Description:— Shrub to small tree, 1–6(–10) m, forming a trunk to 33 cm diam., main shoots erect to arching, stout. Areoles rounded, cushion-like, initially 3–6(–8) mm diam., later to 20 mm diam., producing straight spines, and 1–4 brachyblast leaves. Spines 0–6 on twigs, fasciculate to spreading, 2–5 cm, increasing in number and size on older branches. Leaves elliptic or obovate, often narrowly obovate on main shoots, flat or folded upward and recurved, (4–)5–12 × 2–7 cm, petiole short to indistinct, base of lamina attenuate, apex rounded to broadly acute, lateral veins (3–)4–7(–8). Inflorescence terminal, cymose-paniculate, by proliferation from the receptacles, 2–12-flowered, dense to lax, or flowers sometimes solitary. Flower perigynous, 4–7 cm diam., rose-like, showy; pedicel 1 cm, stout; receptacle turbinate, with prominent podaria and 3–8 areoles mainly on the upper half; bracts sepal-like, fleshy, outer bracts 4–6, spreading, inner bracts 4–6, erect, green with purplish to nearly black margin, keeled; outer perianth-segments 2–5, asymmetric, greenish red to reddish purple, inner segments 7–10, 20– 30 mm, emarginate, deep magenta-pink; stamens 5–10 mm, loosely clustered around the style, filaments white; ovary half-inferior to inferior, with distinct septal ridges at the roof; style 7–15 mm, cylindric, stigma-lobes 5–10, suberect.
