Morphology Reproductive morphology Inflorescences
Panicle linear, 2–15 cm long, silvery; rhachis with ± rounded ribs and short peduncle-stumps, glabrous or scaberulous; involucre enclosing 1–2 sessile spikelets, without a distinct stipe; bristles glabrous, the longest 7–12 mm

Morphology General Habit
Perennial; caespitose. Culms geniculately ascending; 30-120 cm long; wiry. Lateral branches suffrutescent. Ligule an eciliate membrane; 0.5-1.5 mm long; lacerate. Leaf-blades 3-15 cm long; 2-9 mm wide. Leaf-blade surface glabrous, or pubescent. Leaf-blade apex attenuate; filiform.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; 2-15 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs; smooth, or scaberulous; glabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1-2 in the cluster. Involucre composed of bristles; oblong; 7-12 mm long; base obtuse. Involucral bristles deciduous with the fertile spikelets; numerous; with longest bristle scarcely emergent; 7-12 mm long; terete; flexible; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 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 lanceolate; dorsally compressed; acuminate; 5-5.5 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; shorter than spikelet; thinner than fertile lemma. Lower glume elliptic; 0.1-0.25 length of spikelet; hyaline; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume elliptic, or ovate; 0.33-0.66 length of spikelet; membranous; without keels; 1-3 -veined. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male; with palea. Lemma of lower sterile floret oblong; 1 length of spikelet; membranous; 5-7 -veined; scaberulous; rough above; acuminate. Fertile lemma elliptic; 5-5.5 mm long; membranous; without keel; 5 -veined. Lemma margins flat. Lemma apex acuminate. Palea membranous.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 3; 1.5-2 mm long; anther tip smooth. Styles free to the base.
Distribution
Africa: northeast tropical and east tropical. Asia-temperate: Arabia.
