Rhodiola rosea Linnaeus ssp. roanensis (Britton) H. Jacobsen. Common name: Roseroot, Goldenroot, King's Crown. Phenology: Jul-Aug; Aug-Sep. Habitat: High elevation rocky summits, over 5500 feet elevation Distribution: Roan Mountain (Mitchell County, NC) and Grandfather Mountain (Avery County, NC), where nearly (if not completely) extirpated.
ID notes: Dwarfed, high elevation forms of Hylotelephium telephioides, with narrow, nearly toothless leaves, have been confused with Rhodiola rosea ssp. roanensis; they are perhaps readily distinguished only in flower or fruit.
Origin/Endemic status: Endemic
Taxonomy Comments: Additional study is needed to more fully understand the relationships of this and other eastern North American members of the Rhodiola rosea complex, and their most appropriate taxonomic recognitions and ranks.
