Woods, Pennsylvania! Western States! Arkansas! Louisiana! Au£rust. 

 — Stem a foot or more in height, sometimes a little branched, slender. Leaf- 

 lets 1-3 inches long, pale beneath, thin, spiinkled with short hairs. Flowers 

 few (4-10), in a loose raceme or panicle: pedicels about one-third of an inch 

 long. Teeth of the calyx nearly equal. Corolla pale purple or nearly white. 

 Legumes resembling those of D. nuditlorum, but the joints are less angular. 



§ 2. Stamens diadelphous (or with the tenth stamen connected with the oth- 

 ers onlij near the base) : calyx bilabiate, cleft below the middle: le- 

 gume mostly sitbsessile. 



4. D. Canadcnse (DC.) : stem erect, hairy, striate; leaflets oblong-lanceo- 

 late, nearly glabrous or strigosely pubescent ; stipules subulate ; racemes ter- 

 minal and in the axils of the uppermost leaves ; bracts ovate-lanceolate, with 

 a long acumination; calyx deeply bilabiate; upper lip oblong, bifid at the 

 apex, the lower 3-parted; the segments lanceolate; joints of the legume semi- 

 ova.-triangular, truncate at both ends, hispid. — DC. prodr. 2. p. 328; Hook.

Dry Woods, Canada ! (as far north at lat. 54'", Hook.) to Pennsylvania! 

 Western States ! August.— Stem 2-3 feet high, robust, often villous or hir- 

 sute. Leaflets 2-3 inches long, tapering to the summit, but rather obtuse 

 Racemes numerous, erect, forming a panicle at the summit of the stem. 

 Bracts imbricated, and very conspicuous before the flowers are expanded. 

 Stamens diadelphous the upper third of their length. Legume about one 

 inch long ; the joints convex on the upper side, rounded and obscurely angu- 

 lar below. 



5. D. canescens (DC): stem erect, branching, striate, hairy and scabrous, 

 particularly above ; leaflets ovate, rather acute or slightly acuminate, scabrous, 

 pubescent on both sides; stipules large, obliquely ovate, acuminate, finely 

 striate, ciliate, persistent; panicle large, very hairy, canescent; bracts ovate- 

 lanceolate, deciduous, ciliate ; upper lip of the calyx entire or slightly bi- 

 fid at the apex; segments of the lower lip lanceolate, the middle one 

 narrow ; stamens diadelphous nearly to the base ; legumes of 4-6 oblong-tri- 

 angular reticulated hispid joints.— '/>C. prodr. 2. p. 328 ; Beck. bot. p. 84 ;

Moist rich soils, particularly along rivers, Massachusetts! and New-York! 

 to S. Carolina ! and Florida. July-Aug.— Stem 3-5 feet high, rather stout, 

 more or less hairy, the pubescence partly very short and consisting of unci- 

 nate hairs. Leaflets 2-4 inches long and 1-3 inches Avide ; the terminal one 

 usually somewhat rhombic, but often roundish, paler beneath, covered with 

 a minute uncinate pubescence on both sides. Stipules 4-5 lines long, striate, 

 scarious. Flowers in large paniculate racemes, which are terminal and axil- 

 lary in the upper part of the stem; the branches densely clothed with canes- 

 cent spreading hairs: pedicels 3-6 lines long, solitary or in pairs. Calyx 

 hairy, deeply bilabiate; the segments all acute. Corolla about 3 times as 

 long as the 'calyx, violet-purple, becoming greenish in Avithering. Legume 

 1-fi inch long, 'usually 3-5- (sometimes 6-) jointed ; the joints convex on the 

 upper side, obtusely angular below, truncate at both ends : stipe scarcely as 

 long as the calyx.
