ResumoO presente estudo teve como objetivo caracterizar a flora fanerogâmica da região da Serra Negra localizada no sul da Zona da Mata de Minas Gerais, entre os municípios de Lima Duarte, Rio Preto, Santa Bárbara do Monte Verde e Olaria. Embora considerada de importância biológica alta, esta região não possui nenhum registro anterior de dados florísticos, o que levou ao desenvolvimento deste levantamento, durante o período de 2003 a 2010. A vegetação é caracterizada por um mosaico de formações florestais e campestres onde se destacam os campos rupestres e florestas nebulares em altitudes que variam de 1300 a ca. 1700 m. Um total de 1033 espécies foi encontrado, distribuídas em 469 gêneros e 121 famílias sendo as mais representativas Orchidaceae (115 spp.), Asteraceae 54 spp.), Melastomataceae (56 spp.), Myrtaceae (53 spp.), Fabaceae, Poaceae e Rubiaceae (48 spp. cada), Bromeliaceae (43 spp.), Solanaceae (38 spp.) e Piperaceae (33 spp). Novos registros e endemismos para a flora mineira foram encontrados e 58 espécies estão citadas na lista de espécies ameaçadas de Minas Gerais.

AbstractThe present study aims to characterize the phanerogamic flora of the region of Serra Negra, located in the southern of Zona da Mata of Minas Gerais, between the municipalities of Lima Duarte, Rio Preto, Santa Bárbara do Monte Verde and Olaria. Although this region is considered of high biological importance, it has no previous record of floristic data, which led to the development of this survey, during the period 2003 to 2010. The vegetation is characterized by a mosaic of forests and grassland, especially cloud forests and "campos rupestres" (rocky grasslands), occurring at altitudes between 1300 to 1700 m. A total of 1033 species was recorded, distributed in 469 genera and 121 families. The most representative families are Orchidaceae (115 spp.), Asteraceae 54 spp.), Melastomataceae (56 spp.), Myrtaceae (53 spp.), Fabaceae, Poaceae e Rubiaceae (48 spp. cada), Bromeliaceae (43 spp.), Solanaceae (38 spp.) and Piperaceae (33 spp). New records and endemic species to flora of Minas Gerais were found and 58 species are cited in the list of endangered species of Minas Gerais.

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.

Pteridófi tas da Serra Negra, Minas Gerais, Brasil RESUMO (Pteridófi tas da Serra Negra, Minas Gerais, Brasil). Este trabalho apresenta uma lista de espécies de pteridófi tas que ocorrem na Serra Negra, Minas Gerais. A serra está inserida no complexo da Serra da Mantiqueira situada entre Rio Preto, Lima Duarte, Santa Bárbara do Monte Verde e Olaria, tendo seus limites nos pontos 21º58'11"S 43º53'21" W, 22º01'46,4" S 43º52'31,5" W, 21º58'21,4" S 43º50'06,5" W e 21º58'53" S 43º56'08" W. A vegetação da serra é formada por um mosaico de fi tofi sionomias, sendo encontradas formações fl orestais (fl orestas ombrófi las e semidecíduas) e campestres (campos rupestres). O inventário fl orístico foi realizado entre os anos de 2003 e 2008, em excursões mensais para coleta de amostras e registro de dados. Na serra foram registradas 209 táxons infragenéricos distribuídas em 24 famílias e 75 gêneros. As famílias com maior número de espécies foram Polypodiaceae (40), Dryopteridaceae (33) e Pteridaceae (25). A maioria das espécies (109) foi encontrada ocorrendo exclusivamente no interior de fl oresta. Em relação ao hábito, 69 espécies foram encontradas exclusivamente como terrestres, 37 como rupícolas ou terrestres e 32 exclusivamente epífi tas. Este trabalho revela uma elevada riqueza de pteridófi tas na região e indica a importância de estudos desta natureza na conservação e manejo das pteridófi tas em Minas Gerais. Palavras ABSTRACT(Ferns and lycophytes of Serra Negra, Minas Gerais, Brazil). Th is work presents an inventory of pteridophyte species that occur in the Serra Negra, of Minas Gerais. Th e area is part of the Mantiqueira Range, and is situated between the coordinates 21º58'11"S 43º53'21" W, 22º01'4.4" S, 43º52'31.5" W, 21º58'21.4" S, 43º50'06.5" W and 21º58'53" S, 43º56'08" W. Th e vegetation in the Serra Negra is characterized by a mosaic of diff erent phytophysiognomies, divided into forests (evergreen and seasonal semideciduous forests) and open formations (rocky grasslands). Th e inventory was carried out from 2003 to 2008, during monthly excursions to collect botanical material and data in the study area. A total of 209 species, distributed in 24 families and 75 genera, were recorded. Th e families with the highest number of species were Polypodiaceae (40), Dryopteridaceae (33) and Pteridaceae (25). More than the half (110) of the inventoried species were recorded exclusively in the forests formations. Sixty-nine species were terrestrial, 37 were saxicolous or terrestrial and 32 were epiphytes. Th is work shows that this region is rich in ferns and reveals the importance of this kind of study for conservation and management of pteridophytes in the state of Minas Gerais.

