Stem

Usually flowers and fruits as a slender vine. Vine stem diameters to 3 cm recorded. Blaze darkens on exposure. Bark included in the wood as rays which extend from the pith to the outer edge of the stem.

Leaves

Leaf blades about 6-13 x 2.5-4.5 cm, petioles about 0.4-1.2 cm long. Lateral veins about 5-7 on each side of the midrib, forming definite loops well inside the blade margin. Marginal teeth 1-6 on each side, small and inconspicuous. Petiole bases +/- joined by a ridge of tissue across the twig. Twigs very pithy in transverse section, vascular bundles forming a ring around the margin are just visible inside the cambium layer.

Flowers

Flowers +/- fan-shaped, about 15-17 mm diam. Calyx tube (hypanthium) about 5 mm long. Calyx lobes about 1.5-3 mm long. Corolla about 25 mm long, lobes about 7-8 mm long, the tube split along the upper surface so that the corolla opens out and is +/- flat and densely clothed in pale brown hairs. Stamens about 11-12 mm long. Style about 12-14 mm long, expanded to form a hairy cup-shaped structure at the apex. Ovules one per locule.

Fruit

Fruits ovoid to ellipsoid, about 9 x 7 mm, calyx lobes persistent at the apex. Endocarps about 7 x 3 mm, surface rugose. Seeds usually 2 per endocarp. Cotyledons about 2-2.5 mm long, wider than the radicle.

Seedlings

Cotyledons elliptic, about 13-14 x 7 mm, venation obscure. Upper and lower surfaces densely clothed in short, translucent hairs. Margins ciliate, hypocotyl hairy. First leaf blades +/- elliptic to ovate, apex apiculate, base cuneate, margin with 3-5 teeth on each side, both the upper and lower leaf blade surfaces hairy.
