Bark exudate generally rather slow.
Petioles produce a watery, milky exudate. Leaf blades about 6-15 x 2-4.5 cm. Midrib and main lateral veins raised on the upper surface of the leaf blade.
Sepals ovate, about 3.5-4 x 3-3.3 mm, yellowish sericeous or pubescent on the outer surface, glabrous on the inner surface. Corolla about 3-4.5 mm long. Stamens inserted in the basal quarter of the corolla, filaments about 0.5 mm long, anthers about 1 mm long. Staminodes oblong or linear, about 1 mm long. Ovary about 1 mm long, brownish yellow, hirsute. Style about 2-3 mm long.
Fruits ovoid or globose-ellipsoid, about 15-30 x 12-20 mm. Seeds, up to five per fruit, ellipsoid, laterally compressed, about 10-12 x 5-9 x 3-4 mm. Testa hard and woody, hilum about 1-2 mm wide and slightly shorter than the seed.
Cotyledons elliptic to obovate, about 20-30 mm long, midrib slightly raised on the upper surface. First pair of true leaves elliptic, narrowly elliptic or obovate, margins entire. At the tenth leaf stage: leaf blade narrowly obovate, apex acute, base attenuate, upper surface glabrous or with a few scattered hairs on the midrib near the base, about 8-12 lateral veins each side of the midrib; exudate from petiole milky, but meagre and slow to appear; petiole, stem and terminal bud clothed in prostrate, brown hairs.
Distribution and Ecology
Endemic to Australia, occurs in CYP, NEQ and southwards as far as north-eastern New South Wales. Altitudinal range from sea level to 450 m. Grows in monsoon forest and drier, more seasonal rain forest with Kauri Pine (Agathis robusta).
Produces a useful general purpose timber.
