|discussion=<p>Plants of <i>Opuntia polyacantha </i>var.<i> erinacea</i> with very long, wavy hairlike spines have been treated as O. ursina or O. erinacea var. ursina. Such plants, however, occur at the original (type) locality for var. erinaceae, and the characteristic spines may appear on the oldest stem of otherwise straight-spined plants. The name <i>Opuntia</i> erinacea has been widely misapplied to some plants of other varieties of <i>O. polyacantha</i>.</p>
