Plants that have male flowers (or staminate flowers) on one plant, and female flowers (or pistillate flowers) on another plant Therefore, a pollinating male plant bears no fruits or seeds, whereas a female plant may have fruits, if pollination and favorable environmental conditions occur Examples of dioecious trees include Green Ash and Osage Orange An advantage of dioecious trees is that seedless males can be selected and propagated
Species in which male and female reproductive organs are found on separate plants Most hollies (genus Ilex) are dioecious; female plants will only bear fruit when a male grows nearby, and male plants do not bear fruit
Plants in which the male reproductive organs occur in one individual and the female organs in another
