J. FRANCIS MACBRIDE
i. THE STATUS OF RYNCHOSPORA. SOME PERUVIAN
SEDGES
In considering the South American species of this well-known
group of Cyperaceae in connection with my own collections from
Peru, I was impressed with the similarity of certain members to
species of Dichromena Michx. Fl. Bor. Am. i : 37. 1803. On investiga-
tion I found that Rynchospora Vahl, Enum. 2: 229. 1806 (Rhyncho-
spora of authors) has frequently been amended to include Dichromena
and that authors who have maintained both genera have often done
so with evident misgivings. It seems sufficient to refer to Bentham
and Hooker, Gen. PI. 3: 1047. 1883 for a resume of the treatments
of authors to that date: Bockeler merged the two genera in 1872,
Linnaea 37: 525, and the recent distinguished student of the Cyper-
aceae, Kiikenthal, Bot. Jarhb. 56: Beiblatt 125: 16. 1921, followed
suit. C. B. Clarke, Urb. Symb. Ant. 2: 99. 1900, kept Dichromena
but remarked: "Genus a Rynchospora Sect. Psilocarya non nisi
differt spiculis capitatis, saepe stramineis vel cinnamomeis, nuces
paucas (1-3) maturantibus ; forsan cum cl. Boeckeler in Rynchospora
potius mergendum."
Yet this same authority retained in Rynchospora, cf. Kew Bull.
Misc. Inf. Add. Ser. 8: 117 et seq. 1908, species that exhibit in one or
more respects the salient characteristics upon which Dichromena has
been maintained as a genus, for instance, the characters of few nutlets,
or no setae, or simple capitate inflorescence, or preseence of foli-
aceous bracts. Among others mention may be made of R. Weber-
baueri Clarke, maturing 1-3 nutlets, of R. barbata (Vahl) Kunth and
R. rigida (Kunth) Bcklr. with involucrate capitate and pale inflo-
rescences but developed setae, of R. ebracteata (Standl.) Pfeiff. with
165

bracts reduced to subobscurity but in other respects with the char-
acters of Dichromena. The list could be extended of species such as
these that collectively at least show a dovetailing of all characters
upon which Dichromena has rested.
These "connecting" species are all tropical American : the botanist
writing on an area outside their range might well find it convenient
for himself and for his readers to recognize both genera, for there,
in aspect alone, they seem different enough. But from the stand-
point of sound taxonomy, all species considered, there is only one
generic concept, for which the proper name is Dichromena. Ryncho-
spora stands as a conserved name only for those who regard it as
distinct from Dichromena.
Probably the segregate genus Pleurostachya Brongn. should also
be included in Dichromena. It was regarded as a section only of
Rynchospora by Bentham and Hooker. There is an excellent review
of these and allied genera by Pfeiffer, Rep. Spec. Nov. 23: 342. 1927,
and his synopsis of the characters shows clearly their relative distinct-
ness, and the weakness of the particular segregates considered here.
The following species have been recorded as growing in Peru
with the exception of the first, which is cited as a representative
North Temperate species of the Section Rynchospora.

If I may judge from a specimen of Andre referred here, from near
Vista, Nov. Granat., this species differs from D. ciliata as indicated
by HBK. and appears to merit recognition, although reduced by
Clarke, Urb. Symb. Ant. 2: 101. 1900.

There seems to be good precedent for regarding this as a species.
Although it may be closely related to 5. tenuifolius, its suborbicular
scales are suggestive of those of 5. scaber. Originally Brazilian, it
is now known from the Departments of Ancash and Junin, Peru.

Yanamayo, below "Pillahuata," Dept. of Cuzco, May, 1925,
Francis W. Pennell 14073 (TYPE, Field Museum).
This species is entirely different from any so far recorded from
Peru and apparently has no known close relative. The collector
recorded the flower as "flesh ocher" in color. It is named for Dr
Herrera of the University of Cuzco, the distinguished authority on
the plants of the region.

