Superficially resembling P. coarctata and P. vaginata. Differing

involute leaves, and from P. coarctata also in the pubescent nerves of 
the lemmas.

strongly scabrous: lemmas thin. 
lata bidentata nervis ciliatis, ciliis imis longioribus; antheris 0.9-1 mm. 
longis; caryopsibus 1.4-1.6 mm. longis. 
Caespitose perennial (?) 4.5-6 dm. high, green: cauline leaves with 
blades thin, flat, 3-6.3 mm. wide, 0.4-1.4 dm. long; the upper longer 
than the lower; basal sheaths purplish; ligule 1.5 mm. long, obtuse:

A rather unique plant, perhaps nearest. to the local P. nutkaensis 
of Vancouver Island, from which it differs in its softer and more 
pubescent lemmas.
