Polygamous breeding system identified in the distylous genusPsychotria:P. manillensisin the Ryukyu archipelago, Japan

Abstract: The evolutionary breakdown of distyly has been reported in many taxa, and mainly involves a shift toward monomorphism or dioecism. However, a shift toward monoecism has not been reported in distylous species. Psychotria (Rubiaceae), one of the world largest genera, consists of distylous species and their derivatives. In our preliminary study, however, we identified some monoecious individuals in a population of Psychotria manillensis. To understand the breeding system and reproductive biology of P. manillensis… Show more

“…Actually, recent studies indicate polygamous populations of Psy. manillensis, with different flower morphologies and breeding behaviors (Watanabe et al 2020). Thus, intermediate stages and self-interference may have played important roles on the evolution of unisexual flowers, as previously proposed (Casper & Charnov 1982;Charlesworth 1989;Charlesworth & Morgan 1991).…”
