Angiosperms exhibit a great diversity of inflorescence types, such as racemes, panicles, corymbs, and cymes, depending on the number and arrangement of flowers on shoots, and their branching patterns (Benlloch et al., 2007; Endress, 2010).The evolution of inflorescences has attracted the interest of botanists for … Webb6 feb. 2024 · Phylogeny and Evolution of the Angiosperms: Revised and Updated Edition.
