MALPIGHIACEAE Juss.
Reference: Niedenzu, Pflanzenreich IV. 141. Hefte 91-94. 1928.
Lianas or sometimes erect shrubs, rarely arborescent, always
Lnmore or less suffruticose, the usually opposite mostly petioled and
I? entire pinnately nerved leaves abundantly glanduliferous, the tri-
chomes most often brachiate, bifurcate. Stipules usually present,
inmost often small, variously placed. Inflorescence terminal or
2: axillary, simple or compound, rarely reduced to a single flower, the
^ articulate peduncles mostly bracted and bibracteolate. Flowers
hermaphrodite, rarely apetalous, the 5 sepals rarely connate at
v base, nearly always with 1 (2) glands, the 5 petals commonly clawed
r and diverse, often crenulate to ciliate. Stamens 10 and all fertile
or ordinarily in part staminodia, the filaments usually more or less
| connate, the 3 styles usually free, obtuse, capitellate or dilated at
tip, sometimes acute, the gynaecium usually 3-carpellate. Ovules
solitary, pendulous. Fruit 3(2-4)-parted, capsular, drupiform or
nuciform, often more or less, and irregularly, winged or samaroid,
and simulating some Sapindaceae. Seeds without endosperm.
The family is known particularly for the highly narcotic alkaloid
furnished especially by Banisteria caapi, which see below; omitted
is the related Amazonian (Para) genus Cabi Ducke, Arquivos Serv.
Florestal 2, No. 1: 13. pi. 1. 1943, perhaps also narcotic but unique
because the flowers are yellow, fruits not winged.
My indebtedness to the kindness of Dr. Jose* Cuatrecasas in
listing most of the negative numbers is noted with thanks. In most
instances I did not see the prints.
Fruit more or less winged, usually 3 samaras affixed to an elevated
torus; plants infrequently suberect, rarely entirely upright.
Samaras laterally (and variously) alate, dorsally merely carinate
or shortly alate unless in Diplopteris.
Sepals (as bracts) spathulate to oblong or oblanceolate, the
aestivation valvate; styles curved 4. Diplopteris.
Sepal aestivation quincuncial; styles nearly straight unless in
Hiraea. ^

786 FIELD MUSEUM OF NATURAL HISTORY— BOTANY, VOL. XIII
Ashy pilose-sericeous liana, usually only the leaves glabrate in
age above; stipules subulate, barely 1 mm. long; petioles stout,
7-20 mm. long, evanescently glandular; leaves ovate-elliptic (often
broadly elliptic in Peru) or oblong, acute or obtuse at base, acuminate

Apparently very much like M. sepium but the pubescence
typically velutinous (however the leaves are sometimes, it seems,
glabrate in Peru), the bractlets provided with a large gland, the
petals roseate or lilac (sulphureous, subsp. thianiha), and the stamens
rather unequal with often oblongish anthers. — The var. fusca Sus-
senguth, Repert. Sp. Nov. 42: 46. 1937 differs from the type, accord-
ing to its author, in the brown-velvety stems and petioles, the leaves
to 12 cm. long, 11 cm. wide with much looser pilosity and with 2-4
glands beneath about 1 cm. remote from the margin; much more
aberrant, and perhaps not correctly placed here, is Klug 25 with
strigose pubescence, sparse on the leaves but with the inflorescence
(including glands, flower color and anthers) of M. cordifolia rather
than of M. sepium, to which I at one time referred it, with query;
it may be designated M. cordifolia var. peruviana Macbr., var. nov.,

M. loretensis differt stipulis vix 1 mm. longis, petiolis ad 12 mm.
longis fere 2 mm. crassis, foliis oblongo-ellipticis apice breviter
obtuseque acuminatis 13 cm. longis, 5-6.5 cm. latis, basi biglandu-
losis; pedunculis paniculorum 4-5 cm. longis, minute puberulis,
floriferis vix 2 mm. longis, haud incrassatis; pedicellis circa 15 mm.
longis; petalis suboblongis 4 mm. longis tenue carinatis; staminibus
inequalibus ad 2 mm. longis. — It is for convenience that I compare
this liana here (perhaps new only to Peru), as its relationship is
probably elsewhere; the long-peduncled leafless axillary and terminal
panicles, the latter about 1.5 dm. long and broad, are further distinc-
tions, but without fruit its generic position — for that matter, of
course, its family position — can only be surmised. The collector
noted the flowers as pale lilac and yellow.

