some hills in Bory Valley, which «-ere only 75—100 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: Aim 

 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.
