We originally had this as Lepismium cruciforme until a customer corrected us. This primitive cactus, from eastern Brazil, can be epiphytic or grown in soil. It has highly variable stem segments but generally they are 3-4 angled and light green, turning reddish purple in higher light or stress. The flowers are relatively small and light yellow, and the fruits are little red berries. These plants are rooted cuttings in 4-inch pots.
