Passiflora

Passiflora Linnaeus. Common name: Passionflower.

Key to Passiflora

A genus of about 525 species, vines, shrubs, and trees, largely of tropical America, with a few species in warm temperate America and Asia.

Glossary (beta!)

ID notes: Passiflora flowers are structurally striking. There are 5 sepals and either 0 or 5 petals; a corona of numerous linear structures is present, arranged in 1-several series. The ovary, 3 styles, and 5 stamens are basally adnate and elevated on an androgynophore. Most species have glands on the leaves which function as extrafloral nectaries; these can be seen as paired glands on the leaf petiole (in all our species except P lutea), and some species also have laminar glands on the leaf blade, near the margin.
