Phylogram for Thesiaceae that includes Thesium nautimontanum sp. nov. (bold). Values at the nodes indicate maximum likelihood bootstrap, maximum parsimony bootstrap and Bayesian posterior probabilities. The scale bar represents number of substitutions per site. Branch lengths are proportional to the amount of substitutional change, except for the branch connecting the outgroup to the ingroup (here shorted for graphical purposes). Group (clade) names are from Nickrent and García (2015). The colour coding for the taxa indicates the general geographic distribution for the species as shown in the inset.
