We gathered morphological data and genome‐wide single nucleotide polymorphisms to infer the evolutionary relationships of Xerochrysum, Coronidium, and Helichrysum leucopsideum, and to test the circumscription of the genera. SVDquartets species tree topology resolved relationships between the genera and within subsets of the Xerochrysumdata. Results corroborated previous conclusions that Coronidiumis non‐monophyletic as presently circumscribed and forms, in addition to the more distantly related Coronidium scorpioidesgroup, three morphologically distinct clades. SVDquartets returned two clades in Xerochrysum, though species‐level relationships were unclear. Bayesian coalescent analysis using SNAPP produced tree topologies for the three clades of Coronidiumwith most species‐level relationships well resolved. The new genus Leucozomais described for seven taxa previously included in Coronidium.A revised description of Coronidiumand images of phyllary and fruit diagnostic morphological characters are provided. |
