FIGURE 2. Phylogenetic relationships and morphological differentiation of Stenanona zoque. A. From top to bottom, flowers of Stenanona migueliana, Stenanona stenopetala and Stenanona zoque. B. The Bayesian tree based analysis of seven plastid regions (psbA-trnH, trnL-F, rps16-trnQ introns/spacers and matK, ndhF, rbcL and ycf1 exons) and nuclear ribosomal ITS (modified from Ortiz-Rodriguez et al. 2018). In the phylogenetic tree Stenanona zoque (in red) is placed in subclade A of the Desmopsis-Stenanona clade.
