Flora of Brazil: Elaeocarpaceae

Abstract The major objective of this study was to contribute to the Flora of Brazil 2020, which is part of the targets established by the Conference of the Parties of the Convention’s signatory countries on Biological Diversity. The development of the Brazilian Flora is coordinated by the Rio de Janeiro Botanical Garden, under the direction of the Ministry of Environment of Brazil and involves national and international research institutions. In this work a floristic survey of the species of Elaeocarpaceae that occur in Brazil was made, as well as the elaboration of a flora for the family, with identification keys, descriptions of genera and species, taxonomic comments and geographical distribution. The main national herbaria were consulted and analyzed, either in person or through loans. The nomenclature types deposited in national and foreign herbaria were analyzed. Two genera were recognized: Crinodendron with one species and Sloanea with 43. Thus, 44 valid names, 57 synonyms and one new species for the family in Brazil were recognized. In addition, seven lectotypes, and 16 new synonyms were assigned.

摘要 本研究的主要目标是为《巴西植物志2020》的编撰工作提供支撑，该项目是《生物多样性公约》缔约方大会为各缔约国设定的工作目标之一。《巴西植物志》的编撰工作由巴西环境部指导下的里约热内卢植物园统筹协调，汇聚了国内外多家科研机构参与。本研究针对巴西境内分布的杜英科（Elaeocarpaceae）物种开展了系统的植物区系调查，并完成了该科的专属植物志编撰，内容涵盖分类检索表、属与物种形态描述、分类学评述以及地理分布信息。研究团队通过实地查阅及标本借阅的方式，对巴西主要国家级标本馆进行了调研与分析；同时对存放于国内外标本馆的模式标本展开了系统性研究。本次研究共确认2个有效属：杯萼木属（Crinodendron）含1个物种，猴欢喜属（Sloanea）含43个物种。据此，巴西境内杜英科共计确认44个有效学名、57个异名以及1个新种。此外，本研究指定了7份后选模式标本，并确立了16个新异名。
