Differs from glabrous or subglabrous forms of the similarly
amphicarpous Bidens Anthriscoides DC. in the dissection and outline
of the leaflets, in its proportionately much longer external involucral
bracts,1 and in its straighter achenes. The general aspect is some-
what like that in stunted, slender forms of B. pilosa var. bimucronata
f. odorata (Cav.) Sherff, but the very narrow external bracts and the
dimensions of the flowering and fruiting heads (the latter with
fewer achenes) distinguish it from that form.

Type specimen: Collected by Edouard Francois Andre, No. 2878,
at altitude of 1,250 meters, Rio Juanambu, Colombia, April 28,

Distribution: Known only from type locality, Rio Juanambu,
Colombia.
Specimens examined: Andre 2878 (type, Gray: cotype, Kew).
The type specimen was restudied in 1922 and again in 1925.
The 20-30 areolae on the old disks become prominent as the invo-
lucres reflex. There are 37 heads on the type. The plant appears to
be entirely herbaceous, but the label says "suffrutesc.," hence the
lower part of the plant (not present on the sheet) may have been
woody. The species stands very close to B. pilosa var. alausensis f .
scandicina (H.B.K.) Sherff, from which it appears to differ in its
taller stature, more acutely tetragonal stems, longer internodes,
finally much reflexed involucres, and, most of all, its very minute
flowering heads, these measuring only about 4 mm. high and equally
wide.1

Type specimen: Collected by Jean Luis Berlandier, No. 1010,
Cordillera de Guchilaque (near Cuernavaca, State of Morelos),
Mexico, October, 1827 (Del.).1
Distribution: Southwestern Mexico.

Guadalajara, Jalisco, October 17, 1903 (Field).
As stated before (Sherff, loc. cit.), examination of cotype material
in London (Brit.) and Paris (Par.) shows the species to have radiate
heads, not discoid as described by DeCandolle, exterior involucral
bracts much shorter than the interior, not subequal, and some of the
1 No. 1010 is the first cited specimen and hence may pass as the type. De
Candolle founded the species upon Berlandier 's Nos. 1010 and 1152, both from
the same locality. The specimens are identical.

(Berlandier 1010, Del.; Brit.; Par.) fairly well except in being gla-
brate. Elsewhere, the specimens of Pringle 11822 are seen to have
delicately bipinnate leaves, similar to those of B. pilosa var. bimu-
cronata f. odorata (Cav.) Sherff. Through this form, apparently best
regarded as a variety, B. Anthriscoides DC. is found to be rather
closely related to a form (the B. inermis Wats.) of B. pilosa var.
bimucronata f. odorata (Cav.) Sherff.1

OF 'THE
THE GENUS BIDENS 355
This species was stated definitely by DeCandolle (loc. cit.) to
come from Mexico, but Kunth (H.B.K. loc. cit.) was uncertain as to
its native country. It is known definitely only from Guatemala.
DeCandolle commented upon the closer affinity of the achenes with
those of Bidens than with those of Cosmos. Whether he altered the
specific name through intent or through error, I am unable to say.1
But later, Schultz Bipontinus (Seemann, loc. cit.), who frankly
declared his belief that Cosmos was not a valid genus, used this
altered name in citing it as a basis for his Bidens Kunthii, which
latter name, according to the International Rules, cannot stand.
Asa Gray (Proc. Amer. Acad. 19: 16. 1884) strongly suspected
that this plant was merely Bidens humilis H.B.K. and suggested a
reexamination of the type material. Kunth (H.B.K. loc. cit.) had
described the color of the ligules as "violacea, basim versus sulphurea."
This description is borne out, not only by the coloring in the plate
cited (that is, in copies of Kunth's work having the plates colored,
as in John Crerar Library, Chicago), but by the type specimen in
Paris, clearly the one from which the plate was made. This speci-
men, though faded as to its rays, shows at least that the proximal
ends of the rays were colored differently from the remaining portions,
which latter seem surely to have been some shade of red.
More recently, there has been collected in the Department of
Amatitlan, Guatemala, fine material, Heyde & Lux 6173, which
belongs here. Singularly enough, it had been determined by John
Donnell Smith as Bidens humilis (cf. Gray, loc. cit.), but the roseate
rays and more or less Cosmos-like aspect are very distinct. The color
of the rays in the dry condition varies from a pronounced roseate
to a faded yellowish color, rather than showing a distinct sulphureous
color definitely located toward the base as described by Kunth.
Still further material from the same small district in Guatemala,
W. A. Kellerman 6112, has been collected and fortunately is in a
more mature condition. The ripe achenes match the ovary figured
by Kunth and show that there is not the slightest tendency to
become rostrate as in most species of Cosmos.
An examination of the original description of Bidens parvulifolia
(Sherff, loc. cit.) shows that the second cited specimen, Heyde &
1 In his Prodromus Herbarium DeCandolle had mistaken a single large speci-
men of Bidens pilosa var. bimucronata f. odorata (Cav.) Sherff for this species. The
original label had said "Bidens Cavanilles" and from the peculiar fades of the
plant, the writing, etc., it is clearly one of the original specimens of Bidens odorata
Cav. that had been sent out by Cavanilles. On the cover, DeCandolle originally
had written "B. Chrysanthemoides? H.B.K." but later had changed the "B." to
"C."

Lux 6162, seen in the United States National Herbarium, was
obtained by the same collectors at the same altitude, locality, and
time as Heyde & Lux 6173. The dried ligules were yellowish,
the leaves were pubescent, and all but the top pair were simple.
Since then I have found other specimens (Heyde & Lux 6162) show-
ing numerous intergradations between the simple, pubescent leaves
and the compound, mainly glabrous leaves; also, variations to a
roseate color are shown in the rays. Thus Bidens parvulifolia,
incredible as it may seem to any botanist who does not have at hand
the intermediate specimens, must be interpreted as merely a form
of Bidens Chrysanthemifolia having minute, mainly undivided leaves.
B. Chrysanthemifolia offers a perplexing approach to B. pilosa
var. bimucronata f. odorata (Cav.) Sherff. It seems significant,
however, that among the large number of specimens of the rather
widely distributed f. odorata examined from elsewhere than in the
Department of Amatitlan, Guatemala, none have been found to
present the gradations from glabrous, decompound to pubescent,
undivided leaves that B. Chrysanthemifolia presents.

A species of highly restricted distribution. It appears most closely
related to Bidens pilosa var. calcicola, which at times offers a strong
resemblance. The clavate achenes of B. mollifolia, however, seem
very distinctive.

Type specimen: Collected by Abadia around Lima, Peru, in 1833
(Del.).
Distribution: Vicinity of Lima, Peru; also in Ecuador and
Colombia.
Specimens examined: Abadia, Lima, Peru, 1833 (type, Del.);
Bro. Ariste-Joseph A832, Choaclu, above Bogota, Colombia, July
(U.S. ; forma internodiis longissimis) ; Alexander Mathews 738, Lima

February, 1922 (U.S.) ; Luis Mille 486, in cultivated places, June,
1904 (U.S.; forma); ex herb. Pavonii, Lima and Chancay, Peru
(Boiss.; Flor.).
Bidens Abadiae DC. was founded upon a specimen collected at
Lima, Peru, in 1833. The leaves of the type are bipinnatisect, and
the general aspect of the foliage is comparable with that of B. pilosa
var. bimucronata f. odorata (Cav.) Sherff. In the Boissier Herbarium
is the plant from the Pa von Herbarium, and collected at Lima or in its
vicinity, a plant matching the type very closely in its bipinnatisect
foliage. The technical characters of both the old and young heads
on these plants are very similar to those often met with in B. pilosa
L. The general habit is so distinct, however, that to equate B.
Abadiae and B. pilosa would seem unjustifiable.

Type specimen: Collected by Hugh Cuming, No. 1041, Lima,
Peru, in 1831 (Kew, 2 sheets).
Distribution: Peru.
Specimens examined: Cuming 1041 (type, Kew, 2 sheets);
W. Nation, cultivated places, Lima, 1862 (Kew); ex herb. Pavonii
ex Peru (Webb) ; Dr. & Mrs. J. N. Rose 18740 p. p., Santa Clara,
July 18, 1914 (N.Y.).
In the Webb Herbarium at Florence is the additional specimen
(just cited) from the Pavon Herbarium, and collected in Peru. This
has the leaves merely tripartite, with the terminal lobe subtripartite.
The specimens by Cuming and by Nation, all from Lima, likewise
differ from the DeCandolle type of B. Abadiae in having leaves
only once-divided. One of the Cuming specimens has leaves ap-
proaching those of the related B. pilosa var. alausensis (H.B.K.)
Sherff. Since the difference between the simply pinnate and the bi-
pinnatisect types of foliage appears here to be emphatic, as in the
varieties of B. pilosa, I have given the name pilosoides to the variety
having 3-5-partite leaves.

The first type sheet bears two fine specimens, the larger one
having its leaves bipinnately divided. The specimens on the second
type sheet have the leaves mainly 3-5-partite, as in B. pilosa. The
achenes suggest those of B. pilosa var. bimucronata. The ray florets
suggest the ray florets of B. pilosa var. radiata. The combination
of achenial and radial characters with the strange general aspect
(especially in the case of the first specimen, with its bipinnate and
particularly white-hispid foliage) is one that I have never observed
in authentic material of B. pilosa. It seems best, therefore, to retain
B. Brandegeei as a separate species.

Type specimen: No type was cited. The habitat was given as
Virginia and the first pre-Linnean reference given for a synonym
(Chrysanthemum aquaticum, foliis multifidis cicutae nonnihil
similibus, virginianum. Herm. lugdb. 416. 1690) relates definitely
to a Virginia plant.1 The nativity of the specimen in the Linnean
Herbarium is not indicated on the sheet.
Distribution: Rhode Island to Florida and westward to Kansas
and Mexico; rare in California; scattered in French Guiana, Brazil,
Argentina, Chile, etc.; common in northern Italy and the Tyrol
and extending into France; also in British East India, China, Corea,
Japan, Kordofan, islands of Madagascar and Sokotra (east coast
of Africa), Lizard Island (northeast coast of Australia), Philippine
Islands, etc. Probably native in recent times only to the eastern
United States and eastern Asia, elsewhere introduced.2
Specimens examined: Ambrosius, in vineyards, Valsugana, Italy
(Del.); anon. (Linn., sub num. 6 et nom. bipinnata); anon. 63,
Lizard Isl., northeast coast of Australia, April, 1861 (Mus. V., 2
1 In early days the boundaries of Virginia extended much farther west, of
course, than at present. It may be added that in the later (posthumous) work of
Hermann's, his Paradisus Batavus (pi. 123. 1698), a crude illustration of an entire
plant was given, accompanied by the slightly modified name Chrysanthemum
Virginianum foliis Cicutae nonnihil Similibus. The plate was positively of our
Linnean B. bipinnata.
2 Other authors have commonly regarded this species as native to the United
States, whence introduced elsewhere. The characteristic and quite individual
aspect found in much of the Asiatic material, an aspect that has persisted through
specimens collected many years apart (and has occasioned the employment of
separate specific names), leaves no doubt, however, that eastern Asia has been a
home to this species since prehistoric times.

1913 (N.Y.).
Tausch (loc. cit.) had sought to distinguish among five forms
cultivated in gardens under the name B. bipinnata. He described
each form separately, retaining one as B. bipinnata and creating
new names for the other four. B. Cicutaefolia Tausch and B. Myrrhidi-
folia Tausch each is represented by one of his own cultivated
specimens (Lps.) and is seen to be purely B. bipinnata (vide sub B.
biternata). The meager description of B. tenuifolia Tausch matches
B. bipinnata as far as it goes. A plate cited by Tausch, "Chrysanthe-
mum cannabinum etc. Moris. Hist. 3™: tab. 7, fig. 23," is of B.
bipinnata and is so treated by DeCandolle (Prodr. 5: 603. 1836) and
0. E. Schulz (Bot. Jahrb. 50, Suppl. : 183. 1914). At Leipsic I failed
to find an authentic specimen of B. tenuifolia. B. elongata Tausch
appears likewise unrepresented by an authentic specimen to-day,
but the description given by Tausch, as also his context, leaves no
doubt as to the identity of B. elongata with B. bipinnata. The
various specimens examined of Kotschy 79, the basis of Bidens
Kotschyi, show mostly a variant of B. bipinnata in the direction of
B. biternata var. glabrata; indeed, that at Kew (not the type) is very
clearly B. biternata var. glabrata.
J. D. Hooker (loc. cit.) reduced B. bipinnata to varietal rank
under B. pilosa, a treatment not generally accepted by botanists since
then. True it is that Trimens (Fl. Ceyl. 3: 41. 1895) and also Th.
Cooke (Fl. Bombay Pres. 2: 44. 1904) regarded Hooker's "variety"
as "scarcely worth distinction" from B. pilosa. But this was before
the researches of 0. E. Schulz had placed B. pilosa, B. biternata,
and B. bipinnata upon a firm footing as to definite fruiting and
foliage characters.1
Of Bidens bipinnata var. minor Memm. I have seen no authentic
material. Memminger's description ("Very delicate, small, 10 cm.
high, in dense shade on rocks"), however, leaves little doubt that
1 Cooke expressly cited Trimens' conclusion, agreeing with it. Trimens, in
turn, doubtless was influenced by Hooker's grouping of B. bipinnata under B.
pilosa. In view of the superficially intermediate leaves of B. biternata (B. Wal-
lichii), a species very common in British East India, but erroneously equated by
Hooker with B. bipinnata, it was only natural that Trimens should have felt that
B. bipinnata equaled B. pilosa. Had he studied the fruiting characters as did
O. E. Schulz later, he would have concluded otherwise. Curiously enough, Hooker,
in publishing his work, relied here upon the erroneous treatment by C. B. Clarke
(Comp. Ind. 141), as stated elsewhere (vide sub B. biternata). Clarke, at a later
date, realized his own error and stated (on herb, label for H. Collett 816, Kew) that
"B. Wallichii DC. [i.e. B. biternata (Lour.) Merr. & Sherff] has the ray yellow (and
smaller) as well as different leaves and is a good species. C. B. Clarke. May 1894."

In its slightly dilated outer involucral bracts this variety makes
an approach toward Bidens pilosa L. The general aspect of the
plant is at once that of the South American B. subalternans DC. and
of the Old World B. biternata (Lour.) Merr. & Sherff, from both of
which it differs sharply in its achenes.

Type specimen: Collected by Menyhart, No. 1110, not abundant,
in shady places at St. Joseph, Boruma (Mburuma; Boroma; about
400-500 kilometers above Tete on Zambesi River), Northern Rho-
desia, April, 1892 (U.V.).
Distribution: From Boruma, Northern Rhodesia, southwestward
up the Zambesi River to the District of Sebungwe (Sebungu),
Southern Rhodesia; also north-northwestward to the Tschari
(Schari, Shari, Chari) River, Tschad (Tchad, Chad) Lake region,
some 3,000 kilometers distant.
Specimens examined: Aug. Chevalier 2816, along the Tschari
River, Tschad Lake region, Sudan, October 26, 1899 (Berl.); F.
Eyles (cult, e seminibus ab R. W. Jackio lectis, alt. 750 meters, Distr.
Sebungwe, Southern Rhodesia, November, 1920; Kew); ex Hort.
Vindobon. (cult, e seminibus Menyhartii numeri 1110; U.V., 2 sheets) ;
Menyhart 1110. (type, U.V.) ; Walter Robyns 2004, alt. 930 meters,
border of sandy beach of Lake Moero, Pweto, Belgian Congo, April
18, 1926 (Bruss.; nom. indig., Kasokopia).
The Chevalier specimen listed had been determined by 0. E.
Schulz as his Bidens Engleri, and in fact was cited by him, as was
also the nomen B. pilosa var. pauciflora, for that species at the
time of his original description (Bot. Jahrb. 50, Suppl.: 186. 1914).
Recently, I have been privileged to study not only Schulz's type of
B. Engleri (Berl.), but also excellent specimens of duplicate material
(Boiss.; Mus. V., etc.). These all agree in having plants of low
stature (2-3 dm. high), the leaves practically all undivided, the
heads discoid; the exterior involucral bracts only about 3 or 4,
spatulate, serrulate-ciliate, 1-2 mm. long; the inner bracts 2-5 times
as long, often rounded at apex; the'achenes all glabrous, parallel-
sided through most of their length and thus oW<mg(-linear, obcom-
pressed, about 1 mm. wide. With this material the Chevalier and
Menyhart specimens were compared and were seen to differ sharply
as follows: Height, 4-7 dm., leaves 3-5-parted, heads subradiate;
the exterior involucral bracts 6-8, linear and mostly narrowed above,
ciliate with slender hairs instead of with minute serrulations, 3-8

mm. long; the inner bracts mainly 1.1-2 times as long, subacute at
apex; the outer achenes frequently hairy, all narrower and gradually
attenuate upward, distinctly tetragonal, only 0.5-0.8 mm. wide.
A question at once arose from the fact that the Chevalier and
Menyhart specimens had come from localities 3,000 km. or more
apart, while the type material of B. Engleri had come from a point
more or less intermediate (about 6°-8° N. Lat. and 26°-28° E. Long.
In my judgment morphological considerations outweighed those
as to geographical distribution and appeared to compel a segregation
of the Chevalier and Menyhart (and, when later found, the Eyles
and Robyns) specimens as a species distinct from B. Engleri.
The name cylindrica alludes to the shape of the flowering heads
which, in the two specimens cultivated from achenes of Menyhart
1110, are notably cylindric.

In describing Bidens cognata, Greene (loc. cit.) stated that it was
"allied to B. heterosperma." He then proceeded to differentiate it
from that species, which was very easy because B. heterosperma was
so unlike it. Here, as in certain other cases (cf. Sherff, Bot. Gaz.

Type specimen: Collected by Ad. Stolz, No. 1442, in forest at
altitude of 900 meters, Kyimbila, Nyassaland, July 22, 1912 (Berl.,
2 sheets).
Distribution: Nyassaland to southeastern Belgian Congo.
Specimens examined: J. Bequaert 302, Elisabethville, Katanga,
Belgian Congo, April 4, 1912 (Bruss., 2 type sheets of B. ciliata
DeWild.); F. A. Rogers 10956, Elisabethville, Katanga, May, 1914
(Rog.); Stolz 1442 (type, Berl., 2 sheets: cotypes, Cop.; Del.; Mun.;
Mus. V.).
Unlike most other African species of Bidens, this possesses close
affinities with B. bipinnata L. and B. parviflora Willd. The type
specimens were small plants, but the cotypes and other specimens
later examined were much larger and better developed. From these
and also from the more robust material collected by Rogers in the
type locality, the original description has been amplified. B. ciliata

A species not easily confused with any other Asiatic species.
Known to Messerschmid as early as 1739 (or earlier),1 it was not
properly published until 1809. In that year Willdenow gave a technical
description of it, citing as an equivalent the name B. macrosperma
Fisch., which had been published without description in 1808. I
have seen very old-looking sheets of material (e.g., Mus. V.) with
merely the name macrosperma on the label and these match perfectly
the Willdenow specimens (Willd.) of B. parviflora. Poiret's private
specimen of B. pauciflora Poir. (Par.) likewise matches the Willdenow
specimens. Desfontaines' B. multifida was merely a nomen, listed
as being one used at the Paris Botanical Garden, and was equated
by Desfontaines himself with B. pauciflora Poir. Certain very old-
looking sheets of material labeled Bidens multifida Desf., still extant
in herbaria (e.g., Mus. V.) are, furthermore, merely B. parviflora
Willd. Turczaninow's original specimen of his B. Messerschmidii is
in the DeCandpllean Prodromus Herbarium (Del.) and likewise
is B. parviflora Willd.

