Everywhere in arctic regions this species has an inclination 
to get concave leaves, which are smaller and with shorter lobes. 
The colour is commonly more or less red-brown and dark, the 
leaf-cells and the cuticular-cells of the stem are shorter. There 
exists howewer a gradual transition between these forms and the 
main-species.

This species varies in the same manner as Cephalozia bicuspi- 
data, but apparently in still higher degree. Probably one or other 
undescribed species is hidden amongst all these more or less 
disagreeing forms.
