0. large, nearly glabrous ; leaflets oval-oblong, tapering at each end, par- 

 ticularly at the base, rather obtuse ; 'the terminal flowers two or three 

 together. 



"y. more pubescent; leaflets cuneiform-obovate, often retuse ; the lower 

 flowers axillary ; the others usually forming short racemes at the extremity 

 of the branches ; bracts of the upper flowers subulate, as long as the pedicels.

 April-June. — Plant 2-3 feet higli, the minute pubescence appressed. Leaves 

 coriaceous. Flowers large. Teeth of the calyx short, triangular, acute ; the 

 upper one larger, obtuse or emarginate : in 0. all rather obmse. Ovary very 

 villous. Legumes large, at first silky-villous, ovate-lanceolate.

North Carolina, Michaux! Mr. Curtis ! Arkansas, Nuttall ! June- 

 J\x\y. — Plant rather large. Stem branched, pubescent with minute appressed 

 hairs. Leaflets 2-3 inches long, obtuse, attenuate at the base and almost 

 petiolate, villous-pubescent when young, especially beneath. Pedicels 

 shorter than the flowers ; which are about the size of those of B. lanceolata. 

 Calyx somewhat villous-pubescent with appressed hairs ; the teeth acute ; 

 the upper one slightly notched. Ovary very woolly. — We have drawn up 

 our description from the specimen of Mr. Curtis, which we think is the same 

 with the plant of Michaux. We are doubtful, however, whether it be the 

 Sophora villosa of Walter, in whose herbarium a portion of a raceme of the 

 plant only exists ; and in this the calyx is more villous. Elliott seems to be 

 unacquainted with the species, and this is probably also the case Avith 

 Pursh. Mr. Nuttall's specimens from Arkansas agree well with the plant 

 from North Carolina, except that the lowest bracts are ovate-lanceolate, 

 foliaceous, as long as the pedicels, and persistent. We have never seen 

 the fruit. 



fi. B. spli<Erocarp)a (Nutt.) : glabrous ; leaves nearly sessile ; leaflets obo- 

 vate-oblong, obtuse, minutely pubescent when young; stipules and bracts 

 minute or almost none ; racemes spicate, elongated ; pedicels shorter than 

 the calyx (flowers deep yellow) ; legumes very short, subglobose. — Nutt. !

Plains of the Arkansas (in rather wet gravelly soil), Nuttall! Near Fort 

 Towson, Dr. Leavenicorth ! Around Little Rock, Arkansas, Dr. Engel- 

 mann ! — Texas ! .June-Julv. — Stems 2-3 feet high, many from the same 

 roots, with erect branches. Flowers large, usually in a long strict spike. 

 Teeth of the calyx short, very acute ; the upper one obtuse. Ovary glabrous. 

 Stipe short. — The fruit, according to Dr. Engelmann, is rather oval than 

 globose, and the walls remarkably hard and thick.
