More Night Blooming Cactus

It seems that the columnar cactus are the ones that most commonly have night blooms. They are generally large and light colored. This is likely because of the night pollinators, such as bats. They make an easy to see and echo-locate target. I also note that the flowers seem to grow from almost random spots on the cactus plant's stems. We have one these growing right by our house at a neighbor's side yard, so I know approximately when they are blooming elsewhere and can go look for the blossoms early in the morning.
