Good to know
Flora area limits. Each flora covers its own region only: Flora of North America stops at the Mexican border, and Flora of China covers China; do not read a treatment as the plant’s whole world range.
Introduced taxa. Flora of North America treats naturalised introduced species and says so; carry that status with the distribution it gives.
