Yet another buggered-up genus in the Cactaceae, this is supposed to be in Selenicereus. Might as well be in Euphorbia as much as it resembles other species in Selenicereus, so we'll leave it in Cryptocereus. From Chiapas in southern Mexico, this species has flattened light-green stems with alternating, rounded lobes. The flowers are white, but the purplish tepals make them somewhat secondary. These plants are rooted cuttings in 5-inch pots.
