Annual, perennial herb, shrub, tree.
Stem: 4-angled or cylindric.
Leaf: simple, entire, generally opposite, 4-ranked ( alternate, whorled).
Inflorescence: flowers terminal or in axils of upper leaves or leaf-like bracts, 1 or in ± dense cymes or along short shoots, sessile or not, subtended by 2 bractlets.
Flower: bisexual, generally radial; hypanthium bell-shaped to cylindric, membranous or leathery, persistent in fruit; sepals appearing as hypanthium lobes, 4–9, epicalyx lobes alternate sepals or 0; petals, stamens inserted on inner hypanthium; petals 4–6 or 0, alternate sepals, crinkled, deciduous; stamens generally = or 2 × sepals, included or exserted; ovary generally superior, chambers 2–6[many], style generally slender, stigma head-like.
Fruit: dry capsule or leathery berry, dehiscent into 2–4 valves or irregularly.
± 28 genera, 600 species: temperate, tropics, generally in wet habitats. Some ornamental or cultivated for medicine, dyes. [Graham et al. 2005 Int J Plant Sci 166:995–1017] "Epicalyx lobes" (lobes on calyx) formerly called "appendages"; "hypanthium" in Lythraceae (and Onagraceae) including receptacle, sometimes called "flower cup" or "flower tube". Punicaceae (Punica) included here. —Scientific Editor: Thomas J. Rosatti.
