Serra da Canastra National Park is located in southwestern Minas Gerais State and contains several phytophysiognomies of the Brazilian Cerrado. To date, no study on bryophytes has been conducted in this area and the present study is the fi rst to be carried out in this major biological reserve of Cerrado located on the Brazilian Plateau. Th is study found 289 species of bryophytes, including mosses, liverworts, and one species of hornwort, representing fourtyone Brazilian endemic species and 56 new records for Minas Gerais State. Most species are widely distributed in Brazil, with only 16% having restricted distributions. Regarding worldwide distribution, 31% are Neotropical. Lejeuneaceae had the highest species richness among liverwort families with 53 species, whereas Sphagnaceae had the highest richness among moss families with 26 species. Phaeoceros laevis was the only hornwort species found in the park. Th is study contributes to the understanding of bryophyte species richness and distribution, and provides the worldwide and Brazilian distribution of the bryophyte fl ora of Serra da Canastra National Park, an important center for biodiversity conservation.

The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora.
RESUMO Parque Estadual de Campos do Jordão é uma importante área remanescente da Mata Atlântica e não apresenta levantamentos brioflorísticos. O objetivo deste estudo foi realizar o levantamento da flora de briófitas do PECJParque e, desta forma, fornecer dados sobre a diversidade desse grupo vegetalina área, destacando aquelas espécies que representam novas ocorrências para o Estado de São Paulo. O estudo emgloba amostras coletadas desde o final da década de 1960 até o final de 2017. Como resultado, este estudo apresenta 490 espécies, das quais dessas 63 são endêmicas do Brasil e 26 são novas ocorrências para o Estado de São Paulo. As famílias de musgos mais diversas na área são Orthotrichaceae (22 spp.), Bryaceae (21 spp.), Pottiaceae (21 spp.) e Fissidentaceae (20 spp.). Com relação às hepáticas, Lejeuneaceae (80 spp.) é a maior família encontrada no PECJ.
RESUMO A Reserva Particular do Patrimônio Natural (RPPN) da Serra do Caraça está localizada no complexo orográfico da Cadeia do Espinhaço e caracteriza-se como uma área de transição entre dois importantes domínios fitogeográficos brasileiros, a Mata Atlântica e o Cerrado. Essa Reserva é composta por diferentes tipos de formações vegetais e apresenta, predominantemente, os campos rupestres. Na Reserva Particular do Patrimônio Natural da Serra do Caraça foram encontradas 439 espécies de briófitas (238 musgos, 199 hepáticas e dois antóceros), 74 (17%) espécies endêmicas brasileiras e 80 (18%) novos registros para o Estado de Minas Gerais. A família de hepáticas Lejeuneaceae foi a mais rica, com 75 espécies, enquanto Sphagnaceae apresentou maior riqueza para os musgos, com 29 espécies. A maioria das espécies encontradas apresenta uma distribuição moderada para o país e são neotropicais.
