Resolved phylogenetic relationships in the <i>Ocotea</i> complex ( <i>Supraocotea</i> ) facilitate phylogenetic classification and studies of character evolution

Premise The Ocotea complex contains the greatest diversity of Lauraceae in Neotropics. However, traditional taxonomy group has relied on only three main floral characters, and previous molecular analyses have used a few markers provided limited support for relationships among major clades. This lack useful data hindered development comprehensive classification, as well studies character evolution. Methods We RAD-seq to infer phylogenetic 149 species complex, generating reference-based assembly using Persea americana genome. results provide basis classification that reflects our current knowledge evolution breeding system, stamen number, number anther locules. Results recovered well-supported tree demonstrates paraphyly Licaria, Aniba, clarifies Umbellularia, Phyllostemonodaphne, Old World species. To begin new facilitate precise communication, we also definitions seven Our ancestral reconstructions show multiple origins characters routinely been systematics, suggesting these be with caution future. Conclusions study advances understanding taxonomically difficult data. names will unambiguous communication progress.
