Morphology General Habit
Perennial arising from a short woody rhizome; stems up to 90 cm high, much-branched, wiry or woody; leaves flat or folded; ligule a line of hairs
Morphology Reproductive morphology Inflorescences
Panicle linear to oblong, 2–10 cm long, dense; rhachis with angular ribs below the scars, scaberulous; involucre enclosing 1 sessile spikelet, the base with a very short oblong stipe; bristles glabrous or rarely sparsely ciliate, the longest 4–10 mm, usually in 2 whorls
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets oblong, 3.5–5.5 mm long; lower glume 1/2 the length of the spikelet; upper glume 2/3–3/4 the length of the spikelet; lemmas similar in texture, acute to subulate, the lower male.

Morphology General Habit
Perennial. Rhizomes short; knotty. Culms decumbent; 30-90 cm long; wiry, or woody. Lateral branches ample. Leaf-sheaths glabrous on surface, or pilose; with tubercle-based hairs. Leaf-sheath oral hairs lacking, or bearded. Ligule a fringe of hairs. Leaf-blades flat, or conduplicate; 3-25 cm long; 2-4 mm wide. Leaf-blade surface glabrous, or pilose; sparsely hairy; with tubercle-based hairs.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle scaberulous above. Panicle spiciform; linear, or oblong; 2-10 cm long. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; scaberulous; glabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; oblong; 4-10 mm long; base bluntly stipitate (briefly). Involucral bristles deciduous with the fertile spikelets; numerous; with an outer whorl of thinner bristles; with longest bristle scarcely emergent; 4-10 mm long; terete; flexible; glabrous, or plumose.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; truncate; 3.5-5.5 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; truncate; 3.5-5.5 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.5 length of spikelet; membranous; without keels; 1-3 -veined. Lower glume surface asperulous (above). Lower glume apex acute. Upper glume elliptic; 0.66-0.75 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume surface smooth, or asperulous; rough on veins. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male; with palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 5 -veined; smooth, or scaberulous; rough at apex; acuminate. Fertile lemma elliptic; 3.5-5.5 mm long; membranous; without keel; 5 -veined. Lemma margins flat. Lemma apex acuminate; mucronate. Palea membranous.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 3; 2-2.5 mm long; anther tip smooth. Styles free to the base.
Distribution
Africa: northeast tropical, east tropical, and southern tropical.
