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.

There have been ethnoveterinary reports from around the world investigating plant usage in therapeutic protocols; however, there is no information regarding the ethnoveterinary practices in Brazilian Amazonia. The objective of this work was to register and document the ethnoveterinary knowledge of the inhabitants of the Island of Marajó, eastern Amazonia, Brazil. In the study, interviews were conducted with 50 individuals, with the application of semi-structured questionnaires that were quantitatively analyzed using descriptive statistic methods of frequency distribution. Use-value was calculated to determine the most important species. Samples of plants that were reported to have medicinal value were collected and identified by botanical classification. Fifty plants, distributed among 48 genera and 34 families, were indicated for 21 different medicinal uses. The family Asteraceae had the largest number of reported species; Carapa guianensis Aubl., Copaifera martii Hayne, Crescentia cujete L., Caesalpinia ferrea Mart., Chenopodium ambrosioides L., Jatropha curcas L. and Momordica charantia L. were species with highest use- value. The plant parts that were more commonly utilized for the preparation of ethnoveterinary medicines were the leaves (56%), bark (18%), roots (14%), seeds (14%) and fruit (8%). With regard to usage, tea was reported as a usage method by 56% of the informants; most preparations (90.9%) utilized only a single plant. In addition to medicinal plants, informants reported using products of animal and mineral origin. The present study contributed to the construction of an inventory of Marajó Island's ethnoveterinary plants, which might be the basis for future scientific validation studies.

Licófitas e samambaias da Serra do Itauajuri, município de Monte Alegre, Pará, Brasil
(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2016-12) GÓES, Julieta Pallos Pinto de Araújo; GÓES NETO, Luiz Armando de Araújo; COSTA, Jeferson Miranda; SOUZA, Filipe Soares de; SILVA, Marcio Roberto Pietrobom da
In this study we present the lycophytes and ferns inventoried in the Serra do Itauajuri, Pará state. Sixty four species distributed in 36 genera and 21 families were registered, with one family, one genus, and four species belonging to the lycophytes lineage, and 20 families, 35 genera, and 60 species belonging to the ferns lineage. The most representative families were Pteridaceae (19 spp.), Polypodiaceae (8), and Selaginellaceae (4). The genera with highest species richness were Adiantum (9 spp.) and Selaginella (4). Most species were collected as terrestrial (35 spp., ca. 55%), occurring in riparian forests (51 spp., ca. 80%), with American distribution pattern (46 spp., ca. 72%). We present two new records for the Northern Region of Brazil (Asplenium pumilum and Marsilea ancylopoda) and two for Pará state (Ophioglossum nudicaule and Selaginella minima). The studied area has distinct environmental characteristics than those commonly observed in Brazilian Amazonia, being a biologically important area. This results gathered information that can support the creation and implementation of the Serra do Itauajuri Conservation Unit, which will guarantee the preservation of its historic and natural wealth.
