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. See more Most flowers are actinomorphic ("star shaped", "radial"), meaning they can be divided into 3 or more identical sectors which are related to each other by rotation about the center of the flower. Typically, each sector might … See more A few plant species have flowers lacking any symmetry, and therefore having a "handedness". Examples: Valeriana officinalis See more Peloria or a peloric flower is the aberration in which a plant that normally produces zygomorphic flowers produces actinomorphic … See more • Patterns in nature • Phyllotaxis • Symmetry in biology • Whorl (botany) See more Zygomorphic ("yoke shaped", "bilateral" – from the Greek ζυγόν, zygon, yoke, and μορφή, morphe, shape) flowers can be divided by only a … See more Actinomorphic flowers are a basal angiosperm character; zygomorphic flowers are a derived character that has evolved many times.

This type of floral arrangement is observed in three types of aestivation namely imbricate, vexillary, and valvate. Irregular or zygomorphic flowers are also known as bilaterally symmetrical.
