Characteristics

A much-branched evergreen tree up to 20 cm. tall with widely-spreading branches.. Bark pale grey or dark brown, deeply longitudinally fissured.. Twigs relatively slender, with the leaf-scar margins not or scarcely raised, evenly fulvous to ferruginous pubescent at first, later glabrescent.. Leaves sometimes alternate, more often subopposite or opposite and decussate; petioles (2.5–)4–8(–10) cm. long, finely fulvous or sometimes ferruginous pubescent; leaflets (3–)5–7(–8), elliptic-lanceolate, elliptic or elliptic-oblanceolate, the median equalling or not much larger than the laterals, (2–)5–10(–16) cm. long, (0.5–)1.5–4.5 cm. wide, acutely or obtusely acuminate, attenuate or cuneate, sometimes undulate, subcoriaceous, lateral nerves 10–20(–30) pairs, looped well within the margin, and with a further irregular series of loops nearer the margin, slightly prominent above, scarcely so beneath, sparingly pubescent along the midrib but otherwise glabrous above, evenly pubescent along the midrib but otherwise sparingly pubescent beneath, shining and dark green above, duller and paler beneath; petiolules 2–5(–11) mm. long.. Male inflorescences: peduncles 1.2–1.5(–2) cm. long, finely fulvous-pubescent; bracts minute; flowers subcapitate.. Female inflorescences: peduncles 5 mm. long, extending to 1(–2) cm. in fruit, commonly 1-flowered, more rarely 2–3-flowered; bracts oblong or linear-oblong, 3–6 mm. long, fulvous or ferruginous pubescent.. Male flowers: pedicels up to 2 mm. long; sepals 6–7, oblong, 1 mm. long, obtuse, ferruginous pubescent without, glabrous within except towards the apex; stamens 5–7, 3–4 mm. long, anthers 0.8–1 mm. long; disc very irregularly lobulate, 1 mm. high, 1 mm. diameter, conical at the apex; pistillode minute or 0.. Female flowers: pedicels 5 mm. long, extending to 1 cm. in fruit, fulvous or ferruginous pubescent; sepals oblong or oblong-oblanceolate, somewhat foliaceous, 5–12 mm. long, 1.5–3 mm. wide, obtuse, ferruginous pubescent without, fulvous pubescent within; disc 2.5 mm. diameter; ovary 2–3-locular, subglobose, 2–2.5 mm. long, 3 mm. diameter, densely fulvous tomentose; styles 2–3, 2 mm. long, densely white pubescent, stigmas brownish grey, velvety.. Fruit globose or subglobose, with 2–3 circumferential lines corresponding to the dehiscence sutures and septa, 1.5–2 cm. long, 1.5–1.8 cm. wide, glabrescent, yellow when ripe.. Seeds compressed ovoid, 1–1.3 cm. long, 0.8–1 cm. wide, 3 mm. deep, brown.