persistent, cartilaginous margined, 2 mm. long; petioles slightly
canaliculate, eglandular, to 9 mm. long; leaves ovate, rounded at

lustrous above, plane, equally membranous to margin, the 5-6
nerves and reticulation equally prominent both sides; racemes to
12-flowered in terminal sessile leafy panicles about 6 cm. long,
these leaves lanceolate, sparsely pubescent both sides; raceme
peduncles 1 cm. long or so, densely strigose, floriferous peduncles
to 2 mm. long, strongly clavate, medially bracteolate, the small
ovate bracts and bractlets pubescent; flowers about 12 mm. wide,
sepals oval, rounded, 3 mm. long, 8-glandular; petals yellow, gla-
brous, 4 mm. long, wing-carinate; anthers glabrous; anterior style
truncate, 2 posterior uncinate; ovary hirsute; samara glabrous,
obovate, nut ovoid, the areole linear-lanceolate, 5 mm. long, 1 mm.
wide; lateral wings continuous at base, distinct at apex where both

are incised into lanceolate or ovate lobes, 15 mm. broad and high,
margins irregular, the dorsal semiovate, 13 mm. long, 5 mm. wide,
connate at base with lateral, the acute tip much longer than nut,
intermediate wings none. — Allied by author to M. violacea and
M. nervosa, the former with violet or roseate flowers, the petals
scarcely carinate, lateral wings distinct base and apex, these in the
latter continuous, both species with revolute margined leaves,
larger in M. nervosa, and both species with narrower stipules and
bracts.

6-8 cm. wide. — According to the collector the Peruvian plant was
a liana; apparently it is referable here but the related species seems
to be similar. The Williams specimen, unfortunately, like the type,
has undeveloped flowers; therefore Kostermans' treatment of this
plant as a variant marked merely by the leaves slightly sericeous
beneath, while probably correct, remains to be proved. F.M.

Liana, the younger parts including the compressed branchlets
golden tomentose, this indument persisting in the typical form on
the under surface of the leaves; petioles canaliculate above, to
2 cm. long, with 2 obscure glands and 2 stipules at base, the latter
3-5 mm. long and nearly concealed in tomentum; leaves elliptic or
somewhat ovate, rounded at base, shortly apiculate, to 2 dm. long,
more than half as wide, nearly plane, in age smooth and more or
less evanescently puberulent above, the 12, more or fewer, primary
nerves as the subparallel secondary prominent beneath, 2-5 mm.

1-15 cm. long at the node, this about 5 cm. above the leaf-axil and
5-10 mm. below the umbel of around 20 flowers; pedicels at base 1,
at apex 2 mm. thick, to nearly 3 cm. long, the minute thick ovate
bracts and bractlets hidden in tomentum; sepals ovate, basally in-
curved, apically recurved, with 8 glands; petals cordate-ovate,
about 5 mm. long and wide except the smaller glandular-dentate
fifth; styles nearly straight, the obliquely obtuse tip dorsally acute.—
Three related species have been proposed: H. brachyptera Tr. &
PI. 130, Colombian, H. colombiana Morton, Proc. Biol. Soc. Wash.
46: 88. 1933 and H. pachypoda Ndz. 131, of Ecuador; the first has
oblanceolate leaves acute at base, long-acuminate, sericeous beneath,
the second broadly elliptic cordate-based leaves, obtuse or apiculate,
densely strigose beneath, the last subglabrous oblong-elliptic apicu-
late leaves. Under an unpublished name by Morton after the locality
Putumayo and quite possibly occurring within Peru is a nearly
glabrous cordate-based rotund-leaved plant, the peduncles without
the leafy bracts that characterize the other species; in leaf -form it
simulates the following Peruvian collection so closely that Standley
gave it the ined. name. Because of the uncertainty of the relation-
ship and the constancy of the characters concerned, I designate this
liana with rust-yellow flowers only as H. Spruceana var. Mortoniana

bracts, this liana reminds one of T. complicates but with sericeous
petals and no fruits its position has not been discovered. If it is
new it may fittingly record the contribution my friend Julian Steyer-
mark has made toward the completion of this work by his intelligent
selection of the Museum's Peruvian collections for me. Here, since
the specimen is better, I designate the one at the National Museum
as the type.

plant not seen by Niedenzu, who, however, allied it to T. squarrosa,
i.e. T. complicata, as well as to his similar T. boliviensis, which may
be transitional, fide the author himself by way of his var. granatensis.

4. DIPLOPTERIS Juss.
Scandent shrubs characterized particularly by the valvate sepals,
these for known species spathulate, oblanceolate or oblong, tomen-
tulose at least without, the glands connate or free. Umbels 4-flowered
in panicles or corymbs, with large, usually oblongish bracts and
bractlets. Limb of petals about orbicular, usually cochleate, not
entire, more or less sericeous. Stamens unequal, styles more or less
sigmoid. Samaras tardily partly free from pyramidal torus and
with 5 or more scarcely developed to large longitudinal wings, vari-
ously winged, minutely or grossly, the wings ligneous to membranous,
more or less united or distinct, subentire or deeply dentate. — The
name from Greek refers to the double wings. The genus doesn't
seem to be natural as delineated by Niedenzu.

