| The meal of pounded seeds of Bauhinia petersiana is eaten. The seeds are also eaten as nuts after roasting and are considered a delicacy in parts of Botswana. Roasted and ground seeds are used as a substitute for coffee. Unripe seeds can also be eaten. The pods are eaten either roasted (Namibia) or boiled (Zambia). Seed oil is extracted in Botswana for local use. In DR Congo the bark fibres are used to make rope and the roots to produce a dye. Bauhinia petersiana is widely browsed by livestock. In Zimbabwe, South Africa and the United States it is grown as an ornamental shrub. In much of its area of distribution the leaves of Bauhinia petersiana are boiled, the steam inhaled and the cooled-down liquid drunk to cure common cough. The Shona people of Zimbabwe take an infusion of the roots to treat dysmenorrhoea and female infertility. In South Africa the pounded leaves mixed with salt are boiled and the warm liquid is sprinkled on wounds to promote healing. A decoction of the macerated roots is drunk as a remedy for diarrhoea. | |||

| Shrub or small tree up to 10 m tall; young branchlets pubescent and with many small orange glands or scales, some branchlets coiled apically, tendril-like. Leaves alternate, simple; stipules 3–5 mm × 1–2 mm, deciduous; petiole 0.5–3 cm long; blade 2–8 cm × 2–10 cm, 2-lobed to one-third to two-thirds down, lobes elliptical to ovate or rounded. Inflorescence an axillary, leaf-opposed or terminal raceme, 1–10-flowered. Flowers bisexual, almost regular, 5-merous; hypanthium (1.5–)2–5.5(–6.5) cm long; sepals linear to linear-lanceolate, 1.5–5 cm long; petals narrowly elliptical to ovate, 2–8.5 cm × 0.5–4 cm, white throughout or sometimes base of midrib pink; fertile stamens (4–)5(–6), slightly unequal in length, staminodes 4–5; ovary superior, slender, hairy, style 2–4 cm long. Fruit a linear-oblong to oblanceolate-oblong pod 10–24 cm × 1.5–5 cm, woody, dehiscent, 5–6-seeded. Seeds 1–3 cm × 0.5–2 cm, deep chestnut-brown to blackish. Bauhinia is a widespread tropical genus with about 250 species. In Bauhinia petersiana 2 subspecies are distinguished. Subsp. petersiana has 2–10-flowered inflorescences, appressed hairs at the lower side of the leaves, and it is distributed in the more eastern and northern parts of the area of the species. Subsp. macrantha (Oliv.) Brummitt & J.H.Ross has 1–3(–4)-flowered inflorescences and curved or spreading hairs at the lower side of the leaves, and it is found from southern Zambia and western Zimbabwe towards the south and west. Bauhinia petersiana does not possess root nodules and relies on soil nitrogen. | |||

| Bauhinia petersiana is found in open grassland, wooded grassland and woodland. In East Africa it is found at altitudes of 150–1850 m. In southern Africa it is found in dry localities, e.g. in the Kalahari with an annual rainfall of about 350 mm only, and it tolerates frost. | |||

| In the Kalahari the seeds of Bauhinia petersiana are harvested from April to July. For use as an ornamental Bauhinia petersiana is propagated by seed, cuttings or layering. The 100-seed weight is about 670 g. | |||

| There are indications that Bauhinia petersiana has disappeared completely from communal grazing land in southern Botswana, possibly as a result of increased grazing pressure. Two accessions from Botswana are stored in the Millenium Seedbank (Ardingly, West Sussex, United Kingdom), a single accession from Zimbabwe is kept by the Desert Legume Programme in the United States. | |||

| Although Bauhinia petersiana has been considered a candidate for cultivation as a food crop for a long time, no attempts have been made to domesticate the species, nor to exploit or even explore its genetic variation. Efforts to conserve the southern populations, in situ or ex situ, are urgently needed to avoid loss of variation. | |||
