Of particular interest are the clones of the various entities of P. suberosa and
P. pallida (Fig. 4.5). Sequences cloned from a single individual of Passiflora
suberosa ssp. suberosa from Haiti are found in two different clades, with two
clones (“a” and “b”) falling within a moderately supported clade containing other
members of the subspecies from the Caribbean and the other two (“c” and “d”)
forming a group in the strict consensus tree that is positioned sister to most of the
taxa in the supersection. In addition, cloned entities of Passiflora suberosa ssp.
litoralis from the states of Puebla and Veracruz, México are found in separate
clades. The clones of the “sub. w/ pall. aff. USA(FL)” entity from Florida occur in
both the well-supported P. pallida clade (“a” and “c”) and the clade containing P.
suberosa along with the rest of the species from the supersection (“b” and “d”),
indicating that there is gene flow, likely resulting from hybridization, between P.
suberosa and P. pallida.
