It is thus dealt with in Species Plantarum, ed. 2 (1793), p. 904 :—

I have examined the specimen in the Linnean herbarium. 

 Being rather young, and only in flower, it is less valuable for 

 reference than the type-specimens of C. officinalis, C. danica, and 

 C. anglica; the root-leaves are also mostly withered, and in poor 

 condition. Still, the size and habit of the plant are sufficiently 

 well shown, and it agrees well with the description, as far as the 

 material goes. 



Although expressly mentioned by its author as growing in 

 Norway and Iceland, this species is ignored by Nyman, Consp. Flor. 

 Eur. ; and Hartman, Handb. i Skand. Flora, ed. xi. p. 204, remarks, 

 under C. officinalis: — "To this, without doubt, belongs the C. 

 groeulandica L. given for Norway in Sp. PI" I strongly suspect," 

 however, that Linne was correct, as it is improbable that a native 

 of the N.E. coast of Scotland should really be absent from the 

 Norwegian shores. 



The first discovery of the true plant in Britain was by Mr. 

 W. H. Beeby, who found it in the Shetlands in 188G, the station 

 being on low rocky cliffs. In 1890 Mr. F. J. Hanbury and myself 

 came across a curious form of scurvy-grass on the beach at Loch- 

 inver, W. Sutherland, which we recorded as C. danica, though it 

 was very unlike all the specimens of danica which we had seen. 

 Having subsequently looked at the type of C. groeulandica, I began 

 to suspect that my previous notions of that plant were all wron°- ; 

 and accordingly, on meeting with a quantity of the same form last 

 summer near Tain, E. Eoss, I gathered a fair amount, and sent 

 home plants for cultivation. Specimens from both places were 



forwarded by Mr. Hanbury to Prof. J. Lange, who confirmed them 



as true C. groeulandica . I may add that Greenland specimens at 

 Kew are a very good match*
