14 ft. high, slender, simple, 1-2-noded, terete, glabrous. Leaf- 
sheaths terete, tight, glabrous, or more or less hairy upwards ; ligules 
very short, truncate, membranous, ciliolate ; blades linear, slightly 
rounded at the base or gradually passing into the sheath, tapering 
to a fine point, 2-3 in. by 1-1J lin. or the cauline much reduced, 
pale green, loosely hairy, hairs very fine, spreading from minute 
tubercles ; midrib very fine, primary lateral nerves about 2 on each 
side. Peduncles filiform, 4-9 in. long. Kacemes 2-nate, one sessile, 
the other, or both, with short filiform glabrous or more or less hairy 
bases, dull violet to almost slate-colour, dense, lj to almost 2 in. 
long ; joints linear, slightly and gradually widened upwards, 1J lin. 
long, more or less shortly ciliate on both sides, tips subobliquely 
truncate ; pedicels very similar but more slender. Sessile spikelets 
all heterogamous (or the lowest of the sessile or subsessile raceme 
imperfect), linear-oblong or linear-lanceolate, 3| to slightly over 4 lin. 
long ; callus obtuse, up to 4 lin. long, minutely bearded. Glumes 
subequal, lower thinly chartaceous, unequally 2-denticulate, flat or 
shallowly grooved downwards on the back, glabrous or sparingly hairy, 
more or less unequally keeled, one keel markedly winged upwards and 
often running out into a mucro, the other very narrowly and shortly 
winged, margins sharply indexed, unequally wide ; intracarinal 
nerves prominent, about 5-7, evenly distributed, scaberulous up- 
wards ; upper glume slightly shorter, submembranous, narrowly 
boat-shaped, 3-nerved, ciliate, aristulate from the minute notch ; 
bristle about 2 lin. long. Lower floret reduced to a hyaline oblong 
obtuse 2-nerved ciliate valve, up to 3 lin. long. Upper floret b : 
valve oblong, up to almost 3 lin. long, gibbous below the middle, 
2-fid to beyond the middle with narrow lanceolate ciliate lobes ; 
awn slender, 5-8 lin. long, bent and twisted below the middle ; 
valvule 0. Grain oblong, lin. long, slightly convex on the back. 
Pedicelled spikelet $ or neuter (?), linear, oblong, 2J-3J lin. long, 
glabrous Or sparingly hairy ; lower glume thinly chartaceous to 
membranous, unequally 2-dentate with a short bristle from between 
the teeth, intracarinal nerves 3 or more ; upper glume somewhat 
shorter, subhyaline, very acute, mucronulate, ciliate, 3-nerved ; 
valves of both florets delicately hyaline, ciliolate, 2- and 1 -nerved 
respectively or almost nerveless. — Durand & Schinz, Consp. FI. Afr.
