|discussion=<p>Cylindropuntia spinosior forms hybrids with C. acanthocarpa var. major, C. arbuscula, C. fulgida (see 6. C. ×kelvinensis), C. leptocaulis (see discussion under 3. C. ×tetracantha), and C. versicolor (= C. ×grantiorum P. V. Heath). Introgression between C. spinosior and C. imbricata occurs in a more or less continuous band from central New Mexico to Chihuahua, Mexico. The hybrids between C. spinosior and C. acanthocarpa var. major are sprawling shrubs with irregular branching pattern and have spine clusters with one or more spines longer than others and fleshy fruits, some with one to few spines per fruit. Chromosome numbers of hybrids are all reported as 2n = 22.</p>
