It is a cactus called "chimera", which in mythology is an animal made up of the parts of the body of different animals. In botany the term ''chimera'' means that one plant have the characteristics of two different species. In this case, as the name suggests, we have a spectacular cross between the genus Stenocereus and Obregonia denegrii. We are therefore obviously talking about a grafted plant, because it is not present in nature: a very rare and particular plant, which combines the properties of two families together to create a unique and unmistakable genus!
