This plant appears to be specifically distinct from the P. ads- 
tans Parl. The taller and more slender culms, the panicle- 
branches dividing nearer the extremities, the fewer and less 
crowded spikelets, and the comparative length of the empty and 
flowering scales serve well to distinguish it. In P. distans, a coast 
plant, the second empty scale is less than one-half as long as the 
flowering ones ; while in P. airoides, a plant of the western interior, 
it exceeds one-half the length of the flowering scales.

~ Bromus Porrert (Coulter). 
Bromus Kalmii var. Porteri Coulter, Man. Rocky Mt. Region, 
425. 1885. 
Culms 1 14°-3° tall, erect, simple, pubescent below the nodes. 
Sheaths shorter than the internodes, glabrous or sometimes softly 
pubescent; ligule 14” long, truncate; leaves 1/’—3/’ wide, rough, 
those of the culm 4’-9’ long, the basal narrow and about one- 
half of the length of the culm; panicle 3/—6’ in length, its branches 
drooping and flexuous, at least when old, the nodes of the axis 
pubescent; spikelets 5-10-flowered, 9/’-15” long, on slender 
flexuous pedicels; empty scales pubescent, the first narrower than 
the second, both 3-nerved ; flowering scales 5’’-6”’ long, obtuse, 
5-7 nerved, densely pubescent with long silky hairs; awn 1/-2” 
long. 
In dry soil, South Dakota to Montana, south to western Ne- 
braska, New Mexico and Arizona. 
This plant is readily distinguished from B. Kalmii by its 3- 
nerved second scale and longer flowering scales. In B. Kalmit 
the second scale is 5~7-nerved and the flowering scale about 4” 
long.
