Shrubs, ascending, with strict branches, 0.5-1.5 m. Stem segments firmly attached, green, (5-)10-26 × (1.7-)2.5-4.5 cm; tubercles prominent, narrowly elliptic to oval, often subribbed, (0.9-)1.3-2.6 cm; areoles elliptic to obdeltate, 4-7 × 2.5-5 mm; wool yellowish tan, aging gray. Spines 11-18(-28) per areole, at most areoles, moderately to wholly obscuring stems, spreading or erect, whitish, pale yellow to pinkish tan to reddish, aging brown or black, terete or abaxial spines basally flattened, grading in length, the longest porrect to reflexed, 2-2.5(-3.5) cm, with 0-6 bristlelike spines at areole margins; sheaths slightly baggy, whitish becoming yellow to golden apically. Glochids in thin adaxial crescent, yellow or tan to rusty, 0.5-6 mm. Flowers: inner tepals greenish yellow, often with tips reddish abaxially, spatulate, 22-30 mm, apiculate to emarginate-apiculate; filaments yellow-green to green; anthers yellow to orange-yellow; style cream to yellow, sometimes basally greenish; stigma lobes greenish cream, cream or yellow. Fruits yellowish, drying tan, globose, tuberculate, budlike with spines similar to those of stem segments but slightly shorter, often reflexed; proximal tubercles slightly elongated if fruits fertile; umbilicus 4-5 mm deep; areoles 22-32(-40). Seeds pale yellow, angular-suborbicular, flattened to slightly warped, 4.5-6 × 4.5-5.7 mm, sides with 3-5 depressions; girdle smooth, not protruding. 2n = 22. Flowering spring (Mar-May). Desert alluvial flats, bajadas, sandy, gravelly to rocky substrates; 100-1000 m; Calif.; Mexico (Baja California).
