Maximum likelihood phylogeny of ETS as calculated in RaXML, showing the Lepidium oleraceum (black text) and Lepidium sisymbrioides (red text) groups, including the newly described taxa. Bootstrap support from 1000 replicates is shown for branches where it is greater than 50. Codes for each individual in the phylogeny are shown in Table 1. The main clade branches have been truncated to accommodate the tree within the journal format. AUS = Australia, NZ = New Zealand.
