    Inflorescences
    Inflorescence a contracted panicle.
    Spikelets
    Spikelets 2–6-flowered; glumes subequal, as long as the spikelet; floret callus pungent; lemmas dorsally rounded, 9-nerved, with lines of short hairs between the nerves, each terminating above in a tuft of longer hairs, deeply 2-lobed at the apex, with a straight or geniculate awn in the sinus; palea shorter than the body of the lemma, ciliolate along the wingless keels.

    Habit
    Perennial. Rhizomes absent (1), or short (2), or elongated (1). Culms erect (1), or geniculately ascending (2), or decumbent (3); 3-61-120 cm long. Ligule a ciliate membrane (2), or a fringe of hairs (2). Leaf-blades deciduous at the ligule; stiff. Leaf-blade margins cartilaginous (1/1). Leaf-blade apex pungent.
    Inflorescences
    Inflorescence a panicle; exserted (3), or embraced at base by subtending leaf (2). Panicle contracted. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 fertile florets (3), or 3-4 fertile florets (2), or 5-6 fertile florets (1); with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 7-11.62-24 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes elongated between glumes. Floret callus evident; pubescent; pungent.
    Fertile
    Spikelets comprising 2 fertile florets (3), or 3-4 fertile florets (2), or 5-6 fertile florets (1); with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 7-11.62-24 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes elongated between glumes. Floret callus evident; pubescent; pungent.
    Glume
    Glumes persistent; shorter than spikelet (1), or reaching apex of florets (2), or exceeding apex of florets (2). Lower glume lanceolate (1), or elliptic (3); 1 length of upper glume; chartaceous; without keels; 7 -veined, or 8-9 -veined (3), or 10-11 -veined (1). Lower glume surface smooth (1), or asperulous (3); glabrous, or pubescent (2). Lower glume apex acute (3), or acuminate (1). Upper glume lanceolate; 2 length of adjacent fertile lemma; chartaceous; without keels; 5-6 -veined (1), or 7 -veined, or 8-9 -veined (3), or 10-11 -veined (1). Upper glume surface smooth (1), or asperulous (3); glabrous, or pubescent (2). Upper glume apex acute (3), or acuminate (1).
    Florets
    Fertile lemma oblong; chartaceous; much thinner above; without keel; 9 -veined. Lemma lateral veins without ribs (2), or ribbed (2). Lemma surface pubescent; hairy between veins; with a transverse row of hair tufts. Lemma margins eciliate (2), or ciliolate (2). Lemma apex lobed; 2 -fid; incised 0.4-0.5063-0.6 of lemma length; acuminate; awned; 1 -awned. Principal lemma awn from a sinus; straight (3), or geniculate (3). Palea 0.75 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; fleshy. Anthers 3.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid (1/1).
    Distribution
    Africa, or Temperate Asia (2), or Tropical Asia (1).

    Spikelets
    Spikelets 2–6-flowered (the uppermost floret usually reduced to a small scale), lanceolate, enclosed by the glumes; glumes chartaceous, acute, separated by an internode 0.5–1 mm. long, the lower 7–11-nerved, the upper 5–9-nerved; lemmas rounded on the back, membranous becoming coriaceous, 7–11-nerved, densely pubescent between the nerves and with a transverse row of 6–8 tufts of long hairs on a level with the base of the awn, deeply divided into 2 lanceolate, hyaline, glabrous lobes, awned from between the lobes; awn straight or geniculate (and then with a loosely twisted column); paleas shorter than the lemmas; callus 1–1.8 mm. long, obliquely pungent.
