Lateral veins 5-7 on each side of the midrib. Stipules +/- elliptic, about 5 mm long. Tendrils simple (unbranched) leaf-opposed. Twigs terete, green and glabrous, circular in transverse section, showing an oak grain. Scattered, shallow, pit-like glands present on both the upper and lower surfaces of the leaf blade.
Inflorescence leaf-opposed. Flowers about 4-5 mm diam. Calyx cup-shaped, about 0.8 mm high, lobes absent. Receptacle about 2-2.5 mm diam. Petals about 2-3.5 mm long, hooked at the apex, reflexed at anthesis. Staminal filaments about 1.3-2.5 mm long, attached outside the disk. Anthers about 1 mm long. Disk pale-coloured, white to green, surface undulate. Ovules 2 per locule.

Stipules triangular, about 2 mm long. First pair of leaf blades ovate to cordate, apex acuminate, base truncate to somewhat cuneate, about 28-33 x 20-22 mm, margins toothed, petioles about 12-15 mm long. Hypocotyl glabrous. At the tenth leaf stage: leaf blade cordate to ovate, apex acuminate and mucronate, base shallowly cordate, margin with about 15-19 teethed on each side, teeth serrulate. Midrib and lateral veins raised on the upper surface. Minute 'oil dots' barely visible with a lens. Stipules caducous, apex obtuse, about 3-4 mm long. Tendrils simple (unbranched) leaf-opposed.
