The last statement is one which will commend itself to most of 

 your readers. A specimen is in Miss Palmer's collection.

" Said to have been found by Don on Werron Hill and East 

 rocks, Loch Brandy, Clova, but no doubt Sibbaldia procumbens 

 has been mistaken for this American plant." Boswell, E. Bot. 



" Incog. The late Mr. G. Don appeared quite confident that he 

 had seen or collected this species in Forfar, and there is even a 

 specimen preserved in Sm. Herb which is labelled as though 

 actually collected on the Hill of Werron in that county by Don, 

 with the date of April 3, 1809. Is it possible that Mr. Don could 

 have mistaken plants of Sibbaldia or Potentilla Fragariastrum for 

 this species, and have sent or pointed out to Smith an example of 

 P. tridentata as being the same species he had seen on Werron 

 or other hills ? I do very much suspect that this is the true solu- 

 tion of some of the mystery which attaches to several of Mr. Don's 

 habitats — namely, that intending to send or show the same species, 

 he or Smith inadvertently confused it with some other species." 

 Cyb. Brit., 1*348. 



" P. tridentata, justly regarded by Mr. Don the most beautiful of 

 its genus, was found by him on a mountain called Werron, in 

 Angus. Linn. Trans, x. 343." Sm. En. Flora. Vol. xxxiv. 

 1389. 



u This hill has since been searched by Mr. Kerr and a party 

 from Montrose, but without success. It may, however, have 

 occurred only in one spot, and such a spot may elude again and 

 again the keenest researches of the mountain rambler. An 

 authentic specimen, gathered by Don, is in Mr. Kerr's herbarium; 

 and there is also a specimen among the remains of an herbarium 

 formed by Mr. Douglas Gardiner in 1813, which had likely been 

 given to him by Don, as they were intimate friends." Gard. Fl. 

 Forfar. 



"An American plant, said to have been found at Clova ; was 

 probably Sibbaldia." Bab. Man. vii. 103. 



At a meeting of the Edinburgh Botanical Society, March 14, 

 1850, Mr. M'Nab exhibited a dried specimen of P. tridentata sent
