Morphology General Habit
Perennial; caespitose; clumped densely. Culms geniculately ascending; 25-50 cm long; 1.8-2 mm diam.; 6-9 -noded; with 0.5 of their length below uppermost node. Culm-internodes terete; striate; distally glabrous. Culm-nodes glabrous. Lateral branches lacking. Leaf-sheaths with 0.33 of their length closed; longer than adjacent culm internode; pilose; outer margin hairy. Ligule a fringe of hairs; 4 mm long. Leaf-blades involute; 1.5-2 cm long; 4 mm wide. Leaf-blade surface glabrous; hairless except near base. Leaf-blade apex abruptly acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; linear, or lanceolate; 11-15 cm long; 1-1.5 cm wide. Primary panicle branches appressed; 1 -nate; 1-2.5 cm long. Panicle axis glabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 4-12 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 lanceolate; laterally compressed; 4-12 mm long; 1.5-1.8 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume lanceolate; 1.4 mm long; 0.9 length of upper glume; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.6 mm long; 0.9 length of adjacent fertile lemma; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 1.8 mm long; membranous; grey; keeled; 3 -veined. Lemma midvein scaberulous. Lemma lateral veins prominent. Lemma apex acuminate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 0.3-0.4 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ellipsoid; 0.7-0.8 mm long; light brown. Embryo 0.5-0.66 length of caryopsis. Hilum elliptic.
Distribution
Africa: Macaronesia.
