Characteristics

Evergreen shrub or small tree up to 7 m high (in South Africa up to 3 m high), trunk up to 200 mm diam. Prickles 2-6 mm long, stout, usually sparse on stems, petioles and veins on upper and lower leaf surfaces, flattened towards broad, often pubescent base, straight or slightly recurved, rarely absent. Pubescence on all parts of stellate hairs (sessile or long, multi-seriate-stalked, porrect-stellate with medium or long central cell). Stems grooved and sparsely stellate when old, stem and young parts with ferruginous tomentum. Leaves solitary, usually broadly ovate to elliptical, ±200-300 x ±250-400 mm, rarely entire, margins mostly sinuate to lobed, with 7-13 lobes, sinuses cut one quarter of way to midrib, lobe apices obtuse, acute or acuminate, sinuses rounded, leaf base equal or oblique, truncate or rounded to subcordate; upper surface scabrid and covered with appressed hairs, lower surface densely covered with stellate hairs and nerves sparsely prickly; petiole up to 180 mm long, terete, with (0)3-10 prickles. Inflorescences extra-axillary, branched, dense scorpioid cymes with 30-50 flowers; peduncles 10-25 mm long, variable; pedicels 10-15 mm long, enlarged in fruit up to 5 mm diam. below calyx with marked corky thickening. Calyx densely stellate-pubescent; tube 3-4 mm long; lobes linear or lanceolate, 4-6 mm long, acuminate, in fruit broader and thicker, at first appressed, later somewhat reflexed. Corolla white, 20-50 mm diam., stellate; lobes 10-15 mm long, sparsely stellate-pubescent along midvein inside, densely stellate-pubescent outside, apices acute. Stamens with filaments 1-3 mm long; anthers 7-9 mm long, yellow, slender, erect, not coherent, tapered, dehiscing by small terminal pores and also longitudinally in basal portion of anther. Ovary sometimes tuberculate, ovary and style base sparsely glandular-pubescent; style 9.0-13.5 mm long, glabrous; stigma bluntly 2-lobed, pale green. Fruit globose, 10-15 mm diam., at first green, later yellowish to drab orange-yellow, brown when dry, glabrous, glossy, hard, not particularly fleshy, mucilaginous. Seeds 2-3 mm diam., flat, light brown, shiny, without obvious surface pattern, 100-250 per fruit. Cotyledons 4 x 10 mm, oblong; petioles 5 mm long, first true leaves ovate, scarcely lobed, not prickly until about fourth leaf.

Shrubs 1-1.5 m tall, sparingly armed, densely pubescent overall with rust-colored, short-or long-stalked stellate hairs. Stems angular, with short prickles 2-3 × 1-1.5 mm. Petiole stout, 1-3 cm, sometimes armed; leaf blade broadly ovate or elliptic, 8-20 × 4-14 cm, base obtuse or cordate, often asymmetric, 3-5-lobed to parted; lobes deltate or long deltate, unequal, irregularly sinuate, densely pubescent with rust-colored, stalked stellate hairs, denser abaxially, acute or subobtuse at apex. Inflorescences extra-axillary, many-flowered racemose panicles; peduncle mostly 2-or 3-branched, 5-12 mm, pubescent as on stems. Pedicel stout, 5-10 mm. Calyx cup-shaped, 5-8 mm; lobes deltate-lanceolate, 4-6 mm, acuminate at apex, pubescent as on peduncle. Corolla white, 1.5-1.8 cm; lobes ovate-oblong, 0.8-1.2 cm, acute. Filaments 1-2 mm; anthers oblong, 6-8 mm. Style 8-10 mm. Berry yellow-orange, globose, 8-10 mm in diam. Seeds discoid, 1.5-2 mm in diam. Fl. and fr. throughout the year.
Leaves solitary or geminate, sometimes closely set at ends of branches; petiole 1–11 cm long; lamina rather leathery and rough to touch, 7–47(60) × 4–31(35) cm, broadly ovate to cordate, sometimes elliptic, base obtuse to cordate or truncate, often dimidiate, rarely equal-sided, apex acute to long-acuminate, entire to broadly, deeply and irregularly lobed, the lobes 7–13, rounded to ovate-lanceolate, apically rounded to acuminate, entire to lobulate, the sinuses rounded, hispid above with appressed, short, ± sessile hairs often bearing a long and apically recurved central ray, felty tomentose beneath with mostly brownish hairs, with 5–8 pairs of curved-ascending lateral nerves, sparingly prickly at least on the midrib or unarmed.
Shrub or small tree, up to 3 m high; stellate, red-brown hairs on all parts. Prickles 2-6 mm long, stout, sparse, flattened, straight or ± recurved. Stems grooved. Leaves broadly ovate to elliptic, margins sinuate, 7-13-lobed, base unequal, upper side scabrid and appressed-hairy, underside densely hairy; petioles up to 180 mm long. Inflorescence dense; peduncles 10-25 mm long; pedicels 10-15 mm long. Calyx densely hairy; tube 3-4 mm long; lobes linear-lanceolate, 4-6 mm long, larger in fruit. Corolla stellate, 30-50 mm in diam.; lobes 10-15 mm long. Fruit globose, 10-15 mm in diam., ripening ± yellow, glabrous, glossy, hard. Seeds 100-250, 2-3 mm in diam., flat, ± brown, shiny. Flowering time all year.
Shrub or small tree up to 7.5 m, armed, but flowering branches sometimes unarmed; hairs stellate, ± long stalked to sessile, ± irregular, sometimes with a rather shorter or longer central ray, sometimes bristle-like; prickles reddish-brown to dark purple, 2–8(9) mm long and 1–8 mm wide at the base, laterally compressed and wide towards the base, stout, straight or recurved, subulate upwards, striate, often basally pubescent.
Cymes lateral, extra-axillary or axillary, at first appearing terminal, unbranched, once-forked or more-branched, racemiform, sometimes scorpioid or corymbiform, 4–10 cm long, 4–9 cm across, congested, many-flowered, tomentose or hispid with rusty-red hairs, all flowers hermaphrodite and fertile; peduncle 0.6–3 cm long, stout.
