Culms 2.5 to 5 km es erect or ascending, and somewhat geniculate at the lower 
nodes. Culms terete, smooth and ascending, striate above.. Nodes glabrous, 
Sheaths glabrous, striate, closely enveloping the culms, 3 than the inter- 
nod almost obsolete. Blades 8 to 15 cm. long, 2 to 3 mm. wide, rather 
i 
gent, 10 to 15 mm. long. Flowering glume 8 to 9 mm. long, glaucous, rounded 
on the back, lanceolate, entire, or minutely 3-toothed at the apex, with a stout, 
scabrous, divergent awn 2 to 4 em. long. Palea as long as its glume, obtuse 
arginate, scabrous on the margins above. Joints of the rachis, 5 to 7 
mm. lon 
collected by P. A. Rydberg, No. 3381, Barker, August 17, 1896. 
The habit of this grass resembles that of pect boy pedet Beal; the spikelets 
and 3 glumes are arranged as in Elymus, but the ner vation of the empty 
gl trifid flowering glume, and the rachis dehiscent at the nodes, are suf- 
: tielont oliarscters to throw this species into Sitanion.

3.5 cm. First flowering glume 10 to 12 mm mm. long, entire or 2-toothed at the apex, 
rminating in a straight or very slender awn about 5 cm. long. Palea about 
the length of the glume, minutely scabrous on the sh s. keels except at the 
base, slightly pubescent at the truncate or 2-toothed apex.”

Related to S, anomalum, but taller and more slender, with mostly single rather , 
remote spikelets, which are longer.
