Perennial, canescent. Stems suberect to decumbent, usually under 50 cm long, angular-sulcate, often very woody and grey to white at the base, the younger parts shortly and usually sparsely hispid or setose-scabrid on the angles. Leaves canescent, as a rule suborbicular-cordate or reniform-cordate, sometimes faintly 5-angled rarely very indistinctly 5-lobed, rounded at the apex or shortly and abruptly apiculate, deeply cordate at the base, firm and rather thick in texture, usually distinctly crenate-dentate along the margin, on both surfaces at first rather densely and shortly setose-strigose, glabrescent, but veins on lower surface persistently setulose-hispid, blade usually under 5 cm long and broad; petioles shortly hispid or setose, rarely over 5 cm long. Tendrils usually short or more or less reduced, shortly and sparsely hispid. Flowers monoecious. Male flowers solitary or in fascicles of 2-3; pedicels slender to filiform, finely setulose, 2-10 mm long; receptacle more or less densely setulose to sericeo-setulose, 4-6 mm long; sepals erect, subulate, 1.5-2 mm long; corolla bright light yellow, finely hairy, 5-7 mm long. Female flowers solitary on 3-12 mm long pedicels, ovary ovoid-globose to oblong, densely covered with rather long stiff, white hairs. Fruit subglobose when ripe, smooth, glabrous, yellow to orange and concolorous, 2-3.5 cm long and 2-3 cm in diam. Seeds obovate with narrow base and rounded to subacute apex, 4-4.5 mm long and about 2.5 mm broad.
