Explanatory notes to some of the plates. 



Plate II. Here the distribution of Poa flabellata on the slope of Mt Duse near May 

 Cove is clearly shown. Near the sea it forms a continuous cover, then getting more split 

 up into patches; their dark colour on the photo contrasts well with the masses of debris 

 between and round them. Below is the typical tundra-meadow of Festuca erecta. 



Plate III. Illustrates the best growth-place for Poa, a beach of shingles. Some 

 tussocks plainly show the basal part of the plant covered by dry, yellow blades, which also 

 form the soft bed in the winding paths between the tussocks, the favourite resting-place of 

 the sea-elephant. The hills in the background are clothed with the same plant. 



Plate IV. An old and large specimen of Poa flabellata, of typical growth, from 

 near the beach. The stick is 150 cm high. 



Plate V. 1. A. general view of a part of "the plain". The distribution of the 

 tussockgrass is seen, as well as the dark brown Pofytric/ium-tundra.. The rock in the fore- 

 ground is one of the places where the petrophilous association was studied. Along the 

 edge of the Penguin Stream a swampy tundra. The water is the Moraine Fjord. 2. Tundra- 

 meadow in winter. The grass is Festuca erecta; besides numerous dry fruit-heads of 

 Acaena adscendens. 



Note. Ail the photographs were taken in May — June. i. e. at the beginning of the winter.
