Synopsis of Marantaceae in the state of Pernambuco, Brazil

Abstract

The territory of Pernambuco includes portions of the Caatinga and the Atlantic Forest, which house areas of extreme biological importance that are also rich in Marantaceae species. This study presents a synopsis of the Marantaceae from the state, and was based in the morphological analysis of herbaria specimens and other collected in field excursions carried out from 2013 to 2018. We found 26 species belonging to 10 genera; Maranta (seven spp.) and Goeppertia (five spp.) were the most representative. Ctenanthe casupoides Pertersen and Hylaeanthe hexantha are new records for the state and Goeppertia yoshida-arnsiae, G. widgrenii and Maranta gigantea are considered threated. Ten species are endemic to the Atlantic Forest, and four are restricted to Northeastern Brazil. Regarding the local distribution, we observed that 22 spp. (85%) occur in the lowland semideciduous seasonal forest. Identification keys, comments on geographic distribution and habitats, local distribution maps, and photo plates of the species are provided.
