356 NOTES ON THE DISTRIBUTION OF 
remains for any great length of time (excepting in winters of 
unusual severity) over a belt parallel to the sea, and extend- 
ing a few (probably 6 to 10 miles) inland. 
Like the former communication, this can only be con- 
sidered supplementary to Mr. Watson’s second paper in 
the 6th number of this Journal, and the same order will be 
followed : 
Cerastium latifolium. A plant agreeing with the descrip- 
tion in the British Flora occurs abundantly on the hill of 
Khoil (composed of serpentine) near Ballater, the lowest 
limit being 1742 feet, and 43 miles inland. 
Even supposing it to be the other species, C. alpinum, 
this locality will be lower than the lowest recorded by Mr. 
Watson. ; 
Statice Armeria. Is found along the whole course of the 
Dee from above Ballater to Aberdeen, Silene maritima being 
sometimes associated with it; and both may be seen with 
C. latifolium in the locality already mentioned. 
It is perhaps worthy of remark, that in the interior of 
Aberdeenshire, the S. Ærmeria is most usually found on 
serpentine, as at the place already alluded to; it also occurs 
on the Green Hill of Strathdon, composed of the same 
rock (43 miles inland, and at about 1500 feet), and on the 
serpentine in the vicinity of Rhymie, estimated as not ex- 
ceeding 600 feet above the sea, and 33 miles inland. In 
Strathdon and near Rhymie, this plant is associated with 
Arenaria verna, which in this county has hitherto only 
been found on serpentine; the upper and lower limits of 
A. verna being therefore 1500 and 600 feet. 
Salix reticulata. Rocks in Glen Callater at 2000 feet, 
about 60 miles from the sea. 
Veronica alpina. Glen Callater, 2300 feet. 
Juncus castaneus. Glen Callater, 2300 feet, but rare. 
Saussurea alpina. Glen Callater, 2245 feet. 
Arabis petrea. On the gravelly banks of the Dee at 
Ballater at 800 feet (49 miles inland). It also occurs on 
the Khoil with C, latifolium, Silene maritima and Statice
