Information
Shrub or small tree 1–8 m. high. Branchlets glabrous, puberulous or ± pubescent. Leaves variable in size, 1–6.9(–10.2) cm. long, 1.2–6.5(–11) cm. wide, bilobed at apex to one-third way down or less, rarely to half way or a little more; lobes rounded; lower surface glabrous, appressed-puberulous, or ± pubescent. Racemes 1–2(–7)-flowered, lateral or terminal, occasionally aggregated. Bracteoles small and inconspicuous, not enfolding the flower-buds. Pedicels 0.7–2.7 cm. long. Flower-buds: upper part (i.e. sepals) ovate in outline, 1.2–2.6 cm. long before anthesis, glabrous or pubescent outside; hypanthium 2–6 mm. long; smooth or slightly sulcate. Petals subcircular to obovate or elliptic, (2.4–)3–5.5 cm. long, (1.5–)2–4.6 cm. wide, not or scarcely clawed, sulphur-yellow, 1–3 of them often (not always) blotched at base with dark brown or purplish. Fertile stamens 10. Stigma 2.5–3 mm. across, rather variable in appearance, terminal, peltate or with one side produced downwards; style gradually enlarged towards the stigma. Pods thinly woody, dehiscent, 6.5–13 cm. long, (1–)1.3–2 cm. wide. Seeds blackish or blackish-brown, ± elliptic, 7–9 mm. long, 5–6 mm. wide; funicle short.

Notes
on synonymy. B. tomentosa L. “var. parvifolia-hirtella Oliv. in Trans. Linn. Soc, ser. 2, 2: 332” (1887) is quoted in L.T.A.: 654 (1930) as if it were a varietal name. I do not think that either it or “var. glabra ”, both given by Oliver, were intended as formal new varieties but as brief descriptive phrases of two variants collected by Johnston on Kilimanjaro. VARIATION. B. tomentosa shows a considerable range of variation—in indumentum from glabrous to strongly pubescent, in leaf-size, in the shape, size and blotching of the petals, in the degree to which the tip of the flower-bud is acuminate and in the shape of the stigma. No clear pattern of variation is apparent, however, and I therefore recognize no named varieties.One character, however, perhaps shows in its variation a link with geography: in East Africa the racemes are generally simple and single, but especially in Mozambique and Rhodesia there is a decided tendency for them to become aggregated into little corymbose panicles with up to 20 or more flowers. Gillman 1128, from Tanganyika, Lindi District, Sudi, 12 Dec. 1942, and Schlieben 5568, also from Lindi District, Lake Lutamba, 30 Oct. 1934, show this tendency. B. tomentosa is frequently cultivated (see, for example, U.O.P.Z.: 143, where it is said that the form grown in Zanzibar has unblotched flowers).
