Lateral veins, about 7-12 on each side of the midrib, forming loops well inside the blade margin. Midrib slightly raised on the upper surface. Petiole channelled on the upper surface. Small oil dots visible with a lens.

Flowers

Flowers about 3-6 mm diam. Connective extended beyond the apex of the anther as a pubescent, broadly spathulate appendage. Carpels pubescent, about 20-30, receptacle +/- domed, pubescent between the carpels.

Seedlings

Cotyledons ovate, about 10-12 x 9-10 mm. First pair of leaves toothed. At the tenth leaf stage: leaf blade elliptic with scattered pale hairs on the upper surface, apex mucronate, base attenuate, midrib raised on the upper surface, margin dentate. Seed germination time 135 to 188 days.

Distribution and Ecology

Endemic to NEQ. Altitudinal range from 350-1150 m. Grows in well developed upland and mountain rain forest but often found on rain forest margins where it can be one of the components of the rain forest elements advancing into the wet sclerophyll forest.
