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

    Inflorescences
    Inflorescence of digitate or whorled racemes, sometimes subdigitate with additional scattered racemes; racemes with imbricate, biseriate, subsessile spikelets, terminating in an abortive spikelet or rarely a naked point.
    Spikelets
    Spikelets several–many-flowered, oblong with a serrate outline, laterally compressed, the lemmas disarticulating from below upwards, the paleas persistent on the rhachilla, but often the spikelet falling wholly or in part when only a few lemmas have been shed; glumes 1-nerved, keeled, thinly cartilaginous, shorter than the lemmas and falling before or soon after them; lemmas 3-nerved, keeled, cartilaginous, glabrous, the lateral nerves slightly excurrent, entire or 2-toothed and aristulate at the apex.
    Fruits
    Caryopsis elliptic, rugose or smooth, sulcate on the hilar side or not, the pericarp free.
