Culm-nodes glabrous. Lateral branches suffrutescent. Bud complement 1. Branch complement one; solitary; as thick as stem. Culm-sheaths 1 length of internode; puberulous; with reflexed hairs. Leaves 2–4 per branch. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades oblong; 6–13 cm long; 17–34 mm wide; mid-green and glaucous; discolorous with last colour beneath. Leaf-blade venation with 12–16 secondary veins. Leaf-blade surface scabrous; pubescent; hairy abaxially. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle.
Panicle open; ovate; 7 cm long; 4 cm wide. Panicle axis pilose.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with diminished florets at the apex. Spikelets linear, or oblong; laterally compressed; 8–12 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 1 mm long; scarious; without keels. Lower glume surface pilose. Lower glume apex acute. Upper glume ovate; 2–7 mm long; scarious; without keels. Upper glume surface pilose. Upper glume apex acute.
FLORETS Fertile lemma ovate; 5–7 mm long; chartaceous; purple; without keel. Lemma apex setaceously attenuate. Palea 4–5 mm long. Apical sterile florets resembling fertile though underdeveloped.
