about 4“ long and 1/2—3/4 broad, 7—14-flowered. Glumes thin mem- 
branous, the empty ones as long as their next florets or the lower one 
a little shorter, both ovate-lanceolate, 1-nerved, and nearly smooth at the 
keels. i ayilign glumes broad ovate-obtuse or almost obovate, with hyaline 
margins and rounded or truncate, even denticulate apex, smooth at the

above but evanescent or running into the truncate apex. Paleae as long 
as their glumes, obtuse or truncate, nearly glabrous. Styles distant.

florets, the lower narrow, the upper sometimes with a lateral nerve. Flowering