has been proposed to supplant the Linnaean name on the ground
that the latter was based on species now assigned to other genera.
It would seem preferable, especially since there is much preced-
ence, to add the name in the long-used sense to nomina conservanda,
as proposed by Kostermans in Med. Bot. Mus. Rijks Univ. Utrecht
25: 7. 1936. As the name Heteropteris Kunth, based on the type
species of Linnets genus Banisteria, belongs to the nomina con-
servanda and Banisteria L. has been rejected, Intern. Rules ed. 3.
135. 1935, it appears advisable to make Banisteria L., sens. Juss.
a nomen conservandum and Banisteriopsis C. B. Robins, ex Small
a nomen rejiciendum. The action already taken need not preclude
this practical if expedient solution to assure here generic stability,
so clearly desirable, as observed, Field Mus. Bot. 8: 120. 1930.
It is a historic fact that law is subject to change to suit developments.
The name commemorates John Banister, English missionary (circa
1700) and author of the first(?) catalogue of the plants of Virginia.
Banisteria caapi and variants are the source of a narcotic (cf.
under that species below). J. T. Baldwin, Jr., Bull. Torrey Club 73:
282-285. 1946, recorded the 2w-number as 20.
As suggested by J. T. Baldwin, Jr., Bull. Torrey Club 73: 282-
285. 1946, one of the best short accounts of the effects of the alkaloid
which this plant yields is by Louis Lewin under the title "Phantastica,
narcotic and stimulating drugs," New York, 1931, from the German
second edition by P. H. A. Wirth; an extensive bibliography is given
in Pflanzenreich, I.e. 437, including a good paper by Perrot and
Raymond-Hamet, Compt. Rend. Acad. Sci. Paris 1266. 1927 and
one by Lewin, I.e. 469. pi. 186. 1928; cf. also the observations of
G. Klug as reported by Morton, Journ. Wash. Acad. Sci. 21: 487-
488. 1931. Baldwin himself describes well the extreme excitation
of the drug on the nervous system, the user often being transported,
according to all accounts, into a world of pleasurable fantasy.
The drug, variously known as "telepathin," "yagein," or "ban-
isterine," is found in a number of related plants or forms, notably
B. quitensis and B. inebrians, and Baldwin's remarks are quoted
with pleasure: "Though I know nothing of the merits of specific
segregation in this particular aggregate it is my impression that
many groups of tropical plants are over-named through a lack of
understanding of [their] genetic variation. . . . From my own ex-
822 FIELD MUSEUM OF NATURAL HISTORY— BOTANY, VOL. XIII
perience with Hevea I judge that numerous Amazonian species
undergo introgressive hybridization with resultant difficulties for
herbarium studies and that many species in that region are . . .
ecotypes . . . frequently accorded binomial recognition." However
I would add that we would not make this error so often if we would
refrain from giving specific value to characters obviously occurring
in almost infinite variation within a group; specifically, here the
presence or absence of glands is probably a good example.
For convenience the key is artificial; the species are not yet well-
placed or well-known, but the significant characters appear to be
mostly in the styles and fruits; gland development anywhere is
probably variable and it is possible that elongate inflorescences may
bear only one or few fruits at lower nodes, giving herbarium material
a very different aspect in fruit than in flower.

brous, unless B. heterostyla.

Liana, with usually axillary simple or compound corymbs of
rather small yellow flowers borne on slender appressed strigillose
pedicels 6-10 mm. long or the inflorescence said sometimes to be
terminal, leafy; branches typically somewhat strigose or glabrous
in age, more or less lenticellate; petioles 4-8 mm. long; leaves lanceo-
late to elliptic, acutish at the rounded base, more or less acuminate,
often to about 9 cm. long, 4 cm. wide, or in Peru larger, glabrous
or nearly in age and prominently reticulate veined, especially
beneath; flowers 10-14 mm. wide; sepals ovate, the glands large;
stamens and styles glabrous, the latter nearly straight and subequal;
petals glabrous, a little denticulate; samara puberulent especially
about the nut, this somewhat tuberculate or short-alulate, the wing
about 3 cm. long. — Apparently variable or not understood; the Klug
specimen was determined by me as the variety of B. cinerascens
(Benth.) Griseb. because it seemed to match its type, Ule 9477,
which, likewise only in flower, apparently differs only in the smaller
leaves that dried fuscescent, those of Klug being dark and nearly
1.5 dm. long, about half as wide; nevertheless it seems probable
that they represent one entity which may be a variant of B. corni-
folia. Here would key two aberrant specimens that are probably
distinct and perhaps represent an undescribed species: Seibert 2122
from Iberia, Dept. Madre de Dios and Krukoff 5300 from Rio
Macauhan (this det. A. C. Smith, Mascagnia macrophylla); the styles
are basally ciliolate, the samara wing much shorter. For convenience

finally deciduous; leaves broadly elliptic, rounded at base, merely
acute at apex, about 11 cm. long, 6.5 cm. wide, smooth, lustrous,
olive-green above, concolor beneath, soon glabrate both sides except
for a very few trichomes, but the midnerve and laterals prominent
beneath where strigose, the base of the lower ones with 2 large

