Sinopse do gênero Jacquemontia Choisy (Convolvulaceae) no Estado de São Paulo, Brasil: notas nomenclaturais, taxonômicas e geográficas

ABSTRACT (Synopsis of the genus Jacquemontia Choisy (Convolvulaceae) in São Paulo State, Brazil: nomenclatural, taxonomic and geographical notes). This taxonomic study is part of the project “Flora Fanerogâmica do Estado de São Paulo”. In São Paulo State, Jacquemontia is represented by 14 species and two varieties. These species can be distinguished mainly through their habit, type of trichomes, inflorescences and sepals. Identification key, illustrations, photographs, synonymy, typification, geographical distribution, taxonomic comments, and conservation status are presented for all the studied species. Additionally, eight lectotypes and two neotypes are proposed. Finally, we classified one species as presumably extinct, one as vulnerable, and one as near threatened in São Paulo State.

摘要：巴西圣保罗州旋花科（Convolvulaceae）打碗花藤属（Jacquemontia Choisy）类群综述——命名学、分类学与地理学注解。本项分类学研究系《圣保罗州显花植物志（Flora Fanerogâmica do Estado de São Paulo）》项目的组成部分。圣保罗州境内分布有打碗花藤属植物14种及2变种。该属物种主要可凭借生长习性、毛被类型、花序及花萼特征加以区分。本研究为所有收录物种提供了分种检索表、形态插图、实物照片、异名名录、模式指定说明、地理分布数据、分类学评述及保护等级评估。此外，本研究共指定8个后选模式标本（lectotype）与2个新模式标本（neotype）。最后，研究团队将圣保罗州境内的1个物种评定为疑似灭绝，1个物种评定为易危，1个物种评定为近危。
