Erect or ascending, rather stout, generally branch- 

 ing above, villous or silky-pubescent, 2-4 high. 

 Stipules subulate, i"-2i" long; petioles shorter 

 than the leaves ; leaflets oval, or suborbicular, ob- 

 tuse at each end, sometimes emarginate at the 

 apex, 6"-2 v long ; peduncles mostly elongated, often 

 much exceeding the leaves ; heads oblong-cylin- 

 dric, rather dense, i'-i^' long; flowers all com- 

 plete ; corolla yellowish-white or the standard 

 purple spotted, about 3" long; pod oval, acute, 

 very pubescent, about equalling the calyx-lobes.

A plant known as Lespedeza hirta oblongifdlia 

 Britton, with leaves oblong, obtuse, 9"-! 5" long, 

 2 "_4" wide, glabrate above, appressed-pubescent 

 below; peduncles slender; spikes looser, i'-ij^' long; 

 calyx very pubescent ; in pine-barrens, Egg Harbor, 

 N. ]., and in the Southern States, may be a hybrid 

 with L. angustifolia (Pursh) Ell. We do not know

 Lespedeza longifolia DC. (L. capitata hngifolia T. & G.) of prairies, from Iowa to Missouri
