Resumo

The Rutaceae are the largest family in number of species in the order Sapindales, with 162 genera and ca. 2085 species, mainly in (sub)tropical regions. The family is well distributed in the Americas, with 51 genera and 412-415 species, most of them in the tropical America, with 48 genera (46 endemic to this region), and 350-400 species. Forty-nine genera are restricted to America, only Thamnosma (also present in African) and (sub)tropical worldwide Zanthoxylum also occurring in other continents. Growing knowledge about the group, especially along the last 25 years, has led to a great internal rearrangement in the family systematics, mainly due to phylogenetic studies based on molecular data. In addition, studies of group reviews, descriptions of new species, and anatomical, cytogenetic, phytochemical, biogeographic and other studies have greatly expanded the knowledge about the evolution of the group. The present work provides a comprehensive overview of these studies in the Rutaceae, with an emphasis on taxa that occur in the American continent, notably in the Neotropical Region, and indicates groups that still need more in-depth studies, specially in a systematic point of view.
