Information
Scrambling or erect shrub or small tree 1–5(9) m tall, often deciduous, the branches usually slender; bark grey-black; branchlets grey to purple-brown, with or without lenticels, glabrous or pubescent, or setulose on young parts.Leaves 1.8–11 × 0.7–5 cm, oblong-elliptic to ovate or lanceolate, acuminate at the apex with the tip ± rounded, broadly cuneate to rounded at the base, glabrous save for barbellate domatia, or sparsely to fairly densely appressed pilose or setulose, particularly on the midrib, usually distinctly thin; petiole 2–7 mm long; stipules ± connate at the base, 1.5–3 mm long, with triangular-truncate bases, scarious but sometimes becoming woody, ± villous inside, with a subulate appendage 2–8 mm long or rarely lacking.Cymes umbel-like, 2–8-flowered, often produced together with young leaves; peduncle 0.5–4 mm long, or ± obsolete; pedicels 2–10(15) mm long; bracteoles 1–2 mm long, connate to form a scarious involucre.Calyx tube 1–1.5 mm long, the limb 0.3 mm long, truncate or obscurely toothed, scarious.Corolla rounded to sub-apiculate at the apex in bud; creamy, yellow or greenish-white; tube 2.5–4 mm long, with a ring of deflexed hairs within; lobes 1.8–3 mm long, triangular or oblong, subapiculate.Style 4–4.5 mm long.Stigma described as yellow below, green in middle and blue on top, coroniform, 5-lobed.Ovary (4)5–locular.Fruit black, 6–9 mm in diameter, subglobose, with (2)4–5 pyrenes; pedicels 7–12 (15) mm long.Pyrenes usually pitted.
Habitat
Deciduous forest and woodlands, and in riverine thicket and forest. Woodland types include: Brachystegia–Julbernardia, Cryptosepalum–Copaifera, Maerua–Pteleopsis–Cassipourea–Entandrophragma caudatum, and also Baikaea–Fagara–Friesodielsia–Baphia on Kalahari Sand, and Afzelia–Garcinia–Bridelia–Albizia on maritime sand dunes, sometimes in rocky places and on termite mounds

Notes
As interpreted here Rytigynia umbellulata is very variable, but further work is needed to confirm my circumscription. Robyns recognised many species which are not separable, but possibly I have gone too far and have not recognised enough. The lowland Mozambique material is always glabrous and varies considerably in the peduncle length – if this is to be treated separately then Baillon's epithet lagoensis would be the earliest name. Some material from Zambia varies from glabrous to quite densely pubescent and corresponds with welwitschii. The pitting of the pyrenes varies considerably and needs investigation in the field. The specimen de Koning et al. 9759 (BR; K; LMU) [Mozambique, N: Nampula, Mossuril, Serra de Mesa, fr. 19.ii.1984] differs in its slightly larger fruits with a more obvious persistent calyx limb, longer more slender pedicels, much longer peduncles and more finely reticulate leaves. Patel & Seyani 1330 (K; BR; MAL) [Malawi, S: Mulanje, Mpinda, Chingoa Hill, fl. 6.xi.1983] has yellowish-brown, almost shiny, shoots, the epidermis peeling to reveal a pale undersurface (stem described as cream-coloured in life). Both may prove to be distinct taxa when more material is available.
