Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; not deciduous as a whole (10), or deciduous as a whole (16); exserted (22), or embraced at base by subtending leaf (1). Racemes single; linear (11), or moniliform (4), or lanceolate (7), or ovate (2), or obovate (3); unilateral (1), or bilateral; bearing few fertile spikelets (11), or many spikelets (12); bearing 2-7-20 fertile spikelets on each. Rhachis tough (15), or fragile at the nodes (11); flattened (1/7), or semiterete (6/7); terminating in a spikelet (22), or sterile spikelet (1). Spikelet packing broadside to rhachis. Rhachis internodes indefinite (8), or linear (3), or oblong (10), or cuneate (2); falling with spikelet alongside (5/10), or falling with spikelet above (5/10). Spikelets appressed (6/8), or ascending (2/8); solitary. Fertile spikelets sessile.
Sterile

Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets (1), or 2-3 fertile florets (9), or 4 fertile florets (12), or 5 fertile florets (6), or 6-8 fertile florets (2); with diminished florets at the apex. Spikelets elliptic (5), or oblong (11), or ovate (7), or obovate (1), or cuneate (1); laterally compressed; 5-10.28-15 mm long; falling entire; deciduous with accessory branch structures. Basal sterile spikelets absent (7), or rudimentary (22).
Fertile
Spikelets comprising 1 fertile florets (1), or 2-3 fertile florets (9), or 4 fertile florets (12), or 5 fertile florets (6), or 6-8 fertile florets (2); with diminished florets at the apex. Spikelets elliptic (5), or oblong (11), or ovate (7), or obovate (1), or cuneate (1); laterally compressed; 5-10.28-15 mm long; falling entire; deciduous with accessory branch structures.