NEW CAPERS FROM PERU 169
Probably this species most resembles C. longifolia Presl which,
however, is described as having lanceolate acuminate sepals and
much shorter (4 cm. long) pods. It is named for Reyes Figueroa of
Mito, Peru, in recognition of his loyalty and interest while serving
as guide on the Captain Marshall Field Botanical Expeditions of
1922 and 1923.
Cleome Herrerae, spec, nov., ut videtur peraffinis C. longifolia;
caulibus, foliis subtus, petiolisque plus minusve strigillosis ; sepalis

dense subadpresse strigillosis, 6-7 mm. longis; petalis oblongo-
lanceolatis, basi anguste attenuatis, circa 17 mm. longis; ovario
glabro; pedicellis fructiferis solum 1.5 cm. longis; siliquis (immaturis)
circa 5 cm. longis; stipes 3.5 cm. longis. PERU: Valle de San
Miguel, Cedrobamba, Dept. of Cuzco, 20 de Julio de 1928, F. L.
Herrera 1992 (TYPE, Field Museum).
C. longifolia Presl, Rel. Haenk. 2: 84. 1831, the only Peruvian
species to which this beautiful Cleome is closely related, is described
as having sepals that are attenuate at the base, petals about 12 mm.
long, pedicels 2.5 cm. long and pods about 4 cm. long. It does not
seem desirable at this time to regard these differences, definite as
they are, as representing merely a variation of this species. Dr.
Herrera reports the common name as "Facma."
Cleome limoneolens, spec, nov., C. chilensis peraffinis; basi
indurato-suffrutescens vel fruticosa, ramosa; caulibus aliquot dm.

3145 (TYPE, Field Museum); steep rocky grassland, Huacachi, near
Muna, Dept. of Huanuco, May 2o-June i, 1923, Macbride 4088.
This may prove to be only a variety of C. chilensis DC., which is
not uncommon in Peru, but no intermediate plants have been seen.
Its shrubby base and small flowers seem, therefore, to be distinctive
characters. The plants were noticeably lemon-scented.

No Peruvian species resembles this unusually well-marked
Cleome. Its strict habit, large greenish flowers with linear sepals
and petals, and long oblong-clavate pods are characteristics that
combined make it most distinctive. Yet I have not been able to
find a name for it and the material cited from Colombia and Mexico
was distributed unnamed.

12: 254. 1913, not C. microcarpa Ule, Bot. Jahrb. 42: 201. 1908.
Since there is already a Cleome Hassleriana this Paraguayan
species may be called eosina as it suggested to its author several
species, C. af finis DC., C. diffusa Banks and C. aculeata L.
Capparis Schunkei, spec, nov., arbor parva; ramulis glabris;

subabrupte breviter acuminatis basi subcuneatis, petiolatis (petiolis
circa 1.5 cm. longis), supra glabris (vel juventute minute stellato-

