- Morphology Reproductive morphology Inflorescences
- Inflorescence a panicle. Panicle open; ovate; loose; 3-24 cm long; 2-15 cm wide. Primary panicle branches spreading. 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 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes definite; pubescent. Floret callus pilose.
