Characteristics

A shrub or short-trunked spreading tree with an open crown, 2–3.5 m. tall; bark smooth or rough, longitudinally, quadrangularly or reticulately-fissured, grey.. Branches gnarled, brittle; branchlets stout, pubescent.. Leaves sessile or shortly petiolate; leaf-blades broadly obovate, up to 40 cm. long and 25 cm. wide, rounded at the apex, cuneate-attenuate at the base, thinly coriaceous, lateral nerves 10–15 pairs, camptodromous or weakly brochidodromous, not prominent above, fairly prominent beneath, tertiary nerves not parallel, pubescent or pilose above and beneath (especially along the midrib and main nerves) when young, later ± glabrescent above, mid green and slightly shiny above, glaucous beneath.. Stipules linear to subulate, 0.5–1 cm. long, evenly pubescent, soon caducous.. Male peduncle up to 6 cm., evenly pubescent; bracts 10, oblong, 1–1.5 cm. long, (3–)5–7 mm. wide, pubescent without, glabrous within, yellowish; head of ♂ flowers 0.7–1 cm. across.. Male flowers: calyx-lobes 5–6, oblong-linear to setaceous, 1.5 mm. long, pubescent at the apex; stamens 5, filaments very short, anthers 1 mm. long, yellow; pistillode hypocrateriform, pubescent at the apex.. Female peduncle and bracts ± as in ♂.. Female flower: calyx-lobes broadly triangular, 1 mm. long and wide, pubescent at the apex; ovary ellipsoid-subglobose, 4–5 mm. long, 3–4 mm. across, glabrous; styles 3–5, 7–8 mm. long, ander-like.. Fruits depressed-subglobose, scarcely 3–5-lobed, up to 3 cm. long and 4.5 cm. across, smooth, glabrous, apple-green, often with brownish markings; mesocarp ± 3 mm. thick.. Pyrenes 3–5, up to 2.3 cm. long and 1.4 cm. wide, strongly carinate.

Leaves sessile or shortly petiolate, or petioles up to 7 cm long (var. petiolata).Leaf blades up to 40 × 25 cm, broadly obovate to obovate-oblanceolate, rounded at the apex, cuneate-attenuate at the base, thinly coriaceous; indumentum pubescent or pilose at first, especially along the midrib and main nerves, later ± glabrescent on leaf upper surface, minutely glandular-lepidote between the hairs on leaf lower surface; lamina glaucous or pale green, turning yellow when old; lateral nerves in up to 15 pairs, the lower camptodromous, the upper weakly to strongly brochidodromous, not prominent above, prominent beneath, tertiary nerves arcuate.
A shrub or small tree. It grows 4.5 m tall. The small branches are stout and brittle. The young twigs are hairy. The leaf blades are 40 cm long by 25 cm wide. They are broadly oval. They are rounded at the tip and wedge shaped at the base. They are thinly leathery. The leaves are grey green or pale green. Male and female flowers are separate. Male flowers are larger. The fruit are 3 cm long by 4-5 cm wide. The are round but flattened. They have shallow lobes. They are green but with brown marks.
Female flower: calyx lobes 1 × 1 mm, broadly triangular, pubescent at the apex; ovary 4–5 × 4–5 mm, subglobose, glabrous, yellowish-green, white-speckled; styles 3(5), 7–8 mm long, somewhat irregularly multipartite, the segments linear-setaceous, pale yellow.
Fruits 3 × 4–5 cm, depressed-globose, shallowly (3)4(5)-lobed, smooth, glabrous, apple-green with brownish markings; mesocarp c. 3 mm thick, sticky, yellow; pyrenes 3–5, c. 2 × 1.5 cm, strongly carinate, the lateral lobes irregularly crenellate.
Male flowers: calyx lobes 5–6, 1.5 mm long, linear-oblong to setaceous, pubescent at the apex; stamens 5, filaments very short, anthers 1 mm long, pale yellow, turning buff; pistillode hypocrateriform, pubescent at the apex.
Male peduncles c. 4–6(9) cm long, pubescent; bracts 10, 10–15 × 3–7 mm, oblong, pubescent without, glabrous within, yellowish-green at first, turning cream-yellow; head 0.7–1 cm in diameter.
Female peduncles c. 1 cm long, extending to up to 6 cm long in fruit, stouter than the male; bracts more or less as in male inflorescence.
An open-branched shrub or small tree up to 4.5 m high, with stout, brittle branchlets.
Stipules 5–7 mm long, linear to narrowly lanceolate, pubescent, soon falling.
Bark smooth or rough, longitudinally or quadrangularly-fissured.
Inflorescences usually borne just below the leaves.
Young twigs pubescent.
