Note

1. The rosette diameter of E. subalpina is variable. While plants usually do not branch, the collection from Tlaxcala (San Francisco Temetzontla, Municipality of Panotla, Cerro Cuatlapanga) has smaller leaves and more caespitose rosettes. 

2. Very often the hybrid E. 'Olivine' is distributed under the name of this species.


In habitat, north-east of Esperanza, State of Puebla, under bushes on a steep slope between rocks.
