7iorvegica. This interesting addition to the British Flora 



is confined, so far as I know, to the serjientine formation around 

 the Bay of Baltasound in this island. Its specific description is 

 as follows: — Root fibrous, long; stems numerous, branched,

 ovate ; calyx-sepals five, fleshy, glabrous as the leaves. Very 

 abundant on the gravelly barren hills to the north of the bay, 

 growing nearly on a level with the sea, along with Cerastium 

 latifolium and Cardamine hastulata, which, with the exception of 

 Statice Armeria and Plantago maritima, are almost the only 

 plants to be found in its vicinit}\
