DISTRIBUTION OF BRITISH PLANTS. 339 



The next group of flowers (No. II.), which characterize 

 the south-west of England and south-east of Ireland, though 

 "not met with elsewhere in the British Isles/' are "inti-

 Isles, but amongst which the group of plants to be after-

 by Mr. Babington. One of the Leguminous family comes 

 next, Sand Joint-vetch (Arthrolobium ebracteatum) ; one of 

 the Composite family, called the Jersey Star-thistle (Cen- 

 taur ea Isnardi) ; a species of Toadflax, Linaria Pelissenana; 

 a kind of Viper's Bugloss, JEchium violaceum, strongly re- 

 sembling Echium vulgare, with its prickly leaves and pretty 

 pinkish-blue bell-blossoms, except that it is rather a larger 

 plant, with the stem branched, instead of simple, and the 

 upper leaves heart-shaped and slightly clasping the stem ; 

 the blossoms too, as the name implies, are of a more violet-
