Figure 2

Geographical distribution of O. secunda chloroplast trn S- trn G haplotypes. Pie chart sizes are approximately proportional to sample size, with the smallest circles representing N = 1 and the largest representing N = 8. Inset shows the phylogenetic relationships between the seven haplotypes. Small black circles represent unique haplotypes i.e. those found in a single individual. The population of origin of each unique haplotype is indicated.
