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 m tall, basal diameter 0.05–0.15 m, crown diameter 0.1–0.3 m, compact, without spreading rhizomes or stolons. Fertile culms sparingly branched, round (not compressed), finely warty, green or olivaceous, 0.3–1 m tall, diameter at base 1–3 mm, diameter at apex 0.5–1.3 mm. Sheaths persistent, with no abscission line, closely convoluted, 12–30 mm long, dark brown, apical margins narrowly membranous (this grading into the body), hyaline shoulders membranous margins continuing behind awn, hyaline shoulder 0.1 of sheath body length, apex, excluding the membranous lobes, acuminate or acute (eventually decaying to a truncate apex). Sheath-mucro penicellate, straight and erect, 1–3 mm long, rather dull, the whole apical region eventually decaying leaving a truncate sheath. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, racemose or paniculate, 30–65 mm long, 8–20 mm wide. Male inflorescence spathes persistent, minute or like the floral bracts, coriaceous, generally smaller than bracts, occasionally as big. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical or obovate, apex rounded or obtuse, 8–15 mm, 4–10 mm, with 10–25 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets or as long as the spikelets, terete or angular. Male bracts shorter than flowers or as tall as flowers, 4–6 mm long, oblong or square, obtuse (apiculate), cartilaginous, bract upper margin with honeycombed cells, which eventually decay (very narrow apical fringe), bract awn minute or absent, honey-coloured, black mucro, with 7 nerves. Male flower 4–5 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, oblong, inner tepals shorter than outer tepals or inner and outer tepals the same length. Male outer lateral tepals conduplicate, keel densely villous. Anthers 2–2.5 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence 20–70 mm long, 10–20 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes insignificant or shorter than the spikelets, persistent, coriaceous. Female spikelet sessile or pedicel simple, elliptical or obovate, apex obtuse or acute, 12–23 mm long, with 3–6 flowers, with 2–6 sterile bracts. Female bracts shorter than flowers or as tall as flowers, 6.5–10 mm long, oblong or square, apiculate, cartilaginous, apical margin with honeycombed cells (grading gradually into the body of the bract), darker than body of bract, awn minute or absent. Female flower 5.5–7.5 mm long, without a fleshy pedicel. Female tepals cartilaginous, keels of lateral sepals densely villous or both lateral sepal keels and odd sepal villous, midrib flush with the tepal body, apices acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 5.5–8 mm long. Female odd outer tepal linear or oblong, 5.5–7.5 mm long. Female inner tepals linear or oblong, 5–6.5 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 2 locules, dehiscent. Fruit: seed (1.76–)2.16(–2.36) mm long, (1.16–)1.38(–1.6) mm in diameter, shape in side view elliptical, shape in diameter triangular in cross section, grey, colliculate.
