Note :
When Walther wrote his description of E. lozanoi (Echeveria, 151, 1972) plants of this species were not extant any longer, however there were hybrids which wrongly bore this name. He admits that he did not know the true species and that he had to content himself with describing it on the basis of the type specimen and Rose's text. Nevertheless he added specifications he could not possibly have gained from the type sheet - i.e. are pure inventions / lies. So his already superfluous text is of no use at all and accordingly also Kimnach's text in the Illustrated Handbook of Succulent Plants, 2003, based on Walther.
