Descriptions

Gramineae, T. Cope. Flora Zambesiaca 10:2. 1999

Morphology General Habit
Inflorescence a contracted panicle.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 2–5-flowered; glumes unequal to subequal, shorter than the spikelet; floret callus short, obtuse; lemmas keeled, 3–5(7)-nerved, glabrous or pubescent on the margins, bilobed at the apex, with a short straight awn in the sinus, sometimes the lobes also awned; palea almost as long as the lemma, the keels glabrous, wingless.

Morphology General Habit
Perennial. Culms erect; 10-41.66-70 cm long. Ligule a fringe of hairs. Leaf-blades filiform; stiff (1), or firm (2). Leaf-blade apex muticous (1), or pungent (2).
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-4 fertile florets (1), or 5-6 fertile florets (2); without rhachilla extension (1), or with diminished florets at the apex. Spikelets ovate; laterally compressed; 5-7.216-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded.
Fertile
Spikelets comprising 2-4 fertile florets (1), or 5-6 fertile florets (2); without rhachilla extension (1), or with diminished florets at the apex. Spikelets ovate; laterally compressed; 5-7.216-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 0.75-0.8-0.9 length of upper glume; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute (1), or acuminate; muticous (1), or awned (2). Upper glume lanceolate (1), or ovate (2); 0.5-0.8583-1.3 length of adjacent fertile lemma; 1-keeled; 1 -veined, or 2-3 -veined (2). Upper glume apex acuminate; muticous (1), or awned (2); 1 -awned (2/2).
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; membranous; keeled; 3 -veined (2/2), or 4-5 -veined (1/2). Lemma midvein eciliate (2), or ciliate (1). Lemma margins eciliate (2), or ciliate (1). Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus. Palea 1 length of lemma; 2 -veined (2/2). Palea apex muticous (1), or with excurrent keel veins (2). Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2 (2/2); fleshy (2/2).
