THE PLANTS OF THE GRAMPIANS. 245 
at a much lower elevation; the heights of those two hills 
being probably between 3,000 and 3,500 feet.) 
Sazifraga cernua. The lowest specimens that I saw upon 
Ben Lawers, were 250 feet below the summit, or at 3,750 feet 
above the sea. It is reported to grow on the neighbouring 
hill of Craigalleach, which cannot very much exceed 3,000 feet 
in absolute height. 
Draba rupestris. Observed at 3,700 feet on Ben Lawers. 
Dr. Graham reports that he gathered it on some neighbouring 
hill, where it is probably lower than on Ben Lawers. (It is 
also said to grow on Ben Hope, in Sutherland, a hill of only 
3,000. feet.) 
Lychnis alpina. The height of its locality, on the Clova. 
mountains, has been roughly guessed at 3,200 feet. 
. Cerastium latifolium. 1 observed this on rocks of 3,100 
feet on Ben Lawers. It is probably lower on Ben Lomond. 
Myosotis alpestris. At 3,100 feet, among the rocks, above 
the lake, on Ben Lawers. Perhaps at a lower elevation on 
other hills of the Breadalbane range. 
Juncus biglumis. In one place as low as 2,800 feet on the 
mountains between Ben Lawers and the Lochy ; though sel- 
dom seen much below 3,000. (If really found on Goat Fell, 
in Arran, a hill of 2,900 feet, we might a it even below 
2,800 feet, on the Grampians.) 
Statice Armeria. I have not eege this below 2,800 
feet on the Grampians, the height at which it was noticed 
near Killin, (It is a well-known sea-side plant; and in Cum- 
berland, I saw it on rocks at about 1,000 feet of elevation.) 
Saxifraga rivularis. A peculiarly alpine plant, though 
growing so low as 2,700 feet under the dark precipices of 
Ben Nevis, where it is kept cold and damp by the little rills 
trickling down from the melting snow above. 
Stellaria cerastoides. Also at 2,700 feet, in the same situ- 
ation, on Ben Nevis. Elsewhere I have not seen it so low 
as 3,000. 
Menziesia cerulea. Mr. Brand estimated the height of its 
locality, at 2,600 or 2,800 feet. 'The height of the hill on
