Passiflora tridactylites was described by J. D. Hooker in 1851. At the time he
actually described what he considered to be three distinct species: P. lineariloba,
P. tridactylites, and P. puberula. He based his descriptions primarily upon
vegetative morphology. He described P. lineariloba as a slender vine having
deeply trilobed leaves with long, very narrow lateral lobes that are broadly
diverging. Hooker apparently did not see the flowers of P. lineariloba because he
does not describe them and the type specimen is sterile. Passiflora tridactylites
was described as having deeply trilobed leaves with subcordate bases and
shorter, linear-oblong lateral lobes. Hooker described the flowers of this species
as large (3/4 inch in diameter), with five linear, obtuse sepals with the ovary
possessing a greatly elongated "pedicel" (androgynophore), and coronal
filaments that are subequal to the sepals. Passiflora puberula was described as
being covered in short, microscopic hairs and possessing trilobed leaves with
cuneate bases and shorter, linear-lanceolate lateral lobes. Hooker goes on to
describe the flowers, which possess five narrowly linear sepals that are
pubescent, and fruits, which are ovate-oblong; though not mentioned in his
description, the lectotype specimen of P. puberula possesses a very long
androgynophore. Lawesson (1988) differentiated between P. suberosa and P.
tridactylites, but did not list the synonyms of either species in his treatment.
Because Hooker based his description of P. tridactylites on both vegetative and
reproductive material with a detailed description of the flower, I chose to use that
name for the Galápagos entity, with P. lineariloba and P. puberula treated as
synonyms. Though the type specimen of P. lineariloba is sterile, vegetatively
