Description
This is a very slow growing plant with an external layer of epidermal cell of Ortegocactus macdougalliiSN|3389]]SN|3389]] that cover a second inner layer of tissues of Opuntia humifusa like a glove. The plant colour is the unmistakable grey-blue metallic tone of the Ortegocactus, but the plant shape is that of a minuscule Opuntia with small irregular cladodes up to 3-5 cm of length. This plant is quite unstable and have a tendency to revert to common Opuntia shoots.
Note
A graft-chimaeras can be given their own genus name (which is a combination of the two constituent generic names) preceded by a + sign. + Ortegopuntia derives from the combination of Ortegocactus and Opuntia.
