Lythraceae

Flowers of Nesaea luederitzii var. luederitzii, photographed by A. A. Dreyer.


Belongs within: Myrtales.

The Lythraceae is a morphologically diverse family of plants. Economically significant members include the pomegranate Punica granatum and the water chestnut Trapa natans.

Characters (from Qin, Graham & Gilbert): Herbs, shrubs, or trees; young stems often quadrangular. Leaves opposite, often decussate, or whorled, rarely subalternate to alternate, simple, entire; pinnately veined, secondary veins typically joined in a series of intramarginal arches; stipules vestigial or absent. Inflorescences racemes, cymes, or panicles; flowers axillary or terminal, usually 4-, 6- or 8-merous, sometimes 3- or 5-merous, bisexual, regular or irregular. Floral tube perigynous, hemi-epigynous, or epigynous, persistent in fruit, membranous to leathery, often 6-12-ribbed; sepals valvate, equal to much shorter than floral tube, membranous to thickly leathery, persistent; epicalyx alternating with sepals or absent. Petals inserted at rim of floral tube, alternating with sepals, crinkled, clawed or not, frequently caducous, rarely absent. Stamens usually biseriate and 2 × as many as sepals, sometimes uniseriate, inserted near base of floral tube or higher, or numerous, multiseriate, with at least some inserted at floral rim just below sepals (Punica, Sonneratia and some Duabanga); anthers versatile (rarely basifixed). Ovary superior, half-inferior, or inferior, 2-6- or multi-loculed, with many ovules per locule; style simple; stigma capitate, conic-peltate, or punctiform; placentation axile, sometimes free central at fruit maturity. Fruit partly or completely surrounded by persistent floral tube, loculicidally dehiscent or irregularly dehiscent capsules, infrequently indehiscent, leathery, or berrylike. Seeds usually numerous, without endosperm; embryo straight, cotyledons flat or convolute.
