Petioles usually swollen about the middle and thicker at that point than at the junction with the leaf blade. Leaf blades rather hard and leathery. Vascular strands scattered all over transverse sections of the twigs. Flowers Flowers conspicuously perfumed. 'Sepals' pale green, small and inconspicuous, about 1-2 x 1 mm. Petals about 4-7 x 3 mm. Stamens 6, anthers about 4 mm long, filaments about 0.5 mm long. Pollen white. 3-lobed. Fruit Fruits globular or depressed globular, about 11-15 x 17-18 mm, stalks slender. Seeds variable in size and Leaves and fruits. Copyright CSIRO shape, about 8-11 diam. Embryo white, about 3-3.5 x 1.5 mm, held in the endosperm just beneath the surface of the testa. Endosperm white to translucent, firm, +/- granular or cellular. Seedlings Cataphylls 2-4, about 10-16 mm long are usually produced before the first true leaf. First true leaf ovate, leaf blade about 5 x 3 cm, apex acuminate, base +/- truncate, petiole about 15 mm long. Leaf blade 3-veined with the major veins extending to the apex, two other minor veins extend from the base just inside the blade margin. Stems and petioles clothed in short brown hairs which are shed. At the tenth leaf stage: usually Fruit, side views, transverse and longitudinal sections. multistemmed with the stems arising from a rhizome. Leaf blades up to 11-12 x 4-5 cm, apex acuminate, Copyright W. T. Cooper base attenuate, petiole 2 cm or more long, swollen and clothed in short erect hairs just prior to its junction with the stem. Leaf blades predominantly 3-veined, sometimes 5-veined. Seed germination time 25 to 49 days. Distribution and Ecology Occurs in NEQ, CEQ and southwards as far as Victoria. Altitudinal range in NEQ from 500-1400 m. Grows mainly in upland rain forest. Also occurs in New Guinea. Natural History & Notes
