5. Lespedeza Stuvei, Nutt. 

 Lespedeza Stuvei, 'Nuit. Gen. ii. 107 (1818). 



Erect or ascending, simple and wand-like or sometimes 

 slightly branched, densely velvet}' or downy-pubescent all over, 

 2°_4° high. Stipules subulate, 2"— 3" long ; petioles 

 commonly much shorter than the leaves ; leaflets oval, oblong 

 or suborbicular, obtuse or retuse at the apex, narrowed or 

 rounded at the base, G" — 10" or rarely 15" long ; flowers of 

 both kinds in nearly sessile, axillary clusters ; corolla jDiirple, 

 2" — 3" long ; pod ovate-oblong, acute, 2" — 3" long, downy- 

 pubescent. 



Dry soil, Long Island [Wheelock] to Virginia, west to Michi- 

 gan, and Missouri. 



The species is represented among the Gronovian plants at the 

 British Museum by a specimen from Clayton with the following 

 label : " Medicago cavile erecto, vix ramoso, racemo dense 

 spicato terminato, Gron. Fl. Virg. 86." It does not seem to 

 have been taken up by Linnaeus. 



Var. angustifolia, n. var. 



Leaves linear or linear-oblong, obtuse, mucronulate. 



New Jersey and Southern Pennsylvania to North Carolina, 

 Missouri and Texas. 



Both the species and the variety have the habit of developing 

 pubescent hard obliquely ovoid bodies 1" — 2" long at the 

 t)ases of some of the leaves; these I take to be abortive 

 branches. I have observed them on L. reticulata as well. 



It is possible that further collection and study of these two 

 forms may afford characters sufficient for the recognition of the 

 variety here proposed as a species. It has been suggested that 

 Stuvei is a hybrid between violacea and hirta, but I see no proba- 

 bility of this being true.
