A new remarkable Vanilla Mill. (Orchidaceae) species endemic to the Espinhaço Range, Brazil: its phylogenetic position and evolutionary relationships among Neotropical congeners

Maximum Likelihood analysis of Vanilla (Orchidaceae) based on ITS (nrDNA). Bootstrap values (%) >50 obtained by maximum parsimony analysis (MP) are given below the branches, while posterior probabilities values > 0.5 (BI) are given above branches. Vertical colored bars refer to the geographic distribution of Vanilla. The black arrow indicates the position of V. rupicola among the Neotropical thick-leafed Vanilla. The colored branches in the cladogram refer to Neotropical Vanilla groups according to the infrageneric classification presented in Soto-Arenas and Cribb (2010). AM = Amazonas, GO = Goiás, PA = Pará.
