Abstract

This paper presents the revision of Mitracarpus from Brazil. The study is based on field observations and study of herbarium specimens. Mitracarpus is a neotropical genus, distributed from the southern United States to central Argentina, with one invasive species occurring in the Old World. The genus presents three centres of diversity: Mexico, the Caribbean region and Brazil. Twenty four species are accepted, of which six are new to science: Mitracarpus albomarginatus, M. buiquensis, M. diversifolius, M. eitenii, M. nitidus and M. robustus. A key to identify the species, updating of the names and their typification, synonymy, descriptions, illustrations are provided, together with data on their conservation status.

Key words:
conservation; Neotropics; Rubioideae; taxonomy
