ABSTRACT
Hibiscus sabdariffa is a pantropical species cultivated because of its economic importance. This species possibly originated in Sudan and was later taken to the rest of Africa, Southeast Asia, and Central America. Naturalization records of H. sabdariffa are known for the Neotropical region, although in Brazil it is only known as a cultivated species. We present here cases of naturalization of H. sabdariffa in the Brazilian flora, based on previous records and new collections made in the Amazon region. It is also included a description of the species, an identification key for the Hibiscus species from Amazon, a photographic plate and the geographic distribution of the species in the neotropics.
