Rich moist soils, Massachusetts! to-Pennsylvania! west to Kentucky!
August—Stem about'3 feet high süfcate. Leaflets 2-3 inches long, and 1-2*
inches Wide, usually ovate-oblong, rather obtuse, nearly glabrous above ; the
pubescence of the lower surface not scabrous to the touch. , Stipules, much
smaller than in the preceding species: Panicle large, nakfed ; the branches
scabrous with very minute uncinate prickles, not canescent ; pedicels 2-4
lines long : bracts deciduofts. Flowers purple, changing to bluish-green ip withering:
Legume three-fourths of an inch long; the joints distinctly rhombic
and connected by a narrow isthmus^Allied to the preceding species; but
readily distinguished by its, scabrous stem, narrow stipules, fewer joints of
the legume, &c. '
7. D. cuspidatum: Stem erect, glabrous ; leaflets ovate or lanceolate-ovate,
acuminate, glabrous ; stipules lanceolate with asubulate point ; panicle large’,
elongated, sparingly branched ; bracts (conspicuous) ovate, cuspidate ; uppers
lip of the calyx slightly bifid; lateral teeth of thelöwer lip triangular; aboutas
long as the tube, the middle one much longer, lanceolate ; .stamens perfectly
diadelphous ; legumes with 4-6 triangular-oblong hispid joints.:—D. bracte-

Banks ol rivers and borders of woods, Canada ! to S. Carolina ànd Florida !
west to Arkansas !—August.—S tem 4-5 feet high, with few branches. Leaflets
3-5 inches long, and 1-2i inches wide," tapering to a long acute point.
Stipules glabrous, deciduous. Partial stipules conspicuous, subulate. Panicle
often 2 feet long ; the racemosebranches slightly scabrous with a minute
uncinate pubescence. Flowers often sterile. Bracts large” broad at the base
with a long acute point. Corolla purplish-violet. Legume 1J-2 inches long!
8. D. viridiflorum (Beck) : stem'"erect, densely pubescent and somewhat
glabrous towards the summit ; leaflets ovate, mostly obtuse,'scabrous above
velvety-villous beneath; stipules ovate-lanceolate, acuminate, caducous ; panicle
elongated, naked ; upper lip of the calyx slightly bifid; lowest tooth lanceolate,
nearly twice as long as the triangular lateral ones; stamens somewhat
monadelphous at the base ; legumes of 3-4 obtusely triangular joints.__

Alluvial soils, Pennsylvania ! to Florida! Alabama, Zfr. Gates! Red River,
Louisiana, Dr. Hale ! Aug.— Stem 3-4 feet high, rather stout, panicu-
lately branched. Leaflets 2-3 inches long ; the lower surface clothed With a
thick and very soft pubescence. Panicle very large. Bracts small, broadly
oyate. Calyx very hairy, scarcely \ the length of the corolla. Corolla viölet-
purple, turning greenish in withering. Légume about 1J inch long; the
joints convex above, obtusely angular below.—This is the original Hedysarum
viridiflorum of Linnaeus, as has been ascertained by Dr. Boott; but not
the plant described under this name by Willdenow, Pursh, and others.
9. D. rhombifolium (D C .): stem erect, stout, minutely pubescent (rather
thick and coriaceous), reticulated beneath, ovate, obtuse, pubescent along the
veins; the lateral ones ovate-oblong, somewhat distant; the terminal rhombic-
ovate ; stipules subulate, caducous; racemes paniculate, scabrousrpubes-
cent; bracts ovate, small; lower lip of the calyx longest; the lateral teeth
acute ; legumes of 2-4 broadly semi-rhomboidal hispid-pubescent joints
slightly convex on the back, with a stipe nearly the length of the lowest joint.
—DC. prodr. 3. p. 330. Hedysarum rhombifolium, E ll.! sk. 2. p. 216.
d. more glabrous-; leaflets smaller, paler beneath and not reticulated, glabrous
or minutely pubescent on the veins.
In dry rich soil, S. Carolina! to Florida! and Louisiana! d. North Carolina!
to Louisiana! and Arkansas! Aug.-Oct.—Stem 2-4 feet high.
Petioles 1—3 inches long. Leaflets 2—3 inches long, very thick and firm,
sometimes a little narrowed towards the apex but obtuse. Panicle very
large : pedicels as long as the flowers. Joints of the legume about 3 lines
in length, scarcely convex on the back when mature.—We have a form of
this species which greatly resembles some varieties of D. viridiflorum,
except that they want the tomentose pubescence of the lower surface of the
leaves. Our smoother variety (which differs very slightly from the plant in
Elliott’s herbarium) is often taken for D. laevigatum, but it does not accord
with the character of that species.
10. D. Icemgatum (DC.): very smooth; stem simple, erect, somewhat
glaucous; leaves on long petioles; leaflets ovate, acute; stipules subulate,
minute and deciduous; panicle terminal, nearly simple ; flowers by pairs
uPon long pedicels ; bracts ovate, acute, shorter than the flower-buds. Nutt.
—DC. prodr. 2. p. 329. Hedysarum laevigatum, Nutt. gen. 3. p. 109.
“ In the forests of New Jersey, rare.—Rather large, and the smoothest of
the North American species.. Lower petioles about 3 inches long; the
larger leaflets 3 inches long and 1 i broad, every where perfectly smooth,
somewhat glaucous beneath, sometimes elliptic-ovate, constantly diminishing
in size upwards : the stem attenuated into the terminal and racemose panicle
; rachis of the panicle and the peduncles minutely pubescent: lowest segment
of the calyx conspicuously elongated. The fruit I have not seen. Allied
to H. cuspidatum but perfectly distinct.” Nutt.—We have copied Mr.
Nuttall’s description entire, not having seen this species, unless we have
mistaken it for a form of D. cuspidatum, from which it appears to differ only
in having smaller stipules and bracts. Elliott’s plant is, we suspect, not
distinct from D. cuspidatum.
11. D. glabellum (DC.): stem erect, nearly glabrous; leaflets (small)
ovate, obtuse, scabrous-pubescent on both sides ; stipules subulate, minute ;
panicle terminal; upper lip of the calyx entire ; the lower tooth longest;
legume stipitate, nearly straight on the back, minutely hispid, with about 4
semi-rhomboidal reticulated joints.—DC. prodr. 2. p. 329. Hedysarum
glabellum, Michx.! fl. 2. p. 73 ; Ell. sk. 2. p. 2 1 1 ; not of Pursh.
In shady places, S. Carolina, Michaux! Elliott. N. Carolina, Mr. Curtis
! August-Sept.—Resembles D. Marilandicum in foliage, although the
leaflets are often much larger and scabrous with appressed hairs, but the
legumes are very like those of D. paniculatum. We have apparently a
larger form of this species from Florida, but the fmit is wanting : perhaps it
is rather a small-leaved D. Dillenii.
12. D. Marilandicum (Boott! mss.): stem erect, simple, slender, nearly
glabrous; leaflets (small) ovate, very obtuse, often slightly cordate, thin;
petioles as long as the lateral leaflets, glabrous; stipules lanceolate-subulate,
caducous; panicle elongated, scabrous-puberulent; bracts lanceolate-ovate,
very small; upper lip of the calyx rather shortest, emarginate; the lower
