Flower sex

Flower sex

Flower sex refers to the presence or absence of androecium and gynoecium within a flower.

1. Perfect or bisexual(monoclinous): When a flower contains both androecium and gynoecium is called perfect flower.

2. Imperfect or unisexual (diclinous): When the flower contains only one of the essential whorls is called Imperfect flower. It is of two types:

i) Staminate flowers: Flowers only with androecium alone are called staminate flowers.

ii) Pistillate flowers: Flowers with only gynoecium are called pistillate flowers.
