Following Bischofberger and what I have seen online, the forms known in cultivation are summarized below. Note that there have been at least 8 different observances of this plant in the wild; each of these can potentially have produced numerous forms, also Mexican nurseries may have made independent, unreported collections. Sedum adolphi 'Golden Glow' - This is the plant which has masqueraded as the 'real'S. adolphi in all publications between the 1950's to 2010. It is possible that this is a hybrid of some sort, according to some. In some collections it has been maintained under the name x. Graptosedum 'Golden Glow', which gives it this cultivar name fide Bischofberger [2010]. Clausen in 1959 makes it clear that there were a number of x.Graptosedum hybrids being made by Californian nurseries at this time; he names at least three possible S. nussbaumerianum x. Graptopetalum hybrids. Note that he himself did not consider his S. adolphi 'Golden Glow' a x. Graptosedum hybrid, he thought it was the real S. adolphi as opposed to what he thought was the real S. nussbaumerianum! Existing in California and New York Clausen names an infertile G. paraguayense x S. nussbaumerianum (1950 to 1959), a possible G. amethystinum xS. nussbaumerianum (1949), and an unlikely G. paraguayense x S. nussbaumerianum which was probably a hybrid with another species of Sedum. According to me, if 'Golden Glow' were truly a hybrid, it would likely be with the closely related S. lucidum, because 1) the inflorescence is similar in both species, 2) the leaves seem to have a similar lustre as S. lucidum, 3) S. lucidum has decumbent forms with the same dense rosettes, 4) the leaf shape is intermediate between the two, 5) the leaves of this form stay on the branches for quite a long time, this is also characteristic of S. lucidum. S. lucidum has 2n=68, S. adolphi has 2n=64 so if this is a hybrid it would be an infertile 2n=66. It has been circulating at least in Europe since at least 1983, and in the USA since at least 2009. One wonders how this plant relates to the 'lost' forms, but it is not Bitter's nor Hamet's original forms. The denser leaf growth at the apex gives this form a nice rosette, which can be used to I.D. it. Syn: x. Graptosedum 'Golden Glow' S. adolphi fide 't Hart & Bleij S. adolphii fide Stephenson S. 'Golden Glow' Sedum adolphi "Coppertone" - collection numbers: Uhl2497, HBG40419, ISI1682. Got its name from Magic Growers Nursery in California in 2002. First commercially distributed via the International Succulent Introductions in 1986. Syn: S. nussbaumerianum as described by George Bitter in Notizblätter des Botanischen Gartens Berlin-Dahlem [1923] from plants found growing at the Bremen Botanical Garden. Cotyledon rosettifolia Hort. Berlin-Dahlem S. nussbaumerianum 'Bitter' - confusion with the plant name author as cultivar name having occurred in France & UK before 2004. Sedum adolphi - Hamet's original 1912 form - possibly lost to cultivation. Sedum adolphi "Nussbaumerianum" - The original plants used by Bitter in Germany in 1923, grown from seed from Purpus from Mexico, almost must be the same as grown in Spain after WWII, and these may still exist. Sedum adolphi 'Lecouona Sisters' - The Lecouona sisters were succulent collectors living in Banderilla, Vera Cruz. According to Clausen [1959], a clone grown by them received by him from an intermediate source at the New York Botanical Garden (thus probably dating the clone a few years earlier than 1959), was distinguished by being intermediate in length of leaves between his understanding of S. adolphi (big leaves) and S. nussbaumerianum (smaller, greener). Sedum adolphi 'Oranges' syn. S. nussbaumerianum 'Oranges' - see here. As a distinct selection according to the vendors, this might be best awarded a cultivar name, in my opinion. Sedum adolphi "Red" - This plant from California may or may not be distinct. Seehere. En definitiva variabilidad enorme y no se sabe quien es quien.... para el señor del enlace anterior q como veo Fer no te has molestado en leer lo que nosotros tenemos como nussbaumerianum es adolphi y lo que tenemos como adolphi es adolphi Golden Glow Y una cantidad de hibridos y cultivares....por cierto que parece ser quese ha naturalizadoen Fuerteventura y en el Sur de España ...eso me ha parecido leer

Mira cape lo que dice Margrit aquí http://crassulaceae.net/sedummenu/50-speciessedum/1042-sedum-adolphi-and-sedum-nussbaumerianum-en en el antiguo ICN según ella lo que nosotros conocemos por adolphi es un impostor...que unos llaman Sedum adolphi y otros XGraptosedum Golden Glow, para ella es un Sedum que se debería llamar Sedum Golden Glaw y el autentico adolphi es el que nosotros conocemos como nussbaumerianum... el dibujo de Hamet que se pone en esa página deja clarisimo que el adolphi es el de las hojas estrechas y ahora vuelve a contarme lo del primo Alzh
Chic@s, me teneis así voy a tener que hacer una carrera pa enterarme bien de todo, questoy yo mu verde en estos temas Lur, creo que lo voy a bautizar con el nombre compuesto de adolphinussbaumerianum (edito, que molvide de ponerle lo de XGraptoserum delante) ¿no es mío? pues desde ahora mismito se llama como a mí me dé la gana!! y al que me discuta le monto un pollo!! ea!!
