Perfect and Imperfect

The terms perfect and imperfect as pertaining to flowers relates to their sexuality. Flowers are the sexual organs of a plant, and they may contain male (stamens), female (pistils), or both parts. A plant is said to be perfect if it possesses both male and female equivalent parts. If a flower has only male, or only female structures, it is said to be imperfect.

Pistillate and Staminate

A flower is pistillate if it possesses only pistils, which are a plant's female reproductive structures. If it possesses only stamens (the male reproductive structures), it is called staminate.

Dioecious: Having unisexual reproductive units (flowers, conifer cones, or functionally equivalent structures) occurring on different individuals; from Greek for "two households".
