Note :

The name Cremnophila tetzmitlia was first mentioned in Las Crasuláceas de Mexico, vol. II, p. 41, 2019, compiled by Jorge Meyrán Garcia. Not only is the publication itself invalid, since it does not contain a Latin or English diagnosis, nor is a type indicated, but it is completely superfluous, since it is only a redescription of a paler clone of C. nutans.
