Plants usually perennial, annual in a few populations, occasionally stoloniferous. Culms 30–200 cm long, solid, decumbent or clambering to erect; nodes glabrous. Leaves cauline; sheaths half as long to slightly longer than internodes, glabrous or margins ciliate distally; ligules membranous, 0.5–1.5 mm long, ciliate or fimbriate; blades linear. Inflorescences panicles composed of several to numerous unilateral spikelike branches, racemosely or subdigitately attached to a central axis, terminal and exserted at maturity or cleistogamous in lower leaf sheaths; branches slightly reflexed to scending or steeply erect. Spikelets sessile to subsessile, dorsally rounded to flattened, typically overlapping, disarticulation above the glumes; florets 4−13; glumes 2, 1-veined or occasionally with 2 additional veins near base, mucronate or emucronate; lemmas sometimes cartilaginous towards the base, 3-veined, rarely with 2 additional veins near base, macrohairs acute, obtuse, or clavicorniculate; paleas often somewhat cartilaginous towards base; lodicules 2, flabellate; stamens 3. Caryopses dorsally flattened, broadly concave on the hilar surface; pericarp weakly adnate to endosperm. 2n = 40, 60, 80.

Disakisperma includes 4 species, 2 native to the Old World (Disakisperma obtusiflora and Disakisperma yemenicum) and 2 to the New World (Disakisperma dubium and Disakisperma eleusine).

Plants perennial, tufted, 100-200 cm tall. Leaves: ligules membranous; blades linear, ciliate or fimbriate. Inflorescences panicles of spikelike branches attached to an elongated central axis, more closely spaced distally. Spikelets with 7-12 florets, laterally compressed; glumes equal or unequal, exceeded by the florets; lemmas 3-veined, variously pubescent. Grains concavo-convex, pericarp free.

Disakisperma includes 4 species, 2 native to the Old World (Disakisperma obtusiflora and Disakisperma yemenicum) and 2 to the New World (Disakisperma dubium and Disakisperma eleusine). There are two species in Somaliland and Somalia.
