Outer bark often rather pale.
Inflorescence bracts deciduous, absent at anthesis. Calyx tube (hypanthium) + pedicel about 10-20 mm long, calyx tube (hypanthium) about 2-5 mm diam., calyx lobes about 4-5, +/- rounded, small and inconspicuous, seldom exceeding 0.5 mm in length. Petals 6-8, +/- orbicular, attaining about 2-3 mm diam., +/- cohering, largely as a result of the apices of all petals being folded into a cylinder at the centre, between the staminal filaments. Oil dots about 20-30 per larger petal. Outer staminal filaments about 3-8 mm long, anthers about 0.8 x 0.5 mm, gland terminal, reasonably conspicuous. About 9-16 ovules per locule. Style rather stout, about 3-8 mm long, approximating or slightly exceeding the stamens.
Cataphylls about 3 pairs before the first pair of true leaves and sometimes between the leaves at later stages. At the tenth leaf stage: twigs conspicuously 4-angled or shortly winged, leaf blade lanceolate or ovate, apex acuminate or acute, base cuneate; oil dots numerous, clearly visible with a lens or just visible to the naked eye. Seed germination time 38 to 95 days.
This species produces a useful structural timber which is marketed as Grey Satinash.
Wood specific gravity 0.72-0.88. Hyland (1983).
