Revision of Passiflora Subgenus Decaloba ... - Passion Flowers

111
mm long (#13, 1), and 0-2 floral bracts (#42, 1). The absence of petals is the
only nonhomoplasious character supporting the monophyly of the supersection.
Within supersection Cieca, Passiflora clypeophylla, P. juliana, P. viridiflora, P.
megacoriacea, P. mcvaughiana, P. xiikzodz, P. itzensis, P. sexocellata, P.
coriacea, P. tacana, and P. obtusifolia form a clade. Within this group, P. juliana,
P. viridiflora, and P. megacoriacea constitute a clade, with Passiflora juliana and
P. viridiflora being most closely related. A clade consisting of P. mcvaughiana,
P. xiikzodz, P. itzensis, P. tacana, P. sexocellata, and P. coriacea is also evident,
with P. xiikzodz and P. itzensis present as sister species. The two Guatemalan
endemics, P. trinifolia and P. eglandulosa, form a clade. A clade consisting of P.
tridactylites, P. lancifolia, and P. macfadyenii is also present, with P. lancifolia
and P. macfadyenii sister to each other. Passiflora tenuiloba, P. pallida, and P.
suberosa ssp. litoralis form a clade, with P. tenuiloba and P. pallida being most
closely related. Finally, Passiflora suberosa ssp. suberosa is cladistically basal
within the supersection.
Passiflora suberosa ssp. suberosa is defined by the presence of white sepals
(#49, 1), filaments in the inner coronal row that are reddish purple at the base
with a yellow capitate head (#56, 2), whitish pollen (#64, 1), a sulcate floral
nectary floor (#71, 1), ovoid fruits (#76, 3) and three-lobed leaves (rarely unlobed
or bilobed)(#84, 4). The remaining members of the supersection form a clade
based upon a shift from plants that commonly possess four or more laminar
nectaries to those that possess none (#37, 2)(with shifts to leaves with less than
four and more than four laminar nectaries occurring in many taxa) and ellipsoid
