Notes
Passiflora suberosa ssp. litoralis has the widest geographic range of any
species in supersection Cieca. In the New World, its range extends from
northern México, through Central America, to central Argentina. In these areas it
may be confused with P. pallida and P. obtusifolia, which are sometimes similar
vegetatively. The similarities and differences between these two species are
discussed under their respective descriptions. The primary difference between
P. pallida and P. suberosa ssp. litoralis is the hypanthium diameter, with that of
P. pallida rarely exceeding a width of 4.0 mm and that of P. suberosa ssp.
litoralis commonly 4.0 mm or wider. One of the more useful characters employed
in separating P. obtusifolia and P. suberosa ssp. litoralis is the presence/absence
of inflorescences. When mature, Passiflora obtusifolia bears flowers in long
inflorescences (i.e., 5.3-18.3 cm) and P. suberosa ssp. litoralis almost always
lacks inflorescences; when P. suberosa ssp. litoralis does possess
inflorescences they are not as long (i.e., 2.0-5.0 cm).
There are three major morphological variants of Passiflora suberosa ssp.
litoralis. In México and Central America, P. suberosa ssp. litoralis possess
