Invasional meltdown: pollination of the invasive liana Passiflora tripartita var. mollissima (Passifloraceae) in New Zealand

Banana passionfruit (Passiflora tripartita var. mollissima) is an invasive vine in New Zealand where it lacks its natural hummingbird pollinator. We investigated the mating system and reproductive traits that facilitate its spread in the Marlborough Sounds. Flower observations revealed that visitors were almost exclusively introduced honeybees and bumblebees, indicating an invasive mutualism.
