 the attenuate calyx-lobes. 6-8 mm. long; pod ovate or ovate-oblong, 4.5- 

 6.5 mm. long, acute, canescent or short-pubescent, twice the length of the 

 calyx-lobes or less. Dry soil, Bronxville, N. Y. City. Also eastern Mass. 

 and X. J. Aug.-Sept. 



3b. Lespedeza acuticarpa Mackenzie & Bush. Erect-ascending;

 oblong to oblong-elliptic, glabrate above, densely appressed-pubescent 

 beneath, 8-30 mm. long, 4-8 mm. wide, obtuse or acutish, mucronulate;

P. 564, before Lespedeza Stuvei, insert:
