    Gramineae, E. Launert. Flora Zambesiaca 10:1. 1971

    Spikelets pedicelled, 1-flowered, laterally compressed, gaping at length, falling entire, awned, with an obtuse to acute basal callus; rhachilla disarticulating above the glumes, not produced beyond the floret; floret hermaphrodite, shorter than the glumes (except for the awn).
    Glumes 2, subequal to slightly unequal, 1-nerved, membranous, dorsally rounded below and usually keeled towards the apex, the flanks thinner in texture than the somewhat hardened dorsal surface, with the apex entire to shortly 2-lobed, unawned or awned from between the sinuses or slightly below the apex if entire; awn straight, slender.
    Lemma awned or awnless, shorter than the glumes (excluding the awn), obscurely 5 (very rarely 3-)-nerved, thinly membranous, hyaline, with the apex truncate, the lateral nerves usually excurrent into short mucros; awn straight, slender, usually deciduous, rarely reduced to a mucro or completely absent.
    Palea as long as or slightly shorter than the body of the lemma, 2-nerved, 2-keeled, very thinly membranous, hyaline.
    Lodicules 2, rather small.
    Stamens 3.
    Ovary glabrous; styles distinct, very short; stigmas short, plumose, laterally exserted.
    Caryopsis elliptic to obovate-elliptic in outline, terete in cross-section, free between the slightly indurate lemma and palea; hilum short; embryo 1/4-1/3 the length of the caryopsis.
    Annuals or perennials with slender culms.
    Ligule a scarious membrane.
    Inflorescence a many-flowered panicle, usually condensed, rarely somewhat open.

    Annuals or perennials
    Leaf-blades flat, linear
    Panicle contracted or spike-like
    Spikelets narrowly oblong to oblong, small, falling entire together with the pedicel or part of it; rhachilla not prolonged, eventually disarticulating below the floret. Glumes narrow, subequal, 1-nerved, membranous, rough, keeled above, entire, emarginate or 2-lobed at the tip, with a fine straight awn from the tip or between the lobes; lemma mostly broadly oblong, shorter than the glumes, truncate, thin, finely 5-nerved usually awned from near the apex, with the very fine awn often deciduous; palea as long as the lemma or shorter.
