Branch complement many; in a clump; subtended by a bare patch above the node; with 1 branch dominant. Culm-sheaths deciduous but leaving a persistent girdle; without auricles (2), or auriculate (1). Culm-sheath blade lanceolate, or ovate (2). Leaf-sheath auricles absent (2), or falcate (1). Ligule a ciliolate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; linear (2), or oblong (1), or ovate (1).
    Inflorescences
    Synflorescence bractiferous; fasciculate; with glumaceous subtending bracts; without axillary buds at base of spikelet (1), or with axillary buds at base of spikelet (2). Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets (1), or 6-9 fertile florets (2), or 10-27 fertile florets, or 28-30 fertile florets (2); with a barren rhachilla extension (2), or with diminished florets at the apex. Spikelets linear; subterete; 9-164.6-370 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 3-5 fertile florets (1), or 6-9 fertile florets (2), or 10-27 fertile florets, or 28-30 fertile florets (2); with a barren rhachilla extension (2), or with diminished florets at the apex. Spikelets linear; subterete; 9-164.6-370 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes one the lower absent or obscure (1), or several (2); persistent; shorter than spikelet. Upper glume lanceolate; 0.6-0.7-0.8 length of adjacent fertile lemma; chartaceous; without keels; 5 -veined (1/1). Upper glume surface glabrous (2), or hispidulous (1). Upper glume apex obtuse (1/1).
    Florets
    Fertile lemma lanceolate, or ovate (2); chartaceous; without keel; 3-4 -veined (2), or 5 -veined, or 6 -veined (1). Lemma surface glabrous (1), or puberulous (2). Lemma margins ciliolate. Lemma apex acuminate; muticous (2), or mucronate (1). Palea 1 length of lemma; chartaceous; 1 -veined (1/1); without keels (2), or 2-keeled (1). Palea surface glabrous (1), or pubescent (2). Apical sterile florets resembling fertile though underdeveloped.
