Item Acesso aberto (Open Access) Dryopteridaceae e Lomariopsidaceae (Polypodiopsida) do Campo Experimental da Embrapa Amazônia Oriental, Moju, Pará, Brasil(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2010-09) ROSÁRIO, Sebastião Maciel do; SILVA, Marcio Roberto Pietrobom daThis study presents the species of the families Dryopteridaceae and Lomariopsidaceae recorded at Embrapa's Eastern Amazonia Field Station. Dryopteridaceae is represented in the area by Cyclodium heterodon (Schrad.) T. Moore var. abbreviatum (C. Presl) A.R. Sm., C. inerme (Fée) A.R. Sm., C. meniscioides (Willd.) C. Presl var. meniscioides, Elaphoglossum discolor (Kuhn) C. Chr., E. flaccidum (Fée) T. Moore, E. laminarioides (Bory ex Fée) T. Moore, E. luridum (Fée) H. Christ, E. obovatum Mickel and E. styriacum Mickel. Lomariopsidaceae is represented by Lomariopsis prieuriana Fée, Nephrolepis biserrata (Sw.) Schott, N. brownii (Desv.) Hovenkamp & Miyam. and N. rivularis (Vahl) Mett. ex Krug. Identification keys for genera and species, descriptions, illustrations, geographical distributions and habitat data are presented.Item Acesso aberto (Open Access) Licófitas (Lycopodiophyta) do corredor de biodiversidade do norte do Pará, Brasil(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2015-03) GÓES NETO, Luiz Armando de Araújo; ROSÁRIO, Sebastião Maciel do; SILVA, Marcio Roberto Pietrobom da; VALDESPINO, Iván AlbertoA treatment of the lycophytes of the Northern Pará Biodiversity Corridor within the Guiana Endemism Center is presented. This article is part of the project “Diagnóstico da Biodiversidade das Unidades de Conservação estaduais do Mosaico Calha Norte, Estado do Pará”. The treatment includes keys as well as species descriptions. In the study area 14 species distributed in four genera (Palhinhaea, Phlegmariurus, Pseudolycopodiella and Selaginella) were registered. The most diverse genus was Selaginella with 10 species, of which S. fragilis A. Braun and S. revoluta Baker are new records for Pará, and S. gynostachya Valdespino and S. sandwithii Alston are reported here as new to the Brazilian flora.Item Acesso aberto (Open Access) Samambaias e licófitas do Parque Ecológico do Gunma, município de Santa Bárbara do Pará, estado do Pará, Brasil(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2010-06) COSTA, Jeferson Miranda; SILVA, Marcio Roberto Pietrobom daThe Gunma Ecological Park - PEG (Santa Bárbara do Pará, Pará state, Brazil) is one of the few preserved forest remnants in the metropolitan region of Belém. The PEG has a rich phanerogamic flora with rare species, but nothing is known about its seedless vascular-plant flora. Our aim is to present a floristic survey of ferns and lycophytes from Gunma Ecological Park. The 56 recorded species belong to 28 genera and 15 families. This is the first record for Lellingeria suspensa (L.) A.R. Sm. & R.C. Moran in Pará state and also for Polyphlebium diaphanum (Kunth) Ebihara & Dubuisson in the Brazilian Amazon. The richest families were Hymenophyllaceae (15 spp.), Dryopteridaceae (8 spp.), Polypodiaceae (7 spp.) and Pteridaceae (6 spp.). The genera with highest number of species were Trichomanes (7 spp.) and Elaphoglossum (6 spp.). The majority of the species were herbaceous (52 spp.), with epiphytic (30 spp.) and terrestrial (23 spp.) habitat, occurred exclusively in the understory (35 spp.) and presented American distribution (34 spp.). This result demonstrates the importance of Gunma Ecological Park for local/regional seedless vascular-plant flora preservation.
