Integrating phylogenomics and taxonomy – resolving the complex evolution of the Donkey Orchids (Diuris) for the Flora of Australia (Old ID 24704)

Role

Chief Investigator

Description

This study aims to unravel the complex relationships in the Australian orchid genus Diuris for a well-founded treatment in the Flora of Australia. Evolutionary relationships of Diuris will be reconstructed at subgeneric, sectional and interspecific levels based on data set from the plastid and nuclear genomes. Population genomic analysis of two species complexes will allow for clarifying species delimitations and re-assessing the conservation status of threatened Diuris species. The taxonomic utility of morphological characters will be evaluated and improved identification keys and revised taxonomic concepts for Diuris generated for a revised treatment of the genus in the Flora of Australia.
