Brit.

/ˌpɒlɪsᵻˈmɛtrᵻkl/, U.S.

/ˈˌpɑlisəˈmɛtrək(ə)l/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: poly- comb. form, symmetrical adj.

Etymology: < poly- comb. form + symmetrical adj., after German polysymmetrisch (1873 in the passage translated in quot. 1875). Compare monosymmetrical adj., and also later polysymmetric adj.

Botany.

Symmetrical about several axes; spec. = actinomorphic adj.
