branches often very few, representing slender narrow racemes up to 
2 in. long, all hairy and often silky- villous at the thickened base ; 
pedicels filiform with thickened tips, 2-1 lin. long, hairy, hairs up to 
1 lin. long. Spikelets oblong, not quite 2J lin. long, straw-coloured 
to chestnut-brown when young, at length dark, slightly glossy, 
densely greyish-pubescent, at length glabrescent on the back. Glumes 
thinly coriaceous, lower minutely truncate, finely 7-nerved, callus 
obscure, very shortly bearded ; upper glume very similar. Valve 
of lower floret oblong, over \ lin. long, hyaline, ciliolate, 2-nerved, 
of upper oblong, shortly 2-lobed, over 1 lin. long, ciliolate, finely 
3-nerved below ; awn 1-1J in. long, twisted up to the middle, the 
twisted part often flexuous or curved ; valvule shorter than the 
lodicules, ciliolate. Lodicules ciliolate. Anthers 1J lin. long. 
Grain obovate-oblong, truncate, 1 lin. long, brown ; embryo-mark 
obscure, about half the length of the grain. — Hack, in DC. Monogr.

2. C. macrantha, Stapf. Annual. Culms up to over 7 ft. high, 
simple, rooting from the lowest nodes, rather slender, glabrous. 
Leaf-sheaths terete, the lowest loose, the others tight, more or less 
hirsute from tubercles or more often glabrous, slightly striate ; 
ligules up to over J lin. long, firmly scarious, rounded ; blades linear, 
tapering to a long fine point, gradually narrowed to the base, which 
is hardly narrower than the mouth of the sheath, up to 1 ft. long and 
almost 4 lin. wide, flat, appressedly pubescent on both sides, the 
larger hairs springing from minute' tubercles, midrib somewhat 
stout downwards, rounded on the back, whitish, lateral nerves 3-4 
on each side, fine, margins spinulously ciliate. Panicle linear, up 
to 6 in. by J-f in., erect ; rhachis angular upwards, ciliate on the 
angles ; branches solitary or 2-nate, simple, suberect, up to 2 in. 
long, angular, ciliate ; pedicels 2-J lin. long, thickened at the tips, 
ciliate, upper cilia up to \ lin. long, fulvous. Spikelets oblong, 3 lin. 
long, dark brown, somewhat glossy, densely and brightly fulvous- 
pubescent. Glumes coriaceous, lower minutely truncate, finely 
7-9-nerved, the nerves only visible on the inner side ; callus obscure, 
very shortly bearded; upper very similar. Valve of lower floret 
oblong, acuminate, almost 2J lin. long, membranous, hyaline up- 
wards, ciliolate, 2-nerved ; of upper floret oblong, shortly 2-lobed, 
over 1| lin. long, ciliolate, finely 3-nerved below ; awn up to 1 in.
