|The Lythraceae are mostly tropical herbs or occasionally shrubs or trees comprising about 24 genera and 500 species. The leaves are simple, usually opposite or whorled; stipules are minute or absent. The flowers are strongly perigynous, actinomorphic or sometimes zygomorphic, commonly 4-,6-, or 8-merous. The sepals appear as lobes of the perigynous zone, the petals are distinct and usually crumpled. The stamens commonly are twice the number of petals, and are usually in two whorls, one with the filaments longer than the other. The gynoecium consists of a single compound pistil of usually 2-4 carpels, a single style and stigma, and a superior ovary with usually 2-4 locules, each with numerous axile ovules. The fruit is commonly capsular.
