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. S. 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, Earle & 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 a 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. pseudopubescens.
