 | | The Macaronesian clade (Crassulaceae) includes four genera, Aeonium, Aichryson, Greenovia, and Monanthes, that are largely endemic to the Canary Islands. |
 | | The monophyly of this clade has been supported based on phylogenetic analyses of Crassulaceae; however relationships within this clade remain uncertain. |
 | | Aeonium, the largest genus of Canary Island Crassulaceae, comprises species that are highly diverse in growth form, including rosette trees, candelabrum shrubs, highly-branched shrubs, and woody rosettes. |
