Echinocereus triglochidiatus

A common clumping cactus. Unlike Echinocereus coccineus, this species is diploid and the flowers have both functional stamens and a functional pistil. The two also differ in distribution and spine characteristics. E. triglochidiatus has flattened or angular spines, while those of E. coccineus are terete.

Plant habit south of Emory Pass in the Black Range, 4 Jun 2006. My identification of plants from this site is somewhat tentative; it is possible these are E. coccineus.
