Many thanks for your recent e-mail searching for information on Hylotelephium.
This generic name was erected some years ago, in 1977 to be precise, by H. Ohba, with Sedum telephium as the type. Hylotelephium embraces the whole relationship around Sedum telephium, i.e. numerous flat-leaved rhizomatous or tuberous-rooted “Sedum” species. Some of the more familiar Sedums which are now classified as Hylotelephium are H. anacampseros, H. cauticola, H. ewersii, H. pluricaule, H. populifolium, H. sieboldii and H. spectabile, and of course H. telephium.
With the exception of H. populifolium, which to me appears misplaced here, the group is quite neatly defined and easily recognizable. The genus will also be accepted for the forthcoming Succulent Plant Lexicon.
For resolving future similar problems, I would recommend my publication, “List of Names of Succulent Plants Other Than Cacti” published by RBG Kew, embracing the period 1950-1992, as taken from Rep. Pl. Succ. This booklet contains all new names published in the period mentioned, and gives full literature references to the places where new species, etc. and combination have been published. As far as I know, the book is still available from RBG Kew, and perhaps also from US-American booksellers.
Note: The booklet referred to is listed in Worldcat, which also gives the names of the authors:
List of names of succulent plants (other than cacti) from Repertorium plantarum succulentarum (1950-1992)
