ABSTRACT This study documents the occurrence of threatened plant species on Ilha Grande, Rio de Janeiro State, Brazil. This survey acquired data from herbaria, living collections and field sampling. A total of 49 threatened species distributed among 27 families and 38 genera were recorded in the scientific collections, of which 43 are cited on official lists of threatened plant species for the State of Rio de Janeiro and Brazil. Twelve species recorded on the island are on an international list of endangered species, 30 on the national list for Brazil, and 11 on the State List of Rio de Janeiro. The IUCN Red List categories of Vulnerable and Endangered were the predominant categories for the plant species of Ilha Grande, with the main historical threat factors being deforestation and logging. Most of the threatened species of the island are arboreous. The families with the greatest number of threatened species are also among the richest in Dense Ombrophilous Forest: Melastomataceae, Myrtaceae, Meliaceae, Bromeliaceae and Orchidaceae.
