 Vallee d'Ormonts ; Payeme (Charp.) ; — Belmont and other places 

 near Lausanne ; Rochers Nez ; Devens.

M. Charpentier doubts this species having been ever found in

 for it.

 mous with C. rugosa. This variety or form appears to be 

 very common and widely spread in Switzerland.

 another variety of the same species.

 is another variety.
