Stem: erect, spherical to cylindrical, 10-20 ribs; 1-4 in (3-10 cm) diameter.
Leaf: spine, red-and-white, red-and-yellow, yellow-and-white, whitish, yellowish, or purplish, tips often darker; radial spines 12-45 per areole, 0.2-0.75 in (4-18 mm) long, central spines absent, or 1-17 per areole, 0.2-1.6 in (5-40 mm) long; spines often held close against the stems (appressed).

Discussion Also known as nylon hedgehog cactus, small-flowered hedgehog cactus, brown-spine hedgehog cactus, hen-and-chickens. The taxonomy of the species is uncertain, with some authors recognizing up to five varieties which are by other authors as separate species. One variety, var. davisii (sometimes called Echinocereus davisii), Davis' green pitaya, is federally listed as an endangered speciesFive varieties are proposed.

Pitaya (pronounced pee-tah-yah) is the phonetic spelling of the original Spanish name Pitahaya, a name given to species of Echinocereus but more broadly applied to a number of cacti that produce sweet, edible fruit.
