Revision as of 17:27, 18 September 2019
Stems usually unbranched (occasionally 2–3-branched), usually pale green, depressed-spheric to ovoid, usually 3.2–11(–18) × 3.8–8(–10) cm, somewhat glaucous; ribs 13–17, tubercles inconspicuous. Spines not obscuring stem, usually only radial; radial spines 7–14 per areole, spreading, straw colored, 6–13 mm, less than 1 mm diam.; central spines 0(–4) per areole (very rarely 1 abaxial central spine per areole hooked, 7–15 mm, brown). Flowers funnelform to campanulate, 1–3.5 × 1–3 cm; outer tepals with purple midstripes and cream or gold (rarely pink) margins, oblanceolate, 10–25 × 5–8 mm; inner tepals yellow to cream (rarely pink), oblanceolate, 15–30 × 5 mm; filaments pale yellow or white; anthers yellow. Fruits indehiscent to irregularly dehiscent, green, becoming tan at maturity, short cylindric, (4–)8–10 × 7–9 mm. Seeds black, 2.5–3 × 3–4 mm; testa cells convex but somewhat flattened apically.
Phenology: Flowering late Apr-early May.
Habitat: Alkaline, clay badlands, mat saltbush communities
Elevation: 1500-1700 m
