On the rarity of dioecy in flowering plants
WebOnly ~6–7% of flowering plant species have separate sexes (Renner and Ricklefs, 1995). Despite being relatively uncommon, dioecy has a scattered distribution across the angiosperm phylogeny occurring in ~40% of all angiosperm families.
On the rarity of dioecy in flowering plants
Did you know?
WebDioecy, the coexistence of separate male and female individuals in a population, is a rare but phylogenetically widespread sexual system in flowering plants. While research has concentrated on why and how dioecy evolves from hermaphroditism, the question of why dioecy is rare, despite repeated transitions to it, has received much less attention. … WebGiven the frequent evolution of dioecy and its overall rarity in angiosperms, the view that dioecious species are less evolutionary successful than hermaphrodites has dominated the literature. In his now classic review of plant sex chromosomes, Westergaard (1958) dis-missed dioecy as a “failure” in plants. This view, which
