Lateral branches dendroid. Branch complement three, or several; in a horizontal line; with subequal branches; thinner than stem. Culm-sheaths persistent; chartaceous; purple; distinctly mottled with last colour; pubescent; hairy at the base; with yellow hairs; glabrous on shoulders. Culm-sheath blade inconspicuous. Leaves cauline; 3-4 per branch. Leaf-sheath oral hairs setose. Ligule a ciliolate membrane. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 6-15 cm long; 8-12 mm wide. Leaf-blade venation with distinct cross veins.

    Synflorescence bractiferous; scanty; with glumaceous subtending bracts; without axillary buds at base of spikelet; without prophylls. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 4-7 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 20-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3-4 mm long; eventually visible between lemmas.
    Fertile
    Spikelets comprising 4-7 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 20-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3-4 mm long; eventually visible between lemmas.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 6-8 mm long; 1 length of upper glume; membranous; without keels; 5 -veined. Lower glume apex acute. Upper glume oblong; 6-8 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex acute.
    Florets
    Fertile lemma oblong; 6-7 mm long; membranous; without keel; 5-7 -veined. Lemma lateral veins with cross-veins. Lemma apex acute. Palea 1 length of lemma; 8 -veined. Apical sterile florets resembling fertile though underdeveloped.
