P. saltwensis is very similar in aspect to P. debilis Torrey, but the 
latter species has usually shorter, obtuse and much firmer chartaceous 
lemmas; broader glumes with mostly scabrous keels; longer cauline 
ligules (usually 2-2.5 mm. long); and smaller anthers (0.6-0.8 mm. 
long). P. saltuensis, var. microlepis has the spikelets as small as in 
P. debilis, but they maintain the acute lemmas and the anther-measure-

boreal. In distribution P. saltuensis is much more northern and 
eastern than P. debilis, the latter species extending from Vermont, 
Worcester Co., Massachusetts, and northern Connecticut through 
New York and Ohio to Michigan and Wisconsin. In central New 
York, where both species occur, P. saltuensis is found in the uplands 
associating with plants of boreal distribution, while P. debilis is a
