Fig. 24. The Swedish distribution area of Vicia 



cassubica. 



O : uncertain or accidental occurrences. 



In Norway the species lias a few localities on the 



southern coast (Bainle, Lyngor — Christiansand); it 



is not found in Finland; in Denmark it occurs 



also in north-eastern Jutland, in Slesvig (Midsunde), 



on Fyen, and on Fjornholin. 



Fig. 25. The distribution of Hypericum montanum 



in Sweden (a West European species). 



O : imcertain occurrences. 



The species is pretty abundantly spread in southern 



and western Norway to Lofoten in the north; in 



Denmark it occurs rarely on the islands, except 



Falster and Lolland, and in Jutland; it is not 



found in Finland. 



A type which is divergent in several respects is represented by the continental 

 species Vicia cassubica (Fig. 24). 



In certain districts of the mainland of South Sweden this species is one of 

 the commonest in the flora that is especially distinctive of rock\^ escarpments 

 and dry wooded hills. 



The species has evidently a great capacity for spreading itself in limited areas. 

 It is probably spread by birds, e. g. gallinaceous birds, which gather the peas in 

 their crops. Conservator Kjell Kolthoff of Upsala has had the kindness to inform 

 me that one can imagine a very effective dispersal by the seizure of gallinaceous 

 birds with peas in their crops by birds of prc\', which like to seek out a place 

 from which they have a good \iew and where they can enjoy their booty 

 undisturbed, such as rocky cliffs and open wooded slopes. The content of the 

 crop will thus be emptied in such places.
