Shrubs, forming low clumps or with trailing branches, 10–30 cm. Stem segments not disarticulating, green to blue-green, flattened, elliptic to obovate, 6–15 × 5–12 cm, low tuberculate, papillate; areoles 7–11 per diagonal row across midstem segment, subcircular to elliptic, 3–5 × 2–4 mm; wool tan. Spines absent or only l spine in 1–few distal areoles, deflexed, yellow to gray, straight, terete, to 10 mm. Glochids in dense crescent at adaxial margin of areole and dense subapical tuft, yellow, to 6 mm.