0. E. Schulz, in his special study of Bidens chinensis Willd. and
related species (Bot. Jahrb. 50, Suppl. 178. 1914), appears to have
overlooked the Coreopsis biternata of Loureiro, published with a
description in 1790, some fourteen years earlier than the date of
Willdenow's work. In view of the many difficulties involved in
the interpretation of some of Loureiro's species, until recently I
myself have refrained from attempting final disposition of his names.
At last, however, these difficulties have been overcome and a cer-
tain and conclusive treatment becomes possible.
Loureiro described two species of Bidens, namely B. pilosa L.
and 5. bipinnata L., and two of Coreopsis, namely C. leucorrhiza Lour,
and C. biternata Lour. The first two may be passed over, since they
were admittedly not new species and since the known occurrence
of these two species in the region mentioned by Loureiro (Cochin-
China and China) tends to confirm the identity of the Loureiro
plants. The third species, Coreopsis leucorrhiza Lour., has recently
been referred (Bot. Gaz. 86: 443. 1928) to Bidens pilosa var. minor
(Bl.) Sherff.
The fourth species, C. biternata Lour., was known to Loureiro
under the Annamese dialectic name Ca ap chioc,1 and he stated that
1 Loureiro "lived at Hue for approximately thirty-five years, this town being
the ancient capital of the kingdom of Cochin China, now a part of French Indo-
China. I assume that the limits of the old kingdom of Cochin China were approxi-
mately the limits of the Province of Annam Anam, to-day, in French Indo-China.
On leaving Hue, Loureiro proceeded to Canton and spent two or three years there
before proceeding to Lisbon. . . . Loureiro tried to indicate in his native names as
between Annamese (indicated by the letter 'a') and Chinese names (really in
Mandarin) by the letter 'b'. . . by China he means the general vicinity of Canton
in Kwangtung Province. . . . Generally speaking: I am of the opinion that most
of his work was done on Cochin China specimens, chiefly for the reason that he
resided so long in Cochin China and for a comparatively brief time in Canton;
and the conditions in Canton at the time of his visit were such that it would have
been impossible for him to visit any regions outside of the immediate vicinity of
the city" Dr. Elmer D. Merrill in lit. April 22, 1929.

it grew in fields near Canton, China. His description follows:
"Differ, spec. Cor. foliis biternatis, ovato-lanceolatis, serratis: pani-
cula diffusa: radio sexfloro. Habitus et notae. Caulis herbaceus,
3-pedalis, erectus, 4-gonus, 4-sulcatus, integre luteus: panicula sparsa,
terminali. Radii corollae 6, neutrae. Pappus bicornis, ramosus.
Receptaculum planisculum, nudum."
His character for the foliage, biternatis, shows at once that he
was dealing with the same plant that Willdenow treated under the
name Bidens chinensis. His "pappus bicornis" was doubtless merely
one of the numerous errors for which his descriptions were noted.1
His "receptaculum .... nudum" probably was based upon capitula
that had shed their achenes and chaff scales, for just previously, in
his generic description of Coreopsis, he had said "recept. paleaceum."
In my monographic study of Bidens, I have found a considerable
number of specimens from the general region traversed by Loureiro
which are listed among the foregoing "Specimens examined."2
Recently I was supplied by Dr. Elmer D. Merrill with an excerpt
from the manuscript of his "A Commentary on Loureiro's Flora
Cochinchinensis" (since published; vide Trans. Amer. Phil. Soc. n.
ser. 24: 391. 1935). Merrill, too, had concluded Coreopsis biternata
Lour, to be the same as Bidens chinensis Willd. Since then, he has
assisted with various desired data and has recently joined me in
publishing the new combination which this conclusion made necessary.
In a former article (Bot. Gaz. 61: 499. 1916) I have remarked
upon the good historical summary for this species, with a compre-
hensive list of synonyms, presented by 0. E. Schulz (Bot. Jahrb. 50.
Suppl.: 176. 1914). It is seen that the history of B. biternata goes
back as far as Plukenet's Phytographia of 1691. Plukenet's plant
had been received from D. Petiver, to whom it had been brought
from China. The illustration later presented by Dillenius (Bidens
latifolia hirsutior, semine angustiore, radiato — Hort. Eltham. 51,
pi. 43. 1732) was deceivingly like B. biternata, although with leaves
somewhat narrower. The plant of the Dillenian Herbarium at Oxford
("no. 43.51.51") is found to be really Bidens pilosa L., however,
and so the Dillenian name must be excluded from synonymy.3
1 Occasionally the pappus is tricornis and it may very well be that he had so
spelled the word on sending it to the printer for the first edition. In any case this
error was not corrected in the second edition.
2 These mostly bear my herbarium determination, Bidens chinensis Willd. or,
incorrectly as to Linnaeus (see discussion in text), (L.) Willd.
3 In August, 1924, I examined Dillenius' plant at Oxford very carefully. The
two somewhat biternata-\ike leaves which, in the illustration, had caused 0. E.
Schulz, myself, and others to refer the Dillenian plate to B. biternata (or its syn-
398 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
The Rumphius plate, showing an entire fruiting plant from Amboina,
or a neighboring island, is very good and matches precisely, in its
individual aspect, many of the plants collected in that general region
in recent years. Varietally, however, it might profitably be regarded
as different from much of the B. biternata in other parts of the
Eastern Hemisphere, were there not here so many intergradations
as to make varietal distinctions in probably all cases, except for var.
glabrata, impossible. We may add that Rumphius' plate is partic-
ularly important because it is directly to that plate that Willde-
now's two synonyms lead (Willdenow did not cite B. pilosa var.
chinensis L. as a synonym!).
In several hundred herbarium determinations I have unfortu-
nately followed 0. E. Schulz in appending "(L.) Willd." to the name
there used (B. chinensis). As even Schulz admitted, the varietal
name as first published by Linnaeus in the Mantissa (p. 281. 1771)
was based upon cultivated material, which, from the Linnean descrip-
tion, was doubtless B. pilosa var. minor Sherff. The Linnean Her-
barium has several sheets pinned together in the Bidens pilosa cover.
One is labeled "Bidens 5 pilosa"; a second, "Bidens pilosa variety";
a third, "HU Radio albo" ; a fourth has on its back, "Rumph. amb. 6
t. 15." This fourth sheet has a plant with five heads, two of them
fruiting, and a separate leaf at one side. The leaf is 5-partite, with
the two basal leaflets each 2-partite because of an ovate leaflet on the
lower side. Examination of this material in 1914 and again in 1924
convinced me that this fourth sheet is of a merely freakish form of
B. pilosa var. minor, and not B. chinensis Willd. Hence Linnaeus'
name may well be left out of consideration here, and Willdenow, who
fortunately cited only the Systema Vegetabilium (ed. 13, p.) 610 1 for
his basis, may properly be given sole credit.
As stated previously (Bot. Gaz. loc. cit.), the figure in Plukenet's
Phytographia was cited by Tausch (Flora 19 : 395. 1836) for his Bidens
Cicutaefolia. A study of his context (some of which, unfortunately,
was not included in the manuscript copy before me at the previous
writing) shows that Tausch primarily was describing several species
of Bidens cultivated in gardens under the name of B. bipinnata and
that then, in the case of his B. Cicutaefolia, he added the Plukenet
reference. Under these circumstances, the Plukenet reference may
onym, B. chinensis), were detached from the main specimen and might have
belonged to another specimen. At any rate, the main specimen was very clearly
and positively Bidens pilosa L.
1 A work that omits Linnaeus' varietal name chinensis published three years
earlier and rests the variety directly upon Rumphius' Agrimonia molucca.

properly be discarded and Tausch's description itself,1 which con-
flicts with B. biternata as to achenes, be used instead. This course
led me some time ago to the conclusion that Tausch's B. Cicutaefolia
was probably a mere form of B. bipinnata L., a conclusion since
confirmed by examination of Tausch's own specimen (cult.) of
B. Cicutaefolia (Lps.).
The species B. biternata is usually distinguished easily from
typical B. pilosa by the leaves, the lower leaflets in the former
commonly being tripartite, not simple. The external involucral
bracts and the achenes also are usually distinct.
Gaudichaud's B. peduncularis, collected on Freycinet's voyage,
at the Island of Rawak of the Molucca Islands, is B. biternata. It is
of interest as having come from the same group of islands as Rum-
phius' Agrimonia molucca.* All through that region B. biternata is
common.
Miquel (Fl. Nederl. 2: 78. 1856) refers Agrimonia molucca Rumph.
to B. peduncularis Gaud, "(nisi ad praec. /3. [i.e., B. Wallichii var.
bimensis Miq.])." It is true that Miquel erroneously equated B.
sandvicensis Less, with B. peduncularis Gaud, but in this he doubt-
less was merely following DeCandolle's earlier treatment (Prodr. 5:
598. 1836). Interesting it is, then, to find that as early as 1856
Miquel had come almost to the point of synonymizing the two
names of Moluccan plants with each other and with B. Wallichii DC.
Of Bidens Wallichii DC. many authentic specimens are extant
today and they all are seen to be very definitely B. biternata. Thus,
for example, six uniform sheets of material occur in Berlin (Berl.).
These were collected by Wight, Prone, Tavoy, etc., and all are B.
biternata. They all are of the old Wallich distribution No. 3189,
cited by DeCandolle for his B. Wallichii. C. B. Clarke (Compos.
Ind. 141. 1876) reduced B. Wallichii to a variety of B. pilosa L.
but later, on a herbarium sheet in Kew Herbarium, admitted his
error in so doing.3
B. Wallichii var. bimensis Miq. was described from a specimen
collected by Rheinwardt on the Island of Bima, considerably to the
1 "Foliis bipinnatisectis glabris, laciniis ovatis dentatis, caule stricto, floribus
corymbosis subradiatis, involucre appresso, achaeniis erectis 2-aristatis."
2 For further data see under B. sandvicensis Less. (p. 123, footnote 1).
3 On the herbarium label for H. Collett 816, Clarke wrote, "I erred about these
two Indian Bidens ([sic] in my Comp. Indicae) and Sir J. D. Hfooker] unfortu-
nately 'followed' me.
"Bidens pilosa Linn, is B. leucantha Willd. and has the ray white. B. Wallichii
DC. has the ray yellow (and smaller) as well as different leaves and is a good species.

southwest of the Molucca Islands. From its description,1 it appears
to differ in no important respect from ordinary B. biternata.
B. chinensis f. simplicifolia 0. E. Schulz was based on Henry's
No. 388 from the Province of Hupeh, China. It is merely a small,
poorly developed form. The leaves are simple, as happens also in B.
pilosa, B. tripartita, and many other similar species when the growth
conditions are poor. One may well doubt the wisdom of assigning
indiscriminately to formal or varietal rank the many impoverished
or otherwise retarded forms of this nature that are found repeatedly
among herbarium specimens.2
Bidens pinnata Noronha (Verh. Batav. Gen. 5 [ed. 1.] Art. IV[?]
8. 1790) is listed without description but with the Java synonym
Harruga. It probably was either B. biternata or B. pilosa var.
minor, both of these plants being known in Java, probably without
distinction, under the name Harruga.

in uncultivated places at Hongno, September 23, 1908. There exist
fine specimens with these data in Geneva and Berlin (Taquet 969,
Del.; Berl.). They are B. biternata.
Plants by Bretschneider, David, etc., from the neighborhood of
Peking, China, display a remarkable approach or transition through
their more decompound and membranaceous leaves and their fre-
quently narrower and fewer-flowered heads to B. bipinnata L. (or
are even suggestive of the North American B. Bigelovii Gray and B.
leptocephala Sherff). A slightly similar approach is made rarely by
plants collected elsewhere (e.g., Macgillivray 63, Lizard Isl.).

In proposing as a new species his Bid-ens lasiocarpa, Schulz empha-
sized (in key, op. cit. 87) the fact that the outer achenes are more or
less recurved and commonly very densely hirtous, but this character
is present equally well in the type material of B. biternata var. glabrata
and its f. abyssinica, where it seems to have been overlooked by him.
Moreover, B. lasiocarpa has long achenes, as in the type material
of var. glabrata and, as a whole, is too closely connected by inter-
mediate forms in the herbaria to rank as a separate species. B. lasio-
carpa appears to bear somewhat the same relationship to the var.
glabrata as is borne by the peculiar local form found about Peking,
China, cited under the species proper, to the species itself. In both
cases there is a gradation of the foliage toward the more membrana-
ceous and more decompound type possessed by Bidens bipinnata L.

337 (type, Par.: cotypes, Berl., 2 sheets; Brit.; Del., 2 sheets; Kew,
3 sheets; Mo.; Mun.; Mus. V.; U.V.).
Some of Schimper's original specimens, on which were founded
the names Bidens abyssinica, B. abyssinica var. quadriaristata, and
B. quadriseta, are densely hairy forms with tripartite leaves and
conspicuously large fruiting heads. In leaf characters they might
be confused with B. pilosa L.; their achenes and involucral bracts,
however, are very distinct. Some cotypes of "B. abyssinica" (Brit.,
etc.) show leaves more incisely toothed or lobed and approaching
more or less closely those of B. biternata proper. The fruit characters
sometimes seem too distinctive to warrant reducing "B. abyssinica"
to subordinate rank under B. biternata as proposed by 0. E. Schulz,
but the great number of intergradations observed in various her-
barium specimens appears to compel some such course.
The varietal name incisifolia was given originally to specimens
of Schimper 2328, described (Oliver, loc. cit.) as having "rather
more deeply cut lobes." The authentic sheet of this number at Kew,
however, marked "Fl. Afr. Trop. iii p. 393," has none of its leaves
incisely toothed to a noticeable degree.

THE GENUS BIDENS 405
B. abyssinica var. quadriaristata Hochst. ex Schweinf. was
published without description, but based upon W. Schimper 729,
ad Gageros, September 16, 1854, etc. I have not seen this number,
but the data given by Schweinfurth are essentially the same as those
for Schimper 105 and 2324 already cited. Oliver and Hiern (in
Oliv. loc. cit.) cited this varietal name as a synonym for Bidens
quadriseta, but of course did not thus validate it as a varietal name,
nor did the varietal nomen incisi/olia receive valid publication.
Bidens laciniata Schz. Bip. ex Schweinf. was a nomen applied to
Kotschy 325. The material in Schultz Bipontinus' private herbarium
(Par.) had been received from the Vienna Botanical Garden. This
and also the more ample specimen in Vienna (Mus. V.) are the
f. abyssinica.

An African species comparable to Bidens tenera of northern
South America. The plants of the type collection all are less than
3 dm. high, and practically all the leaves are undivided. Hispid
outer achenes are lacking and the exterior involucral bracts are
mostly about 3 or 4 in number, 1-2 mm. long and spatulate, with
the margin, except near the base, minutely serrate. The achenes,
which tend to be rather parallel-sided throughout their length and
hence oblong-linear, are unique in appearance.
With B. Engleri Schulz identified an apparently different form,

Differs from the species proper in its more numerous achenes,
these quadriaristate and upwardly attenuated, not triaristate nor
almost parallel-sided throughout. The general aspect is that of a
thin-leaved form of Bidens pilosa L. as to foliage and of B. bipinnata
L. as to fruiting heads.
Bidens tenera var. tetracera, published in November, 1929,
was found to have been antedated several months by the equivalent
B. Ekmanii 0. E. Schulz and its so-called var. paucidentata, both of
Cuba. The type specimens of B. Ekmanii and its var. paucidentata
are now before me (through the kindness of Dr. Gunnar Samuelsson,
Director of the Botanical Section of the Natural History Royal
Museum of Stockholm). They differ mutually to an insignificant
extent, nor are they separable from the South American specimens
described for B. tenera var. tetracera.

Type specimen: Collected by Edward Palmer, No. 756, on west
side of Iron Mountain, vicinity of Durango, State of Durango,
Mexico, October, 1896 (Gray).
Distribution: States of Sonora and Chihuahua to State of
Mexico, Mexico.
Specimens examined: Berlandier 875, around City of Mexico,
Federal District, September 19, 1827 (Del.; Par.; type collection of
Bidens Anthriscoides var. angustiloba DC.); Edward Palmer 612,

At the time that this species was described, I looked upon B.
pilosa L., B. leucantha (L.) Willd., B. bimucronata Turcz., B. odorata
Cav., and several other similar forms as representing distinct species.
B. duranginensis, therefore, was considered to be a distinct form and
clearly entitled to specific rank. Since then, examination of a vast
410 FIELD MUSEUM OF NATURAL HISTORY— BOTANY, VOL. XVI
amount of additional material from European herbaria has com-
pelled the conclusion that these forms, while doubtless seeming
distinct in certain localities, at various places in their distributional
range intergrade so thoroughly that all hope of their specific segre-
gation must be abandoned.
This being true, the question at once arises whether B. duranginen-
sis, clearly a close relative of B. pilosa, is merely another of B. pilosa's
many varietal manifestations, or whether, like B. subalternans DC.,
B. biternata (Lour.) Merr. & Sherff, and several other pilosoid forms,
it is a valid species. Certainly it is very close in flowers and fruits
to some undisputed forms of B. pilosa var. radiata Schz. Bip. C. V.
Hartman 113 (alt. 1,740 meters, Las Calabazas, State of Sonora,
Mexico, October 9, 1890; Gray; Kew; Penn.; Phila.) is a form which
in some specimens appears closer to the young state of B. duranginen-
sis (as typified by Palmer 612) and yet in others appears referable to
B. pilosa var. radiata. Aside from questionable approaches of this
kind, I have been unable to obtain any legitimate basis for referring
B. duranginensis to synonymy and so feel compelled to retain it as a
separate species.

A species with somewhat the aspect of Cosmos. The flowering
heads are those of Bidens, however, and the achenes are not abruptly
narrowed above into a neck or beak as in typical Cosmos. The
general habit bears a superficial resemblance to that of certain
branched forms of the North American Bidens tenuisecta Gray.
Apparently the closest ally is B. andicola var. Cosmantha L Buch-
tienii. In fact, the fruiting characters of f . Buchtienii are so similar
that at first the remarkable habit and foliage differences in B. pseudo-
cosmos were thought attributable to the fact that the specimen came
from a larger plant than the observed specimens of f. Buchtienii.
Additional sheets of B. pseudocosmos were found later, however,
bearing small, entire, fruiting plants and even here both the habit
and the foliage distinctions were found to hold true.

of the Hortus Cliff ortianus (p. 399. 1737). The first and only
Hortus Cliffortianus synonym given was the Bidens latifolia hir-
sutior, semine angustiore radiato of Dillenius (Hort. Eltham. 51.
pi. 43. f. 51 and 1, 2, 3, 4- 1732). Dillenius' illustration was of a
specimen still extant in the Dillenian Herbarium (Oxf.; vide p. 397,
footnote 3), which is a slightly abnormal plant (as to leaves) of
the at present widely known and accepted Bidens pilosa L. An
excellent and more typical specimen is the one labeled Bidens pilosa
in the official Linnean set at London (Linn.).
Distribution: Widely distributed in tropical and subtropical
regions. In the Western Hemisphere from California southeastward
through Mexico, Central America, and South America to Chile,
Argentina, and Uruguay, also in the West Indies; throughout
Africa; in southeastern Asia, East Indies, Australia, New Zealand,
and many other islands of the Atlantic, Pacific, and Indian oceans.

1 In the fruiting stage, specimens of the minutely radiate var. minor fre-
quently look like those of the species proper and it is more than likely that several
collections have been included here for B. pilosa whereas younger material (i.e., in
its minutely radiate state) would have led to determination as var. minor. In a
number of cases, I had determined specimens in certain herbaria as B. pilosa and
later found the duplicates in other herbaria to be characteristic of the var. minor.
In all such cases, as far as known, the collections are cited under that variety.

