A flower which cannot be divided into two equal parts along the axis in any way is called asymmetric flower. Like- Kalabati, Orchid, Sarvajaya etc.

There are three types of flowers according to symmetry
(i) Asymmetric: A flower which cannot be divided into two equal parts along the axis in any way is called asymmetric flower. Like- Kalabati, Orchid, Sarvajaya etc.
(ii) Zygomorphic: A flower which can be divided into two equal parts once along the axis is called a symmetrical flower. For example- Beans, Buckwheat, Atsi, Beans, Aparajita etc.
(iii) Actinomorphic: A flower which divides along the axis to produce multiple equal parts is called a polysymmetric flower. For example – dhotura, jaba, brinjal, mustard etc.

A flower which has neither stamens nor pistils is called Cliblinga flower. It beautifies.

Flowers which have both stamens and pistils are called bisexual flowers. For example- Mustard, Dhutura, Jaba etc.

A flower that has stamens or pistils is called unisexual flower. For example, pumpkin, palm, gourd etc.

There are three types of flowers according to sex
(i) Unisexual flower: A flower that has stamens or pistils is called unisexual flower. For example, pumpkin, palm, gourd etc.
(ii) Bisexual flower: Flowers which have both stamens and pistils are called bisexual flowers. For example- Mustard, Dhutura, Jaba etc.
(iii) Cliblinga flower: A flower which has neither stamens nor pistils is called Cliblinga flower. It beautifies.

A flower in which the size, shape and color of the four petals are not the same is called irregular flower. For example – Aparajita, Beans, Buck, Beans etc.

The size, shape and color of the four stanzas of the flower are the same, it is called regular flower. For example – jaba, dhutura, brinjal, mustard etc.

Flowers are of two types according to the similarity of organs
(i) Regular flower: The size, shape and color of the four stanzas of the flower are the same, it is called regular flower. For example – jaba, dhutura, brinjal, mustard etc.
(ii) Irregular flower: A flower in which the size, shape and color of the four petals are not the same is called irregular flower. For example – Aparajita, Beans, Buck, Beans etc.

A flower in which any one of these four parts, corolla, pistil, pistil and stamen, is missing is called incomplete flower. For example, gourd, pumpkin, rosin, red leaf etc.
