Elymus strigosus Rydb. sp. nov. 



A cespitose perennial ; sheaths 3-8 cm. long, striate, glabrous 

 or minutely puberulent, with distinct auricles at the mouth; ligules 

 very short, truncate, i mm. long or less; blades 1-2 dm. long, 

 about 3 mm. wide, flat or involute, scabrous ; culm 5-7 dm. high ; 

 spike 1-1.5 dm. long; spikelets i or 2 at each node; empty glumes 

 linear-subulate, 7-9 mm. long, very scabrous ; flowering glumes 

 lanceolate, scabrous-strigose, awn-pointed or short-awned, without 

 the awn about i cm. long. 



This is closely related to E, auibignns^ but distinguished by 

 the scabrous strigose flowering glumes, the more scabrous empty 

 glumes and the narrower leaves.

1/ Elymus villiflorus Rydb. sp, nov. 



A cespitose perennial; sheaths 4-10 cm. long, striate, gla- 

 brous ; blades 1-2 dm. long, about 2 mm. wide, strongly involute, 

 scabrous above ; culm 4-6 dm. high, finely retrorse-pubescent 

 above;' spike i-[-5 dm. long; spikelets I or 2 at each node; 

 empty glumes subulate, 7-9 mm. long; flowering glumes lan- 

 ceolate, 5-nerved, villous-hirsute, without the short awn about I 

 cm. long. 



Closely related to the preceding and E. a^nbigtins, this is char- 

 acterized by its long-haired and more strongly nerved flowering 

 glume. It grows on plains and foothills at an altitude of 1500- 

 1800 meters.
