by oil-collecting bees (Whitehead & Steiner,
1985; Steiner & Whitehead, 1988). Such unre-
lated parallel evolution of oil secretion has occurred
numerous times in families as disparate as Orchi-
daceae, Iridaceae, Malphighiaceae, Krameriaceae,
Scrophulariaceae, and Primulaceae; in unrelated
orchid genera such as Oncidium and Disperis; and
among unrelated Scrophulariaceae, such as Cal-
ceolaria, Bowkeria, and Diascia (Vogel, 1974,
1986; Simpson & Neff, 1981, 1983; Steiner,
1987).
Alonsoa unilabiata is self-compatible, as are
other species in the genus, including 4. pedun-
cularis (Roux, 1986) and A. meridionalis (pers.
obs.). Both of these last-mentioned species readily
self-pollinate, and 4. peduncularis can produce
cleistogamous flowers under certain circumstances
~
pers. obs.). Flowers of Alonsoa unilabiata, how-
ever, self-pollinate only occasionally because of
the spatial separation between anthers and stigma.
Alonsoa unilabiata is most closely allied to
Alonsoa peduncularis, with which it shares the
presence of corolla sacs containing trichome elaio-
phores, characters that must have evolved in Africa
in conjunction with Rediviva oil-collecting bees.
The annual habit, curved and dilated filaments,
and acuminate two-lobed stigma, however, are all
specialized features that set 4. unilabiata apart
from A. peduncularis and the South American
species.
SYNONYMY AND DESCRIPTION
Linnaeus f. (1781), Thunberg (1784), and Ben-
tham (1846, 1876) all failed to realize that Alonsoa
unilabiata (Linn. f.) Steudel has resupinate flowers.
As a result, Diels (1897) described a new species
—
Diascia nutans Diels) for a collection of A. uni-
labiata from the Hantam Mountains near Calvinia.
Discussing the resupinate corolla in his species,
Diels stated that i
to the same result as resupination of the Alonsoa
“evidently this development led
1158
Annals of the
Missouri Botanical Garden
corolla, in fact the convergence developed so far
that without the pits in the throat of the corolla,
our species [D. nutans] would have to be placed
in Alonsoa.” The type of D. nutans was destroyed
in Berlin, but the description and recent collections
from the same locality (Steiner 759) suggest that
Diel's plant must have been 4. unilabiata (Linn.
f.) Steudel.
When Bentham (1836) described D. heteran-
dra he had not seen the type of Alonsoa unilabiata
nor did he see it prior to his treatment of Diascia
in De Candolle's Prodromus (p. 17, 1846). This
may explain why he described Drége's collection
as a new species in the first instance and why he
retained it in his later publication. One of the char-
acters used by Bentham to MEUS. D. heter-
andra was the presence of st . Judging
from the poor preservation of the type as well as
the relative ease with which anthers become de-
tached in fresh material, it is likely that the missing
anthers fell off during preparation and subsequent
handling, since the specimen matches 4. unila-
biata in all other respects.
The type location for Diascia heterandra Benth.,
between Blouberg and Tygerberg, is considerably
south of the main west coast distribution of 4
unilabiata. Habitats near the type locality, how-
ever, are similar to those found around Elands Bay,
where Alonsoa unilabiata can be locally common.
The area between Blouberg and Tygerberg has
been dramatically altered by the spread of urban-
ization and alien acacias, hence 4. unilabiata is
probably no longer there.
Diascia dissecta Hiern is simply a variant of
A. unilabiata related to growth conditions. Its tall
and spindly habit and more narrowly dissected leaves
are typical of plants along the Roggeveld escarp-
ment that grow up through shrubs.

NOTES
A NEW SPECIES OF
ISOETES FROM TERRITORIO
FEDERAL AMAZONAS,
VENEZUELA
While preparing a treatment of the genus /soetes
for the Flora of the Venezuelan Guayana, several
specimens from Territorio Federal Amazonas in
Venezuela were found to represent an undescribed
and distinctive species. This species is described
and compared with other species of the northern
Andes.
The various terms for organs and their character
states follow Hickey (1985, 1986a); terminology
for spore morphology follows Hickey (1986b
dimensional shape characterizations for the ligule,
labium and sporangium follow Radford et al. (1972).