cence axillary, little longer than 5 cm. in fruit, persistently pubescent,
the umbel peduncles 12-14 mm. long; anterior style 3.5 mm. long,
stouter and longer than the 2 posterior; samara nut early sericeous
becoming strigose, oblong, only one side reticulate-rugose, the other
biseriately alulate or aculeate, the dorsal wing broadly semiobdeltoid,
the wing about 3.5 cm. long, 7 mm. wide at base, 16 mm. below the
tip. — Morton contrasted his species with B. caapi and B. quitensis
as follows: both with minute or small stipules, acuminate leaves,
those of former glabrate, larger inflorescences, anterior style shorter
than 2 posterior, samara wing oblong-obovate or obliquely oblong
and smaller; and further from former, eglandular petioles, well-
peduncled umbels and from latter, glandular leaves. The plant
therefore seems to be an intermediate development but the flowers
are unknown and the taxonomic importance of the characters noted
not proved; certainly even with material accumulated now there
appears to be variable concomitance in the distinctions stressed.
On the other hand there may well be several entities, since Morton
saw 60 specimens.
Morton, I.e. pages 487-488, quoted Klug's notes sent in with
the type (Umbria, Colombia), describing the reported effects of the
drug obtained by an all-day boiling of "yag&' (apparently^, quitensis,
fide Morton), to which is added young shoots and leaves of "oco
yage*" or "chagro panga" (these, fide Morton, much like those of

light yellow flowers on upright twigs with deep green glossy leaves.
The species in Peru is scarcely typical but it seems probably a variant

flowers; cf. Sandwith, Journ. Arnold Arb. 24: 222. 1943. However,

FLORA OF PERU 839
with only 6 fertile stamens (those opposite the yellow petals).
Calyx with 4 sepals biglandular. Petals dentate or fimbriate, at
least the limb, 4 more or less concave. Styles somewhat unequal,
all usually more or less dilated, even foliately, sometimes scarcely
or not at all, sometimes only in part. Stipules none or minute.
Leaves entire to more or less divided, often remote, and usually
with a pair of large glands on the petioles, rarely on the midnerve
beneath. Flowers often in dichotomously disposed umbels, the
peduncles usually longer than the pedicels. — According to Haumann
Merck, Rec. Inst. Bot. Bruxelles 9: 21. 1913, all stamens are fertile
in S. littorale Juss., 511 (which species is nearly S. tomentosum}',
Merck's discovery caused Kostermans to suggest, Pulle, Fl. Surinam.
2, pt. 1: 203. 1936, that this may be found true for other species
when observed living; according to Standley and Steyermark,
Fieldiana; Bot. 24, pt. 5: 493. 1946, only 4 stamens are fertile,
presumably the Guatemalan species. The name, originally "Stig-
maphyllon," refers, of course, to the often foliose style tips and was
"corrected" by Niedenzu to Stigmatophyllon and later to Stigmato-
phyllum.
Development of marginal glands and presence of pubescence on
anthers may not be constant characters, either here or in other
groups. In the entire family there is probably hybridization followed
by apomixis.
The position of S. Kuhlmannii in key ex char, may not be correct.
Styles not foliose, minutely if at all dilated, dissimilar or truncate
or rounded apically, usually one (the anterior) truncate, unci-

Leaves broadly cordate, acute or apiculate, chartaceous; styles
subequal S. primaevum, S. bogotense.
Leaves elliptic, obtuse or rounded, rigid-coriaceous; styles unequal,
two beaked, one attenuate or acute S. peruvianum.
Styles usually subsimilar, two or often all more or less foliose-dilated;
leaves sometimes loosely tomentose beneath.
Mature leaves silvery beneath with a dense appressed indument,
some trichomes long; marginal glands obscure or obsolete;
flowering branches simple to trifurcate, the umbels congested.

after Kostermans, who probably had the characteristic state; the
Peruvian plant, S. maynense Huber, Bol. Mus. Goeldi 4: 575. 1906,
is doubtfully distinct, the author himself only noting: leaves ovate,
sometimes suborbicular, anterior style appendage not at all emargi-

the leaves usually about 10 cm. long, 8 cm. wide, seem to be more

pilose in Peru; samara nut acutely auricled, rugose-cristate or

repand-denticulate. — Name "corrected" by some to "tiliifolium";
the type from Colombia was in fruit, the species floral character
therefore by later authors. None of the Peruvian material seems to
be entirely in conformity but, as the experienced and intelligent
Grisebach observed, species may well be variable and here especially
as regards marginal leaf-glands and degree of nutlet crests; anyway
it is one of the earliest names in a group of poorly understood or not
clearly defined entities. As to the name itself, some authors are
using S. Humboldtianum (DC.) Juss. because of the existence of
the name Banisteria tiliaefolium Vent, 1803. There is, however, no

glabrous, one of the former often dentate, ciliate or fimbriate, the
latter curved and unequal. Ovary glabrous, the styles always free,
simply obtuse or dilated dorsally, the stigmatic surface on the inner

Genus and family named for the first celebrated anatomist, who
was also a physician and philosopher, Marcello Malpighi. He was
one of the first to use the microscope, and many of his discoveries
commemorate his name, as Malpighian layer of the skin, etc.
M. coccigera L. of the West Indies, where known as Singapore
Holly, is probably cultivated; it has 1-2 pink flowers and globose
red fruits. The even better known Barbados Cherry or Escobillo
with 3-8 pink flowers and fruits with thin flesh is M. glabra L.,
which may be Ruiz and Pavon's "ciruela de Fraile" from Chancay
that had "fruit with very sweet and cloying taste, its seeds tasting
like almonds but very nauseating. In order to mature it must be
kept in straw, bran or other matter for several days when it ripens
and becomes, from the slight fermentation, as soft as butter, sweet
with red flesh."

