Rydberg : Rocky Mountain flora 5e39 



mens were originally referred, B. Flodmanii differs from B. 

 marghiatus latior \}ci the scabrous, not pilose floral glumes, and the 

 narrow inflorescence ; from B. aleiiteiisis it differs in the shorter 

 awns, the smaller florets, and the less open inflorescence, and from 

 B. Hookerianus in the smaller spikelets, shorter awns, and narrower 

 scarious margins of the floral glumes. It agrees very well with 

 the description and figure of CcratocJdoa brcviaristata Hook., but 

 the palet is nearly as long as the floral glume.