The pre-Linnean setting of B. pilosa has already been given (vide
sub "Type specimen"). Much pertinent material will be found
under the following varieties and formae. We may note the status
of certain post-Linnean synonyms which either are not self-explana-
tory or else do not receive adequate treatment in the list of "Speci-
mens examined."
The name Bidens reflexa Link has been variously construed by
botanists during the past century. This is doubtless due to the fact
that more than one species was obtained in European botanical
gardens from supposedly B. reflexa achenes which had been sent
out from Berlin. Thus, some of the B. reflexa material in the Berlin
Herbarium is 5. pilosa L., while in the Herbarium of the University
of Halle, for example, a specimen labeled "Bidens reflexa Hort. bot.
Berol." is really B. serrulata (Poir.) Desf. Fortunately there exists
in the Berlin Herbarium an original specimen by Link. Its main
label says, in pencil, "Bidens sp. Mexico." In ink is written "reflexa
m. (Link)." Another label says, "Bidens reflexa Link En. 2. p. 306.
Hort. Bot. Berol." This specimen is clearly of Link's type material
and matches his description, except that he erred in calling it a
perennial, for it is an annual. It is nothing more than B. pilosa L.,
to which it must be referred.
A careful study of Vellozo's description and illustration of his
B. adhaerescens shows that plant to be none other than B. pilosa L.
His description of the capitulum is not above criticism. In the short,
abridged description at the beginning we read: "floribus terminalibus,
discoideis," which would limit the description to B. pilosa proper.
In the detailed description which follows, however, we read: "Co-
1 In South America B. pilosa, in common with such related species as B.
Gardneri and B. riparia, is often called Picao (fide F. Hoehnei et al.).
Concerning the value of B. pilosa as a forage plant, especially for horses with
intestinal parasites, and as a plant to be considered in connection with bananas
for cultivation, vide DeWildeman, PI. Util. Inter. 556-557. 1903.

rollula composite, quandoque radiata, radis octo ligulatis, albis."
Thus it is seen that he really included also the plants with white
rays, forms which today are separately treated as B. pilosa var.
radiata Schz. Bip.1
An original specimen of B. ciliata Hoffmgg. is in the collection
of the younger Reichenbach at the Museum of Vienna. It was
collected by Dr. Hoffmannsegg. It is a nearly glabrous plant, with
discoid heads, and is typical B. pilosa L. In the original description
it was differentiated from B. pilosa because of its polymorphous
leaves, a character of no value here, since B. pilosa L., B. subalternans
DC., and most other species of Bidens display a noticeable,some-
times very high degree of foliar polymorphism.
A sheet bearing two type specimens of B. Montaubanii Phil, is
in Berlin (Berl.). These were received from Philippi. They display, in
the narrowness of their leaflets, a superficial resemblance to certain
specimens of the South American B. subalternans DC., but differ
in having leaves pinnate, not bipinnate, and the achenes 2-aristate,
not 2-4-aristate. A study of their foliage, achenes, and involucres
shows that they are mere foliage forms of B. pilosa L.

Bidens pilosa L. has among its various varieties and formae a
subradiate variety, widely distributed in both hemispheres. This
was observed by Cassini.1 0. E. Schulz (loc. cit.) has employed for
it the varietal name dubia, but the synonymous Bidens sundaica Bl.
had already been reduced to varietal rank by Hasskarl (loc. cit.) in
1844, and so takes precedence over the name dubia. In his original
description Blume (loc. cit.) listed a variety minor, "caule foliisque
humilioribus. Crescit: cum praecedente [i.e., B. sundaica ips.,
prope Buitenzorg, Java]." Recently, through the kindness of Dr.
J. W. C. Goethart, Director of the Royal Herbarium at Leyden, I
was privileged to examine early specimens by Blume and by Jung-
huhn, from Java. Three sheets (Nos. 900,146 ... 72 pro parte;
900,146 ... 73; 900,146 ... 75) bear excellent specimens of Blume's
Bidens sundaica. A few minute rays are present. The first of these
sheets bears also the basal part of a specimen (and a fruiting
branch which probably belonged to it), labeled unmistakably in
Blume's own handwriting, "Bidens Sundaica Variet." Dr. Goethart
(in lit.) very properly regards this as "probably type of var. minor."
The one fruiting head still attached to the rather depauperate basal
portion exactly matches the others on the B. sundaica plants. A
fourth sheet bears still more depauperate material collected by Dr.
Fr. Junghuhn, No. 357, on Mt. Dieng, Java. It is labeled in Miquel's2
handwriting (fide Goethartii in lit.) as a depauperate forma of B.
sundaica Bl. Indeed, its three specimens (one of them, in flower,
1 "... les calathides, composees d'un disque jaune et d'une couronne blan-
chatre, sont larges de cinq lignes. . . . Nous ayons observe, pendant plusiers
annees, des individus vivans de cette espece, cultives au Jardin du Roi, et nous
avons remarque que leurs calathides etoient le plus souvent incouronees, rarement
radiees. Dans ce dernier cas, la couronne etoit composee de cinq a sept fleurs, dont
la corolle avoit le tube court, et la languette courte, large, orbiculaire, tridentee
au sommet, multinervee, a nervures jaunatres. . . . "- — Cassini, loc. cit.
2 Miquel (loc. cit.) cites a depauperate form collected by Junghuhn: "B.
leucantha /3. sundaica Hassk. I.e. p. 100, cujus auctoritate formam hanc alioquin
satis constantem hue retuli. — Formam omnibus partibus depauperatam in elevati-
oribus montanis Javae insulae el. Jungh. legit."
428 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
having the tiny rays very evident) are so obviously a merely less
developed form of B. sundaica, that few if any authors today would
seek to draw any distinctions.
It is evident that the actually equivalent name minor, given
varietal status long before the name sundaica was, must in turn take
precedence, supplanting both sundaica and dubia.1
Blume's description, "B. floribus subradiatis ..." is matched
by upwards of a thousand specimens examined in the past few years.
It is represented in particular by several of Blume's own specimens
(Brit., sub numero 139; Del.; Par.; Webb). In the Delessert, Paris,
and Webb herbaria the heads are mostly rayless, perhaps having had
the few rays removed in previous examinations. The foliage aspect,
however, is definitely that of the ordinary subradiate variety. Fur-
thermore, the plant at the British Museum of Natural History is
definitely subradiate.2
Even earlier than Blume's var. minor is Bidens pilosa var. chi-
nensis L. Mantiss. PI. 281. 1771, a name omitted from the foregoing
list of synonyms.3 Linnaeus' original description follows: "Habitat
in India orientali. H.U. Planta simillima Bid. pilosae, si non
eadem, sed radio diversa. Folia supra nuda, sicca ut fere scariosa.
Flosculi marginales nivei (nee albi) tamen hermaphroditi fertiles;
primo anno sati erant conformes flosculis disci, nee majores, altero
anno erant radio explanato quinquefioro piano parvo. Semina radii
aristis 4. s. 5, quae in B. pilosa vulgari radiis 2. s. 3."
It is seen that the Linnean plants, in the first year of their sowing
(they were annuals of course), had no ray flowers and thus were
typical B. pilosa. In a subsequent year, five small rays appeared.
It would seem that if Linnaeus' observations were flawless, and not
founded upon confused forms, the reason for distinguishing our
minor varietally (i.e., its constancy) would automatically disappear.
If we consider, however, the color of the rays in the later plants, it
is seen that some were glistening- or snowy-white while some were
1 Cf. O. E. Schulz (Bot. Jahrb. 50, Suppl. 179. 1914), ". . . dagegen gehoren
B. sundaicus . . . und var. minor . . . wahrscheinlich zu B. pilosus L. var. dubius
(Cass.) 0. E. S." In herbarium determinations, I have not differentiated between
forms having or lacking aristae on the ovaries of the ligulate florets.
2 In my cultural observations the var. minor appeared to come very true to a
given type. For example, in some two dozen plants (Sherff 2043) raised in 1915
from achenes on specimens sent by Mr. St. Ahnne (Bot. Gard. Raoul, Papeete,
Tahiti), the hundreds of flowering heads had uniformly tiny, distinctly yellowish,
ligulate florets, as had been observed on the parent material.

other shades.1 My field and herbarium observations indicate a
pronounced constancy in the ray color for any one collection of
plants of var. minor. Therefore, it appears probable that some
of the smaller-rayed forms of B. pilosa var. radiata composed at
least a part of the later material examined by Linnaeus. His her-
barium affords no help in solving the matter.2 Surely, there is so
much of uncertainty in the application of the Linnean concept that
it appears unwise to adopt it as against the clear and certain con-
cept associated with the varietal name minor.3
Bidens aurantiaca Colenso has its description ("Florets . . .
small, bright dark orange: ray-few, . . . ") supplemented by the
authentic Colenso specimen at Kew. This has the one flowering
head now lacking rays, but the aspect of the various critical struc-
tures is more properly that of the variety minor than of B.
pilosa proper.
Klatt's type of B. africana, as already pointed out (Bot. Gaz.
85: 14. 1928), was a plant collected by Dr. C. Keller, on Reunion
Island, summer of 1886. The herbarium containing the type was
not cited nor have I succeeded in locating an authentic specimen.
At Gray Herbarium are various tracings by Klatt, which form an
important part of the Klatt Herbarium obtained by that institution
some years ago. One of these is of B. africana. The plant represented
is seen to be widely remote from B. Lantanoides Gray and B. hawai-
ensis Gray, with which Klatt compared it in his original description.
The tracing, construed with Klatt's description (" . . . Die eiformi-
gen Strahlbliiten sind 2-3 mm. lang . . . "), shows that the plant
was, beyond all reasonable doubt, merely a simple-leaved form of B.
pilosa var. minor.

ently the only permissible way: "snowy-white (also, not white)."
2 There are four sheets pinned together; one, correctly labeled Bidens pilosa;
a second, labeled "B. pilosa variety" and determined by me as B. pilosa; a third,
from the Hortus Upsalensis, with merely the inscription "Radio albo," and
belonging to B. pilosa var. minor; a fourth, with the inscription (on back of sheet,
"Rumph. amb. 6, t. 15") and identified by me as B. pilosa.
3 It may be noted that O. E. Schulz has likewise declined, in his writings upon
Bidens, to adopt the name chinensis for this variety.

Linnaeus, in giving the habitat of his Coreopsis leucanthema,
said, "Hab. in Amer. Miller." In the Coreopsis cover in the Linnean
Herbarium is still to be found Linnaeus' specimen. It is somewhat
immature but has one head with whitish rays. These are less well
developed than those usually found, but much more conspicuous
than those on the radiate or subradiate var. minor. The sheet is
labeled "Leucanthema radio albo." The spelling "leucanthema"
is seen to agree with that found originally in the Amoenitates Acade-
micae and not that later published (leucantha) in the second edition
of the Species Plantarum. Linnaeus cited two synonyms, the first
(Bidens americana trifolia, leucanthemi flore. Tournefort. inst.
462) being apparently that from which he derived the name leucan-
thema. In his Systema Naturae ed. 10. 2: 1228, published in 1759,
he again used the name leucanthema. Although the name leucantha
was adopted later by Willdenow (loc. cit.) and has been accepted
widely since then, the original spelling leucanthema was restored by
Krause (loc. cit.).
When we trace the above Linnean citation of Tournefort's
Institutiones, we find that Tournefort gave merely two lines for
the plant later cited by Linnaeus: "Bidens trifolia, Americana,
Leucanthemi flore. Chrysanthemum Americanum, Ciceris folio
glabro, Bellidis majoris flore Prodr. Par. Bat." Thus it is seen that
Linnaeus' first cited synonym goes back directly to the plant listed
in Hermann's Paradisi Batavi Prodromus. However, this cited plant
is the same as that listed in the somewhat later (posthumous)
Paradisus Batavus (edited by William Sherard), which was cited by
Linnaeus for his Coreopsis alba.1
1 Linnaeus' description of C. alba, the second citation, and the habitat all refer
to Herm. Par. Bat. 124, pi. 1%^, His first citation, however, is to an entirely
different plant (Coreopsis scandens, foliis serratis ternato-pinnatis, receptaculo
438 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
On studying the original Coreopsis leucanthema description and
habitat data ("Caulis trium vel quatuor pedum, .... Foliolis
quinque, rarius tribus, ovatis .... Habitat in America. Miller
..." Amoen. Acad. 4: 291. 1759), we see that Linnaeus did not
really have in mind the plant of Hermann's, but rather a plant re-
ceived from Philip Miller and perhaps the same specimen that is
left to-day in the Linnean Herbarium.1 Later, Linnaeus very clearly
showed his belief that the two plants were different specifically,
naming the Hermann plant Coreopsis alba. DeCandolle (loc. cit.)
accepted this treatment, transferring Coreopsis alba to Bidens to
accord with the position of Bidens leucantha (L.) Willd. A few
years ago I dealt with these last two names (Bot. Gaz. 64: 32. 1917),
stating that it "seems much the safer course to retain the two
names separately for the present rather than merge them as done by
O. E. Schulz." Since that time I have examined several hundreds of
additional specimens and recently have concluded that B. leucantha
and B. alba are related to each other as variety and forma (becoming
respectively, as will be seen in the following text, var. radiata and
var. radiata f. Dondiaefolia) .2
Willdenow compared his B. leucantha with B. biternata (Lour.)
Merr. & Sherff, B. pilosa L., and B. pilosa var. minor (Bl.) Sherff for
several years under cultivation and decided it to be distinct: "Jam
per plures annos cum binis sequentibus3 culta faciem servavit"
(Sp. PI. 3: 1719. 1804). Since Willdenow's time its status has been
the subject of. much difference of opinion. Asa Gray, who gave
considerable attention to this matter, wrote (Proc. Amer. Acad.
nudo. Brown, jam. 321) and must be excluded, as it conflicts with the Linnean
description (cf. DC. Prodr. 5: 605. 1836. — "Syn. Brownei a Linnaeo citatum
videtur alienum ex recept. nudo dicto"). The Browne plant, if a Bidens, was one
of the tall, yellow-flowered climbers found in Jamaica, not the lower, white-
flowered species that Linnaeus had in mind.
1 The fact that the sheet bears, as already stated, the original spelling "leucan-
tiiema" rather than the later spelling "leucantha" may be taken as evidence that
the plant is the original Miller specimen.
2 In a former article (Bot. Gaz. 64: 32. 1917), I stated the reasons for believing
that Bidens Dondiaefolia Less, was synonymous with Coreopsis alba L. Subse-
quently I have found Lessing's type (Hlle.). It matches exactly (cf. Sherff,
Bot. Gaz. 81: 44. 1926) the Milller specimen (No. 148; N.Y.) formerly cited by me,
thus confirming the earlier treatment. For detailed presentation, see under var. 7.
radiata f. 2. Dondiaefolia.
3 Viz., B. biternata (B. chinensis) and B. pilosa. But Willdenow's herbarium
material of B. biternata (Willd. No. 15023) consists of 4 sheets, nos. 1, 2, 3, and 4.
Nos. 1-3 are B. pilosa L. var. minor and only No. 4 bears true B. biternata (cf.
O. E. Schulz, in Urb. Symb. Antill. 7: 135. 1911; cf. G. Walpers— Nov. Act. Nat.
Cur. 19, Suppl. 1: 271. 1843 — who erroneously interpreted Willdenow's herb. No.
15023 as being identical with his — i.e., Willdenow's — herb. No. 15022, B. pilosa
var. radiata, i.e., B. leucantha Willd.).

19: 16. 1884): "B. leucantha Willd. This, the Coreopsis leucanthema
L. Amoen. Acad., C. leucantha L. Sp. ed. 2,-1282 (Desc. Fl. Ant.
t. 583), and the C. coronata L. as to Plumier's plant, I take to be
quite distinct from the radiate form of B. pilosa." But 0. E. Schulz,
whose writings display a profound and comprehensive knowledge of
a number of the species of Bidens, treats B. alba, by which he means
B. leucantha Willd., as merely a variety of B. pilosa ("Einige Autoren
wollen auch jetzt noch die Abart als selbstandige Art betrachten.
Dieser Ansicht kann ich aber nicht beipflichten, weil ich oft direkte
Ubergangsformen gesehen habe." — Bot. Jahrb. 50, Suppl. 176. 1914).
In 1913, Dr. N. L. Britton, who had had considerable field
experience with these forms, told me that B. leucantha and B. pilosa
seemed to him unquestionably distinct species, not only in leaf and
ray but in the appression of the involucral bracts at anthesis. In
1916, however, he stated to me that as a result of further field
observations he had decided to equate the two in one species. Not-
withstanding the opinion held by Schulz, Britton, and many others,
I have until recently maintained the two as separate species. A
study of the large assemblage of specimens in Berlin has revealed,
however, several "direkte Ubergangsformen" that efface quite
effectually the specific limits and compel the adoption of a varietal
rank for the radiate form. Schultz Bipontinus' name B. pilosa var.
radiata is apparently the earliest pertaining to varietal rank.
B. striata Sweet (loc. cit.; etiam Curtis' Bot. Mag. 59: pi. 3155.
1832) is a form with large, particularly roseate rays.1
The pre-Linnean Bidens trifolia Feuill. (not listed above) is cited
by some authors (e.g., Gay, Hist. Chil. 4: 293. 1849; Reiche, Fl.
Chil. 4: 103. 1905) as a synonym for B. pilosa var alausensis (H.B.K.)
Sherff. The leaves in Feuilles' illustration (Journ. Observ. 3: 10,
pi. 4. 1725), however, match better those of B. pilosa var. radiata.-
Under the name B. leucantha the Materia Medica Mexicana (2:
153-172. 1898) gives a comprehensive treatment from the standpoints
of history, medicine, botany, etc. The treatment there doubtless
applies to the vars. radiata and bimucronata, each in part.

In his Flora of The British West Indian Islands (p. 373. 1861),
Grisebach stated that "a remarkable form, with all the leaves simple,
hispidulous achenia, and whitish-pubescent involucres, was collected
by Dr. Alexander, but transitions into the common B. leucanthus
[i.e., B. pilosa var. radiata Schz. Bip.] occur among Mr. March's
specimens." A former study of Alexander's materials left me
unconvinced as to the value of their simple-leaved character for
drawing taxonomic distinctions. The recently collected specimens
by De La Cruz were obtained at different localities and about two
months apart, yet both reveal in all respects a striking similarity.
The leaves all are simple, thin, glabrous, the blades ovate-lanceolate,
serrate, acute or subacuminate at apex, the larger ones about 3.5-4
cm. long and 1.5-2 cm. wide, the petioles slender and 1-2 cm. long.
Compared with chance, more or less simple-leaved plants of B.
pilosa proper that are sometimes found (B. pilosa discodea Schz. Bip.
em. 1. subsimplicifolia 0. Ktze. Rev. Gen. 1: 322. 1891; "folia omnia
vel plurima integra (cfr. Gris. Fl. Westindien)" — Ktze. loc. cit.),
also of B. pilosa var. radiata proper (B. pilosa var. leucantha f. sub-
simplicifolia 0. Ktze. Rev. Gen. 1: 322. 1891), these plants appear to
represent a more pronounced and less ephemeral form.