12. BUNCHOSIA Richard ex Juss.
Small trees or erect shrubs, at least the younger parts more or
less pubescent, with entire leaves and axillary, mostly many-flowered
and elongate racemes of small flowers, the bractlets usually with
l(-2) conspicuous gland. Stipules small, linear-lanceolate, acute,
interpetiolar. Calyx glands 10, in part more or less connate, the
sepals not enlarged. Petals and stamens glabrous, the filaments
more or less joined at base as also the styles or these free, obliquely
obtuse or capitellate, the ovary glabrous or sericeous. Pyrenes
2 or 3, smooth. — The name was derived from the Arabic "bunchos,"
meaning coffee, which the pyrenes simulate and which are said to
serve as a substitute. Species (as accepted) very difficult to dis-
tinguish, the key only suggestive. With the approach so usual to
some monographers, key characters are often "destroyed" in varietal
distinctions. While characters of styles and ovary are not always
constant they are usually and thus convenient as any for separating
herbarium material as determined.
Styles soon free or partly so; anther connective, except B. media,
elongate; leaves in general oblong-, elliptic-, or ovate-lanceolate.
Ovary sericeous, 2-celled; connective dark, elongate; leaves said
to vary in glands.
Flowers about 14 mm. broad. . . .B. armeniaca.

nerve, glabrate.
Flowers at most 1.5 cm. wide, the petals not equally glandular.

lanceolate-ovate unless in Peru B. glandulosa.
Ovary pubescent; connective dark (except B. lanceolata), short;
leaves (unless B. lanceolata) usually broadly elliptic or ovate-
elliptic, the glands more or less above base, marginal or
lacking (glands sometimes nearly basal, B. Hookeriana).

stamens exserted medially connate, the anther cells at base of con-
nectives purplish; ovary 2- or 3-celled, densely sericeous, the connate
styles with peltate stigmas; drupe spheroid, more than 1 cm. in
diameter. — The Peruvian plant det. Niedenzu as var. boliviensis
Ndz. has leaves obscurely if at all glandular, ovary 2-celled, drupes
1- or 2-celled, but this Raimondi specimen has yellow flowers and
it might rather be referable to B. angustifolia! However, the species
itself may be found to be a part, properly, of B. Hookeriana. Said

the Weberbauer specimen and the Raimondi one, both from Puno,
are really the same, in spite of the fact that both were determined
by the monographer himself.

shallow fissures (Williams). The Peruvian material is not typical
but too many species have been proposed on differences doubtfully
constant, as variations in bracts, anther appendages and connec-

name for this species, the description as amplified by Jussieu not
disclosing any significant difference. The monographer observed
that it is transitional to the genus Alcoceratothrix Ndz., since like
that the leaves are areolate, stipules long; Sandwith, Kew Bull. 311.

W. H. Wagner, Jr., graduate student, University of California,
kindly dissected one of the two available flowers, preserving it in a
slide which, with his sketches, is filed with the type and I record
my appreciation of his careful work so generously contributed. The
plant simulates B. stipulacea Juss., 762 (Alcoceratothrix Ndz.), in
its subsessile leaves and conspicuous stipules (only one is on the tip
of the flowering branch that constitutes the type). However, no
trichomes have been found other than the subsessile, simply biforked
ones characteristic of all species except B. stipulacea. Sandwith's
suggestion, Kew Bull. 311. 1935, for the retention of the latter in
Byrsonima seems to be correct in view of the discovery of this
apparently intermediate species.
The rather recent death of the collector of this interesting plant
is recorded with regret. Mr. G. Klug was an enthusiastic collector
and able observer for many years near Iquitos; appropriately his
name was given to a number of species discovered by him and, re-
markably, in a region relatively well known.

15. BURDACHIA [Mart.] Juss.
Trees with large chartaceous or coriaceous leaves, the flowers
borne in (l-)3 racemes at the tips of the crowded branchlets. Bracts
and bractlets short, broad and somewhat amplexicaul, each usually
with a large orbicular gland. Petals 5, four with long slender strongly
recurved claws and cochleate incurved blades, the fifth spreading,
less recurved, the blade smaller, nearly plane and with stoutly stiped
glands all around the margin. Stamens glabrous, the filaments
dilated below where coalescent, the connectives enlarged. Styles 3,
incurved before anthesis, apically uncinate, only one seed developing
in the somewhat acute nut. — A similar Amazonian shrub or tree
has been named Glandonia macrocarpa (Benth.) Griseb., 767, charac-
terized by rigid linear caducous stipules, sericeous filaments, fifth
petal glandular toward base, nut cylindric, apically umbilicate.

