Flowers

Petals about 4 mm long. A conspicuous, comparatively large, green gland present on the back of each anther close to the point of attachment of the filament. Surface of the ovary concave at the apex.

Fruit

Capsules usually 5-celled, conspicuously domed at the apex. Seeds about 2-2.5 x 0.3-0.5 mm.

Seedlings

Cotyledons obovate, about +/- 2 mm long. At the tenth leaf stage: leaf blade obovate, +/- sessile, glabrous on the upper surface; oil dots very small, visible only with a lens. Seed germination time 31 to 34 days.

Distribution and Ecology

Endemic to NEQ, known only from the mountains north west of Mossman, the Mt Spurgeon-Mt Lewis area and the Bellenden Ker Range. Altitudinal range from 1100-1550 m. Grows in windswept vegetation on high exposed ridges in areas otherwise clothed in mountain rain forest.

Natural History & Notes

A very long lived tree in nature. It is sometimes cultivated for its small white flowers but needs cool and moist conditions to do well.

This plant was used in colonial medicine, leaves ad young shoots of all species reputed useful for urinary complaints. Cribb (1981).
