The coralline mofies are fubjed to great variation z. 
and altho’ there are feveral really diftind fpecies, yet 
they ran fo into one another, that it is no eafy mat- 
ter to fix upon the real fpecific diftindions, in many 
infiances. Some fpecies are perfedly white ; others 
have the extremities of the branches reddifh, fome 
brown, and others almoft black. The common co- 
ralline mofs in Lapland not unfrequently grows to be 
feveral inches long, and even a foot high. 
The tubular or hollow branched coralline mofie3 
are not the only kinds upon which the rein-deer will 
feed. Almoft all the lichens are abundantly more 
plentiful in thofe northern, than in thefe more fouth- 
erly climates. There are feveral fpecies with folid 
branches ; one, which Dillenius calls ' The crifp warty 
Alpine coral loides (4), which is almoft as plentiful 
as the common fort, and is equally acceptable to 
thofe animals (5). It was before obferved, that, in 
defed of thefe mofies, the black mane ufnea is a fub- 
ftitute equally acceptable to thofe animals. 
Another of the moft remarkable and ufeful plants 
of this divifion is the orchel (6), or argol , as it is

not common in England. Dr. Dillenius found it upon fome of 
the mountains in Wales. It is found in many places on Charley- 
foreft, Leicefterfhire.
