    Gramineae, W. D. Clayton, S. M. Phillips And S. A. Renvoize. Flora of Tropical East Africa. 1974

    Habit
    Small tufted annuals or perennials, with slender wiry culms
    Leaves
    Leaf-blades usually narrow, stiff, often convolute; ligule a very short membranous rim
    Inflorescences
    Inflorescence a solitary terminal slender curved 1-sided spike not much wider than the culm, often embraced below by the uppermost leaf-sheath, the spikelets appressed to the tough narrow rhachis (less so in M. caffra)
    Spikelets
    Spikelets 1-flowered (without rhachilla-extension), slightly dorsally compressed, awnless; glumes lanceolate-oblong, boat-shaped, as long as the spikelet or the lower a little shorter, 1-nerved, acute, the lower keeled, the upper rounded on the back; lemma shorter than and enclosed by the glumes, hyaline, ovate to broadly elliptic, ciliate on the nerves, obtuse
    Fruits
    Caryopsis oblong to obovate-oblong.

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

    Inflorescences
    Inflorescence a single raceme (rarely 2) bearing inclined or pectinate spikelets on a semiterete (crescentic in section) rhachis.
    Spikelets
    Spikelets 1-flowered without rhachilla extension or with a second well developed male floret (rarely a third rudiment), subterete or subcylindrical, alternate in 2 rows on a tough axis, disarticulating above the glumes; glumes subequal, 1-nerved, both or only the superior deciduous, firmly membranous to thinly coriaceous, enclosing the floret(s), the inferior keeled, the superior dorsally rounded; lemma thinly membranous, keeled, acute to 2-lobed at the apex, awnless but sometimes mucronulate.
    Fruits
    Caryopsis ellipsoid.

    Gramineae, W. D. Clayton, S. M. Phillips And S. A. Renvoize. Flora of Tropical East Africa. 1974

    Habit
    Tufted perennials with wiry culms
    Leaves
    Leaf-blades linear; ligule represented by a line of hairs
    Inflorescences
    Inflorescence a solitary (rarely paired) terminal 1-sided spike, the spikelets densely packed and often almost at right-angles to the tough narrow rhachis
    Spikelets
    Spikelets 2-flowered (sometimes 3-flowered in R. pseudoharpochloa), lanceolate, slightly dorsally compressed, alternately biseriate, awnless, usually gaping at maturity, the lower floret hermaphrodite, the upper ♂ or sterile and smaller; glumes 2, enclosing the florets, equal or unequal, 1-nerved; lower glume narrowly elliptic, boat-shaped, asymmetric, membranous, obtuse to subacute; upper glume narrowly elliptic, dorsally flattened, chartaceous, obtuse; lemma of lower floret ovate-elliptic, cartilaginous, the lateral nerves ascending to the tip, hairy on keel and nerves
    Fruits
    Caryopsis ellipsoid to broadly trigonous.
