Hab. — -Bantry, South of Ireland, Miss liiitchius (Herb. 

 Mitten). 



The only known station. 



Obs. — Mr. Mitten detected this fine species in a collection 

 made many years ago by the late Miss Hutchins in the South of 

 Ireland. It is abundantly distinct from either F. punctata, Tayl. 

 or P. spinidosa (Dicks.), with which it is nearest allied. 



I am indebted to Mr. Mitten's description for most of my 

 notes of the species.
