1. Lespedeza striata (Thunb.) H. & A. Bot. Beech ey. 



262. 1841.

 region in sterile fields and woods, and rarely extending as 

 far north as Kansas City. Probably not of this genus, as 

 the ovate calyx lobes and annual habit are clearly at variance 

 with those characters in our other species.
