The Boraginaceae and Hydrophyllaceae
Members of the Boraginaceae and Hydrophyllaceae have radially symmetrical flowers arranged in coiled cymes. Sometimes the coils are obvious.
Sometimes the coils are so tight that it is difficult to see that branches of the inflorescence are coiled.
Sometimes the coil is so loose that you have to look closely to notice that the youngest flower bud(s) are tucked up under (or coiled under) the older flowers.
Plants in the Boraginaceae have ovaries are deeply lobed, forming nutlets at maturity. Plants in the Hydrophyllaceae have ovaries that are not deeply lobed, forming a capsule at maturity.
Check your understanding:
The flowers themselves have five stamens that are epipetalous (that is, they are fused to the petals).
Some species may have corolla appendages or calyx appendages.
