Resumo: | Mountaintops are often refugia for vegetation because they are generally isolated islands distinct from the surrounding vegetation, often harboring rare and endemic species. In recent years, many rare species that were once thought to be extinct or on the brink of extinction have been rediscovered in mountain regions. This is the case with the species presented here, which were rediscovered after decades, or were previously unknown to science. Ongoing floristic studies in peatlands areas in Chapada do Couto have revealed the existence of six rare species of Eriocaulaceae, endemic from the Espinhaço Meridional and associated with wet ecosystems. Two species belong to Actinocephalus genus and four belong to Paepalanthus genus, including one rediscovered and two species still unknown to science. Given the rarity of their occurrences, the high degree of endemism, and the fragility of the ecosystems of mountaintops, the conservation status of these species is presented, along with comments on their morphology, geographical distribution, and photos of each of the species. |

Nos últimos anos, muitas espécies raras que antes se pensava estarem extintas ou à beira da extinção foram redescobertas em regiões montanhosas. É o caso das espécies apresentadas aqui, que foram redescobertas depois de décadas, ou são ainda desconhecidas pela ciência. Os estudos florísticos em andamento em áreas de turfeiras no alto da Serra do Espinhaço Meridional, especificamente na Chapada do Couto, revelaram a existência de seis espécies raras de Eriocaulaceae, endêmicas dessas áreas elevadas do Espinhaço Meridional e associadas a ecossistemas úmidos. Duas espécies pertencem ao gênero Actinocephalus e quatro ao gênero Paepalanthus, incluindo uma redescoberta e duas espécies ainda desconhecidas pela ciência. Dada a raridade das ocorrências, o alto grau de endemismo e a fragilidade dos ecossistemas dos topos de montanha, são apresentados o estado de conservação destas espécies, além de comentários sobre morfologia, distribuição geográfica e imagens ilustrando cada uma delas.UFVJM2023-04-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/23910.5281/zenodo.7868219Revista Espinhaço ; Revista Espinhaço #212317-0611reponame:Revista Espinhaçoinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMporhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/239/223Copyright (c) 2023 Revista Espinhaço https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCosta, Fabiane Nepomuceno Andrino, Caroline Oliveira Negrão, Raquel 2023-04-26T18:28:24Zoai:ojs.pkp.sfu.ca:article/239Revistahttps://revistaespinhaco.com/index.php/revista/indexPUBhttps://revistas.ufvjm.edu.br/revista-espinhaco/oairevista.espinhaco@gmail.com || doug.sathler@gmail.com2317-06112317-0611opendoar:2023-04-26T18:28:24Revista Espinhaço - Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)false |
