Characteristics

A weak, straggly, lax, much-branched shrub or small tree up to 3 m. tall.. Branches arching.. Twigs greyish brown, sparingly lenticellate.. Young shoots and petioles evenly adpressed pubescent or puberulous.. Petioles 1–5 mm. long, rarely with glands at the top; leaf-blade narrowly ovate-lanceolate to elliptic-lanceolate, (2–)4–8(–10) cm. long, (0.5–)1–2(–3.5) cm. wide, acutely to obtusely long-acuminate, usually narrowly cuneate, fairly shallowly and somewhat irregularly crenate-serrate, firmly membranous, lateral nerves 4–5 pairs, ascending, not or weakly looped, scarcely prominent above, slightly so beneath, sparingly pubescent above and beneath, more evenly so along the midrib and main nerves, drying green, never purplish.. Stipules minute, conical-cylindric, not aculeate nor becoming indurated, 0.5 mm. long, not accrescent, brownish.. Male inflorescences simply racemose, few-flowered, 1–1.5 cm. long, pedunculate; peduncle and axis evenly adpressed pubescent; bracts linear-setaceous, 0.7 mm. long, weak, glabrous.. Male flowers: pedicels slender, 2–4 mm. long, glabrous, articulate at the base; calyx-lobes (3–)4(–5), broadly ovate, 2 mm. long, 1.5 mm. wide, subacute, glabrous without and within, pale greenish cream with a brown nerve-network, translucent; extrastaminal glands ± 10, minute, rounded, tipped with a few hairs; interstaminal glands smaller, much shorter than the stamens, truncate, tipped with a tuft of hairs; stamens 30–35, outer 10–12, the rest central, 1 mm. long, anthers yellow.. Female inflorescences simply racemose, 1–4-flowered, 2–3.5 cm. long, long-pedunculate; peduncle and axis evenly to sparingly adpressed pubescent or puberulous; bracts narrowly lanceolate, 1 mm. long, acute, pubescent.. Female flowers: pedicels 3–6 mm. long, extending to 1 cm. in fruit, sparingly adpressed pubescent or puberulous, articulate at or just below the middle; calyx-lobes (3–)4, broadly ovate, 2 mm. long, 1.5 mm. wide, subacute or obtuse, sparingly adpressed pubescent without, glabrous within, green, opaque; disc urceolate, thin, shallowly trilobate, 1.5–3 mm. diameter, sparingly ciliate; ovary trilobate, 1–1.5 mm. diameter, glabrous, subglabrous or evenly pubescent; styles 3, shortly united at the base, 1 mm. long, recurved, stigmas subentire to fimbriate throughout.. Fruit trilobate, 4 mm. long, 6–7 mm. diameter, cocci not distinct, glabrous or sparingly pubescent, pale green at first, red when ripe.. Seeds 3–4 mm. diameter, muricate, aril bright red, drying greyish white.

Male flowers: pedicels 2–4 mm long, slender, glabrous, jointed at the base; buds less than 1 mm across, conic-quadrangular, apiculate, truncate at the base, glabrous; calyx lobes 4, 2 × 1.5 mm broadly ovate, subacute, pale greenish-cream; extrastaminal disk glands c. 10, minute, rounded, tipped with a few hairs; interstaminal glands much shorter than the stamens, truncate, each tipped with a hair tuft; stamens 30–35, 10–12 outer, the rest central, 1 mm long, anthers minute, yellow; sometimes the whole centre of the male flower replaced by the shiny, black, quandrangular sclerotium of a fungus, ? Sclerotinia sp., in which case the buds are swollen to 3 × 3 mm.
Female flowers: pedicels 3–6 mm long, extending a little in fruit, sparingly appressed-pubescent, jointed below the middle; calyx lobes 4, 2 × 1.5 mm, broadly ovate, subacute or obtuse, subglabrous, pale green; disk 1.5–3 mm in diameter, urceolate, thin, shallowly 3-lobed, sparingly ciliate; ovary 1–1.5 mm in diameter, 3-lobed, glabrous, subglabrous or evenly pubescent; styles 3, 1.5 mm long, shortly united at the base, spreading, stigmas proximally subentire, distally laciniate.
Leaf blades 1–7.5 × 0.5–2.5 cm, elliptic-lanceolate, acutely long-acuminate apically, coarsely glandular serrate-dentate to subentire on the margins, cuneate at the base, membranous, sparingly pubescent on both surfaces, more evenly so along the midrib and main nerves, drying dark green; lateral nerves in 3–4 pairs, ascending, not or weakly looped, scarcely prominent above or beneath.
