Agropyron divergens inermis Scribn. & Smith, var. nov. Empty glumes unequal,
narrowly lanceolate, acute, 4 to 6 lines long; flowering glumes 5 to 6 lines long,
smooth, flattened on the back, acute or acuminate, awnless or tipped with a
straight or spreading, but not divergent, awn shorter than the glume. Distin-
guished from the species by its more slender and more densely csspitose culms,
setaceous-convolnte leaves, and muticous or short-awned flowering glumes; after
flowering the spikelets very soon break up.

from British Columbia: 98a John Macoun, Yale, 1889, Columbia Valley, July 10,
1885. Washington: 1913,1914,1915,1916 Piper, 1894; Sandberg and Lei berg, 237,

There is also a single specimen, 469 Rydberg, 1891, collected in Banner County,
Tiebr., and distributed as Agropyron tenernm, var., which differs only in having
the bases of the culms clothed with dead leaf sheaths. There are »Iso two
specimens from Washington, Dr. Vasey, Cascade Mountains, 1889, and 1166
Suksdorf, 1889, which apparently connect this variety and the species. The
spikelets are very much compressed, and the culm leaves are from 8 to 12 inches
long.
