Fig 4.
Median-joining networks of nrITS, four nuclear genes (Dbr1, SOS4a, SOS4b and PCRF1), and one chloroplast intergenic spacer (trnV-trnM) of Phyllagathis longicalcarata (in blue), Sporoxeia petelotii (in red) and the putative hybrid (in yellow).
The numbers on the connecting lines of haplotypes represents the number of mutational steps between them, while those without numbers represent one mutational step. The size of pie-charts is proportional to the frequency for each haplotype.