Branchlet tips rusty sericeous but soon glabrate as the stout
petioles, these 1-2 cm. long, and the coriaceous persisting intra-
petioler stipules, these sometimes glabrate, 5-10 mm. long; leaves
ovate or oval, rounded or obtuse at both ends, usually dull and
nearly glabrous both sides or in one form regularly but sparsely
pruinose-pulverulent beneath, always coriaceous and with the 6-10
or more lateral nerves often so prominent beneath that they are
ribiform; peduncles 1-3 dm. long, the glabrate to sericeous racemes
mostly in 3's and ordinarily about a dm. long; pedicels 6-13 mm.
long with very broad-based acuminate bracts and bractlets; flowers
rose-colored, over a cm. wide, 4 petals concave, the fifth plane and
coarsely gland-margined; anthers 2-3 mm. long with broader ob-
liquely oblong connective exceeding the cells by about 1 mm.;
nut opaque, pyramidal or conoid, finally minutely trivalvate at tip,
about 1 cm. long, nearly as broad at base. — A number of variations,
particularly in shape of leaves, length of petioles (1-1.5 cm.) and
even shape of nuts (as var. sphaerocarpa Ndz.), have been named.

pedicel bracts caducous. Stipules deciduous, subulate. Sepals
connate at base, the posterior much the largest, often spurred. Petals
usually 3, linear or spathulate, anterior mostly larger than the others.
Fertile stamen with subulate or filiform filament at most half as

dark with lustrous golden endocarp, ovoid or oblongoid, 3-celled,
loculicidally 3-valved, 3-winged, each cell with 1 seed winged above
by many long trichomes. — Name has been spelled Vochisia, Vochya
and Vochy, this the native name used by Aublet; Stafleu, I.e. 400,

My indebtedness to Stafleu's work is acknowledged, with especial
appreciation for his intelligent approach and lucid presentation with
inadequate material and information; see his general remarks, I.e.
401 et seq. When I have not entirely followed his taxonomy I have
been prompted by the desire to simplify it if possible, in conformity
with the scope of this floristic compilation.

Herbaceous or ligneous, sometimes scandent, with variously
disposed leaves, the stipules glanduliform or lacking. Flowers
perfect, often irregular, each usually with a bract and two bractlets.
Sepals 5, partly or entirely free, or the two lower united, the inner
two usually much larger and petaloid, as wings. Petals 3, rarely 5,

Herbs, shrubs or trees with usually alternate leaves (these, if
verticillate, commonly the lower) and terminal axillary or infre-
quently extra-axillary racemes of small white or more or less deeply
tinted flowers. Sepals 5, free or the two lower connate, deciduous
or persistent, often three herbaceous or the lower two rarely petaloid
the two inner usually so and, much larger, called "wings." Petals
normally 3, united basally, lower carinate, sometimes 3-lobed, smooth
or with an infra-apical beak or fimbriate crest, the two upper more
or less united to staminal tube or keel; two lateral petals if present
often minute. Stamens 8(6) united into tube split on upper side.
Styles often long with two variously developed stigmas. Capsules
about 2-celled, or completely, sometimes winged, less often fleshy-
coriaceous, the cells, unless the lower, dehiscent. Seeds usually
with highly varied aril, this rarely obsolete. — After Blake, who

Shrubby; branches 1-1.5 dm. long, erect, puberulent; petioles
very short; leaves ovate-lanceolate to elliptic, cuneate at base,

as long as the glanduliform lower. — Chodat contrasts this in his key
with the Mexican P. rivinaefolia HBK. by its "acute" instead of
"cuspidate" leaves (not a clear or impressive difference!); and his
type is probably from Mexico; my remarks under P. deflorata apply
equally here. Illustrated, Chodat, pi. 14, figs. 7-9. F.M. Neg.

it from his key, places it in text next to P. rivinaefolia HBK. of
Mexico, a species belonging to subgenus Hebecarpa (Chodat) Blake,
characterized by sepals all free, wings much larger than sepals,
capsules not subcordate!). Since so much of the material labeled
"Pavon" in herb. Boissier is really Mexican in origin, probably
Sess4 and Mocino, there is no certainty that this plant is Peruvian
and it should have been considered by Blake.

