When this species was first found in 1988, it used to be under great pressure from illegal collection. An estimated population reduction of 80% in a ten year period was inferred. However, it is now available in the market from propagation and this has reduced the pressure on wild populations. Furthermore, other subpopulations have since been found. Nonetheless, a past reduction in the population of around 30% (generation length five years) due to illegal collection is estimated. Even though the species has a very restricted range (extent of occurrence =160 km2, one location) it is listed as Vulnerable because there is no continuing decline of the population.

Population [top]

Population:The species is known to occur in four localities (W.A. Fitz-Maurice pers. com. 2010). One of the subpopulations was severely depleted by collectors (Pilbeam 1999).
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:No
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in high mountains, in Quercus forests on steep slopes and grows in leaf-litter and sometimes on inaccesable cliffs (Pilbeam 1999).
Generation Length (years):5

Use and Trade [top]

Use and Trade: The species is used as an ornamental, and it has been found in Mexican trade (Bárcenas).

Threats [top]

Major Threat(s): In the past illegal collection was a major threat (Pilbeam 1999), however, today this species is widely available from propagation and the pressure in wild populations is minimum.

Conservation Actions [top]

Conservation Actions: The species is listed in NOM-059-SEMARNAT-2010 under "Special protection" (Pr; Protección especial; SEMARNAT 2010).

Amended [top]

Amended reason: The species distribution map has been added.
