There seems to be no doubt that this is Willdenow's species, as it 

 agrees with the description. It is certainly also Harvey's plant.

 A plant cultivated in 1837 in the Berlin Botanical Gardens, and 

 preserved in the Herbarium of the Berlin Botanical Museum, named 

 Crassula squamulosa, is Cr. scabra, L. ; but no reliance can be placed 

 on the naming of this specimen, as it was preserved a quarter of a 

 century after Willdenow's death.
