Justification:
Two locations were lost in the last few years due to agriculture, construction, deforestation and resulting erosion. The only location left (about 9 km² in extent) is threatened by erosion due to over-pasturing and deforestation. There are about 3,000 mature individuals remaining. No seedlings or young plants detected. Generation length is 10 years.

Habitat and Ecology [top]

Habitat and Ecology: Grows in clusters hidden in the grass on lava soils. The habitat is now an induced grassland as a result of the felling of the Quercus woodland which previously dominated the area. The habitat is locally classified as pastizal inducido (Induced Grassland) (Rzedowski 1978).
Systems: Terrestrial

Threats [top]

Major Threat(s): Erosion, deforestation and over-pasturing. Illegal collection is also a problem.
