largest, and slightly rhomboid. Racemes rather few-flowered ; the terminal
ones often panicled. Corolla bright purple and violet. Legumes about an
inch long.— Elliott and Dr. Darlington, on the authority of Muhlenberg, in*

stipules and legumes also different. Muhlenberg, in his unpublished Flora
Lancastriensis, remarks that he has H. humifusum both from New England
and Carolina ; but his description does not perfectly agree with the plant from
Massachusetts, which alone we have seen.

21. D. lineatum (DC.) : stem angled and finely striate, slightly pubescent;
leaves on short petioles ; leaflets (small) orbicular, nearly glabrous ; stipules
triangular-subulate, small, persistent ; flowers mostly in terminal elongated
loose panicles ; upper lip of the calyx 2-clefl, the middle segment of the
lower lip longest ; legumes (small) sessile, minutely hispid, of about 3 nearly
orbicular rather oblique joints.— DC. prodr. 2. p. 330 ; Hook. ! compan. to

Desmodium. LEGUMINOSjE. * 365

The species of this extremely difficult genua present such diversities, and often
appear to approach each other by such gradations, that it is by no means easy to
define them properly. The most constant characters may commonly be derived
from the form of the joints of the legume ; but these are frequently Blight and not
easy to be expressed in words. Having obtained additional materials and informa-
tion since our account of the earlier portion of this genus was published (Oct.
1838 ; to spec. no. 8. p. 360), we append a few notes on the subject.

The genus Ototropis, N. ah E. {delect, eem. hort. Vratisl. 1838, p. 3.) would
include many of our species, so far as the calyx is concerned, and several agree
with it in the form of the legumes ; but in this respect every gradation may be ob-
served, and other species which agree with Ototropis in fruit have a very different
calyx ; so that we see not how it can be adopted even as a section. It should have
been stated, perhaps, in the generic character of Desmodium, that the upper lip of
the calyx is often entire, and sometimes the calyx is nearly equally 4- or 5-toothed.
The joints of the pod are reticulated and more or less hispid with uncinate hairs in
all our species.

D. Canadense. DC. ! (Hedysarum Canadense, Linn. kort. Cliff. ! $ spec. .')
To the character should be added : Petioles very much shorter than the leaflets ;
stipules rather persistent ; legumes nearly sessile (much smaller than in D. canes,
cans), of about 5 roundish rather oblique joints.

0. longifoUum : leaflets lanceolate-ovate, membranaceous ; stipules lanceolate ;
racemes more lax. — D. longiiblium, Nutt.J mss. — Arkansas, Nuttall! Dr.
Pitcher ! — We have specimens intermediate between this and the ordinary form of
the species, collected in Illinois by Mr. Buckley. The petioles in D. Canadense
are ordinarily scarcely longer than the petiolule of the terminal leaflets ; but this
variety somewhat approaches D. canescens.

D. eanescens, DC. (ex syn. & descr.) Hedysarum canescens, Linn. hort.
Cliff. ! (1737) £ ex syn. Chronov. ! not of hort. Up*. ! (1748), which is a Jamaica
plant; excluding also the syn. H. triphyllum, olc. Sloane! and Onobrychis
Americana, floribus spicatis. 4c. Pluk. / which both relate to another West Indian
species. H. viridiflorum, Willd. ! Pursh ! $c. D. viridiflorum, DC. t <£c. — The
H. canescens, Willd. ! is the Linnean plant of the Hortus Upsalensis. Our plant
is accordingly, as we supposed, the original H. canescens, according to the speci-
men in the herbarium of the Hortus Cliffortianus, now belonging to the British Mu-
seum. The proper herbarium of Linnaeus contains the plant of the Hortus Upsa-
lensis only. It is the former which Linnaeus compares with H. Canadense (also
established in Hort. Cliff.) To distinguish it more perfectly from this as well as
the two species with which Linnaeus confounded it, we add the following
characters: Petioles about the length of the broadly ovate leaflets, which
are reticulated beneath, and scabrous on both sides, but especially beneath, with
long and stiff appressed hairs and a minute uncinate pubescence ; legume with a
short stipe.

0. viUosissimum : panicle and upper part of the stem very villous ; leaflets ob.
long-ovate ; upper lip of the calyx sometimes very deeply cleft. — D. Canadense,
var. Hook. 4t Am. eompan. to hot. mag. 1. p. 22. — St Louis, Missouri, Drunu
mondS

D. DUUnii, Darlingt. (D. Boottii, Torr. ! in Curtis, eat. Wilmingt.pl. Hedy-
sarum Marilandicum, Willd.!) — The joints of the legume were accidentally
described as oblong instead of rhomboid. It varies greatly in the size of the
leaves, which are sometimes obtuse at both ends, and sometimes acute.