Isoetes vermiculata is known only from stream-
banks on the summit of Cerro Marahuaca of the
Territorio Federal Amazonas in southern Venezue-
la. The species is named for the distinctive wormlike
markings on the proximal and distal faces of the
megaspores.
Isoetes vermiculata is a distinctive element of
the /soetes flora of northern South America. When
fertile, it is most easily identified by its large, ru-
gulate to subretate megaspores and depressed-ob-
ovate sporangia with nearly complete vela. It can
be identified vegetatively by a combination of the
triquetrous (three-sided, with rounded angles) subu-
la, depressed-ovate, auriculate ligular cushion, and
absence of a well-developed labium. The only other
species of /soetes known from this region of Ven-
ezuela is /. triangula, a lowland, seasonal species
having a trigonal (three-sided with sharp angles)
subula, large labium, and pustulate megaspores,
and not having a velum.
Not enough is known about /. vermiculata to
judge affinities with other species in the genus. The
triquetrous subulae and rugulate to subretate mega-
spores of /. vermiculata are, however, similar to
1989.

those of I. novogranadensis, I. andina, and I.
killipii Both /. novogranadensis and 1. killipii
are distinctive in having levigate microspores,
whereas those of /. andina have the plesiomorphic
echinate condition. The large spores of I. vermic-
ulata suggest a hybrid of high ploidy level, perhaps
10x or 12x. Whether this hybridization event took
place when other taxa inhabited the area (perhaps
during the Pleistocene) or whether it represents a
morphologically and geographically distinct seg-
regate population of a more widespread hybrid is
open to question.

brescent or sparsely and minutely puberulent be-
neath (hairs sessile or subsessile, stellate, 4—5-

mm long; branchlets few, short, with flower clusters
sessile toward the apex; vestiture of branchlets and
flowers darkly ferruginous tomentose; bracts not

0.5 mm long, obtuse at apex, rounded and rd

not seen.
Virola steyermarkii has a close affinity with the
officinalis, particularly in the nu-
merous, close secondary nerves and in the narrow,
once-branched male inflorescence, but differs mainly
by having a shorter androecium and androphore
allopatric V.
narrowed from the bottom toward the apex. Fur-
ther, V. steyermarkii is known only from the type
locality in Venezuela, very far from the restricted
distribution of V. officinalis in the Brazilian states
of Bahia and Minas Gerais.
The new species is named in honor of the late
Julian A. Steyermark for his valuable contributions
to the study of the neotropical flora.

A NEW SPECIES OF
CLITORIA (LEGUMINOSAE)
FROM VENEZUELAN
GUAYANA
Two recent collections of a distinctive species
of Clitoria L. (Leguminosae) were discovered while
preparing a treatment of the genus for the Flora
of the Venezuelan Guayana. This species is as-
signed to subg. Bractearia (Mart. ex Benth.) Fantz
sect. Brachycalyx Fantz.
Clitoria comprises 60 species distributed pri-
marily within the pantropical-subtropical belt; 49
species are native to the Neotropics. The genus is
characterized by showy, resupinate, papilionaceous
flowers; infundibular calyx with persistent brac-
teoles at the base; persistent stipules and stipels;
and stalked ovaries with a geniculate, bearded style.
Members commonly bear a pubescence of micro-
scopic uncinate (hooked) trichomes best viewed at
20-30%.
Fantz (1979) circumscribed sect. Brachycalyx
and in 1980 added three new species. Members
are characterized by short tubular calyces with
minute lobes, inflorescences cauliflorous emerging
from denuded nodes preceding the leaves, erect
habits (trees or shrubs), and fruits that become
weakly convex around the seeds and that are con-
spicuously depressed transversely between the seeds.
Species of this section are distributed from Guyana
to central Panama to Ecuador with isolated col-
lections of Clitoria glaberrima Pitt. collected as
far north as southern Mexico.

A NEW SPECIES OF CABOMBA
(CABOMBACEAE) FROM
TROPICAL AMERICA
The genus Cabomba is restricted to the Western
Hemisphere, ranging from the eastern United States
through Central America and the Caribbean to
Argentina. Species of this genus are quite similar
in habit, and few morphological characters are
useful for distinguishing among them. The only
complete taxonomic treatment of Cabomba, by
Norman Fassett (1953), separated species primar-
ily using characteristics of the perianth and leaf
segments. From my fieldwork in tropical America
and an examination of much of the material that
has been collected from this region, some taxo-
nomically significant characters not employed by
Fassett have been discovered. Such characters are
the number of leaves per node, stamen number,
and seed size and shape. Other differences among
taxa for the characters used by Fassett have also
been noted.
In applying this enhanced scrutiny to the ma-
terial included by Fassett in C. piauhyensis Gard-
ner (= C. furcata'), I have become convinced of
the existence of two distinct taxa within this entity.
Typical C. piauhyensis always has whorled leaves
at most or all nodes, commonly six (occasionally
four or five) stamens, and subglobose seeds. This
has been verified using an isotype of Gardner's
original collection (Gardner 2478 US) and is also
readily apparent from the original illustration
(Gardner, 1844). The distribution of C. piauhyen-
sis (C. furcata) includes Brazil, northern Bolivia,
Venezuela, eastern Colombia, the Guianas, Trini-
dad, and outlying populations are known from Cuba
and Costa Rica as well. A second taxon, which
Fassett failed to recognize, has opposite leaves,
often three stamens (sometimes four or five or
rarely six), and slightly larger subglobose to oval
seeds. This taxon occurs from Honduras to western
Ecuador and northern Venezuela and in the Great-
er Antilles. The principal area of sympatry for the
two species is northern Venezuela. The second
taxon is here described, and a key to all members
of Cabomba that occur within its range is provided.

