Sympetalae Rchb. (1828), meaning “with fused petals”, is a descriptive botanical name used in the Eichler, Engler, and Wettstein systems for a group in the flowering plants. In this group the flowers have a separate calyx and corolla with the petals fused, at least at the base of the corolla, a condition known as sympetaly.
