White, C.T. (1936) Proceedings of the Royal Society of Queensland 47: 52. Type: Thornton Peak, in low scrub at the summit, L.J. Brass, No. 2277 (fruits) March 14.

Stem

Tree to 18 m. Bark exudate not copious but quite conspicuous because of its yellow colour. Dioecious.

Leaves

Petioles and twigs produce a yellow exudate. Petioles 5-12 mm; leaf blades 25-125 mm long x 16-63 mm wide, base attenuate or cuneate; apex acute, obtuse or emarginate; margin recurved; secondary vens 12-35 pairs.

Flowers

Male inflorescences terminal, panicle 3-18-flowered; male flowers: sepals 4, 2-whorled, outer pair joined, D-shaped or ovate-orbicular, 4-6.5 mm long x 4-6.5 mm wide, inner pair free, orbicular or oblong-orbicular, 7-8 mm long x 6-7 mm wide; petals 4, free, orbicular, 9-14 mm long  x 8-14 mm wide; stamens aggregated into four stout phalanges; disk absent or not obvious in the male flower. Female inflorescence terminal, a solitary flower; sepals 4, 2-whorled, outer pair joined, oblong, 5 mm long x 4 mm wide; inner pair free, broadly ovate or orbicular, 6-8 mm long x 5-7 mm wide; petals 4, free, orbicular, 8-10 mm long x 8-10 mm wide; four stout staminodal phalanges; stigma sessile, domed, 4.5-5.5 mm diam.

Fruit

Fruits a fleshy berry, depressed globular, about 22-45 mm long x 27-50 mm wide, dark red to blackish. Calyx lobes four, persistent. Stigma persistent. Seeds 1-4, 12-22 mm long,  10-18 mm wide; aril fleshy, dark red.

Seedlings

Leaves and roots arise from shoots at opposite ends of the seed. A number of alternate and opposite cataphylls produced before the first true leaves. At the tenth leaf stage: leaves narrowly elliptic, glabrous, underside with a number of wavy +/- parallel latex canals crossing the main lateral veins; lateral veins fusing with an intramarginal vein very close to the margin of the leaf blade; a stipule-like appendage attached to each petiole between it and the stem. Seed germination time 90 to 236 days.

Distribution and Ecology

Endemic to NEQ, restricted to the mountains from Mt Sorrow to Mossman Bluff and west to the Mt Lewis - Mt Spurgeon areas. Altitudinal range from 500-1500 m. Grows in mountain rain forest often as a small stunted tree on windswept ridges.
