Bark brown to orange brown, tending to be papery.
Leaf blades rather large, about 7-14 x 4-9 cm, thick and leathery, about 8-15 pairs of lateral veins. Oil dots visible with a lens if not visible to the naked eye. Larger twigs with papery or flaky bark.
Bracts present or absent at anthesis. Calyx tube (hypanthium) + pedicel about 6-12 mm long, calyx tube (hypanthium) about 6-8 mm diam., calyx lobes +/- uniform (sometimes one lobe longer than the rest), rounded to broadly triangular, about 1-2 mm long. Petals +/- orbicular, shortly clawed, about 6 mm diam., oil dots visible, smallish, about 100 per petal. Outer staminal filaments about 9-18 mm long, anthers about 0.8-1 x 0.7 mm, gland dorsal, near the apex of the anther. Ovules about 25-35 per locule, placentas central, ovules radiating, ascending. Style about 8-14 mm long, shorter than the stamens.
Fruits depressed globular, globular-ovoid or doliform, about 30-40 x 30-40 mm, calyx lobes persistent, about 2 mm long, pericarp fleshy, but coarsely granular close to the seed. Seed solitary, globular, slightly bilobed, about 10-25 mm diam., testa adhering to the pericarp and adhering slightly to the rugose surface of the cotyledons by means of granular horny intrusions, cotyledons uniformly textured except for the +/- ruminate peripheral section.
Distribution and Ecology
Occurs in NT, CYP and NEQ. Altitudinal range from sea level to 450 m. Grows in well developed rain forest but is most characteristic of beach forest either on sand or on rocky headlands. Also occurs in New Guinea.
Fallen fruit eaten by Cassowaries. Cooper & Cooper (1994). This species has potential in horticulture as a shade tree for parks and gardens and as a street tree. Can withstand strong winds and has large white flowers and fruits.
This subspecies occasionally produces millable logs which are marketed under the trade name of Flaky-barked Satinash. Wood specific gravity 0.69-0.96. The fruit is sometimes eaten but has no commercial value. Hyland (1983).
