Characteristics

Much-branched aromatic shrub, small tree or liane 1.8–9 m. long or tall; branchlets with rather coarse granular stellate and often simple hairs when young, later glabrescent or glabrous, blackish, wrinkled and lenticellate.. Leaf-blades oblanceolate, obovate or oblong, (0.7–)3–8(–12) cm. long, (0.5–)1.3–3.9(–4.9) cm. wide, mostly distinctly acuminate at the apex or less often obtuse, rounded or more usually cordate at the base, somewhat coriaceous, above mostly deep green and sparsely pubescent with simple or stellate hairs or glabrous save on midrib, sparsely to densely covered with coarse openly spaced ferruginous stellate hairs beneath and with simple hairs on the nerves, rarely glabrous beneath; lateral nerves slightly impressed above; venation reticulate, usually prominent on both surfaces; petiole l–2.5(–4) cm. long, stellate-pubescent.. Flowers terminal or extra-axillary, solitary or in 2-flowered cymes, hanging; peduncle ± 2–3 mm. long; pedicels0.5–2 cm. long, stellate-tomentose; bracts oblong, 2–3 mm. long, 1 mm. wide; bracteoles minute, 1 mm. long, soon deciduous.. Sepals ovate or ovate-triangular, 4–6 mm. long and wide, obtuse to acute, shortly united at the base, often remaining as a loose persistent collar, completely covering the petals in bud, pubescent with coarse ferruginous stellate hairs.. Petals white or yellow, oblong or oblong-lanceolate, subequal, 0.6–1.3 cm. long, 3–6 mm. wide, acute or obtuse, thin or slightly fleshy, puberulous on both surfaces with stellate hairs.. Stamens ± 1 mm. long; connective-prolongation broadened, truncate.. Carpels mostly 20–25.. Fruiting pedicels 1–2 cm. long; monocarps orange, 5–15, globose or ovoid, 0.8–1.6 cm. long and wide, l–4(–?6)-seeded, not constricted between the seeds, obtuse, densely tomentose with ferruginous or brown hairs, rugose or verrucose; stipes 2–3 mm. long.. Seeds shining brown, irregularly compressed-ovoid or shaped like the segment of an orange, 7–8 mm. long, 4–5 mm. wide, 3–4 mm. thick, usually with at least one sharp angle, with a paler irregularly quadrate arillar collar.. Fig. 2/2, p. 11.

Leaves petiolate; lamina (2) 3–8 (11.5) x 1.3–3.9 cm., oblanceolate or obovate to oblong, obtuse or usually with an acute acumen up to 2 cm. long at the apex, cordate (rarely rounded) at the base, subcoriaceous, deep glossy green or greyish-green and sparsely pubescent with simple (rarely stellate) hairs or glabrous (except along the midrib) above, paler green and sparsely or ± densely stellate-pubescent below (pilose with simple hairs along the nerves), with lateral nerves prominent below and densely reticulate venation prominent on both surfaces; petiole 1–2.5 (4) mm. long, rusty-pilose.
A shrub or climber. It can grow 5 m high. The leaves are usually hairy underneath. The leaves are rounded or heart shaped at the base. It narrows to the tip. The flowers are yellow. They occur singly or in pairs. The fruit are as several warted sections. They are yellow when ripe.
