Abstract  A revised key to New Zealand indigenous and naturalised species of Passiflora is presented, and this resolves previous difficulties with the identification of P. mixta and P. mollissima of subgenus Tacsonia. Particular attention is given to this subgenus as there have been recent taxonomic changes to naturalised species that originate from South America and most are serious pest plants in New Zealand. The names P. tarminiana and P. tripartita var. azuayensis are applied to New Zealand plants for the first time, and P. tripartita var. mollissima is a new rank for plants previously known as P. mollissima. These taxa occur throughout New Zealand. P. mixta sens. str. is considered to be restricted to the Waitakere Ranges, North Auckland, and Kenepuru Sound, Marlborough, and many of the plants hitherto assigned to that species are treated as P. tarminiana.
