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
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.
