This study provides an overview of the species richness of angiosperms in the Cerrado biome, based on data compiled from the Flora e Funga do Brasil platform. The objective was to analyze species diversity, with an emphasis on the richness of botanical families, culminating in the development of a list of the twenty most representative families in terms of the number of species recognized in the biome. A total of 186 botanical families were recorded, comprising 12,159 native species. Among these, 8,491 species (69.8% of the total) are concentrated in the twenty most representative families, highlighting a non-homogeneous distribution of diversity. Variations in the number of recorded species between 2015 and 2025 in Fabaceae, Asteraceae, Orchidaceae, Melastomataceae, and Euphorbiaceae can be partly attributed to taxonomic revisions and reclassifications carried out during this period. The phylogenetic distribution reveals a balanced contribution of Rosids, Asterids, and Monocots, while the high levels of endemism in families such as Velloziaceae, Lythraceae, and Eriocaulaceae indicate specific patterns of association with the biome. The results underscore the importance of the Cerrado in shaping the diversity of angiosperms in Brazil, providing a foundation for future research and the development of effective management and conservation strategies for the biome.
