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.

Uma retrospectiva do conhecimento taxonômico atual de Melastomataceae no Brasil é apresentada, constando uma abordagem histórica dos estudos já desenvolvidos e o cenário atual das circunscrições da família, tribos e gêneros. Também é abordada a distribuição geográfica do grupo nos diferentes domínios fitogeográficos, bem como o uso de novas ferramentas metodológicas, como filogenia e marcadores moleculares, para subsidiar propostas de novas classificações da família. São destacadas perspectivas de futuros estudos que possam contribuir para atualizar e preencher lacunas no conhecimento da diversidade do grupo na flora brasileira e apresentada uma chave de identificação para os gêneros no Brasil.

RESUMO Apresenta-se um estudo florístico para as Melastomataceae na Reserva Biológica de Poço das Antas, com enfoque na diversidade taxonômica e esta nas diferentes unidades vegetacionais que compõem a paisagem. Foram encontradas 34 espécies e uma variedade pertencentes a oito gêneros: Aciotis (1 sp.), Clidemia (5 spp.), Henriettea (1 sp.), Leandra (2 spp.), Miconia (15 spp. e 1 var.), Ossaea (2 spp.), Rhynchanthera (1 sp.) e Tibouchina (7 spp.). Esse trabalho representa o primeiro registro de ocorrência de 15 das espécies para a Reserva e para o município de Silva Jardim e o registro inédito de Clidemia dentata para o estado do Rio de Janeiro, além de identificar uma nova espécie de Clidemia. Apresenta-se uma chave analítica para a identificação das espécies, bem como descrições, ilustrações, dados de distribuição geográfica e comentários sobre particularidades morfológicas e nomenclaturais.

Apresenta-se um estudo sobre a diversidade taxonômica das Melastomataceae na Reserva Ecológica de Macaé de Cima, com enfoque nos táxons das tribos Bertolonieae, Merianieae e Microlicieae. Foram abordados 11 espécies e uma variedade pertencentes a seis gêneros: Behuria (2 spp.), Bertolonia (1 sp. e 1 var.), Bisglaziovia (1 sp.), Huberia (4 spp.), Meriania (2 spp.) e Trembleya (1 sp.). Apresentam-se chaves para a identificação dos 13 gêneros ocorrentes na Reserva e dos táxons pertencentes aos gêneros estudados, além de descrições, ilustrações, dados de distribuição geográfica e comentários sobre particularidades morfológicas. Behuria glazioviana, Huberia parvifolia e H. triplinervis são endêmicas de Macaé de Cima e, juntamente com Bertolonia grazielae, Behuria corymbosa, Bisglaziovia behurioides e H. minor, são endêmicas do estado fluminense. Meriania claussenii e Trembleya parviflora representam novas ocorrências para a Reserva.

The subtribe Ditaxinae in the plant family Euphorbiaceae is composed of five genera (Argythamnia, Caperonia, Chiropetalum, Ditaxis and Philyra) and approximately 120 species of perennial herbs (rarely annual) to treelets. The subtribe is distributed throughout the Americas, with the exception of Caperonia, which also occurs in tropical Africa and Madagascar. Under the current classification, Ditaxinae includes genera with a questionable morphology-based taxonomy, especially Argythamnia, Chiropetalum and Ditaxis. Moreover, phylogenetic relationships among genera are largely unexplored, with previous works sampling <10% of taxa, showing Ditaxinae as paraphyletic. In this study, we inferred the phylogenetic relationships within Ditaxinae and related taxa using a dataset of nuclear (ETS, ITS) and plastid (petD, trnLF, trnTL) DNA sequences and a wide taxon sampling (60%). We confirmed the paraphyly of Ditaxinae and Ditaxis, both with high support. Following our phylogenetic results, we combined Ditaxis in Argythamnia and upgraded Ditaxinae to the tribe level (Ditaxeae). We also established and described the tribe Caperonieae based on Caperonia, and transferred Philyra to the tribe Adelieae, along with Adelia, Garciadelia, Lasiocroton and Leucocroton. Finally, we discuss the main morphological synapomorphies for the genera and tribes and provide a taxonomic treatment, including all species recognized under each genus.
