been consiJere 1 as a sterile form of E. Emersleyi but I have 

 plenty of material with fertile florets. The general habit is that of 

 Emersleyi but the florets are oblong, the glumes ovate to lanceolate 

 or 8 vmtirnM oblong, mostly acute arid even short-awned, though 

 in the number cited they are erase and obtuse, mostly a little 

 shorter than the lemma, mostly evidently nerwd. The lemma is 

 oblong with the nerves clost^ together, very scabrous but not hairy 

 the awn a mere thickening <»f the central nerve at the tip or a 

 knob or a fine awn nearly as long as the lemma. I he sterde forms 

 are without awns. This is E ligulata Scribner and it abounds 

 from Black's Peak New Mexico (Diehl) both eastward and west- 

 ward through Arizona to the '[San Jacinto Mts. California and 

 southward.

 rest this genus on those species with rat-tail-like spikes a foot or

 coarse ribs- The rays are very short (except the very lowest) and
