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.
The fragrant flowers, which are borne in spring to early summer, are white, 1–2 cm (3 ⁄ 8 – 3 ⁄ 4 in) diameter, with a tube-like corolla opening out into five petal-like lobes. The white, rotate actinomorphic flowers have a calyx formed by five narrow, smooth, reflexed sepals 2−5 mm, much shorter than the corolla tube. The latter has ...
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. [2]
The flower color varies from darker shades of purple through soft, pinkish purple, and a white flowering form exists as well. The actinomorphic flowers have five reflexed petals and an elevated central crown. After blooming, green follicles, approximately 12 cm (4 + 3 ⁄ 4 in) long, are produced that when ripe, split open
I’m not even going to attempt to explain the first “actinomorphic” or the last “zygomorphic.” Or that the flowers are “radially symmetrical” and that the flowers have 20 to 30 tepals ...
General floral formula of the Liliacaeae: Flowers actinomorphic or slightly zygomorphic 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.

Stems have four faces; one set is broader and convex, the other set is narrower, concave. Flowers are actinomorphic (radially symmetrical), 2–3 cm in diameter, pink-purple to white, (yellow in R. lutea), petals 4, sepals 4, stamens 8. Bright yellow anthers are long and curved counterclockwise.
