“…Spring (Alston et al 1981). Furthermore, Selaginella gynostachya Valdespino and Selaginella sandwithii Alston, reported from Brazil by Góes-Neto et al (2015) should be added to Hirai’s account as well. Accordingly, there are 58 well-documented native Brazilian Selaginella species and if we were to take into account the introduced taxa listed by Hirai (2015), i.e., Selaginella kraussiana (Kunze) A. Braun [native of Africa and Macaronesia (Alston et al 1981)], Selaginella plana (Desv.…”

We describe seven new species of Selaginella subg. Stachygynandrum (Selaginella alstonii, Selaginella blepharodella, Selaginella crinita, Selaginella mucronata, Selaginella mucugensis, Selaginella saltuicola, and Selaginella sematophylla) from Brazil and discuss their possible affinities and conservation status. Scanning electron micrographs of stem sections, leaves, and spores are provided to illustrate the new taxa. In Selaginella alstonii and Selaginella saltuicola vegetative growth from strobilus tips is reported and discussed. Four of the new species are from the Espinhaço Mountain Range associated with Campos Rupestres (montane savannah/rocky fields) vegetation. Three of these (i.e., Selaginella blepharodella, Selaginella crinita, and Selaginella mucugensis) were collected in the northern part of the range in Chapada Diamantina, state of Bahia, while Selaginella alstonii is from the southern part of the range in the state of Minas Gerais. Selaginella mucronata is found in Atlantic Rainforest vegetation in the state of Espírito Santo, whereas Selaginella saltuicola inhabits Cerrado (tropical savannah) vegetation in the state of Mato Grosso. Selaginella sematophylla is the most widely distributed of the new species and was collected in Espírito Santo, Minas Gerais, and Rio de Janeiro states in Campos Rupestres and Atlantic Rainforest vegetation. Selaginella alstonii occurs in rocky caves, Selaginella blepharodella, Selaginella crinita, Selaginella mucugensis, and Selaginella sematophylla seem adapted to seasonally dry places, living on sandy or humid soils, Selaginella mucronata occupies humid, forest understory, and Selaginella saltuicola is adapted to wet places associated with rocks or logs in waterfalls. Of the seven new species, six are considered local endemics (except for Selaginella sematophylla) because of their restricted currently known distributions to one or two localities within a single state in Brazil. Additionally, we propose new synonymy for Selaginella palmiformis (syn. = Selaginella bahiensis subsp. manausensis, ≡ Selaginella manausensis) and Selaginella vestiens (syn. = Selaginella fragillima); the last species is endemic to Brazil, recorded in the states of Goiás and Minas Gerais. Finally, based on literature discussed and this study, we conclude that the number of well-documented Brazilian Selaginella species is 61, of which 58 are native and three introduced and naturalized. These statistics are likely to change with further work on Selaginella from Brazil.

“…Como em estudos anteriores (i.e., Costa et al 2006a-b;Costa & Pietrobom 2007;Maciel et al 2007;Costa & Pietrobom 2010;Fernandes et al 2012;Góes-Neto & Pietrobom 2012;Góes-Neto et al 2015), onde são apresentados novos registros para o estado do Pará, para a Região Norte do Brasil (Amazônia brasileira) e até mesmo para o Brasil, no presente estudo também são citados dois novos registros para a Região Norte do país (Asplenium pumilum Sw. e Marsilea ancylopoda A. Braun) e dois para o Pará (Ophioglossum nudicaule L. e Selaginella minima Spring). Estes resultados em particular reafirmam a importância dos estudos florísticos para o conhecimento da flora de uma região, especialmente na Amazônia brasileira onde há inúmeras lacunas de coleta.…”

“…Com uma área de 1.248.000 km 2 , o estado do Pará destaca-se pelas cerca de 350 espécies de licófitas e samambaias registradas em seu território (Silva & Rosário 2008;Góes-Neto & Pietrobom 2012;Góes-Neto et al 2015). No entanto, apesar dos avanços obtidos no conhecimento da composição florística destes grupos vegetais no estado (Costa & Pietrobom 2010), o Pará ainda possui diversas áreas pouco ou nada amostradas, o que representa uma lacuna nas informações sobre a pteridoflora local, dificultando o entendimento da biogeografia e ecologia destes vegetais (Góes-Neto & Pietrobom 2012).…”

ResumoNeste estudo são apresentadas as licófitas e samambaias inventariadas na Serra do Itauajuri, estado do Pará. Foram registradas 64 espécies distribuídas em 36 gêneros e 21 famílias, sendo uma família, um gênero e quatro espécies pertencentes à linhagem das licófitas e 20 famílias, 35 gêneros e 60 espécies à linhagem das samambaias. As famílias mais representativas foram Pteridaceae (19 spp.), Polypodiaceae (8) e Selaginellaceae (4). Os gêneros com maior riqueza específica foram Adiantum (9 spp.) e Selaginella (4). A maioria das espécies foi coletada como terrestre (35 spp., ca. 55%), ocorrendo em matas ripárias (51 spp., ca. 80%), com padrão de distribuição americana (46 spp., ca. 72%). São apresentados dois novos registros para a Região Norte do Brasil (Asplenium pumilum e Marsilea ancylopoda) e dois para o estado do Pará (Ophioglossum nudicaule e Selaginella minima). A área estudada possui características ambientais bastante distintas do que comumente se observa na Amazônia brasileira, sendo uma área biologicamente importante. Os resultados obtidos neste trabalho reúnem informações que podem subsidiar a criação e a implementação da Unidade de Conservação da Serra do Itauajuri, o que garantirá a preservação de suas riquezas históricas e naturais. Palavras-chave: Amazônia brasileira, florística, formações campestres, mata ripária, pteridófitas. AbstractIn 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.

This is the first voucher-based record of Selaginella conduplicata Spring in the Brazilian Atlantic Forest and the Brazilian Northeast. This species was considered restricted to the Amazon Basin, and here we report its occurrence beyond the Amazonian limits, expanding its distribution. Illustrations of the diagnostic characters of the species, information of geographic distribution and conservation status are presented. Besides, we present description as well as taxonomic and nomenclatural comments.
