Shrubs 450 mm tall (plants killed in a previous fire were up to 1.7 m tall) with many stems arising from a single trunk in the grass or peat. Branches erect, slender, glabrous, straight; bark smooth with raised leaf scars, light brown or green. Branchlets very slender, somewhat lax, numerous, thinly puberulous, with raised glands, one on either side of each leaf base and others below, all turgid with oil smelling of sweet cedarwood. Leaves 6-7.5 mm long including the petiole 1 mm long. 2-2.3 mm broad, elliptic, acute, apiculate, glabrous, alternate, spreading-erect: abaxial surface with a few gland dots along either side of the sunken midrib; margins lumpy with swollen gland dots. Inflorescence solitary or sometimes twin, arising in the axils of the leaves, short-pedicellate; flowers monoeciously-polygamous with male flowers outnumbering the female flowers. Bract vestigial, 0.7 mm long, 0.2 mm broad, oblong, obtuse, ciliate, pinkish: a second bract subtends another immature floral bud. Bracteoles two, vestigial, 0.3 mm long, subulate, spiky ciliate, arising from a broad connate decurrent scale forming part of the pedicel. Pedicel about 1 mm long, glabrous. Calyx 4-partite, glabrous, gland-dotted; lobes 1-2.2 mm long, 0.6-0.7 mm broad, lanceolate acute, glabrous, gland-dotted, ciliate, persisting. Petals and staminodes absent. Filaments four, becoming 1.6 mm long, acicular, glabrous, pink, delapsing. Anthers four, 3 mm long, 1.1 mm broad, glabrous, deep red, apex with a large oil gland crowned with a sharp point. Pollen 22 µm diam., subspherical. Stigma at first a somewhat thumb-shaped organ arising at the side of the base of the horn, smooth, red in colour, becoming about 1.4 mm long, 0.3 mm diameter, eventually delapsing. Style absent. Ovary vestigial in male flowers; in hermaphrodite flowers superior with two ovules attached at the side where the stigma projects. Fruit 1-carpellate, 6 mm long including a short blunt horn 2 mm long, 2.4 mm broad, glabrous, gland-dotted. Seed 3.5-3.9 mm long, 1.5 mm broad, black, shining; aril black, inconspicuous.
