358 NOTES ON THR DISTRIBUTION, &c. 
Saxifraga aizoides. Not unfrequent along the whole 
course of the Dee to Aberdeen. The lowest natural limit 
appears, however, to be in the parish of Lumphanan at 
Findrae (in wet places), 20 miles inland and probably not 
exceeding 500 feet above the sea level. 
Arbutus Uva Ursi. In great profusion on a moor, 12 
miles west from Aberdeen, at about 300 feet. 
Galium boreale. Very abundant near Aberdeen, and not 
uncommon along the whole course of the Dee. 
Carex pauciflora. Very abundant on the hill of Fane, 15 
miles west from Aberdeen, at 800 feet. 
I embrace this opportunity of recording the elevations of 
two of our rare plants, viz. Carex rupestris and C. leporina. 
C. rupestris. Glen Callater, not lower than 2000 feet, 
plentiful at 2397 feet, but I was unable to measure its 
highest point. Last summer Professor Balfour gathered it, 
along with Zuzula arcuata, and Astragalus alpinus, on the 
Ben Avon range, the altitude is not, however, recorded. 
This will be alower limit for the L. arcuatain this part of the 
country, than has hitherto been found, since the Ben Avon 
range does not exceed 3920 feet. 
C. leporina. On Lochnagar at 3559 feet more or less. 
The best guide to its locality is the Glassilt burn, which falls 
into Loch Muich, near its head and on its north bank. 
It will be found ina line, leading directly from the source 
of the Glassilt; it grows on the slope overlooking the 
Loch-an-yeans, (Birds! lakes). It occurs among the de- 
bris of rocks, moistened by springs; there is usually some 
snow in its vicinity, often partially concealing it; Poa al- 
pina, Phleum alpinum, and Alopecurus alpinus, are found 
with it. 
The Birds’ lakes are on the west side of Lochnagar, and 
at the foot of the White Mouth, a high peak near Loch- 
nagar.