D. viridiflorum y Beck. — Stem scabrous towards the summit ; stipules rather per.
sistent, — In specimens from Florida, recently received, with mature fruit, we find
the legumes somewhat even on the back ; the joints slightly convex on that side,
and much dilated and rounded below, so as to assume a rather semi-orbicular out-
line. The old leaves are less tomentose beneath. We have another form from
Louisiana (Dr. Hale) with ovate-oblong leaves, and the joints of the young le-
gumes somewhat rhomboids!. Possibly two or more species are confounded under



Hedysarum volubile, Linn, (founded on Dill. Elth. t. 143,/. 170.) is Galactia
pilosa or G. mollis.

366 LEGUMINOS&. Lespedeza.

44. LESPEDEZA. Micks. ft. 2. p. 70, t. 39 ^40.

Calyx with 2 persistent bracteoles at its base, deeply 5-cleft ; the segments
linear-lanceolate or subulate, nearly equal, the two upper ones sometimes
more or less united. Corolla inserted into the base of the calyx : vexillum
roundish or oblong, somewhat unguiculate, more or less appendiculate at the
base by the inflexed margins : wings nearly straight, as long as the keel,
often auriculate at the base on one side, and, as well as the very obtuse
slightly curved keel-petals, on slender claws. Stamens diadelphous (9 &
1) : anthers uniform. Style filiform : stigma capitate. Legume lenticular,
mostly flat, small, reticulated, unarmed, indehiscent, 1 -seeded.— Perennial
herbs or sufTrutescent plants, with pinnately trifoliolate reticulated leaves.
Stipules setaceous or subulate : stipelles none. Flowers in axillary pedun-
culate spikes or racemes, and often with other apetalous and imperfect but
fertile ones, mostly in subsessile glomerules. Bracts minute, 3 together, 1-
2-flowered.

§ 1. Flowers of two hinds, viz : perfect, although seldom maturing fruit ; and
fertile but mostly destitute of stamens and petals ; the latter either on the
same few-flowered peduncles, or in subsessile glomerules : calyx slightly bila-
biate, the 2 superior segments often united at the base : corolla violet and
purple, longer than the calyx: stems diffuse, procumbent, or erect.—
Eulespedeza.

The fruit, in this section, is chiefly produced by the apetalous flowers, which are
«mall and commonly escape notice until the legumes are formed. The style, in
these flowers, is short and Rooked, as in Amphicarp&a and other analogous cases ;
and by this character the two kinds of legumes may be distinguished. The ovary
U not naked, as in Stylosanthes, Chapmannia, and other genera of this tribe, but is
surrounded by a calyx, and the rudiments of petals and filaments may sometimes be
detected. A knowledge of this circumstance will render our species much better un-
erstood than formerly. Authors have sometimes described the calyx from the apeta-
lous flowers, where it is mostly smaller, which has caused some discrepancies. Little
reliance is to be placed upon the decree of union of the two upper segments of the
calyx : in L. repens and L. procumbens they are sometimes united almost to the tip,
and again distinct nearly to the base.

1. L. procumbens (Michx.) : tomentose-pubescent throughout except the
upper surface of the leaves, prostrate ; the branches assurgent ; leaflets oval
or elliptical, mostly retuse, the uppermost often obovate ; peduncles axillary,
simple, elongated, sometimes a little paniculate at the extremity of the
branches, few-flowered ; apetalous flowers occupying the lower peduncles,
and also often subsessile in the axils of the lower leaves ; legumes minutely
pubescent, nearly orbicular. — Michx. ! ft. 2. p. 70, L 39 ; Pursh I ft. 2. p.

Sandy soil, Massachusetts ! to Florida ! and Louisiana. Aug.-Sept—
Stems several from the same root, 2-3 feet long, very densely pubescent with
soft spreading hairs. Petioles of the lower leaves as long as the leaflets ;
those of the branches often very short. Corolla purple tinged with violet. Le-
gumes pubescent, about 1 J line in length and almost as wide as long*— We
Have never observed a 2-jointed legume in this species.