petals much longer than the wings, glabrous; capsule elliptic,
emarginate; seeds triangular, hirsute, aril fleshy, half free, descend-
ing.— Affine P. spectabilis DC. with broader cuspidate leaves; the
narrow leaves suggest the Brazilian P. oxyphylla DC., 77, which,
according to both Bennett and Chodat, should include P. Laureola

lose.— Imperfectly known, perhaps not from Peru, but apparently
the following specimens are referable to it rather than to the related

with similar foliage; the rachis of the former is nearly smooth, the
seed equaled by a linear reflexed aril while the latter has ciliate wings
and seeds with an elliptic, much shorter aril. It also resembles the

often roseate, 1.5-2 mm. long, the subequal outer sepals ovate-
lanceolate, wings elliptic, 3-nerved or nearly 1-nerved, little longer
than the crested keel (2 mm. long); upper petal lanceolate, subretuse;
anthers subsessile on the tube; capsule oblong-elliptic, with a row
of glands each side of septum, subequaling wings; seeds oblong-
elliptic; aril minute, bilobed, appressed, obtuse both ends, slightly
puberulent, 1.2 mm. long (Blake). — Svenson, Amer. Journ. Bot. 33:
458. 1946, has noted that Chodat's illustration of the seed of P.
alopecurus matches that which he shows for the species of St. Hilaire,
both with aril only one-tenth length of seed, the author's key
character for his species, "aril one-half length of seed" evidently
an error. Since Svenson found seeds 1.5 mm. long in specimen from
Colombia (det. Blake, P. leptocaulis) and seeds averaging 1.1 mm.
long in P. alopecurus, from general type region (Chanduy), it is
probable, as he states, that the latter is no more than a small-seeded
variation of P. leptocaulis which in turn seems not clearly separable
from the Brazilian plant. According to Wm. Hunter (cf. Svenson)
this "purple flowered grass" appears only in occasional years. Illus-

With the author's approval I have compiled this for him; the
wording is thus, for convenience and in the interest of uniformity,
often mine and of course I take responsibility for omissions and
mistakes. I take great pleasure in having Dr. Ferreyra as a con-
tributor and hope that Peruvian botanists will have the opportunity
to take an ever greater part in the study of their economically im-
portant but little known flora.
M . polygaloides Chodat was apparently never described; M. nitida
Chodat, Bull. Herb. Boiss. 3: 130. 1895, based on a specimen by
Pavon, possibly from Peru, cannot be placed from description and
is essentially a nomen nudum; M. rugosa Chodat I.e. 4: 251. 1896,
based upon a plant collected in Peru but without other data, is also
unrecognizable from the inadequate description.

related to Moutabea, thus removing it from the vicinity of Styrax.

characteristic for the Polygalaceae but otherwise they do not seem
to be particularly aberrant.

spikes solitary in the upper axils, finally 7 cm. long; sepals oblanceo-
late-oblong, about 6.5 mm. long, rounded at tip, puberulent-tomen-
tulose, nearly plane at anthesis; corolla tube 11-12 mm. long, rather
fleshy, lightly pilose, slightly ampliate above the somewhat spreading
obovate lobes 3.5-4 mm. long; stamens 8, 3 of them larger and
fertile, the remaining gradually smaller, the fleshy filaments 1 mm.

Guiana with 7 or 8 irregularly inserted stamens and unequally de-
veloped petals; the similar Lissocarpa Benth. of the Rio Negro has
8 stamens but they are inserted near the base of the corolla and
the filaments form an 8-dentate tube. These allied plants have also
been assigned to separate families, Diclidantheraceae and Lisso-

Slender trunked trees or shrubs (usually), sometimes clambering,
with alternate short-petioled entire leaves, small (rarely fimbriate)
deciduous stipules and rather inconspicuous flowers, often congested
in axillary panicles, or borne together on the petioles, or on the leaf
blades, polygamous or dioecious, rarely hermaphrodite, often a little
irregular. Sepals and petals 5(4), the former usually equal, sometimes
basally united, the latter free or more or less coherent and ordinarily
rounded or in varying degrees parted apically. Disk often with
glands or appendages at base of petals with which the stamens are
sometimes more or less joined, these usually 5(3), the anthers with
broadened connective. Ovary 2-3-celled, styles 2-3 rarely united
nearly to tip, the stigmas mostly capitulate; ovules 2, pendent.
Fruits often obliquely ovoid and rather flattened, commonly pubes-
cent and 1 -seeded. — Thought to be closely allied to Euphorbiaceae
with which Baillon united it. Some species, notably in Dichapetalum,
contain a very poisonous alkaloid.

calyx segments; fertile stamens unequal; anther connective sub-
glandular; staminodia two, entire or bifid; disk subentire or emargi-
nate; ovary 3-celled, the three styles pilose; fruit subglobose or
obliquely ovoid, lutescent ferrugineous, 1.5 cm. long, 1 cm. thick.—
Bentham separated his species on the basis of outer broader lanceo-
late corolla lobes, the flowers in size and shape resembling those of
T. ciliata Gardner, Hook. Icon. 5: pi. 466 (T. amazonica var. ciliata
[Gardner] Baill., 375), the younger, densely ciliate leaves with upper
midnerve tomentose, and somewhat pubescent beneath. Apparently
the Bentham plant was overlooked by Baillon in his account of the
Brazilian species in Martius' Flora.

