Cacti of West and Southwest USA - Sclerocactus


Plants > Cacti > Sclerocactus
Sclerocactus cacti resemble the echinocereus species but are usually single and have central spines that are hooked rather than straight, hence their common name of fishhook cactus. Spines grow from tubercles arranged in prominent ribs. Over a dozen different types have been identified, found in higher elevation desert regions, places not generally associated with cacti, hence the plants are not often spotted. Many species are quite rare and localized.


There are 12 other US species:

Sclerocactus brevispinus, Pariette cactus, northeast Utah - Uinta Basin area (rare)
