Sympetalae

From Wikipedia, the free encyclopedia

Sympetalae, meaning “with fused petals”, is a descriptive botanical name, used in the Engler system (and derived systems, such as the Wettstein system) 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.

In its circumscription, but not in its internal taxonomy, this group corresponds closely to the Asteridae in the Cronquist system and to the asterids in the APG II-system.
