Obs. A large proportion of the species of this genus inhabit the 
Zona montosa superior and the Zona subalpina, in some instances ex- 
clusively. In Z, they become much more rare, and above the line 
where forests disappear, Hypna can barely be said to exist. Of the 
rupestral species, the following were observed only on calcareous 
rocks or soil: H. abietinum, recognitum, striatulum, murale, crassi- 
nervium, Vaucheri, Teesdalii, tenellum, rugosum, commutatum, poly- 
morphum and depressum. Of the other species, several are occa- 
sionally found on trees, but they all grow with equal facility on 
rocks or on the ground.
