Unless indicated otherwise, the following attributes are implicit throughout the descriptions, except where the characters concerned are inapplicable.
Vegetative form. (5) Erect. (7) Rhizomes fleshy. (8) Basal culm internodes not swollen. (21) Shoots not aromatic. (24) Auricles on the leaf blade. (27) Basal leaf sheaths not swollen, (31) the same colour as the lamina, (33) without readily visible transverse veins. (45) Ligule abaxially glabrous. (53) Leaf blades not stiff, (54) concolourous; (61) flat.
Reproductive organization. (66) Spikelets homomorphic. (71) Plants self compatible, (72) reproducing sexually. (74) Cleistogamous spikelets on the exserted inflorescence.
Inflorescence. (76) Conspicuous vestigial foliar structure subtending the infloresence absent. (82) Inflorescence straight, (86) not deciduous as a unit. (91) Rachides persistent, (92) do not shatter. (101) Primary inflorescence branches do not shatter; (105) of conventional thickness. (114) Spikelets not embedded in the rachis, (115) solitary, (118) subtending foliar structure absent.
Incomplete (`imperfect') spikelets. (169) Lodicules of incomplete florets within incomplete spikelets present.
Hermaphrodite (`perfect') spikelets. (193) Glumes not diverging from the spikelets, (194) free, (195) not ventricose. (207) Lower glume without a keel-wing, (211) base broadly cuneate; (219) awn non-geniculate, (220) not twisted. (227) Upper glume without a keel-wing, (231) base broadly cuneate; (239) awn non-geniculate, (240) awn not twisted. (266) Incomplete lemma veins not connected by transverse veins.
