From studies in DNA and molecular systematics, T. H. M. Mes (1995) concluded that Aeonium and these related genera probably evolved from North African Sedum-like ancestors and are only more distantly related to Sempervivum. He thought that the wide range of growth-forms in Aeonium, including the woody habit, is derived from herbaceous ancestors.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Rosette leaves 50-75, blade bright green, 5-9(-15) cm, 1.5-3 mm thick; petals 9-11, spreading, bright yellow. |[[Aeonium arboreum|Aeonium arboreum]] |-id=key-0-1 |1 |Rosette leaves 15-25, blade gray-green, 3-6 cm, 2-5 mm thick; petals 7-9, erect, cream. |[[Aeonium haworthii|Aeonium haworthii]] |} </div></div><!-- -->{{#Taxon: name=Aeonium |author=Reid V.
