Hylocereus undatus, night blooming cereus. This well-known Punahou hedge cactus has many perianth segments and stamens. Note also the several pale yellow stigmas visible in the lower front part of the flower. The sectional view shows numerous parietal ovules in the single locule of the inferior ovary.
