The global spectrum of plant form and function dataset: taxonomic standardization of 45,955 taxa to World Flora Online version 2023.12

The global spectrum of plant form and function dataset (Diaz et al. 2022; Diaz et al. 2016; TRY 2022, accessed 15-May-2025) provides mean trait values for (i) plant height; (ii) stem specific density; (iii) leaf area; (iv) leaf mass per area; (v) leaf nitrogen content per dry mass; and (vi) diaspore (seed or spore) mass for 46,047 taxa. Here I provide a dataset where the taxa covered by that database 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). 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 as those used to standardize species names for the Switchboard. Where still no matches could be found, taxa were matched with those matched previously with a harmonized data set for TRY 6.0 (Kindt 2024). References Díaz, S., Kattge, J., Cornelissen, J.H.C. et al.
