英文摘要

Gynochthodes umbellata (Rubiaceae) is differentiated among populations in sexual system. The populations occurring in the Bonin Islands are characterized by an androdioecious sexual system, which is rare found in angiosperm, while those distributed in the Ryukyu Islands are dioecious. I investigated the evolutionary transitions among different sexual systems within this plant group, and the ecological factors associated with these different systems from the viewpoint of phylogenetics and pollination ecology. The phylogenetical data showed that the Gynochthodes populations in the Bonin Islands did not form a clade with the populations distributed in the Ryukyu Islands, suggesting that they are distantly related each other. It was also suggested that the androdioecious sexual system found in the Bonin Island populations may have evolved from dioecy, since the related species including G. umbellata and its allies are functionally dioecious
