Taxonomy
Trelease described the genus Samuela based on two species, Samuela faxoniana (now Yucca faxoniana) and S. carnerosana (now Yucca carnerosana).[6]
The 2025 paper "Phylogenetic relationships and character evolution in Yucca (Agavoideae, Asparagaceae)" by Ayala-Hernandez et al. analyzed genetic data and found Yucca carnerosana and Yucca faxoniana to not only be distinct species, but of different lineages and not closely related to each other.
