--><span class="statement" id="st-undefined" data-properties=""><b>Trees,</b> densely branched, with older branches at base of crown dark brown, clinging to usually solitary trunk, 0.3–1.5(–3) m. <b>Stem</b> segments whorled or subwhorled, green to gray-green, 4–13(–18) × (2–)4–5.5 cm, distal ones usually very easily detached (propagules); tubercles salient, broadly oval, 0.4–0.8 cm; areoles elliptic-deltate, 5–6 ×3–4 mm; wool white-yellow to brownish, aging gray. <b>Spines</b> (8–)10–15 per areole, at most areoles, interlaced with spines of adjacent areoles, usually uniformly, diffusely spreading and nearly completely obscuring stem, pale yellow to yellow to tan, aging brown; abaxial spines spreading to deflexed, subterete to flattened, the longest (10–)15–25 mm; adaxial spines erect or spreading, terete, the longest (10–)20–28 mm; sheaths uniformly whitish or pale yellow, not obviously baggy. <b>Glochids</b> in broad adaxial crescent, sometimes extending along areole margins, yellow, 3–4 mm. <b>Flowers</b>: inner tepals pale green to whitish, sometimes tipped red, spatulate, (15–)20–25 mm, emarginate-apiculate, often erose; filaments green; anthers orange; style light green; stigma lobes light to dark green. <b>Fruits</b> usually sterile, not proliferating, yellow at maturity, cylindric to broadly obconic, (15–)22–40 × (8–)16–20(–28) mm, fleshy-leathery, strongly tuberculate, becoming spineless, losing bristlelike spines of young fruit; umbilicus 8–10 mm deep; areoles 36–64, evenly spaced. <b>Seeds</b>, when present, pale yellow, in gelatinous mass, angular to squarish in outline, 2.5–4 × 2.2–3.5 mm, warped, sides with 1–2 large depressions; girdle smooth or as very narrow marginal ridge. <b>2n</b> = 22 or, usually, 33.</span><!--

|discussion=<p><i>Cylindropuntia bigelovii</i> forms two hybrids. <i>Cylindropuntia</i> ×fosbergii (C. B. Wolf) Rebman, M. A. Baker & Pinkava (= <i>C. bigelovii</i> × <i>C. echinocarpa</i>), which L. D. Benson (1982) treated as <i>Opuntia</i> bigelovii <i></i>var.<i> hoffmannii</i> Fosberg, occurs southwest of the Salton Sea, California, forms shrubby trees 1–2 m with yellow-green inner tepals and green filaments, and has a chromosome number of 2n = 33. <i>Cylindropuntia</i> ×campii (M. A. Baker & Pinkava) M. A. Baker & Pinkava (= <i>C. bigelovii</i> × <i>C. acanthocarpa</i>) forms more open trees than O. bigelovii, has yellow-green inner tepals and filaments, and has a chromosome number of 2n = 44.</p>
