Abstract
This study aimed to conduct a floristic survey on the family in the municipality of Camanducaia, Serra da Mantiqueira, southern Minas Gerais, where extensive remnants of Atlantic forest are found, and to produce an Interactive Key of Multiple Entries (IKME) for the identification of the species. The floristic survey was based on field expeditions and the analisys of the following herbaria: BHCB, ESA, HRCB, IAC, ICN, MBM, SP and UEC. Rubiaceae is represented in Camanducaia by 35 species, two subspecies and two varieties, classified in 17 genera. Borreria, Manettia and Psychotria were the most diverse genera (five species each). Nine species, one subspecies and one variety are endemic to the Atlantic forest. Two species (Galianthe vaginata e Psychotria beyrichiana) are endemic to the Serra da Mantiqueira and Serra do Mar. Psychotria beyrichiana is recorded for the first time in Minas Gerais. The utilization of the IKME here proposed made possible the identification of most of the taxa by utilizing only vegetative characters.
