The most derived large clade of eudicots is the asterid clade, which contains plants such as sunflower, periwinkle, petunia, and morning glory.
Currently, asterids have the greatest number of species, but they are grouped into two small orders and two groups of orders, lamiids, also called euasterids I and campanulids( euasteridsII
many asterids have iridoid compounds, which occurs only rarely outside this group.
