1992). I also noticed this in the same clone (MacDougal 4633) and in another
clone given to me by T. Skimina (Skimina 131). Tim Skimina (pers. com.)
successfully crossed MacDougal 4633 and Skimina 131. The fruits from this
cross were greenish yellow with white spots and possessed 30-40 light brown
seeds. After approximately 35-40 days, the mature fruits began to soften at the
base and, at that time, became very attractive to animals in and around his
garden. It is due to Tim Skimina’s efforts that we now have such detailed
information about the fruits of this species.
Passiflora itzensis is likely self-incompatible. Artificial self-pollinations of
several clones of this species were carried out by MacDougal but proved
unsuccessful, and no fruits were produced by autogamy in two years of
cultivation (MacDougal, 1992). In the four years that I have grown P. itzensis at
the University of Florida, no fruits have been produced by autogamy. However,
T. Skimina (pers. com.) was able to cross P. itzensis with P. obtusifolia.
