Rounded Global Status: G2 - Imperiled
Reasons: Known from area near the Rio Grande in Brewster and southern Terrell counties, Texas and extending south into northeastern and central Coahuila, Mexico. Seven known occurrences in Texas, possibly a few more, with at least a few having good viability and/or located within Big Bend National Park. The total Texas population is estimated at 5,000 - 10,000 individuals. Mexican range is approximately 2.5 times as large as U.S. range. Threatened by collection and development.
Nation: United States
National Status: N2N3

NatureServe Global Conservation Status Factors

Range Extent Comments: It occurs in Texas, near the Rio Grande in Brewster and southern Terrell counties. It extends south into Coahuila, Mexico, occupying a substantial portion of the northern part of the state (Dicht and Lüthy 2005).

Area of Occupancy: 26-2,500 4-km2 grid cells
Area of Occupancy Comments: Assumed 1-5 square km per occurrence.

Number of Occurrences: 6 - 80
Number of Occurrences Comments: At least 7 occurrences in Texas, probably a few more (Benson 1982, Rice 2002). Range in Coahuila, Mexico is approximately 2.5 times as large as U.S. range (Dicht and Lüthy 2005).

Population Size Comments: Plants may possibly be more common than previously thought in Big Bend and Blackgap, with estimate of 5,000-10,000 plants in Brewster and Terrell counties, Texas (Rice 2002).

Number of Occurrences with Good Viability/Integrity: Few (4-12)
Viability/Integrity Comments: At least 3-4 viable occurrences in TX with several others unranked.

Overall Threat Impact: Medium
Overall Threat Impact Comments: Being collected in great quantities by commercial dealers for direct sale from the field. Also threatened by further development which could modify habitat and make populations more readily accessible to collectors.
