THIS is one of our rarest ferns ; for a number of years 

 Arthur's Seat was the only locality where it could be obtained with 

 anything like certainty. Mr. Wilson and Mr. C. C. Babington 

 have recently gathered it in Caernarvonshire, although very 

 sparingly, and in August, 1838, I had the good fortune to find it 

 in luxuriant profusion on a wall by the road side going out of 

 Llanrwst, towards Conway; the station is on the left hand, 

 exactly opposite a farm-yard, and about a mile from Llanrwst. 

 The plant is very obvious, and may be procured without diffi- 

 culty ; the stones in the wall are Ioose 3 so as to admit of their 

 being readily removed and returned to their places. Although

 one of our very rarest ferns, I must accompany the record with
