The Sunda-Sahul Convergence Zone, defined here as the area comprising Australia, New Guinea, and Southeast Asia (Indonesia to Myanmar), straddles the Sunda and Sahul continental shelves and is one of the most biogeographically famous and important regions in the world. Floristically, it is thought to harbour a large amount of the world's diversity. Despite the importance of the area, a checklist of the flora has never before been published. Here we present the first working checklist of vascular plants for the Sunda-Sahul Convergence Zone. The list was compiled from 24 flora volumes, online databases and unpublished plot data. Taxonomic nomenclature was updated, and each species was coded into nested biogeographic regions. The list includes 60,415 species in 5,135 genera and 363 families of vascular plants. This is the first species-level checklist of the region and presents an updated census of the region's floristic biodiversity. The checklist confirms that species richness of the SSCZ is comparable to that of the Neotropics, and highlights areas in need of further documentation and taxonomic work. This checklist provides a novel dataset for studying floristic ecology and evolution in this biogeographically important region of very high global biodiversity.
巽他-萨胡尔汇聚区在此定义为包括澳大利亚、新几内亚和东南亚（从印度尼西亚到缅甸）的区域，横跨巽他和萨胡尔大陆架，是世界上生物地理学方面最著名且最重要的区域之一。从植物区系角度来看，人们认为该区域蕴藏着世界上大量的生物多样性。尽管该区域很重要，但此前从未发布过一份植物区系清单。在此，我们呈现了巽他-萨胡尔汇聚区维管植物的首份实用清单。这份清单是根据24卷植物志、在线数据库以及未发表的样地数据汇编而成的。更新了分类命名法，并将每个物种编码到嵌套的生物地理区域中。该清单包括5135个属、363个科的60415种维管植物。这是该区域首个物种级别的清单，呈现了该区域植物区系生物多样性的最新普查情况。这份清单证实了巽他-萨胡尔汇聚区的物种丰富度与新热带地区相当，并突出了需要进一步记录和分类学研究的领域。这份清单为研究这个全球生物多样性极高的生物地理学重要区域的植物区系生态学和进化提供了一个全新的数据集。
