Culms erect; robust; straight, or curved; 110-150 cm long; 2-3 mm diam.; without nodal roots. Culm-internodes terete; smooth, or scaberulous. Culm-nodes constricted; brown; without exudate; glabrous. Lateral branches lacking. Leaves basal and cauline; 3-5 per branch. Leaf-sheaths tight; unthickened at base; open for most of their length; without keel; striately veined; antrorsely scabrous; glabrous on surface. Ligule an eciliate membrane; scarious; white, or brown; entire. Leaf-blade base symmetrical. Leaf-blades erect; straight, or flexuous; linear; linear in section; 20-50 cm long; 7-8 mm wide; flaccid; dark green. Leaf-blade midrib indistinct. Leaf-blade venation distinct; with subepidermal sclerenchyma strands similar in size; with subepidermal sclerenchyma attached to veins above and below; without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface scabrous; rough abaxially; puberulous; sparsely hairy; hairy adaxially. Leaf-blade margins scabrous; glabrous. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle; with 1 peduncles per sheath. Peduncle straight, or flexuous; terete; 20-40 cm long; eglandular; antrorsely scabrous above; glabrous. Panicle open; elliptic, or pyramidal; continuous; loose; straight; 30-40 cm long; 25-40 cm wide. Primary panicle branches ascending; 5 -nate; profusely divided; 10-12 cm long; naked below. Panicle branches flexible; straight, or arcuate; scaberulous. Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels scabrous.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus pilose. Rhachilla internodes scaberulous. Floret callus sparsely hairy.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus pilose. Rhachilla internodes scaberulous. Floret callus sparsely hairy.
    Glume
