regions of Southern Europe ascending to the summit of the Pyrenees, and to the level of perpetual snow on 
the Alps. Again, in the Arctic zone it is found carpeting the otherwise naked steppes of Asia and the barren 
lands of America, thence reaching the ultima thule of vegetable life in Melville Island and Ross Islet. To the 
south of its principal parallel it inhabits the Canary Islands, and a variety is seen on the Andes of Mexico and 
Colombia. Still further south it is replaced in all longitudes by the following species, being itself unknown 
in the Southern Hemisphere except at Cape Horn and Kerguelen’s Land, where it re-appears in abundance. To 
reconcile this singular fact with the views of those who suppose it to have migrated into Kerguelen’s Land, it is 
almost necessary to consider the S. ramulosum, which inhabits Lord Auckland's group, Campbell’s Island, Tasmania, 
and the northern parts of Fuegia, as a southern variety of S. corallinum, which has, in Kerguelen’s Land and Cape 
Horn, reverted to the northern form.

This widely distributed species replaces in the Southern Hemisphere, to a considerable degree, the S. paschale 
and corallinum of the Northern, but not fully; for it only enters what we have elsewhere defined to be the Antarctic 
zone of vegetation, not reaching the Falkland Islands, the southern parts of the Fuegian Islands or Kerguelen’s 
Land. In the Old World it first appears in Bourbon, thence ranging from the Philippines, through Java, Australia, 
the South Sea Islands, Tasmania and New Zealand, to Lord Auckland’s group and Campbell’s Island, abounding 
in rocky and damp places, also on the trunks of large trees. In the New World it commences in the West Indian 
Islands, whence Swartz originally procured it, and runs through every parallel of latitude to the Strait of Magalhaens. 
As a species S. ramulosum appears, at first sight, abundantly distinct from 5. corallinum, nor does it display a 
tendency to assume any northern form of the genus in the Strait of Magalhaens. In Tasmania, again, where it 
ascends the mountains and becomes dwarfish, its lateral ramuli are still slender and fibrous, typical of the 
species. On the other hand, some of the tropical specimens, especially those from the Equatorial Andes (where 
both species occur), appear intermediate between S. ramulosum and corallinum ; insomuch that it becomes a matter 
of opinion alone, whether the 8. ramulosum should be considered a southern state of $. corallinum, owing its greater 
development to the more uniform temperature and humidity of the localities it affects in the Southern Hemisphere ; 
or whether these are two species, one originating in the Southern Hemisphere, and one in the Northern, meeting 
under the Line, and there varying into the similitude of one another.
