Grows from Anticosti Island and Maine to British Columbia, 
south in the mountains to New Mexico and California. 
S. depauperatus (Torr.) Scribn. is a plant of the extreme north- 
west, occurring in Washington and Oregon, possibly extending 
southward in the mountains. The culms are short and decum- 
bent, the internodes very short, usually 14’ long or less, the nodes 
often swollen; the empty scales broad, thin, white, delicate in 
texture, obtuse or acutish, more than one-half the length of the 
broad flowering scale, sometimes about equalling it. 
In S. cuspidatus (Torr.) Wood the empty scales are acuminate 
and short-awned, more than one-half as long as the acuminate 
and awn-pointed narrow flowering scale. The plant is usually 
taller and has much longer leaves than either of the two species 
above mentioned, and ranges from Manitoba to the Northwest 
Territory, Missouri and Kansas.

Nuttall’s name for this plant is the oldest, and is here taken 
up. This grass extends from Illinois westward and southwest- 
ward, and is not known to occur in South Carolina or Georgia, the 
Tegion covered by Elliott’s Botany. It could hardly, therefore, 
be the same as the Poa éenuis of that work, which, according to a 
Specimen of that plant in the Columbia College Herbarium, 
labeled as coming from Elliott, is apparently the same as 
the grass now known as &ragrostis capillaris Nees, and 
which well accords with the description given by Elliott of his 
Poa tenuis.
