A flower is a short-shoot that serves sexual reproduction. It typically consists of male (stamina) and female (carpels) reproductive organs and perianth-leaves. All floral organs are here referred to as 'floral-leaves'. They are mostly arranged in whorls. A stamen corresponds to a microsporophyll and a carpel to a megasporophyll. Therefore, a flower may also be considered as a strobilus of limited growth.
