Field Notes
Description:
Single or clustered cylindrical stems grow to about 6 inches (15 cm) tall. The plant body is nearly concealed by dense, white, straight radial spines, in contrast to 1 to 3 central spines per areole, one of which is dark-colored and hooked. Crowns of bright pink flowers almost an inch (25 mm) across are borne just below the stem tips in early summer. The bright red, slightly fleshy fruits are presumably eaten by birds.
Habitat:
Arizona south of the Mogollon Rim south into Sonora in desert and woodland habitats.
