The Passifloraceae are a family of flowering plants, containing about 750 species classified in around 27 genera.[1]
They include trees, shrubs, lianas, and climbing plants, and are mostly found in tropical regions. The family takes its name from the passion flower genus (Passiflora) which includes the edible passion fruit (Passiflora edulis), as well as garden plants such as maypop and running pop.
Passiflora vines and Dryas iulia (among other heliconian butterflies) have demonstrated evidence of coevolution, in which the plants attempted to stop their destruction from larval feeding by the butterflies, while the butterflies tried to gain better survival for their eggs.[3]
