174 ANNALS OF SCOTTISH NATURAL HISTORY 



SAX I FRAG A C^ESPITOSA, L., AS A SCOTTISH 



SPECIES. 



By ARTHUR BENNETT. 



DR. WILLIAMS' note (I.e. p. 109) on this interesting species 

 seems rather bare, and I propose to offer a few notes on its 

 distribution in Scotland. 



Dr. Trail in his ' Top. Bot. of Scotland,' " Ann. Scot. N. 

 Hist." (1898), 1 68, gives, 



90?. 92?. 94. 96. 97. In 'Add. and Corr.,' I.e. 

 (1906), p. 40, no further note is added. 



90. FORFAR. 



This seems to have been recorded on the supposition 

 that one of Don's plants was to be referred here. 



92. ABERDEEN S. 



" In August 1830 Mr. M'Nab of the Edinburgh Botanic 

 Garden found at the base of the precipice (east side of Ben- 

 a-Buird) a tuft of S. ccespitosa, portions of which he gave to me, 

 as I was near when he happened to find it." " Macgillivray's 

 Nat. History of Deeside " (1855), p. 127. 



" Beinn-a-Bhuird consists of two tops, the north one being 

 3924 ft. (Aberdeen and Banff) ; and the south one 3860 ft. 

 (Aberdeen). They are i^ miles apart." 



94. BANFF. 



Formerly referred to Aberdeen, but correspondence with 

 Mr. F. Webb and Mr. H. C. Watson caused Mr. Watson to 

 refer it to Banff. The specimens were collected on 3rd 

 August 1830, on Ben Avon, by Dr. Martin Barry, and I 

 possess two of the specimens then gathered. They are 

 most certainly the true arctic plant of Greenland !, Iceland !, 

 and Lapland. 



The group of mountains called Ben Avon comprises four 

 heads in Banff (3075 to 3554 ft.), and two in Aberdeen and 

 Banff (3625 and 3662 ft.), Ben Avon itself being 3843 ft. 

 in altitude (Munro, I.e.}.
