FIGURE 4. Ancestral character state reconstructions of selected morphological characters using Maximum Parsimony, on the 50 % majority rule tree resulting from a Bayesian analysis of morphological and molecular evidence for species of Hechtia and selected outgroup. A. Growth pattern. B. Foliar margin. C. Ovary position. See Appendix 2 for a list of morphological characters used in the analysis. For this, we used the consensus tree of 50 % majority of Bayesian inference using the total evidence, and the reconstruction of the ancestral states was done through parsimony.
