It is very doubtful if this form is sufficiently well marked from 

 the typical form of the species to call for taxonomic notice, since it 

 sometimes grows with the species and is then seen to pass directly 

 into the specific form; the chief reason for distinguishing the variety 

 is that it commonly grows at higher levels than the species, and in its 

 zone of greatest frequency, the type state is rarely found.
