Overview map including all analysed samples. Geographic distribution of nuclear-inferred (a) and plastid-inferred (b) lineages within sampled Ixora. Phylogenetic relationships of distinguished nuclear and plastid lineages are depicted as schematic cladograms, root as defined by outgroups (branches with non-high support collapsed to polytomies). Members of major lineages (see Fig. 1) coloured accordingly, grey: not genotyped individuals. Circles, non-Philippine individuals; 7-pointed stars, Palawan samples; 5-pointed stars, other Philippine samples
