Lateral branches dendroid; spreading. Branch complement many. Culm-sheaths 15-23 cm long; 1 times as long as wide; pubescent; with appressed hairs; with tawny hairs; truncate at apex, or convex at apex; auriculate; ciliate on shoulders. Culm-sheath blade triangular; cordate; erect. Leaves cauline. Leaf-sheaths striately veined; glabrous on surface. Leaf-sheath oral hairs setose; pale. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2 cm long; petiole pubescent. Leaf-blades linear, or oblong; 15-25 cm long; 17-37 mm wide. Leaf-blade midrib evident. Leaf-blade venation with 12-20 secondary veins. Leaf-blade surface puberulous; hairy abaxially. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; lax; with spathaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets linear; subterete; 25-75 mm long; 5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; clavate; eventually visible between lemmas; pilose; hairy at tip.
Fertile
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets linear; subterete; 25-75 mm long; 5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; clavate; eventually visible between lemmas; pilose; hairy at tip.
