 Lespedeza hirta Hornem. Hort. Havn. 699. 1807. 



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' long ; peduncles mostly elongated, often 

 much exceednig the leaves ; heads oblong-cylin- 

 dric, rather dense, Y-iV 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. 



Dry soil, Maine and Ontario to Florida, Minnesota. 

 Arkansas. Louisiana and Texas. AuR.-Oct. 



A plant known as Lcspedeca hirta oblongifolia 

 Britton, with leaves oblong, obtuse, 9"-i5" long. 

 2"-4" wide, plabrate above, appressed-pubescent 

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

 calyx verv pubescent : in pine-barrens. Egg Harbor, 

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

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

 its fruit. ^ .

 leaves nearly sessile ; leaflets oblong, linear- 

 oblong or narrowly elliptic, obtuse or acute at

 globose-oblong heads sessile in the upper axils; 

 flowers all complete; corolla yellowish-white, 

 with a purple spot on the standard, 3" long; 

 pod ovate-oblong, pubescent, about half as 

 long as the calyx-lobes. 



Dry fields, Ontario and Maine to Florida, Min-

 differ in pubescence and in width of leaflets. 

 Aug.-Sept. Dusty-clover. 

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



Illinois and Kentucky, has linear to linear-lanceolate acute leaflets, and is a well marked race of
