Describing flowers or structures that exhibit bilateral symmetry, with parts arranged so that only one plane can divide the structure into two mirror-image halves. This creates an asymmetrical appearance with distinct upper and lower portions.
From Greek 'zygon' meaning yoke or pair and 'morphe' meaning form, literally meaning 'yoke-shaped.' The term was introduced in the 19th century to describe the bilateral symmetry characteristic of many specialized flowers.
Zygomorphic flowers are evolution's masterpiece of precision engineering - like orchids and snapdragons, they've evolved specific asymmetrical shapes that perfectly match their pollinator's body, creating an exclusive relationship that benefits both species!
