Twentyfour gametophytic characters were evaluated to identify the phylogenetic relationships among the known species of Aloinella . A previous study proposed that Aloinella derived from Aloina , mainly by stem elongation and leaf character reduction. In this analysis, it was observed that the most plesiomorphic species in the Aloina and Aloinella clades occur in Mexico. The distribution and the cladistic study support the view that both genera are monophyletic, but the phylogenetic relationships of the species may need further analysis with the inclusion of sporophytic characters. Sporophytes are infrequent in Aloinella . The smoothwalled A . cucullatifolia , A . boliviana , and A . cucullifera form a group that separates cladistically from the papillose taxa A . catenula , A . venezuelana , A . galeata var. galeata , and A . galeata var. andina .