For many years, Persoon's variety odoratissima of Coreopsis
Ferulae/olio, seems to have been unfamiliar to botanists. DeCandolle
(loc. cit.) merely mentioned it: "quid sit var. odoratissima a Per-
soonio citata ignore." Persoon's variety was founded on Cavanilles'
plant in Jussieu's herbarium and was said to be native to Peru. This
cited specimen I have not found, but there exists in the British
Museum of Natural History a good specimen from Cavanilles,
labeled "Coreopsis odoratissima nobis, Mexico," which matches
Persoon's description precisely. The leaves, probably because of
having grown under cultivation, are especially slender-divided and
give a superficial resemblance to those of Bidens Ferulaefolia (Jacq.)
DC. The specimen is identical with two other specimens (Brit.)
from the herbarium of Cavanilles, one labeled "Coreopsis odorata
olim Bidens," and the other "Bidens odorata Cav. Ic. V. 1., nunc
Coreopsis." Both of these last two are further labeled, in pencil,
"Cosmos odoratus" Clearly, Persoon's variety is perfectly synony-
mous with Bidens odorata Cav.
Coreopsis multifida DC. and its var. mutica DC. are represented
by the type specimens in the herbarium of DeCandolle's Prodromus
(Del.). The species was collected (fide DC. loc. cit.), by Pa von,
possibly in Peru; the variety was from seed previously sent by Dom-
bey from "Peruvia" to the Botanical Garden at Paris. Both are
found on careful comparisons to be merely Bidens odorata Cav.1
1 The citation of Peru would seem to indicate that the material is really best
considered as the rather similar var. alausensis f. Scandicina, the form native to
South America. The plants are more like the North American material of f.
odorata. Whether a mistake was made originally in the mention of Pavon and
Peru for these plants I can not say for certainty, although the indications point
that way. We may note the partly comparable case of Bidens Sambucifolia Cav.,
said to have come from Peru and Mexico, but which has never been known from
outside of Mexico. The evidence in herbaria indicates that Cavanilles got his
material in this case from or rather through Pavon, and thus Pavon's written data
were at fault. Regarding another, somewhat different case of mislabeling observed
in much of the "Pavon" material cf. Hemsley, Biol. Centr. Amer. Bot. 4: 120.
1887 ("as Pavon himself was never in Mexico, and there is evidence of his having
dealt freely in the sale of dried plants").
448 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
Bidens Caucalidea DC. was described from Berlandier 1138. The
sheet of this number in the Museum of Vienna has one specimen
with bipinnate leaves, approaching Bidens odorata Cav. and another
with some of the principal leaves only tripartite, approaching B.
pilosa var. bimucronata. At Washington (U.S.) are two sheets of the
fine material collected by Arsene. It is remarkably close to the type
material of B. Caucalidea and might well serve as a supplementary
type for the concept represented by that name. Four of the five
specimens there have the leaves mainly bipinnate as in B. odorata
Cav. but the remaining specimen has the leaves tripartite as in the
var. bimucronata.1 Obviously the amount of foliar division is of
little value here in determining specific limits. Likewise a study of
various other specimens (referred to B. odorata Cav. or to B. Cau~
calidea DC. by different botanists), with reference to achenial shape,
size, and armature, to width of flowering heads, and to general
branching habit, reveals an astonishing amount of variation. A
form with the upper part of the main stem broken away and the
lower part profusely branched is the plant formerly described as
Bidens Deamii Sherff. B. ramosissima Sherff is probably best inter-
preted as merely a mutant form with an excessive degree of branch-
ing and the involucres finally becoming reflexed to a notably uniform
extent. A specimen collected by Seemann (Kew) is positively the
B. odorata of Cavanilles and yet in its highly branched character
displays an approach to the type specimen of B. ramosissima.
Certain specimens of Berlandier 1138 were rather under-de-
veloped in stature, somewhat pubescent-hirtellous, and had the leaf
segments more acute. These DeCandolle assumed to be another
species, confused with the B. Caucalidea material by Berlandier in
the gathering. He named them B. Daucifolia. For B. Daucifolia,
as for his B. Caucalidea, he described the rays as yellow. Since
DeCandolle's day, many (yellow-rayed) Mexican specimens of B.
triplinervia var. macrantha (Wedd.) Sherff have been determined by
students (myself among them) as B. Daucifolia DC., but recent
study of the long neglected type material of B. Daucifolia at Geneva
(Del.) and Paris (Par.) showed that B. Daucifolia is not a yellow-
rayed form. The Geneva sheet has a single small specimen, with
one flowering and one fruiting head. The ligules are a faded rosaceous
color, not yellow as DeCandolle had stated. The achenes are those
of B. odorata Cav. The Paris sheet has three small but good speci-
1 Cf. O. E. Schulz in Urban, Symb. Antill. 7: 138. 1911: "Bidens caucalideus
DC.! .... varietati bimucronato valde affinis folia pinnatisecta habet."
THE GENUS BIDENS 449
mens. Three radiate heads are present, of a faded rosaceous color.
One specimen has a head of biaristate achenes and another has two
ample fruiting heads of exaristate achenes. These specimens all
are mere variations of B. Caucalidea DC., and there is no reason to
suppose that Berlandier confused two sorts with each other. Clearly
B. Daucifolia DC. and B. Caucalidea DC. are synonymous, and
together must be equated in turn with the earlier B. odorata Cav.
Judged by standards maintained in many other genera, there
would seem to be no less than eight or ten varieties and racial formae
represented. To encumber taxonomy with a large number of addi-
tional names, when the variations are so capricious and fickle as
often to result in two or three unlike fades upon a single herbarium
sheet,1 would appear entirely unwarranted. Therefore, these vary-
ing forms, all of them intimately related to B. pilosa var. bimucronata
but tending to display more or less bipinnate leaves on most of the
individual plants, are grouped as the forma odorata of that variety.
Complicated and undesirable as the name resulting from this inter-
pretation will be,2 it is the only one that appears to accord with the
facts in nature.
The type of Cosmos tenellus H.B.K. (or Bidens Bonplandii as it
was later renamed by Schultz Bipontinus upon its transfer to Bidens)
was collected between the City of Mexico and Huahuatoca (variously
spelled Huehuetoca, Giiegiietoque, etc.) in the State of Mexico,
Mexico. A search in 1914 and again in 1924 among the type sheets
of the Humboldt, Bonpland, and Kunth set at Paris failed to reveal a
specimen with the name Cosmos tenellus, nor was there authentic
material at Berlin. The description by Kunth shows that the type
was without achenes. The bipinnatipartite foliage and the probably
rosaceous color of the ligules evidently had led him to place the plant
in Cosmos. A survey of Cosmos and Bidens at the present time indi-
cates that Kunth's extended description fits none other than the
present f . odorata of Bidens pilosa var. bimucronata. This forma, as
well as its supravening variety bimucronata, is very abundant
1 C. V. Hartman 564 (Gray) and C. A. Purpus 1544 (Calif.) are especially good
examples of this.
2 O. Kuntze (Rev. Gen. 1: 322. 1891) put forth a treatment of Bidens pilosa
in which he adopted the even more complicated and unwelcome method of pro-
posing varieties, subvarieties, and forms (formae). His name subbiternata is seen,
on carefully reading the related names, to have been used for a subvariety or group
(under B. pilosa) ranking lower than a variety but higher than a forma (thus cf.
B. pilosa a. leucantha 2. ternata f. pilosior, loc. cit.). Yet, even were the formal rank
of the name subbiternata accepted, it could not conflict with the validity of the claim
of odorata to formal rank, as subbiternata pertained to a form of B. pilosa var.
radiata, not of var. bimucronata.
450 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
throughout the region surrounding the type locality of Cosmos
tenellus. Moreover, the general aspect is often deceptively like that
of Cosmos, a fact easily explaining Kunth's reference of his type
to that genus.1
The type of Bidens inermis Wats, is matched by Pringle 1638,
5999, and 7904. All four numbers have achenes especially slender
and long-attenuate, as well as exaristate. The forma odorata is
known frequently to produce achenes wholly or in part of this very
kind, thus leaving no grounds for the retention of B. inermis as a
species.2 It may be remarked that 0. E. Schulz, in 1911, studied
some of the B. inermis material (e.g., Pringle 1638) in the Berlin
Herbarium and labeled it B. Caucalidea DC., which in turn, as al-
ready stated, is merely another synonym for f. odorata.
The grayish green or bluish green color of the herbage in the
forma odorata often is very noticeable. The Mexicans appear to
prefer this form and also the var. bimucronata proper for food. Under
the name of "aceitillo" (fide A. Dugesii 471, Gray; Wm. E. Saffordii
1391, U.S.; et al.), the young plants are boiled and eaten with pinole
and salt (fide C. V. Hartmanii 564, Gray).

1 It may be noted that several specimens collected by Brother G. Arsene in the
states of Puebla and Michoacan (U.S.) had been distributed by Arsene under the
name Cosmos tenellus H.B.K. and that these are our f. odorata.
2 The singular aspect of the fruiting heads upon typical "B. inermis" might
be taken as justifying a subformal rank under f. odorata, but the already lengthy
name B. pilosa var. bimucronata f. odorata would seem to suggest restraint in this
matter. Furthermore, some material (e.g., Edward Palmer 673, Kew) has fruiting
capitula precisely like those in the type collection of B. inermis but merely 3-5-
partite leaves as in B. pilosa var. bimucronata proper, thus displaying an overlap-
ping of characters.

The Willdenow Herbarium has a sheet of Bidens diversifolia
Willd. (ex DC.) and this sheet bears two plants. One is referable to
var. alausensis, but the other seems more like B. andicola H.B.K.
Willdenow doubtless construed them to be genetically the same,
hence his name diversifolia. It appears, however, that this was
merely a case of mixed material. Fortunately, the very definite
status and validity of the names alausensis and andicola permit us
to ignore the name B. diversifolia Willd.
In a former article (Bot. Gaz. 59: 310-311, fig. 1. 1915) I have
discussed the identity of B. valparadisiaca Colla and B. chilensis
DC. with B. alausensis H.B.K., and presented photographs of
Kunth's type of B. alausensis H.B.K. In 1924 I made a careful
reexamination of Kunth's type and of four sheets of cotype material
(Par.; Berl.) and came to the same conclusion as before. A study of
various other specimens shows that B. alausensis H.B.K. cannot
properly be regarded as specifically distinct from B. pilosa L. Thus,
for example, J. F. Macbride 2899 and 2901, at altitude of about
2,400 meters, Matucana, Peru, etc. (Field),1 have tripartite leaves
1 These and the other Macbride specimens cited were obtained by Mr. Mac-
bride, who had the matter particularly in mind on his recent South American
expedition. Of each number I have seen various duplicates awaiting distribution to
other herbaria.

and are a form1 of B. pilosa var. radiata Schz. Bip. But Macbride
2902 (Field), collected at the same place and same time as Macbride
2899 and 2901, has the foliage mostly bipinnatisect, and is very
close to or identical with various specimens of B. alausensis H.B.K.
from Chile and Ecuador.2 Macbride 2900 p.p., altitude about 2,400
meters, Matucana, Peru, March 14-18, 1923 (Field), and 3473,
altitude about 2,550 meters, Cani, Peru, April 16-26, 1923, also are
identical in habit and technical characters with B. alausensis, except
that they are taller and more robust and their foliage is more finely
cut, becoming even tripinnatisect. These are identical with A.
D'Orbigny 1234, Bolivia (Par.), labeled Bidens Scandicina var.
glabrescens by Weddell. They match also the Berlin and Paris
cotypes of B. Scandicina H.B.K., except that the latter have more
pubescent leaves with somewhat finer divisions. It is significant
that the types of B. alausensis H.B.K. and B. Scandicina H.B.K.,
here seen to be so closely connected by intermediate specimens,
were collected by Humboldt and Bonpland in the same vicinity:
B. alausensis between Alausi and Tambo de Guamote (the type
label gives merely "Alausi"), Ecuador, and B. Scandicina between
Llactacunga and Ambato, Ecuador.
It might seem at first that there is here a situation comparable
with that in B. pilosa var. bimucronata (Turcz.) 0. E. Schulz, where
the form with finely divided leaves is reducible to subordinate rank
as f. odorata (Cav.) Sherff. In such a case we should have the names
alausensis and Scandicina taking respectively formal and subformal
rank under the name B. pilosa var. radiata, giving names which
would be very cumbersome. It seems more probable that in the
present case the alausensis and Scandicina forms do not intergrade
nearly so much with B. pilosa var. radiata as does the odorata form
with B. pilosa var. bimucronata. Hence there appears good reason
for assigning B. alausensis varietal status directly under B. pilosa,
and reducing B. Scandicina to a forma under the variety.

1 In the Buchtien specimens the similarity to certain Umbelliferae, implied in
the name Scandicina, is most striking. In fact, before seeing the Sodiro (cf.
Hieronymus, Bot. Jahrb. 29: 48. 1901) and de Jelski specimens, I had not thought
to connect the Buchtien specimens with f. Scandicina, and had tentatively con-
sidered them as representing a new species. Curiously enough, I too had been
impressed with the resemblance to certain Umbelliferae, especially Musineon,
and, to a lesser extent, Chaerophyllum, and had tentatively employed a trivial
name based upon the resemblance to Musineon. In one specimen by Buchtien
(No. 811) the foliage and general habit suggest also those of Anthemis Cotula L.

THE GENUS BIDENS 455
Type specimen: Collected by Eduard Poeppig, No. 207, in rocky
and gravelly maritime places near Valparaiso, Chile, June (Del.)-
Distribution : Known only from Chile.
Specimens examined: Erik Asplund 42, Valparaiso, July 17,
1921 (Stockh.); Poeppig 207 (type, Del.: cotypes, Berl.; Hll.; Kiel;
Mus. V., etc.).
In a former article (Bot. Gaz. 76: 158. 1923), Bidens chilensis
var. Apiifolia DC. was discussed and the Berlin cotype (Poeppig
207) of that variety was treated as "an unimportant foliage form of
B. alausensis." Subsequent study of much cotype material, in
conjunction with several specimens collected by J. F. Macbride at
Matucana, Peru, revealed closer affinities of several of the original
specimens with B. pilosa var. radiata Schz. Bip. Specimens of Poep-
pig 207 were studied in collections belonging to several of the older
herbaria. Two specimens in Vienna and one in Berlin appeared
closer to var. alausensis, but the cotypes elsewhere appeared, when
studied in the light of the interesting Macbride specimens previously
described (cf. Bot. Gaz. 81: 35. 1926), to be closer to var. radiata.
The nomenclatural problem offered by the publication in 1836
by DeCandolle of this var. Apiifolia is particularly vexing, since its
publication antedated that for both the var. alausensis and the var.
radiata. An equation of the var. Apiifolia with either of these two
varieties would compel the taking up of the name Apiifolia and the
reduction of a well established name to synonymy. The intermediate
nature and ill denned status of the var. Apiifolia would make such
a course seem unwise, if not indeed impossible. Apparently the
interests of taxonomy are best conserved by employing the com-
bination B. pilosa var. Apiifolia to apply only to the form inter-
mediate between vars. alausensis and radiata, and represented by
Poeppig 207. In this case, the last two names, each certain in its
application and well supported in herbaria by illustrative material,
are left undisturbed.1

1 Concerning the intermediate nature of var. Apiifolia, it may be remarked

(-B. pilosa var. radiata).

Bip., the immature type of which (Par.) is especially well matched
by the Palmer plant, it is sufficient here to state that these specimens
are referable to Bidens brachycarpa DC. The type and cotype
specimens of B. brachycarpa DC. (Del.; Par., etc.), with their small
leaves, small heads, more or less rosaceous ligules, and small, ex-
aristate, upwardly attenuate achenes, appear widely different from
458 FIELD MUSEUM OF NATURAL HISTORY— BOTANY, VOL. XVI
typical B. pilosa L. A study of the other herbarium specimens
cited above, however, shows it to be impossible to maintain separate
specific rank for them; rather must they be given varietal rank
under B. pilosa as was done by 0. E. Schulz (loc. cit.). According
to the International Rules, the earlier varietal name calcicola must
be applied here.1 The type of the var. calcicola, Pringle 11340
(Gray), has a single pair of stem leaves present, these pinnately
5-parted, with the terminal and basal leaflets more or less definitely
3-parted; the divisions are lanceolate; the involucres are rather
densely canous-pubescent. These characters are found to be dupli-
cated in various of the specimens above.
DeCandolle appears to have attached undue importance to the
amount of scabridity on the achenial surfaces. Thus he placed
Berlandier 5 and 113, with achenes scabrous, in his new species B.
brachycarpa, but Berlandier 2220, with achenes less glabrous2 and
happening to have a taller, more corymbose habit, with the terminal
leaflets more elongate, he described separately under the new name
B. exaristata. The technical characters of flowers and fruit offer
no warrant for maintaining B. exaristata as a separate species or
variety apart from the var. caleicola. As to the somewhat taller
habit and more corymbosely or even fastigiately branched inflores-
cence observed in certain specimens (Berlandier 39, Del., Par.;
idem 2220, Del., Par.; Nelson 2111, U.S.), these seem to be merely
the result of a capricious growth. Indeed, Berlandier 800 and 2220
in the Gray Herbarium have a much more loosely corymbose in-
florescence as, in fact, DeCandolle's description states ("laxe corym-
bosa"), and thus at once remove from consideration the only charac-
ter that by some botanists might be thought important. Through
the first Berlandier specimen just cited (No. 800) an approach is
made to B. pilosa var. bimucronata (Turcz.) 0. E. Schulz, a variety
1 The Berlin Herbarium has several specimens of B. pilosa (leg. Sello et al.)
with mature achenes only 4-5 mm. long and closely simulating the var. calcicola
plants in all important respects except that they lack rays. Similarly, various
herbaria have plants of the var. radiata with diminutive, commonly pubescent
leaves and many of the fruiting heads minute, approaching the var. calcicola type
so closely as practically to efface all varietal distinctions. The Tonduz specimens
might almost equally well be regarded as of the species proper, and in fact had been
treated as that by me until the same local form appeared again during further
studies (Cooper 5814), with some of the heads radiate.
2 DeCandolle (loc. cit.) actually described the achenes as glabrous ("achaeniis
glabris"), but in two sheets of Berlandier 2220 (Del.), many of the achenes are dis-
tinctly scabrous near the apex.
O. E. Schulz (loc. cit.), evidently relying upon DeCandolle, likewise regarded
B. exaristata as having glabrous achenes. Thus he stated: ' B. exaristatus DC.
. . . ab hac varietate [B. pilosa var. bimucronata] acheniis glabris differt."

A form comparable with the var. calcicola in much the same way
that the bipinnately leaved f. odorata of B. pilosa var. bimucronata
(Turcz.) 0. E. Schulz is comparable with that variety. Indeed, of
the var. bimucronata and its form with more compound foliage (i.e.,
f. odorata}, there are found at times stunted or dwarfed specimens
which have flowering and fruiting heads diminutive enough to be
taken for var. calcicola and f. dissecta. It is therefore possible that
in some of my past herbarium determinations I may have confused
the two varieties and their respective forms to a slight extent.2

0. E. Schulz (loc. cit.) found in the herbarium of the Botanical
Garden at Berlin three sheets of Bidens material collected by Sello
(the name often spelled "Sellow" in literature), No. 607, in Brazil.
These he determined as Bidens megapotamica Spreng., although
the labels bore no data as to the locality in Brazil whence the plants
came. Sprengel's description was based upon a plant collected by
Sello at "Rio Grande" in "Brazil."1 That Schulz had not seen this
Rio Grande specimen is shown by his citing it "Sellow ex Sprengel."
In 1923 (Bot. Gaz. 76: 91) I presented these and other facts and stated
the conclusion that Bidens megapotamica was a species of Thele-
sperma and as such had been correctly renamed Thelesperma mega-
potamicum (Spreng.) 0. Kuntze (taking precedence in Thelesperma
over the synonym T. Scabiosoides Less.).
In 1926 (Bot. Gaz. 81: 252-254) I reported finding what seemed
an authentic specimen of Bidens megapotamica Spreng. in the Deles-
sert Herbarium and on the strength of that specimen, of the well
known Isostigma Peucedanifolium (Spreng.) Less., made the new
combination I. megapotamicum (Spreng.). About the same time,
but too late to prevent publication of this new combination (vide
Bot. Gaz. 83: 425. 1927), Dr. S. F. Blake reported finding the true
type of B. megapotamica Spreng. in the Schultz Bipontinus Herbarium
(Par.). This plant, as his photograph and observations showed, was
true Thelesperma Scabiosoides Less. Thus the plant of the Delessert
Herbarium was seen to be of spurious or at least erroneous determina-
tion, and my first reasoning, namely, that Bidens megapotamica
Spreng. was equivalent to and took precedence over Thelesperma
Scabiosoides Less, (thus validating the name Thelesperma mega-
potamicum [Spreng.] 0. Ktze.), was proved correct.
1 Sprengel Latinized the citation Rio Grande to read "Ad fl. magnum Amer.
austr.," evidently thinking that a Rio Grande River had been meant by Sello.
The name megapotamica would seem to emphasize this fact. A study of various
specimen labels, however, shows that Sello collected many specimens either in the
State of Rio Grande Do Sul or in the country just south, which, although shortly
after Sello's collecting separated from Brazil under the name of Uruguay, was
considered a part of Brazil when Sello collected, and may easily have been con-
sidered by him a part of the adjacent province of Rio Grande Do Sul. Thus we
read (as given by Lessing, Linnaea 6: 103. 1831): "Sellow in Brasilia meridionali
ad Rio Pardo Octbr. et Novbr. 1823"; ibid. 141, "In Monte Video Commerson
et Sellow"; ibid. 516, "Sellow in Campis ad Rio Nigro." In this connection we
may note also that DeCandolle (Prodr. 5: 634. 1836) cites for the State of Rio
Grande Do Sul four species of Thelesperma and Isostigma collected by Sello and
cited by Lessing merely as coming from Brazil.
THE GENUS BIDENS 465
This is particularly reassuring, since it enables us definitely to
eliminate from consideration the trivial name megapotamica in the
genus Bidens, where it had been placed erroneously by 0. E. Schulz
(loc. cit.), and for the one species considered here to take up the
name B. subalternans DC.
Bidens platensis Mang. was described as a hybrid between B. pilosa
L. (staminate) and "B. bipinnata L." (pistillate). A study of Miss
Manganaro's text convinced me some time ago that the plant which
had been assumed to be B. bipinnata L. was in reality B. subalternans
var. simulans. Recently I was given valuable aid in the determi-
nation of B. platensis by Professor Angel L. Cabrera of the La Plata
Museum in Argentina. In a letter he wrote to the following effect:
His numerous searches in the past for the type of B. platensis had
been fruitless. He therefore had given the type up for lost.
Recently, however, he had been entrusted with the rearrangement
of the Spegazzini collections for the La Plata Museum. Now, the
late Miss Manganaro had been a pupil of Spegazzini, and at her
death her parents sent her collections to Spegazzini. Professor
Cabrera found her collections inside an old chest, in November, 1930.
The herbarium was in great disorder, without labels or any other
indications. There were, however, several specimens of Bidens that
had been very carefully mounted, and these were "closely similar to
the original figure of B. platensis." Since no other specimens in the
Manganaro collection had been given such special care, Professor
Cabrera concluded (without doubt rightly) that these specially
mounted ones represented the type material of B. platensis. He
lent two of the supposedly type specimens for study and they are
now before me. Both are typical B. subalternans.

