This is epiphyllum anguliger, or Fishbone Cactus, that bloomed last week. The flowers were the size of a cup and saucer with a scent that was mild, but heavenly...sort of jasmine/fruity/citrus. Delicious. This flower (to me) smells more like some plumeria products I've bought than actual plumeria does.
