A slender vine not exceeding a stem diameter of 2 cm.
Leaf blades about 7-12 x 6-12 cm, petioles about 4-8 cm long. Underside of the leaf blade much paler than the upper surface and densely clothed in pale hairs.
Inflorescence up to 10-13 cm long, hairy, a raceme of fascicles. Bracts large and conspicuous particularly towards the base of the inflorescence where they may be about 2 x 2 cm, while further up the inflorescence they are smaller. Male flowers: Flowers about 1-2 mm diam. Sepals obovate, about 1-2 mm long. Petals fused to form a cup-shaped corolla about 0.25-0.5 mm high. Anthers about 0.25 mm wide, fused together to form a staminal column. Female flowers: Each fascicle of flowers subtended by a large cordate, leaf-like bract up to 14 x 20 mm. Pedicels about 2 mm long. Sepals broadly obovate, about 1.5 x 1 mm. Petals broadly cuneate-obovate, about 1 x 1 mm. Ovaries (carpels) hairy, about 0.75 mm long. Stigma 3-lobed. Ovules 2.
Fruits globose or slightly laterally compressed, about 6 mm diam., densely clothed in short hairs. Fruits red when fully ripe. Seeds +/- horseshoe-shaped, about 4 mm diam., testa surface sculptured. Embryo U-shaped or horseshoe-shaped. Cotyledons about one third the total length of the embryo. Cotyledons about 2.5 mm long. Radicle about 5.5 mm long.
Cotyledons linear, about 10-15 x 1-2 mm, sessile. First pair of leaves ovate, triangular or cordate, often slightly peltate, petiole hairy. At the tenth leaf stage: leaf blade +/- cordate, peltate, venation palmate. Underside of the leaf blade clothed in pale prostrate hairs. Midrib slightly raised on the upper surface of the leaf blade. Terminal bud and stem clothed in pale +/- prostrate hairs. Seed germination time 136 to 167 days.
This species may have medicinal properties. It is thought to be a good diuretic.