At times Bidens subalternans is found with the leaves delicately
2-3-pinnatisect and the segments linear, even narrowly so. For a
number of years, when making herbarium determinations, I included
such forms under the species proper without distinction. Only more
recently have I distinguished them as var. simulans. In some
cases they suggest B. bipinnata L. so strongly as to create confusion.
In other cases they display a slight approach to B. exigua Sherff.

Occasionally a South American specimen of Bidens is found with
the general aspect of B. pilosa L., but with the fruiting heads as
in the closely related B. subalternans. A close inspection shows that
the only difference from typical B. subalternans is in the once-pinnate
(instead of twice-pinnate) leaves.

Distribution: Widely distributed throughout the West Indies; in
State of Yucatan, Mexico, and throughout northern South America
to central Peru and the states of Matto Grosso and Ceara, Brazil;
has been collected (T. Thomson) also in northwestern Himalaya,
British East India, where doubtless adventive; recently established
in the Hawaiian Islands.
Specimens examined:2 Ed. Andre 151, La Guayra, Venezuela,
November 25, 1875 (Field; N.Y.); anon., St. Croix (Cop.); Charles
1 The type sheet gives Havana for the locality, but Bonpland's private dupli-
cate sheet gives "Guanayacoa" (Guanabacoa; across the small bay from Havana)
and so does Kunth's original description.
2 Many of these specimens were listed in the manuscript before it was decided
to maintain any varieties of B. Cynapiifolia, hence possibly a very few are included
which belong to var. portoricensis or var. tennis.

Humboldt sent some of the type material of Bidens riparia to
Willdenow, who labeled it B. Ambrosioides. From the Willdenow
Herbarium (Berl.) Schultz Bipontinus obtained a leaf and some
achenes, which are preserved in a packet in his private herbarium
(Par.) and are likewise labeled B. Ambrosioides ("Willd. herb. no.
15031 fol. 1 ... "). Kunth's name B. riparia takes precedence
over Willdenow's, having received earlier publication.

Brandegee's original description, like several others of his Bidens
descriptions, was carelessly drawn. The exterior involucral bracts
are linear, not "linear-lanceolate." The terminal leaflet is larger,
not "much smaller" than the lateral ones. The achenes are almost
uniformly shorter than he says, very few being "20-25 mm." long.
0. E. Schulz (loc. cit.), in reducing this form to varietal rank
under B. riparia, differentiated the two forms on the basis of fruit
characters, but an examination of many specimens of each form shows
that the only genuine difference is in the foliage. B. refracta Bran-
deg. has tripartite leaves while B. riparia H.B.K. has bipinnate or
tripinnatisect leaves. This difference Schulz seems to have over-
looked. Indeed, he even refers to B. refracta, Tonduz 13618, a plant
identical in foliage and other parts with the type and Bonpland co-
type of B. riparia.1
Several years ago, on having examined 22 collections of the
refracta form and failed to find more than one approach in foliage to
that of B. riparia, I concluded (Bot. Gaz. 64: 35. 1917) that "the
probabilities are strong that B. refracta and B. riparia are entirely
distinct species." Since then, I have seen several other foliage
intergradations. Furthermore, we have the important consideration
that in numerous species of Bidens the foliage is known positively
to vary from tripartite (or even simple) to bipinnate or tripinnatisect.
Thus all attempts to defend a specific segregation of the tripartite-
1 Schulz's confusion of the refracta with the riparia forms is shown further by
certain of his determinations at Berlin. For example, he there referred not only
Tonduz 13618, but also Bernoulli & Carlo 1384 and Gaumer 2498 to refracta. All
these are riparia proper.

leaved form would seem to be futile and the varietal rank proposed
for B. refracta Brandeg. by 0. E. Schulz is here adopted.

Peru, however, is unquestionably erroneous. No specimens are
known from Peru. Furthermore, the Pavon specimens cited (Boiss.),
which from a comparison of other Pavon herbarium specimens

A species with lower part of plant having aspect usually re-
sembling that of Bidens pilosa L. The bipinnatifid upper leaves,
however, as also the few long peduncles and the radiate flowering
heads, distinguish it easily from that species. Occasionally the
leaves, all or nearly all, are bipinnatifid, giving the plant a very
different appearance. Baker described the ligulate florets as being
orange-colored, but a number of dried flowering heads observed in
herbaria appear to have the ligules more of a reddish brown or
cinnamon color. Fiebrig, on the labels for his No. 679, describes the
ligules as fire-red and the disc florets as brown. Hassler, on labels
for his No. 4253, describes the ligules as dark purple or obscurely
orange-colored. We may note, further, that long before Baker's pub-
lication of Bidens Gardneri, Schultz Bipontinus had designated the
Weddell plant (in herb.) as Bidens rubra, evidently for the very
reason that its rays were red.
The mature fruiting heads are noticeable for the conspicuous
retrorse barbs of the achenes, these barbs suggesting strongly the
teeth of a comb.

Distribution: State of Minas Geraes, Brazil.
Specimens examined: Saint Hilaire 1196 (type, Par.).
In general habit B. brasiliensis resembles simple-leaved plants of
B. Riedelii Baker and B. Chodati Hassler. It differs from the former
in its more numerous heads, its lack of ray florets, its elongate,
aristate achenes, etc. ; from the latter, in its wider and more rhombic
leaves, more numerous heads, smaller involucres with much more
nearly glabrous and less numerous bracts, etc. The type had been
collected by Saint Hilaire in two portions representing separately
the lower, leafy stem and the branched, fruiting top. Both of these
are taken as the basis for the description.

490 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
Specimens examined: Ehrenberg 356 (type material: Berl., 2
sheets; Par.); idem 386, eodem loco (Berl.); C. G. Pringle 6924, alt.
2,850 meters, granitic ledges, Cerro Ventoso above Pachuca, August
18, 1898 (Berl.; Boiss.; Cam.; Del.; Field; Kew; Mo.; Mun.; N.Y.;
Par.; Phila.; Mus. V.; U.V., etc.).
The type of Bidens angustissima is matched very well by Schultz
Bipontinus' type of the var. Linifolia, except that the latter has only
simple leaves, while the former has tripartite leaves. Klatt, in pub-
lishing the description of his B. Linifolia, described the heads as dis-
coid, but that rays were present on at least the Paris material is
shown by Schultz Bipontinus' label, in his own handwriting, which
reads, "achs. rad. calva. . . . ' Furthermore, Pringle collected
many fine specimens of the simple-leaved form, and these all show
orange-yellow rays, about 8 on each head. The only difference to
be found between the two species is the questionable one of foliage
(cf. Sherff, Bot. Gaz. 64: 34. 1917).
At Gray Herbarium there is a single sheet (Coulter 375, Mexico)
with three slender but well developed specimens; the largest one, at
the left, matching the type of B. angustissima, and the other two, at
the right, matching the type of B. Linifolia. From these it is evident
that the simple-leaved form does not merit higher than varietal rank.
The type material of Coreopsis linearifolia DC. (leg. Keerl, Tla-
pujahua, Mexico; Del.) I have not seen. I rely upon the determina-
tion "Bidens angustissima H.B.K." communicated by Dr. S. F. Blake
(in lit.), who made a study of the material in 1924, l also the
fact that DeCandolle classified his species among those having
undivided leaves.

Asa Gray (Proc. Amer. Acad. 19: 15. 1883) carefully considered
this species, but retained it in Coreopsis, the taxonomic distinctions
between which and Bidens he admitted frequently in his writings to
be highly artificial. It is interesting to note, however, that Schultz
Bipontinus had given, previous to Gray's observations, the names
Bidens Coreopsidioides (not B. Coreopsidis as in Gray, loc. cit.) and

Bidens Schaffneri to specimens of this species sent to the Gray
Herbarium and to the Berlin Herbarium.
The type (Berlandier 1030) is matched well by the type of Bidens
sarmentosa Greenm. (Pringle 11486) and that of Bidens alpina
Brandeg. (Purpus 1648 — not 1684 as erroneously printed in Brandeg.,
loc. cit.). The general habit suggests strongly that of Anthemis
(A. arvensis L.) , whence the specific name. I have seen two old speci-
mens in the herbarium of Pavon (Boiss.) from Mexico, which were
evidently cultivated forms belonging here. The larger one is more
than 3.6 dm. high; the smaller one bears a fruiting head with achenes
up to 8 mm. long and having naked, variously spreading or even
somewhat reflexed aristae 1.5-2 mm. long. These are the Bidens
bipinnatifida Herb. Pav. (nee aliorum).
The varying treatments accorded this species have been dis-
cussed in earlier papers (Sherff, op. cit., 1913, 1915, and 1923).
Recently Bitter has published the new name Bidens Purpusorum
Bitt. & Petersen for a plant the ripe achenes of which were collected
in 1908 by C. A. Purpus in fields in the vicinity of Esperanza,
Vera Cruz, Mexico, and sent to the Bremen Botanical Garden
under the name of Bidens grandi flora Balb. In the herbarium of
the University of California are two specimens collected by Purpus
and bearing field data essentially similar to those given by Bitter.
The first was collected at Esperanza in August, 1907, not "1908,"
and matches Bitter's description well. The second was collected at
Esperanza in 1909, and distributed under the name of "Bidens
pilosa Linn.? Form." It is Purpus 3634. This second plant differs
in being more branched and in having merely 3-5-parted leaves, not
2-3-pinnatifid leaves.1 Both forms have most of the achenial aristae
retrorsely barbed, but in this and other respects are connected with
typical Bidens Anthemoides by a large number of herbarium speci-
mens examined.
Similarly, the specimens cited above (vide sub Hort. Bot. Hauni-
ensi), raised at the Botanical Garden of Copenhagen from the achenes
of the type material of Bidens Purpusorum (Cop.), are found to be
referable at once to Bidens Anthemoides.
The type material for B. Anthemoides, B. sarmentosa, and B.
alpina was in each case the more common, small, alpine form, 0.5-2
1 In a number of species of Bidens a strong degree of polymorphism is known
to occur among the leaves; for example, B. aurea (Ait.) Sherff, B. triplinervia
H.B.K., B. andicola H.B.K., B. Chrysanthemifolia (H.B.K.) Sherff, and B. squar-
rosa H.B.K. The difference in the leaves, therefore, does not appear to be of much
importance in this case.

dm. tall. Taller forms are sometimes found, the taller of the above-
mentioned Pavon Herbarium specimens being an example. The
plant collected by Henry E. Seaton, No. 272, was over 4 dm. tall.
The plants cultivated in Bremen from achenes sent by Purpus grew
about 5 dm. tall. An exceptional specimen by Schiede from Tepeya-
hualco (Berl.) measures over 5.7 dm. in height. In 1917, Professor
H. M. Hall of the University of California sent me from the botanical
garden of that university several specimens of this species for deter-
mination. He wrote: "It has been in our botanical garden for a long
time without name .... It is rather attractive and is being used
to some extent as a bedding plant." The largest specimen measured
about 4 dm. high, and many of the immature achenes had aristae
retrorsely barbed.1 The occasional presence here of retrorsely barbed
aristae in a species usually lacking them demonstrates again the
impracticability of using the presence or absence of such aristae as a
distinguishing character for Bidens and Coreopsis (cf. Sherff, Bot. Gaz.
59: 307. 1915). For 147a. Bid ens Muelleri Sherff, see p. 645.

as already seen in many other cases, plants of the same collection are found to vary
decidedly in the matter of achenial aristae.

For many years the identity of the South American Bidens andi-
cola has been obscured by the great multiplicity of foliage forms
encountered. Weddell, as early as 1856 (Chloris And. 1 : 70) described
it as a polymorphous plant ("Plante polymorphe et tres repande dans
la chaine, mais presque exclusivement alpestre"). Later, Otto
Kuntze, who like Weddell had collected in South America, com-
mented upon the variability of the leaves ("Eine robuste Art mit
einfach oder mehrfach ternatisecten Blattern, mittelgrossen gelben
Strahlbliithen, ziemlich grossen Bliithenkopfen, ausseren zottig
behaarten Involucralbracteen, etc., aber in Bezug auf Blattheilung
wie manche andere Bidens-Art sehr variabel" ; Rev. Gen. PI. 3, pt. 2:
136. 1898). In herbaria the numerous foliage forms are seen to
simulate corresponding forms of B. triplinervia H.B.K. (B. humilis
H.B.K., B. Crithmifolia H.B.K., etc.), and this has led often to con-
fusion between the two species. Some years ago I was enabled,
through the courtesy of Dr. Otto Buchtien (cf. Sherff, Bot. Gaz.
76: 151. 1923), to study a great number of specimens collected by
him and displaying a wide range of variation. From these (Field)
and many others, totalling more than three hundred specimens, the
descriptions for B. andicola and its varieties are drawn. It was
found that sometimes, in poorly developed material, distinction from
B. triplinervia or its varieties is apparently impossible, but that in
well developed material the distinctions are usually very definite, B.
andicola being coarser, its thicker heads having commonly about
eight instead of commonly about five rays, etc. B. andicola has the
paleae shorter than the mature achenes and even this character alone
separates it from the surprisingly similar aggregation of Mexican
forms of B. triplinervia (Purpus 1547, 1548, 2637, 4135, 5089, 5620;
Rose & Painter 6666, 7949; Pringle 4915; E. W. Nelson 3220, etc.)
that in late years have passed erroneously under the name B. Dauci-
folia DC. In the latter the paleae are usually very blackish above
and commonly surpass the mature achenes.
The type sheet of B. fruticulosa Mey. & Walp. in Berlin bears
two small specimens collected by Mey en in April, 1831, about
Tacora, Peru. The leaves are undivided, ovate to oblanceolate,
and only about 1 cm. long, the heads 6-8-ligulate. The plants
match very closely a certain form found among the Buchtien plants

already cited (No. 4305), and thus are seen to be merely an extreme
form of B. andicola.
As stated in a former article (Bot. Gaz. 85: 2. 1928), Grise-
bach's B. Cosmantha var. diversifolia was described as having the
lowermost leaves ternatisect, the others entire, elliptic-oblong,
sharply serrate. It came from the Province of Catamarca, Argen-
tina. The Catamarca plants studied by Grisebach had been collected
by F. Schickendantz (Griseb. op. cit. 3). A good specimen of F.
Schickendantz 200, from Catamarca and bearing the determination
B. Cosmantha var. diversifolia Griseb., is extant in the Berlin Her-
barium. It is merely B. andicola H.B.K.

Occasionally a form of B. andicola is found with the leaves highly
compound and the achenes strongly narrowed above, somewhat like
those of Cosmos. If it were not for various connecting forms this
would seem to be specifically distinct. Kuntze, who collected speci-
mens of it, referred at least one of them, a plant from Cochabamba,
Bolivia (N.Y.) to B. andicola, naming it var. decomposita. In a care-
less moment he named a precisely identical form collected between
Cochabamba and Rio Juntas, Bolivia (N.Y.) B. grandiflora var.
breviloba, although B. grandiflora ( = B. serrulata} is a Mexican species
not known to occur in South America.
To Kuntze's variety decomposita must be referred Bidens ma-
crantha Griseb., founded on a plant by P. G. Lorentz, No. 316,
alpine pastures near La Cie"naga, Argentina. The type is extant in
good condition (Berl.). Although lacking mature achenes, it matches
very closely the Bolivian specimens of var. decomposita, except in the
unimportant respect that it has somewhat larger rays.

Grisebach's type of B. andicola var.Cosmantha was P.O. Lorentz
1526, La Cie'naga, etc. Identical material was collected by Lorentz
under Nos. 540 and 5406 (Granadillas near Yacatula, etc.). These
Lorentz specimens are connected with B. andicola H.B.K. by too
many intermediate forms to permit their being regarded as specific-
ally distinct. They may best be considered as a variety of B. andi-
cola, more or less distinguished from the species proper by the tall,
slender habit, by the leaves more dissected (but less so than in var.
decomposita 0. Ktze.) and with outlines suggesting those of celery
(Apium graveolens L.), also by the (typically) larger flowering heads,
which when fully expanded reach a diameter of 6-7 cm.

In 1916, Otto Buchtien, the eminent South American collector,
courteously undertook to secure for me as wide a range as possible of
specimens of Bidens from South America. His collections since then,
as well as his earlier collections, all mainly from Bolivia and Chile,
have been received and deposited in the Herbarium of Field Museum.
Not only do some of them throw great light upon heretofore difficult
points as to the variations of certain species, but two of them were
found to be apparently new to science. One of these was described
under the name B. pseudocosmos. The other was at first regarded as
representing a new species, B. Buchtienii. Studies of the more
recently collected specimens have shown indubitably that the B.
Buchtienii plants are merely a subligulate form of B. andicola var.
Cosmantha.1
Bidens andicola var. d. tarijensis Sherff, Bot. Gaz.
85: 14. 1928.
Folia plerumque indivisa, anguste vel late oblongo-linearia,
interdum 1-5-lobata vel 3-5-partita, segmentis linearibus.
Type specimen: Collected by Karl Fiebrig, No. 3460, Tarija,
Bolivia, March 9, 1904 (Berl.).
Distribution: Southern Bolivia.
Specimens examined: Fiebrig 3004a pro parte, Tarija, in 1904
(Berl.); idem 3460 (type, Berl.); idem 3461 pro parte, alt. 3,200
meters, Calderillo, March 22, 1904 (Berl.).
The specimens cited for the var. tarijensis (and its f. dissecta,
below) come from the little known territory in the extreme southern
part of Bolivia, close to the Argentine boundary. They are graceful,
mostly glabrous plants, growing up to a meter in height. They have a
habit more characteristic of B. triplinervia H.B.K. (with which they
were at first confused by me), but the heads are rather uniformly 8-
rayed, as in B. andicola. The variety proper is seen to be comparable
with the var. hirtella of B. triplinervia. In var. tarijensis, however,
1 Recently Buchtien has reported (in lit. March 27, 1932) that B. andicola
(meaning var. Cosmantha in particular) has rays often 4 cm. long, but usually 3 cm.,
and as short as 2 cm. only on very dry spots of ground. He reports further that the
Buchtienii forms are always radiate but with rays only 2-3 mm. long. He has
"never seen plants which form a transition from the one to the other." For
practical purposes of identification, it may be remarked that dried herbarium
specimens of f. Buchtienii often appear entirely discoid.
504 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
there is observed the very strong tendency to produce a form with
the leaves divided into 3-5 elongate-linear segments. This form
(f . dissecta) is very different in general habit from other known forms
of B. andicola with compound leaves.1

80: 380. 1925.
A specie differt: saepius annua, altior (usque ad 8 vel 10 dm.
alta), minus ramosa et magis attenuata; capitulis ad anthesin sub-
radiatis, minoribus, tantum circ. 5 mm. latis et 5-7 mm. altis, achae-
niis gracilioribus.
Type specimen: Collected by Gustave Mandon, No. 48, in
uncultivated places at altitude of 2,650-2,680 meters, San Pedro,
Bolivia, March, 1859 (Boiss.).
Distribution: Bolivia and northernmost Argentina.
Specimens examined: Otto Buchtien 9105, alt. 3,200 meters,
Unduavi, North Yungas, Bolivia, October, 1931 (Field) ; P. G. Lorentz
& G. Hieronymus, cattle ranches at foot of Nevado del Castillo,

44 pro parte, San Pedro, Bolivia, March, 1859 (Boiss.; Mus. V.);
idem 48 (type, Boiss.: cotypes, Brit.; Kew).
Mr. Gustave Beauverd, in 1919, had referred my type doubtfully
to a variety of B. pilosa L. The fruiting heads, however, are more
those of B. andicola. Mandon 44, collected at the same time and
place, offers several transitional forms that connect this variety
satisfactorily with typical B. andicola. In fact, the Boissier Herba-
1 We may note an instructive specimen, K. Fiebrig 3459, alt. 2,800 meters,
Tarija, Bolivia, March 22, 1904 (Berl.)- This was collected the same day as the
Calderillo plants (No. 3461), at a slightly different altitude in a nearby locality.
Its leaves are tripartite and more as in normal forms of B. andicola.

