What does dioeciously mean?
Dioeciously is a specialized botanical adverb derived from dioecious, the adjective for a plant species in which individual plants bear either male or female flowers rather than both. It describes reproduction or plant organization in that separated, unisexual arrangement, so “the population reproduces dioeciously” means that staminate and pistillate flowers occur on distinct individuals. The term belongs chiefly to formal botanical and horticultural description; speakers would normally use the more familiar adjective dioecious. Its usefulness is precise: it distinguishes a reproductive system in which male and female flowers are divided between separate plants from systems in which one plant carries both flower sexes. The adverb is uncommon, but it names a significant feature of flowering-plant biology and horticulture. In most descriptions, “dioecious” will sound more natural, while “dioeciously” is most appropriate when an adverb is grammatically required.

Where does dioeciously come from?
The adjective dioecious was borrowed into English from New Latin dioecius, a botanical term derived from Ancient Greek dioikos, meaning “two-houseed.” Greek dioikos was formed from di-, meaning “two,” and oikos, meaning “house.” The English adverb dioeciously was subsequently formed from dioecious with the suffix -ly.
