P. foetida var. gossypiifolia is thought to be carnivorous because the sticky bracts surrounding the buds trap insects. When the flower opens, the bracts part, and when the flower closes back up, the bract comes together again. The bracts will remain around developing fruit and eventually fall off as the fruit begins to ripen.

P. foetida var, gossypiifolia is one of the few passies that germinate quickly from seed.

The "Powers that be," GRIN and Kew Gardens, decided that Vigna caracalla, aka Corkscrew Vine, and Vigna phaseolus caracalla were the same species - Vigna caracalla. The flowers and buds are totally different in form.

The Snail Vine is always lavender/purple.

The Corkscrew Vine is white and lavender/purple morphing into amber as the flower ages.
