perfect flower
Quick Summary
An imperfect flower is a flower that lacks either male or female reproductive organs. These flowers are also referred to as diclinous.123
A perfect flower, conversely, possesses both male (stamens) and female (carpels) reproductive organs. These are also known as monoclinous flowers.142
Flowers are the reproductive structures of angiosperms, or flowering plants. They are essentially modified shoots with floral organs attached to a receptacle. These organs include sepals (collectively the calyx), petals (collectively the corolla), stamens (the male parts, collectively the androecium), and carpels (the female parts, collectively the gynoecium). When a flower has both stamens and carpels, it is considered perfect. If it has only stamens, it is staminate, and if it has only carpels, it is carpellate. Flowers with only one of these sets of organs are considered imperfect.152
