Phylogeny and classification of the coffee family (Rubiaceae, Gentianales): Overview and outlook

June 2024 | Sylvain G. Razafimandimbison & Catarina Rydin
The article provides an overview of the phylogeny and classification of the coffee family (Rubiaceae), a highly diverse angiosperm family with over 14,000 species. The authors, Sylvain G. Razafimandimbison and Catarina Rydin, present a consensus phylogeny and robust classification based on 130 studies, including recent phylogenomic works. They highlight the importance of molecular data in improving our understanding of the evolutionary history of Rubiaceae and its classification. The family is divided into two subfamilies: Dialypetalanthoideae and Rubioideae, with 71 tribes in total. The article discusses the monophyly of tribes and subfamilies, the geographic distributions of tribes, and the taxonomic and phylogenetic history of various genera. It also addresses the challenges in classifying certain tribes due to conflicting phylogenetic positions and the need for updated classifications. The authors provide a detailed classification scheme, including new tribal and generic limits, and discuss the implications for future ecological and evolutionary studies.The article provides an overview of the phylogeny and classification of the coffee family (Rubiaceae), a highly diverse angiosperm family with over 14,000 species.