A NEW SPECIES OF
HYPTIS (LAMIACEAE)
FROM THE VENEZUELAN
GUAYANA
While examining collections of Lamiaceae for
the Flora of the Venezuelan Guayana, | encoun-
tered a single gathering of a Hyptis species that
was unfamiliar to me. It was surprising to find a
new Hyptis species at an altitude of 120-150 m
in northern South America.
Although clearly belonging to sect. Hyptis, it
differs from all other known species in its elongate,
interrupted, pseudospicate inflorescences com-
posed of small sessile capitula and situated in the
axils of much-reduced bracts. The new species is
also remarkable for its almost sessile leaves, the
petiole apparently never more than 2 mm long. In
this respect, it recalls H. vilis Kunth & Bouche,
from Central America and northern Venezuela but
differs in floral characters and in leaf shape, and
by having sessile rather than long-pedunculate ca-
pitula. The lack of a ring of hairs in the calyx tube
places H. guanchezii in subsect. Marrubiastrae
Benth., along with H. parkeri Benth., which is also
found in the Territorio Federal Amazonas.
Hyptis guanchezii is named for the collector
and discoverer Francisco Guánchez.

Erect herb to 80 cm high, with slender purple-
tinged stems branching from a central rootstock.
Stems quadrangular with coarse, spreading villous
hairs below, these sparser and more slender above,
the nodes densely tufted with whitish, antrorse hairs.
Leaves 3.5-7.5 X
ing in size above and often shorter than the inter-
.0-3.2 cm, markedly decreas-
nodes, ovate-lanceolate to narrowly ovate with acute
apex and narrowing to a truncate or weakly cordate
base; upper surface of lamina appearing dark green,
villous with scattered rather broad-based hairs, the
veins weakly impressed; lower surface paler, villous
with weak hairs restricted to the rather prominent
veins and margin, glabrous between the veins and
with sunken sessile glands; margin coarsely and
bluntly serrate; petioles 1-2 mm, the upper leaves
often appearing almost sessile. Inflorescence spi-
ciform, 10-15 em long, composed of opposite ses-
sile capitula in the axils of inconspicuous bracts,
the lower internodes usually 5-6 cm long. Bracts
up to 4-6 mm long (the upper bracts shorter),
lanceolate to ovate-acuminate, with broadened base
and somewhat recurved margin, midrib prominent
abaxially. Capitula 10-12 mm diam., with an in-
volucre of narrowly lanceolate, curved bracteoles
up to 5 X 1 mm, these glabrous with the midrib
prominent beneath. Flowers subsessile, surrounded
at base by dense tuft of long, silky, white (pale
brown in herbarium material) hairs. Calyx tubular,
at anthesis ca. 4 mm long, the tube 2-2.5 mm,
glabrous throughout; calyx teeth 1.75-2 mm long,
narrowly deltoid-lanceolate, ciliate with long-acu-
minate apex. Corolla 5-6 mm long, white, the tube
ca. 4.5 mm long; stylopodium absent. Ripe nutlets
not seen.
I acknowledge Julian Steyermark's vision in con-
ceiving the idea of a Flora of the Venezuelan
Guayana, which helped turn my attention to this
floristically rich area with its particularly interesting
phytogeographical patterns in the Lamiaceae.

NEW COMBINATIONS
IN SORGHASTRUM
(POACEAE:
ANDROPOGONEAE)
Nash (1901:71) separated Sorghastrum from
Sorghum Moench on the basis of the reduction of
the pedicellate spikelets to simple pedicels in Sor-
ghastrum. Morphological, anatomical, and cyto-
logical data (Davila, in prep.) support Nash's con-
clusion and reinforce the generic recognition of
Sorghastrum. Davila (1988) recognized 15 Amer-
ican and two African species of Sorghastrum. Two
new combinations in this genus are presented be-
low.

PASSIFLORA MALLETII,
A NEW SPECIES IN
SECTION DECALOBA
(PASSIFLORACEAE)
FROM MESOAMERICA
A number of undescribed species of passion-
flower have been found during a revision of the
Passifloraceae for the Flora Mesoamericana proj-
ect (in press); most of them are in the small-flowered
subgenus Plectostemma Masters. Newly described
here is one such species; it is restricted to Panama
and known from three recent collections.

