Synoptic checklist of Trioleneae (Melastomataceae), including 15 new lectotypes and an expert-validated taxonomic dataset

Here we summarize knowledge of the 45 accepted species and subspecies in the tribe Trioleneae (Melastomataceae). Fifteen lectotypes are designated, all available holotype and isotype locations are provided, and accepted synonyms for each species are listed. Country and district level distributions are curated, and distribution and species richness maps are provided. Validated notes on elevation, habit, habitat, and plant uses are also included. In addition, preliminary conservation assessments are completed according to IUCN criteria. Finally, representative specimens are cited and taxonomic issues discussed; possible synonyms are suggested for several taxa of uncertain delimitation and species complexes are highlighted that would benefit from further systematic research.
