Plastid haplotype diversity in <i>Dioscorea humilis</i>.

<p>A. Geographical distribution of eight chloroplast haplotypes in 17 populations of <i>Dioscorea humilis</i>. Pie charts indicate relative frequencies of each haplotype in each population. The dotted line indicates the location of the Maipo river. Chilean administrative regions and climatic regions are indicated as in Fig. 1. B. Parsimony Network showing the relationships among eight haplotypes. Black dots indicate unsampled or extinct haplotypes. The size of the circles or squares is proportional to the number of sequences representing each haplotype, and is indicated in parentheses when higher than one.
