Abstract:—The Serra dos Órgãos National Park (PARNASO) constitutes one of the largest remnants of the Brazilian rainforest in Rio de Janeiro state. In this biome, Bromeliaceae has one of its main centers of diversity, with 31 genera and 803 species, being more than 500 belonging to the subfamily Bromelioideae. The imprecision in the generic limits within Bromelioideae is evident, especially in those groups related to Aechmea, such as Billbergia, Hohenbergia and Quesnelia. As a part of the project Bromeliaceae Organensis in development in the Department of Botany of the Museu Nacional- UFRJ, the present work aims to inventory the species of Aechmea, Billbergia, Hohenbergia and Quesnelia on PARNASO, providing their morphological description and an identification key, in addition to data about their distribution, in general and inside the park. The taxonomic study was conducted through the analysis of dried specimens, collections and field observations. Six species of Aechmea, six of Billbergia, one of Hohenbergia and four of Quesnelia, were revealed. Although well represented in number of species, Billbergia is represented by a small number of herbarium records, with four species referenced by one or a few more samples in the collections. The locality is also home to populations of endemic species of Rio de Janeiro state, like A. wellbachii, A. fasciata, Q. lateralis and Q.edmundoi var. edmundoi.

Keywords:—Billbergia; Hohenbergia; Quesnelia.
