Angiosperm flowers reached their highest morphological diversity early in their evolutionary history
New Phytologist, Volume 241, Issue 3, Page 1348-1360, February 2024.Summary Flowers are the complex and highly diverse reproductive structures of angiosperms. Because of their role in sexual reproduction, the evolution of flowers is tightly linked to angiosperm speciation and diversification. Accordingly, the quantification of floral morphological diversity (disparity) among angiosperm subgroups and through time may ...
