XLL GYROPHORA (Ach.) Nyl. 



The species of this genus are by no means well represented 

 in Lake Westmorland, and in this respect the flora of this 

 part of the county compares unfavourably with that of the 

 higher part of Teesdale at Cronkley Scar and Falcon Clints. 

 On most of the higher passes and mountains, the rocks bear 

 a few straggling and poorly-developed plants of G. cylindrica^ 

 in some places accompanied by G. erosa, in others by 

 G. polyphylla \ but they are nowhere abundant, while as 

 specimens their development leaves much to be desired. G. 

 proboscidea occurs on Cross Fell, and will most probably be 

 found on the Westmorland portion of the Pennines, but I have 

 not met with it among the lake mountains of the county.

 Syn., ii, p. 13; Leighton, Lich. Flora, p. 148.

 the type.
