FIGURE 1 in On the morphological, biological and genetic heterogeneity of the genus Orchis (Orchidaceae, Orchidinae)

FIGURE 1. Maximum clade credibility tree of ITS sequences of 26 Orchis species with Traunsteinera globosa as outgroup, inferred with Bayesian relaxed clock analysis. Original data were from Bateman et al. (2003). The uncorrelated lognormal clock model was used, and the root height was fixed at 1.0. Posterior distributions of parameters were approximated using two independent Markov chain Monte Carlo analyses of 2.0 × 107 generations followed by a discarded burn-in of 2.0 × 106 generations (10%).
