Note :

The plant Rose has described as Echeveria tenuis has never been recollected in Mexico. Whether it has ever been in cultivation is unknown. 

Walther on his part also wrote an Echeveria tenuis description, however the origin of his plant is totally unknown, the only information about it is the fact that he had received it from F. Schmoll, Cadereyta, Queretaro. Therefore his description is of no use and is to be ignored.
