(Return to Family List)

The Geraniaceae is a widespread family, especially in the temperate and subtropical regions of the world. It is economically important mostly for ornamentals (Geranium, Pelargonium, and Erodium) but also for geranium oil used in perfumes that is distilled from the leaves of species of Pelargonium (e.g., "lemon-scented geranium").

The Geraniaceae are generally herbaceous plants with jointed stems and alternate, opposite, or basal simple, palmately- (or pinnately-) lobed leaves. Most have simple gland-headed hairs with aromatic oils. Stipules are usually present. The most distinctive character is the prominent, beak-like sterile column around which the 5 carpels are joined. As the fruit matures, this column, as well as the carpels, expand to form the "crane's bill" characteristic of the family. The flowers are generally pink-purple, with 5 distinct petals, 5 distinct sepals, and 10-15 stamens.
