Echinocereus triglochidiatus var. arizonicus (Arizona Hedgehog)
This cactus has a very limited distribution and is an Endangered Species. It survives in a narrow elevational zone from the upper Sonoran Desert into the Chapparal (sometimes Madrean Evergreen Woodland) that occurs in its range. Its range covers areas east of Superior, AZ in Gila and Pinal counties.
Here is a selection of photos of individual Echinocereus triglochidiatus var. arizonicus (Arizona Hedgehog) cactus, all taken in the wild.
