1 6 The Irish Naturalist. Jauuary, 



The rediscovery in Ireland oi Fissidcjis tamarindifolius, only 

 once before found in our island, and that over a century ago, 

 possessed for me much interest. It is described in Turner's 

 lihiscologicc Hibcr7iiccd Spicilcgiiwi (1804) as having been de- 

 tected in Cullen's Wood, Co. Dublin, by Dr. Whitley Stokes, 

 whose name is botanically perpetuated in Hypnum 

 i^Eurhy7ichi2U)i) Stokesii. 



In like manner, Pottia bryoidcs and WHsia crispa, two other 

 rare species which it has been my fortune to meet with, had 

 not been seen in Ireland for very many years. 



Though rare in Ireland — it had been reported from only two 

 other localities in Ulster — it may be confessed that much of 

 the delight in gathering Fontijialis squamosa in the River Bann 

 was due to a personal reminiscence. It recalled to mind the 

 first and only other time I had seen it growing. That was in 

 a North Yorkshire moorland beck, now fifty years ago, in the 

 days of youthful botanical ardour, the pleasure being shared 

 by others, who were then my frequent companions on excur- 

 sions, and whose friendship I yet enjoy. But this is a digres- 

 sion that will, perhaps, be forgiven. Templeton found the 

 plant in 1800 in the River Faughan, Co. Derry, It has often 

 been looked for in the mountain streams of Co. Antrim, 

 where it might be expected, but has never yet been found in 

 that county.

 rostellata) for Ireland, Ulster and counties of Ulster, so far as 

 I know, are : —
