20 CARL SKOTTSBERG, (Schwed. Sudpolar-Exp. 



On the beach outside the tussock, scattered individuals of Deschampsia, Plilcum 

 and Festuca were met with. 



May Cove and north part of Bore Valley. 



The general distribution of the tussock has been described above; the carpet 

 extends back from the cove, covering the rounded hills but generally avoiding the 

 depressions between them. The finest individuals grows on the shingles and reach 

 a height of I — 1.5 m. (Plate 3, 4.) Acaena adscendens is abundant along the edge 

 and is accompanied by some species of Tortilla. On dead tussocks are extensive 

 patches of mosses and scattered individuals of Acaena tenera. 

 Brachythecium subpilosum Tortilla robusta 



Br yum lamprocarpüm Webern puhnnata 



Pogonatum alpinuni Cephalozia varions 



Polytrichum strictum Lepidozia chordulifera 



Tortula filaris Lophocolea kbppensis 



» monoica Lopltosia Floerkei. 



With Polytrichum was found Cladonia squamosa. 



On the shingles and stones near the water: Colobanthus crassifolius and subu- 

 latus, Bryum lamprocarpüm, Rhizocarpon geographicum. 



These examples may be found sufficient. I will only append a list of cryptogams, 

 noted by me together with Poa and Acaena in Royal Bay, from where WlLL de- 

 scribed the association in question:

Pogonatum alpinum f. 



Polytrichum strictum var. 



Tortula robusta Lophosia Floerkei. 



We have seen above, that peatforming mosses, such as Pogonatum alpinum and 

 Polytrichum strictum thrive well in the /W-association. Where a brook comes 

 down through it, the tussocks recede from the water, and mighty cushions of the 

 mosses close together and in parts encroach over the tussocks, so that a struggle 

 is going on between them. This we could observe round our camp in May Cove, 

 where the mosses, for reasons unknown to me, at present seem to be gaining ground. 

 The same thing was observed in Royal Bay, in both cases the peat-forming mosses 

 were Pogonatum alpinum typicum and f. austrogeorgicum and Polytrichum strictum 

 v. alpestre. Some lichens grow in the bogs, in Royal Bay I noted 

 Cladonia squamosa Ochrolechia tartarea 



Leptogium tremelloides Parmelia entcromorpha 



Sphaerophoron coralloides.
