Information

Herbs, sometimes somewhat suffruticose, with a woody, ± creeping rhizome and rooting at the lower nodes; stems often reddish. Leaves opposite, verticillate or alternate, generally small, sessile or shortly petiolate, the limb entire or lobed. Inflorescences axillary 1–11-flowered fascicles, sometimes of 1–3 pedicellate hermaphrodite flowers and the others ♀ and sessile or subsessile, or sometimes 1 long-pedicellate ♂ flower and the others ♀ and sessile or subsessile, or sometimes long-pedicellate ♂ flowers in the axils of the upper leaves and ♀ sessile or subsessile flowers in the axils of the lower leaves. Flowers with calyx-tube ellipsoid or urceolate, with longitudinal nerves and also longitudinal often strongly mamillate ribs; calyx-lobes 4, persistent; petals 4, sometimes rudimentary or lacking in female flowers; stamens 4 or 8; ovary 4-locular, becoming 1-locular through the dissolution of the septa; ovules 4; styles 4 or absent; stigmas plumose. Nutlets very small, ribbed or not. Seed 1, pendulous.