subferrugineo-stellato-pubescentibus; racemis ramosis aliquid pani-
culatis foliis brevioribus paucifloris; pedicellis gracilibus 1.5-2 cm.
longis; bracteis minutis caducissimis; calycibus petalisque mediocriter
externe fulvo-pubescentibus cum pilis stellatis; sepalis oblongo-
lanceolatis subacutis reflexis 3 mm. longis; squamulis circa i mm.
longis; petalis late ovatis subobtusis 5 mm. longis; staminibus circa
20 pistilloque longe exsertis; ovario ovoideo glabro. PERU: Chan-
chamayo Valley, Dept. of Junin, 1924-1927, Carlos Schunke 418
(TYPE, Field Museum); Hacienda Schunke, La Merced, Macbride
5701.
No species of the subgenus Colicodendron to which this plant
belongs appears to approach C. Schunkei except possibly C. lepi-
dota (Turcz.) Knuth of Venezuela from which it differs in character
of pubescence, shape of leaves and number of stamens. In foliage
only it suggests two glabrous Peruvian species, C. laurina HBK. and
C. Sprucei Eichl. both of which, however, belong in another subgenus.
PERUVIAN ANNONACEAE 171
C. Schunkei is a small tree with spreading branches and pale
greenish-yellow flowers. It is named with pleasure for the collector
whose hospitality I enjoyed when on the Captain Marshall Field
Botanical Expedition to Peru in 1923.
3. SOME PERUVIAN ANNONACEAE WITH
A NEW GUATTERIA
Guatteria Rusbyi, nom. nov. G. lucida Rusby, Mem. N. Y. Bot.
Gard. 7: 245. 1927, not G. lucida Presl, Rel. Haenk. 2: 78. 1831.
This recently described species from Bolivia may appropriately
bear the name of the author who evidently overlooked the much
earlier use of the term lucida for a distinct Peruvian species.
Guatteria pachypetala (Diels), comb. nov. Oxandra pachypetala
Diels, Notizb. 10: 173. 1927.
If one may judge from the original characterization, this Peruvian
tree is a Guatteria rather than an Oxandra because it has "stamina
numerosa" and "connectivum vix productum." According to all
authorities, even including Engler and Diels, Notizb. 3: 49. 1900,
Oxandra has few (6-18) stamens and the connective is produced
above the anther. If these characters do not "hold," Oxandra can
hardly be maintained as a distinct genus.
Guatteria socialis, spec, nov., liana; ramulis foliisque glabris;
foliorum petiolo prope i cm. longo supra nonnihil sulcato crasso,
lamina chartacea oblongo-vel ovato-elliptica plerumque circa 1 5 cm.
longa 4-7 cm. lata utrinque sensim angustata vel apice subabrupte
acuminata (acumine subobtusato) supra pallide-glauca nitidula
subtus viridi-nitidiore, nervis lateralibus primariis utrinque 9-11
angulo acuto adscendentibus subprominulis, venis reticulatis pro-
minulis; pedunculis glabris solitariis axillaribus subgracilibus 2.5-3
cm. longis, basi squamuloso-bracteolatis vix articulatis vel medio
quandoque unibracteolatis ; bracteolis minute ciliatis; sepalis orbi-
culari-ovatis subacutis solum minutissime ciliatis; petalis glabris
ut videtur subaequalibus subovatis vel oblongo-ellipticis circa 12
mm. longis, 6-8 mm. latis; baccis ignotis. PERU: Dept. Junin,
Chanchamayo Valley, 1500 m., Oct. 1924-27, Carlos Schunke jp5
(TYPE, Field Museum).
This was noted in the field by the observant collector to be a
liana and apparently is only the second scandent Guatteria to be
recorded. G. scandens Ducke has pubescent flowers. Dr. Diels has
described a climbing Annona (A. scandens Diels). In addition to the
habit this species seems to differ in size and shape of leaves, elongate
172 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. IV
peduncles, etc., from the comparatively few Guatterias with com-
pletely glabrous foliage and flowers. Its relationship may be with
G. jurensis Diels.
Fusaea rhombipetala (R. & P.), comb. nov. Anona rhombipetala
R. & P. ex G. Don, Gard. Diet, i: 87. 1831.
Safford has recently established the genus Fusaea, Contrib. U. S.
Nat. Herb. 18:64. 1914, and evidently for the most excellent reasons.
He has also indicated that the Peruvian species cited above is
in fact a Fusaea rather than an Annona but he did not make the
transfer.
Duguetia odorata (Diels), comb. nov. Aberemoa odorata Diels,
Notizb. 10: 171. 1927.
Duguetia pedunculata (Diels), comb. nov. Aberemoa pedunculata
Diels, Bot. Jahrb. 37: 409. 1906.
Duguetia peruviana (R. E. Fries), comb. nov. Aberemoa peru-
viana R. E. Fries, Kgl. Sv. Vet. Akad. Handl. 34, no. 5: 22, pi. 3,
fig. 1-3. 1900.
Duguetia St. Hil. Fl. Braz. Mer. i: 35. pi. 7. 1825 is "conserved"
according to the International Rules of Botanical Nomenclature in
place of Aberemoa Aubl. PI. Guian. 1:610. 1775. There seems always
to have been some question, however, as to the generic identity of
Aublet's plants with St. Hilaire's, and Safford has recently pointed
out (Contrib. U. S. Nat. Herb. 18: 60-6 1. 1914) that they can scarcely
be congeneric. The use of the name Aberemoa, therefore, should
remain restricted to the original and very imperfectly known species
A. guianensis Aubl.
4 . NEW AND RENAMED PERUVIAN MELASTOMES
Ernestia Sprucei (Cogn.), comb. nov. E. tenella (Bonpl.) DC.,
var. Sprucei Cogn. Bull. Acad. Belg. 3. 14: 929. 1887.
Cogniaux described this plant, to distinguish it from typical E.
tenella, as a branched shrub 1.5-2 m. high with purple flowers and
densely setose (at apex) ovary. These characters seem to me specific :
E. tenella is subherbaceous or woody below, 0.5 m. high and has
white flowers and a scarcely puberulent ovary.
Brachyotum callosum, spec, nov., fruticosum 0.5-1.5 m. altum,
dense ramosissimum ; ramis teretibus flexuosis adpresse setulosis
inferne demum glabratis; ramulis dense subadpresse setulosis
plerumque i dm. longis; foliis valde approximatis 3-nerviis oblongo-
PERUVIAN MELASTOMES 173
ellipticis utrinque obtusis 8-10 mm. longis, 4-5 mm. latis subplanis
vel mediocriter revolutis; petiolis (circa i mm. longis) foliisque
subtus adpresse densequ e setulosis, supra callis conicis apice breviter
setiferis dense onustis; floribus pedunculatis plerumque ternis 5-
meris (semper?) breviter pedicellatis ; bracteis tarde deciduis;
calycis tubo conico vel anguste campanulato parce adpresseque
strigoso circa 8 mm. longo, lobis triangulari-ovatis acutis circa
5 mm. longis; petalis late obovatis circa 12 mm. longis plus minusve
breviter ciliatis; antheris oblongo-linearibus, connective brevissime
elongate non tuberculato. PERU: in scattering hillside thickets,
15 miles northeast of Huanuco, June 12-22, 1922, Macbride &
Feather stone 2181 (TYPE, Field Museum).
This species is a member of the section Adesmiae and apparently
is most nearly related to B. Trianaei Cogn. Melast. 167. 1891, not-
withstanding it 5-merous flowers. It can be distinguished from
Cogniaux's plant by the entirely different pubescence of the leaves
and calyx. In some respects it resembles both B. lutescens (R. & P.)
Triana and B. microphyllum Triana but the pubescence of the former
is hispid and strigose and that of the latter sparsely strigose and
setulose. In most if not all species of Brachyotum the flowers may be
either 4- or 5-merous. For instance, B. lutescens was described as
sometimes 5-merous and so are my Peruvian specimens. B. callosum
therefore will probably be found to vary in the same way. Its flowers
(apparently yellowish) were not fully grown so the petals may become
longer than described.

