Plants tufted perennials. Culms 30–100 cm tall, unbranched above the base, erect, infrequently decumbent or sprawling, usually flattened, bases 1–2 mm wide; nodes glabrous; internodes 4–14 cm long, soft, hollow. Leaves: sheaths longer or shorter than the internodes, round or slightly flattened, glabrous on the sides and margins; collars green or tan; ligules 0.5–1 mm long, membranous, truncate, erose or lacerate; blades 7–32 cm long, 2.5–5.5 mm wide, linear, flat but becoming folded to loosely involute, often disarticulating at base, midrib prominent; lower surfaces glabrous to scabridulous; upper surfaces scabridulous, also with scattered, delicate, straight hairs near the base, the hairs 3−5 mm long. Panicles 3.5−19 cm long, 1.0–3.0 cm wide, exserted at maturity, composed of central rachises with 2−8 racemosely arranged branches; rachises often somewhat zig-zaged from each spikelet insertion to the next, steeply ascending to erect, rigid, scabrous; branches 2–7 cm long, alternate rachies. Spikelets 5–10 mm long, subsessile, usually imbricate, with 7–12-florets; calluses glabrous; glumes subequal,2−3.8 mm long,1-veined, membranous, lanceolate to narrowly ovate, , acute to obtuse, midveins dark green, scabrous; rachilla internodees cartilaginous, expanded distally; lemmas 2.5–4.7 mm long, ovate, obtuse to subacute, unawned, pale green with dark green veins, often tinged with dark or olive-green , usually 3-veined, membranous above, margins cartilaginous and involute proximally, dorsal surfaces appressed pilose proximally, glabrous distally, the hairs clavicorniculate; paleas 1/2−2/3 as long as the lemmas, ovate, obtuse. keels longitudinally bowed-out, ciliolate, dorsal surfaces glabrous or with appressed clavicorniculate hairs on the lower half. Anthers 0.2–0.3 mm long, yellowish. Lodicules about 0.2 mm long. Caryopses 1.2–1.5 mm long, 0.7−0.9 mm wide.
Disakisoerna yemeicum grows from Ethiopia south to South Africa and east to the southern portion of the Arabian Peninsula in Acacia and miombo woodlands on dry, shall, often stoney soils, often in disurbed habitats, at 250-2100 m. In the past, it has been included in Eragrostis, Eleusine, Leptochloa, and Cypholepis.
