Shrubs or trees, with short trunk, many branched, 0.5–1.5 m. Stem segments not disarticulating, grayish green, flattened, reniform, circular, elliptic, or obovate, (7.5–)10–18(–25) × 5–25 cm, low tuberculate, pubescent; areoles 8–13 per diagonal row across midstem segment, circular, 3–3.2 mm diam.; wool white to tan, aging gray. Spines absent. Glochids numerous, nearly filling areole, red-brown to white, 1–2.5 mm. Flowers: inner tepals yellow throughout, aging apricot to orange, obovate-apiculate, 25–38 mm; filaments whitish; anthers yellow; style green; stigma lobes dark green. Fruits red with green flesh, obovate, 20–35 × 15–23 mm, fleshy, short pubescent, spineless; umbilicus 5–7 mm deep; areoles (30–)36–52. Seeds yellowish, elliptic to subcircular, angular, 3–3.5 × 2.5–2.8 mm, thick, sides smooth or with 1–2 depressions; girdle protruding about 0.3 mm. 2n = 22.
Phenology: Flowering spring (Mar–Apr).
Habitat: Calcareous to volcanic flats, hillsides, sandy to gravelly desert soils
Elevation: 600-1300 m
Distribution
Tex., Mexico (Chihuahua, Coahuila, Durango).
