Rubiaceae Juss. at Camanducaia municipality, Minas Gerais

Rubiaceae is a cosmopolitan family, mainly distributed along tropical and subtropical regions throughout the world, and comprises around 620 genera and 13000 species. In Brazil 120 genera and 1392 species have been recognized. The Atlantic Rain Forest, considered to be a hotspot for biodiversity conservation, harbors ca. 600 Rubiaceae species. The Mantiqueira Mountain Range, in which Camanducaia municipality is located, Southern Minas Gerais, exhibits important remnants of this phytogeographic domain. This study aims to produce a taxonomic monograph about the Rubiaceae at Camanducaia municipality, as well as to produce an interactive key of multiple entries for the inventoried species, and to asses phytogeographic aspects of the region on the basis of native species geographic distribution analysis. The Rubiaceae family is represented at Camanducaia municipality by 17 genera and 34 species, two subspecies and two varieties. The most diverse genera were Psychotria, presenting seven species, followed by Manettia and Borreria, both presenting five species. A taxonomic monograph is presented. The geographic distribution analysis of the selected species corroborates for a separation of southern and northern Atlantic forests. Within this context, the Camanducaia region performs the function of corridor and refuge of species endemic to the southern Atlantic forest. An interactive key of multiple entries for the inventoried species is presented (AU)
