Definition of actinomorphic in English: actinomorphicadjective ˌaktɪnə(ʊ)ˈmɔːfɪkˌaktənōˈmôrfik Biology Characterized by radial symmetry, such as a starfish or the flower of a daisy. 〔生〕辐射对称的（如海星或雏菊花）。比较ZYGOMORPHIC Compare with zygomorphic Example sentencesExamples - This group is composed by eight species belonging to four families with nectarless, dish-shaped and actinomorphic flowers, which are showy, and yellow- or pink-colored.
- The large, showy flowers are actinomorphic, with a bowl-shaped corolla made up of 5-8 pinkish-red petals.
- The actinomorphic, tubular flowers of both species are pale blue to mauve, with epipetalous anthers.
- Determining the orientation of an actinomorphic flower seems impossible in ebractate taxa.
- Flowers are usually showy, bisexual and actinomorphic or nearly so.
Derivativesnoun Biology Look for an elongate floral axis, numerous parts that are spirally arranged, lack of differentiation between calyx and corolla, actinomorphy (regular flowers), and lack of connation (fusion of like parts) and lack of adnation (fusion of unlike parts). Example sentencesExamples - The presence of five stamens is always associated with actinomorphy (radial symmetry) of the corolla (Ramonda, Thamnocharis, Bournea, Tengia, Conandron, Bellonia, Napeanthus p.p.).
- We find strong support for floral integration and its relation with floral morphology (actinomorphy vs zygomorphy) and for a decoupling of floral and vegetative traits, but no evidence that modular integration varies with floral morphology.
- If all parts are equally spaced around the centre, the flowers are radially symmetrical, a condition termed actinomorphy.
- According to the theory, the primeval features are: actinomorphy, hermaphroditic polymer flower with an apocarpous gynoeceum.
