sharply epinastically reflexed, somewhat loose, about 1 in. long, 
6-8-awned per pair, greenish, variously tinged with purple or brown,

in the fork, tips truncate, shortly bearded, without an appendage ; 
joints filiform, very obliquely truncate, up to almost 2 lin. long, 
shortly silkily ciliate : pedicels similar, more slender and slightly 
shorter. Homogamous pairs of spikelets 1 at the base of each raceme . 
Fertile spikelets linear-lanceolate to linear-oblong, 4 lin. long including 
the callus, glabrous ; callus slender, acute, 1 lin. long, grooved on 
the back, very shortly bearded. Glu,mes equal, chartaceous ; the 
lower minutely truncate and 2-denticulate, very smooth and some- 
what glossy on the back, finely 11-13-nerved, with the nerves very 
obscure except in transmitted light, margins narrowly involute, 
keels very fine and obscurely scaberulous towards the tips ; upper 
glume obliquely truncate, sometimes mucronulate, 3-nerved, sparingly 
ciliate. Lower floret reduced to an oblong obtuse 2-nerved spreadingly
