 Welcome to the Checklist of the Vascular Plants of the Americas (VPA) website!

                               ¡Bienvenido ~ Bem-vindo ~ Bienvenue!

The Vascular Plants of the Americas (VPA) website contains the first integrated assessment of all known native species of vascular plants in the New World. It contains 124,993 species in 6,227 genera, and 355 families (Dec. 2017) and additions since 2018. The species number corresponds to about 33% of the 383,671 vascular plant species known globally.

The list includes a collated dataset of accepted names of native vascular plant species from 12 geographic areas*: North America north of Mexico (continental United States, Canada, surrounding islands, and Greenland), Mexico, Central America, Colombia, Venezuela, Guianas (French Guiana, Guyana, Suriname), Ecuador, Peru, Bolivia, Brazil, Southern Cone (Cono Sur: Argentina, Chile, Paraguay, Uruguay), and the West Indies. The list was compiled from published sources by the authors and collaborators including catalogues, checklists, and two large ongoing flora projects, and some unpublished data provided by the authors. (*Trinidad & Tobago added 2018)

This list is a work in progress and updates and corrections are done regularly and posted on this website.

We welcome comments and feedback, and extend an invitation to contributors.
