Elymus glaucus var. tenuis Vasey (Contrib. U.S. Natl. Herb. 1: 280. 1893). 

 "Type specimen collected by John Macoun on Vancouver Island in 1887 (no. 3)" 

 comprises two forms, all Macoun's no. 3. One specimen is a small form of E. 

 glaucus var. jepsoni; the others have spikes with fragile rachises, spikelets with 

 5- to 6-nerved glumes and lemmas with divergent awns and apparently represent 

 a form not found in the United States. There is another Macoun specimen upon 

 which Vasey has written the varietal name tenuis, this specimen having glabrous 

 sheaths and divergent awns. The description states that the sheaths are glabrous 

 or pubescent and that the awns are divergent. Hence the plant of number 3 

 with divergent awns is selected as the type of E. glaucus var. tenuis and the name 

 is excluded from our flora.
