Flora da Usina São José, Igarassu, Pernambuco: Zingiberales.

Zingiberales is represented in the Brazilian flora by almost 300 species, of which about 100 occur in the Northeast Region of the country. Zingiberales is poorly known in the Atlantic Forest of the state of Pernambuco and this study provides a taxonomic survey of the species found in the forest fragments of Usina São José, Igarassu. The field work was carried out in eight expeditions (from November 2013 to December 2014), as well as visits to herbaria: HST, IPA, PEUFR and UFP. In the studied area were found one species of Costaceae, three of Heliconiaceae and seven of Marantaceae. Heliconia episcopalis and Maranta subterranea are new records to the state. Identification key, descriptions, comments and illustrations are presented. [ABSTRACT FROM AUTHOR]
