As far as is known, this species has a very small extent of occurrence, certainly less than 100 km² and its area of occupancy may only be a few square kilometres. The species is very attractive and is highly sought after by collectors, although part of the population grows in inaccessible areas. Given its small range, the threat of collection, and that it is known from a single location, it is listed as Critically Endangered. If the population in the future is found to be more extensive and not as threatened, a lower category of threat may be warranted.
|Range Description:||This species is endemic to Mexico, and is found only in the southeastern part of the state of Coahuila on the Sierra Madre Oriental at elevations of around 2,000 m asl. The species is known only from two collections from the same location (Taylor 1985; note Taylor treats this incorrectly as two localities).|

|Population:||There is no information available on the population size, but it appears not to be common.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:|
The species grows in harsh mountain habitats in grassland with limestone rocks, exposed to sun and wind (Taylor 1985). It forms hemispherical mounds with many stems.
|Continuing decline in area, extent and/or quality of habitat:||No|
|Use and Trade:||The species is sought after by collectors.|
|Major Threat(s):||Illegal collection is the main threat to the species, however, much of the area is inaccessible.|
The species does not occur in any protected areas. It is legally protected in Mexico by the NOM-059-SEMARNAT-2010, where it is listed under category "subject to special protection" (Pr; SEMARNAT 2010). The species was previously listed by Anderson et al. (1994) as Susceptible.
