Radlkofer, L.A.T. (1879) Sitzungsberichte der Mathematisch-Physikalischen Classe der k. b. Akademie der Wissenschaften zu M~ynchen 9 : 525. Type: Queensland, Rockingham Bay, J. Dallachy; lecto: MEL.


A small tree not exceeding 30 cm dbh. A thin, brown layer normally present beneath the subrhytidome layer before the first section of the outer blaze.


Compound leaves usually with two leaflets, each leaflet blade about 3.5-11 x 1-3.2 cm. Lateral veins forming loops just inside the blade margin and midrib raised on the upper surface. Leaflet stalks very short and swollen at their junction with the compound leaf petiole and rhachis.


Inflorescence about 5-8.5 cm long, pedicels about 2-3 mm long. Calyx about 2.5-3 mm long, puberulent, lobes ovate-triangular. Petals broadly obovate, usually 2-toothed, clawed, about 1.2-1.5 mm long, densely villous. Stamens usually eight, filaments hairy, about 3 mm long, inserted inside the disk.


Fruits very glossy, wax-like, obovoid, about 10-12 mm long, usually one or 2-seeded. Valves villous on the inner surface. Aril annular, confined to the base of the seed. Seeds +/- ovoid or ellipsoid, about 8-10 x 7-8 mm.


First pair of leaves simple and ovate or trifoliolate with elliptic or ovate leaflets or simple and deeply 3-lobed. At the tenth leaf stage: leaf blade elliptic or narrowly elliptic, apex acuminate, base attenuate, glabrous; petiole with a few, pale, prostrate hairs. Seed germination time 14 to 27 days.