Only two other species of the section Dicentrae seem to be closely
related to this, namely B. Maximowiczii Cogn. and B. rosmarinifolium
(R. & P.) Triana. B. Figueroae may be distinguished from the former
of these by its much shorter calyx-lobes in proportion to the tube
and whitish flowers, and from the latter by the broadly ovate leaves
that are hirsute rather than setulose beneath, as well as by the color

of the flowers and proportionately shorter calyx-lobes. It is named
for Reyes Figueroa, my helpful companion on many collecting
journeys in 1922 and 1923.

This species, definitely referable to the section Dicentrae, appa-
rently resembles both B. Grisebachii Cogn. and B. Naudinii Triana.
It differs from the former in its ovate rather than oblong leaves and
in its shorter and broader petals. The longer leaves and calyx-lobes
and rounded petals separate it from the latter. The pubescence
on the upper leaf-surfaces is peculiar in that each bristle emanates
from an elongate callous that scarcely exceeds the bristle in width
and is attached to or is a part of the leaf-surface.

I should be inclined to describe this variant as a new species
were it not for the apparent variability of T. longifolia and the fact
that the numerous segergates based on relative length of connective
and character and degree of pubescence when better known will
very likely be found to represent extremes only in different directions
of variation. The above variety resembles also T. stenopetala Cogn.
except that the petals are not narrowed at base.

This typical species of Monochaetum on casual observation would
readily pass for M. dicranantherum (R. & P.) Naud. but careful
examination discloses a number of differences that make its refer-
ence to the latter unsatisfactory. The calyx-hairs are nearly all
tipped with a gland; otherwise the pubescence is exactly that of M.
dicranantherum. Also the leaves are longer and more gradually
acute, and the appendage of the smaller anthers almost equals the
anther in length. These differences may be found to be relative but
at present there is no evidence to this effect.
M. subditivum bears some resemblance to M. mllosum Gleason,
Bull. Torr. Club, 52: 335, but the leaf-pubescence of the latter is
evenly distributed over the upper surfaces. In both M. dicranan-
therum and the species proposed here it is confined to lines between
the veins. There is also a difference in the relative size of the smaller
anthers and their appendages. Two other species that are related
are at once distinct because of their 7 -nerved leaves, namely M.
pauciflorum Triana and M. glanduliferum Triana.

