Geographic and taxonomic distributions of haplotypes in Cyrtandra. psbA-trnH is a plastid locus and Cyrt2 and Cyrt4 are two nuclear loci. The left-hand side shows the haplotype network and the geographical distribution of alleles. Empty circles indicate “ghost” alleles (intermediate alleles that were not recovered in any of the accessions sampled). Thickened rectangles indicate species-diagnostic haplotypes. The right-hand side shows the taxonomic distribution of the haplotypes.
