In Australia and southern Africa this family is especially abundant. In Australia there are 43 genera (24 endemic) and 486 species (458 endemic).

For more details regarding the description of species within this family please see:

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.
