Information
Shrub or small tree up to 8 (10·5) m. high, with bark smooth, grey to bluish-grey, flaking in thin sheets to reveal cream to yellow-brown or pale grey patches; branches slender or rather stout, spreading widely, creamy white at first, becoming dark grey. Leaves petiolate; lamina 3·5–18·5 × 1·3–5·7 cm., elliptic to oblong or oblanceolate (rarely obovate), acute or obtuse to rounded (often apiculate) at the apex, with margin entire or densely appressed-spinulose-serrulate towards the apex, narrowly cuneate or attenuate to rounded (rarely truncate to subcordate) at the base, subcoriaceous, with numerous (c. 20–30) lateral nerves and densely reticulate tertiary venation more prominent above than below; petiole 2–6 (8) mm. long, triangular in section or ± flattened, stout, often ± swollen; stipules oblanceolate or elliptic to subulate, 1–2 cm. long. Flowers (20) 25-c. 50, in a simple (rarely compound towards the base) terminal erect or pendulous raceme (1·5) 2·5–10·5 (15) cm. long in fruit; pedicels 1·2–2·7 cm. in fruit, articulated at the base or in the lower 1/3. Sepals 5–9 mm. long in flower, elliptic to obovate, rounded, becoming red or pink, 10–19 mm. long, convex and eventually reflexed in fruit. Petals golden to pale yellow, 9–11 (13) × 4–6·5 mm., obovate to oblanceolate. Stamens with anthers 1–2 mm. long, about 1/2 as long as the filaments, straight, dehiscing by apical pores. Carpels 7 (rarely 8), with styles free at the apex. Drupelets reniform, inserted centrally, 11–14 × 7–10 mm.: embryo curved.

Notes
O. pulchra is recorded from Nyasaland by Burtt Davy and Hoyle, Pardy and Palgrave, but I have seen no specimens from that region and these records may be based on misidentifications.O. pulchra is very variable in leaf-size and shape and several “species”have been split off from it. Only one of these variations appears to merit taxonomic recognition, on account of its correlation with an inflorescence character and its geographical distribution. Since the correlation is incomplete, however, it can most conveniently be treated as a subspecies.
