Information
Woody climber up to about 4 m. tall; younger stems more or less softly hairy, longitudinally ribbed and furrowed. Leaves pinnate with 5–7 leaflets or pinnate-ternate; leaflets suborbicular to ovate in outline, shortly acuminate, acute or more rarely subobtuse, cordate to rounded or obtuse at the base, often a longer central lobe with a shorter lateral one on each side but sometimes asymmetric, margins crenate-dentate, from glabrous to densely sericeous-pubescent or tomentose on the lower surface and from glabrous to sparsely appressed-pubescent on the upper surface. Inflorescences generally many-flowered; flowers sweet-scented; pedicels 0.5–3 cm. long; flower-buds spherical to ellipsoid, rounded to acuminate. Sepals 0.8–1.5 cm. long; cream or white. Anthers usually 1.5–2 mm. long. Achenes (including persistent style) up to 4 cm. long.

In woodlands and wooded grassland

Notes
In Southern Rhodesia and Mozambique this species is certainly not separable from the South African C. brachiata Thunb., which is the earliest name available. In the northwest and northeast of the region our material is equally inseparable from an Angolan and East African \"species\" which has been called C. hirsuta Perr. & Guill. in the recent floras of those countries. Although we suspect that much of the material at present referred to C. hirsuta in various parts of tropical Africa will eventually have to be transferred to C. brachiata we have not formally included C. hirsuta in our synonymy because: (a) this latter species needs further collecting from the type locality (Cape Verde Peninsula); and (b) the problem of the \"species\" in East Africa is very complex (see Milne-Redh. & Turrill, F.T.E.A. Ranunc.: 6 (1952)) and does not directly concern us here. In our region the species is much less variable and identification is only difficult in a few cases where there has perhaps been hybridization with C. simensis in the wetter regions, with C. oweniae, more particularly in S. Africa, or with C. viridiflora in Nyasaland and Mozambique.
