美洲维管植物的分类已有数百年的历史，但直到最近几十年才有可能对整个植物群进行概述。我们提出了一个综合评估所有已知的原生物种的维管植物在美洲。在过去25年中编制的12份区域和国家清单，包括两个正在进行的大型植物群项目，被合并为一份清单。我们的公开检索清单包括124，993种，6227属和355科，相当于全世界已知的383，671种维管植物的33%。在过去的25年里，美洲平均每年增加744个新物种描述，我们可以预计总数将达到约15万个。
The cataloging of the vascular plants of the Americas has a centuries-long history, but it is only in recent decades that an overview of the entire flora has become possible. We present an integrated assessment of all known native species of vascular plants in the Americas. Twelve regional and national checklists, prepared over the past 25 years and including two large ongoing flora projects, were merged into a single list. Our publicly searchable checklist includes 124,993 species, 6227 genera, and 355 families, which correspond to 33% of the 383,671 vascular plant species known worldwide. In the past 25 years, the rate at which new species descriptions are added has averaged 744 annually for the Americas, and we can expect the total to reach about 150,000.
