Vegetative parts: plants tufted or mat-Forming or tangled or several much-branched culms from base, 0.3-1 m tall (generally below 0.5 m tall, except in the Sandveld), basal diameter 0.1-1 m, crown diameter 0.1-1 m, with stolons. Fertile culms branching, smooth or finely rugulose, olivaceous, 0.2-1 m tall, diameter at base 1-2.2 mm, diameter at apex 0.3-0.7 mm. Sheaths loosely convoluted or flat and standing free from culm, 5-25 mm long, pale brown, apical margins coriaceous, like the rest of the body, hyaline shoulders absent, apex, excluding the membranous lobes, obtuse or rounded. Sheath-mucro penicellate or awl- or needleshaped, straight and erect, 1-4 mm long.<br>Males: male inflorescence with 1 spikelet or 2-5 spikelets or 6-10 spikelets or 11-20 spikelets, racemose or paniculate, 15-70 mm long, 3-20 mm wide. Male inflorescence spathes persistent, shorter than spikelets, cartilaginous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or ovate, apex rounded, 5-10 mm, 4-7 mm, with 7-20 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts taller than flowers, 2.5-3.5 mm long, oblong or ovate, obtuse or acute, cartilaginous, bract upper margin like body of bract, bract awn minute or absent. Male flower 1.5-2 mm long. Male tepals sepals and petals the same rigidity, chartaceous, linear or oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, keel sparsely villous. Anthers 1.2-1.5 mm long, exserted from the flowers.<br>Females: female inflorescence paniculate or racemose, 6-80 mm long, 2-15 mm wide, with 1 spikelet or 2-5 spikelets or 6-10 spikelets. Female spathes shorter than the spikelets or as long as the spikelets or longer than the spikelets, not obscuring spikelet, persistent, coriaceous. Female spikelet sessile or pedicel simple or pedicel sparsely branching, elliptical, apex acute, 6-15 mm long, with 3-10 flowers, with 0-2 sterile bracts. Female bracts taller than flowers, 5-7 mm long, oblong, apiculate, cartilaginous, apical margin like rest of bract, same as body of bract, awn minute or absent or less than half as long as the bract body. Female flower 2.3-3.5 mm long, without a fleshy pedicel. Female tepals chartaceous, keels of lateral sepals densely villous, at least as tall as nut, wrapped around it and obscuring the surface, midrib flush with the tepal body, apices rounded, inner and outer whorls the same length or inner whorl shorter than outer. Female outer lateral tepals conduplicate, 2.3-3.5 mm long. Female odd outer tepal oblong or obovate, 2.1-3.5 mm long. Female inner tepals obovate, 2-3.5 mm long. Staminodes present (but almost invisibly small). Styles feathery, pink, 3. Style bases free. Ovary with 1 locule, indehiscent.<br>Fruit: indehiscent fruits with a softer ovary wall. Perianth presence on fruits persistent, papery to leathery, not winged. Nut apex smooth, without a distinct cap, wall smooth, 2-2.5 mm long, 0.9-1.2 mm diam., shape in side view obovate, shape in top view triangular in cross section, tan. Elaiosome absent.
