THE VEGETATION IN SOUTH GEORGIA.

not occur on any place free from ice and snow, where there is any soil, at a height 

 of i ooo m or more. But another question is if there is such a place on the island; 

 probably everywhere the conditions above 500 m are but little favourable to plant life. 

 The moss and lichen tundra is composed as follows: 



Andrea ta heterophylla 

 squamata 

 Willii 

 Bartramia patens f. austrogeorgica 

 oreadella v. microphylla 

 pycnocolca 

 Bracliythecium georgico-glareosum 

 Dieranoiveisia brevipes 



Dicranum aciphyllum f. 



Grimmia eelata 

 s grisea 



Rhacomitrium nigritum 



Webera inflexa 



Cladonia pyxidata 

 Peltigera rufescens. 



On the rocks- and stones : 



Aspicilia pullata 

 Buellia melanotrich ia 

 Lecanora Skottsbergii 

 Lee idea elaeochroma 



Leeidea pantherina 

 platycarpa 

 » subdeclinans 

 Rhizoearpon geographieum. 



All these species were in fruit. 



Mount Krokisius (Royal Bay). 



The general distribution of plant associations on this mountain are the same as 

 described from several localities in Cumberland Bay, though the areas covered with 

 close communities are smaller. On the top (c. 500 m) I found no higher plant, but 

 only mosses and lichens. 



Andreaea Willii Tortula fuscoviridis 



Dieranoiveisia subinclinata 



Dicranum aciphyllum Psoroma hypnorum 



Grimmia umulacea SpJiaerophoron coralloides 



Sticta Freycinetii. 



On stones: 



Neuropogon melaxanthum 



Ochrolechia parella 



all in fruit. 



Rliizoearpon geographieum 

 Sporastatia testudinea, 



The alpine tundra may be found developed at a much lower altitude, if the 

 conditions are unfavourable for vascular plants. On plateaus, exposed to the full force 

 of South Georgian gales, mosses and lichens always predominate. I noted this on
