V. V. Byalt (pers. comm.) believes that Orostachys ramosissima, here treated as a synonym of O. fimbriata, is synonymous with O. chanetii. If this were to prove true, then O. ramosissima (Maximowicz) V. V. Byalt (Probl. Bot. XX-XXI Cent.: 167. 1998) would be the correct name for the species because Umbilicus ramosissimus (1859) antedates Sedum chanetii (1908).
