Tobusch fishhook cactus flowers
One subspecies of this cactus is the Tobusch fishhook cactus (Sclerocactus brevihamatus ssp. tobuschii), a federally listed endangered species. It is often treated as a species in its own right called Ancistrocactus tobuschii. This rare plant is known from about 200[1] to about 500[2] individual specimens on the eastern part of the Edwards Plateau. It occurs in the Juniperus ashei-Quercus fusiformis plant association on calcareous soils.[3] Threats to the species include collecting and development in its habitat.[2]
