This may be the P. compressa, Walt, but is very distinct front 

 specimens of P. compressa, Lin. as sent me by Dr. Muhlenburg. Dr. 

 M. noticing a specimen of this grass which I had sent him, says, " it 

 appears to be my flexuosa, but as Smith has a flexuosa, we may naue 

 It A-utmnnahs." The Doctor has retained flexuosa in his catalogue ; 

 ''^tas there is nothing flexuous to be observed in my specimens, the 

 plant on the contrary being unusually erect, I have used the name en- 

 tered in my herbarium. 



. Flora specimens sent by Mr. Herbemont, from Columbia. Found 

 >n Georgia by Dr. Baldwin.