9-2.1 mm, transversely sulcate with 5-6(-7)
sulci, the ridges slightly rugulose.
Habitat and distribution. The one field ob-
servation by Mallet and the three collections are
from 300—750 m at edges of tropical wet forest
and premontane wet forest, within 25 km of each
other in central Panama. The label on the type
describes the locality as “Pacific slope near divide,
rich wet forest.”
Name. The specific epithet honors the ecol-
ogist Dr. James Mallet, whose specialty is the Heli-
coniine butterflies that feed on Passifloraceae. He
observed this species along the Llano—Carti road
in March 1982, made field notes about the plant,
sent living collections to the University of Texas
at Austin for study (which died), and pointed out
(in litt.) that it was apparently undescribed. He has
made numerous and detailed observations on the
Passifloraceae and realized that a number of species
he encountered were new. By kindly allowing free
access to his field books, his detailed notes have
enhanced the accuracy of the revision for Flora
esoamericana and contributed much to our un-
derstanding of Passiflora.

species from Mexico. From these it is remarkably
distinguished by its mostly unlobed, sharply pointed
leaves, an evidently derived condition. Mallet's field
notes describe the stem as strongly flattened,
suggestive of an unusual phyllotaxy for the family,
ut the dried specimens of the other collectors
appear to be subangulate to partially flattened. The
phyllotaxy is not clear because of deformation of
the stems in drying; both 7; and /j are known in
the related species of this group.
The flowers of the new species are notable for
their short androgynophore and very reduced pet-
als. The sparsely setulose operculum is also dis-
tinctive since the floral parts are only rarely pu-
bescent in this genus. The peduncles are uniflorous
and the flowers are generally crowded on deter-
minate axillary branches, much like its close rel-
ative P. porphyretica.
The seeds of nearly all of the species of sect.
Decaloba are probably bird dispersed, but obser-
vations are few. The label on J. 5. Miller et al.
851 notes "fruit green and being eaten by tou-
canettes." I believe the mature fruits to be purplish
black because in this collection the pericarps turned
black during the process of preparing the specimen,
a phenomenon commonly seen with nearly mature
fruits in this section. In most species of Passiflora
the seeds and arils mature before the pericarp
changes color (pers. obs.). It thus appears that the
irds were eating submature fruit, probably with
sweet mature arils.
The Missouri Botanical Garden, with a grant
from the Jessie Smith Noyes Foundation, gener-
ously funded my postdoctoral research. John Myers
prepared the illustration.

A NEW COMBINATION IN
OCOTEA (LAURACEAE)
Nees (1836) described Nectandra arnottiana
in his Systema Laurinarum and cited only a spec-
imen from the Arnott Herbarium which is now
incorporated in the Herbarium of the Royal Botanic
Garden, Edinburgh (E). This specimen has not been
seen by later botanists working on Lauraceae, who
treated the name incorrectly. Meissner (1864)
treated N. arnottiana as a variety of Nectandra
laurel Nees and stated that he did so only guided
by Nees's description. Mez (1889) accepted N.
arnottiana as a valid species and treated Pleuro-
thyrium chrysothyrsus Meissner as a synonym of
it. He cited only Mathews 3031 (K, BM), the type
of P. chrysothyrsus, under N. arnottiana and
obviously had not seen the specimen from the Ar-
nott Herbarium. I have now seen the Edinburgh
specimen annotated by Nees as N. arnottiana. This
specimen is Mathews 1429. Meissner (1864) rec-
ognized a duplicate of Mathews 1429 in Kew as
an undescribed species and made it the type of his
Pleurothyrium ferrugineum, a species up to now
known as Ocotea ferruginea (Meissner) Mez. But
because the Nees epithet has priority, I transfer it
to Ocotea and present the synonymy for the re-
sulting combination, with the Meissner name in
synonymy.

Excluded from the synonymy is Nectandra ar-
nottiana sensu Mez, non Nees, Jahrb. Bot. Garten
Berlin 5: 402, 1889. Mez based his description on
Mathews 3031, the only collection cited, and his
description of leaves and flowers does not apply to
Ocotea arnottiana.
Ocotea arnottiana is known to me from Andean
cloud forests at 2,000-3,000 m in northern Peru
Bernardi (1975) placed
Ocotea steyermarkiana Allen in synonymy under
O. ferruginea and identified several collections from
and southern Ecuador.
Venezuelan Guayana as O. ferruginea. However,
I consider these Venezuelan collections distinct from
O. arnottiana;
monodaphne steyermarkiana (Allen) van der
their correct name is Rhodoste-
Werff. Similar coriaceous leaves with raised retic-
ulation and a dense tomentum on the lower leaf
surface, which misled Bernardi, occur in several
unrelated, montane species of Lauraceae and are
probably a habitat adaptation. Meissner (1864)
already noted the strong similarity between **Pleu-
rothyrium ferrugineum
and Persea ferruginea HBK; and an as yet un-
described species of Ocotea (not related to O. ar-
EE)
(= Ocotea arnottiana)
nottiana) from high elevation cloud forests in Ec-
uador and Colombia also has these characteristics.
I thank the curator of E for the loan of neo-
tropical Lauraceae.

