Swamp Satinash; Satinash, Yarrabah; Yarrabah Satinash

Bark usually reddish brown or orange-brown.

Oil dots visible with a lens if not visible to the naked eye. Leaf bearing twigs usually 4-angled or square in transverse section. Leaf blades about 3-13 x 1.5-4.5 cm. Midrib and lateral veins translucent. Old leaves turn orange-red prior to falling.

Bracts caducous, absent at anthesis. Calyx tube (hypanthium) sessile or tapering into a short pedicel, calyx tube (hypanthium) + pedicel about 2.5-4 mm long, tube (hypanthium) about 2-3.5 mm diam., calyx lobes rounded, about 0.3-0.5 mm long. Petals orbicular, about 3-3.5 mm diam., oil dots about 5-10, confined to the base and middle of each petal. Outer staminal filaments about 3-7 mm long, anthers about 0.3 x 0.3 mm, gland dark, terminal and conspicuous. Ovules about 8-15 per locule, placentas central, ovules radiating. Style about 5-7.5 mm long, equal to or exceeding the stamens.

Fruits globular or depressed globular, attaining about 9 x 13 mm, calyx lobes persistent, small and inconspicuous, about 0.5 mm long, pericarp succulent. Seed attaining about 7-9 mm diam., testa free from the pericarp or easily separated from it and the uniformly textured cotyledons. Radicle lateral, cotyledonary stipules present.

Cataphylls about 2-4 pairs. At the tenth leaf stage: leaf blade obovate, apex obtuse or shortly acuminate, base attenuate, glabrous; oil dots small, visible with a lens. Seed germination time 18 to 54 days.

Endemic to Australia, occurs in WA, NT, CYP and NEQ. Altitudinal range from sea level to 600 m. Usually grows in swampy situations or near permanent water in rain forest or gallery forest. Not known from New Guinea but its occurrence there is a distinct possibility.

Although frequently growing to a well formed tree of reasonable size, little is known about the timber qualities of this species.
