Spineless Hedgehog Cactus (Echinocereus triglochidiatus var. inermisi)
Family: Cactaceae (Cactus Family)
Description: a spineless or nearly spineless variant of the more common claret cup cactus. 3-6 inch stems clustered in spherical clumps or mounds. 8-10 ribs run vertically along each stem. Scarlet flowers appear on stem tips in May.
Range: occurs in Colorado and Utah. Look for it growing in Colorado National Monument in Ute Canyon and No Thoroughfare Canyon on Kayenta rock.
Did you know: although this cactus's name suggests that it is "spineless," some individuals contain spines on all or part of the stem. Spinelessness is thought to be related to soil conditions.
