we V 138. Panicum pseudopubescens Nash. 
Panicum pseudopubescens Nash, Bull. Torrey Club 26: 577. 1899. ‘Type collected 
at Auburn, Lee Co., Alabama, May 7, 1898, by Messrs. F. 8. Earle and C. F. Baker, 
No. 1537.” The type, in Nash’s Herbarium, is a clump of'a few vernal, mostly imma- 
ture culms. Some of the blades are nearly naked along the middle of the upper 
surface. Other specimens cited by Nash under this species, Karle & Baker 1522, 
1524, 1526, 1529, have narrower blades than the type, with the upper surface often 
nearly glabrous; these represent the more usual form of the species. 
This species was described by Elliott ¢ as P. pubescens Lam., as shown by the speci- 
men so labeled in his herbarium. The culm of this is appressed-pubescent, not ‘‘ very 
glabrous,’ as stated in the description. 
The species described in Gray’s Manual © under P ovale Ell. is P. pseudo pubescens.
