similar, 1J-2J lin. long, ciliate along the outer edge (rarely almost 
glabrous), hairs increasing upwards, the uppermost up to 1 lin. long. 
Sessile spikelet subulate-lanceolate to linear, 2-dentate, including 
the shortly bearded callus 3-4 lin. long, glabrous. Glumes sub- 
equal ; lower subcoriaceous, reddish or dark brown, rounded and 
smooth on the back to beyond the middle, then thinner, pale, flat 
and distinctly 2-keeled, with the keels scaberulous, intracarinal 
nerves 2-4, very obscure ; upper glume slightly shorter, firmly 
membranous, rather thin above the middle, subulate, acuminate, 
1-nerved, keel scaberulous, margins ciliolate. Lower floret reduced 
to a linear-oblong acute valve, up to 2J lin. long, sub-2-nerved, 
hyaline, ciliolate. Upper floret $ : valve 2 lin. long, divided to 
three-quarters of its length, base obovate, segments lanceolate, 
acute, ciliolate ; awn 7-8 lin. long, kneed at the middle, column 
dark, bristle whitish ; valvule 0 or a microscopic scale. Stamens 3 ; 
anthers \ lin. long. Grain cylindric, over 1 lin. long, scutellum less 
than half the length. Pedicelled spikelet $ (or neuter and more or 
less reduced), narrowly lanceolate, acuminate, about 2 lin. long, 
glabrous ; lower glume flat, 2-keeled, minutely 2-dentate, with a 
short bristle, minutely scaberulous upwards, intracarinal nerves 5-7 ; 
upper glume subhyaline, sub-3-nerved, eciliate. Valve of lower 
floret as in the sessile spikelet. Valve of upper floret entire, linear-
