informed me that he and Mr. M'Cutcheon had gathered the 

 same plant in the same locality in 1902 and transferred 

 specimens to their gardens where it grows like a weed. 

 He also said that it was believed in the district that the 

 late Dr. Grierson of Thornhill had planted this and other 

 rare alpines in the neighbouring glens. 



This suggestion may or may not be correct, but the 

 plant has apparently maintained itself for some twenty 

 years in this particular locality. Considering that the 

 Rev. Dr. Singer recorded A. alpina, L., for the county in 

 1843, it is perhaps advisable, in order to prevent contro- 

 versy in the centuries to come, that these facts should be 

 placed before the Society.

This paper forms a continuation of four papers on the 

 same subject, one of which I read before the Scottish 

 Natural History Society on 4th April 1895, and which was 

 published in " The Annals of Scottish Natural History," 

 No. 15, pp. 178-181 (July 1895), and tlic other three before 

 the Botanical Society of Edinburgh on 15th January 1914, 

 10th June 1920, and l7th March 1921, and Avhich were 

 published in the Society's " Transactions," vol. xxvi, pp. 

 207-217 (1914), and vol. xxviii, pp. 28-42 (1920), and 

 pp. 51-66 (1921), respectively. Most of the plants men- 

 tioned in this paper were collected by me during the year 

 1921. 



Before and after the publication of the second edition of 

 Watson's "Topographical Botany," in 1883, several of the 

 plants mentioned in the following list have been recorded 

 from Orkney by me and other botanists; but as the value 

 of botanical records is greatly enhanced by the possession 

 of authentic specimens, I have included in this list the 

 names of all specimens in my herbarium, which are either 

 additional to or confirm doubtful records of the plants
