White, C.T. (1933) Contributions from the Arnold Arboretum of Harvard University 4: 92. Type: Queensland, Boonjie, 30 Sept. 1929, S. F. Kajewski 1347; holo: BRI, iso: A, NSW.
A slender vine not attaining a stem diameter greater than 2 cm.
Leaf blades about 10-20 x 5-9 cm, petioles about 2-6 cm long. Lateral veins about 5-7 on each side of the midrib. Upper and lower leaf blade surfaces clothed in short erect translucent, pale brown or ginger hairs. Small glands resembling tiny stipules, about 1.5 mm long, visible on the twigs between the petiole bases. Twigs and petioles densely clothed in brown hairs.
Inflorescence about 5 cm diam. with three main branches in the panicle. Flowers about 10-12 mm diam. Calyx lobes about 6 mm long, both surfaces clothed in hairs. Corolla tube about 2 mm long, densely clothed in white hairs on both the inner and outer surfaces, lobes about 5-6 mm long. Anthers about 4 mm long, connate at the apices, each anther with two tails at the base. Nectary scales surrounding the base of the ovary, each about 2 mm long and bifid at the apex. Ovary densely hairy. Style and/or stigma about 2-5 mm long, fused to the anthers. Ovules numerous in each locule.
Fruits about 20-22 x 1.8 cm, densely clothed in short, velvety, golden-brown hairs. Calyx persistent at the base. Seeds numerous, each seed about 1.5-2 x 0.3-0.4 cm, angular, plumed at one end, plumes about 3-6 cm long. Cotyledons V-shaped in transverse section. Radicle about 3-5 mm long, shorter and narrower than the cotyledons which are up to 9 mm long.
Cotyledons ovate to cordate, about 22-39 x 18-25 mm, 3-veined at the base, lateral veins forming loops inside the margins, upper and lower surfaces sparsely clothed in hairs. First leaves ovate to elliptic, upper and lower surfaces hairy. At the tenth leaf stage: plants twining, all parts clothed in short soft hairs. Glands about 1 mm long and resembling stipules visible on the stems between the petiole bases. Leaf blade elliptic to obovate, apex acuminate, base obtuse. Midrib raised on the upper surface of the leaf blade.
