Morphology Reproductive morphology Inflorescences

Companion sterile spikelet glumes similar in width; indurate; 5.5-10 mm long. Companion sterile spikelet lemmas 1; 4-6 mm long; muticous, or 1-awned. Spikelets comprising 1 fertile florets; without rhachilla extension, or with a barren rhachilla extension. Spikelets lanceolate; dorsally compressed; 6-9 mm long; falling entire; deciduous with accessory branch structures.
Sterile
Companion sterile spikelets well-developed; male; lanceolate; dorsally compressed; 5.5-10 mm long; as long as fertile, or longer than fertile; deciduous with the fertile. Companion sterile spikelet glumes similar in width; indurate; 5.5-10 mm long. Companion sterile spikelet lemmas 1; 4-6 mm long; muticous, or 1-awned.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension, or with a barren rhachilla extension. Spikelets lanceolate; dorsally compressed; 6-9 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes collateral; similar; shorter than spikelet, or reaching apex of florets; gaping. Lower glume lanceolate; 5.5-8 mm long; 1 length of upper glume; coriaceous. Lower glume surface scabrous. Lower glume apex setaceously attenuate. Upper glume lanceolate; 5.5-8 mm long; coriaceous. Upper glume surface scabrous. Upper glume apex setaceously attenuate.
