Likely one of the night blooming epiphytic Cereus. Most are white
flowered, and most have very large flowers.
The genera are:
Hylocereus (called the night blooming cereus)
Selenicereus (called the Queen of the night)
Harrisia (called moonflowers, and jungle apples)
Among these genera are many species with the flowers you describe. I'm
sending you a photo of a Hylocereus bloom, in a seperate email. Most of
these plants have similar flowers.
Hope I helped.
