existed as to the correct identification of the barren plant. 

 Mr. Dixon obligingly assures me that ''Your Fissidms is cer- 

 tainly identical with the English F. ritfulusP 



At the same place there was noticed an unusual alga which, 

 in my examination of similar situations, I had never seen be- 

 fore. It proved to be the rare Cladophota csgagropila, of which 

 a separate note is given on another page. It may be antici- 

 pated that yet other rarities will be found there. 



The unexpected revelation of Weisia calcarea on a wall at 

 Lenaderg seemed like a vision of delight." Not only is it a 

 very beautiful little plant, but is as rare as it is interesting. 

 Moore, on the authority of the late Isaac Carroll, records it 

 doubtfully from Cork, the only other Irish county in which it 

 is known to occur. Not depending on my own examination 

 of some of Carroll's original specimens I sent them to Mr. 

 Dixon, who says " The Cork plant is also quite correct." 



Of mosses met with on the coast there are two or three 

 which, I think, may be accounted worthy of special mention. 

 Thus, Trichostomum 77tuiabilc, van cophocarpum, rare in Britain, 

 had not previously been indicated, as such, from Ireland. Mr. 

 Dixon, however, is strongly convinced, by his examination of 

 Original examples, that the plant found by Dr. I/indberg at 

 Killarney in 1873, described by him as Mollia lutescenSy and, 

 under that name, figured as a separate species in British Moss 

 Flora, is the same as the present plant. Other noteworthy 

 mosses from Newcastle are Barbula recurvifolia and Weisia 

 crispata. The former, Moore knew only from counties Kerry 

 and Sligo, and Weisia crispata, which is one of the new 

 British species described in the recently published second 

 edition of Studenfs Handbook of British Mosses, was before 

 known as Irish from a single station in Donegal^ 



Very gratifying, too, was it to collect at Ringfad Point a 

 plant, which, following the nomenclature of Mr. Dixon, is be. 

 lov/ set down 2iSAmblystegium filicinwn, var. Vallisdauscs. In 

 Ireland, I think, it had been found only in the Shannon, 

 whence it was lately reported by a lady botanist^. Authors
