Stem

Small trees 4-10 m tall. Branches very resinous towards apex, hairy.

Leaves

Stipules interpetiolar, triangular, keeled, hairy; petioles 4-8 mm long, channelled; blades 6.7-13 cm x 2.9-6 cm. Domatia present, obvious, usually a few on each side of midrib.

Flowers

Inflorescences generally 6 to 9-flowered, sessile or nearly so. Flower pedicel 2.5-6 mm long, hairy; calyx 2.5 x 2 mm, glabrous; corolla cream or pale yellow, orange or brown when aged, 9-13.5 mm long.

Fruit

Fruit on slender pedicels 6-15 mm long, orange-red when ripe, laterally compressed, 8-12 x 6-11 mm. Seed smooth or slighly wrinkled.

Seedlings

Cotyledons linear-ovate, about 19-33 x 5-7 mm, midrib raised on the upper surface. Cotyledonary stipules triangular, apex pointed. First pair of leaves glabrous, elliptic, apex bluntly pointed, base cuneate, midrib raised on the upper surface. Hypocotyl flattened, elliptical in transverse section. At the tenth leaf stage: leaf blade elliptic to obovate, about 70-80 mm long, apex acuminate; stipules interpetiolar, wide at the base but narrowed abruptly to a fine point at the apex.

Distribution and Ecology

Endemic to NEQ, from Daintree River to near Cardwell. Altitudinal range near sea level. Grows in lowland areas along creeks, near swampy lowland forests, beach ridges and coastal sands, and in vine thickets on sandy soil.

Natural History

Distinguishable by the 5-9-flowered, sessile inflorescences, hairy branchlets and prescence of domatia.
