Cereus peruvianus f. monster crested (Monstrous)

It is a cactus of a peculiar monstrous and crested shape, which makes it very appreciated and sought after by cactus collectors. Its green epidermis has white downy areoles, which are formed very close to each other on the crest, almost forming a continuous line, which are, however, sparser along its stem. At the apex it has small needle-like spines of a red-brown color.
