A small tree less than 30 cm dbh. Blaze finely layered with fibrous stripes in the outer blaze.
Inflorescence 1-4 flowered, appear terminal or axillary, solitary. Flowers 12-13 mm across. Bracts 3-5, about 0.7-2 x 0.8-1.4 mm. Pedicels about 4-7 mm long, pubescent. Sepals depressed ovate to ovate, about 1-3 x 1-3.5 mm, pubescent outside, glabrous inside. Petals slightly imbricate or valvate (?) at the apex, spreading, narrowly to broadly (triangular-)ovate to elliptic. Outer 3 petals about 5-22 x 3-8 mm wide. Inner 3 petals about 5-16 x 3-6.5 mm, pubescent on both sides. Stamens ca. 28, about 1.2-2 mm long, apex shield-like, elongated in the inner whorl. Ovaries 2-14, densely hairy. Ovules 6 or 7 per ovary. Stigma globose to discoid or to oblong-obovoid, fleshy, sparsely hairy or glabrous.
First pair of leaves shortly petiolate, alternate, ovate, margins smooth, mainly glabrous. Small oil dots visible with a lens. Stem clothed in cream or pale brown hairs. At the tenth leaf stage: leaves ovate or lanceolate, apex acute or acuminate, base obtuse or cuneate; petioles short, pubescent.
Distribution and Ecology
A widespread but inconspicuous species in WA, NT and CYP. Altitudinal range from near sea level to 300 m. Grows in the drier types of rain forest and in monsoon forest. Also occurs in Malesia.Jessup (2007) distinguishes two subspecies, viz. subsp. cylindrocarpa and subsp. trichocarpa. The differences are slight and appear to depend on the degree of hairiness of the fruiting carpels.
