A family of herbs or low shrubs, rarely tree-like, that have alternate lobed or compound stipulate leaves. The flowers are regular, usually pentamerous with free petals and sepals, and usually with twice as many stamens as petals, a superior 3–5-celled ovary, and usually a long beak bearing the free stigmas. The fruit is a lobed capsule, the lobes usually 1-seeded, sometimes separating. There are 14 genera, with about 730 species, in temperate and tropical zones. Garden ‘geraniums’ are varieties of Pelargonium species from S. Africa, with slightly irregular, spurred flowers.
