03F987BEA46F5F446511FC8EE795FDBF.taxon	materials_examined	Type. Bayer 1497 (NBG), South Africa, Northern Cape, Richtersveld Conservancy, west of Eksteensfontein, 2817 CC, Sept. 1978, flowering. Geophyte up to 20 cm tall, bright green, densely but finely hairy. Bulb shallow, up to 6 cm long, teardrop-shaped, distinct elongated upper portion between a third and half of bulb length (apical beak), tunics hard, densely hairy, distinctly longitudinally grooved, light brown, often with contractile root. Rhizome brown, up to 20 cm long, hairy to densely hairy, with light brown alternating scales up to 4 mm long. Above-ground stem up to 4 cm long, green, hairy, with 1 – 2 large (up to 8 mm long) semi-amplexicaul, membranous scales. Leaves 3 – 14, bright green, loosely apically congested, hairy; petioles up to 14 cm long, dilated below basal articulation, hairy; leaflets 3, cuneateobcordate to obcordate, up to 3 × 3.5 cm broad, finely hairy on both sides and along margin, distinctly petiolulate, adaxial side glossy along margin. Peduncles 1 – 7 - flowered, densely hairy, as long as to 2.5 times longer than and as thick as petioles. Bracts 2 – 6, linear, erect, up to 7 mm long, densely hairy, without calli. Pedicels slender, up to 25 mm long. Sepals 5, linear-lanceolate, acute, densely hairy, without calli. Corolla up to 25 mm long, glabrous to sparsely hairy, white, with broad funnel-shaped yellow tube. Petals 5, lobes white, tube yellow, funnel-shaped, densely hairy. Stamens 10, in 3 whorls; 2 whorls per plant, lower whorl 2.5 – 4 mm long, middle whorl c. 5 mm long, longest whorl c. 9 mm long; filaments hairy; anthers oval, yellow. Ovary narrowly ovoid, c. 5 mm long, 5 - loculed, yellow, densely hairy, up to 13 ovules per locule; styles 5, separate, reciprocally herkogamous with two stamen whorls, short-whorled styles curving outwards between filaments, mid- and long-whorled styles erect, densely hairy. Stigmas green, fimbriate. Fruit capsule cylindrical, hairy, twice as long as sepals. Seed endospermous. Diagnostic characters — Geophyte with densely hairy vegetative plant body. Bulb tunics light brown, finely grooved, densely hairy and with apical beak. Corolla lobes white, tube yellow. Both morphological characters and DNA evidence distinguish O. hirsutibulba from all known Oxalis species with umbellate inflorescences. It prefers cool, south-facing cliffs, where it grows in loose soil in cracks. Oxalis hirsutibulba flowers from August to September. Distribution — Only known from three localities in the Northern Cape Province of South Africa. One locality is situated on the southern slopes of the Richtersberg range, another is west of Eksteensfontein, while a third population is known from near Kubus. Additional specimens examined.

03F987BEA46F5F45665EFD96E798F838.taxon	materials_examined	Type. Dreyer, Roets & Oberlander MO 1527 b (STEU), cultivated from Dreyer, Roets & Oberlander MO 1527 a, originally from South Africa, Northern Cape, Richtersveld Conservancy, Tierhoek camping site, 2816 DD, June 2012, flowering. Geophyte with thick succulent stem, up to 40 cm tall, bright apple green, nearly entirely glabrous. Bulb up to 30 cm deep, large, ovoid, 2 – 7.5 cm long, with numerous, dark brown, rumpled and splitting tunics with prominent veins. Rhizome white, up to 25 cm long, glabrous, with large (c. 5 mm long) semi-amplexicaul, light brown, membranous, alternating scales. Arial stem well-developed, thick and succulent, distinctly tapering towards the tip, often branching, bright apple green, glabrous. Leaves alternate along stem or loosely apically congested in groups of 3 – 5, often on short side stems, glabrous; leaf base semi-amplexicaul, winged below articulation with petiole; petioles slender, up to 9 cm long, glabrous; leaflets 3, obcordate to broadly obcordate, adaxially glabrous, abaxially glabrous to very sparsely hairy on veins and base, margin glabrous to very sparsely hairy, petiolules prominent, 1 – 1.5 mm, region below apical incision usually with distinct, variously shaped white to pale green and translucent patch. Peduncles 1 – 6 flowered, longer than the petioles. Bracts 2 – 8, erect, up to 1.5 mm long, glabrous to sparsely hairy, usually with prominent calli. Pedicels slender, 20 mm long, pendulous in bud and in fruit. Sepals 5, lanceolate, acute, without calli, glabrous to very sparsely glandular-pilose, up to 9 × 5 mm. Corolla c. 20 mm long, with broad funnel-shaped yellow tube. Petals 5, claw yellow, ± half the length of the petal, lobes white. Stamens 10, in 3 whorls; 2 whorls per plant, lower whorl c. 3 mm long, middle whorl c. 5.5 mm long, longest whorl c. 9 mm long; filaments sparsely hairy, with mostly simple hairs and a few glandular hairs towards the base, with prominent blunt teeth on longest whorl; anthers oval, yellow. Ovary narrowly ovoid, 4 – 5 mm long, 5 - loculed, glabrous, 5 – 6 ovules per locule; styles 5, separate, hairy with both simple and glandular hairs, reciprocally herkogamous with two stamen whorls, short-whorled styles curving outwards between filaments, mid- and long-whorled styles erect. Stigmas green, fimbriate. Fruit capsule slightly longer than sepals. Seed endospermous. Diagnostic characters — Tall geophyte with thick, branched, succulent, bright apple green stems. Leaflets usually with prominent clear white markings just below the apical incision. The few-flowered inflorescences produce large, white flowers, with pedicels that are often distinctly darker in colour than the peduncle. It is closely related to other branched, umbellate species, such as O. knuthiana, O. petricola and O. rubricallosa and grows in fairly similar habitats. It can immediately be distinguished from these species by the combination of translucent white patches on the leaflets, thick stems, white corollas and ecallose sepals. This species flowers from August to September. The specimens collected near Kubus (Drijhout 2916) seem to lack the white to pale green and translucent patch at the apical incision. Distribution — Only known from southern slopes in the western end of the Richtersveld Conservancy, Northern Cape, where it grows in shady crevices between granite boulders and in rock fields.
