Herbs, shrubs, or trees: leaves usually opposite or whorled: flowers bisexual, usually regular, perigynous; receptacle (“calyx-tube”) tubular, ribbed, free from the ovary, bearing the 4 or 8 valvate sepals on its margin; petals of the same number as the sepals, or 0, and inserted with them, imbricated; stamens usually twice as many as the petals, rarely more (up to 200), or fewer (to 1); outer set alternate with the petals, and inserted some distance below them; ovary superior, 2-6-celled, many-ovuled: fruit a capsule, rarely indehiscent.

Lythrum Salicaria has been used as an astringent: Heimia and Cuphea have been used as purgatives and emetics. Lawsonia inermis of Egypt is the famous henna, the perfume of the flower of which is renowned throughout the East; with an orange-red dye obtained from the leaves of this plant, women of the orient dye hair and nails. Pemphis acidula is used as a pot-herb in Asia. The flowers of Woodfordia floribunda yield the red dye of India called dhak. Lagerstroemia furnishes very valuable timber.

In cultivation in N. America are several genera: Cuphea, species of garden annuals; Decodon (Swamp Loosestrife), native, but used for water-gardens; Lythrum (Loosestrife); Lawsonia (Henna), cultivated in southern Florida and southern California; Lagerstroemia indica (Crape Myrtle) cultivated in the South.
