Abstract

This study presents the first records for Maranhão state, northeastern Brazil, of the duckweeds Lemna valdiviana Phil., Wolffia brasiliensis Wedd. and Wolffiella lingulata (Hegelm.) Hegelm. The species were collected in a survey of water bodies in the muncipalities of Caxias, Igarapé do Meio and São João do Sóter. Descriptions, illustrations, maps, georeferenced specimen citations and an identification key are provided. These new records contribute to the expansion of the knowledge of the Maranhão flora and the geographic distribution of the Lemnoideae of the Northeast region of Brazil.
