General Information

Herbs annual or perennial, armed with stinging hairs. Stems sympodial, upper stem often zigzig, often 5-angled. Leaves alternate, petiolate; stipules caducous, intrapetiolar, connate, often broad, foliaceous; leaf blade 3-veined, margin dentate or lobed; cystoliths punctiform. Inflorescences in axillary pairs or solitary, cymes, panicles or spikes, unisexual (plants monoecious or dioecious); male inflorescence often long, flowers clustered on rachis of spikes, dichotomous cymes, or panicles; female glomerules lax or dense on rachis of scorpioid cymes, spikes, or panicles. Male flowers: perianth lobes 4 or 5, valvate; filaments inflexed in bud; rudimentary ovary conspicuous. Female flowers: perianth lobes 4, 2 or 3 lobes connate into a tube, 2 or 3-toothed, split to base on 1 side, sometimes also with a small bristle-like segment; staminodes absent. Ovary straight, ovoid; stigma subulate, papillose on 1 side; ovule orthotropous. Achene often large, slightly oblique, often compressed, verrucose; persistent stigma usually reflexed; pedicels simple or swollen. Seeds with thin or no endosperm; cotyledons broad.
