Hedysarum hirtum L. Sp. PI. 748. 1753. 

 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 

 apexj 6"-2'' long ; peduncles mostly elongated, often 

 much exceeding the leaves ; heads oblong-cylin- 

 dric, rather dense, Y-iY 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. Aug.-Oct. 



A plant known as Lespedeza hirta oblongifdlia 

 Britton, with leaves oblong, obtuse, 9"-i5" 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. J., and in the Southern States, may be a hybrid 

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

 its fruit.

Stifif, erect or ascending, mainly simple and

 leaves nearly sessile ; leaflets oblong, linear- 

 oblong or narrowly elliptic, obtuse or acute at 

 each end, I'-ii' long, z's" wide; peduncles 

 much shorter than the leaves, or the dense 

 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- 

 nesota, Nebraska, Arkansas and Louisiana. Races 

 differ in pubescence and in width of leaflets. 

 Aug.-Sept. Dusty-clover. 

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

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

 L. capitata or a distinct species.

Erect, simple, or branched above, slender, 

 appressed-pubescent, or nearly glabrous, 

 2°-3° high. Stipules subulate ; leaves nearly 

 sessile ; leaflets linear or oblong-linear, 

 rarely some of the lower ones lance-linear, 

 l'-i4' long, i"-2" wide, obtuse, truncate or 

 acutish at the apex ; peduncles mostly elon- 

 gated, usually exceeding the leaves ; flow- 

 ers nearly as in the preceding; pod ovate- 

 orbicular, shorter than the calyx-lobes.

 Island, south to Florida, west to Louisiana. 

 Records of this species in Iowa and Michigan 

 appear to be erroneous. Aug.-Sept.
