Hab. Carlton House Fort on the Saskatchawan. Drummond. — The foliage, culms, and general aspect of 

 this plant are quite the same as those of Dr Torrey*s P.fasciculata : but the panicles have more regularly 

 erect and shorter branches, and the glumes are longer and sharper. It is probably a distinct species.
