Bd. IV: ı2) THE VEGETATION IN SOUTH GEORGIA. 23 
Rosita Harbour (Bay of Isles): 
Bryum lamprocarpum Pottia austrogeorgica var. 
Dicranoweisia grimmiacea microphylla n. v. 
> subinclinata 
Grimmia hyalinocuspidata var. 
mutica n. var. Chiloscyphus köppensis 
Hypnum uncinatum f. Lophocolea otiphylla 
Orthotrichum crassifolium > secundifolia. 
The special cliff moss is evidently Orthotrichum crassifolium, recorded from all 
localities except one, but never found in another situation. 
The stones are more or less covered with lichens, of which the following are 
important: 
Acarospora molybdina Physcia caesia 
Buellia sp. Placodium lucens 
Lecidea auriculata » millegr anum 
Leptogium tremelloides > miniatum 
Mastodia tessellata » murorum. 
Verrucaria sp. 
Of these, the P/acodia are of a certain importance for the landscape because 
of their intense yellow or red colour. 
3. The inland tundra. 
According to different exposure and different mechanical composition of the 
substrata there are all transitions between a tundra rich in grasses and the moss- 
and lichen carpet, where phanerogams are of small or almost no importance. The 
former type was once called by me meadow (2b), a name perhaps not suitable in 
this case. 
Jason Harbour. The lowest, rather steep part of a slope at the west side of 
the cove shows the following vegetation: 
soc. Acaena adscendens sometimes forming pure mats. 
cop. Galium antarcticum, with the former. 
sol. Arra antarctica Phleum alpinum 
Festuca erecta Ranunculus biternatus 
Juncus scheuchzerioides Rostkovia magellanica.
