Characteristics

Tree or shrub 3–27 m tall with smooth grey or greybrown bark; branches purplish brown, somewhat angular, usually glabrous or rarely puberulous when young; bark not peeling, lenticellate; slash pink to dull red.. Leaves mostly rather thin, oblanceolate, obovate or elliptic to oblong, (1.5–)5–13 cm long, (0.7–)1.2–4.3 cm wide, usually acute to narrowly acutely acuminate, but can be more obtuse in small-leaved forms in south, cuneate to ± rounded at the base, margin densely curved-serrulate; lateral veins 20–25, usually ± at right angles to mid-rib together with the dense tertiary venation prominent above; petiole 1–3(–3.5) mm long, ± slender and often appearing longer since leaves can be borne on very short slender spur shoots, but with a small bud at junction with petiole.. Flowers 5–20 in racemiform inflorescences with rhachis up to 2 cm long, less often subumbellate; pedicels 1.3–4 cm long, articulated at base (first flower) or within 3 mm of it, glabrous or rarely puberulous.. Sepals oblong-elliptic, unequal, 6–9 mm long, 3–5 mm wide, becoming deep red in fruit, 9–18 mm long, (3.5–)6–8 mm wide.. Petals pale to bright yellow, obovate, 8–12 mm long, 3–6 mm wide.. Anthers 1–2 mm long, ± 1/2 length of the filaments, dehiscing by longitudinal slits.. Carpels 5(–6) with styles usually completely united; stigma subglobose or 5–6-lobed.. Drupelets black, ellipsoid-cylindric, less often ovoid or subglobose, 8–14 mm long, 5–9 mm wide, inserted at or near base.
More
Understorey trees up to about 8 m tall or shrubs with red wood and rough ridged, grey or brown bark which does not flake; branches spreading; young branchlets with scattered raised lenticels, glabrous or puberulous. Leaves tardily deciduous, immature at time of flowering, radiating in a horizontal plane from the tips of young shoots in a somewhat digitate pattern; blade narrowly elliptic, 5-10 cm long, 1.5-2.5 cm broad, apex attenuate-acuminate, base cuneate, regularly and closely serrulate, stiffly membranous, lateral veins curving upwards from midrib; stipules intrapetiolar, fused. Flowers usually in (2)6-10-flowered racemes, on short lateral spurs below new leafy shoots (tropical forms with many-flowered elongate racemes); pedicels thin, up to 3 cm in fruit, articulated above base, glabrous or puberulous. Sepals narrowly elliptic, c. 9 mm long, obtuse, ivory at anthesis, up to 1.5 cm long, red, pink, purple or green and spreading in fruit, somewhat crinkled when dried. Petals obovate, about 1 cm long, clawed, pale to bright yellow, caducous. Stamens c. 40, with filaments 3 mm long; anthers 1.5 mm long, dehiscing by longitudinal slits. Carpels 5(-6), erect; style with a swollen, lobed stigma. Drupelets basally to swollen torus.
Understorey tree, 0.5-12.0 m high; wood red; bark rough ridged, grey or brown, young branches with raised lenticels. Leaves immature at flowering, shortly petiolate, narrowly elliptic, base cuneate, apex attenuate-acuminate, margins regularly serrate; veins distinctly reticulate below; stipules intrapetiolar, fused. Pedicels slender, up to 30 mm in fruit. Sepals narrowly elliptic, ivory-coloured at anthesis, red, pink, purple or green in fruit. Petals obovate, pale to bright yellow, fugaceous. Stamens ± 40; filaments 3 mm long, dehiscing by longitudinal slits. Carpels 5(6), stigmas swollen, lobed. Flowering time Oct., Nov.
Leaves petiolate; lamina (3) 5–12·2 × (1·2) 1·5–3·9 (4·3) cm., oblanceolate or obovate to elliptic or oblong, acute or acutely to obtusely acuminate at the apex, with margin densely curved-serrulate, cuneate at the base (more rarely narrowed to a rounded base), herbaceous to chartaceous, with numerous widely spreading lateral nerves (usually at almost 90° to the midrib) and densely reticulate tertiary venation prominent above (with main laterals rather more prominent than subsidiaries) and smooth below; petiole 1–3 (3·5) mm. long, rather slender, grooved above.
Tree 3–20 m. high (to 27 m. in East Africa), with bark smooth, grey or grey-brown; branches ± quadrangular, purplish-brown and glabrous or very rarely papillose-puberulous at first, becoming striate or slightly ridged and glabrous, with bark not exfoliating, with numerous small lenticels often somewhat elongated laterally.
Flowers (5) 7–14 (20) in a ± elongated raceme, simple or very rarely branched at the base, with rhachis up to 20 mm. long, rarely pseudumbellate; pedicels 1·3–3·5 (4·1) cm. long in fruit, articulated in the lower 1/6 or at the base, glabrous or rarely papillose-puberulous.
Understorey tree or shrub, up to 8 m high. Leaves borne in a horizontal plane, appearing almost digitate on ends of branchlets, acute basally, attenuate-acuminate distally. Flowers in 6-10-flowered racemes. Flowers pale to bright yellow.
Drupelets (8) 9–12 (14) × (5) 6–7 (9) mm., ± flattened-cylindric, rarely ovoid or subglobose, inserted at or near the base; embryo straight.
Sepals 6–9 mm. long in flower, oblong-elliptic, rounded, becoming pinkish-red to deep-red, 9–15 (18) mm. long, flat and spreading in fruit.
Carpels 5 (6), with styles completely united (or very rarely slightly free at the apex); stigma 5 (6)-lobed or subglobose.
Stamens with anthers (1) 1·5–2 mm. long, c. 1/2 as long as the filaments, straight, dehiscing by longitudinal slits.
Petals pale to bright yellow, (8) 10–12 × 3–6 mm., obovate, narrowed to a short claw.
