ner ones i' or more long and the outer very short, pubes- 

 cent with ascending short hairs, the nodes in the lower 

 part of the spike about 9" apart; spikelets about 2" long, 

 lower glumes spreading in flower, equal, the lower i- 

 nerved and nerve very prominent and green, ovate-lance- 

 olate, simply acute, glabrous and hyaline except the very 

 scabrous nerve, usually; upper glume the same but with 

 two additional nerves extending only to the middle, occa- 

 sionally these are wanting; palet barely shorter than the 

 others, 2-toothed, lanceolate, very faintly 2-nerved, glab- 

 rous, simply acute, like the others very thin and hyaline; 

 floral glume ovate-lanceolate, 4-toothed at apex, faintly 

 4-nerved, scabrous throughout, equaling the palet; awn 

 attached below the middle, straight, shorter than the 

 glume; hairs ^ the palet, sparse. This is manifestly al-
