    Habit
    Perennial. Stolons absent (1), or present (1). Culms decumbent; 30-53.75-90 cm long. Leaf-sheaths tubular for much of their length (1/1). Leaf-sheath auricles erect. Ligule an eciliate membrane. Leaf-blades linear, or lanceolate (1). Leaf-blade midrib conspicuous (1/1).
    Inflorescences
    Inflorescence a panicle. Panicle contracted. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
    Spikelets
    Spikelets comprising 2 fertile florets (1), or 3-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 15-20.25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent; pungent.
    Fertile
    Spikelets comprising 2 fertile florets (1), or 3-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 15-20.25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent; pungent.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume linear (1), or lanceolate (1); 0.6-0.725-0.8 length of upper glume; membranous; without keels; 3 -veined. Lower glume apex acute (1), or acuminate (1). Upper glume linear (1), or lanceolate (1); 0.8-1.05-1.2 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex acute (1), or acuminate (1).
    Florets
    Fertile lemma lanceolate, or oblong (1); chartaceous; without keel; 7 -veined, or 8-9 -veined (1). Lemma lateral veins prominent (1/1). Lemma apex entire (1), or dentate; 2 -fid; awned; 1 -awned. Principal lemma awn dorsal; coiled. Palea surface glabrous (1), or pubescent (1). Apical sterile florets resembling fertile though underdeveloped (1), or distinct from fertile (1); 1-2 in number (1/1); in a clump (1/1); linear (1/1). Apical sterile lemmas awned (1/1).
    Flowers
    Lodicules 2; fleshy; truncate. Anthers 3. Stigmas 2 (1/1). Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; linear (1/1), or oblong (1/1). Embryo 0.1 length of caryopsis. Hilum punctiform (1/1).
    Distribution
    Africa (1), or Tropical Asia.

    Spikelets
    Spikelets pedicelled, (1)2-6-flowered, laterally compressed, linear-lanceolate to narrowly oblong in outline, long awned; florets (the lowermost spikelet often 1-flowered) loosely arranged, the lower 2-4 usually bisexual, the following either male or greatly reduced; callus relatively long, slender, linear, densely whitish-hairy; rhachilla glabrous, disarticulating above the glumes and between the florets, usually produced beyond the uppermost floret.
    Glume
    Glumes 2, subequal, persistent, apex subacute to acute, membranous, with hyaline margins; the inferior slightly smaller than the superior, 3-nerved; the superior 5-nerved, often with transverse veinlets.
    Lemma
    Lemmas much exceeding the glumes, distinctly 7-nerved, expanded lanceolate to lanceolate-elliptic or narrowly elliptic, herbaceous at first, later chartaceous, apex shortly bilobed or more rarely entire, awned from the back beneath the sinus of the lobes; awn rather long, increasingly slender towards the apex, scaberulous, twisted, becoming entangled with the awns from the other florets.
    Palea
    Paleas shorter than the lemmas, 2-keeled, linear, with thin hyaline margins.
    Lodicules
    Lodicules 2, minute, cuneate-truncate, fleshy, glabrous.
    Stamens
    Stamens 3; filaments broadened towards the base; anthers linear-oblong.
    Pistil
    Ovary glabrous, oblong in outline; styles distinct; stigmas plumose, laterally exserted.
    Fruits
    Caryopsis linear-oblong in outline, almost terete, dorsally with a long terminal groove, the apex crowned with the persistent base of the style; embryo small; hilum minute, basal.
    Habit
    Perennial grasses with flaccid leaves.
    Ligules
    Ligule a short membrane.
    Inflorescences
    Inflorescence an open somewhat secund panicle.

    Spikelets
    Spikelets 2–6-flowered, the upper ± reduced; callus linear, 2 mm. long, densely clad in short stiff bristles; glumes unequal, herbaceous-membranous, 3–5-nerved, rounded on the back; lemmas much exceeding the glumes, herbaceous, becoming hardened, prominently 7-nerved, rounded on the back, shortly 2-toothed or almost entire, awned from the back just below the tip; awn flexuous, very fine, becoming coiled and entangled with the awns from other lemmas.
