We have a name!

"Passion" does not refer to love, but to the Christian theological icon of
the passion of Christ
on the cross. In the 15th and 16th centuries, Spanish Christian missionaries
discovered this flower and adopted its unique physical structures, particularly
the numbers of its various parts, as symbols of the last days of Jesus Christ and especially
the Crucifixion. For example:
the radial filaments which can number more than a hundred and vary from flower
to flower were taken to represent the Crown of Thorns. The ten petals and sepals
can represent the ten faithful apostles. The top 3 stigmata
can represent the 3 nails and the lower 5 anthers the 5 wounds. The flower has
been given names related to this symbolism throughout Europe since that time. In Spain, it is known
as Espina de Cristo (Christ's Thorn). In Germany it was once known as
Muttergottes-Schuzchen (Mother-of-God's Star). Popular culture being what it is,
however, passionflowers and especially passionfruit are frequently
used with sexual or romantic innuendo, giving rise to such
uses as a one-time soft drink named Purple Passion.
In Israel they are referred to as
clock-flower (שעונית). In Japan, they are known as clock
plant (時計草, tokeisō?).
In North America
they are also called the Maypop, the water lemon, and the wild apricot (after
its fruit). Native
Americans in the Tennessee area called it
ocoee, and the Ocoee River and valley are
named after it. In Hawaiian, they are called lillikoi.

Thank you to Melody for giving me the link to the Wikipedia entry. Amazing that this little flower can represent something so incredible. And just to be clear~ The above explaination of the flower is copied from the Wikipedia page that is shown in Melody's comments under the Unusual Flower post. And thanks to everyone else who chimed in to tell me the name of it!
