appressedly hairy at the base, otherwise glabrous, intracarinal 
nerves none or very obscure ; upper glume membranous, lanceo- 
late, acute, 2 lin. long, very minutely hairy, faintly 3-nerved. Lower 
floret 1 j lin. long : valve lanceolate, acute or subacute, hyaline, 
glabrous. Upper floret about 1 lin. long : valve lanceolate-oblong, 
obscurely 3-dentate, 1 -nerved ; valvule 0. Anthers 1 lin. long. 
Grain linear-oblong, dorsally compressed, almost flat on the back, 
1 1 lin. long, scutellum elliptic, less than half the length of the grain, 
hilum basal, large, punctiform. Pedicelled spikelet ovate-lanceo- 
late, 2 lin. long. Glumes equal, glabrous, with fine bristles 1J-2 
lin. long ; lower spreading more or less horizontally, more or less 
twisted, with a narrowly winged, minutely ciliolate keel on one side, 
apart from the submarginal nerves on the keelless flat side almost 
nerveless ; upper glume boat-shaped, glabrous, 1-nerved. Florets

Culms from a few inches to over 1 ft. high, erect, tufted, simple 
below, fastigiately branched upwards, the branches flowering and 
spreading in 2’s and 3’s from the upper internodes, slender, terete, 
glabrous or with a few hairs close below the nodes, 4-5-noded ; inter- 
nodes mostly exserted. Leaf-sheaths glabrous, smooth, the lower 
terete and tight, the upper wide, spathaceous, bladeless or almost 
so, at last turning red ; ligules short, membranous, densely cilio- 
late ; blades linear, tapering to a fine point, 2-6 in. long by 1 lin. 
wide, rather thin, glabrous below, more or less pubescent above, 
the base often almost villous, and beset there with scattered long 
near tubercle-based hairs along the margins, smooth apart from the 
rough upper margins, with 1 lateral nerve on each side, prominent 
below. Racemes 1J-2J in. long, erect, straight, embraced below 
by the spathe, very rarely slightly exserted, pale straw-coloured or 
more or less tinged with purple or reddish. Rhachis fragile ; joints 
subclavate, slightly curved, about 2 lin. long, disarticulating 
obliquely, with a short 2-toothed appendage, back' rounded, minutely 
pubescent or almost glabrous, with a short beard on each side of 
the base and another up to 3 lin. long on the outer side near the top, 
inner face pubescent all along ; pedicels similar but shorter, densely 
ciliate along the outer angle, without a terminal tuft or an appen- 
dage. Sessile spikelet, including the short obconical densely bearded 
callus but excluding the beak, 2J-3 lin. long, lanceolate-oblong. 
Glumes unequal ; lower firmly chartaceous, produced into a straight
