In Gentianaceae, Oleacese, Apocynacese, Asclepiadacese, Convolvulacese, and many Boraginacese and SolanacesB the corolla is actinomorphic. The Labiatse, Scrophulariacese, Verbenacese, Acanthacese, Lentihulariacese, and some genera of Boraginacese and Solanacese bear distinctly zygomorphic flowers. In the Ash genus (Fraxinus), which belongs to the family of Oleacese, the corolla is often entirely suppressed. Most Labiatse have four.
