TaxonomyHylotelephium-clade: 5 genera Hylotelephium, Orostachys, Meterostachys and Sinocrassula, also remains uncertain. In all phylogenies Hylotelephium and Rhodiola clades formed unresolved polytomy. It could not be ruled out that these clades have common ancestry but it is likely that their divergence was fast and could not be traced with the markers applied.
Molecular data fully confirmed the distinctness of Hylotelephium, Orostachys, Rhodiola, Phedimus and Aizopsis from Sedum where they were formerly classified.