This interesting new genus of the Melastomaceae was collected
on the second of the botanical expeditions to Peru sponsored by
Captain Marshall Field. It is an attractive plant with creeping
stem and somewhat fan-shaped leaves densely covered on the under
side with soft rusty-red hairs. The upper leaf -surface is dark green
and smooth. The flowers are a coral-pink with yellow anthers.
Marshallfieldia is not satisfactorily referable to any of the tribes
of its family as these have been characterized by Cogniaux in his
monograph, Melast. 1891. Although only flowering material is
known it appears to be allied to the Merianiae in which, however,
there are no genera with very unequal stamens. Notwithstanding
the unequal stamens its generic relationship is apparently with
Adelobotrys which it resembles in habit and foliage and exactly
matches in character of the anther-appendages but its calyx is
lobed like that of some species of Meriania.

This beautiful species, although clearly a member of the section

Only a few species of Tococa have sessile flowers borne in a
capitate inflorescence. Of these T. unddbunda most suggests T.
spadiciflora Triana, Trans. Linn. Soc. 28: 132. 1871 because of the
position of the vescicles on the petioles although that species has
5-plinerved leaves and bracteate flowers. If the occurrence of
vescicles is disregarded our plant appears to be more nearly related
to other species from all of which it is readily distinguished by
characters of pubescence, leaves, petioles and calyx. The calyx-
pubescence was pink. Sometimes but not usually the leaves beneath
the inflorescence are greatly reduced to nearly linear long-acuminate
bracts. The name refers to the flexuous branchlets, wavy leaf-
margins and cross-veins.

differs, especially in its acutish leaves, longer petioles, shorter ped-
icels and regularly lobed calyx. Its fleshy white flowers with con-
trasting blue anthers were very attractive. Its -name commemorates
fittingly the hospitality and aid in collecting extended by Mr.

This plant may be either a Topobea or a Blakea, so far as can be
determined from the fruiting material available. It seems unlikely,
however, that it is referable to the former genus since it most nearly
approaches in appearance two species of the latter, namely Blakea
caudata Triana and B. Holtonii Hochr. It differs from the former
in the narrower gradually acuminate leaves and the subsessile
flowers and from the latter in the 5 -nerved leaves and subsessile
flowers.

the number of flowers, B. incerta departs from the description of B,
Spruceana in a number of ways: the leaves, although indistinctly
are actually 7 -nerved, the petioles average longer, the pedicels are
shorter, the bracts are not at all acute and the calyx-lobes are longer.
It approaches B. latifolia (R. & P.) D. Don in some respects but is

It is unusual for a species of Miconia to have the anther-connec-
tive greatly prolonged but there is no doubt that such is the case
here: the filament itself is linear, not tapering, and shorter than the
connective. The relationship of M. Malatestae may be with M.
stipularis Naud. or M. scutata Gleason (of the section Amblyarrhena)
which it resembles vegetatively but its anthers are more nearly
characteristic of the section Eumiconia. The leaves, or the stamens
and ovary of the species mentioned are entirely different from those
of our plant.
M. Malatestae is named for Sr. Enrique Malatesta of Huanuco

This straggling shrub with pinkish-white flowers belongs in the
section Amblyarrhena and somewhat resembles several species but
PERUVIAN MELASTOMES 183
is entirely distinct by virtue of its triplinerved leaves the few other
species having this character being altogether different in other
respects. Sr. Francisco Pulgar of Panao, by his friendly interest
and influence assisted materially in the successful culmination of
the difficult trip to Muna and Pozuzo on which journey this fine
bush was collected.

other allies of M. capitellata Cogn. of the section Amblyarrhena,
from all of which it at least differs in the much longer calyx and
smaller leaves. Its pubescence seems to resemble that of M. radula

to M. peruviana Cogn. (Sect. Cramaniwri) but the latter has narrower
acute leaves and hirtellous rather than stellate pubescence.

In spite of the lack of flowers I have little hesitancy in proposing
this shrub as a new species because its general characteristics so
obviously ally it to M. flavescens Cogn. and other members of the
section Chaenopleura, to none of which, it can be referred. Its
sharply angled branches and the curious restriction of the pubescence
to the leaf -veins and the petioles are unusual characters for the group.
In naming this neat shrub for Mr. Ottiker, an official of the
Ferrocarril Central del Peru, I am recording with pleasure his very
welcome aid in the matter of transport from Lima to La Oroya.

Apparently this is a species of the section Cremanium and is
related in a general way to M. valida Cogn. and allies, in spite of
the rather narrow anthers. No species of Eumiconia seems, from
description, to resemble M. ramosipila at all closely.

