Discussion
S. D. McKelvey (1938–1947) wondered if Yucca elata var. verdiensis might be a mountain variety of Y. angustissima. On the other hand, she pointed out the differences between the two taxa and stated that the features of the former bear “no resemblance to those of Y. angustissima.” J. M. Webber (1953) suggested that var. verdiensis is a hybrid between var. elata and Y. angustissima.
