alpina in considerable profusion ; Aspidium Lonchitis more abun- 

 dantly than ever. Above our heads, on an inaccessible ledge of 

 rock, the delicate Lloydia serotina was growing in happy secu- 

 rity; while every crevice was filled with the most exquisitely di- 

 vided forms oiAsplenium viride and Cystopteris fragilis. I have 

 little doubt in my own mind that the Woodsia was to be found 

 there as elsewhere. But Williams's intention evidently was to 

 lure us from the spot. He declared it grew below Crib Goch, 

 about a mile or more nearer the Pass, in the direction of Gorph- 

 wysfa, and said he would take us to see it ; but as he wanted to 

 go back to the inn, and we preferred to descend into the Pass, 

 we agreed to meet him halfway up after we had breakfasted, and 

 then go with him to the spot. Of course he did not appear ; and 

 on meeting him a few hours afterwards at the Victoria Hotel he 

 tried to shuffle out of it, but only succeeded so far as to convince 

 'US that he had been intentionally misleading us. So I would 

 give my humble advice to all future explorers in those regions to 

 trust to nothing but their own eyes and accurate observation of 

 the various geological strata while searching for plants. I may 

 mention that Hymemphyllum tunbridgense occurs in company 

 with the Wilsoni along the banks of the stream, halfway between 

 the Waterfall and the Victoria Hotel at Llanberis. 



The finest specimens of all, however, that I have ever seen of 

 this beautiful little Pern were in the Vale of Pestiniog, on the 

 south bank of the wooded glen immediately below the church. 

 Aspidium recurvum or Fmnisecii [Lastrea cemula, Brackenridge) , 

 or whatever Botanists may choose to call it, occurred also most 

 abundantly in the same spot. With respect to other of the rarer 

 Ferns, I may mention that I found Asplenium marinum sparingly 

 on the Great Orme's Head, halfway down the cliff", also abun- 

 dantly on the cliffs between Port Madoc and Criccieth in com- 

 pany with A. lanceolatum.
