Description:
Climbing perennial herb with stinging hairs. Stems up to 3 m long, growing from a woody rootstock, sparsely hairy to almost hairless. Leaves triangular-lanceolate to linear-lanceolate, up to c. 12 cm long, cordate at the 5-7-veined base, often hastate with 2 rounded lobes, sparsely hairy to almost hairless on both surfaces, sometimes bristly on the midrib and veins below; margin sharply dentate. Inflorescences terminal or leaf-opposed, up to 15 cm long on a peduncle up to 15 cm long. Flowers unisexual on the same inflorescence. Calyx of the female flowers densely covered in stiff hairs, consisting of 3 lobes; each lobe palmately divided into 11-13 linear lobes again (see image 3).
