The intricate story of the binomial “ Sempervivum reginae-amaliae ” was discussed in detail by Raus (2018). There is, however, some uncertainty in respect to the “validatation” performed by Boissier (1888) as claimed by Raus. Though Boissier mentioned “diagnostic characters” referring to the Guiccardi exsiccatum these only served to show that S. reginae-amaliae must be assigned to “sect. Eusempervivum ”. But Boissier adds with respect to this name that he is not able to distinguish this specimen in a dried state from S. tectorum (“Hoc autem saltem ex sicco a S. tectorum distinguere non valeo.”).