SISYMBRIUM AREQUIPANUM
(BRASSICACEAE), A NEW
SPECIES FROM PERU
The Brassicaceae (Cruciferae) of Peru were
treated by Macbride (1938) more than half a cen-
tury ago.
changes have since been proposed (see for example,
Al-Shehbaz, 1989a, b; Khanna & Rollins, 1965).
The family as represented in South America needs
to be revised, and many undescribed taxa, partic-
any new taxa and nomenclatural
ularly in the genera Draba L., Lepidium L., and
Sisymbrium L., should be accounted for. The pres-
ent writer is presently working on Draba in South
America as a first step toward achieving that goal.
Sisymbrium arequipanum Al- Shehbaz, named
endemic, is somewhat isolated morpho-
logically from all of the Peruvian species of Sisym-
brium. lt is easily distinguished by having narrowly
linear-lanceolate, remotely dentate basal leaves,
auriculate linear-lanceolate cauline leaves, a few
small flowers, and straight, terete fruits on short,
ascending, straight pedicels. The species resembles
superficially members of Arabis L., but this genus
does not occur anywhere in Central and South
America, and it always has flattened fruits.

REDISCOVERY OF
TETRAMOLOPIUM
ARENARIUM SUBSP.
ARENARIUM
VAR. ARENARIUM
(ASTERACEAE: ASTEREAE)
ON THE POHAKULOA
TRAINING AREA, HAWAII
The initial step in the U.S. Army's Land Con-
dition Trend Analysis Program (LCTA) is to con-
duct a comprehensive floristic and vegetation in-
ventory of each installation. One of the first group
of installations to be inventoried was the Pohakuloa
Training Area (PTA) on the Island of Hawaii, Ha-
waii (Fig. 1). Pohakuloa Training Area is a 44,100-
ha area located in the saddle between Mauna Loa
and Mauna Kea. Approximately half of the in-
stallation is ordnance impact area. Because of the
rough terrain and inaccessibility of much of the
area, only about 4,100 ha are used for infantry,
artillery, and tracked-vehicle maneuvers.
Three endangered plant species have been iden-
tified previously from PTA (Herbst & Fay, 1979):
Haplostachys haplostachya (A. Gray) St. John
var. angustifolia (Sherff) St. John (Lamiaceae),
Stenogyne angustifolia A. Gray var. angustifolia
(Lamiaceae), and Lipochaeta venosa Sherff (As-
teraceae). The species of Lamiaceae were thought
to be extinct until their rediscovery on PTA (Ay-
ensu & DeFilipps, 1978; Herbst & Fay, 1979).
All three of these species occur in a designated
endangered plants habitat (approximately 1,600
ha) on the northwest side of PTA within Kipuka
Kalawamauna (Fig. 1). This kipuka is a vegetated
older lava flow isolated by newer, sparsely vege-
tated, or barren lava flows. The elevation of the
area is approximately 1,545 m. The kipuka re-
ceives about 380 mm of precipitation annually.
During the LCTA survey of the vegetation at
PTA, Tetramolopium arenarium (A. Gray) Hil-
lebr. subsp. arenarium var. arenarium (Astera-
ceae: Astereae) was collected by P. Douglas (Doug-
las 3191) (Fig. 2). Ayensu & DeFilipps (1978)
and Lowery (1986) reported this taxon as presum-
ably extinct because no collections had been made
since the late 1800s. The only previously known
localities for this taxon were Puu Hualalai and
Nohonao Hae (near Waimea) on Hawaii and Kula,
East Maui (Lowery, 1986). A botanical survey
conducted in 1977 as supporting documentation
for an environmental impact statement for PTA
listed T. arenarium (Lawrence Hirai, pers. comm.).
We have been unable to locate any voucher spec-
imens for this reported collection.
Douglas 3191 was collected in the endangered
plants habitat, near the three endangered plant
species. The population of Tetramolopium covers
an area about 200 m by 60 m and is bisected by
an unpaved road. One part of the population grows
about 20 m east of the road. When last observed,
it consisted of 33 robust individuals. The other
portion, with 81 adult plants and 14 juvenile or
seedling plants, occurs approximately 80 m west
of the road. Consequently, the two portions are
about 10 m apart. Fifteen dead individuals were
found in the larger portion of the population. The
cause of death of these plants is unknown. The
occurrence of juvenile or seedling plants indicates
that viable seed is being produced and that envi-
ronmental conditions necessary for seed germina-
tion and seedling establishment occur periodically.
Mature plants were observed flowering in January,
April, and August.
The collection was made in a shrubland domi-
nated by Dodonaea viscosa Jacq., Dubautia lin-
earis (Gaud.) D. Keck, and Sophora chrysophylla
(Salisb.) Seem. A weedy, introduced grass (Pen-
nisetum setaceum (Forssk.) Chiov.) is aggressively
expanding into the area. The Tetramolopium pop-
ulation occurs on a mesic ridge that runs west-
northwest. The soil type at this site is rockland
(rRO) (USDA, 1973).
Tetramolopium arenarium is a member of sect.
Sandwicense Lowery, which is composed of gy-
nomonoecious, upright shrubs with corymbose-
paniculate heads, narrowly funnelform disk corol-
las, and fewer than 15 disk florets per head (Lowery
& Crawford, 1985; Lowery, 1986). This section

