Information
Shrub or small to medium tree 1.8–15 m. tall, glabrous; bark greyish white, rough warty with old swollen nodes. Leaf blades usually yellow-green when dry, (5)7–18 x 2–7.3 cm., elliptic, oblong, obovate or oblanceolate, ± obtuse to distinctly shortly acuminate at the apex, cuneate at the base, often ± coriaceous; venation closely reticulate; petiole 1–1.7 cm. long; stipules 2.5–5 mm. long, the thicker deltoid part often with a few stiff hairs at its apex. Inflorescences supra-axillary (sometimes only slightly so), compact and subcapitate, several-flowered; peduncles mostly stout, compressed, 2–10 mm. long, thickened apically; bracts and bracteoles triangular, keeled, c. 1.5 mm. long, acuminate, very congested. Calyx tube 0.7–1.5 mm. long; limb 0.9–1.4 mm. long, slightly toothed, the teeth 0.3–0.5 mm. long. Corolla white, sometimes tinged pink in bud, sweetly scented; tube 3.5–5.6 mm. long, densely hairy inside at the throat; lobes 3–5.8 mm. long, oblong-lanceolate to oblong-ovate, hairy inside at least at the base. Anthers with tips just exserted in long-styled flowers, completely exserted and reaching to or nearly to the tips of the corolla lobes in short-styled flowers. Style 7–7.5 mm. long in long-styled flowers, well exserted, 2.6–4 mm. long in short-styled flowers, included; stigma lobes linear-clavate, 1.3–2.5 mm. long. Fruit brown when dry but described as green or black, 5–6(7 in spirit material) mm. long and wide, subglobose or ellipsoid, sessile. Seeds dark brown, shining, bowl-shaped, longest dimension 3.4 mm., shorter dimension 2 mm., the depression deep and rounded.

Riverine, streamside and lake-shore fringing dry evergreen forest also relict mist-forest, often on laterite escarpments and sometimes on termite mounds

Notes
Throughout its range Craterispermum schweinfurthii is distinguished from Craterispermum laurinum (with which it was confused) partly by its sessile fruits but one specimen from Zimbabwe E, Lusitu River, fr. 8.i.1969, Mavi 835 (K; LISC; SRGH) is anomalous in having ± pedicellate fruits—the species is here at the extreme SE limit of its range.
