    Habit
    Inflorescence comprising subdigitate racemes on an axis seldom exceeding their own length.
    Spikelets
    Spikelets 3–7-flowered, subsessile, strongly laterally compressed, disarticulating above the glumes and between the lowermost florets, the lowermost 1–3 florets fertile, the rest sterile and progressively reduced to a tuft of awns; glumes slightly unequal, linear, membranous, 1-nerved, strongly keeled, the inferior shorter than or slightly exceeding the lowermost lemma, the superior exceeding the florets; fertile lemmas thinly membranous, 3-nerved, pilose on the back or only on the margins and keel, acutely 2-lobed at the apex, awned from between the lobes; sterile lemmas usually not lobed, tapering to the awn or reduced to just the awn.
    Fruits
    Caryopsis linear-oblong.

    Habit
    Annual (1), or perennial. Culms erect, or geniculately ascending (1); 20-35-60 cm long. Ligule an eciliate membrane (1), or a fringe of hairs (1), or absent (1). Leaf-blades stiff (1), or firm (1).
    Inflorescences
    Inflorescence composed of racemes. Racemes digitate; unilateral. Rhachis angular. Spikelet packing broadside to rhachis; lax. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1-2 fertile florets (1); with diminished florets at the apex. Spikelets oblong (1), or cuneate (1); laterally compressed; 3-4.375-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Fertile
    Spikelets comprising 1-2 fertile florets (1); with diminished florets at the apex. Spikelets oblong (1), or cuneate (1); laterally compressed; 3-4.375-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Glume
    Glumes persistent; shorter than spikelet (1), or exceeding apex of florets (1); parallel to lemmas (1), or gaping (1). Lower glume linear; 0.75-0.775-0.8 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse (1), or acuminate (1). Upper glume linear (1), or lanceolate (1); 0.8-0.85-0.9 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume apex obtuse (1), or acuminate (1).
    Florets
    Fertile lemma lanceolate; membranous; keeled; 1-2 -veined (1), or 3 -veined. Lemma midvein eciliate (1), or ciliate (1). Lemma surface glabrous (1), or pilose (1). Lemma margins eciliate (1), or ciliate (1). Lemma apex dentate; 2 -fid; incised 0.2 of lemma length; awned; 1 -awned. Principal lemma awn apical (1), or subapical (1); straight (1), or flexuous (1). Apical sterile florets 1-2 in number (1), or 3 in number, or 4-5 in number (1); male (1), or barren; in a clump; rudimentary. Apical sterile lemmas awned.
    Distribution
    Africa.
