Information
Pyrophytic subshrub with caespitose shoots 7.5–50 cm tall (see note) from a horizontal rhizome, usually unbranched unless not burnt back, the stems ± densely short-pubescent. Leaves opposite, alternate, or in whorls of 3–4, ± shiny and darker above, narrowly elliptic, lanceolate, oblanceolate or linear, 4–11 cm long, 1.1–3.1 cm wide, obtuse at the apex, cuneate at the base. Flowers solitary in the axils or at base of plant sometimes in 2–9-flowered inflorescences, sweet-smelling; pedicels 0.6–2 cmlong, pubescent; bracteoles lanceolate to triangular-ovate, 1–2 mm long, persistent. Calyx-tube obconic, 1.5–2 mm long; lobes obovate, round or rounded triangular, 1.5–3 mm diameter, ciliate, glabrous or with few hairs on the faces. Petals white or yellow, oblate-obovate or ± round, 4–7 mm long, 3–5 mm wide, ciliate or not. Stamens ± 50; filaments 3–5 mm long; anthers 0.8–1.2 mm long in male flowers, shorter in female. Receptacle glabrous between the stamens. Style 5 mm long in female flowers with capitate stigma 1 mm long, lacking or much reduced in male flowers. Fruits bright red, purple or black, ellipsoid or subglobose, 0.8–1.5 cm long, edible; pedicels 6 mm long, puberulous. Fig. 14.

Notes
It is not certain quite how tall this plant grows. F. White suggested it never exceeded 50 cm and I think this is probably usually correct but Brenan (T.T.C.L.: 376 (1949)) under E. angolensis mentions 90 cm citing Hornby 64 as the source. Engler (V.E. 3(2): 732 (1921)) gives 6 m for E. stolzii and 2–6 m for E. angolensis but this could be an error for dm, a unit which he uses elsewhere on the page. Certainly no material reaching these heights has been seen. E. marquesii Engl. has been kept up by Boutique and Amshoff. It differs in having more than one flower in the leaf-axils and usually has short racemose inflorescences. F. White (F.Z. 4: 192 (1978)) points out that most specimens with such inflorescences appear to have escaped burning the previous season and occur sporadically throughout most of the range of E. malangensis; his decision to put it into synonymy is followed here but I have seen nothing matching E. marquesii from East Africa. Some plants undoubtedly have nothing but purely male flowers and the species may well be normally dioecious.
