Descriptions

Morphology General Habit
Shrub or tree (1–)4.5–30 m. high, much branched; bark purplish brown, prominently lenticellate; branches 4-lined or not, flattened to quadrangular and pale grey when young, becoming terete and vinous red to red-brown with prominent whitish lenticels.
Morphology Leaves
Leaves with lamina yellowish green and dull above, paler green to grey-brown beneath, elliptic or lanceolate to obovate or oblanceolate, (5–)6.5–14(–18) × (2–)2.7–8.1(–10) cm., acute or shortly acuminate to obtuse or more rarely rounded at the apex, with margin indurated, glandular-crenulate-denticulate on flowering shoots, shortly appressed- or incurved-spinulose-denticulate on juvenile shoots, cuneate or rarely rounded at the base, coriaceous, with densely reticulate venation prominent beneath but not usually above; petiole 5–13 mm. long.
Morphology Reproductive morphology Inflorescences
Cymes in axils of bracts on specialised shoots 3–5 cm. long arising from axils of bract-like prophylls on current shoots, forming a paniculate many-flowered inflorescence; peduncles (of cymes) often indistinguishable from ‘panicle’ branches; pedicels ± 1 mm. long, angular, articulated at the base; flowers sweetly scented, 1–7(–11) in each cyme, 3–5.5 mm. in diameter, dioecious or polygamous.
Morphology Reproductive morphology Flowers Calyx
Sepals 4–5, ± unequal, semicircular, ± 1 mm. long, with margin entire or very finely serrulate.
Morphology Reproductive morphology Flowers Corolla
Petals 4–5, white or green to pale yellow, ovate to oblong, often shortly clawed, 1.5–2 mm. long in ♀ flowers, 2–2.5 mm. long in ♂ flowers, with longitudinal ridges, entire.
Morphology Reproductive morphology Flowers
Male flowers:stamens 4–5, ± 1 mm. long; disc slightly 4–5-lobed, flat; pistillode immersed in disc. Female flowers with, or rarely without, (4–)5 petaloid staminodes; disc 4–5-lobed, annular; ovary 2–3-locular, ovoid-conic, ± 1 mm. long.
sex Male
Male flowers:stamens 4–5, ± 1 mm. long; disc slightly 4–5-lobed, flat; pistillode immersed in disc.
sex Female
Female flowers with, or rarely without, (4–)5 petaloid staminodes; disc 4–5-lobed, annular; ovary 2–3-locular, ovoid-conic, ± 1 mm. long.
