It was found in the Mexican states of San Luis, Coahuila and Nuevo León. This species differs so significantly from the planet that its first appearance indicates that there is no close relationship between them. It is a larger plant, spherical, tending to be short columnar, reaching a maximum of 25 to 30 cm or higher. It has sharp edges, usually eight, and has long, well-spaced wart spots. The flexible, curved spines resemble the horns of an African horned antelope. These plants vary greatly in length, color (from black, brown or near yellow to milky white), and the degree of curl of the spines, and can almost cover the plant body with a tangle. The number of white spots endemic to the genus is also very variable, but some plants are almost spotless, while others are covered with dense spots. The bright and shiny yellow flowers can reach up to 7 cm long and the flower heart is red. As mentioned earlier, the species is very variable, and differences in morphology and spots have led to the emergence of a large number of named varieties.
In terms of cultivation, it is the slowest growing of plants in the genus, but it remains to be seen. In this regard, its first few years gave the impression that it could grow taller than the big boys, but soon the fast growth slowed down, because after about 5 years, it slowed down and could only produce a plant the size of an apple at most. It is even less likely than other species to reach any size without brown or black spots on the body, which seem to be more susceptible. This can be caused by keeping the plant at too low a temperature, or lack of nutrients or potted plants.
Of course, this kind of large, spotless Rui Feng Jade is rare on the stand. It is recommended to use an open potted mixture with up to 50% sand content, adding limestone or replacing grit with limestone, as limestone is often contained in the wild environment in which it is grown.
