The Telephieae{{efn|The name Telephieae may be [[Nomen illegitimum|illegitimate]] in this context, since it has been previously used as a synonym for [[Caryophyllaceae]]{{sfn|Reveal|2012}} }} genera consist of former infrageneric taxa of ''Sedum'', and are distributed primarily in East Asia, but with a few species found in Europe and N America (''Hylotelphium''). Defined by 5-[[merous]] flowers, free [[petals]], flat, [[Dentate leaf|dentate]] leaves and tuberous roots or thickened [[rhizomes]]. Leaves usually in rosettes, except ''Hylotelephium'', petals often spotted, autumn flowering. The taxonomy remains unstable, with species ''Orostachys'' embedded within both ''Meterostachys'' and ''Hylotelephium''. Neither ''Hylotelphium'' nor ''Orostachys'' are considered monophyletic. But of the two [[section (biology)|sections]] of the genus, section ''Appendiculatae'' appears monophyletic and sister to ''Meterostachys''. ''Kungia'' is a segregate of a non-monophyletic ''Orostachys'' and appears to be a sister to ''Sinocrassula''.{{sfn|Messerschmid et al|2020}}

* ''[[Hylotelephium]]'' <small>H.Ohba</small> c. 27–30 sp., N hemisphere

The Umbeliceae occur mainly in temperate areas of Asia, flowering in spring to early summer, with about 4−5 genera and 100 species. The tribe consists of two subclades. The first, Phedimus/Rhodiola, includes ''Phedimus'', ''Rhodiola'' and ''Pseudosedum''. The latter has been included within ''Rhodiola'', or treated as sister to that genus. ''Aizopsis'' is included by some authors in ''Phedimus''. This subclade contains about 88 species found predominantly in Asia, but some species of ''Phedimus'' and ''Rhodiola'' in Europe and some ''Rhodiola'' in N America.{{sfn|Messerschmid et al|2020}}
