|discussion=<p>In Arizona, California, and New Mexico, <i>Opuntia engelmannii </i>var.<i> engelmannii</i> hybridizes with <i>O. phaeacantha</i> yielding numerous named and unnamed hexaploid forms, including O. wootonii Griffiths; the various intermediates have 2n = 66. Hybrid swarms occur in both Zion and Grand Canyon national parks; these plants were perhaps brought in to the parks by native peoples as a food source and they are associated with agaves also believed to have been imported.</p>
