Jessup, L.W. (1984) Austrobaileya 2(3): 227.
A small tree seldom exceeding 20 cm dbh. Subrhytidome layer very dark, almost black. Blaze odour strong, resembling incense.
Leaf blades about 10-30 x 3-7 cm. Numerous small oil dots visible with a lens. Petiole transversely wrinkled and grooved on the upper surface. Fine oak grain in the twigs but more noticeable in the twig bark. Freshly broken twigs have a strong odour.
Pedicels about 15-32 mm long, submedial bract about 1.2-2 mm long. Calyx lobes broadly ovate or suborbicular, about 2-3 mm long, puberulent outside, glabrous inside. Outer petals broadly obovate to suborbicular, about 9-9.5 x 7.5-8 mm, puberulent outside, glabrous inside; inner petals puberulent outside, glabrous inside, forming a dome about 8.5-12 x 9-12 mm. Ovaries about 38, ovules two or three per ovary.
One cataphyll sometimes produced before the first true leaves. First pair of true leaves shortly petiolate, ovate-lanceolate, margins smooth, mainly glabrous on the upper surface, sometimes pubescent on the lower surface. Oil dots visible with a lens. Stem sparsely clothed in short pale yellow-brown hairs. At the tenth leaf stage: leaves elliptic to elliptic-obovate, apex acuminate, base cuneate or obtuse, upper surface glabrous; very small oil dots just visible with a lens. Petioles transversely wrinkled, hairy. Seed germination time 54 to 109 days.