Bidens affinis Kl. & 0. was described from specimens raised
from seed sent by E. Otto. A number of good specimens are in
the older herbaria (Herb. Bernhardi in Mo.; Mus. V.; Par.; etc.).
Specimens obtained in August, 1841, at the Strasburg Botanical
Garden (Hort. Argent.) and elsewhere from seed sent from Berlin
(where Klotzsch was Keeper of the Royal Herbarium, fide Pritzel,
Thes. 165. 1872) are in the private herbarium of Schultz Bipontinus
(Par.). These were determined by him as B. triplinervia H.B.K.
O. E. Schulz (in Urban, Symb. Antill. 7: 143. 1911) likewise equates
B. affinis with 5. triplinervia. In 1914 I compared the B. affinis
specimens with the type and Bonpland duplicate of B. triplinervia
(Par.) and found them identical.2
Asa Gray (Proc. Amer. Acad. 22: 429-430. 1887) suspected B.
triplinervia of being a form of B. heterophylla Ort.; i.e., of B. aurea
(Ait.) Sherff. The two species do actually resemble each other in
1 Here may be mentioned C. G. Pringle 7895, alt. 2,850 meters, Sierra de
Pachuca, Hidalgo, Mexico, September 14, 1899 (U.S.); idem 7908, alt. 3,000 meters,
eodem loco, October 6, 1899 (Gray); idem 8255, eodem loco, October 5, 1899 (Berl.;
Boiss.; Brit.; Can.; Cam.; Del.; Field; Gray; Kew; Mun.; Mus. V.; Par., 2 sheets;
Petrop.; Phila.; U.S., etc.). These are tall, robust forms, appearing at first as if
abnormal forms of Bidens serrulata. Most of the specimens have simple leaves
and these vary greatly in outline (from ovate-lanceolate to rotund) and hispidity
Cdensely hispid to glabrous). No. 7908 has the ovate, simple leaves very incisely
toothed with about 5-7 long teeth on each side, giving the same pectinate appear-
ance noted by Schultz Bipontinus in certain specimens of Mandon 50 from Bolivia.
In a number of cases, however, the foliage is fairly typical for B. triplinervia.
Whether the bizarre vegetative variations observed among these Pringle
plants from the upper slopes of Sierra de Pachuca are indicative of hybridization
with one or two neighboring species can only be surmised at this time.
2 The Berlin Herbarium contains the two sheets, already cited, of fine material
collected near Angangueo, Michoacan, Mexico, October, by Schiede, also several
garden specimens cultivated in 1833 at Berlin, doubtless from seed of the Schiede
specimens.

their simple-leaved states, but B. triplinervia's longer achenes are
very distinctive.
Bidens pedunculata Phil, was based upon Frederick Philippi 217,
Sibaya, Province of Tarapaca, Chile. I have not seen the type,
although the first above cited specimen, from Tarapaca, may be
from the original collection. Reiche (Fl. Chile 4: 102. 1905), who
without doubt has studied the type, equates B. pedunculata with B.
serrata Pav., but this latter has more slender leaves than called for by
Philippi's description ("foliis inferioribus .... ovato-lanceolatis")
and is better referred to var. hirtella.

Type specimen: Collected by Alexander Humboldt and Aime
Bonpland, probably at Quito, Ecuador, 1799-1803 (Par.).
Distribution: Colombia, Ecuador, and Peru.
Specimens examined : Bro. Ariste-Joseph A42, Bogota, Colombia,
1916 (U.S.); M. T. Dawe 302, sabana or plain of Bogota, Colombia,
communic. 1916 (Kew); Humboldt & Bonpland, probably at Quito,
Ecuador, 1799-1803 (types of Bidens hirtella H.B.K. and B. pro-
cumbens H.B.K.; Par.); iidem, Quito, eodem tempore (Par.); Ruiz,
Pavon, and Dombey 977, Peru, 1788 (Del.; type of Bidens serrata
Pav. ex DC.); J. Triana 1374 pro parte (Par., cum var. macrantha
commixt.).
The type locality of B. hirtella H.B.K. and of B. procumbens
H.B.K. was not definitely known to Kunth. In the case of the
former, he surmised (H.B.K. loc. cit.) that the plant had grown with
B. triplinervia H.B.K., which was known to have been collected in
Mexico ("prope San Augustin de Las Cuevas et urbem Mexici").
In the case of the latter, he surmised that it had grown near Jalapa
("Xalapa"), Mexico. An extra sheet of original material matching
the type of B. hirtella and of the identical B. procumbens was in the
Bonpland Herbarium, which was given later to the Paris Herbarium.
This was clearly of the same collection as the two types mentioned.
It had been labeled (by Spach, fide L. Anfrayi coram me in mense
510 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
Augusto anno 1914) B. procumbens, and had come from Quito,
Ecuador. Without doubt the types of B. hirtella and of B. pro-
cumbent, which had upon their labels no data as to locality
(except "Ame'rique Equatoriale"), came from the same locality,
Quito, Ecuador.
In a former paper (Bot. Gaz. 80: 383. 1925), I have treated B.
triplinervia as having two sets of forms with divided leaves (var.
mollis and var. macrantha), and one set with undivided leaves (the
species proper). From this last set may properly be segregated
the forms with slender leaves as var. hirtella. Kunth described the
leaves of this variety as lanceolate, but they are variously linear-
lanceolate, widely linear-oblong, or narrowly oblong-lanceolate.
The affinity with B. triplinervia is evidenced by the mostly 5-rayed
heads, which probably alone distinguish the variety from the corre-
sponding var. tarijensis of B. andicola H.B.K.
To var. hirtella must be referred B. serrata Pav. ex DC. The
type (No. 977 of the Ruiz, Pavon, and Dombey expedition, Peru, in
1788; cf. Lasegue, Mus. Bot. Deless. 244-247. 1845) is extant in the
DeCandolle Prodromus Herbarium (Del.). It lacks flowers, as
stated by DeCandolle, but has some leaves undivided and lanceolate
or narrowly oblong, others somewhat incised or lobed at the base.

As stated in an earlier paper (Bot. Gaz. 61: 500. 1916), the two
type specimens from which Kunth described B. Crithmifolia and B.
Delphinifolia are still extant in good condition (Par.). Both are from
Ecuador l and differ only in the slightly diverse foliage. The immature
type of B. Crithmifolia is matched exactly by J. J. Triana 1374 pro
parte (Par.), a specimen collected near Bogota, Colombia, which is
superior in showing not only flowering heads but also numerous
achenes. These achenes are mainly 2-aristate, but some are 3-aris-
tate and so agree perfectly with achenes of B. Delphinifolia.2 Fortu-
nately, I have found another specimen by Triana of the same number
in the British Museum of Natural History, and this shows the
slightly different foliage of B. Delphinifolia, for which it might well
be taken to represent a supplementary type.
1 Kunth (loc. cit.) expressed uncertainty as to the locality whence B. Del-
phinifolia had come, but Bonpland's duplicate specimen (Par.) has the original
label marked "XI Quito."
2 It is interesting to note that the mature head on the type of B. Delphinifolia
has at least one achene that is 2-aristate, showing no indication of a third awn's
ever having been present (cf. H.B.K. loc. cit., "triaristata").
518 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
There is great variation in foliage. Triana 1375 (Brit.) shows one
plant with leaves tripartite, the leaflets being incisely dentate, and
another plant with the simple, ovate-lanceolate leaves of B. tri-
plinervia proper. In fact, the sheet of Triana 1374 in Paris bears
another specimen (besides that cited above) which has similarly
simple, ovate-lanceolate leaves; and still another specimen of
Triana 1374 at Paris has the slender, undivided leaves of var.
hirtella. Evidently Triana did not differentiate in the field between
the two types of simple leaves or between these and the finely
divided ones.
In 1914, on comparing the simple-leaved spontaneous state
(Triana 1374 pro parte and 1375 pro parte, also Goudot, ditches,
Fontibon, February 20, 1844) with the mature B. affinis and imma-
ture B. triplinervia material, I was impressed with their similarity.
I searched, but in vain, for any authentic material of B. affinis mani-
festing the divided leaves so much more common than undivided
ones on B. Crithmifolia. Later, I was permitted, through the kindness
of Dr. Alex. Zahlbruckner to study the large set of Bidens specimens
in the Natural History Museum of Vienna and found three more
sheets of the original B. affinis material. These display numerous
gradations from the typical undivided, lanceolate leaves of B. affinis
to the bipinnate leaves characteristic of B. Crithmifolia. The
plants are a little larger, but this doubtless was due to cultivation.
The floral and achenial characters are identical. The plants with
decompound foliage (B. Crithmifolia, B. Delphinifolia, etc.) are,
therefore (cf. Bot. Gaz. 76: 156. 1923), not more than varietally
distinct from B. affinis Kl. & 0. and, hence, from its equivalent,
B. triplinervia H.B.K.
Because of the great rarity of the form with undivided, ovate-
lanceolate leaves (B. triplinervia proper) and the evolutionary
detachment from this simple-leaved form that the various forms with
divided leaves manifest to-day, it seems wisest to associate without
distinction all the cut-leaved forms, except vars. mollis and nema-
toidea, under the earliest varietal name, var. macrantha. Accordingly,
this has been done in the present treatment.
B. humilis H.B.K., the type of which also came from Ecuador,
is not varietally distinct from B. Crithmifolia and therefore reduces,
likewise, to var. macrantha (cf. Weddell, Chlor. And. 1: 69. 1855:
"Le B. Crithmifolia H.B.K. et le B. delphinifolia H.B.K. sont tres
voisins de cette espece B. humilis, dont ils ne sont meme peut-etre
que des formes a feuilles moins divise"es, et a lanieres plus allonge"es";

also Jameson, Syn. PL Aequator. 2: 117. 1865: "a B. crithmifolia et B.
delphinifolia vix distincta videtur."). B. consolidaefolia, described
by Turczaninow from Jameson 693, collected at Quito, is a form
with finely divided, very pubescent leaves (cf. Turcz. Ann. Bot.
Syst. 5: 225. 1858: "Accedit ad definitionem B. humilis H.B.K. sed
ligulae duplo majores, achaenia minime scabra et forte laciniae folior.
angustiores.").
B. decomposita var. hirsutior was described by Clarke (cf. Bot.
Gaz. 61: 500. 1916) from a single specimen collected by him at an
altitude of over 2,200 meters, in the Nilgiri Mountains of British
East India. Later he informed J. D. Hooker (cf. Fl. Brit. Ind. 3: 310.
1881) that he supposed it to be some cultivated plant. Hooker
admits having seen no specimen of it, but it happens that Clarke's
original specimen ("11207. . . 23 March 1870 . . . coll. C. B. Clarke.") was
sent to Kew Herbarium in 1877 and is still there in good condition.
The plant is very different from Bidens decomposita Wall., but its
villous, finely divided leaves match fairly well Jameson 693, the type
collection of B. consolidaefolia Turcz. It matches also a number of
other South American specimens of B. triplinervia var. macrantha.
In the same region of India Dr. Watt collected material (Watt 2160)
that agrees with Clarke's specimen except that it is minutely pubes-
cent as to leaves and glabrous as to stems. Still more specimens
from this region occur (e.g., Thomson, Eclipse Exped., Nilgiri Hills,
December, 1871, determined on sheet as "Bidens humilis H.B.K.,"
in Kew; and R. H. Beddome 4511, "introd.? a common weed,"
Nilgiri Hills, in Brit.), some of them glabrous and some pubescent
but all indistinguishable from B. triplinervia var. macrantha. A
study of these specimens, all collected in the same region at about
the same time, and by two of the collectors suspected of being
introduced, shows beyond doubt that they were merely forms of B.
triplinervia var. macrantha carried, perhaps in ballast, from South
America to the southwest shores of British East India.1
At times, dwarfed, immature forms of B. andicola H.B.K. decep-
tively resemble the var. macrantha and thus frequently have been
confused with it in herbaria. B. serrulata (Poir.) Desf. (B. grandi-
flora Balb.) appears really distinct from var. macrantha, despite the
implication of Dr. Otto Kuntze's name B. grandiflora var. humilis
(cf. 0. E. Schulz in Urban, Symb. Antill. 7: 139. 1911: "Sine dubio
pleraque specimina ab 0. Kuntze I.e. commemorata ad species
1 Cf. Fyson (Fl. Nilgiri and Pulney Hill-tops above 6500 feet 1: 237. 1915),
who, though omitting historical details, lists B. humilis from South America as an
introduction into the Nilgiri Hill region.
520 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
propinquas pertinent," a criticism justified also by Kuntze's incor-
rect association of Clarke's var. hirsutior with B. pilosa L. Kuntze's
combination derived, perhaps, from the fact that in certain localities
of Mexico (e.g., Mt. Orizaba and Sierra de Pachuca) a few plants of
var. macrantha (i.e., of B. humilis H.B.K.) are found with a more
robust growth habit, suggesting somewhat that of B. serrulata (Poir.)
Desf. (i.e., of B. grandiflora Balb.).
The several original specimens of B. Artemisiaefolia Poepp. &
Endl. still extant (Mus. V.; Berl.) are the form of var. macrantha
with tomentose pubescence and 2-3-pinnatifid leaves. They match
rather closely the original material of B. decomposita var. hirsutior
and B. consolidaefolia. They were collected by Poeppig, No. 1378,
in "Peruvia subandina. In montibus apertis calidis ad Cassapi.

The type of Bidens mollis Poepp. & Endl., Poeppig 1377, was
found growing with the type material of B. Artemisiaefolia (referred
above to B. triplinervia var. macrantha). Its achenes were immature
and the leaves tripartite. In pubescence, floral characters, and
general habit it was similar to the B. Artemisiaefolia specimens.
The peculiar outline of the leaf divisions, however, would seem at
first to suggest B. andicola more strongly. Spruce 5047 matches
the B. mollis type very closely. Spruce 5049 (Brit.) and 5894 (Gray)
match Spruce 5047 minutely except that they show the leaves finely
divided, as in B. Artemisiaefolia. These and other similar consid-
erations show beyond all doubt that B. mollis belongs to B. tripli-
nervia, is merely a foliage form, and, as such, should be accorded
no higher than varietal rank.

singular foliage form and photographs (my photograph No. 341) were
distributed to several herbaria. Recently I have been sent the
Viereck plant, collected in the same locality and revealing similar
characters. On both specimens the segments of the very numerous
and pinnately or more often bipinnately parted leaves are strikingly
thread-like. Otherwise the plants are like those of the very common

The general habit, so far as can be inferred from the single

and B. triplinervia var. macrantha. The foliar segments are especially
acute, however, and the unbarbed achenial aristae should render
distinction easy.

Dr. S. F. Blake examined Bertoloni's type which he found (July
21, 1925) in the Bertoloni Herbarium at Zola Pedrosa, near Bologna,
Italy.1 He states (in lit.) that he is satisfied that my determination
of Maxon & Hay 3690 as B. canescens Bertol. is correct. Bertoloni's
description was so full and detailed that the topotypes collected by
Maxon and Hay, and by Salvin and Godman, could anyway be
identified with his species without the slightest room for doubt.
Authentic specimens with mature achenes are much to be desired,
that the relationship of this species with its closest ally, Bidens
andicola var. decomposita 0. Ktze., may be investigated more
extendedly.

In most herbarium determinations of this species (cf. Bot. Gaz.
85: 11. 1928), I have employed the widely accepted name Bidens
THE GENUS BIDENS 529
grandiflora Balb., a name going back to 1812. The trivial name
serrulata was employed by Poiret one year earlier, and must be taken
up. Certain authentic specimens of Poiret's species are extant at
Paris, where this plant once was cultivated for at least several years.
One of them ("Du Jardin des Plantes de Paris. 5 Aout 1813") was
photographed by me. They are specifically the same as the plants
cultivated by the younger Jacquin in 1810 from seed sent from Paris
(Mus. Hist. Nat., located in the Jardin des Plantes), under the name
Bidens quinqueradiata Zea and named by Jacquin, Coreopsis diversi-
folia. They are matched specifically also by the type illustration
of Cosmea lutea Sims.1
The cultivated specimens found in herbaria are mostly lower,
more delicate, and less erect, giving an illusory appearance of dis-
similarity to the spontaneous form. Poiret's description was based
upon one of Desfontaines' specimens. Like many of the descriptions
written in those days, it was inadequately drawn. The fruit characters
were omitted. We read that the plant described is small, with
petioles and lower part of stem pilose, also with ovate leaves. These
last were not described as compound.
DeCandolle (loc. cit.), evidently relying solely upon Poiret's
description,2 maintained B. grandiflora apart from B. serrulata (Poir.)
Desf . The Index Kewensis (1 : 617. 1895), however, equates Coreopsis
serrulata Poir. and Bidens grandiflora Balb. Furthermore, we are
bound to consider the very careful and extended description of the
Poiret species drawn up by Cassini (loc. cit.) when publishing the
new combination Kerneria serrulata. Cassini had been in Paris, at
the center of Desfontaines' and Poiret's activities. He amplified his
description from living material growing in the Royal Garden of
Paris, where Desfontaines had worked. His description fitted very
well the average plants of B. grandiflora Balb.
Upon the grounds of priority the name B. serrulata takes pre-
cedence, going back to some time in the year 1811 prior to November
29,3 while B. grandiflora was not published until 1812. The exact
date for Coreopsis diversifolia Jacq. I do not know. The page num-
ber and plate number would seem clearly to indicate a date later
than 1811. At all events, the existence of a B. diversifolia Willd.

Botanical Garden; drawing made in 1812. Stem purplish at base in illustration.

Asa Gray (Proc. Amer. Acad. 19: 16. 1883) to Bidens Dondiaefolia
Less. It matches the type of B. chiapensis very precisely. A dis-
tinguishing character of the species is the large number (12-20) of
narrowly linear exterior involucral bracts.

versally by other botanists. Klatt described B. guatemalensis from

THE GENUS BIDENS 537
Type specimen: Collected by C. Hoist, No. 76, in sunny places
of the higher mountains, mountain steppe, Usambara, German East
Africa, October, 1891 (Berl.).
Distribution: District of Usambara, German East Africa.
Specimens examined: Karl Braun 2820, Kingo-Kwai, western
Usambara, August 21, 1909 (Berl) ; idem 2857, eodem loco et tempore
(Berl.) ; Hoist 76 (type, Berl.) ; Albrecht Zimmermann 1776, Hermanns-
platte, western Usambara, February, 1908 (Berl.).
Hoffmann's type in Berlin consists of three flowering specimens
mounted upon one sheet. They lack mature or even submature
achenes. At first they were determined by him as Coreopsis Grantii
Oliv. (Bidens Grantii Sherff), but later he crossed out this determi-
nation and substituted the new name C, Holstii. His description of
the achenes ("Achaeniis juvenilibus alatis") was of necessity drawn
from the unripened ovaries. The winged character assigned by him
to the young achenes is not manifest on my examination of them.
They naturally are thin and delicate toward the edges, but this is
true of the achenes of many typical Bidens species when equally
young. Fortunately there since have been collected by Braun and by
Zimmerman additional specimens from the type district, Usambara.
These match the type very closely, and two excel it in having mature
achenes. The achenes are linear, unwinged, 3-6 mm. long, flattened,
antrorsely setose upon the margins and at the apex, exaristate or with
two setae very slightly larger than the rest and representing minute
aristae. Hoffmann described the aristae as very short ("aristis 2
brevissimis"), but, as may be seen from my plate, fig. g, the ovarian
aristae of his type, when compared with the body of the ovary, are
not very short. The species bears a strong habital resemblance to
Bidens Grantii (Oliv.) Sherff and in lesser degree to Coreopsis pin-
natipartita 0. Hoffm. From the latter it differs in its setose, exalate
achenes. From B. Grantii it appears to differ mainly in having the
achenes exaristate or only shortly aristate (a character here of some-
what uncertain value) and in the nature of its pubescence.

