Summary of strongly supported Oxalis clades represented on the ITS phylogenetic tree from our study. Numbered clades correspond to those described by Oberlander et al. (2011) [19] and as mentioned in the text and figures throughout this article. Basal relationships amongst the Clade 4 lineages are unresolved in this ITS phylogenetic tree. The annotations of number of species refer to the number included in our study, which is approximately 50 % of all southern African Oxalis.
