      Abstract

      Resumo Os resultados aqui apresentados fazem parte de um trabalho maior que consiste na Flora Vascular da Pedra do Elefante, Nova Venécia, Espírito Santo. As expedições a campo foram realizadas de março de 2010 a julho de 2016, em um total de 23 visitas ao local. As amostras foram incorporadas principalmente nos herbários CEPEC, MBML, RB, UPCB, VIC e VIES. Sessenta e três espécies, uma subespécie, três variedades e dois híbridos de samambaias e licófitas foram registradas, distribuídas em 32 gêneros e 15 famílias. As famílias mais representativas foram Pteridaceae (14 spp.), Polypodiaceae (11 spp.), Anemiaceae (9 spp.) e Selaginellaceae (5 spp.). Os gêneros mais representativos foram Anemia (9 spp), Selaginella (5 spp.), Adiantum e Pteris (4 spp. cada). Dentre estas, três espécies são novas ocorrências para o Espírito Santo e oito táxons apresentam estado de conservação. Chaves de identificações em nível genérico e específico, comentários, e distribuição geográfica para todos os táxons são apresentados. Inventários florísticos no Espírito Santo são importantes, principalmente em áreas que possuem afloramentos rochosos, pois o baixo esforço de amostragem e a alta pressão antrópica, causam impactos negativos na preservação da vegetação nativa.

      Abstract The results presented here are part of a broader work dealing with the Vascular Plants of Pedra do Elefante, Nova Venécia, Espírito Santo. Fieldwork was carried out from March 2010 to July 2016, totaling 23 expeditions. Samples were mainly incorporated in CEPEC, MBML, RB, UPCB, VIC and VIES Herbaria. Sixty-three species, one subspecies, three varieties and two hybrids of ferns and lyophytes were recorded, which are distributed in 32 genera and 15 families. The most representative families were Pteridaceae (14 spp.), Polypodiaceae (11 spp.), Anemiaceae (9 spp.) and Selaginellaceae (5 spp.). The most representative genera were Anemia (9 spp), Sellaginella (5 spp.), Adiantum and Pteris with (4 spp) each. Among these, three species are new records for the state of Espírito Santo and eight taxa present coservation status. Identification keys at generic and specific level, comments, and geographic distribution for all taxa are also presented. Floristic inventories in Espírito Santo are important, mainly in areas that have rocky outcrops, because low sampling effort and high anthropic pressure, cause negative impacts on the preservation of native vegetation.

        Diversity of ferns and lycophytes in Brazil

        Abstract This compilation of ferns and lycophytes in Brazil is an update of the one published in 2010 in Catálogo de Plantas e Fungos do Brasil. The methodology consisted in collecting data from regional checklists, taxonomic revisions, and selected databases. Invited specialists improved the list accessing a website housed at the Jardim Botânico do Rio de Janeiro. The results show 1,253 species: 1,111 of ferns and 142 of lycophytes. This number is 6.5% higher than the previous one (1,176 spp.). The percentage of endemic species decreased from 38.2% to 36.7%. We recognized 36 families and 133 genera (vs. 33 families, 121 genera in 2010). The 10 most diverse families are Pteridaceae (196 spp.), Dryopteridaceae (179), Polypodiaceae (164), Hymenophyllaceae (90), Thelypteridaceae (86), Aspleniaceae (78), Lycopodiaceae (64), Selaginellaceae (55), Anemiaceae (51), and Cyatheaceae (45). The three most diverse genera are still Elaphoglossum (87 spp.), Thelypteris (85), and Asplenium (74). The richest phytogeographic domain continues to be in the Atlantic Rainforest with 883 species which also has the largest number of endemic and threatened species, followed by the Amazon Rainforest (503), Cerrado (269), Pantanal (30), Caatinga (26), and Pampa (eight). Minas Gerais remains as the richest state (657 spp. vs. 580 in 2010).
