    An erect, simple-stemmed or sparingly branched dioecious villous urticating perennial herb up to 5.5 dm. with a woody rootstock.
    Leaves
    Petiole 5–8 mm. long, densely villous; blade ovate, (3–)5–8 cm. long, (2.5–)3–5.5 cm. wide, acute, subacute or obtuse, widely and fairly shallowly cordate, crenate-serrate, firmly membranaceous, 7(–9)-nerved from the base, lateral nerves 4–5 pairs, densely villous above and beneath at first, later evenly to sparingly so, and with stinging hairs scattered along the midrib and main nerves, bright green.
    Stipules
    Stipules lanceolate at the lower nodes, more narrowly lan-ceolate at the upper, 5–7 mm. long, 1–2 mm. wide, acute, abaxially villous-pubescent, adaxially glabrous.
    Inflorescences
    Inflorescences terminal, on the main stem or lateral shoots. Female inflorescences 3–5 cm. long, densely flowered and subcapitate; axis and bracts ± as in the ♂ inflorescences. Male inflorescences 5–7(–10) cm. long, interruptedly flowered, the flowers disposed in 3-flowered cymules along the axis; axis densely villous; bracts and bracteoles shorter than but otherwise resembling the stipules.

Male inflorescences 5–7(–10) cm. long, interruptedly flowered, the flowers disposed in 3-flowered cymules along the axis; axis densely villous; bracts and bracteoles shorter than but otherwise resembling the stipules.
    Flowers
    Female flowers:pedicels 1.5 mm. long, densely villous; calyx-lobes 6, elliptic-lanceolate in outline, 3 mm. long, extending to 2 cm. long in fruit, the rhachis narrowly lanceolate, pinnately lobulate, with 10–12 linear lobules on each side, acute, the rhachis and lobules densely beset with whitish or stramineous urticating bristles; ovary trilobate, 2–3 mm. diameter, densely setose; styles 3, 6–7 mm. long, united for ± one-third their length, pubescent without, the stigmatic surfaces ± smooth. Male flowers:pedicels 1 mm. long, evenly hirsute; calyx-lobes 3, ovate-lanceolate, 2 mm. long, 1 mm. wide, acute, evenly hirsute without, glabrous within, cream-coloured; stamens 1.5 mm. long, filaments slender, anthers 0.8 mm. long; pistillode minute, trilobate.
    Female
    Female flowers:pedicels 1.5 mm. long, densely villous; calyx-lobes 6, elliptic-lanceolate in outline, 3 mm. long, extending to 2 cm. long in fruit, the rhachis narrowly lanceolate, pinnately lobulate, with 10–12 linear lobules on each side, acute, the rhachis and lobules densely beset with whitish or stramineous urticating bristles; ovary trilobate, 2–3 mm. diameter, densely setose; styles 3, 6–7 mm. long, united for ± one-third their length, pubescent without, the stigmatic surfaces ± smooth. Female inflorescences 3–5 cm. long, densely flowered and subcapitate; axis and bracts ± as in the ♂ inflorescences.
    Fruits
    Fruits strongly trilobate, 4.5 mm. long, 8 mm. diameter, verrucose, evenly to densely setose.
