Mr. T. Edmondston's List of Shetland Plants, 291 



Shetland ; I met him at some distance from Baltasound, and ac- 

 companied him thither ; on the way, as he was questioning me 

 on the botany of the island, I mentioned two plants to him as 

 being (as I thought) rare or peculiar, — the one turned out to be 

 the Pisum maritimum of Linnaeus {Lathyrus pisiformis. Hook. 

 'Br. Fl.'), the other was this species of Arenaria; I named to 

 him the genera to which the two plants belonged, but wished 

 to have his opinion on the species. Next day, in looking over 

 my little collection, we found the specimens of the two plants : 

 Dr. Macnab thought they were new to the British Flora, and 

 he had not seen them before ; he was also of the same opinion 

 as myself as to their genera. I guided him to the localities 

 where I first found the two plants, and we procured abundance 

 of specimens. A few days after, when Dr. Macnab left Unst, 

 I gave him a number of specimens for the opinions of Drs. 

 Hooker and Graham. Dr. Graham at first pronounced it to be 

 nondescript, but was soon induced to change his opinion from 

 seeing a plant in Prof. Hooker's herbarium (gathered by Sir 

 George Mackenzie in Iceland) labelled as Arenaria norvegica, 

 which he thought agreed with the Unst plant. 



I have since botanically examined almost the whole of my 

 native islands, but I have not been able to find a single plant of 

 this species, except in the locality where it was first found by 

 me. I have only further to add, that I have endeavoured to 

 cultivate it by transplanting to a garden ; I have not, however, 

 succeeded, although plants of Cardamine hastulata and Ceras- 

 tium latifolium, under the same circumstances, grew and took 

 root. I have, however, not had an opportunity of trying to 

 raise it from the seed.