A região da Serra Negra constitui um importante remanescente de floresta atlântica situado no sul da Zona da Mata mineira, na Serra da Mantiqueira, composta por um mosaico de campos rupestres (nos afloramentos de quartzito) a arbustais nebulares, florestas estacionais semideciduifólias a perenifólias e florestas nebulares, de ambientes inferomontanos a superomontanos ripícolas a interfluviais. A área de estudo é um fragmento de floresta de grota (floresta perenifólia ripícola), de aproximadamente 0,9 ha, situada no Cânion do Ribeirão do Funil, na Vila do Funil, município de Rio Preto, localizada no sul da Serra Negra. O presente trabalho foi realizado entre os anos de 2004 e 2009 e teve como objetivos o conhecimento da flora vascular não-arbórea, a discussão dos hábitos e habitats das plantas e a descrição da fisionomia do fragmento. Foram registrados 157 táxons de plantas vasculares (sendo 41 pteridófitas e 116 angiospermas), pertencentes a 48 famílias (10 de pteridófitas e 38 de angiospermas). As famílias de maior riqueza específica foram Orchidaceae, dentre as angiospermas, com 27 espécies e Pteridaceae, dentre as pteridófitas, apresentando 11 espécies. O hábito mais representativo foi o herbáceo (124 spp.), destacando-se as espécies epífitas (42 spp.), que perfazem cerca de 25% de todas as espécies registradas na área. Doze espécies estão incluídas na lista de espécies ameaçadas de extinção no estado de Minas Gerais (duas pteridófitas e 10 angiospermas). O elevado número de espécies encontradas em uma área consideravelmente pequena ressalta a importância deste fragmento para a diversidade da Serra Negra e aponta para a necessidade de implantação de um plano de ação para sua conservação.

Initiatives directed at managing information on aquatic plants can support different areas of scientific research, educational practices and political decisions for sustainable management and protection of wetlands and natural resources, as well as reveal knowledge gaps regarding aquatic plants and wetlands. Furthermore, such initiatives can contribute directly to consolidating wetland classification systems in Brazil. The objectives of this work are to present and explore the use of a data repository and online platform created specifically for the management of data on aquatic plants in Brazil. The data repository for aquatic plants was developed to store information on species occurrence records in a standardized form considering: systematics, taxonomy, habit, life form, geographic distribution, hydrographic basin, wetland, bibliographic references and herbarium material. A total of 3,903 records referring to the Southeast Region of Brazil were generated for the data repository. This total encompassed 1,036 species distributed among 132 families and 466 genera. Our results illustrate the diversity of information available regarding aquatic plants, circumscribe this group of species and serve as a source of data about them. Similar databases and electronic infrastructures can be developed for other flora in the future.
