==Taxonomy== Trelease described the genus ''Samuela'' based on two species, ''Samuela faxoniana'' (now Yucca faxoniana) and ''S. carnerosana'' (now ''Yucca carnerosana'').<ref>{{cite web |title=FNA: Yucca faxoniana |url=https://floranorthamerica.org/Yucca_faxoniana |website=Flora of North America}}</ref>

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. <ref>{{cite journal |last1=Ayala-Hernández |first1=María M. |last2=Fehlberg |first2=Shannon D. |last3=García-Mendoza |first3=Abisaí J. |last4=Solano |first4=Eloy |last5=García-Sandoval |first5=Ricardo |last6=Samain |first6=Marie-Stéphanie |title=Phylogenetic relationships and character evolution in Yucca (Agavoideae, Asparagaceae) |journal=Phytotaxa |date=2025 |volume=687 |issue=2 |pages=176–200 |doi=10.11646/phytotaxa.687.2.2 |bibcode=2025Phytx.687..176A |url=https://phytotaxa.mapress.com/pt/article/view/phytotaxa.687.2.2}}</ref>
