A family of herbs, shrubs, and trees that have regular penta- or tetramerous flowers and the same number of sepals, petals, and stamens. The ovary is 3–5-celled, the fruit a capsule. They are cultivated for flowers or useful products (e.g. Linum species yield flax and linseed oil). Modern classifications recognize some 300 species, within 15 genera.
