Trees or shrubs, sparsely to densely branched, 1–2(–4) m. Stem segments firmly attached, cylindric, 10–30(–50) × 2–2.5(–3) cm; tubercles prominent, narrow to broad, 1.5–4.5 cm; areoles elliptic to subcircular, 4–5.5 × 4–5 mm; wool white or yellowish to tan, aging gray-black. Spines 6–20(–30+) per areole, often accompanied by 0–5 short bristlelike spines at areole margins, usually in distal areoles; major abaxial spines deflexed to divergent, subterete to flattened; major adaxial spines ascending-divergent, terete, yellow or tan to deep red-brown, aging gray, the central spine longest, 12–30(–38) mm; sheaths white to grayish with yellow to golden tips, baggy to tight fitting. Glochids in inconspicuous to small adaxial tuft, yellow to brown, 0.5–2 mm. Flowers: inner tepals bright yellow to bronze to brick red, spatulate, 20–30 mm, apiculate-emarginate; filaments red; anthers yellow; style and stigma lobes white to light green. Fruits tan at maturity, obconic to ellipsoid, 15–35 × 15–20 mm, dry, tuberculate, densely to sparsely spiny (rarely spineless), with apical flange above shallow umbilicus; basal tubercles longest; areoles 12–30. Seeds pale yellow to tan, angular or squarish in outline, warped, 3.5–5 × 3–4.5 mm, sides smooth, each with 2–4 large depressions; girdle smooth.
Distribution
Ariz., Calif., Nev., Utah, n Mexico.
Discussion
Varieties 4 (4 in the flora).
Cylindropuntia acanthocarpa hybridizes with C. abyssi, C. echinocarpa (= C. ×deserta), C. bigelovii (= C. ×campii), C. leptocaulis (see C. ×tetracantha), C. ×multigeniculata, C. spinosior, C. versicolor, and C. whipplei (= C. congesta). Hybrids of C. acanthocarpa and C. ×multigeniculata are more open in habit, with longer stem segments than C. ×multigeniculata and with reddish filaments like C. acanthocarpa.
Selected References
None.
