Leaf-blade surface scabrous; rough adaxially; glabrous, or puberulous; hairy on both sides. Leaf-blade margins scabrous. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; bilateral; (6-)8-17(-20) cm long. Rhachis flattened. Spikelet packing broadside to rhachis; crowded; with subequal internodes, or lowest internode elongated. Spikelets in pairs, or in threes. Fertile spikelets sessile; 2-3(-4) in the cluster.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 12-18 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 12-18 mm long; breaking up at maturity; disarticulating below each fertile floret.
