300 — Dr. G. Dickie on the Altitudinal Range 
Penzance ; Truro, by Miss Warren; Bristol, by Mr. Thwaites ; 
Sussex, by Mr. Jenner, and Hitchin: I also consulted a list of 
Mosses found in Devonshire by Dr. Greville, and published many 
years since in the ‘Transactions of the Wernerian Society,’ one 
on the Mosses of Teesdale by Mr. Spruce, and Dr. Greville’s 
‘Edinburgh Flora’; Mr. Edmondstone also furnished notes on 
those found in Shetland. Those interested in this subject may 
consult a list of Mosses found in one of the Western Isles by 
Dr. Balfour, and published in the ‘ Transactions of the Edinburgh 
Botanical Society.’ Several of the catalogues alluded to evidently 
do not comprehend all the species that might be expected to grow 
in the localities to which they refer, and the general remarks 
founded upon them must_ therefore be considered as mere ap-~ 
proximations. 
ANDRA. 
All the British species of this genus are found in Aberdeen- 
shire ; two of them grow near the sea, and not 100 feet above its 
level, viz. Andrea rupestris and A. Rothii; they are also found 
inland and attain a considerable elevation ; A. alpina begins to 
appear in the vicinity of Ballater, forty-two miles inland, at an 
elevation of about 1200 feet ; A. nivalis is confined to the highest 
summits. 
Lowest. Highest. 
Andreea alpina......... 1200 feet. 3800 feet (highest ?) 
rupestris os. 80 3800 
—— Rothii......... 80 3400 
—— nivalis ...... 4000 and upwards. 
The first three of these are found within the limits of cultiva- 
tion: A. Rothii has an extensive latitudinal range, since it is 
recorded in the list of Devonshire species already alluded to ; 
A. rupestris is more limited; A. alpina first appears about the 
upper limit of cultivation. 
Cdipodium Grifithianum. This fine species seems to be mostly 
confined to the subalpine region *, occurring sparingly at 2000 
feet and usually barren ; I have seen it abundantly and with very 
fine fruit, near the summit of the highest table-land at the head 
of Glen Callater ; the height of this locality was not actually mea- 
sured, but was estimated as being about 3000 feet. 
Splachnum. All the British species occur in Aberdeenshire, 
some of them having a considerable altitudinal range. 
S. ampullaceum is the only one I have seen near the sea-level, 
where it grows in bogs upon droppings of cattle. Some years 
ago I found it near Aberdeen in great profusion and of large 
* The divisions into regions adopted here are those of Mr. H. C. Watson, 
and must be familiar to all who have studied the distribution of British 
plants.
