Habitat and Ecology [top]

Habitat and Ecology:

The species grows on novaculite outcrops in full sun among sparse Chihuahuan desert scrub, usually in cracks or chips of novaculite or in mats of Selaginella. It grows associated with other rare species. It flowers between March and June, fruit are produced a month after flowering (Poole et al. 2007).


Use and Trade [top]

Use and Trade: The species is locally collected and used as an ornamental, but this is a threat only for one subspecies.

Threats [top]

Major Threat(s): Illegal collection is a threat for one subpopulation found by a roadside.

Conservation Actions [top]

Conservation Actions: The state of Texas protects Nellie’s cory cactus (Escobaria minima), which is one of six federally threatened or endangered cactus species that occur in the Chihuahuan Desert of Texas. The Texas Parks and Wildlife Department monitors the status of Escobaria minima in the Big Bend area of West Texas (Robbins 2003). It is listed in CITES Appendix I.

The species occurs inside private lands to which nobody has access. A population study would be desirable if access to the population were available.
