Pronunciation: /ˌzʌɪɡə(ʊ)ˈmɔːfɪk/


(Of a flower) having only one plane of symmetry, as in a pea or snapdragon; bilaterally symmetrical. Compare with actinomorphic.
Example sentences
  • The gynoecium is on the median plane of these zygomorphic flowers and not oblique as described in taxonomic literature.
  • Alternatively, the gynoecium of a zygomorphic flower can be on the median plane of the flower, but the entire flower can be oblique to the axillary plane.
  • It is a family of predominantly annual and perennial herbs with a semi-succulent habitus, which can be easily distinguished from other balsaminoids by its zygomorphic flowers with a spurred petaloid sepal.



Example sentences
  • Growth of the corolla and androecium show a dorso-ventral asymmetry that also results in zygomorphy.
  • In addition, as suggested by Leins and Erbar, the zygomorphy of the flowers found in the Lobelias makes them more effective for pollination than actinomorphic flowers.
  • Zygomorphic flowers were mostly found among hummingbird- and medium-large bee-pollinated species and, in fact, zygomorphy is largely known as a visual attractant for some groups of pollinators such as bees and hummingbirds.
