206 THE PLANTS OF TOKY ISLAND. 



As Mr. H. C. Hart lias just coucluded his paper on the flora of 



that portion of the mainland of Donegal opposite to Tory Island, 



a comparison between the uisular flora of 145 species and the 



mainland flora of 530" species can be readily instituted. 



Plants certainly not native are marked thus '■', those possibly 



introduced f, and those probably introduced :[. 



Fuinuncidus Baudutii, Godron. In one j)lace only east of 



Lough Ayes. 



U. hederaceus, Linn. Only in a spring between Portnathralla 



and East Town. 



R. Flammida, Linn. Common and variable. Var. pseudo- 



reptans, Syme, not unfrequent. 



\R. repens, Linn. Common. 



tShiapis arveiisis, Linn. ] t ix- x j it i • x 



Xt^- a- t • r I^ cultivated ground only — colonists. 



\Brassica Acqnis, Lmn. j ° -^ 



Cochlearia ojjicinalis, Linn. Variable ; some specimens very 

 dwarf, and almost var. alpina of Lond. Cat. 

 \Capsella Bursa-paatork, DC. Common. 



[Cramhe maritima, Linn. Is in Mr. Hyndman's list of Tory 

 plants, but not a trace of it could be found, though I 

 searched for it most carefully). 



Viola sylvatica, Fries. In the Rams Hollow, a curious shady 

 depression near the cliffs in which a few i^lants, very rare 

 on Tory, may be found. 



Polygala depressa, Wender. On the elevated portions of tho 

 island, but not common. "P. vulgaris'' of Mr. Hynd- 

 man's list is probably the same. 



Silene maritima, With. Frequent. 



Cerastium tetrandrum, Curt. Not uncommon among rocks north 

 of the lighthouse. 



C. triviale, Link. Not uncommon. 

 \SteUaria media, With. Common. 



Sagina maritima, Don. Very common about the lighthouse. 



8. procuinhens, Linn. Abundant. 

 \Spergula arcensis, Linn. Very abundant in the cultivated fields. 

 Specimens examined belonged to the var. *S'. arrensis 

 (Keich.), i.e., without i3apill£e on the seeds. 



Spergidaria salina, Presl. Common about the lighthouse on 

 damp ground. Probably '* Arenaria rubra'' of Hyndman's 

 hst. 



S. rupicula, Lebel. Common on the rocks about the light- 

 house. 



Ixadiola Millegrana, Sm. Around Lough Ahooey, and in several 



other places. Specimens diminutive. 

 \Trifoliiun prateiiae, Linn. 



T. repens, Linn. Common, and as it occurred on the wildest 

 parts of the island, even on the summit of Tor-more, I am 

 disj)osed to consider it native. 



Lotus coniiculatus, Linn. Sparingly over the whole island. 



* Stated to be 420 (' Jouru. Bot.', n. s., vol. viii., p. 77;, but on counting up 

 Mr. Hart's list carefully this appears to be an error.
