HABIT Perennial; caespitose; clumped densely. Culms 40–60 cm long. Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 0.5 mm long. Leaf-blades erect; straight, or curled; filiform; conduplicate; 10–30 cm long; 0.75 mm wide; stiff. Leaf-blade venation with continuous uniform subepidermal sclerenchyma layer on the underside. Leaf-blade surface scabrous.
INFLORESCENCE Inflorescence a panicle.
Panicle contracted; linear; 8–20 cm long. Primary panicle branches appressed.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8–10 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume subulate, or linear; 3–6 mm long; 0.7–0.9 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 4–6.5 mm long; 0.7–0.8 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.
FLORETS Fertile lemma elliptic; 5.5–7.5 mm long; coriaceous; without keel; 5 -veined. Lemma surface asperulous. Lemma apex emarginate, or acute; awned; 1 -awned. Principal lemma awn 1–3 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2. Anthers 3. Ovary glabrous, or pubescent on apex.
FRUIT Caryopsis with adherent pericarp; glabrous, or hairy at apex. Hilum linear.
DISTRIBUTION Africa: east tropical.
NOTES Poeae. FTEA.
