Seventeen morphologically related genera have been considered as the Rondeletia complex, traditionally in Rondeletieae. Molecular studies agree that this is a polyphyletic group and some genera have been transferred to Guettardeae. Nevertheless, no s

The circumscription of Rondeletieae has changed considerably over time. Historically, 85 genera have been included, characterized by small trees, imbricate corolla aestivation and capsules. Molecular studies led to a narrower circumscription and stre

The conceptualization and coding of characters is a difficult issue in phylogenetic systematics, no matter which inference method is used when reconstructing phylogenetic trees or if the characters are just mapped onto a specific tree. Complex charac
