Nearly allied to the preceding species, but readily distinguished by its much
less dense pubescence and conspicuously dotted leaves.

spikes cylindrical on long peduncles ; bracts awned, longer than the calyx
hairy; calyx glabrous, hairy on the margin, naked with large glands, cleft or

the lower side ; petals lanceolate-lmear; vexillum broadly cordate.

9. P. violaceum (Michx.): somewhat pubescent or glabrous: leaflets 2
pairs, linear, with a few glands beneath; spikes very dense varying from
globose-ovate to oblong-cylmdncal, pedunculate; calyx silky-canescent; teeth
about one-third the length of the tube; petals oblong, obtuse at the base, with

Dry prairies, Western and Southwestern States! and Texas! North
to Saskatchawan River. July-Aug.— 11 Root thick, somewhat fusiform,
fasciculately branched below. Stems numerous from one root, about 2 feet
high. Leaves fascicled : leaflets 6-10 lines long. Bracts obovate-spatulate,
rather shorter than the calyx, acuminate, the points nearly glabrous. Flowers
bright purplish-violet, retaining their color when dry.
10. P. carneum (Michx.) : glabrous; leaflets 2-3 pairs, lanceolate-linear,
glandular; spikes oblong, pedunculate; calyx glabrous, without glands, rather
shorter than the obovate bracts, the teeth much shorter than the tube; petals
(rose color) oblong, attenuate at the base into a long claw; vexillum oblong.

Sandy soils, Georgia, and Middle Florida, Michaux! Dr. Chapman!
0. near Milledgeville, Georgia, Dr. Boykin ! Aug.—If Stem slender, 1-2
feet high, much branched. Leaves fascicled: leaflets usually 3 pairs, about
half an inch long, acute. Spikes an inch or more in length, on long peduncles.
Calyx slightly pubescent on the margin, cleft on the upper side, the
teeth scarcely one-third the length of the tube. Petals pale (or sometimes
rather deep) rose-color; in 3. pure white.—With the exception of the white
flowers and rather narrower petals in 0., we can find no character to distinguish
it from the ordinary form.
11. P. decumbens (Nutt.) : sparingly pubescent; stem branched from the
base, decumbent; spikes ovate-oblong, thick; leaflets 3-4 pairs, linear-oblong,
mucronate, slightly dotted; calyx shorter than the acuminate bracts;
the teeth lanceolate, longer than the tube; petals linear-oblong, obtuse at the
base; claws short; vexillum cordate.—Nutt.! in jour. acad. Philad. 7. p. 93.
Plains of Red River, Arkansas, Nuttall!—If Stem about a foot long.
Leaflets 6-8 lines long and 2 lines wide. Spikes one inch long and about
f of an inch in diameter. Calyx a little pubescent, particularly on the margins
of the teeth. Corolla deep violet-purple.—Near P. violaceum; but with
larger and more numerous leaflets, a deeper-eleft calyx, narrower petals, &c.
The upper surface of the leaves turns to a verdigris-green in drying.
12. P. emarginatum: glabrous ; leaflets 7-8 pairs, cuneiform, emarginate,
dotted beneath; spikes cylindrical, on very long peduncles; bracts broadly
obovate, acuminate, longer than the flowers; calyx very villous, deeply 5-
cleft, the segments lanceolate; petals oblong, rather obtuse at the base; vexillum
oblong, emarginate.
Texas, Drummond!— Stem about 2 feet high. Leaves numerous:
leaflets one-third of an inch long, deeply emarginate. Spikes compact, on
peduncles 6-10 inches long. Bracts silky-villous ; lower ones much dilated.
Flowers bright rose-purple. Petals with short claws. Limb of the vexillum
(when expanded) somewhat 4-sided.—A very distinct species, having much
the appearance of Dalea alopecuroides. The leaves become verdigris-green
when dry.
13. P. corymbosum (Michx.): stem corymbosely branched at the summit
; spikes globose; bracts large and much dilated, the lowest ones empty
and bearing leaflets ; leaves fascicled; leaflets 2-3 pairs, linear ; calyx deeply
cleft; the segments setaceous, plumose.—Michx. ! fl. 2. p. 50 ; Pursh fl.
