300 Dr. G. Dickie on the Altitudinal Range 



Penzance ; Truro, by Miss Warren ; Bristol, by Mr. Thwaites ; 

 Sussex, by Mr. Jenner, and Hitcbin : 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 vrhich they refer, and the general remarks 

 founded upon them must therefore be considered as mere ap- 

 proximations. 



Andrea. 



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. Andrcea rupestris and A. Rot Mi; 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. 



Andrsea alpina 1200 feet. 3800 feet (highest?) 



rupestris ... 80 8800 



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. 



(Edipodium Griffithianum. 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 j 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 altitu.dinal 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.
