The place looks rather bright coloured, thanks to the last three lichens. 



I have also visited the south part of Mt Duse. The slopes towards SW and S 

 are mere piles of stones, with single phanerogams and patches of Audreaea-tundra.. 

 On the top (495 m) I only found poorly developed specimens of: 



Andreaea viridis Neuropogo7i melaxantkum 



Dicranoweisia subinclinata Rhizocarpon geographicurn. 



The mountain (about 200 m?) on the south side of Pot Harbour. 

 Moss and lichen tundra with but few higher plants (Accena tenera, Aira antarc- 

 tica, Festuca erecta, Phleufn alpinum, Polystichum molirioides v. plicatum).

Junction valley. 



The lower parts of this valley are clothed with a grassy tundra, which is soon 

 split up into patches and disappear before the pass (350 m) is reached. There I 

 observed only crustaceous lichens. The NE. slope of the valley has a very desolate 

 aspect — nothing but piles of stones and large snowdrifts. Neither mosses nor 

 fruticulose lichens were seen. The opposite side, as might be expected, is rather 

 different. The ground was comparatively free from snow. 



Between the large heaps of debris, especially on sheltered places there occur 

 small colonies of an Andreaca-tundra, now and then with higher plants. Thus, at 

 about 375, I found a small mat of Acaena adscendens with Aira antarctica and 

 of course accompanied by a species of Tortula. At 400 m I still found Acaena 

 tenera, Aira antarctica, Colobanthus crassi/olius, Festuca erecta and Pldeum al- 

 pinum, and just below the top of the ridge, at a height of 490 m, I found Acaena 

 tenera, Aira antarctica and Phleum alpinum. This is, I should guess, the highest 

 station in South Georgia where flowering plants are recorded from, but I suppose 

 that we have not reached their upper limit with this. I cannot see why they should
