Herbs, subshrubs, or shrubs, perennial, rhizomatous, without stinging hairs, sparsely to ± densely pubescent or tomentose with hooked, curved, or straight, nonstinging hairs on all parts of plant. Stems simple to freely branched, erect. Leaves opposite or nearly opposite, or alternate; stipules present. Leaf blades lanceolate to broadly ovate, base rounded to cordate, less often cuneate, margins dentate or serrate, apex acuminate; cystoliths rounded. Inflorescences axillary, spikelike or paniculate.
