Asterales
True, or English, daisy (Bellis perennis).
The two families that contain the vast majority of species within the Asterales order are:
- Asteraceae: This is the largest family in the order, comprising more than 25,000 species.12
- Campanulaceae: This family, which includes the Lobeliaceae, represents the second major group within the order.1
