FIGURE 2 in Genetic structure of Ipomoea imperati (Convolvulaceae) in the Mediterranean region and implications for its conservation

FIGURE 2. Median-joining network for plastid DNA haplotypes in Mediterranean, Mexican and Honduran samples of Ipomoea imperati. Haplotypes are represented by the circles, the size of each being proportional to the observed frequency of each haplotype. Median vectors are labelled mv1 and mv2; these represent possible unsampled or extinct haplotypes. Information on the geographic locations where each haplotype is found is provided in Table 1.
