Abstract:
Abstract- A cladistic analysis of the "blue ash" eucalypts (Eucalyptus, Myrtaceae) is presented. Five equally parsimonious trees were found, and a strict consensus tree constructed. A revised informal classification, recognizing five series (Planchonianinae, Sphaerocarpinae, Piperitinae, Fraxininae and Haemastominae, informal subgenus Monocalyptus) is based on the consensus cladogram. A biogeographic analysis applies a new implementation of Assumptions 0 and 1, coding data in the form of three-area statements and using parsimony analysis. These results are used to evaluate hand resolution of Assumption 2. In comparison, Brooks parsimony analysis did not produce area cladograms that best fit the data. Series and subseries were analysed separately for area relationships, which showed a repeated pattern across the blue ash clade; combining all the data in one analysis was seen as equivalent to confounding paralogy and orthology in molecular studies. A resolved area cladogram is presented for southeastern Australia.
