Detailed description
A deciduous woody climber or scrambler with weakly ribbed cylindrical stems. Opposite leaves; hairless to sparsely hairy, and can be coated with a readily removed fine whitish bloom. Leaves are usually 8-15cm long and 7-12cm wide. Leaflets are thin, lanceoloate in shape with sharply toothed margins. The leaf stalks are 4-8 cm long, hairless or with fine silky hairs present. The green-yellow flowers hang down, and occur solitary in leaf axils. The 4 conspicuous sepals are hairless on the outside but have silky hairs on the inside and dense hairs near margins; 13-19 x 5-8 mm, lanceolate in shape. Anthers are 3-4 mm long. Seed heads develop January-April, persisting through the winter as yellowish green fluffy balls. The achenes are compressed and hairy (c. 4mm long), with a 3-4.5cm long feathery style.
