Leaf-sheaths open for most of their length; with 0.6 of their length closed; 4.5-7.5 cm long; keeled; retrorsely scabrous; puberulous. Leaf-sheath oral hairs lacking, or ciliate. Ligule an eciliate membrane; 1.7-2.2 mm long; 0.3-0.5 mm long on basal shoots; scaberulous on abaxial surface; truncate, or obtuse. Leaf-blades flat, or conduplicate; 5-20 cm long; 2-3 mm wide. Leaf-blade surface scabrous; rough adaxially, or on both sides. Leaf-blade margins scabrous. Leaf-blade apex hooded.
    Inflorescences
    Inflorescence a panicle. Panicle open; pyramidal; 10-18 cm long; 5-10 cm wide. Primary panicle branches spreading; 2-4 -nate; 4-7 cm long; bearing 4-12 fertile spikelets on each lower branch. Panicle axis with lower internodes 2-3.5 cm long. Panicle branches smooth, or scaberulous. Spikelets solitary. Fertile spikelets pedicelled.
