Bolus, H., established the Bolus Herbarium, collected actively from 1870 onwards, and published on the taxonomy of orchids and ericas. He was the first really prolific plant taxonomist resident in South Africa, and his collections and library were central to the initiation of develop of indigenous plant taxonomy in the Cape.

Vegetative parts: plants tufted, 0.5–1.5 m tall, basal diameter 0.3–1 m, crown diameter 0.5–1 m, compact, without spreading rhizomes or stolons. Fertile culms branching, smooth (Pillans: striate and much pitted.), olivaceous, 0.5–1.5 m tall, diameter at base 2–3 mm, diameter at apex 0.6–1 mm. Sheaths closely convoluted, 15–40 mm long, generally light brown the outer surface; purple at the margins and apex, apical margins narrowly membranous, hyaline shoulders absent, apex, excluding the membranous lobes, acuminate or acute. Sheath-mucro penicellate, straight and erect, 1–10 mm long. Males: male inflorescence with indefinite spikelets, Racemose or paniculate, 20–60 mm long, 4–10 mm wide. Male inflorescence spathes persistent or caducous, taller than spikelets, coriaceous, Very distinct; light brown or grey, paler at the base and purple at margins and apex; awn bony. Male flowers not aggregated into spikelets. Male bracts taller than flowers, 5–8 mm long, linear, acute, lax, chartaceous, bract upper margin like body of bract, bract awn minute or absent. Male flower 3–4 mm long. Male tepals sepals and petals the same rigidity, chartaceous or membranous, linear, inner and outer tepals the same length. Male outer lateral tepals as other tepals, glabrous. Anthers 2–3 mm long, included in the flowers. Pistillode absent. Females: female inflorescence linear or racemose, 20–70 mm long, 4–15 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes longer than the spikelets, obscuring spikelet, persistent or caducous, coriaceous. Female spikelet sessile, elliptical or obovate or obtriangular, apex truncate or rounded or acute, 15–25 mm long, with 1 flowers, with 3–8 sterile bracts. Female bracts taller than flowers, 10–25 mm long, oblong, acuminate, chartaceous or cartilaginous, apical margin like rest of bract, same as body of bract or darker than body of bract, awn less than half as long as the bract body. Female flower 7–9 mm long, with a fleshy pedicel. Female tepals membranous, glabrous and smooth, smaller than nut and not obscuring the nut surface, midrib flush with the tepal body, apices rounded, inner and outer whorls the same length. Female outer lateral tepals like other tepals, 1–2 mm long. Female odd outer tepal square or orbicular, 1–2 mm long. Female inner tepals square or orbicular, 1–2 mm long. Staminodes absent. Styles plumose, white, 2. Style bases free. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a hard woody ovary wall. Perianth presence on fruits persistent, membranous, shorter than nut. Nut apex smooth, without a distinct cap, wall smooth, (5.83–)7.35(–8.67) mm long, (2.5–)3.23(–4.67) mm diam., shape in side view oblong, shape in top view round in cross section, brown. Elaiosome present, 2 mm long (deeply and distinctly fluted), less than half as long as nut.
