Taxon: Escobaria minima
Common Names: Nellie's Cory Cactus, Dwarf Cory Cactus, Least Cory Cactus, Birdfoot Cactus
Status: Endangered, listed in 1979. It was once widely distributed in Texas but was over-collected. This species is now known only from three sites, all in Brewster County, according the Texas Parks and Wildlife Department.
The TPWD describes this species thus: "This tiny cactus with its thick whitish spines and attractive pink flowers (larger than the plant itself) is highly prized among collectors. It blooms primarily in May, but the blooming period lasts from March - June. Afterwards, it produces fruit that ripens from June - October. Nellie's cory cactus was once found on highway right- of-ways, but was extirpated due to intense collecting pressure."
