The Family Ranunculaceae is commonly referred to as the Buttercup family due to the yellow, cup-shaped flowers of many species in the family. Other common synonyms for this family include the Crowfoot family, which refers to the complex, branched arrangements of the leaves of many plants in the family, and the Pasqueflower family, named for the genus Pulsatilla which produces striking, purple, bell-shaped flowers in early spring. The Family Ranunculaceae includes over 2,000 species, many of which are valued for their ornamental value in garden settings. Despite their beauty, many species in the family are also toxic to humans and animals if ingested.