also includes T. consanguineum (A. Gray) Hillebr.,
T. conyzoides (A. Gray) Hillebr., and 7. lepidotum
(Less.) Sherff. Of the four species in the sect. Sand-
wicense, two have been considered extinct: T. are-
narium and T. conyzoides (Ayensu & DeFilipps,
1978; Lowery, 1986). The other two species have
extinct infraspecific taxa (Lowery, 1986).
Tetramolopium consanguineum never has hir-
sute or pilose leaves (Douglas 3191 has densely
and evenly hirsute leaves). Tetramolopium cony-
zoides has 1-3 disk florets per head (Douglas
3191 has 5-9 disk florets per head). Tetramolo-
pium lepidotum has glandular punctate leaves
(Douglas 3191 has glandular but not punctate

leaves). The only other member of sect. Sandwi-
cense that occurs on PTA is Tetramolopium con-
sanguineum.
Tetramolopium arenarium is composed of two
subspecies, both presumably extinct: subsp. are-
narium on Hawaii and Maui and subsp. laxum on
Maui (Lowery, 1986). Tetramolopium arenarium
subsp. laxum has open, lax inflorescences, flexuous
pedicels, granuliferous-glandular achenes, and fo-
liage that retains its yellow-green color when dried.
In contrast, T. arenarium subsp. arenarium has
compact inflorescences, densely strigose achenes,
nonflexuous pedicels, and brown foliage upon drying.
Douglas 3191 has compact capitula, densely stri-
gose achenes, nonflexuous pedicels, and brown dried
foliage.
Tetramolopium arenarium subsp. arenarium is
separated into two varieties: var. arenarium and
var. confertum. Tetramolopium arenarium subsp.
arenarium var. confertum has dentate leaf mar-
gins, and involucres 4-6 mm wide and 2-3 mm
long. Tetramolopium arenarium subsp. arenar-
ium var. arenarium has entire leaf margins, and
involucres 6-9 mm wide and 3-5 mm long. Doug-
las 3191 has entire leaves and involucres that are
6—7 mm wide and 4-5 mm long.
We verified our collection by comparing it with
two specimens of 7. arenarium subsp. arenarium
var. arenarium at the U.S. National Herbarium
(US): Mann & Brigham 519, collected at Puu
Hualalai; and Hillebrand 319, which has no lo-
cality information. Both of these specimens were
annotated by Lowery (1986) as T. arenarium subsp.
arenarium var. arenarium. Lowery (1986) stated
the lectotype for this taxon was “Hawaiian Islands:
Hawaii: 1840, U.S. Exploring Expedition (US!,
mixed collection with isotype of T. arenarium subsp.
laxum).” The staff at US could not locate nor has
any record of this specimen; thus, we were unable
to compare our specimen with the lectotype.
Tetramolopium arenarium subsp. arenarium
var. arenarium has no federal or state protection,
because it has been listed as extinct by the U.S.
Fish and Wildlife Service, Office of Endangered
dp pin l (Andy Robinson, pers. comm.).
The U.S. Army, however, has begun a protection
program for this taxon at PTA.
Herbst & Fay (1979) reported that grazing and
browsing by feral animals, cutting for camouflage
by military units, trampling by foot traffic or ve-
hicles, and accidental fires set by hunters and/or
military ordnances may adversely affect the three
endangered plant species found at PTA. Our ob-
servations indicate that the most likely threats to
the endangered plant species and the Tetramolo-
pium arenarium population are from feral animals,
fire, and competition from invading, introduced
plants. We have observed numerous feral sheep,
goats, and hogs in the endangered plants habitat.
Also, the area has been burned (date unknown).
We have not observed off-road vehicular traffic,
foot traffic, or cutting of vegetation for camouflage.
Fencing, removal of all feral animals, reduced use
of the area for training, and continued efforts by
the Army to control fires may help protect these
plants.
We are researching the ecology and population
biology of the endangered species and Tetramo-
lopium arenarium with funding from the U.S.
Army. Propagation of the species is being inves-
tigated as a means of ensuring its survival.
This research was funded by the U.S. Army

port Center (CEHSC-FN), Donald M. Bandel, Chief
of Cultural and Natural Resources. We appreciate

