Genus Passiflora Family Passifloraceae

Description: Herbaceous or woody climbers with simple axillary tendrils.

Leaves simple and lamina palmately lobed or rarely unlobed [or leaves compound]; petiole at least half as long as lamina, commonly 2–4 raised glands present; stipules rarely persistent, mostly linear and small on native species, sometimes leafy or absent.

Flowers bisexual, axillary, mostly 1 or 2 together, sometimes more. Sepals and petals often highly and similarly coloured. Corona composed of outer appendages and mostly a flat or folded inner corona. Nectariferous disc often at the base of the androgynophore. Stamens mostly 5, on androgynophore, filaments free, at first erect, later usually reflexed; anthers versatile.

Fruit a berry.


Distribution and occurrence: World: c. 400 species, mainly America, some Asia, Australia, & Madagascar (1 species). Australia: 12 species (3 species native), all States except S.A.

*Passiflora coccinea Aubl. is known from one collection from an old garden north of Coffs Harbour (NC), it does not appear to be fully naturalized. It has rounded, crenate leaves that are densely pubescent on lower surface, 5–10 cm long and 4–6 cm wide. Flowers up to 8 cm diam. with reflexed deep red petals.
