4. Torekov ('/is 17). Fig. 1 is a profile of this locality. The substratum is 

 solid rock, much fissured on the surface and in a state of progressive disintegration 

 by weathering. In the epilittoral belt a shallow layer of soil covers the rock, in 

 the belts close to the sea cracks and fissures in the rock are the only places where 

 vegetation can gain a foothold. There is an almost continuous turf of Festuca 

 rubra and various mosses in the transition zone between the upper supralittoral 

 and the epilittoral belts. The transitionzone passes into a talus formation composed 

 of detached, angular pieces of rock that have accumulated at the base of the 

 gently sloping rock. Some of the I'ocks are so large as to remain stationary, and 

 the talus is on the whole quite stable. A migration of plants into the talus takes 

 place both from the transition zone and from the above lying epilittoral belt. As 

 to the lichen growth, the lower supralittoral belt is black with Verrucaria maura,