Apparently a very distinct Tapura, the cream-colored flowers borne
well above the base of the phylloidiform leaves; the type was a 2-
meter tree.
In naming this for my well-known friend Julian Steyermark
meritorious recognition is given of his generous co-operation in the
preparation of this work, especially by his careful selection of her-
barium materials for my study.
Loreto: Florida near Rio Zubineta, King 2010, type. "Hibina."
Tapura leucantha K. Krause, Notizbl. Bot. Gart. Berlin 11:
136. 1931.
Glabrous except for the sparsely pilose branchlet tips, midrierve
of the thin herbaceous leaves beneath and the densely tomentose
sepals, these in life white or yellowish, unequal, oblong, obtuse, to
5 mm. long; petioles 3-5 mm. long; leaves narrowly oblong, sub-
abruptly cuspidate, with acumen 1.5-2 cm. long, base a little oblique,
10-13 cm. long, 3-4.5 cm. wide, with 7-9 slender lateral nerves;
flowers white, fragrant, few in axillary capitate cymes on the petioles,
the two subconcave larger petals to 8 mm. long; fertile stamens
two or three; style 1 cm. long, pilose to tip. — Like T. peruviana but
smaller in all parts except the yellow calyx and snow-white flowers
(Krause); and distinctions of doubtful value; the type from a 5-
meter tree densely branched at 2 meters, the trunk 1 dm. in diameter.
Flowers cream-colored, the fruit said to be yellow and edible (Mexia).

Branchlets as the 2-4 mm. long petioles sparsely pilose; leaves
thin, glabrous except for a few trichomes beneath, nearly oblong or
oblanceolate-oblong, longish cuspidate-acuminate, 10-13 cm. long,
3-4 cm. wide, the 5-6 lateral nerves little impressed above but
prominent beneath; flowers in axillary petiolar cymes (on the blade
above the petiole tip), yellow or orange in life; sepals ovate-oblong
or oblong, obtuse, tomentose, to 5 mm. long; larger concave petals
shortly bifid, 1.2 cm. long, smaller oblong; style glabrate above. —
Type from a tree 10 meters high. The extraordinarily large flowers
as well as the shape of the leaves make the species distinctive
(Krause). F.M. Neg. 13146.

4. GONYPETALUM Ule
Characters of the family in general. Flowers irregular, including
the basally united sepals, the two larger long-clawed petals attached
at base with fertile stamens, then twice geniculate and terminating
in a bilobed tip, the three smaller completely free, unparted but
also geniculate. Filaments of the three fertile stamens pubescent
at base; anthers cordate. Disk with two glands at base of sterile
filaments. Style filiform, shortly 3-parted.
Leaves minutely and sparsely pubescent beneath; flower clusters
sessile.
Leaves acutely acuminate, mostly about 8 cm. long, membranous.
G. acreanum.
Leaves obtuse or very shortly and obtusely acuminate, mostly
about 5 cm. long, coriaceous G. Tessmannii.
Leaves deciduously but densely pubescent beneath; flower clusters
somewhat peduncled G. juruanum.
Gonypetalum acreanum Ule, Notizbl. Bot. Gart. Berlin 6:
312. 1915.
Branches slender, terete; petioles 6-12 mm. long; leaves obovate-
oblong, slenderly long-acuminate, 7-10 cm. long, 2.5-3.5 cm. wide,
membranous, revolute-margined, glabrous above, sparsely pubescent
beneath, mostly on the slender nerves; flowers 20-30, subsessile in
crowded cymes, densely lanuginose; petals ochroleucous (or white),
the two larger nearly 5 mm. long, biparted into two obovate concave
lobes, the three smaller entire; stamens 5.5 mm. long, the three fertile
high connate with the larger petals, the two sterile little adnate with
the small petals; filaments as style and bases of petals very arachnoid-
lanate; disk lobes two, fleshy. — Author found variation in nature of
flowers suggesting Tapura. Type from trees 15-30 meters high in
terra firma. G. juruanum Ule is similar, but the larger (14-16 cm.)
leaves tapering more gradually to tip and densely pubescent beneath.
G. lanceolatum Ducke, Archiv. Jard. Bot. Rio Jan. 6: 43. 1933, of
the lower Amazon, is marked by glabrous lanceolate leaves 5-9 cm.
long, 2-3.5 cm. wide, stamens subequal, the long filaments strongly
white arachnoid. F.M. Neg. 45852.

Stout branchlets tomentulose; petioles 6-9 mm. long; leaves
oblong or obovate-oblong, 5-6.5 cm. long, 22-26 mm. wide, rather
broadly and obtusely acuminate, rigid-coriaceous, glabrous and
lustrous above, appressed pilose on midnerve beneath, otherwise
glabrous; lateral nerves 7-9, impressed above, prominent beneath;
flowers in capitate axillary cymes at tip of petiole; sepals unequal,
ovate-oblong, 2.5 mm. long, puberulent-tomentulose as the shorter
pedicels; petals yellow, unequal, larger 2.4-5 mm. long, long-clawed,
twice geniculate, biparted, the three smaller undivided; fertile
stamens three, 6 mm. long, anthers lanuginose; ovary tomentose. —
Differs from both described species by the broadened leaf-tip
(Krause), but is doubtfully more than a variant of G. acreanum.
The type from a 25-meter tree with trunk diameter of 1.3 meters,
densely branching at 15 meters. F.M. Neg. 13152.
