Plant about 1J foot high. Leaflets H inch long and nearly one inch in diameter
Stipules lanceolate. Racemes 15-20-flowered. Calyx clothed with
ong blackish hairs, decidedly shorter than the corolla (scarcely shorter, Hook-

elliptical, membranaceous, pubescent, entirely covered by the enlarged ca-
f -eeoramg to Hooker the leaves are sometimes 5-fol’iolate, but Mr. Nut-
tall informs us that he found them invariably 3-foliolate. Hooker also describes
the corolla as scarcely exceeding the calyx, whereas we find it to be
nearly twice as long; so that his plant is perhaps a distinct, but nearly allied
species to ours. 1
25. P. orbicularis (Lindl.): pubescent, the hairs mixed with small cla-
vate truncate glands; stem prostrate and creeping; leaves 3-foliolate, on very
long petioles ; leaflets roundish-oval; peduncles as long as the leaves; spikes
capitate; bracts (dblong) and calyx very hirsute; lowest tooth of the calyx
much the longest. Lindl. bot. reg. t. 1971.

bracts clothed with blackish hairs. Flowers purple. Legume ovate
black, glabrous, with a short point. Lindl.—Our ft. differs in several respects
from the figure and description of Lindley here quoted, but these were taken
from cultivated specimens.

Calyx obconical-campanulate, 5-toothed or 5-cleft, persistent. Vexillum
concave, unguiculate, erect: wings and keel wanting. Style filiform. Stamens
exserted, monadelphous at the base. Legume oblong, a little curved, or
lunulate, longer than the calyx, roughened or tuberculate with glands, tardily
dehiscent, 1-2-seeded. Seeds oblong-oval, or slightly reniform.—Shrubby or
suffruticose plants (all North American). Leaves unequally pinnate: leaflets
numerous, punctate with pellucid (at length mostly brownish) dots, usually
stipellate. Stipules caducous. Racemes spiked, virgate, terminal, often aggregated
or paniculate at the summit of the branches. Flowers much crowded,
bluish-violet or nearly white: pedicels articulated with the flower.

oblong or elliptical, petiolulate, dotted, the lowest pair approximated to the

Wilmington, N. Carolina, Curtis ! Newbern, Croom ! July.—Shrub 4-5
feet high. Leaflets smaller and more numerous than in A. fruticosa. Calyx
subsessile, glandular. Style hairy below.—Intermediate between the preceding
species and A. herbacea ; resembling the latter in the leaves and very
short pedicels. We find considerable diversity in the calyx-teeth even in
the same specimen. Commonly, perhaps, the 3 lower teeth are abruptly alternate
into a subulate cusp, and the 2 upper very obtuse and short ■ but
sometimes the middle one of the 3 lower teeth only is cuspidate, and again
they are all short and acute. This and the succeeding species require a careful
examination in the living state, or with more complete materials than we
at present possess.
