Descriptions

Morphology General Habit
Perennial; caespitose. Culms erect; 30-60 cm long. Ligule a ciliate membrane. Leaf-blade base tapering to the midrib. Leaf-blades 20-30 cm long; 4 mm wide; stiff. Leaf-blade midrib widened.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle with branches tipped by a raceme. Peduncle hirsute above. Panicle open; linear; 10-20 cm long. Primary panicle branches appressed. Panicle axis villous. Rhachis fragile at the nodes; subterete; pilose on surface. Rhachis internodes linear. Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster; subequal. Pedicels linear; ciliate.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base truncate. Spikelet callus hairs purple; 2-3 mm long; 0.5 length of spikelet.
