Leaves ovate, up to 45(-80) x 25(-45) mm, apex acute or acuminate, base cuneate, margin serrate with 3-12 pairs of teeth, upper surface with scattered stiff hairs above, lower surface with stiff hairs on veins or sometimes also scattered; petiole up to 20(-45) mm long, with indumentum as in branches; stipules lanceolate, apex acuminate, up to 3 mm long, midrib brown and prominent, membranous. Inflorescences in upper axils consisting of clusters of bisexual, female or mixed inflorescences, in lower axils often only female inflorescences, bisexual inflorescences up to 4 mm in diameter. Flowers as for genus. Achenes enclosed in persistent, glabrous or lanate involucre.
Perennial herb, monoecious, 0.1-1.5 m high. Leaves mostly opposite, ovate to lanceolate, toothed, up to 60 x 25 mm, upper surface slightly hispid, lower surface with soft hairs, apex acuminate, margins serrate; petioles pubescent, up to 25 mm long; stipules lanceolate to ovate, with elongated tip, up to 3 mm long. Inflorescence 2 or 3 clustered in upper axils, usually bisexual, up to 4 mm in diam., in lower axils often only female flowers. Flowers in small axillary clusters, bisexual, greenish. Male flowers many, up to 2 mm long. Female flowers few; ovary erect, up to 1.5 mm long; stigma up to 3 mm long. Flowering time Aug.-Feb. Fruit a compressed, brownish achene, up to 1.5 mm long.
Inflorescences variable, typically consisting of two bisexual involucres (containing male and female flowers) and a reduced branch with few-many female involucres (each containing 1(2) female flowers) in each leaf axil, but any of these elements maybe missing. Both types of inflorescence maybe found on different plants or on the same plant.
Bisexual involucres 4–6 mm. in diam., mostly with many male flowers and a few naked female flowers; male flowers up to c. 2 mm. long. Female involucres often many together, perianth-like, each usually with 1(2) female flowers, up to 1.5 mm. long.
Monoecious, softly woody perennial, mostly to 50 cm. Leaves mostly opposite, lanceolate, toothed, apical tooth longer than wide, with tailed apices. Flowers in small, axillary clusters, greenish.
