    Herbs, much branched, forming tangled or spreading masses. Stems with branches divaricate or ascending, terete or obtusely angled, 2-10(-15) dm, sparsely scurfy when young. Leaves alternate (or the proximalmost opposite), long petiolate becoming nearly sessile distally, blade ovate to triangular, 15-50(-60) × 10-40 mm, base subhastate or cuneate, margin deeply or shallowly sinuate-dentate with acute or obtuse teeth, apex acute or obtuse, distalmost bracteate blades becoming entire and linear or oblong-linear. Staminate flowers in glomerules borne in slender, naked or sparingly bracteate (at base), mostly interrupted simple or paniculate spikes, calyx 5-cleft. Pistillate flowers fascicled in distal axils. Fruiting bracteoles strongly 3-veined and reticulate, sessile or short stipitate, ovate-rhombic or subflabelliform, 4-8 × 3-7 mm, moderately compressed, united from narrowed base to middle, margin broad, foliaceous, coarsely dentate, indurate at maturity, faces tuberculate or smooth.
