    Habit
    Perennial. Rhizomes absent (4), or short (1). Culms erect (4/4); 30-80-200 cm long. Culm-internodes terete (1/1). Lateral branches lacking (4/4). Ligule a fringe of hairs. Leaf-blades filiform (1), or linear (4); stiff (1), or firm (4).
    Inflorescences
    Inflorescence a panicle. Panicle open (3), or contracted (2). Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 15-25.4-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent (4), or pilose (1); obtuse (1), or pungent (3), or 2-toothed (1).
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 15-25.4-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent (4), or pilose (1); obtuse (1), or pungent (3), or 2-toothed (1).
    Glume
    Glumes persistent; exceeding apex of florets; thinner than fertile lemma. Lower glume linear (1), or lanceolate; 1-1.17-1.5 length of upper glume; hyaline (1), or membranous (1), or chartaceous (3); without keels; 3 -veined (3), or 4 -veined (1), or 5 -veined (3). Lower glume surface smooth (3), or asperulous (1), or scabrous (1). Lower glume apex acute (1), or acuminate (2), or setaceously attenuate (2). Upper glume linear (1), or lanceolate; 1.2-1.45-2 length of adjacent fertile lemma; membranous (2), or chartaceous (3); without keels; 3 -veined. Upper glume surface smooth (4), or scabrous (1). Upper glume apex obtuse (1), or acute (1), or acuminate (1), or setaceously attenuate (2).
    Florets
    Fertile lemma linear (4), or lanceolate (1); subterete; chartaceous (2), or coriaceous (3); of similar consistency on margins (4), or much thinner on margins (1); without keel; 3 -veined. Lemma surface smooth (3), or scaberulous (2); without grooves (4), or with a median groove (1). Lemma margins involute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn straight (3), or curved (1), or 3-branched (1). Lateral lemma awns subequal to principal (4), or shorter than principal (1). Palea 0.1-0.145-0.15 length of lemma.
    Flowers
    Lodicules 2. Anthers 3. Ovary glabrous (4/4).
    Fruits
    Caryopsis with adherent pericarp; linear; dorsally compressed (4/4). Embryo 0.2-0.205-0.25 length of caryopsis. Hilum linear; 1 length of caryopsis.
    Distribution
    Africa.

    Spikelets
    Spikelets 1-flowered, pedicelled, in terminal laxly contracted panicles.
    Flowers
    Rhachilla disarticulating above the glumes.
    Florets
    Floret hermaphrodite, exceeding the glumes.
    Glume
    Glumes persistent, narrow, acute or acuminate, 3-5-nerved, awned or awnless.
    Lemma
    Lemma narrow, subcylindric, somewhat dorsally compressed, slightly tapering upwards, with involute margins, 3-nerved, becoming indurated at maturity, without an articulation, bearing at the base an acute, densely but shortly barbate callus, awned from the apex of the lemma or from the apex of a thick twisted column (if present); awns 3, glabrous or scabrid, rigid, spirally contorted at the base when mature.
    Palea
    Palea very small, scale-like, indurated at the base, 2-nerved, glabrous.
    Lodicules
    Lodicules 2, slightly longer than the palea.
    Stamens
    Stamens 3.
    Pistil
    Ovary glabrous; styles free; stigmas 2, plumose.
    Fruits
    Caryopsis dorso-ventrally compressed, deeply grooved, tightly enclosed by the lemma, free, with a linear hilum; embryo 1/5 - 1/4 the length of the caryopsis.
    Habit
    Perennial, densely caespitose grasses with erect, usually simple culms and long linear leaves; ligule a rim of long or short cilia.
    Inflorescences
    Panicles erect, narrow, more or less densely contracted, usually interrupted.
