Rutaceae - Flora of Australia

Dr Marco Duretto - Manager Plant Diversity

Rutaceae - An important role of herbaria is to summarise current knowledge of groups of plants into accounts for world, national and state floras. These accounts provide identification tools, descriptions and illustrations and are often the only available resource that brings together the dispersed scientific literature of a group. They are invaluable for a wide range of researchers, land managers, students, and those interested in the flora.

Volume 26 of the Flora of Australia (Australian Biological Resources Study (ABRS) was published in May 2013. This volume included three plant families: Meliaceae (13 genera, 44 spp.), Rutaceae (43 genera, 486 spp.) and Zygophyllaceae (5 genera, 58 spp.). With more than 600 pages the volume is one of the largest yet published for this series.

Rutaceae is a Southern Hemisphere family that is well represented in Australia (43 genera, 24 endemic; 486 spp.,
458 endemic) being found in a diversity of habitats that include coastal heath, semi-arid woodland, tropical to temperate rainforest, and alpine heath and herbfields. The written account for Rutaceae in the Flora of Australia was completed by nine authors including two Trust staff, Marco Duretto and David Mabberley. Trust botanical artists, Lesley Elkan and Catherine Wardrop, contributed several outstanding plates illustrating species in various genera. For Rutaceae, almost one half of the taxa in the Flora belong to the two largest genera, Boronia and Zieria (Duretto et al. 2013; Duretto 2013; George et al. 2013).

Boronia is a large Australian genus of c. 150 species distributed in all states and mainland territories. It is particularly diverse in south-west Western Australia and eastern Australia with minor centres of diversity in the Top End of the Northern Territory and the Kimberley. The Flora of Australia account (Duretto et al. 2013) of Boronia is the first full account of the genus for more than 80 years. There are six sections and the complicated history of ABRS funding has meant that the sectional accounts are varied in their authorship. The three larger sections have infrageneric classifications and in this volume the first formal infragenericclassification was described for section Cyanothamnus (Duretto 2013). There is an ongoing research program at the Trust investigating the infrageneric and species relationships of Boronia and the related genus Boronella.
