Information
Shrub or small tree (1) 1·5–9 m. high, occasionally taller (up to 18 m.), evergreen, glabrous; branches rather stout, somewhat flattened and with raised lines decurrent from the petiole-bases when young, soon terete, pale grey or grey-brown, almost smooth; bark vertically fissured, dark grey or grey-brown, sometimes pink-tinged. Leaves petiolate; lamina (1·5) 2–12·5 (15) × (0·6) 1–4·5 (5) cm., varying from oblanceolate or rhombic (rarely obovate) to elliptic (rarely sub-circular), rounded or shortly acuminate towards the apex but always ± shallowly emarginate at the tip, narrowly to broadly cuneate (rarely rounded or truncate) at the base, coriaceous, bright to dark green or bluish-green and shining above, paler green or pale reddish-brown below, with midrib and ± loosely reticulate venation prominent on both sides; petiole 1·5–6 mm. long, rather slender, grooved above; stipules completely united, 1–2 mm. long, broadly triangular, acute, with entire membranous margin, persistent. Flowers solitary or in fascicles of 2–8 in the leaf-axils, usually borne in clusters on stem regions with short internodes; pedicels 5–14 mm. long, rather slender, angular. Sepals c. 1 mm. long, triangular, acute, united for about 1/4 of their length. Petals white, c. 4 mm. long, oblong, rounded at the apex, shortly unguiculate; ligule 1–1·5 mm. long, shortly fimbriate, inserted 1/4 of the length above the base. Short-styled flowers: stamens equal, 4 mm. long; stamen-cup equal to the sepals, usually with 10-denticulate margin; ovary c. 1·5 mm. long, slightly longer than stamen-cup, obovoid; styles 3–1·5 mm. long, free. Long-styled flowers: stamens unequal, the antisepalous 1·75 mm. and antipetalous 3·5 mm. long; stamen-cup as above; ovary as above; styles 3, 3–3·5 mm. long, free. Drupe 8–12 mm. long, bright red, ampullaceous at first but occasionally becoming broadly ellipsoid.

Notes
The leaves of E. emarginatum are very variable in shape and size. Narrow-leaved and small-leaved forms have been distinguished as var. angustifolium and var. caffrum respectively; but although these extreme forms appear distinct, they are connected with the typical ones by continuous series of intermediates and cannot therefore be given separate taxonomic rank.E. fischeri Engl., an East African species, is found in the south of Tanganyika and may well occur also in our area. It can be easily distinguished from E. emarginatum by the longer anthers (1–1·25 mm. as against 0·5 mm.) and the cylindric or triquetrous fruits.
