Classified as Vulnerable based on known decline in habitat over the past 50 years (ca. two generations) of 30-50%. In some places populations have declined by as much as 90% due to land clearing, but overall decline appears to be between 30% and 50%.

|Population:||This species is known from six localities. Demographic studies at one of the localities in Coacoazintla (Veracruz state) indicate that the local population may exceed 500,000 individuals.|
|Habitat and Ecology:||Plants are widely distributed from low to moderate elevations and are found in areas ranging from evergreen tropical forests to cloud forests and mixed deciduous woodlands and a range of geological substrates. Typically found in rocky hills.|
|Major Threat(s):||The mountain cloud forest habitat is threatened by habitat destruction. Forest is cleared for agriculture and cattle farming and is also impacted by the removal of wood for charcoal production. Strip mining to remove basaltic rock (e.g. in CoaCoatzincla) is also a threat, resulting in the removal of forest.|
|Conservation Actions:||This species is listed on Appendix I of the CITES Appendices. Plants are conserved in the Sierra Gorda Biosphere Reserve in Queretaro state.|
