Discussion

L. D. Benson (1982) grouped all large, yellow-spined plants in the Texas region under Opuntia lindheimeri. Plants known as O. lindheimeri var. lehmannii have large, wavy stem segments that are broader than long. Opuntia lindheimeri var. tricolor (Griffiths) L. D. Benson is a morphotype with long, yellow spines to 75 mm; and O. subarmata Griffiths is a morphotype with spineless or nearly spineless stems.

Although Opuntia engelmannii var. lindheimeri is a hexaploid, like the rest of O. engelmanni, several individuals were recorded as 2n = 22, 44, and ca. 44; however, such numbers require taxon verification.

Opuntia engelmannii var. lindheimeri hybridizes with O. stricta, forming hexaploid O. ×alta Griffiths, and with O. macrorhiza Engelmann, forming pentaploid O. ×edwardsii V. E. Grant & K. A. Grant.
