Perennial; stem 1-2 ft., densely tufted. Leaves 12-18 in., very narrow, con- 

 volute, silkily villous towards the base; sheath glabrous or ciliate ; ligule obscure. 

 Spikes 2-4 in., purplish in Indian specimens; involucels pedicelled, pedicels villous; 

 bristles few, very unequal, one or two much longer than the rest and an inch long, 

 all free at the base. Trinius refers to P. compressum, the Alopecurus hordeiformis, 

 Linn. (Cenchrus hordeiformis, Thunb., Gymnothrix cenchroides, K. & S.), which 

 appear to me to be more probably P. Alopecurus.
