WRIGHT ON THE FLORA OF THE ISLANDS OF ARRAN. 105 



The inhabitants are indebted altogether to the mainland for their 

 supply of fuel, and this supply comes in the form of turf from the im- 

 mediate neighbourhood of Eoundstone and Bertraghboy Bay. To this 

 circumstance I am inclined to ascribe the appearance of patches of such 

 plants as Senebiera coronopus and Urtica urens about the villages of Kil- 

 ronan and Kilmeany. 



The following species are enumerated as additions to the Flora of 

 District 6: — 



Ranunculus heterophyllus (Sibth.), var. trichophyllus (Chaix). 



Sisymbrium officinale. 



Cochlearia officinalis. 



Apium grayeolens. 



Silybum marianum. 



Suaeda maritima. 



Salsola kali. 



A list of the principal detached papers relating to the Flora of Ire- 

 land is given in the Preface to the " Cybele Hibernica," pp. viii. to 

 xiii., and in it will be found references to the papers by Mr. W. 

 Andrews, Dr. D. Moore, F. L. S., Mr. Leslie Ogilby, and Professor D. 

 Oliver, F. E. S., on the Flora of the Arran Islands. 



In conclusion, and as some slight apology for the incompleteness of 

 the above Notes on the Flora of the Arran Islands, I may mention, that 

 they were made under very disadvantageous circumstances, as, save for 

 one day, the weather during the whole of my sojourn at Kilronan was, 

 even by the natives, considered very bad. Heavy rains all night and until 

 the forenoon, strong gusts of wind continually driving in from the west 

 or north-west, made collecting and drying plants oftentimes a work of 

 difficulty ; still, however small, I trust these Notes may be considered 

 as a contribution towards making our knowledge of the distribution 

 of the Irish Flora complete. 



Dr. Moore said he would not detain the meeting at that late 

 hour by any lengthened remarks on the paper Dr. "Wright had just 

 read, which contained much interest for those who studied the Flora of 

 this country, as well as for those who studied the geographical distri- 

 bution of plants in the British Isles. Hitherto it had been too much 

 the custom for authors of papers on similar subjects to mention the 

 names of the plants only which they had observed when on such 

 botanical rambles as Dr. Wright had given a sketch of this evening ; 

 but he had treated the matter in a more philosophical manner, by first 

 giving us an account of the geological structure of those outlying is- 

 lands, compared with the formations on the nearest coasts of the main- 

 lands of the counties of Galway and Clare, with a further comparison 

 of the plants growing on the Arran Isles and adjacent coasts. In this 

 way an extensive field for reasoning on the subject was opened up. 

 He has ably pointed out that the Flora of Arran partakes more of that
