some hills in Bory Valley, which were only 75—-I0o0 m high, but rose out of the 
tundra-meadows as isolated habitats for a tundra of an alpine type. On the top of 
these hills there were scattered phanerogams of a very stunted appearance: Azra 
antarctica, Festuca erecta, Phleum alpinum and Poa flabellata, the ground being 
covered with mosses.

It is not easy to establish different vertical regions in South Georgia. The 
limit of importance is the upper boundary of tundra-meadow, but this is met with 
at very variable heights, according to steepness, extension of debris, exposure et c:a. 
We find it at 50 or 150—200 m, all according to the circumstances. No higher 
plant is known, which has a true alpine distribution. Two, perhaps, prefer more 
elevated situations, Acaena tenera and Polystichum mohrioides v. plicatum, for they 
are more frequent there, and on the mountains round Lago Fagnano in Tierra del 
Fuego both of them belong to the alp-plants. But there we have a forest-belt and 
a tree-less, alpine region. In South Georgia there is no reason why the alpine plants 
should not reach down to the sea-level. It must be noted, however, that, as far as 
we know now, several mosses are only found high up on the crests and ridges.
