Description
editPlants grow in small clumps. Stems are cylindric with 8–13 ribs, measuring 10 cm–40 cm × 5 cm–10 cm (3.9 in–15.7 in × 2.0 in–3.9 in). Areoles are spaced 10–15 mm (0.39–0.59 in) apart. Spines vary, being straight or contorted. Each areole has 1–8 central spines, 15–50 mm (0.59–1.97 in) long, and 7–14 radial spines, 5–25 mm (0.20–0.98 in) long, initially yellowish to brownish but turning gray. Echinocereus arizonicus has deep red to bright orange-red flowers, sometimes with a lighter yellowish-green center,[2][5] 5.5 cm–7 cm × 3.5 cm–5 cm (2.2 in–2.8 in × 1.4 in–2.0 in), with a flower tube of 25–35 mm (0.98–1.38 in) that has short spines and 2 mm (0.079 in) hairs. Fruits are green with a brownish tinge, 20–30 mm (0.79–1.18 in), and have white pulp. The chromosome count is 2n = 22.[6]
Distribution
editPlants are found growing in desert scrub and grasslands of the Chihuahuan Desert in Arizona, New Mexico in the United States and Chihuahua, Mexico at elevations between 1400 and 1900 meters.[7] Plants are found growing along with Quercus turbinella, Quercus emoryi, Arctostaphylos pungens, Cercocarpus montanus, Nolina microcarpa, Dasylirion wheeleri, Agave chrysantha, Muhlenbergia emersleyi, Pinus monophylla, Juniperus pinchotii and Rhus trilobata.[8][9]
