| What leads me away from thinking it's a night-blooming cereus is that on Mercedesladie's plant each petiole has a single leaf, and there are no branching petioles or lobed leaves. On my cereus, the leaves come off the petiole, or stem, at an angle, not straight as in her picture, and the stem itself angles at that point and heads off to where another leaf will sprout. The image from TopTropicals has lobed or at least curly-edged leaves; the Google picture shows stems extending beyond the junction with the leaf. I suspect they are different hybrids, so they don't quite look like each other, but neither one, to my eye, looks enough like Mercedesladie's picture to make me think her plant is an Epiphyllum. By my standards the room is only sort of messy. -- Bill |
