Systematics Section / ASPT Santos-Guerra, Arnoldo [1], O'Leary, T. Ryan [2], Mort, Mark E. [3]. Phylogenetics and evolution of Aichryson (Crassulaceae) inferred from chloroplast and nuclear sequence data. Aichryson (Crassulaceae) is a genus of annual or perennial herbs which traditionally comprised approximately 13 species nearly endemic to Macaronesia. Recent molecular phylogenetic analysis has provided moderate support to increase the number of recognized species to as many as 17. The addition of ten new chloroplast regions and one new species to the phylogenetic analysis provides the largest data set ever compiled for a Macaronesian genus of succulent plants. This, in turn, provides strong support at critical nodes allowing for a revision of the biogeographic and character evolution hypotheses and justification for a taxonomic revision of the A. pachycaulon spp. group.
