"Gender and Sexual Dimorphism in Flowering Plants" is a scholarly book that explores the evolution of gender dimorphism and sexual dimorphism in flowering plants. While most flowering plant species are hermaphroditic, gender dimorphism has developed in many cases and is found in nearly half of all angiosperm families as well as in about 10% of flowering plant species. The book provides a comprehensive analysis of the theoretical and empirical research on these topics and sheds light on the lesser-known subject of sexual dimorphism. It combines current assessments of both forms of dimorphism and offers a valuable update on previous work in this area. The editors, Monica A. Geber, Todd E. Dawson, and Lynda F. Delph, aim to highlight the widespread nature of sexual dimorphism in plants and dispel doubts about its relevance. This book is an important resource for researchers and students studying the evolution and biodiversity of plants.
