Floral symmetry

[Left] Normal Streptocarpus flower (zygomorphic or mirror-symmetric), and [right] peloric (radially symmetric)  flower on the same plant
Wurmbea stricta, its tepals in actinomorphic arrangement
Satyrium carneum. Ground orchid with typical zygomorphic floral anatomy
 Digitalis purpurea (common foxglove) displaying an aberrant peloric terminal flower and normal zygomorphic flowers

Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts.

Uncommonly, flowers may have no axis of symmetry at all, typically because their parts are spirally arranged.
