Levyns, M.R.B., lecturer in Botany at the University of Cape Town from 1916 to 1945. She revised several taxonomically difficult genera, and wrote several influential papers on the biogeography of the Cape Flora. She collected mostly along the arid fringes of the Cape Flora.
Vegetative parts: plants tufted, 0.6-1.5 m tall, basal diameter 0.1-0.3 m, crown diameter 0.3-1 m, compact, without spreading rhizomes or stolons. Fertile culms branching, smooth, olivaceous, 0.6-1.5 m tall, diameter at base 1.4-2 mm, diameter at apex 0.4-0.6 mm. Sheaths closely convoluted, 10-30 mm long, reddish-brown, upper 1/3 in colour and texture abruptly different from the base, and soon decaying, apical margins coriaceous, like the rest of the body, hyaline shoulders absent, apex, excluding the membranous lobes, truncate. Sheath-mucro penicellate, straight and erect, 3-5 mm long, apical 1/3 acute, continuing into a penicellate awn, but the whole portion soon rotting off, leaving a truncate coriaceous base. Males: male inflorescence with 6-10 spikelets or 11-20 spikelets, racemose or paniculate, 20-70 mm long, 7-20 mm wide. Male inflorescence spathes persistent, like the floral bracts, cartilaginous, apical margins often broken. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or ovate, apex rounded, 7-12 mm, 5-7 mm, with 5-12 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts taller than flowers, 3-4 mm long, oblong or ovate, acute, cartilaginous, bract upper margin like body of bract, bract awn minute or absent, much shorter than the spikelet. Male flower 2.5-3 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, oblong, inner tepals shorter than outer tepals. Male outer lateral tepals conduplicate, keel sparsely villous. Anthers 1.5 mm long, exserted from the flowers. Females: female inflorescence racemose, 20-65 mm long, 12-20 mm wide, with 2-5 spikelets. Female spathes like floral bracts, persistent, cartilaginous. Female spikelet sessile, oblong or obtriangular, apex truncate or rounded, 14-22 mm long, with 12-20 flowers, with 0-2 sterile bracts. Female bracts at least twice as long as flowers, 8-11 mm long, oblong, acute, cartilaginous, apical margin like rest of bract, same as body of bract (but apex often broken), awn minute or absent. Female flower 4-5 mm long, without a fleshy pedicel. Female tepals chartaceous, glabrous and smooth, at least as tall as nut, wrapped around it and obscuring the surface, midrib flush with the tepal body, apices rounded, inner whorl longer than outer. Female outer lateral tepals conduplicate, exserted past bracts, 3.3-4 mm long. Female odd outer tepal oblong, 3.3-4 mm long. Female inner tepals oblong, 3.8-5 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, indehiscent. 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, 2.5-3 mm long, 1.2 mm diam., shape in side view oblong, shape in top view triangular in cross section (with the three ribs raised into keels), brown. Elaiosome absent.
