Flora of Anacardiaceae in the Upper Paraná Atlantic Forest

Abstract

Abstract The Atlantic Forest has one of the richest floras in the world and floristic surveys are essential to understand its biodiversity and promote its conservation. This study aims to contribute to the floristic understanding of Anacardiaceae in the Iguaçu National Park (Brazil) and the Iguazú National Park (Argentina). Monthly samplings were performed from 03/2019 to 02/2020 and sporadic samplings from 11/2020 to 01/2021 in the main trails from both parks, as well as herbarium review and surveys on virtual platforms. Two native species: Lithraea molleoides and Schinus terebinthifolia, and two exotic cultivated species: Mangifera indica and Spondias purpurea were found in the Iguaçu National Park and only one native species, Schinus terebinthifolia, in the Iguazú National Park. Identification key, descriptions, photographs with diagnostic characters of the taxa, taxonomic comments, geographical distribution, phenology, common names, uses and observations are provided.
