The Rutaceae is better known to most people as the citrus family. It belongs to a larger group, order Sapindales, which includes soapberries, sumacs, maples, horse-chestnuts, both frankincense and myrhh, and mahoganies. Members of the Rutaceae can be herbs, shrubs or trees, and often have flowers or leaves with strong scents. The genus Citrus is the most important economically, but there are non-citrus fruits such as the white sapote. Other family members are used for medicinal purposes and in the perfume industry. The family contains about 160 genera and approximately 1600 species. Spines are typical in this family, and the flowers are most often pollinated by insects. This is a very widespread family, including temperate, tropical and sub-tropical regions with most genera in southern Africa and Australia.
