Inflorescence bracts normally present at anthesis. Calyx tube (hypanthium) + pedicel about 3-4.5 mm long, calyx tube (hypanthium) about 2-3.5 mm diam., calyx lobes rounded, about 0.5 mm long. Petals variable in size and shape, +/- orbicular, outer petals about 2 mm diam; oil dots difficult to distinguish, fewer than ten per petal, concentrated towards the base. Outer anther filaments about 1-2 mm long, anthers wider than long, about 0.3 x 0.5 mm, gland comparatively large, terminal, near the front of the anther. Placentas confined to the apex of each locule. Ovules pendulous, about 4-6 per locule. Style about 1-1.5 mm long, shorter than the stamens.
Fruits depressed globular to broadly turbinate, attaining about 50-60 mm diam., with a distinct calyx rim or tonsure-like scar persisting at the top; calyx lobes deciduous or at least not obvious; pericarp leathery to almost woody in texture. Seed solitary, attaining about 30-40 mm diam., cotyledons fused, +/- ruminate, or at least texturally different towards the centre because of the haustorium-like intrusion from the apex of the fruit. Intercotyledonary inclusion unbranched but swollen or enlarged towards the central part of the cotyledons.
Cataphylls about 4-6 pairs, opposite or subopposite before the first true leaves and also between leaves at later stages. At the tenth leaf stage: seedling completely glabrous, leaf blade lanceolate, apex acute or apiculate, base cuneate, a double intramarginal vein present; oil dots small and numerous, visible only with a lens. Seed germination time 92 to 153 days.
This species produces millable logs and the timber is marketed as Cassowary Satinash, a useful general purpose structural timber. Wood specific gravity 0.64-0.68. Hyland (1983).
