of short hairs ; sheaths strongly compressed, glossy, usually glabrous ; blades 

 sparsely hairy on upper surface near base, three-eighths to one-half inch

This grass closely resembles the field and smooth paspalums, from which it is distin- 

 guished by its hairy ligule and rootstocks, and also false redtop, from which it differs in 

 the presence of rootstocks.

A slender, tufted annual ; leaves rolled in the bud ; collar narrow, hairy ; 

 auricles none; ligule a fringe of hairs; sheaths slightly compressed, gla-
