The Geraniales Phylogeny Poster (GPP) depicts the phylogenetic relationships between the five families of the order recognized here: Geraniaceae, Hypseocharitaceae, Vivianiaceae, Francoaceae, and Melianthaceae – down to the genus level – based on past and most recent research results. Unifying apomorphic, plesiomorphic, diagnostic, and nondiagnostic traits are mapped on the according nodes of the branches of the tree. All relevant morphological features are listed in a table to provide a clear overview and comparison between the genera. The purpose of the poster is to serve as a free, openly available educational tool and data resource for students, advanced scholars, researchers, and teachers.
This is one of a series of angiosperm phylogeny posters made available to the community for educational and reference purposes.