2. L. repent : prostrate or diffusely procumbent* minutely pubescent with
closely appressed hairs, or nearly glabrous ; leaflets oval or obovate-elliptica),
glabrous above, the uppermost emarginate or somewhat obcordate ; petioles
mostly very short ; peduncles axillary, filiform, simple, few-flowered ; the>
lower ones (sometimes short) bearing apetalous flowers ; legumes minutely
pubescent, nearly orbicular.— L. repens, Bart, prodr.Jl. Phuad. ? L. pros-

Dry sandy soil (Upper Canada, ex Hook.), New Jersey ! to Georgia !
west to Kentucky ! and Louisiana ! Aug-Sept.— Stems several from the
same root, often simple, very slender. Legumes as in the preceding species ;
from which it scarcely differs except in the kind and degree of the pubescence,
the rather smaller flowers, and more slender habit. The very short petiole*
are not wholly constant, and equally exist in some states of L. prooumbens.
— Hedysarum repens of Linnaeus was founded entirely upon the Virginian
plant, and not upon Dill. Eith. t. 142,/. 169 (a Ceylonese Desmodium), as
has been supposed ; for the reference to Dillenius only makes its appearance
in the second edition of the Species Plantarum, and Virginia is the only
habitat given : hence we have restored the original specific name.

3. L. violacea (Pers.) : stem erect or diffuse, pubescent, branching ; leaf-
lets varying from oval-oblong to linear, hairy or canescent with appresed pu-
bescence beneath, equalling or longer than the petiole ; racemes axillary r
few-flowered, sometimes shorter than the leaves, and sometimes in part ex-
serted on slender peduncles ; apetalous flowers glomerate and subsessile in
the axils of the leaves ; legumes minutely pubescent with short appressed
hairs, or nearly glabrous, ovate, much longer than the calyx.— Pers. syn. 2.
p. 318 ; Pursn ! I. c. Hedysarum violaceum, Linn. ! spec. 2. p. 749 (excL

m. -diver gens : peduncles toward the extremity of the branches filiform and
much longer than the leaves, the flowers rarely producing fruit ; leaflets oval
or oblong.— L. divergens, Pursh ! I. c. ; DC. t. c. Hedysarum divenrens-
WiUd.fLc.

0. sessiliflora : flowers somewhat glomerate on peduncles much shorter
than the leaves ; those at the base chiefly apetalous and fertile ; leaflets ob-
long or elliptical.— L. sessiliflora, Michx. I. c. (partly) ; Pursh I I. c. ; Nutt*

ceum, Linn. ! in part ; Willd. ! I. c. (Varies with the leaflets slightly pu-
bescent and almost tomentose beneath.)

y. angusUfolia : peduncles short ; the flowers glomerate toward the extremi-
ty of the branches ; petioles slender, mostly erect ; leaves much crowded above
and fascicled on short branchlets ; leaflets narrowly oblong or linear.— L.
reticulata, Pers. I. c ; NutL ! I. c. ; DC. ! I. c. ; DarUngt.1. c. L. sessili-
flora, partly, Michx.! L c L. angustifolia, Darlingt. I. c. ed. 1. L. fru-

junceum, Walt. Medicago Virginica, Linn. ! I. c. (pi. Gronov. !) (Varies
with the leaves somewhat hairy beneath to canescentJy tomentose.)

Borders of woods and thickets, Canada ! and Northern States ! to Florida f
and Louisiana! Aug.-Sept.— The Hedysarum violaceum of Linnsus in-
cludes both L. divergens and L. sessiliflora, and to the same species L.
reticulata must certainly be referred. In comparing the size of the legume
with the calyx, it should be remembered that the petaliferous flowers in this
species seldom perfect fruit, and that the calyx of the apetalous ones is
smaller. The narrow-leaved variety is perhaps always erect.

4. L. Sfavci (Nutt.) : stem nearly erect, branching, tomentose-pubescent ;
leaflets oval or roundish, pubescent or silky-tomentose, longer than the

Dry hills, Northern States, especially New Jersey ! to Louisiana ! Ark-

of forms^and is not easily defined. It is, as it were, intermediate between
L. violacea and L. hirta ; some forms approaching the former so as to be
essentially distinguished only by the many-flowered peduncles, more hairy
legumes, and few apetalous flowers ; while others differ from L. hirta chiefly
in the purple flowers, smaller leaflets, rather shorter calyx, longer and less
villous and more pointed legumes, &c. and connect this section with the
succeeding.

leaflets roundish-oval or somewhat obovate, emarginate, pubescent or silky*

fbliolis subovatis, dec. Chonov. ! Virg.), which, as our most esteemed friend
Dr. Boott first observed, is Linnaeus's own H. violaceum, while the synonym
of Gronovius, adduced under the latter species, belongs to Psoralea mehlo-
toides ! But the reference to Mill. diet, m the second edition of the Species
Plantaram doubtless relates to the present species.



Arachis hypogea (the Pea-nut) was sent in the late Mr. Drummond's collec-
tion, from Covington, Louisiana ; bat the specimens were doubtless cultivated.

Psoralea, Lnm. should doubtless be referred to the tribe Hedysares ; as Mr.
Bentham has suggested.
