Listing Status:   

Where Listed: WHEREVER FOUND

General Information

A small (1-1.5 cm above ground) unbranched cactus, usually not more than 4 cm wide. Has "cottony" areoles and bright white radial spines. Central spines usually lacking, but each areole may have 1-3 slender spines. Most of the stem remains underground all year, during dry periods the portion of the plant exposed may shrink and become flush with the ground surface.

Habitat Requirements

Found only on one type of high-calcium limestone outcrop in the Mexican Highland vegetation community at elevations of 1,280-1,433 meters (4,200 feet). Soils are thin with a soil crust of lichens, mosses, and algae, and bedrock is very near the surface at occupied sites. Plants tend to be in the open, not underneath other plants. Overall vegetation at occupied sites is sparse.

Movement / Home Range

Known range is very small and limited. Individuals are not distributed across all potential habitat, so there are likely microsite factors also controlling distribution. Insect predation (moths and beetles) is a significant cause of mortality to adult plants.

Reproductive Strategy

Flowering begins in mid-March extending to mid-April. Flowers are pale yellow to parchment in color, and 10-18.5 mm in length. Fruits are spheroid to ovoid, initially orange-red to scarlet but turn brownish when dry. Each fruit has approximately 20 seeds. Seedling mortality is high, with rainfall an important factor. Plants achieve sexual maturity at 17-28 mm in diameter. The number of flowers produced increases with the age and size of the plant and are also positively correlated with rainfall.

Other

Very vulnerable to ground disturbing activities that can damage or kill individual cacti. The thin soils may be disturbed by vehicle use, livestock trampling, or humans hiking across the landscape. The normally sparse native vegetation provides some protection from wildfire; however, invasive non-native plants that establish and increase overall plant density increase the risk of damaging fires in the habitat. Losses of adults to drought or predation restricts the ability of a local population to survive over time.
