title: Seed Information Database: taxonomic standardization of 54,856 taxa to World Flora Online or the World Checklist of Vascular Plants

description: The Seed Information Database (SER, INSR & RBGK 2023) provides user-friendly access to information on seed weight, storage behaviour, germination requirements, and other traits for more than 50,000 plant taxa.

Here I provide a dataset where these taxa were standardized to World Flora Online (Borsch et al. 2020; taxonomic backbone version 2023.12) or the World Checklist of Vascular Plants (Govaerts et al. 2021, version 11) by matching names with those in the Agroforestry Species Switchboard (Kindt et al. 2025; version 4). Taxa 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 (WFO; WCVP when no acceptable match was found) 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).
