Range Description

There are currently two disjunct subpopulations of this species. The small subpopulation in Querétaro occurs on medium to steep slopes of volcanic rock near Mesa de Léon in a very small area (extent of occurrence is 25 km² and the area of occupancy is less than 10 km²). A new subpopulation has recently been discovered in Zacatecas (not shown on the species' range map to protect it), which is much larger. It grows at altitudes between 1,400 and 1,900 m asl.
