Data from: Phylogenetic relationships of genera Cladocolea and Struthanthus (Loranthaceae) with emphasis on the Mexican species
<p><em>Cladocolea</em> (Loranthaceae) is a neotropical genus currently containing 24 species. Its taxonomic history included changes in its circumscription as the transfers of some of its species to other genera of the family. Several phylogenetic studies of Loranthaceae have recognized a close relationship between <em>Cladocolea</em> and <em>Struthanthus</em>. However, both genera were poorly represented in these studies, so here we generate a phylogeny of Mexican species of <em>Cladocolea</em>, <em>Struthanthus</em>, and other genera of Psittacanthinae, using nuclear DNA sequences of the ITS region, as well as the chloroplast regions <em>matK</em> and <em>trnL-F</em>. One hundred twelve individuals were sampled and 12 GenBank sequences were included. We included 23 taxa of <em>Cladocolea</em> and 30 species of nine other genera of Loranthaceae. In order to estimate ancestral states and character evolution, 13 morphological characters were mapped, both vegetative and reproductive. Bayesian Inference and Maximum Likelihood analyses were performed using independent matrices and a concatenated matrix of 2842 characters. Our results show that <em>Cladocolea</em> and <em>Struthanthus</em> are both polyphyletic genera. However, the Mexican species of <em>Cladocolea</em> and <em>Struthanthus</em> with convolute or sigmoid styles form a monophyletic group. Finally, the analysis of ancestral character states indicates a trend towards a reduction of inflorescences in the <em>Cladocolea</em>-<em>Struthanthus</em> complex. New combinations and synonymies are proposed.</p>
