Leaf-blades filiform; conduplicate; 5-15 cm long; 0.6-1 mm wide; mid-green. Leaf-blade surface scabrous; rough adaxially. Leaf-blade margins smooth. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; loose; 4-9 cm long; 1-5 cm wide. Primary panicle branches ascending. Panicle branches scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 3.5-6 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes definite; pubescent. Floret callus pilose.
Fertile
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 3.5-6 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes definite; pubescent. Floret callus pilose.
Morphology Reproductive morphology Inflorescences Bracts Glume
