180 THE PLANTS OF THE ARAN ISLANDS. 



grows quite erect, with a strong and woody tap-root, the branches 

 being numerous, thick, and interlaced, and forming a compact 

 bushy mass. I have not yet been able to match it in book- 

 descriptions or herbaria, and doubt its identity with S. herbacea, 

 variable as that is. The glass-worts of our S.E. coasts deserve 

 more attention than thev have hitherto received.

THE PLANTS OF THE AKAN ISLANDS, GALWAY BAY. 



By J. E. Nowers and James G. Wells. 



Many notices have from time to time been published of the 

 plants inhabiting these interesting islands, but, with two exceptions, 

 they have been more or less fragmentary. The exceptions are the 

 lists published by Dr. E. P. Wright* and by Mr. H. C. Hart,t 

 which make much greater approach to completeness than do any of 

 their predecessors. In addition to these, Mr. A. G. More, in a 

 Beport on the Flora of Inish Bofin, \ compares the plants inhabiting 

 that island, composed as it is of Silurian schist, with those growing 

 upon the limestone islands of Aran, and states, apparently on the 

 authority of Mr. Hart's List, that ninety-two plants found on Bofin 

 do not occur on Arran. 



During a stay of a fortnight on these islands, in June, 1890, 

 the writers made a careful investigation of the plants, more 

 particularly of those on the northern one, and the result has been 

 the discovery of forty-one species new to the Aran Islands, no less 

 than thirteen of which were enumerated by Mr. A. G. More as not 

 known to occur there. Classifying them in accordance with Mr. 

 Watson's types, these additions are : — British type plants, 30 ; 

 English, 4 ; Atlantic, 2. 



In Dr. Wright's and in Messrs. Hart and More's papers Senebiera 

 Coronopus is given as occurring in Aran, whereas S. didyma is not 

 recorded, and indeed in the last two is stated not to occur there. 

 We, on the contrary, found S. didyma on all three islands, and in 

 abundance on the northern one ; and only came across S. Coronopus 

 in one spot on the north island. The only probable explanations 

 of this apparent disagreement that we can offer are that S. didyma 

 has by some means been since introduced into Aran and has snread
