Fig. 4. Phylogenetic tree derived from the partial ITS sequences (506 positions) of the 125 accessions listed in Table 1, showing the differentiation of the Vanilla sotoarenasii M.Pignal, Azofeifa-Bolaños & Grisoni sp. nov. clade from V. planifolia Jacks. ex Andrews and all other related species. The tree was inferred using the Maximum Likelihood method based on the Tamura-Nei model with invariant sites and Gamma distribution of evolutionary rates. The Fgures indicate the percentage of bootstrap support. Branches with less than 65% support were collapsed. Countries of origin: Bra = Brazil; Com = Comoros: CR = Costa Rica; FGu = French Guiana; FPo = French Polynesia; Gua = Guatemala; Hon = Honduras; Mad = Madagascar; May = Mayotte; Mex = Mexico; Run = La Réunion; na = geographic origin not available. Numbers in brackets indicate the number of similar accessions merged in one branch for outgroup species.
