July-Sept.—Flowers bright yellow, large and showy.—None of our specimens
wholly accord with the C. fasciculata, Michx. W e have glabrous
forms with yellow anthers; but in these two of the petals are always more
or less spotted with purple. The var. 6. is very large in all its parts : c. is
smaller, but clothed throughout with remarkably soft villous hairs ; the var.
£. has the stem, leaves, calyx, &e. more or less cinereous-pubescent, the
flowers are rather smaller, and the pedicels sometimes shorter.—Sensitive
Pea. Partridge-Pea.
6. C. nictitans (Linn.) : annual, erect or decumbent, somewhat pubescent
; leaflets 12—30, oblong-linear, obtuse, mucronate, somewhat oblique at
the base ; gland beneath the lowest pair of leaflets 'slightly pedicellate ; stipules
and bracts broadly subulate, striate, persistent; fascicles.supra-axillary,
2~3-flowered; the pedicels very short, bracteolate ; flowers small; sepals
acuminate ; stamens 5, nearly equal; style very short.—Linn. ! 1. c. Sr hort.

Elliott! July-Sept,—Pedicels shorter than the flowers. Petals small, not
spotted. Anthers rather short, mostly all purple. Legume somewhat
hairy.—Readily distinguished by its very small flowers, short pedicels, &c.
The C. aspera of Elliott seems to be nothing but a variety of this: in the
specimen from his herbarium which we have examined, the anthers are mostly
purple. The leaves in this and the preceding are very sensitive; whence
the two species are popularly called Sensitive Pea.
C. ligustrina (Linn.) was founded on a West Indian plant (C. ligustri folio,
Plumier; Dill. Elth. t. 269, f . 338), to which the reference to Gronov. Virg.
(which belongs properly to C. Marilandica) was wrongly adduced. It seems
not to be a native of N. America; and Pursh has, as we think, inadvertently
added the mark v. v., stating that it grows in cultivated grounds from Virginia
to Georgia.
C. (Chammsenna) angustisiliqua (Lam.), or a species nearly allied to this, was
collected in Key West by Mr. Bennett, but the specimen is too incomplete for
satisfactory determination. The gland is very large and thick, commonly placed
towards the base of the petiole, but sometimes between the lowest pair of leaflets.
We have not seen the fruit.
