Outcomes of Extensive Hybridization and Introgression in Epidendrum (Orchidaceae): Can We Rely on Species Boundaries?
Figure 2
Patterns of haplotype variation in three hybridizing species of Epidendrum (N = 304 plants).
A) Statistical parsimony network of plastid haplotypes based on sequences from four chloroplast regions (trnL-trnF, rps16, psbA- trnH and rpl16), a circle’s size being proportional to the haplotype frequency. Small empty circles represent single mutational steps. B) Geographic distribution of plastid haplotypes.
