Information
Spreading shrub or small to medium-sized tree up to 9 m high and 0,8 m d.b.h. Bark rough, reticulately fissured, dark brown; branches pen­dulous, branchlets glabrous and reddish brown. Leaves trifoliolate, petiolate; petiole glabrous, semiterete, slightly canaliculate above, (9-)25 (—46) mm long; leaflets sessile, membranous to subcoriaceous, concolorous to slightly discolo-rous, dull green above, slightly paler below, gla­brous, hypostomatous; lamina lanceolate, base cuneate, apex acute to subacute, often mucronu-late, margin entire, serrulate or serrate; venation simple to semicraspedodromous, midrib and secondaries prominent above, only midrib promi­nent below; terminal leaflets (26-)63(—109) x (6-)13(-25) mm, lateral leaflets (12-)39(-72) x (4—)11(—19) mm. Panicles much branched, lax, axillary and terminal, latter up to 120 mm long, forming prominent sprays in autumn. Flowers normal, but ovary oblique, styles de-flexed. Drupe rhombic, discoid, glabrous, shi­ny, light to dark brown, 3,8 x 1,3 to 6,3 x 2,1 mm. Fig. 19.
Habitat
Whereas specimens from the Transvaal lowveld all have prominent serrations, both entire and serrate morphs occur elsewhere, e.g. Bredenkamp 144 (PRE) (serrate) and 355 (PRE) (entire) are both from the Suikerbosrand Nature Reserve near Heidelberg, Transvaal. R. tenuipes R. & A. Fernandes from Zimbabwe may just be a narrower leaved morph of this species.
Use

Range
Occurs on rocky koppies, in bushveld and open savanna in all parts of the Transvaal except the colder south-eastern highveld. It also occurs in the northern and central Orange Free State and just reaches the northern Cape and Botswana. There is an isolated record from the Kaokoveid in north­western Namibia and another doubtful one from the Namib Desert near Walvis Bay. Also occurs in Angola, Mozambique, Zimbabwe and Malawi. Flowering recorded from December to April and in July. Map 23.
