are greatly elongated (16.88-32.00 mm long and ca. 7.5 times longer than they
are wide)(#5, 3; #6, 2) and much longer than the outer coronal filaments
(quotient, i.e., length of filaments in the outer row/sepal length, commonly
ranging from 0.09-0.21)(#9, 3), outer coronal filaments that are connate (#55, 1)
and adnate to the sepals (#51, 1), pollen that is presented laterally (#63, 1), a
sulcate floral nectary floor (#71, 1), and a limen that is not recurved but inclined
toward the operculum (#73, 1). Passiflora viridiflora also possesses fruits that
are widely ovoid with a conical tip (#76, 4). Passiflora megacoriacea is distinctive
based upon its wide hypanthium (commonly 8.9-12.5 mm)(#4, 0/1) and limen
floor (commonly 5.0-7.0 mm)(#23, 2), elongated androgynophore (commonly 7.3-
8.0 mm long)(#18, 0), staminal filaments that are generally less than half the
length of the androgynophore (#19, 2), 30 to 40 outer coronal filaments (#7, 2)
that are between 7.7 and 10.3 mm in length (#8, 1) and somewhat dilated toward
the apex (#54, 1), floral nectary with a raised annulus (#70, 1), petiolar nectaries
that are most commonly on the upper half of the petiole (#36, 1), and seeds that
are about 5.0 mm long (#26, 0) and 3.0 mm wide (#27, 1).
The clade containing most of the species that have, in the past, been
separated out of P. coriacea possess the following synapomorphies:
transversely elliptic leaves (#85, 2) with short central leaf veins as compared to
the leaf widths (quotient, i.e., central vein length/leaf width, commonly ranging
from 0.19-0.44)(#32, 2), very shallow leaf lobes (quotient, i.e., distance from the
leaf outline to the sinus margin/distance from the leaf outline to the leaf base,
commonly ranging from 0.02-0.20)(#34, 1), and lateral veins that are much
