base ; internodes mostly 1J-2J lin. long, often irregularly longer or 
shorter ; pedicels 2-nate or solitary, very short and stout with 
truncate circular tips and usually a few bristles. Spikelets lanceolate 
to lanceolate-oblong, acuminate, 1J-2 lin. long (excluding the awns), 
green to greyish-green, often with purple tips or altogether red- 
purple, minutely and often very scantily bearded at the base. 
Glumes subequal, 1J lin. long, thinly herbaceous, lanceolate to 
lanceolate-oblong in profile, produced into slender filiform smooth 
upwards more or less viscous and purple awns, sparingly hairy, the 
lower towards the margins, the upper upwards, rarely quite glabrous, 
the lower gradually, the upper more abruptly passing into the awn, 
the lower 5-, the upper 7-9-nerved, awn of the lower up to over 5 
(occasionally 8) lin. long, if the spikelets be paired usually one only 
with a long awn ; awn of the upper glume 1-1J lin. long. Lower 
floret barren, equalling the spikelet : valve similar to the upper 
glume, abruptly apiculate, mucronate or with a very short awn, 
9-nerved ; valvule very much reduced or 0. Upper floret oblong, 
acute, lin. long, whitish to brownish, polished ; valve and valvule 
subcoriaceous. Grain oblong, dorsally compressed. Embryo one-
