 AL. u)iiseius R. & S. — Ea Chuparosa, October 17 (60). 



7a. . Var. breviglumis, n. var. Spikelets two in 



each cluster, one hermaphrodite, the second reduced to a pair 

 of aristiform empty glumes and a linear, triaristate floral 

 glume. The empty glumes of the perfect floret very short and 

 narrow so that the glumes appear to be awn-like from the base, 

 subequal and about the length of the triaristate flowering glume. 

 This is unlike any other form which I have, the nearest approach 

 to it being No. 247 E- Palmer (1S86). The details of the spike- 

 lets in this genus vary so much that I hesitate to give this plant 

 specific rank. — Saucito, October 14 (69).
