title: Species documented in a global study of seed dormancy in space and time: taxonomic standardization of 12,743 species to World Flora Online

description: Zhang et al. (2022) compiled global distribution records for seed dormancy of 12,743 species and their phylogeny to explore the biogeographic patterns, environmental drivers, and evolutionary transitions between seed dormancy and nondormancy.

Here I provide a dataset where these species were standardized to World Flora Online (Borsch et al. 2020; taxonomic backbone version 2023.12) by matching names with those in the Agroforestry Species Switchboard (Kindt et al. 2025; version 4). Species for which no matches could be found were standardized with the WorldFlora package (Kindt 2020), using similar R scripts and the same taxonomic backbone data as those used to standardize species names for the Switchboard.

Additional fields indicate whether a species was flagged as a tree in the Switchboard, and the lifeform obtained from the World Checklist of Vascular Plants (Govaerts et al. 2021, version 11).
