Linnaeus described several species which are now considered to be just one. Passiflora pallida L. is now considered a synonym of P. suberosa. Killip argued in Passifloraceae 1: 88-97 in 1938 Although strict adherence to the rules of page priority would require the use of the name P. pallida, it seems best to apply P. suberosa to this species because (1) the form with 3-lobed leaves is much the commoner and has the wider distribution; (2) it was represented in the Linnean Herbarium by a specimen which Linnaeus had at hand in 1753; and (3) it is the name in general use.
