Sandy pine woods, North Carolina! to Florida!— Stem about 2 feet hieh. 

 Lrallets 6-S lines lonff, the lower ones obtuse or retuse. Stipules extremely 

 minute, deciduous. Pedunelos often twice the length of the leaves. Flow- 

 ers spreadin<j or reflexcd, wiiitish, 7-S lines lone;, slender. Calyx pubescent, 

 about one-tlurd the leuijlh of the corolla. Legume li inch long, somewhat 

 tumid.— Perhaps not properly referred to this section; as we arc not certam 

 that the flowers arc ochroleucous. The subdivision Dissitijlori, of De 

 CandoUe's first section, is the only one to which it has much resemblance ; 

 and from this it is excluded by its curved legumes.

37. A. racemosus (Pursh) : erect or assurgent, somewhat pubescent ; leaf- 

 lets about 10 pairs, elliptical-oblong; peduncles longer than the leaves; flow- 

 ers in dense spikes, nodding and somewhat secund ; calyx oblong; the teeth 

 subulate, more than half the lengtii of the tube ; legumes pendulous, ellipti- 

 cal-oblong, triquetrous, acute at each end. glabrous, l-celled, the lower suture 

 deeply inflexed.— P;/r.5/j, ft. 2. p. 7-10; DC. prodr. 2. p. 294. A. galegoides,

Saline soils, from the banks of the White River to the Rocky Mountams, 

 Nuttall. On the Platte, Dr. James .'—About 2 feet high, minutely pubes- 

 cent. Leaflets 6-8 lines long, rather acute. Stipules lanceolate, membra- 

 naceous. Spikes racemose, many-flowered: pedicels about 2 lines long. Ca- 

 lyx pubescent. Legume (including the stipe) about 15 lines long and 3 lines 

 wide, the stipe scarcely one-third the length of the fertile portion.— A. gale- 

 giformis, Linn, diflers in being glabrous ; in the broader and much shorter 

 teeth of the calyx; the 2-celled smaller and more ventricose legume; and in 

 the much longer stipe. 



38. A. Drummondii{I>ong\.): tall and erect ; stem, peduncles, and leaves 

 clothed with soft hairs ; leaflets 12-15 pairs, linear-oblong and oblong, nar- 

 rowed at the base; stipules ovate, much acuminated ; peduncles longer than 

 the leaves ; spikes elongated, loose ; bracts subulate, longer than the pedicels; 

 flowers pendulous and somewhat secund; teeth of the calyx subulate, about 

 half the length of the tube; legumes recurved, cylindrical, glabrous, a little 

 falcate, partly 2-celled; the upper suture obtuse, the lower deeply inflexed.— 

 Hook. jl. Bor.-Am. 1. p. 153, t. 57. 



Hudson's Bav, and on the Saskatchawan, Donglas .' Grassy places by 

 streams, near the sources of the Platte, Nuita/l .'—Stem 1-2 feet high, rather 

 robust. Leaflets i-1 inch long. Raceme 3-4 inches long. Legumes carti- 

 laiinous, when mature 2 inches in length ; the stipe slender and about one- 

 fifth the length of the pod.— Very near the preceding species, but quite 

 distinct. 



§ 3, Stipules more or less cohering with the petiole ; ihepetiole not indu- 

 rated and spinose. — Podochreati, DC. 



39. A. mollissimvs (Tort.): silky-villoUs, nearly stemless, erect ; leaflets 

 11-14 pairs, ovate-oblong; stipules triangtilar-ovate. partly adhering to the 

 petiole ; peduncles mostly longer than the leaves ; fl^ow^ers in long racemose 

 spikes, somewhat erect; calyx cylindrical; the teeth subulate, half the length 

 of the tube ; legumes cylindrical-oblong, coriaceous, curved, glabrous, 2-cel- 

 led, moderately grooved along each suture.— Ton\ .' in ann. lye. New-York,
