Female flowers: pedicels less than 1 mm long, extending to 2–3 mm long in fruit; calyx lobes 6, unequal, 1.5 × 1–1.5 mm, with 2 being broader than the other 4, accrescent to 4.5–6 × 2–3 mm, each lobe (7)9–13-lobulate, the lobules linear to linear-lanceolate, longer than or equalling or shorter than the width of the calyx-lobe rhachis, sparingly pubescent and/or shortly setose, green, the calyx-lobe rhachis loriform or elliptic-lanceolate, sparingly puberulous to subglabrous without, glabrous within, becoming hardened and stramineous proximally, remaining ± herbaceous distally; ovary 1–1.5 mm in diameter, 3-lobed, densely setose; styles 3, 2–3 mm long, extending to 4–5 mm long, ± erect, slightly divergent, connate for one-third of their length, later for almost three-quarters of their length by the extension of the column, subglabrous; stigmas minutely verruculose, recurved at the tips.
Leaf blade 4–12 × 1–2.5 cm, narrowly triangular-lanceolate to elliptic-lanceolate, acute or subacute at the apex, serrate to denticulate on the margins, rounded or cuneate at the base, thinly chartaceous, 3(5)-nerved from the base, with the inner pair of nerves often running more than halfway up the blade, sparingly pubescent and also hirsute and setose along the midrib and main nerves on both surfaces; tertiary nerves reticulate; lateral nerves in 3–7 pairs, scarcely prominent above, fairly prominent beneath.
Inflorescences up to 11 cm long, with a peduncle up to 6 cm long, either terminal on the main stem and/or on the axillary leafy shoots or else leaf-opposed, bisexual, mostly male with 1–3 female flowers at the base; male bracts 2 mm long, lanceolate, ciliate; male bracteoles 1–1.5 mm long, linear; female bracts c. 3 mm long, lanceolate to ovate-lanceolate, sometimes 3-dentate to 3-fid; female bracteoles resembling the male bracts, but slightly larger.
Male flowers: pedicels 1.5–2 mm long; buds ellipsoid-subglobose; calyx lobes 1.5 × 1 mm, elliptic-ovate, acute, cucullate, glabrous, yellow-green; stamens c. 1 mm long; pistillode 3-lobed, the lobes truncate.
Seeds 4 mm in diameter, globose, greyish-buff, closely flecked and blotched with dark purplish-brown, and with scattered circular patches fringed with whitish papillae.
Erect sparingly branched urticating perennial herb 40–50(80) cm tall, monoecious; stems 1 or more from a woody rootstock, pubescent.
Stipules 4 mm long, lanceolate, ciliate, otherwise subglabrous, erect or spreading.