It may seem unwise to describe as new a Miconia that is only
in bud so that the floral characters are not entirely discernible but
the anthers are sufficiently developed to enable one to place it in
either the section Cremanium or Chaenopleura. No described species
of either section, apparently, has such remarkably sulcate branches,
large glabrous leaves and extremely small flowers.

treated, it seems to me, as varieties of the species rather than as
varieties of two subspecies. This simpler classification is certainly

This species has the same curious appendages on the petioles
that are described as occuring on the probably closely related M.
nectaria. M. Aspiazui, however, is clearly distinct by virtue of its
very different foliage. It is named for Dr. R. Aspiazu, distinguished
physician and surgeon of Lima, and enthusiastic student of the
local flora who generously aided the work of the Captain Marshall
Field Botanical Expeditions to Peru.

The aspect of this shrub is that of several species in the section
Chaenopleura of Miconia but the broadly winged filaments and the
curious wing-like erect appendages at either side of the anther
at its base are characters that are entirely at variance with the
generic character of that genus. The fruit, however, is undoubt-
edly baccate which places the plant in the tribe Miconieae although
in this tribe highly specialized stamineal development is most
unusual. I am indebted to Dr. Paul C. Standley for suggesting the
generic name.

5. VARIANTS OF OSTRYA AND A TEXAS TEPHROSIA
OSTRYA VIRGINIANA (Mill.) K. Koch, forma glandulosa (Spach),
comb. nov. O. mrginica (Moench.) Willd., var. glandulosa Spach,
Ann. Sci. Nat. 2 se'r. 16: 246. 1841. 0. mrginiana (Mill.) K. Koch,
var. glandulosa (Spach) Sarg. Bot. Gaz. 62: 216. 1919.
My attention has been called to this form characterized by
the presence, in greater or less abundance, of stiffish glandular
trichomes intermixed with the usual substrigose pubescence of the
petioles, young branchlets and peduncles by my own collection,
number 7000 from Trout Park, Elgin, 111., Aug. 30, 1926. Examina-
tion of the series of specimens in the Illinois Herbarium of the
Field Museum indicates that this variant is not at all uncommon
and apparently grows together with the typical eglandular state of
the species, as observed for Indiana by Mr. Deam, Trees of Ind.,
Dept. Conserv. Publ. 13: 80. 1921. As there appear to be no other
differences associated with the glandulosity, it seems better to
regard it as merely a glandular form. House, N. Y. State Mus.
Bull. 254: 267. 1924 lists it for western New York with the remark
"is scarcely worthy of varietal rank." It seems to grow with the
typical form in general throughout the northern portion of the
species' range but the specimens of forma glandulosa that I have
seen from New England, New York and Pennsylvania are usually
less glandular than many, at least, of the collections from farther
west.
In this connection I have studied the specimens in the herbarium
of the Field Museum from the southern area of the species' range
and have reached the conclusion of Winkler, Pflanzenr. 4. 61: 22.
1 904, that the Mexican and Central American plants with somewhat
more pubescent more nearly oblong more or less doubly serrate
leaves are too nearly approached by material from the southern
states and accordingly are better regarded as constituting a geo-
graphical variety, that even then is often obscurely marked. Stand-
ley, Contrib. U. S. Nat. Herb. 23: 169. 1920, considers the Mexican
plant, under the name O. guatemalensis (Winkl.) Rose, "very closely
related to O. mrginiana but seems fairly distinct." However, he
describes the leaves as "ovate" which is indicative of their vari-
ability since the term is applicable particularly to the form proposed
as O. mexicana Rose, very properly referred by Standley to 0.
guatemalensis. If one regards 0. mrginiana as distinct from the Old
World 0. italica and the Mexican plant as a variety of the former,
its name and synonymy are as follows:

Dr. Rydberg's Cracca texana, I.e., is a fairly well marked herb-
arium species by virtue of the appressed strigose character of its
pubescence especially on the calyx and under surfaces of the leaves.
The pubescence of typical T. onobrychoides is more pilose in quality
and mostly spreading. However, there is some intermixture of
strigose hairs. Furthermore, as shown by the above citations, col-
lections have been made in the same localities that, except for this
somewhat variable difference in tjie nature of the pubescence,
appear to be indistinguishable. Accordingly it seems that the
character of T. onobrychoides can be most logically defined by
including C. texana in it as variety.
