THE PLANTS OF TOKY ISLAND. 265 



Mr. Hynclman's list contained 42 siDecies, but I have enlarged 

 the number to 145 in the following catalogue. This list I have 

 compared with Mr. H. C. Hart's ' List of i^lants found on the 

 islands of Aran, Galway Bay,' * and also with my friend, Mr. A. 

 G. More's ' Eeport on the Flora of Innish Bofin, County Mayo,' t 

 whither I accompanied him in 1875. 



There are 372 species in the Aran list, which embraces three 

 islands containing an aggregate of 10,781 statute acres ; in the 

 Bofin list we find 303 species from an area of 2312 acres ; Tory 

 Island produces 145 species, and contains 785 acres. There are 

 36 species found on Tory not in the Aran list, and 14 not in the 

 Bofin list, but it has been thought sufficient to mention the eight 

 species which occur on Tory and are absent from hoth Aran and 

 Bofin, namely: — 



Haloscias scoticum. Lamium intermedium. 



Carduus pratensis. Lamium incisum. 



Linaria vulgaris. Beta maritima. 



Lamium amplexicaule. Carex vulgaris. 



These are characteristic of the Tory flora. 



There are 11 species I noticed on Tory which do not appear to 

 be mentioned in Mr. Hart's list of the plants of North- Western 

 Donegal. 



Eanunculus Baudotii. Beta maritima. 



Brassica Napus. Juncus acutiflorus. 



Callitriche platycarpa. Juncus compressus. 



Linaria vulgaris. Carex ffideri. 



Lamium incisum. Festuca duriuscula. 



Myosotis csespitosa. 

 Three of these are new to district 11 of the ' Cybele Hiber- 

 nica,' namely, Fiannncidus Baudotii, Linaria vidgaris, and Lamium 

 incisum.. 



In Mr. Hyndman's list before referred to there are four species 

 which I did not notice, Crambe maritima, Erica Tetralix, Gentiana 

 campestris, and Juniperus communis. 



Crambe is one of the rarest Lish plants, and a careful search 

 was made for it unsuccessfully. Erica Tetrcdix and Gentiana 

 campestris were perhaps extirpated by the islanders cutting sods 

 for fuel, or may have been overlooked; Juniperus communis was 

 probably recorded for Empetrum nigrum (see following list). 



It is hardly necessary to analyse and classify the scanty flora 

 of Tory into Mr. H. C. AVatson's " types." The following hst is 

 perhaps more valuable for the negative evidence it affords than for 

 any positive information it supplies. A comparison of the flora of 

 remote islands will not improbably be useful in elucidating the 

 geograiDhical distribution of species ; the plants found on such 

 insulated areas are certainly less liable to be influenced by artificial 

 means of transport than those which grow in districts and counties 

 whose inhabitants are in daily and frequent intercourse.