MISCELLANEOUS
CHROMOSOME COUNTS
IN ASTERACEAE,
BIGNONIACEAE,
PROTEACEAE, AND
FABACEAE
Since the publication of my review of the chro-
mosome cytology of the Fabaceae (Goldblatt,
1981a) and the documentation of the original chro-
mosome counts cited therein (Goldblatt, 1981b), I
have made several more counts in the family. These
are reported here with associated collection data
(Table 1). Most of the counts are particularly note-
worthy as they are either the first records for
genera or the first for species.
Counts are also reported for species of Astera-
ceae, Bignoniaceae, and Proteaceae. The signifi-
cance of the counts in relation to the existing cy-
tological record is briefly discussed for each species.
MATERIAL AND METHODS
All counts were made from root tips of germi-
nating seeds, grown in the greenhouse. All seeds
were collected in the wild for this study. Tips were
harvested in midmorning and pretreated in either
0.001 M aqueous hydroxyquinoline for 6-8 hr. at
refrigerator temperature or in saturated aqueous
M-bromonaphthalene for 4 hr. at room tempera-
ture. After rinsing in tap water, the tips were fixed
for 2-3 min. in 3: 1 absolute ethanol: glacial acetic
acid, rinsed again in tap water, and then hydrolyzed
in 10% HCI for 6 minutes at 60°C. Root apices
were squashed in FLP orcein (Jackson, 1975). The
species studied and collection data are listed in
Table 1, in which the diploid numbers are pre-
sented.
DISCUSSION
ASTERACEAE
Of the estimated 48 species of the Old World
and predominantly African Dicoma (tribe Muti-
sieae), only an Indian species, D. tomentosa Cass.,
has been counted, Bhandari & Singh (1977) having
reported 2n = 22. The report here for the southern
African D. schinzii provides additional support for
assuming a base number of x — 11 for the genus,
although x — 9 is almost certainly basic for the
tribe Mutisieae as well as for the entire family
(Raven, 1975; Goldblatt, 1987).
PROTEACEAE
Already counted as Aulax cneorum, the record
here of 2n = 22 in A. umbellata, confirms de
Vos's (1943) report of n = 11 in Aulax. Other
African Proteoideae have x — 12, except Leuca-
dendron, which has x = 13 (de Vos, 1943; Wil-
liams, 1972). 4ulax and Leucadendron are the
only dioecious African Proteoideae, and the kary-
ological data support the contention, based on other
criteria (Rourke, 1987), that dioecism evolved in-
dependently in the two genera and that they are
not closely allied.
BIGNONIACEAE
The count here of 2n — 40 for Parmentiera
valerii, the first record for this species, Is consistent
with the number reported for three other members
f this neotropical genus of tribe Crescentieae
10)
(Goldblatt & Gentry, 1979).
FABACEAE
The count for Zenia insignis, a taxonomically
isolated and apparently primitive member of Caes-
alpinieae—Cassieae, accords with the putatively ba-
sic chromosome number for the tribe, x = 14
(Goldblatt, 198 1a).
In Papilionoideae, 2n = 20 in the monotypic
Graziodendron is consistent with other numbers
recorded for Dalbergieae, including the closely re-
lated genus Andira (Goldblatt, 1981a). Pterocar-
pus, also considered closely related (de Lima, 1983)
probably has x = 11, but at least two species also
have n = 10 (Goldblatt, 1981a). The diploid num-
bers for the previously uncounted Chadsia and for
Lonchocarpus pycnophyllus, 2n = 22, accord

