Resumo: The Pampa represents one of the domains of highest floristic richness in South America, however, especially in relation to the ferns and lycophytes, it still poorly known. This study aims to list the ferns and lycophytes associated with the Tigre and Palomas hills and discuss the floristic aspects that shape the fern and lycophyte flora at the isolated formations (Cerros) of the Pampa domain. The samples were collected and herborized using standard techniques and identified through specific literature. Herbarium specimens were also analyzed in order to complement the floristic list. Species were classified according to their geographical distribution pattern and also considering their life and growth forms. The inventory resulted in 36 species, representing four lycophytes and 32 ferns, distributed in 11 families and 19 genera. Overall, 18 species were exclusive to Cerro do Tigre, five to Cerro Palomas and 13 shared between both areas. Most of the species are widely distributed in South America (41,02%) and Tropical America (35,89%), and no endemic species to the pampean domain were identified. The predominant life form was hemicryptophyte, and rosulate was the most represented growth form. In general, the species occurring in the areas presented adaptations to xerophytic conditions. The results showed a high species richness in the studied areas in relation to cited for the whole domain, indicating that the Cerros serve as refuges for the maintenance of ferns and lycophytes in the Pampa region.

O presente estudo tem como objetivos listar as espécies de samambaias e licófitas associadas aos cerros do Tigre e Palomas e discutir os aspectos florísticos que modelam a flora de samambaias e licófitas nas formações isoladas (Cerros) do domínio do Pampa. As amostras foram coletadas e herborizadas por meio das técnicas usuais, e identificadas com auxílio de literatura específica. Espécimes de herbários também foram analisados a fim de complementar a lista florística. As espécies foram classificadas quanto seu padrão de distribuição geográfica e quanto sua forma de vida e crescimento. O inventário resultou em 36 espécies, sendo quatro licófitas e 32 samambaias, distribuídas em 11 famílias e 19 gêneros. Ao todo, 18 espécies foram exclusivas ao Cerro do Tigre, cinco ao Cerro Palomas e 13 ocorreram em ambas as áreas. A maior parte das espécies tem ampla distribuição na América do Sul (41,02%) e América Tropical (35,89%), e não foram identificadas espécies endêmicas ao domínio pampeano. A forma de vida predominante foi hemicriptófito e a forma de crescimento, o rosulado foi a mais frequente. De forma geral as espécies ocorrentes na área de estudo apresentaram adaptações às condições xerofíticas. Nossos resultados mostraram haver alta riqueza de espécies nas áreas estudadas em relação ao citado para o domínio, e que os Cerros servem como refúgios para manutenção da flora de samambaias e licófitas na região.SciELO PreprintsSciELO PreprintsSciELO Preprints2020-06-03info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/70010.1590/2236-8906-76/2019porhttps://preprints.scielo.org/index.php/scielo/article/view/700/922Copyright (c) 2020 Carlos Rodrigo Lehn, Felipe Gonzatti, Marcelo Daniel Aranahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLehn, Carlos Rodrigo Gonzatti, Felipe Arana, Marcelo Daniel reponame:SciELO Preprintsinstname:SciELOinstacron:SCI2020-06-03T02:42:39Zoai:ops.preprints.scielo.org:preprint/700Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2020-06-03T02:42:39SciELO Preprints - SciELOfalse
