|definition||Distribution: This family consists of c. 155 genera and 1600 species and have a nearly
cosmopolitan distribution, but are mainly tropical and subtropical. In Australia and
southern Africa this family is especially abundant. In Australia there are 43 genera
(24 endemic) and 486 species (458 endemic).
Description: The species in this family are shrubs or trees or sometimes herbs, sometimes scrambling or scandent, sometimes armed, with pellucid glands containing aromatic, volatile oil visible from surface of at least the leaves, young branchlets, inflorescences, flower parts, pericarp, or cotyledons in seed.

Pollen Morphology: The pollen produced by this family is diverse, however most Australian native Rutaceae are tricolporate grains elongated into a long oval along the equatorial axis. However, some Rutaceae species have pollen that is closer to a rounded triangle. The size of these grains are variable depending on the taxon but are mostly medium to large (40um). The majority of the taxa are tricolporate, with a large round pore in the centre of the colpus. In many taxa the membrane protrudes markedly from the pore. The surface texture of these grains is roughly granular.
