Information
Tufted perennial, the basal sheaths soon falling away; culms wiry, 30–120 cm. high, arising from a dense leafy tussock or rambling from a knotty rootstock, without stilt roots. Leaf-blades linear, 5–30 cm. long, 1.5–8(–10) mm. wide, smooth, glaucous, hard, the base attenuate to rounded; ligule membranous, 1–4 mm. long. False panicle linear to oblong, 5–20(–30) cm. long; racemes 10–15 mm. long, the lowermost internode and pedicel connate and swollen. Sessile spikelet narrowly elliptic, 3–4.5 mm. long; lower glume firmly membranous, narrowly winged, shallowly concave on the back with a V-shaped median groove towards the base, without oil streaks and intercarinal nerves or these obscure and confined to the tip; upper lemma bifid to the middle, the awn 6–15 mm. long with a distinct column. Pedicelled spikelet narrowly lanceolate, 3–5 mm. long, with clear closely spaced nerves. Fig. 179.

Notes
The tussocky form prevalent in Africa has commonly been separated as C. excavatus. A close relative, C. nervatus (Hochst.) Chiov., occurs in Ethiopia and the Sudan. It is an annual or short-lived perennial, in which the lower glume of the sessile spikelet is thinly membranous, with two clear intercarinal nerves flanked by brown oil streaks.
