Agrostis occidentalis sp. nov. 
A rather stout, caespitose, glabrous perennial, about 12 dm. 
high, with numerous linear leaves, open lax panicles and awnless 
spikelets. Culms glabrous; sheaths shorter than the internodes ; 
ligule about 4 mm. long, obtuse, somewhat lacerate ; leaf blades 
plane, 2~3 dm. long, 3-4 mm. wide, scabrous on both surfaces. 
Panicles exserted, about 1.5 dm. long ; common axis and branches 
scabrous, the latter fasciculate at the nodes, spreading or ascending, 
naked below, flower-bearing above. Spikelets pale green ; empty 
glumes subequal, lanceolate, acuminate, strongly aculeolate-sca- 
brous on the keel, 3.5—4 mm. long; flowering glume 2.5-3 mm. 
long, acute and minutely 4-toothed at the apex, bearing at the base 
a tuft of hairs one fourth to one half as long as the glume. Palea 
wanting, 
Type specimen collected by C. L. Shear, no. 1644, in a moist 
glade, McMinnville, Yamhill county, Oregon, July 20, 1899. 
This species in habit resembles Agrostis virescens H.B.K., but 
is at once distinguished by its awnless flowering glumes.

A caespitose, densely pubescent, ashy-gray perennial about 
8 dm. high, with numerous basal leaves, densely flowered spikes — 
and long-awned flowering glumes. Culms minutely pubescent ka 
puberulent throughout ; nodes puberulent, sheaths shorter than the 
internodes, densely pubescent with short hairs; ligule about ! 
mm. long, densely pubescent ; leaf-blades linear-lanceolate, firm, 
flat or with somewhat incurved margins, 1-1.5 dm. long, 5-8 ser 
wide, densely and softly pubescent with short hairs throughet 
Spike about 10 cm. long, the spikelets slightly exceeding 
internodes, and two at each node; empty glumes nearly equ ai 
linear-lanceolate, long-acuminate-awned, 1.5-2 mm. wide, me 
15 mm. long, including the awn, very strongly scabrous ON 
nerves ; flowering glumes about g mm. long, scabrous, bee
