Very little is known about Yucca tenuistyla, and further study is needed. Along with Y. louisianensis, it was treated by S. D. McKelvey (1938–1947) as a part of Y. constricta. The characteristics separating these three taxa are tenuous, and it is possible that Y. tenuistyla is just a variant of Y. flaccida, which includes Y. louisianensis.
