 "Type specimen collected by John Macoun 

 on Vancouver Island in 1887 (No. 3)" com- 

 prises 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 appar- 

 ently represent a form not found in the 

 United States. There is another Macoun 

 specimen upon which Yasey has written the 

 varietal name tenuis, this specimen having 

 glabrous sheaths and divergent awns. The 

 description states that the sheaths are gla- 

 brous or pubescent and that the awns are 

 divergent. Hence the plant of number 3 with 

 divergent 9,wns is selected as the type of E. 

 glaucus var. tenuis, and the name is excluded 

 from our flora.
