margin, awn-tipped, the central lobe 

 consisting of the awn, ciliate below, 

 somewhat exceeding the lateral ones; 

 palea much narrower and somewhat 

 shorter than the lemma; fertile lem- 

 ma similar to the sterile ones, the 

 palea broad and as long as the lem- 

 ma; upper sterile lemma on a rachilla 

 segment about 3 mm. long, reduced 

 to 3 plumose awns; grain compressed, 

 2 mm. long. % — Deserts, Utah, 

 Nevada, and California (Death Val- 

 ley), apparently rather rare, but 

 reported as common and sometimes 

 the dominant grass in desert regions 

 in Elko and White Pine Counties, 

 Nev.

 culms and foliage harsh-puberulent ; 

 sheaths broad, firm; blades coarser 

 than in B. kingii; panicles dense, ob- 

 long, 1 to 3 cm. long, the blades not 

 exceeding the panicle; glumes about
