Cereus forbesii, from Bolivia and Argentina, recently has been lumped into Cereus validus, but the description does not remotely match these plants. For one thing, the typical species is a columnar cactus with 4-sided stems. The flowers are the typical Cereus form, large and white with purple hues. The plants are tightly spiraling. These plants are rooted cuttings in one-gallon pots.
