Interaction between floral rewards and floral symmetry shapes diversification dynamics in Amazonian trees

open access: yesNew Phytologist, Volume 248, Issue 6, Page 3297-3311, December 2025.
Summary Floral zygomorphy, or monosymmetry, is thought to have a positive effect on the diversification rates of angiosperms, but its true impact is still an open topic. Given the controversy surrounding this matter, our study evaluates whether rewards such as nectar and pollen produced by floral structures evolve in correlation with floral symmetry ...
