Note :

1. Walther (Echeveria, 188 - 191, 1972) and accordingly also Kimnach in Illustrated Handbook of Succulent Plants, 2003, classify E. gloriosa as synonym of E. rubromarginata. This is simply wrong as a comparison of the photos on the respective type sheets undoubtedly evidences (see first photo below).

In order to take this synonymisation into account, Walther modified his description of E. rubromarginata accordingly, and he also took into account a plant he himself had collected at Esperanza, Puebla, i.e. a plant not from the type locality of E. rubromarginata near Orizaba, Veracruz, differing from the latter distinctly. Conclusion : Walther's text on E. rubromarginata is of no use at all, and accordingly also Kimnach's summary of it in IHSP, 2003.

2. Plants occurring in Puebla considered to be E. rubromarginata, are much more robust than plants from the type locality in Veracruz, the side-branches of their inflorescences are more numerous and bear more flowers.
