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 Andreaea-tundra. 
On the top (495 m) I only found poorly developed specimens of: 
Andreaea viridis Neuropogon melaxanthum 
Dicranoweisia subinchnata Rhizocarpon geographicum. 
The mountain (about 200 m?) on the south side of Pot Harbour. 
Moss and lichen tundra with but few higher plants (Acena tenera, Aira antarc- 
tıca, Festuca erecta, Phleum alpinum, Polystichum mohrioides v. plicatum). 
Andreaea parallela Polytrichum piliferum 
Blindia capıllifolia Psilopilum antarcticum 
Ditrichum hyalinocuspidatum Rhacomitrium austrogeorgicum 
Conostomum australe » lanuginosum 
Grimmia occulta » ptychophyllum 
Lepyrodon lagurus » striatipilum 
Philonotis scabrifolia Pogonatum alpinum f. austrogeorgicum 
Parmelia enteromorpha Sticta Freycinetil 
Stereocaulon alpinum Verrucaria exquisita. 
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 Andreaea-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 crassifolius, Festuca erecta and Phleum 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
