longer: inflorescence often dense: clusters of both kinds of flowers nearly sessile or short- 
[Une in the axils, usually crowded near the summit of the stem: calyx-lobes 3 as 
ong as the pod or shorter: corolla violet-purple, 4-6 mm. long: pods ovate-oblong, 
about 4 mm. long, acute, pubescent, surpassing the calyx-lobes. 
In dry soil, Massachusetts to Ontario, Michigan, Florida and Texas. Summer and fall. 
13. Lespedeza Virgínica (L.) Britton. Perennial, similar to L. frutescens, but more 
slender. Stems erect or ascending, 4-11 dm. tall, simple or sparingly branched: 
leaflets 3, the blades linear or oblong-linear, 12-35 mm. long, truncate, obtuse or some- 
times acute at the apex, glabrate on both surfaces or finely pubescent beneath : inflorescence 
rather dense: clusters of both kinds of flowers sessile or nearly sessile and crowded in the 
upper axils: calyx-lobes less than 3 as long as the pod: corolla violet-purple, 4-6 mm. 
long : pods ovate or oval-orbicular, about 4 mm. long, acute or obtuse, pubescent or glabrate, 
surpassing the calyx-lobes. 
In dry soil, Massachusetts to Minnesota, Florida and Texas. Summer and fall. 
14. Lespedeza hirta ( L.) Ell. Perennial. Stems erect or ascending, 5-12 dm. tall, 
mostly branched above: leaflets 3, the blades oval or suborbicular, 12-40 mm. long, 
rounded at both ends or notched at the apex: racemes rather dense, 1-4 cm. long, dis- 
posed in panicles : peduncles often surpassing the leaves: flowers all complete :_ calyx-lobes 
surpassing the pod : corolla about 6 mm. long, yellowish white ; standard sometimes an ot 
spotted: pods oval or obovate, 7-8 mm. long, acute, about as long as the calyx-lobes. 
.. In dry soil, Maine to Ontario, Minnesota, Florida and Louisiana. Summer and fall.—A variety 
with loose spikes, a densely pubescent calyx and leaflets with oblong blades, is L. hirta oblongifolia Brit- 
ton; it ranges from New Jersey to the Gulf States. 
15. Lespedeza capitata Michx. Perennial, silky or silvery pubescent. Stems 
erect or ascending, rigid, 5-16 dm. tall, usually simple to the inflorescence : leaflets 3, the 
blades oblong to oval, 2.5-3.5 em. long, obtuse, or acute at both ends, several times longer 
than the very short petioles: flowers all complete: racemes oblong-globose, sessile or 
short-peduncled : calyx-lobes much longer than the pod: corolla about 6 mm. long, yel- 
lowish white, or standard with a purple spot: pods oblong-ovate, 5-5.5 mm. long, acute,
