The Passifloraceae are a family of flowering plants that includes about 530 species divided into around 18 genera. This family includes trees, shrubs, vines, and climbing plants, primarily found in tropical regions. The family is named after the genus of passion flowers (Passiflora), which includes the edible passion fruit (Passiflora edulis) as well as garden plants like Maypop and Running Pop. The earlier Cronquist classification system placed this family in the order Violales, but under more modern classification systems, such as those proposed by the Angiosperm Phylogeny Group, it is included in the Malpighiales.
