As stated in Lam. Norvv. 1. c, a form of this species 

 occurs at East-Finmarken, wliich, as far as I am able to 

 judge, must be referred to L, Agardliii Kjell m., common 



r 



at the coasts of Spitzbergen, Novaya Zemlya and probably 

 also in the White Sea. It is on the other hand so nearly 

 related to certain forms of L, saccliarina^ that I am unable 



■ L 



to draw any limit. According to K j e 11 m a n it is different 

 frbm that species mainly by the wantingof muciferouslacunæ. 

 The lacunæ are in general pretty common in the laminafey 

 Scandinavian specimens oiL, saccliarina, sometimes very large, 

 sometimes small, but not seldom qnite wanting. As far as 

 I tave seeni, it depends on the localities and conditioiJå where 

 the plant grows. Cp. Fos 1. 1. c. p. 94.
