Gramineae, T. Cope. Flora Zambesiaca 10:2. 1999

Morphology Reproductive morphology Inflorescences
Inflorescence of digitate racemes; racemes secund, disarticulating at maturity from the top of the culm, the spikelets biseriate, imbricate, subsessile, the uppermost abortive and the raceme terminating in a naked pointed extension of the rhachis.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets several-flowered, laterally compressed, disarticulating above the glumes but not between the florets; glumes 1-nerved, keeled, membranous, subequal, shorter than the lemmas, persistent, the inferior sharply acute, the superior with a stout spreading awn usually arising from just below the broadly rounded emarginate apex; lemmas 3-nerved, the lateral nerves shorter than the body and obscure, keeled, membranous, glabrous, the apex entire, acute to shortly awned; palea keels sometimes winged.
Morphology Reproductive morphology Fruits
Caryopsis angular, ornamental, with a free hyaline pericarp which ruptures to release the seed.

Morphology General Habit
Tufted or stoloniferous annuals or perennials
Morphology Leaves
Leaf-blades linear, flat or loosely folded; ligule membranous, truncate, often ciliolate
Morphology Reproductive morphology Inflorescences
Inflorescence digitate, composed of several linear to narrowly oblong secund spikes which disarticulate at maturity from the top of the culm (very tardily in some species); uppermost spikelets abortive, the spike terminating in a pointed extension of the flattened rhachis

Spikelets several-flowered, elliptic to ovate, laterally compressed, biseriate, closely overlapping, disarticulating above the glumes but not between the florets; glumes 1-nerved, keeled, subequal, shorter than the lemmas, persistent, the lower sharply acute, the upper with a stout spreading awn usually arising just below the broadly rounded emarginate tip; lemmas 3-nerved, with the lateral nerves shorter than the lemmas and obscure, keeled, membranous, glabrous, the tip entire, acute to shortly awned; palea subequalling the lemma, keels sometimes winged
Morphology Reproductive morphology Fruits
Grain angular, ornamented, enclosed within a free hyaline pericarp which ruptures to release the grain.
