Flowers actinomorphic and hermaphrodite with 6 undifferentiated tepals in two whorls of three, the same number and arrangement of stamens, and a superior ovary with 3 fused carpels. Individual species and genera may have more or less derived formulas.
Most flowers are actinomorphic ("star shaped", "radial"), meaning they can be divided into three or more identical sectors which are related to each other by rotation about the center of the flower. Typically, each sector might contain one tepal or one petal and one sepal and so on.
A foxglove with a peloric flower. (Digitalis purpurea 'monstrosa')A peloric foxglove (Digitalis purpurea) flowerPelorism is the term, said to be first used by Charles Darwin, for the formation of 'peloric flowers' [1] which botanically is the abnormal production of radially symmetrical (actinomorphic) flowers in a species that usually produces bilaterally symmetrical (zygomorphic) flowers.

By contrast, the Netherlands is the leading international producer, to the extent of 4 billion bulbs per annum. Of these, 53% are used for the cut flower market and the remainder for the dry bulb market. Of the cut flowers, 57% are used for the domestic market in the Netherlands and the remainder exported.

Crinum stuhlmannii infructescences Detail of Crinum × amabile flower with stamens inserted at the throat of the perianth tube Germinating Crinum seed . The bisexual, [5] [3] sessile or pedicellate, [5] [4] zygomorphic or actinomorphic flowers [4] are borne one umbellate or solitary inflorescences [3] [4] with solid scapes.
Each flower has five white or rarely pinkish-white to purplish petals. [3] The central flowers of the umbel have radial symmetry (actinomorphic), while the flowers around the perimeter of the umbel have bilateral symmetry (zygomorphic) since the outermost petals are enlarged.

Flowers have radial symmetry (actinomorphic), [1] and are borne in heads that are cymes or racemes, or are solitary in axils. [6] They are perfect (bisexual), with a synsepalous, five-lobed calyx united into a tube at the base. [1] [6] Inflorescences are terminal or axillary. Five petals are united into a tube with four or five epipetalous ...
