- Bunched cory cactus is a rounded cactus, usually with single stems to 4 inches tall.
- Life History
- The bunched cory cactus blooms from July through September, sometimes as late as October and as early as April, depending on rainfall. Its fruit matures from late August-November. This rare cactus is known from about 25 sites, many within Big Bend National Park in southern Brewster County. Growing within Big Bend National Park and on large private ranches, this cactus is fairly well protected from cactus collectors due to the remoteness of its habitat. However several sites within Big Bend National Park are well known, and even though these sites are monitored, a few individuals of bunched cory cactus still fall prey to cactus poachers.
- Habitat for bunched cory cactus includes slopes, ledges, and flats on sparsely vegetated limestone rock outcrops (most commonly of the Boquillas or Santa Elena Formations) in the lechuguilla shrublands of the Chihuahuan Desert.
- This species occurs in one of the most remote and inaccessible areas of the state, the arid lands surrounding the Lower Canyons of the Rio Grande River. Global range includes Brewster and Terrell counties in Texas, and the state of Coahuila in Mexico.
