Leaves opposite (rarely in whorls of 3), ± coriaceous, petiolate; lamina (2) 4–11 × (1) 1·5–6 cm., very variable in size, shape and texture, lanceolate or oblanceolate to broadly ovate or obovate, acute to rounded-apiculate at the apex, cuneate to rounded at the base, dark bluish-or yellowish-green above, paler below, flat or ± bullate, with main lateral veins prominent on both sides, tertiary venation usually ± prominent above, margins sometimes incrassate, and with branched translucent glandular canals visible in the young leaves at least, and longitudinal opaque canals visible below; petiole 3–18 mm. long and grooved above, transversely wrinkled; ligule prominent.
A small branched tree. It grows to 20 m tall. The bark is dark grey and smooth. The leaves are simple and opposite or in rings. The leaf stalk is 18 mm long and has wings.
