Trees or treelike shrubs, with trunk(s) and main branches spreading, bearing terminal tufts of usually drooping branchlets, 2-4 m. Stem segments easily detached, gray-green, 4-16 × 1.2-2.5 cm; tubercles prominent, narrowly oval, 1-2 cm; areoles subcircular to obdeltate, 5-7 × 3-4.5 mm; wool tawny to yellow-brown, aging gray. Spines (7-)9-14 per areole, at most areoles, erect or spreading, yellow, aging red-to gray-black with pale tips, terete or abaxial ones slightly flattened, the longest to 3 cm; marginal bristlelike spines shorter, 0-4; sheaths pale yellow becoming golden apically, baggy. Glochids in adaxial crescent and sometimes small tuft, yellow, inconspicuous, 0.5-2 mm. Flowers: inner tepals pale reddish maroon-brown, elliptic, of irregular lengths, 8-15 mm, emarginate-apiculate; filaments green; anthers yellow; style and stigma lobes cream. Fruits easily detached, tan when mature and fertile, globose, 17-24 × 17-21 mm, dry, tuberculate, spineless but bearing numerous very long glochids; basal tubercles not markedly longer than distal ones (except in sterile fruits); areoles 30-40. Seeds pale yellow, rounded-deltoid, slightly flattened, 3-4.5 × 3-4 mm, sides smooth; girdle smooth, not protruding. 2n = 22, 33.
