Description
Table 6. An overview of the three possible classification schemes for the E. odorata complex outlined on the basis of the findings of the phylogenetic study present here.
| Current taxon | Morphology-driven classification | Hybrid classification | Strict phylogenetic classification |
|---|---|---|---|
| E. viridis | E. viridis | E. viridis | E. viridis |
| E. aenea | E. aenea | E. aenea /= E. viridis | = E. viridis |
| E. castrensis | Potential mixed hybrid population – further sampling needed | Potential mixed hybrid population – further sampling needed | Potential mixed hybrid population – further sampling needed |
| E. viridis var. latiuscula | Potential new taxon – further sampling needed | Potential new taxon – further sampling needed | Potential new taxon – further sampling needed |
| E. odorata | E. odorata (distribution reduced to west of Murray Basin and south of the Flinders Ranges) | E. odorata (distribution reduced to west of Murray Basin and south of the Flinders Ranges) | E. odorata |
| E. cajuputea | E. cajuputea (distribution reduced to only Flinders Ranges) | E. cajuputea (distribution reduced to only Flinders Ranges) | = E. odorata |
| E. polybractea | E. polybractea (distribution reduced to only central Victoria and West Wyalong | E. polybractea (distribution reduced to only central Victoria and West Wyalong | E. polybractea (distribution reduced to only central Victoria and West Wyalong region |
| region of NSW, populations of E. polybractea subsp. subcerea of uncertain classification between E. polybractea and E. wimmerensis) | region of NSW, populations of E. polybractea subsp. subcerea of uncertain classification between E. polybractea and E. wimmerensis) | of NSW, populations of E. polybractea subsp. subcerea of uncertain classification between E. polybractea and E. wimmerensis) | |
| E. filiformis | E. filiformis | = E. polybractea | = E. polybractea |
| E. yarriambiack | E. yarriambiack | E. yarriambiack | = E. polybractea |
| E. wimmerensis | E. wimmerensis | E. wimmerensis | E. wimmerensis |
| E. walshii | E. walshii | = E. wimmerensis | = E. wimmerensis |
| E. hawkeri | E. × silvestris | E. × silvestris | E. × silvestris |
| E. silvestris | E. × silvestris | E. × silvestris | E. × silvestris |
The morphological scheme largely accepts the current morphology-based species with minor adjustments on the basis of genetic findings, whereas the strict phylogenetic classification reduces the group to only those species with genetic evidence for representing distinct lineages. The final hybrid classification strikes a balance by synonymising species where there is evidence against them representing distinct lineages, but respects the morphological classification where there is a lack of evidence for distinctness.
