Descriptions

Morphology General Habit
Perennial; caespitose; clumped densely. Culms erect; 8-12 cm long. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs. Leaf-blades involute; 40 cm long; 1.5-2.5 mm wide. Leaf-blade surface scabrous; rough adaxially. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle 2-4 cm long. Panicle open; ovate; 4-5 cm long. Primary panicle branches 1 -nate; 2.5 cm long. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 1-10 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 4-10 mm long; 1.5-1.8 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas.
Fertile
Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 4-10 mm long; 1.5-1.8 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate; 0.6-1 mm long; 0.5 length of upper glume; hyaline; without keels. Lower glume apex acute. Upper glume lanceolate; 1.2 mm long; 0.7-0.8 length of adjacent fertile lemma; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 1.5-1.7 mm long; membranous; keeled; 3 -veined. Lemma surface glabrous. Lemma apex acute. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Distribution
Africa: northeast tropical.
