Origin and Habitat: South Africa. Northern Cape (Steinkopf and Aggeneys to Wallekraal and Loeriesfontein) and northern Bushmanland. Widespread (Extent of occurrence 25 429 km²).
Habitat and Ecology: Desert, Nama Karoo, Succulent Karoo. Brunsvigia namaquanaSN|34315]]SN|34315]] is a deciduous bulbous herb that is quite common in rocky quartzitic slopes, quartzite inselbergs and granite outcrops. B. namaquana in its natural habitat flowers erratically any time from November to May (early summer to late autumn), usually in response to brief, sporadic rain showers. The population trend is stable and not in danger of extinction.

Description: Brunsvigia namaquana is one of the choicest of South Africa's smaller amaryllids (2.5-10 cm tall when flowering) found in quartzite and granite outcrops in Namaqualand. It has zygomorphic flowers and a very unusual foliage with leaves covered in golden bristles, two characteristics not common among species of Brunsvigia. In mature plants the leaves are flat on the ground. The flowers are pink with a yellow-green throat in a small head. It flowers in response to autumn rain (or watering in the greenhouse) and later produces the characteristic prostrate hairy leaves. This took 10 years to flower from seed.
Bulb: Ovoid, 20–35 long, 15–28 mm in diameter, sometimes with a neck up to 50 long, inner tunics fleshy to papery, outer tunics brittle, tan-coloured.
Leaves: The bulb puts out 3-4, occasionally 2, leaves absent or emerging at flowering in autumn. The blades usually lay flat or nearly so on the ground are strap-shaped to narrowly elliptical 14-100 mm long, (7–)10–12(–18 or more) mm wide, pale green, often flaccid and have pustules bearing conspicuous, pale- to straw-coloured bristles 2.5–5.5 mm long, either concentrated on the longitudinal veins or densely scattered over the upper surface. The bristles are straight and pliable. The lower surface is smooth. The leaf margin is thin-textured, micropapillate and without bristles. The presence of bristles is unusual in Brunsvigia and is rare in Amaryllidaceae.
Inflorescence: 4–8(–11)-flowered loosely spreading at anthesis. Scape erect, 15–60 mm long, pinkish brown. Spathe valves 2, 13–30 mm long, membranous, pink. Bracteoles filiform. Pedicels 10–30(–55) mm long, pinkish brown.
Flowers: The flowers are zygomorphic, pale to dark pink, with darker pink veins, yellow-gree to cream-coloured throat with declinate to spreading stamens of variable length. Tube up to 1.5 mm long. Tepals recurved and widely separated from others, narrowly oblong–lanceolate, 11–24 mm long, 2.5–4.5 mm wide. Stamens of different lengths, about as long as or up to 8 mm longer than tepals. Filaments pink with pale green at base coalescent basally for up to 2 mm long. Anthers, maroon, pollen cream-coloured. Ovary 3-angled, 2–4 mm in diameter, brownish pink to greenish pink. Style slender, white to pale pink, up to 21–32 mm long, exerted well beyond stamens. Stigma trifid.
Fruits (cacpsules): Small (8–15 mm long, 7–13 mm in diameter), heart-shaped, thin-walled splitting open readily down the septa for half or more of their length.
Seeds: Subglobose, fleshy, about 3 mm in diameter.
Similar species: B. namaquana is similar to Brunsvigia radula. According to Müller-Doblies and Müller-Doblies (1994), B. namaquana differs from B. radula in leaf number per season, (2)3 or 4 vs. 2 or (4), leaf width, (7–)10–12(–18) vs. (24–)36–45 mm, stamen orientation, declinate vs. spreading, and stamen length, 1.5 times longer than the tepals vs. slightly longer than the tepals. In addition, lateral appendages at the base of the filaments, when present, are narrowly winged in B. namaquana.
