of A. cscuJerda f. musœfolia Kjellm., Alg^e Arctic Sea, p. 212, is 

 a typical form of A. escidenta Geev. He also mentions the species 

 in the h'st of alga3 from Nova Zembla. Cfr. Algenveg. Murman. 

 Meeres, p. 35. He regarded it as a northern form of A. escu/enta 

 (Algœ Arctic Sea, p. 213). 



I am inclined to suj^pose that De la Pyl meant by Lammaria 

 musœfolia those individuals of AI aria which have the blades trans- 

 versely cleft so as to resemble a Musa leaf, and by Laminaria 

 esculenta var. platyphyUa those which have blades still young and 

 plain, without placing much importance on the other characters.

This species has been established on the material brought to 

 Europe by Delise from Newfoundland. I did not see any authen- 

 tic specimen. .Rupeecht doubts the species, thinking it referrable 

 to Laminaria esculenta var. remoti/olia De la Pyl. Cfr. Tange des 

 ochotischen Meeres, p. 364.
