Stems 4–34.5 4–10 cm; ribs 18–21; areoles 8–19 mm apart along ribs; areolar glands present at least seasonally. Spines 13–19 per areole, purplish pink to purple or nearly white with brown tips; radial spines 12–18 per areole; abaxial (shortest) radial spine 6–20 × 0.3–0.6 mm; adaxial and lateral (longest) radial spines 9–37 mm; central spines 1–3(–4) per areole (usually absent from sexually immature plants), erect to ascending, 12–44 × 0.5–0.8 mm; longest adaxial central spine straight to curved upward, abaxial central spine 13–35 mm (absent in var. erectocentrus). Flowers 3.6–6 × 4–9 cm; inner tepals whitish to bright rose-pink or lavender, basal portions olive-green to orangish brown, chestnut or maroon, (2–)2.5–4.3 × 0.6–1.8 cm; stigma lobes red to brownish red, papillae red or green. Fruits dehiscent by vertical slits, ellipsoid-cylindric, 12–20 × 5–8+ mm. 2n = 22.
Distribution
Ariz., Mexico.
Discussion
Varieties 2 (2 in the flora).
The populations of Echinomastus erectocentrus north of Tucson, Arizona, are geographically, ecologically, and morphologically intermediate between the two named varieties. Echinomastus erectocentrus is replaced to the northwest by E. johnsonii; the two species are only weakly differentiated.
Selected References
None.