with the presumed base number for Tephrosieae,

counted genus Poissonia (tribe Robinieae), P. hy-
poleuca has 2n — 32, and this species appears to
be oe Base number in Robinieae is either
= nies or 10, but dysploidy is evident in the tribe,
and 6 recorded in some genera
— 9, 8,
C nie: 1981a). A base number of x = 8 seems
likely for Poissonia, a hypothesis consistent with
the patterns of karyological variation in the tribe.
Basic chromosome number for Desmodieae is
ipee x = 11, but at least Pycnospora and the
one species of Brya previously counted have n —
10 (Goldblatt, 19812). This first count for B. buxi-
folia is consistent with the earlier record for the
genus.
1188
Annals of the
Missouri Botanical Garden
Basic number for Phaseoleae is x — 11,
number also probably basic for all eight subtribes
(Goldblatt, 1981a). The counts here for Neoru-
dolphia (Erythrininae), a monotypic genus previ-
ously uncounted, and Neorautanenia brachypus
(Phaseolinae) are consistent with this pattern. The
count for Neorudolphia is of interest in view of
its possible relationship with the large genus Ery-
thrina, whic
er in Neorudolphia confirms data from other
as x — 21. The chromosome num-
sources that it is probably not closely allied to
Erythrina
My count of 2n — 20 in Pachecoa prismatica
(Aeschynomeneae-Stylosanthinae), cited by Nor-
man & Gunn (1985), accords with the base number
of x —
the nnus four genera of the subtribe. Arthro-
m is uncounted while Chapmannia has x —
1 “Goldblatt. 1981a, b). The last-mentioned two
genera are most closely allied to Pachecoa (Nor-
man & Gunn, 1985).

LEPIDIUM BOELCKET AND
L. JUJUYANUM
(BRASSICACEAE),
NEW SPECIES FROM
JUJUY, ARGENTINA
Several new taxa and nomenclatural changes
have been published (Al-Shehbaz, 1986; Boelcke,
1964, 1984, 1986) following the treatments of
Thellung (1906) and Hitchcock (1945) on the South
American species of Lepidium. The genus, which
is represented in South America by probably more
than 50 species, is in need of a comprehensive
study. Species boundaries within certain complexes
are artificial, and the variation of many taxa is
poorly understoo
he two novelties described below were initially
sent to Professor Reed C. Rollins for identification.
I am grateful to him for making them available for
my study. Each of these is known only from the
holotype.

ilios: nigella, compressa, exalata, ca. 3 x 1.5 mm.
Perennial herbs, with a woody, unbranched cau-
dex 1-2 cm diam. Stems few to several from the
caudex, ascending to subdecumbent, villous, 6-15
cm long. Basal leaves spatulate, petiolate, obtuse
to rounded at apex, attenuate at base, earlier ones
entire, later ones dentate to subincised, 1.6-4 cm
long, 3-8 mm wide, the blades glabrous or hirsute
along the midrib; petioles flattened, densely hirsute,
1-2.5 cm long. Cauline leaves few, spatulate to
oblanceolate, entire, attenuate and subsessile at
base, 5-11 mm long, 1-3 mm wide. Inflorescences
densely flowered, ebracteate, corymbose racemes,
considerably elongated in fruit; fruiting pedicels
ascending, densely puberulous to subhirsute, 5-7
mm long. Sepals oblong, persistent, glabrous, some-
what leathery, 2-2.5 mm long, 1.2-
with a conspicuous white margin 0.2-0.5 mm wide,
1.5 mm wide,
repand to suberose in the distal half. Petals spat-
ulate, white, rounded at apex, attenuate at base,
3-3.2 mm long, 0.7-0.9 mm wide. Stamens 2;
filaments white, 2-2.5 mm long; anthers oblong,
0.7-0.8 mm long. Fruits narrowly elliptic to ellip-
tic-oblong, conspicuously flattened, glabrous, wing-
less, obtuse to obscurely notched at apex, 6-7 mm
long, 3-3.6 mm wide; style exserted, 0.6-0.8 mm
long; stigma entire, wider than the style. Seeds
oblong, blackish, wingless, flattened, ca. 3 x 1.5
mm.
Lepidium boelckei, which is named after Dr.
Osvaldo Boelcke, authority on the Argentinian
Brassicaceae and author of several species of Le-
pidium, is easily distinguished from all of the pe-
rennial South American species in having narrowly
elliptic fruits 6-7 mm long, persistent sepals with
a broad white margin, conspicuous styles well-
exserted beyond the apical fruit notch, and sub-
decumbent stems from a thick woody caudex. The
Brazilian L. grandifructum C. L. Hitchc. is the
only other South American species with fruits as
large as those of L. boelckei. However, the former
is a robust, erect plant with caducous sepals, six
stamens, and included styles. Evidently, the two
species are unrelated, and L. boelckei has no close
relatives.

Lepidium jujuyanum, which is named after
Province Jujuy, Argentina, belongs to the L. mey-
enii Walp. complex, of which the component species
are perennials with exserted styles. The new species
is easily distinguished from all the South American
lepidiums in having long-petiolate leaves with vil-
lous, crenate-serrate blades and straw-colored, con-
spicuously winged, persistent petioles, strongly di-
lated filament bases, perforated septa, and rhomboid
fruits with exserted styles.
