size, associated with Drosera anglica, D. rotundifolia, Schenus 
nigricans, Lycopodium selaginoides and others. I have also seen 
it of very small size in the vicinity of Ballater, forty-two miles 
inland, and about 900 feet above the sea-level, where it was dis- 
covered by Mrs. Mackay. 8S. mmnioides and S. sphericum are 
found upon the hill of Fare, thirteen miles west from Aberdeen ; 
the former is the rarer of the two in that locality, but occurs 
lowest, viz. at 450 feet of elevation ; the other is abundant near 
the top of the hill at 1000 feet, growing in moist places upon 
droppings of cattle. In the same locality, my friend Mr. James 
Barron found the carcase of a grouse completely incrusted with 
very large specimens. The most elevated point at which I have 
seen S. sphericum in this county is on the highest table-land 
above Glen Callater. S. mnioides grows on the summit of Loch- 
nagar at 3800 feet, where I have found it in tufts, each inclo- 
sing a fragment of bone. The same species occurs in great pro- 
fusion in the different glens leading to the base of Ben-na-Muich- 
Dhu, the ground being literally sprinkled over with large tufts 
of it; the red-deer are numerous in these glens, and the species 
in question finds a suitable soil on their droppings. S. tenue 
appears to be rare in this county ; I have seen it in Glen Callater 
in small quantity, and at an elevation of about 1600 feet. The 
range of S. angustatum has not been very accurately ascertained, 
being probably from 2000 to 3000 feet; nor that of S. vasculo- 
sum, which may however be about the same. I have searched 
in yain for S. Frelichianum, mentioned in the ‘ British Flora’ on 
the authority of Mr. Dickson as growing on Bennachie, or Ben- 
High as it is sometimes called. This hill is about twenty miles 
west from Aberdeen, rising rather_abruptly from the surround- 
ing country, and attaining 1700 feet of elevation.

The first three only of these (keeping out of view S. Frelichianum) 
occur within the limits of cultivation ; the second exceeds all the 
others in altitudinal range. 
Conostomum boreale. Ihave never seen it under 2000 feet ; 
it attains the summit of Lochnagar (8800), which however is 
probably not its upper limit. Mr. Edmondstone informed me 
that in Shetland it grows near the sea with Grimmia maritima.