As already stated (Sherff, loc. cit.), the two type specimens are
extant in fairly good condition. Their several mature achenes are
seen on close inspection to be devoid of true wings (cf. Peters, loc.
cit., "achaeniis oblongis subcompressis marginatis sed vix alatis"),
and to have merely rough, thickened margins, similar to those on
certain species of true Bidens, e.g., B. aristosa (Michx.) Britt. In a
previous paper (Bot. Gaz. 59: 305-308. 1915) I have stated the
reasons for regarding such plants as belonging to Bidens.
Coreopsis Mattfeldii Sherff (Bot. Gaz. 76: 83. 1923) bears a strong
superficial resemblance to Bidens Steppia, but can easily be dis-
tinguished by its achenes and involucral bracts. The many mature
achenes on the type of C. Mattfeldii differ remarkably from the
ones on the type and other specimens (already cited) of B. Steppia.
For B. Steppia they are (at most) widely oblong-linear in outline,
7.5-9 mm. long and 2.5-3 mm. wide; there is merely a thickened
lateral ridge, wings being absent. For C. Mattfeldii the achenes are
much thinner and wider, the outer obovate, 6-8 mm. long and
4.25-5 mm. wide, the inner oblanceolate, about 8 mm. long and 4
mm. wide; all are winged, and even on submature fruiting heads the
rounded upper ends of the wings, adjacent to the aristae, are easily
visible. The external bracts about equal the inner ones in C. Matt-
feldii; in B. Steppia they tend to exceed the inner ones by at least
2-6 mm.

are described as odorless. The fruiting heads approach, in their
small size, those of B. kivuensis, but the general foliage habit and
habit of flowering heads are more as in B. Steppia.

Specimens examined: John Gossweiler 8936, alt. 1,300 meters,
vicinity of River Gola Luije, Malange, June, 1925 (Kew) ; Welwitsch

The type has the general habit of£. Steppia proper but differs
in the small, slender achenes. The existence of the var. leptocarpa,
as also of several transitional forms between B. Steppia proper and
var. leptocarpa, shows, in my opinion, that the achenial distinctions
for the ambacensis type are varietal rather than specific.

Type specimen: Collected by John Gossweiler, No. 4176, among
the ferruginous rocks near the fort at Kabango, Principality of
Amelia, Angola, Portuguese West Africa, December, 1907 (Brit.).
Distribution: From eastern Southern Rhodesia to Angola.
Specimens examined: Ex Dept. Agriculture, No. 2482, Salisbury,
Southern Rhodesia (Kew); Mrs. 0. Craster 211, eodem loco, com-
munic. May 27, 1914 (Kew); Gossweiler 4176 (type, Brit.).
At the time of writing the original description of Bidens rufo-
venosa, there were at hand only my large photograph of the type
and a small fragment which had been lent me. The one leaf on this
fragment had the pubescence along the veins of the lower leaf -sur-
faces conspicuously red-tomentose. The habitat cited by Goss-
weiler, "amongst ferruginous rocks," led at once to the thought that
iron in some form had been taken from the soil into the roots, then
carried through the stem and leaves to the lower leaf surfaces and
deposited there, doubtless as an oxide of iron. This view having
been rejected by an eminent plant physiologist to whom it had
been stated, the leaf was given for study to Dr. Sophia H. Eckerson,
then of the University of Chicago. She reported the color of the
pubescence as due to a red stain produced in the mucilage cells
along the veins. Apparently, then, the stain afforded a character of
diagnostic value.
More recently I have reexamined the type. Only certain leaves
possessed the rufo-tomentose character. Furthermore, the thickish
root was covered with a deposit, of the reddish color noted in the hairs
on some of the lower leaf -surfaces, but other material examined lacks
the red. Clearly the rufo-tomentose character is here a fickle one,
doubtless being entirely dependent upon the "ferruginous" nature
of the rocks or soil in the habitat.

Distribution: Known only from southeasternmost portion of
Belgian Congo.

In the herbarium at Brussels are two sheets labeled J. Bequaert
389. One bears a specimen having fairly large flowering heads
(2.5-4 cm. wide) with red or violaceous ligules and moderately thick,
not elongated achenes. This sheet bears Bequaert's original field
label and clearly is the one kept mainly in mind by De Wildeman
when he named and described Bidens rubra. It is, moreover, the
main basis of my description. The other sheet bears a very different
plant with small (7-8 mm. wide), discoid flowering heads and slender,
elongated achenes. This second specimen matches the type of
Bidens ciliata De Wild. (=B. paupercula Sherff), i.e., Bequaert 302,
and doubtless was really a duplicate of the B. ciliata type, but
through some error in mounting was given the wrong number. It
550 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
was unfortunately confused by De Wildeman with his B. rubra, as is
shown by his erroneously describing the achenes of B. rubra as
elongate, up to about 15 mm. long.

Type specimen: Collected by T. Kassner, No. 2725, under trees,
Mt. Kundelungu, Belgian Congo, May 10, 1908 (Berl.).
Distribution: Belgian Congo.
Specimens examined: Kassner 2725 (type, Berl.); F. G. Overlaet,
Kafakumba, April, 1925 (Berl.; Field, 3 sheets; Kew).
Appears closest in foliage and general habit to B. urceolata
De Wild., a species also collected by Kassner (No. 2710) on Mt.
552 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
Kundelungu.1 B. leptolepis has smaller flowering heads, very dark
red or dark purple, not light violet ligules, much more slender and
elongate external involucral bracts, ordinary (not conspicuously
margined above) internal involucral bracts, and lacks a definitely
urceolate shape to the tubular florets.
It was described originally from the single type specimen by
Kassner. Shortly afterward I was able to enlist the friendly co-
operation of Mr. F. G. Overlaet of Belgium. In April, 1925, Mr.
Overlaet's official duties had taken him to Kafakumba, Belgian
Congo, where he collected several handsome specimens of this
Bidens. These, together with various other Congo specimens found
by him, were forwarded to me and are now deposited in the herbaria
cited. They afford a much broader and more representative notion
of the species than was possible from the lone type specimen. The
achenes are mature, the leaves are mostly more divided, with shorter
and broader segments, and the external involucral bracts are often
more numerous than in the type and also often shorter and less
noticeably narrowed. The rays of the two dozen or more flowering
heads examined vary from dark red to densely dark purplish-red, as
in the type. With the aid of these additional specimens the above
amplified description has been drawn.

Specimens examined: Hildebrandt 2432a (type, Berl.).
Hildebrandt's No. 2432 was collected in quantity and proved to
be new (Bidens Hildebrandtii). Specimens were distributed to
several herbaria. His 2432a, though collected at the same time and
place, seems to have been rare, for apparently only a single specimen
was found, and that none too ample. The habit seems nearest that
of Bidens Fischeri (0. Hoffm.) Sherff, of German East Africa. From
that it differs in being more nearly glabrous, in having the exterior
involucral bracts also the achenes much wider, etc.

The material originally given by Schultz Bipontinus the manu-
script name Bidens Buchingeri and later given the name B. Schimperi
var. pilosa was collected by Schimper at Gaha-Meda near Dschad-
scha, Abyssinia. The specimens examined by me in Schultz Bipon-
tinus' herbarium (Par.) are merely a somewhat pilose-leaved but
glabrous-stemmed form of B. Schimperi. We must therefore follow
the course of Oliver and Hiern (Oliver, Fl. Trop. Afr. 3: 394. 1877)
and treat these names as synonymous.
Many species of Bidens are polymorphic as to foliage, and yet
reasonably constant as to characters of flower and fruit, but B.
Schimperi offers an amazing range of variation in all respects. Thus,
in typical B. Schimperi the external bracts of the involucre become
10-17 mm. long, but in forms of the species (of which B. acutiloba
Sherff must be considered one) these may become only 3-6 mm.
long. Again, in typical material, the achenial bodies range in length
from 0.9-2.2 cm., while in various forms these range as low as 3-6 mm.
long. Oliver and Hiern, also Otto Hoffmann, in their work on the
African flora came to recognize a large number of these forms as
merely variations of B. Schimperi, although to a novice these would
seem separate species.
Bidens prolixa S. L. Moore was founded upon C. F. M. Swynnerton
1884, northern Melsetter at alt. 60-180 meters, Rhodesia, April, 1907
(Brit.). Moore (loc. cit.) distinguished this plant from B. Schimperi
by "its slender habit with long stalked heads, its smaller leaves with
narrower lobes, its smaller heads, shorter involucres and narrower
ligules." Upon comparison with a considerable number of specimens
of B. Schimperi, B. prolixa is found to be connected much too closely
for specific separation.
B. punctata Sherff (PL CXLII, figs, i-q) was founded upon two
sheets of material (Kew) consisting of small plants with leaves
tripartite or even entire, not bi- or tripinnate as in ordinary B.
Schimperi. Their outer involucral bracts were noticeably shorter
than the inner ones. The fruiting characters were very similar to
558 FIELD MUSEUM OF NATURAL HISTORY— BOTANY, VOL. XVI
those of B. prolixa, and I therefore came later to regard B. punctata
and with it the less extreme B. prolixa as representing a variety (var.
punctata) of B. Schimperi. The diagnostic characters are found,
however, to be so uncorrelated and so prone to appear in different
combinations, that it seems difficult to justify maintenance of even
varietal rank for the prolixa or punctata forms.

The type had been determined at Berlin as a form of Bidens
lineariloba Oliv. That species is a very different plant, having the
exterior involucral bracts 9-13, linear-lanceolate or even narrowly
linear, strongly attenuate above, finally more or less reflexed, 6-11
mm. long; also anomalous inner paleae, which are widely elliptic or
obovate or truncate, the apex conspicuously and to a great length
linearly elongated, surpassing the spreading-awned achenes. The
habit is that of Bidens Kirkii (Oliv. & Hiern) Sherff, but the fewer

by zoologists, rather than from the Greek.

heads of B. Hoffmannii, the shorter, more often lobed and less par-
allel-sided leaf divisions, and the retrorsely barbed awns of the longer
achenes distinguish it easily from B. Kirkii. The species was named
in honor of Dr. Otto Hoffmann, who not only studied this and other
material collected by Volkens, but during his lifetime1 contributed in
a most important way to knowledge of the African species of Bidens.

8470, Dar-es-Salaam, September, 1894 (Berl.).
The two sheets of material (Stuhlmann 6403 and 7584) cited by
Otto Hoffmann for his var. gracilior differ from his species proper
(Coreopsis exaristata 0. Hoffm. = Bidens microcarpa Sherff) in having
the leaves less glandular-pubescent or sometimes even glabrate, their
divisions finer and much more acute or even acuminate, the involucre
less pubescent and the achenes not only 3-4 mm. long with all
except the innermost ones oblanceolate, but rather 4.5-6 mm.
long and all linear. The important achenial differences seem to have
been overlooked by Hoffmann.1 A specimen collected later by
Holtz (No. 406, Dar-es-Salaam, German East Africa, December 6,
1901) in the immediate vicinity of the type locality, Usaramo,2
agrees fairly well with the type as to foliage and involucre, and has
likewise longer achenes. These important characters of foliage and
achenes appear to entitle Hoffmann's variety to separate specific rank.

German East Africa, April 20, 1904 (Berl.).
1 Many mature achenes on the type, Stuhlmann 6403, have 1 or 2 minute
aristae (0.2-0.3 mm. long) and several have these aristae retrorsely barbed with
1 or 2 barbs. Had Hoffmann noticed this character he certainly would have
remarked upon it, probably even referring his specimen not to Coreopsis but
to Bidens, since with him the retrorse-barb character was considered diagnostic
of the genus Bidens (cf. Sherff, Bot. Gaz. 59: 305-308. 1915).
2 Spelled also Uzaramo (Century Atlas, 1899).

From most African species of Bidens this is easily distinguished
by its minute achenes. The absence of wings as well as of any other
distinctly Coreopsoid character made the transfer to Bidens seem
advisable.
The habitat is in the tropical forest up to 1,600 meters or more in
the mountains, ploughed-up areas in the virgin forest, low bush,
edges of plantings, etc.

In 1908, T. Kassner spent at least several weeks among and
around the Kundelungu Mountains, southwest of Lake Moero, in
southeastern Belgian Congo. Among his plants received at the
Botanical Garden of Berlin were no fewer than four new species of
Bidens and Coreopsis.1 Besides these he collected (Kassner 2710)
the violet-rayed Bidens urceolata DeWild., described previously
(Ann. Mus. Congo, Bot. IV. 1: 167. 1903) from a specimen (No. 464)
obtained in 1900 by Verdick at Lukafu, a locality in this same
region; also (Kassner 2859a) the red-rayed Bidens rubra DeWild.,
described more recently (Repert. Sp. Nov. 13: 203. 1914) from
specimens (J. Bequaert 389, Homble 563) obtained at Welgelegen.
DeWildeman (Ann. Mus. Congo IV. 2: 169. 1913) has referred this
plant to Bidens Kirkii (Oliv. & Hiern) Sherff (Coreopsis Kirkii
Oliv. & Hiern). A study of various specimens of Bidens Kirkii in
European herbaria, however, shows several pronounced distinctions.
Bidens Kirkii's rays are light yellow, not dark or brownish orange-
yellow; its exterior involucral bracts are mostly obtuse at the apex
and below the apex noticeably dilated ; its immature achenes are not
widest at the apex as in S. palustris, nor are they practically glabrous,
and their aristae are upwardly hispid, with numerous weak hairs,
not downwardly barbed with a few spinulose hooks; finally, B.
Kirkii does not appear from collectors' data to be a swamp-inhabiting
species as B. palustris was observed to be.

The two sheets examined are of material collected two months
apart. The first sheet has two plants, collected in May. One has a
sterile, leafy stem about 2.7 dm. tall; the other has a sterile stem
about 2.4 dm. tall and a fertile stem about 6.2 dm. tall, bearing three
fruiting heads. The leaves are of the more compound type and offer
a strong superficial resemblance to those of the North American
Coreopsis Delphinifolia Lam. The exterior involucral bracts are
equal to or a fourth or third shorter than the interior ones. The
achenes are the larger ones of the Latin description.
The second or type sheet bears material of a much better devel-
oped plant (or plants), collected in July. About two dozen heads
are present. The leaves are simple or laterally 2-lobed. The exterior
involucral bracts tend to greatly exceed the interior ones. The
achenes are the smaller ones of the Latin description.
As these differences appear to be of a seasonal nature, it seems
inadvisable to attempt any varietal distinction of one form from
the other.

Type specimen: Collected by W. E. Taylor, in the bed of a tor-
rent in a ravine at Rabai, Seyidie Province, British East Africa, Janu-
ary 5, 1886 (Brit.).
Distribution: Equatorial Africa from east to west coasts.
Specimens examined: John Gossweiler 3165, Cutchi River near
the fort, Cutchi, Angola, May 4, 1901 (Brit.); Taylor, in torrent bed
in a ravine, Rabai, etc. (type, Brit.).
Moore describes this species as "verisimiliter perennis." Goss-
weiler's label says "like perennial." While perhaps having a peren-
nial root, the plant has somewhat the aspect of an annual. Its tall
habit and smooth, very delicate, elongate, wiry branches, characters
especially well marked in Gossweiler's plant, are distinctive. The
heads look much like those of Bidens Kirkii (0. & H.) Sherff .
The remarkably discontinuous distribution displayed by B.
Taylori in its occurrence, so far as at present known, only at or near
the opposite coasts of Africa, led at first to my suspecting that the
species might prove to be only a form of some older and better known
species. It has been impossible, however, to find justification for
reducing B. Taylori to synonymy with any other species.

A species close to Bidens Elliotii, but having only about 8 ray
florets, the about 8 exterior involucral bracts only 5-7 mm. long and
scarcely equalling the interior, and the achenial aristae downwardly
barbed. In B. Elliotii the ray florets number mostly 10-14, the
usually 9-12 exterior bracts are more often 8-11 mm. long, and the
achenial aristae are erectly hispid. B. Phalangiphylla is close also to
B. Bequaertii DeWild., but has the much larger and more openly
dissected leaves,1 narrower exterior involucral bracts, and much
smaller fruiting heads with smaller achenes.

Easily distinguished from all other species of Bidens by the
numerous acute, finally spreading exterior involucral bracts and
the peculiar inner paleae, which are membranous-winged below and
with greatly extended, exalate apex running upwardly and surpass-
ing the bodies of the achenes. My description of the mature achenes
is drawn from the mature specimen, Braun 5372 (BerL), collected at
a spot (Lulangula) close to the type locality of Mininga. The achenes
simulate those of certain Hawaiian species in having the aristae
attached somewhat below rather than at the top of the achene body.

592 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
Otto Hoffmann, in his original determination of Baum's plant,
treated it as a new species. Whether he did so because at that time
he was unfamiliar with Bidens andongensis Hiern, or because, al-
though familiar with Hiern's species, he felt Baum's plant to be
distinct, I am unable to say. However, he later (Kunene-Sambesi
Exped. 420. 1903) referred the Baum specimen to B. andongensis
Hiern. Since the main differences lay in the size and shape of the
involucres, also the number and shape and proportionate size of the
exterior involucral bracts, one might indeed have suspected that
Baum had collected merely an atypic and less robust form of B.
andongensis. The various specimens sent in more recently by Goss-
weiler to the British Museum of Natural History show similar
peculiarities as to these characters, thus strengthening the belief
that we have to do with a distinct species.
The species was named in honor of the late Spencer L. Moore of the
British Museum of Natural History, who had done much admirable
work upon the African species of Bidens, and who, independently,
had interpreted the Gossweiler plants as typifying a new species.

April, 1906 (Brit.).
Distribution: Angola.
Specimens examined : Gossweiler 3021 (type, Brit.).
A form so peculiar in fruit characters that it is perhaps best
treated for the present as a variety. Various considerations indicate
no basis for regarding it as a separate species. The achenes are
minutely warty and 5-8-aristate (commonly with 3 long aristae and
2-5 short ones, with frequently 4-10 additional rudimentary, smooth,
sharp aristae completing a crown). The variety is seen to be com-
parable, in its relation to the species proper, with the var. verrucifera
Moore of Bidens crocea Welw. In its large number of aristae it makes
a singular approach to Ericentrodea mirabilis (Sherff) Blake & Sherff,
a plant that differs widely in other respects.

Type specimen: Collected by Friedrich Welwitsch, No. 3529, in
sandy, bushy places at altitude of 720 to 1,140 meters, near Quibinde
(Quibinda), not far from the Cuije River, District of Pungo Andongo

In an earlier article (Bot. Gaz. 59: 312. 1915) I have stated that
Gossweiler's 3631 may properly be taken as representative of this
species. In many respects both Gossweiler's plant and Hiern's type
material appear to be too close to Bidens Buchneri (Klatt) Sherff, a

species likewise from Angola. The latter species, however, has the
achenial aristae only sparsely barbed and the few barbs near the base
are erect, not retrorse; furthermore, the rays (15-18) are more numer-
ous than in B. andongensis and none of the leaves, so far as I know,
are ever as narrowly petiolate as in some cases with B. andongensis.

