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.
