    Abstract: 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.

    Abstract: There is little consensus on which environmental variables are best at predicting multiple dimensions of diversity. We ask whether there are common environmental correlates of diversity, despite ecological differences, across nine clades of plants and animals distributed along a single rainforest domain. For that, we compare the environmental correlates of species richness, phylogenetic diversity, and phylogenetic endemism. Location Brazilian Atlantic Forest. Taxon: Five clades of plants (Bromelioideae, Miconieae, Bertolonia , Cambessedesieae, and the Fridericia  and allies) and four clades of animals (butterlies in the tribe Ithomiini, frogs in the genera  Boana and  Proceratophrys , and birds in the subfamily Thraupinae). Methods Using curated occurrence localities and phylogenetic data, we generated maps of (a) species richness, (b) phylogenetic diversity, (c) residuals of phylogenetic diversity regressed on species richness, and (d) phylogenetic endemism for all groups. We also compiled a set of 30 environmental descriptors, including records of current temperature and precipitation, climatic stability over time, and topography. Through a machine learning framework, we explored the environmental correlates of each of these diversity measures for each group. Results The environmental variables used here were strong predictors of diversity for all studied groups. However, models for phylogenetic endemism had lower predictive power. Although patterns of diversity are different among groups, correlates of diversity are consistent across taxa. For both species richness and phylogenetic diversity, current precipitation and precipitation stability over time were consistently ranked among the variables that strongly correlate with diversity patterns. The correlates of phylogenetic endemism were less homogeneous across groups. The results suggest that including climate stability over time is important when predicting diversity measures that reflect historical components. Main conclusions Investigating environmental correlates of diversity for multiple clades and diversity measures in a single geographic area allows for a better understanding of common patterns across taxa. This study shows that environmental conditions, particularly precipitation, are good predictors of the patterns of species richness and phylogenetic diversity‐but not phylogenetic endemism‐across different Atlantic Forest groups.

    Abstract: The widespread Neotropical genus Melocactus of approximately 42 currently recognized species, is most diverse in eastern Brazil and the Greater Antilles, especially Cuba. Species delimitation is notoriously problematic in the group, although this is due in part to a lack of detailed systematic studies, as well as a severely cluttered nomenclatural history. To date, no comprehensive phylogenetic hypotheses have been generated for the clade, although some population genetic and morphological studies exist. We generated the largest phylogenetic dataset of Melocactus to date based on plastome data derived from a genome‐skimming approach for 26 taxa, which provided a framework for understanding species limits and relationships among Caribbean species. Our time‐calibrated phylogeny revealed a mid‐Pleistocene origin for Melocactus , and we resolved three major clades, a Cuban clade, a mostly South American clade, and a widespread Caribbean clade, which also included some South American taxa. Our topology recovered the Cuban clade as sister to the rest of the species, although this placement was poorly supported, and several other Cuban species are scattered throughout the rest of the tree. Biogeographic analyses suggested multiple dispersal events from South America leading to the current diversity on Cuba, as well as other parts of the Antilles. Based on our phylogenetic results, previous hypotheses of species numbers and relationships in the Caribbean generated solely on morphology have, in some cases, been greatly underestimated. Our study shows that plastome data are effective for resolving clades and species limits in Melocactus , although future work will need to include broader sampling and larger datasets to fully resolve relationships in this complicated group of cacti. We describe one new cryptic species for Cuba, Melocactus santiagoensis sp. nov., and provide a new combination ( Melocactus lagunaensis comb. & stat. nov.), based on our phylogenetic results and morphological data and typify numerous names in the genus. The genus Melocactus is another striking example of the exceptional diversity that has been generated in the poorly studied, seasonally dry tropical forest of the Greater Antilles.

    Abstract: The distribution of major clades in Bertolonia (Melastomataceae) is congruent with subareas of the Atlantic Forest, providing an opportunity to estimate ages of historical breaks in the Atlantic Forest, from its major north/south split to more restricted local radiations. The role of niche conservatism in driving diversification of Bertolonia is also analysed and discussed in the light of its historical distribution. We estimated the age of the diversification events, gathered the climatic envelopes of species and clades, generated bioregions for the Atlantic Forest and reconstructed the ancestral areas of speciation for the genus. Our analysis subdivided the Atlantic Forest in five subareas, three of them in the northern and two in the southern Atlantic Forest. We also recovered a deep north/south divergence of the Atlantic Forest in the Oligocene (c. 30 Mya) followed by subsequent local radiations in both regions and a south-eastern/southern division in the Miocene. Later diversification happened mostly from the Mid-Miocene to Pliocene/Pleistocene with several dispersal events, mostly between neighbouring areas. We corroborated this assumption demonstrating that closely related lineages tend to occur in habitats with similar climatic conditions, mainly related to temperature. Our analyses on Bertolonia effectively captured relatively old historical events in the Atlantic Forest, such as the north/south division in the Oligocene and south/south-eastern split in the Miocene, but also recent ones, such as climatic fluctuations and forest fragmentation in the Quaternary. We indicate here for the first time that, for some organisms, the well-known north/south split of the Atlantic Forest could be older than expected. Recent radiation events occurred mainly on a regional basis after this deep division of the domain and the subclades that were recovered showed a significant climatic niche conservatism.

    Abstract: We describe and illustrate Bertolonia hirsutissima, a new species from the state of Bahia in Brazil. It has been collected only three times in one locality in the municipality of Wenceslau Guimarães. The new species can be recognized by the combination of bullate/foveolate leaf surfaces, hirsute petioles (these also with sessile and stalked glands), long sepals with crenulate-denticulate and long ciliate margins, and anthers lacking appendages and dehiscing through an extrorse apical pore.

    Abstract: A new species of Miconia section Miconia, subsection Seriatiflorae from the Brazilian Amazonian region is described. Miconia renatogoldenbergii has a wide distribution in areas of savanna and forest understory in the states of Pará, Mato Grosso and Rondônia. It is similar to M. punctata as both species have chartaceous leaves with rusty lepidote indument on the abaxial surface. The new species can be distinguished by its mucronate leaf apex, a thyrse with short scorpioid branches, and subulate anthers, with round apex, dehiscent through an apical pore and with cordate connective appendages.
