Plants branched forming dense or lax clumps with 20–100 (–500) branches, usually branching before flowering. Stems somewhat lax often sprawling, longest stems sometimes prostrate, cylindric, 8–40 (–100?) × 3.2–15 cm; ribs (6–) 7–10 (–12), crests essentially uninterrupted; areoles (11–) 14–52 mm apart. Spines 6–14 per areole, straight or central spines slightly curved throughout their lengths, ± opaque, white, pale tan, or purplish gray, often extensively tipped or banded with brown; radial spines 5–10 (–13) per areole, 9.5–40 (–47) mm, usually less than 1/2 as long as central spines; central spines 1–4 (–5) per areole, all or mostly projecting, abaxial spine porrect or descending, frequently compressed or angular in cross-section (sometimes sulcate, keeled, or striate), (12–) 20–84 (–96) mm. Flowers (4.5–) 5–7.5 × 5–5.6 (–9) cm; flower tube 10–30 × 10–22 (–40) mm; flower tube hairs 1–2 mm; inner tepals pink or magenta, darkest proximally, 28–55 × 8–14 (–20) mm, tips relatively thin and delicate; anthers yellow; nectar chamber 4–6 mm. Fruits pale yellow-green or dull reddish, 20–30 mm, pulp white or pale-pink. 2n = 22.
