Quintana Roo, México; and J. Tillich 3558, in Black River, Mauritius) has ovate
leaves that may be unlobed, bilobed or trilobed on the same plant. When
unlobed, the leaves are commonly greater than 2.0 cm wide. When lobed, the
leaves are usually shallowly lobed 0.20-0.41 the distance to the base, the lateral
and central lobes are greater than 1.0 cm wide, and the angle between the lateral
lobes is 45-100º. Another less common variant of P. pallida (as exemplified by J.
K. Small & C. Mosier 5511, in Cox Hammock, Miami-Dade Co., Florida, USA;
and J. Small & J. Carter 194, between Perrine and Long Prairie, Miami-Dade
Co., Florida, USA), has narrowly ovate leaves that may be unlobed, bilobed or
trilobed on the same plant. When unlobed, the leaves are commonly less than
1.0 cm wide. When lobed, the leaves are usually deeply lobed 0.82-0.90 the
distance to the base, the lateral and central lobes are commonly less than 0.7 cm
wide, and the angle between the lateral lobes is greater than 100º. However, all
the specimens brought together here as P. pallida are all relatively small in
stature in their native habitats in the New World, possess similar small flowers
with short coronal filaments and occur in a similar range of elevations.
MacDougal has reported the appearance of an occasional, well-formed but
small petal in other species within supersection Cieca (MacDougal, 1992). I
have also seen this in P. pallida in several of my greenhouse accessions and in
the field in Quintana Roo, México.
Passiflora pallida appears to be largely self-compatible and autogamous in
cultivation. Artificial self-pollinations of a clone of the species from Tamaulipas,
México (MacDougal 259) by John MacDougal proved successful. Passiflora