THE GENUS BIDENS 595
Klatt (loc. cit.) described the achenial aristae as glabrous, but a
study of ten immature achenes removed from the one large flowering
head on the type sheet shows all the aristae to be downwardly barbed
near the apex and upwardly barbed near the base. The inner bracts
of the involucre, which are shorter than the outer, the more numer-
ous rays, and the peculiarly barbed aristae appear to distinguish this
species sufficiently from B. andongensis Hiern.
We may note that in a second publication (Ann. Naturh. Hofmus.
Wien 7: 103. 1892) Klatt repeated his description of this species
with only slight changes but cited Von Mechow's No. 394 instead
of the Buchner plant. However, Von Mechow 394 does not repre-
sent B. Buchneri and must be discarded.1

There are two ample specimens of the type. Their achenes are
wingless and the aristae lack barbs. A specimen from Uganda
(Dawe 415) has, however, many of the aristae retrorsely barbed at
the apex. This last specimen I had described in manuscript as a
new species, but later found it specifically identical with the type
specimens of Coreopsis Seretii. It may be remarked that, had De-
Wildeman relied upon the more significant presence or absence of
achenial wings instead of the presence or absence of retrorse aristal
barbs (cf. Sherff, Bot. Gaz. 59: 308. 1915), he would have had no
hesitation in placing the species in Bidens at the outset.

the type of B. Buchneri (Buchner 31) it does, indeed, offer a strong
resemblance. In fact, I have suspected that through further such
forms as Von Mechow 394, B. grandis may be proved to pass into
B. Buchneri and perhaps even be shown to be conspecific. Certain it
is that distinction is impossible in some cases except upon the ques-
tionable basis of upwardly (B. grandis) versus downwardly (B.
Buchneri) barbed aristae.1 For the present it seems wise to await
more positive data before attempting to merge the two.

The type of Bidens rmvenzoriensis (Moore) Sherff, G. F. S. Elliot
7410, was stated by Moore to have been collected at Mt. Ruwenzori,
but the original field tag on the cotype at Kew gives, as the type
locality, Kavirondo, some 400 kilometers to the east.1 Both the
type and the cotype consisted merely of fragments from the inflores-
cence. Thus the original description was necessarily very faulty
and misleading as to general habit, size of leaves, etc. Fortunately,
there have been received at Kew several additional specimens from
1 The name ruwenzoriensis was not entirely inappropriate, since Mt. Ruwenzori
was Elliot's destination, and his herbarium labels bear the heading, "Ruwenzori
Expedition."

the same general region, which show the species to be a tall, hand-
some perennial, doubtless reaching a height of 2 meters, although
Small reported it as growing 2-3 feet. As the mutual identity of
all these specimens admits of no doubt, I have taken advantage of
them to draw up a fresh and amplified description of the species.
The type proper of B. coriacea consists of seven fragments from
the inflorescence, which offer at least a superficial resemblance to the
type of B. ruwenzoriensis. Indeed, Moore (loc. cit.) appears to have
suspected them of being the same. In the B. coriacea type the outer-
most involucral bracts, as noted by Moore, are not noticeably longer
than the inner ones, and the achenes are mainly triaristate. In the
type material of B. ruwenzoriensis, also in the material by Diimmer,by
Small, by Snowden, and by Whyte, the outermost bracts are easily
the longest and the achenes are biaristate. In a former article (Bot.
Gaz. 81 : 52. 1926) I pointed out the similarity between the two forms.
Since then I have studied the material by Sir Evan James, which has
the achenes biaristate as in the type of B. ruwenzoriensis, but the
outermost bracts not much longer than the others. With this
connecting form at hand, there appears no justification for attempt-
ing further retention of B. ruwenzoriensis as a separate species.

Native name said to be "maharrama." The foliage strongly
suggests in outline that of some species of Crataegus. Hoffmann (loc.
cit.) described the ovaries as winged, but a careful search through his
type material shows that he used the term carelessly, for there is
no trace of definite wings such as are usually found in true Coreopsis.

Their absence on the many submature achenes examined makes it
appear preferable to class the species with Bidens.

The branches as preserved in herbaria have the appearance of
having come from a large, coarse herb. Uhlig, however, labeled
his No. 414 a shrub ("Strauch d. Strauchregion") and Volkens, in
labeling his own No. 537, likewise described it as a shrub ("Strauch
bis 2 m. hoch"). The other collectors are silent upon this point.
Hoffmann's description (loc. cit.) of the species as a shrub doubtless
was based upon Volkens' label. It is doubtful, however, if the plants
form true woody shrubs (frutices) in the common sense of the term.
The discontinuous distribution shown by the occurrence of this
species in Angola as well as in British and German East Africa is
notable. The Angola plant (Gossweiler 3640) was carefully compared
with Kassner 870 from British East Africa and found to match well.

The type is in the Schultz Bipontinus Herbarium at Paris. By
Schultz Bip. ithad been given the nameCoreopsis Buchingeri, which has
appeared occasionally in literature but without description. The
closest ally is Bidens Rueppellii. B. rotata appears to differ, however,
in having more nearly glabrous stems, different foliage, larger involu-

cral bracts, and larger achenes. The slender rays, regularly 12, offer
a fanciful resemblance to the spokes of a wheel, whence the trivial
name. The interior involucral bracts have many of the lower
median hairs of the dorsal surface expanded below into flat scales, as
occurs sometimes in B. chaetodonta and commonly in B. Rueppellii.

Oliver and Hiern (Oliver, Fl. Trop. Afr. 3: 389. 1877) were
inclined to regard this as a distinct species, as indeed Vatke had
earlier suspected it of being. Oliver and Hiern noted that it had
"the technical characters of Wedelia; the general appearance of the
plant is however quite that of Coreopsis." The plant matches Bidens
in its achenes somewhat better than Coreopsis.

1 The type sheet in Schultz Bipontinus' herbarium at Paris has a small plant
at the right, with one fruiting and two flowering heads. This has the Ruppell
label underneath. At the left is a small fragment from a larger but specifically
identical plant, with one fruiting head and the several leaves more compound and
more noticeably setigerous-toothed. As no additional field data are given under
this second specimen, it may well be that the two belonged to the same collection.

THE GENUS BIDENS 629
Type specimen : Cultivated in garden of J. Veitch and Sons, 1908,
from material collected by Captain Diespecker in British East Africa
(Kew, 2 sheets).
Distribution: British East Africa.
Specimens examined: Hort. Veitchii et filiorum (Kew, 2 type
sheets).
The first type sheet has the six flowering heads measuring about
2.2-2.7 cm. across, with about 12-16 exterior bracts. The second
type sheet has likewise six flowering heads, but these are mostly
4-4.5 cm. across and the exterior bracts number 16-22. These
differences are construed as representing different states of luxuri-
ance due to conditions of cultivation.

Type specimen: Collected by Wilhelm Schimper, No. 766, at
margins of groves in valleys near Adoa, Abyssinia, November 12,
1838 (Par., 2 sheets).1
Distribution: Abyssinia and perhaps Eritrea.
Specimens examined : Schimper 766 (2 type sheets).2
The achenes of this variety lack aristae but have the pappus
more or less definitely coroniform or cup-shaped (whence the
name Microlecane given by Schultz Bipontinus). Tegetmeyer (0.
Hoffm. loc. cit.) has illustrated this peculiar pappus in its extreme
development.
In his original treatment Schultz Bipontinus referred this form,
as representing a subgenus, to Chrysanthellum. The affinity with
1 The two type sheets of Chrysanthellum abyssinicum at Paris both bear the
number 578. A printed distribution label also is present on the first type sheet
and this has the number 766 in print with the citation "Fl. Ratisb. Anni. 1842
pag. 440, ubi per errorem plantae numerus 578 tribuitur." In his original
description Schultz Bipontinus gave Schimper's number as "it. abyss. Sect. II. no.
578," but later, in Walpers' Repertorium, he gave it as "1078." Just why these
discrepancies arose is not clear, but there can be no question as to the authenticity
and identity of the type material.
2 See footnote (p. 628, no. 2) under species proper.
630 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XVI
that genus seems purely fallacious. Bentham and Hooker (loc.
cit.) elevated the subgenus, which Schultz* Bipontinus had named
Microlecane, to the rank of a genus separate from Chrysanthellum.
However, through Bidens setigera and B. setigeroides the type mate-
rial of Microlecane is too closely allied with Bidens to justify generic
segregation. Thus, for example, B. setigera has very long, slender
aristae and many of the achenes are much the same as in other
species of Bidens (sect. Steppia); but a fair percentage of them
have the shorter or secondary pappus noticeably modified into an
annular or cupuliform corona (not shown in my illustration), thus
strongly suggesting the so-called Microlecane material, here treated
as the var. abyssinica. All things considered, it seems that the var.
abyssinica bears somewhat (though not entirely) the same relation-
ship to B. setigera proper that Bidens aristosa var. mutica bears to
the species B. aristosa proper.

Distribution: Known only from type locality in German East
Africa.
Specimens examined: Busse 2257 (type, Berl.).
The branches of the type material have internodes 1-1.5 dm.
long. Busse's label lists the plant as an herb and gives its height as
being up to 2 meters. The interior involucral bracts (like those of
Bidens praecox) are connate below, often even up to the middle, thus
simulating those of the allied genus Thelesperma, although the gen-
eral habit in no way suggests Thelesperma. The achenes are thick-
margined and suggest those of some species of Coreopsis, but the
occasional retrorse barbs are foreign to that genus.

Type specimen: Collected by Walter Busse, No. 2523, in sandy
soil, sunny places in legume forest, Mayanga, District of Lindi,

Africa.
Specimens examined : Busse 2523 (type, Berl.).
Florets, both ray and disc, are lacking on the type. The achenes
had been well formed even on small, young heads, differing in this
respect from those in ordinary species of Bidens. Moreover, the
achenes had produced at the apex some sort of secondary growth,
this imparting a more or less capitate appearance. The growth in
question is mostly 0.5-0.8 as wide as the maximum width of the
achenial body and is variously truncate or protuberant, ovoid
or subglobose, sometimes appearing faintly as if representing a rem-
nant of the disc floret. The general habit is that of many annual
species of Bidens (unless as to the submedianly connate interior
involucral bracts, which, however, are matched by those in B.
phelloptera) , to which genus the species is apparently best referred
for the present.

2 Bidens carnea Heer is the customary citation, but an early and apparently
original specimen by Regel (Berl.) is accompanied with the inscription "Bidens
carnea Heer et Rgl."
3Baillon, cited by the Index Kewensis, really gave (Hist. PI. 8: 305. 1886)
the name Dahlia Cervantesii Lag. (cf. DC. Prodr. 5: 494. 1836). While he treated
Dahlia as a section of Bidens (op. cit. 221, footnote 8; 305, footnote 8), he really
did not directly make a new combination.
4 So also B. coccinea (Cav.) Gomez (Anal. Hist. Nat. Madr. 19: 275. 1890).

1 DeCandolle (loc. cit.), the Index Kewensis (4: 1180. 1895), A. H. Moore
(loc. cit.), and various other authorities give Lessing for the combination Verbesina
crocata, but Lessing (Syn. Gen. Comp. 232. 1832) did not make a definite or
decisive transfer from Bidens to Verbesina. Nor should we overlook the fact that
in his index (op. cit. 445) Lessing retained Bidens crocata Cav. but entirely omitted
(op. cit. 472) mention of any Verbesina crocata.
2 Fide Ind. Kew. 1: 300. 1895. The type of B. denudata Turcz. was collected
by Cuming (No. 1375) in the Province of Cagagan, Luzon, Philippine Isls. I do
not recall having seen it.
3 Desfontaines gave merely a name for his plant and indicated it to be a
perennial. DeCandolle (Prodr. 5: 597. 1836) presented a description, citing
plants from Brazil by Commerson and by Lund. Lund's one plant (Del.) studied
is true B. pilosa L. The Prodromus Herbarium (Del.) appears to have no speci-
mens by Commerson. All told, the Prodromus specimens of "B. dichotoma Desf."
are five in number, four being true B. pilosa L. and one being B. pilosa var. minor
(Bl.) Sherff (cf. Chodat, Bull. Herb. Boiss. 2. 2: 394. 1902).
Desfontaines later published (Cat. PI. Hort. Reg. Paris ed. 3. 185.
1829) "Bidens dichotoma H. p." as a synonym for Blainvillea rhomboidea Cass.
Diet. Nat. Sci. 29: 494. 1823. (Cf. O. E. Schulz, Bot. Jahrb. 50, Suppl. 182.
1914). A small but fine specimen of a "Bidens dichotoma" is preserved (Petrop.)
from material cultivated in 1815. Riedel sent it (whether the seed or the plant
itself the label does not specify). It is a Blainvillea and may well have come
from the material on which Desfontaines founded his reduction of B. dichotoma
to synonymy in 1829.

being nearest B. parviflora Willd., wherefore Forbes and Hemsley
(Journ. Linn. Soc. 23: 435. 1888) stated that it might be referable
to B. parviflora or to B. bipinnata. The plant, however, is typical
Glossogyne tenuifolia Cass., and the species has already been thus
equated on a label for another specimen (legit Hillebrand) by some-
one in the Berlin Herbarium (cf. Sherff, Bot. Gaz. 76: 91. 1923).

this species.1 In my earlier studies it seemed that the specimens of
this handsome species of the Nyassa region were of two kinds,
differing generically on the basis of the winged character of the
achenes. Further specimens have shown that some material is
merely more tardy than the rest in displaying achenial wings. As
the specimens mature, their achenes become fairly well winged. Be-
sides the type (W. Goetze 731, on red laterite, hilly plateau, in thin
bush growth, at altitude of 1,700 meters, Bweni, Uhehe, March 11,
1899; BerL), I have seen the following: Ad. Stolz 764 pro parte,

Bidens Palmeri Gray, Proc. Amer. Acad. 22: 429. 1887. = Cosmos
Landii Sherff, Bot. Gaz. 64: 29. 1917. This species, with its strongly
ribbed leaves, is very close to Cosmos Crithmifolius H.B.K., but
differs in its yellow rays and slightly dissimilar leaf outline. In most
specimens the achenes are clearly erostrate, but occasionally some of
the central ones become highly elongated above, appearing almost
distinctly rostrate and thus exactly simulating those of such species
as Cosmos Crithmifolius and C. linearifolius. This is especially
notable in certain material collected by Barnes and Land (Nos. 164
and 189, Field). In fact, the subrostrate character of the achenes
was known to Gray (cf. Gray, loc. cit., "achaeniis subulatis . . .
subrostratis"). Yet, curiously enough, he placed this species in
Bidens, while previously (Proc. Amer. Acad. 19: 16. 1883) he had
determined as Cosmos Seemannii a Ghiesbreght plant, described
by himself as having "essentially beakless . . . achenes." I have
examined the following specimens: Edward Palmer 315, Rio Blanco,

138. 1874; cf. Sherff, Bot. Gaz. 76: 80. pi. 8. 1923. Schultz Biponti-
nus, who reduced Heterosperma to Bidens, published without
description the name Bidens ( Heterosperma) rhombifolia for a plant
collected by W. Lechler, No. 1576, in rubbish-covered places, May,
1854, Tacna, Peru. Later Grisebach (loc. cit.) transferred the species
to Heterosperma, supplying a very scant description: "Species parum
ab H. maritimo Kth. foliis latioribus (2" longis, 1" latis) recedens."
The leaves of H. maritimum were described as 4-4.5 lines wide;
those of H. rhombifolium are 7-9.3 lines wide, and because of this
greater width have a remarkably different aspect. The achenes of
the outer, perfect (hermaphrodite) florets in H. maritimum were
described as obsoletely tridentate at the apex, but the corresponding
achenes of H. rhombifolium are definitely biaristate.2 In 1914, on
1B. purpurea Downing (Nat. Great L. Region 317. 1922) is an error for Bra-
senia purpurea Casp. (=B. Schreberi Gmel.).
2 It should be remarked, however, that in the type plate, fig. 3, of H. maritimum,
two definite aristae are shown on the achene. No tridentate character is indicated.
THE GENUS BIDENS 643
finding one of Lechler's original specimens in Paris, I made a draw-
ing of it (Sherff, Bot. Gaz. 76: 80, pi. 8. 1923). The leaves suggested
strongly the possibility of the plant's being the Heterosperma
ovatifolium of Cavanilles, described from "Peru" in 1822 (Cav. Descr.
204. 1802), and later renamed H. ovatum by Willdenow (Sp. PL
ed. 4. 3: 2129. 1804). 1 Cavanilles' description of the leaves, however,
"Las hojas son aovadas, de cinco a ocho lineas de largo," shows his
plant to have been one of the smaller-leaved species native to
that region. In the Paris specimen of H. rhombifolium the principal
leaves all measure from 9 to 16 lines long,2 not 5-8 lines as given by
Cavanilles. The plant, on comparison with Kunth's plate in Hum-
boldt and Bonpland's Nova Genera et Species Plantarum (4: pi.
383. 1820), appears to differ from H. maritimum mainly in having
large, rhombic-ovate instead of small, rhombic-lanceolate leaves.
Since the paucity of material in the larger herbaria makes it
impossible actually to settle the separate identity of H. rhombifolium
as distinct from H. maritimum, attempts at synonymizing the two
would seem for the present to be valueless.

1 In Cavanilles' description, the name "Heterosperma ovatifolia" [sic] appears
not as a binomial but merely as the first two words of a short Latin description,
followed by a longer Spanish description. Cavanilles' method of presenting his
plant names in his Descripciones is not the orthodox post-Linnean one, and only
by examination of his treatment of the many other plant names does one find
surely that the first two words in each description are the intended binomial.
2 Grisebach's measurements, "2* longis, 1* latis," appear to have been care-
lessly taken.

(cf. Sherff, Bot. Gaz. 61: 497, footnote 2. 1916). Heterosperma is
very closely connected with Bidens through Heterosperma Xantii
Gray, the type of which (Gray) is matched by that of Bidens Xanti-
ana Rose (U.S.); a species best retained in Heterosperma, a view in
accord with the treatment by Brandegee (Zoe 1: 309. 1890), who,
moreover, has since positively corroborated (in lit., 1913) my
equation of Bidens Xantiana Rose with Heterosperma Xantii Gray.
ADDENDA
71. Bidens segetum Mart, ex Colla, p. 194, PI. XLIX and PI. L.
Colla's rare work (Herb. Pedem.) describing this species is inacces-
sible to me. Drs. Henry A. Gleason and Elmer D. Merrill very
kindly sent me copied portions of the text. From the inscription
("Bidens segetum Mar.") accompanying Colla's type specimen and
from Colla's citation of the herbarium of Martius ("14. B. segetum
= Mart. hb.") as seen in these copies, though set forth somewhat
unconventionally, it is evident that "Martius ex Colla" should be
given for the authorship of the name B. segetum. (Similarly, B.
fervida Hort. Erf. ex Colla is correct for the full citation of Colla's
B. fervida on p. 366.)

Type specimen : Collected by C. H. Mueller, No. 2267, abundant
in meadows above timber line, on the peak of Cerro Potosi, Galeana,
Nuevo Leon, Mexico, July 21, 1935 (Field).
Distribution: Known only from type locality in Nuevo Leon,
Mexico.
Specimens examined: Mueller 2267 (type, Field).
The type sheet bears seven specimens. The dried capitula offer
an illusory resemblance to those of most South American species of
Coreopsis, because of the conspicuous, dark interior involucral bracts.
I am indebted to Mr. Paul C. Standley of Field Museum for oppor-
tunity to study this recently collected material (which he had very
properly considered as representing a new species), and to prepare
a detailed description for insertion in this work. — The affinities are
probably closest with B. Anthemoides, B. andicola, and B. triplinervia
var. macrantha.

Type specimen : Collected by K. G. Lindblom, in Ukamba, British
East Africa, 1911-1912 (Stockh.).
Distribution : Known only from type locality in Ukamba, British
East Africa.
Specimens examined : K. G. Lindblom, Ukamba, 1911-1912 (type,
Stockh.).
The type was found, on the eve of publication, among a large
assortment of undetermined specimens received from Th. Arwidsson
of the Natural History Royal Museum of Stockholm. In my Clavis
it runs down to the second i on page 65. From the specimens there
given, however, it differs at once in one or more of the characters
noted : glabrous stem and leaves, corymbose-paniculate inflorescence,
capitula 3-4 cm. wide and about 12-13 mm. tall, exceptionally
elongate-filiform and retrorsely barbed aristae of the usually triaris-
tate ovaries, etc.
