    The caatinga is a deciduous and xerophilous vegetation that covers large areas in Brazil. An irregular rainfall with a marked dry period is a characteristic feature. This paper represents the first contribution to the knowledge of the bryoflora from caatinga vegetation in the State of Bahia. The survey was carried out in several areas from Bahia in which eigthteen species of bryophytes were found (15 mosses and 3 liverworts). The bryoflora from caatinga is composed mainly of generalists and xerophilous taxa, but even some hygrophilous species can be found. A number of species including Hyophiladelphus agrarius, Hyophila involuta, Calymperes palisotii ssp. richardii, Bryum argenteum, Entodontopsis leucostega, Octoblepharum albidum, Frullania ericoides also occur in other vegetation types. However, there are a number of species restricted to this type of vegetation, such as Helicophyllum torquatum and Riccia vitalii, at least in Bahia. Most moss species were acrocarpous with erect and short (short-turf) growth-form, whereas the foliose hepaticae were of incubous, and thallose forms

    This paper represents an additional contribution toward the knowledge of a bryophyte flora of Chapada Diamantina National Park in the State of Bahia, Brazil, in which are reported 27 species of mosses belonging to 22 genera and 14 families, and four species of liverworts belonging to four genera and three families. Most of these species seem to be restricted to this high altitude geomorphological complex area

The most represented families were Calymperaceae (12 species and three varieties - 40.5%), Fissidentaceae (seven species  - 18.9%) and Bryaceae (six species  - 16.2%). The most representative genera were Fissidens (seven species) and Syrrhopodon (five species), and the most frequent species were Calymperes lonchophyllum Schwägr. (49 occurrences), Syrrhopodon prolifer var. scaber (Mitt.) W.D. Reese (20 occurrence), Leucobryum martianum (Hornsch.) Hampe ex Müll. Hal. (16 occurrences) and Leucoloma serrulatum Brid. (10 occurrences). Among the bryocenological groups 24 were corticicolous, 19 epixilics, 15 rupicolous, six terricolous, four termiticolous, being 18 species exclusive (50%) and 18 (50%) species shared different substrates.Durante o estudo das briófitas da Reserva Ecológica da Michelin, situada no município de Igrapiúna, BA, foram reconhecidos 36 táxons infragenéricos (33 espécies e três variedades) distribuídos em 16 gêneros e sete famílias. As famílias mais bem representadas quanto ao número de táxons infragenéricos foram Calymperaceae (12 espécies e três variedades - 40,5%), Fissidentaceae (sete - 18,9%) e Bryaceae (seis - 16,2%). Fissidens foi o gênero com maior número de espécies (sete), seguido por Syrrhopodon (cinco). As espécies mais freqüentes foram Calymperes lonchophyllum Schwägr. (49 ocorrências), Syrrhopodon prolifer var. scaber (Mitt.) W.D. Reese (20 ocorrências), Leucobryum martianum (Hornsch) Hampe ex Müll. Hal (16 ocorrências) e Leucoloma serrulatum Brid. (10 ocorrências). Quanto à distribuição das espécies entre os grupos briocenológicos, 24 foram corticícolas, 19 epixílicas, 15 rupícolas, seis terrícolas e quatro termitícolas, sendo que 18 espécies foram exclusivas (50%): seis corticícolas, quatro epixílicas, quatro rupícolas, três terrícolas e uma termitícola, enquanto que 18 (50%) compartilharam mais de um substrato

    O levantamento de musgos realizado em uma área de Mata Atlântica no município de Santa Terezinha, Bahia, resultou em flora rica, com 61 espécies pertencentes a 23 famílias e 46 gêneros. Sematophyllaceae (sete spp.), Orthotrichaceae (seis spp.), Pilotrichaceae (cinco spp.), Calymperaceae (cinco spp.), Leucobryaceae (cinco spp.) e Meteoriaceae (quatro spp.) apresentaram maior riqueza específica. Actinodontium integrifolium (Broth.) Churchill e Calymperes venezuelanum (Mitt.) Broth. ex Pittier constituem novos registros para o Brasil. Ectropothecium leptochaeton (Schwaegr.) W.R. Buck, Eulacophyllum cultelliforme (Sull.) W.R. Buck & Ireland, Fissidens santaclarensis Thér., Lepidopilidium portoricense (Müll. Hal.) H.A. Crum & Steere, Mittenothamnium reptans (Hedw.) Card., Orthostichella pentasticha (Brid.) W.R. Buck, Pilotrichella flexilis (Hedw.) Ångstr., Porotrichum mutabile Hampe e Thuidium tomentosum Schimp. são novas ocorrências para a Bahia. Houve predomínio de táxons de distribuição neotropical. A comunidade corticícola foi predominante com 70% das espécies, seguida da epíxila, com 23%. A brioflora do fragmento mostrou-se rica já que corresponde a 24% do total de briófitas atualmente conhecido no Estado

    Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

    International audienceThe 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
