Slender twiner, stems ascending, to 2 m long or more, glabrous or with scattered papillae or tubercles. Leaves ovate to triangular, 2–8 cm long, 10–40 mm wide, apex acuminate, base more or less sagittate, margins finely and irregularly crisped; petioles often subequal to blade. Flowers in small clusters within very slender, interrupted, spike-like or commonly branched inflorescences 5–15 cm long, pedicels mostly shortly exceeding the subtending bract; perianth segments free almost to base, yellow-green, 1–2 mm long, slightly longer in fruit in female flowers but remaining membranous. Nut broadly ovoid, 2–2.5 mm long, obscurely 3-ribbed, finely wrinkled or warted, black. Flowers mostly Nov.–Mar.

EGL. Also Qld, NSW. Extremely rare in Victoria, and believed to be extinct, but rediscovered in 2002, at or near its last known (1938) site in Victoria, from sandy alluvium in riparian forest along the Cann River. It has since been incorporated into revegetation projects along lower reaches of some East Gippsland (e.g. Genoa, Cann) rivers, so obscuring its natural occurrence, but possibly reinstating it to previous unknown sites of occurrence.
