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:Sambucus australis Cham. & Schltdl. (sabugueiro-do-rio-grande, Caprifoliaceae) é uma planta medicinal descrita apenas na primeira edição da Farmacopéia Brasileira. A espécie é nativa no Brasil, e suas fl ores são utilizadas na medicina popular, na forma de infusão ou decocção, como diuréticas, antipiréticas, antiinfl amatórias, laxativo leve e no tratamento de doenças do aparelho respiratório. Visando elaborar uma monografi a farmacopéica atualizada e comparativa com a de Sambucus nigra L., de origem européia, foram estabelecidos os caracteres botânicos macro e microscópicos, através da metodologia clássica utilizada em morfoanatomia vegetal. São características macroscópicas: fl ores morfologicamente monoclinas; corola de sete a dez milímetros de diâmetro; pétalas com cinco, raro quatro nervuras paralelas; estames curtos e longos; gineceu em regra com cinco lóculos. São características microscópicas: cutícula espessa e estriada; ausência de idioblastos de areia cristalina de oxalato de cálcio; estômatos anomocíticos; brácteas anfi estomáticas; sépalas hipoestomáticas; pétalas anfi -hipoestomáticas; células epidérmicas da face abaxial de sépalas e pétalas retilíneas a sinuosas; células epidérmicas do fi lete alongadas e de paredes retilíneas; tricomas tectores e glandulares de diferentes tipos; brácteas, sépalas e pétalas com mesofi lo homogêneo; sistema vascular representado por feixes colaterais ou agrupamentos de elementos xilemáticos; presença de gotas lipídicas em todas as peças.Unitermos: Sambucus australis, Caprifoliaceae, farmacobotânica, morfoanatomia. (sabugueiro-do-rio-grande, Caprifoliaceae) is a medicinal plant described only in the fi rst edition of Brazilian Pharmacopoeia. This species is native to Brazil, and its fl owers are used in the folk medicine, with diuretic purpose, antipiretic, anti-infl ammatory, mild laxative and to treat respiratory diseases, on infusions or decoctions forms. Aiming at elaborating an updated pharmacopoeical monograph and comparing it with the monograph of Sambucus nigra L., from Europe, it was established the macro and microscopic botanical characters, through the classic methodology used in plant morpho-anatomy. The macroscopic characters are: morphologic monoclin fl owers; corolla with seven to ten millimeters of diameter; petals with fi ve, rarely four parallel veins; shorter and longer stamens; ovary oftenly with fi ve locules. The main microscopic characters are: thickned and striated cuticule; absense of idioblasts with calcium oxalate sandy cristals; anomocytic stomatas; amphystomatic bracts; hypostomatic sepals; amphi-hypostomatic petals; wavy and straight epidermal cells in the lower surface of sepals and petals; fi laments epidermal cells with narrow and straight walls; glandular and non-glandular trichomes of different types; homogeneous mesophyll in bracts, sepals and petals; vascular system represented by both collateral bundles and xylematic elements; volatile and non volatile oil globules in all structures.
Abstract. We review the sixty eight names of plants treated in genera treated or now recognised as Violaceae respectively. We provide lectotypifications for all names, including those previously lectotypified using the published plates that do not qualify as original material. Type localities, previous lectotypifications and current accepted names are provided for all taxa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
