A Phylogenetic Analysis of Salix (Salicaceae) Based on matK and Ribosomal DNA Sequence Data
Figure 4
(a) matK haplotype network superimposed on ITS-based phylogenetic outline, assuming vertical transmission of all cp haplotypes. (b) matK haplotype network superimposed on ITS-based phylogenetic outline, assuming lateral transmission (dashed lines) of cp haplotype due to introgression (see Figure 3 for explanation of symbols).
