Barrington — On the Flora of the Blasket Islands. 373 



The eight species peculiar to the Blaskets, and -which have not 

 been observed on any of the other islands, are — 



Cardamine sylvatica. Lnzula sylvatica. 



Lychnis githago. Carex disticha. 



Stellaria graminea. ,, pilulifera. 



Scilla nutans. Hymenophyllum unilaterale. 



The occurrence of Luzula sylvatica in abundance, and SciUa nutans 

 in tolerable plenty on a marine cliff on the west coast, is certainly 

 unusual. Carex disticha grows on the summit of the Great Blasket 

 (Croaghmore), 961 feet. 



That there should be 130 species on the Arran Islands, in Galway 

 Bay, not recorded from any of the other groups, is due to its much 

 larger and more diversified surface as well as its limestone forma- 

 tion. 



There are only seventy-two species which occur on all the islands. 



The following plants, observed on the Blaskets, belong to Mr. H. C. 

 Watson's "Atlantic Type" :— 



Lavatera arborea. Crithmum maritimum. 



Sedum anglicum. Scirpus Savii. 



Cotyledon umbilicus. Hymenophyllum unilaterale. 



Saxifraga umbrosa. Nephrodium semulum. 



One species, Koeleria cristata, is new to district No. 1 of the Cybele 

 Hibemica. 



Plants which elsewhere are certainly native appear to be intro- 

 duced on the Blaskets, as they are confined to the cultivated ground 

 or its neighbourhood. 



Though scanty, the flora of the Blaskets is not without interest. 

 The extreme westerly position of these islands and their situation off 

 the coast of Kerry, with their genial climate and characteristic vege- 

 tation, make a list of their species useful, as affording materials for a 

 comparison with the other island floras, which the tabular catalogue 

 will, I trust, prove useful in facilitating.
