Recent examination of the type of Panicum pubescens in Lamarck's 
herbarium, Muséum d’ Histoire Naturelle de Paris, shows that this 
species has been misinterpreted by American authors — see Scribner 
& Merrill, U. S. Dept. Agr. Div. Agros. Bul. 24: 36. 19or. 
In the Herbarium of Columbia University is a specimen referable 
to this species labelled in Torrey's handwriting “Panicum unciphyllum 
Trin. in Lit.” It is evident that this specimen was named by 
Trinius and while it is very possible that the plant in question may 
be different from the type of the species, we feel justified in taking 
up Panicum unciphyllum, rather than applying a new name to this 
very common grass. It is probable that an older tenable name will 
be found when the obscurity of many of the older species is cleared 
up, which can only be accomplished by examination of the types in 
the various European herbaria. 
This species is exceedingly variable and many varieties or forms 
might be characterized on the basis of size and habit. The follow-
