7. Jungermannia, Linnaeus. 



Obs. Of the Jungermannice observed in the Pyrenees, Jg. acuta and 

 Wilsoniana have their normal station on calcareous rock ; Jg. exsecta, 

 ventricosa, curvula, incisa, divaricata, reclusa, curvifolia and setacea 

 were gathered only on decayed wood ; the remainder are chiefly glareal 

 or viatical, and some of them were also occasionally seen on decayed 

 wood. It will be remarked that those species which in the Pyre- 

 nees occupy semiputrid trunks are the same which inhabit heaths 

 on the plains and hills of the north of Europe. The species which 

 approaches nearest the snow-line is Jg.julacea.
