Satinash, Rocky River; Rocky River Satinash
Inflorescence bracts deciduous; present or absent at anthesis. Calyx tube (hypanthium) + pedicel about 3-4 mm long, calyx tube (hypanthium) about 2-2.5 mm diam., calyx lobes +/- uniform, rounded, concave, about 0.5 mm long. Petals +/- orbicular, about 1.5 mm diam.; oil dots comparatively large and conspicuous, about 40 or more per petal. Outer staminal filaments about 0.5 mm long, anthers wider than long, about 0.2 x 0.4 mm, gland comparatively large, conspicuous, terminal. Placentas confined to the apex of each locule. Ovules pendulous, about four per locule. Style about 1.4-1.6 mm long.
Fruits hemispherical to depressed globular, attaining about 35-40 x 40 mm, calyx lobes deciduous, but the apex of the fruit marked with a tonsure-like scar attaining about 20-30 mm diam., pericarp rather leathery, brittle, granular in texture. Seed about 15-20 x 20-30 mm. Cotyledons scarcely separable, joined by the haustorium-like intrusion from the apex of the fruit, so that the cotyledons are +/- ruminate or at least texturally different towards the centre.
This species is not used commercially at present but produces millable logs that could be sawn for structural timber. Wood specific gravity 0.91. Hyland (1983).
