Vegetative parts: plants mat-Forming, 0.3–1 m tall, basal diameter 0.1–2 m, crown diameter 0.2–2 m, with stolons. Fertile culms sparingly branched or branching, round (not compressed) or compressed near apex, smooth or finely warty, olivaceous, 0.3–1 m tall, diameter at base 0.8–2 mm, diameter at apex 0.4–0.8 mm. Sheaths closely convoluted, 8–20 mm long, olivaceous, like the culms, apical margins narrowly membranous (reddish brown on Mlanje, hyaline in Zaire), hyaline shoulders membranous margins continuing behind awn (narrow), hyaline shoulder 0.05 of sheath body length, apex, excluding the membranous lobes, acute (from Zaire) or rounded (Mlanje). Sheath-mucro penicellate, straight and erect, 0.5–2 mm long (short on Mlanje, long in Zaire). Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, racemose, 15–40 mm long, 5–10 mm wide. Male inflorescence spathes persistent or caducous, shorter than spikelets or taller than spikelets, coriaceous (like the sterile sheaths). Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or ovate, apex obtuse, 5–10 mm, 4–8 mm, with 4–6 flowers, pedicels absent ie spikelets sessile. Male bracts as tall as flowers or taller than flowers, 4–8 mm long, ovate, acute or acuminate, cartilaginous, bract upper margin like body of bract, bract awn minute or absent. Male flower 3–5 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals chartaceous, oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, glabrous or keel sparsely villous. Anthers 1.5–3 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence racemose, 15–30 mm long, 5–10 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes shorter than the spikelets, persistent, coriaceous (like the sterile sheaths). Female spikelet sessile, oblong or ovate or obovate, apex obtuse, 6–10 mm long, with 1–8 flowers, with 1 sterile bracts (prophyll is sterile). Female bracts as tall as flowers or taller than flowers, 4–9 mm long, oblong or ovate, acute or acuminate, cartilaginous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 3–3.5 mm long, without a fleshy pedicel. Female tepals cartilaginous, glabrous and smooth or keels of lateral sepals sparsely villous, midrib flush with the tepal body, apices acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 3–5 mm long. Female odd outer tepal oblong, 3–5 mm long. Female inner tepals oblong, 3–5 mm long. Staminodes present. Styles feathery, 3. Style bases free. Ovary with 2 locules, dehiscent.
