The original description of Glyceria pauciflora does not apply well to our plant, but the 
name is here used as commonly applied. An examination of the type will doubtless 
show it to be different, perhaps not of this genus.

Specimens collected by Tweedy and Brandegee and referred by Professor Scribner to 
Glyceria pallida @ are probably a pale form of P. nervata. As we have not been able to find 
the specimens this is purely surmise.
