Botanical term (diocesan) for plants that have either only male or only female sexual organs - so to speak "on two different houses" (plants). For fertilization it is necessary that the male seeds (pollen) reach the female flowers. This happens in different ways, for example by wind or bees. As a rule, wild vines are dioecious; the cultivated vine, however, is monoecious and has bisexual hermaphrodites. See also under flower and vine systematics.
