2 \ lin. long, with dense hairs \ lin. long from the short callus. Glumes

4-noded, silky-hairy below the panicle. Leaf-sheaths tight, firm, 
terete, smooth, glabrous except towards the mouth where they are 
frequently ciliate along the margin and often tomentose near the 
junction with the blade, pallid, the basal long-persistent ; ligules 
very short and rounded, scarious, hairy on the back ; blades terete, 
quill-like, channelled towards the base, over 3 ft. long, 1 lin. in diam., 
pale green, smooth, tomentose above the ligule, otherwise glabrous. 
Panicle narrow, erect, tawny-villous, up to 20 in. long, and up to 
4 in. wide, rarely wider ; rhachis smooth, hairy below, terete, or 
angular above, primary branches up to 8 in. long, filiform, more or 
less flexuous, the lowest distinctly peduncled, the others loosely 
divided near the base. Racemes finely filiform, flexuous, tough ; 
joints subcapillary, 2-3 lin. long or in lax specimens much longer, 
finely scaberulous, more or less hairy or glabrous ; pedicels paired, 
like the joints with discoid tips, one very much longer than the other. 
Spikelets lanceolate to oblong, up to 2 lin. long, tawny, with dense 
whitish hairs up to 1 lin. long from the short callus. Glumes of 
equal length, membranous, the lower narrowly oblong, minutely 
truncate or 2-toothed, 2-keeled, with 1 or 2 intracarinal nerves and 
1 extracarinal nerve on each side, with hairs up to 1| lin. long from 
the lower part of the back ; upper glume lanceolate, subacute, 
3-nerved, with hairs like the lower. Valve of the lower floret lanceo- 
late, subacute, slightly shorter than the glumes, hyaline, 1-nerved, 
long-ciliate and pubescent above ; of the upper narrowly lanceolate- 
linear, long-ciliate, pubescent on the back, 1J lin. long, delicately 
hyaline, with a fine flexuous awn 2J-3J lin. long. Valvule very
