Harvey^) mentions Fucus jpl^^natus Fl. Norv. as a synonym 

 of A. esculenta Grey. The same view is adopted by the Scandi- 

 navian algologists SQch as Kjellman,^) Foslie,^) Börgesen,*) and 

 JÖNSSON.^) GfoBi^) also holds the same view but chose the name 

 Orgyla phmaia instead of A. esculenta Grey, on account of priority. 

 He further stated that some of the specimens which he calls 

 Orgyia pinnata seem to stand very near " f. memhranacea J. Ag."'^) 

 This resulted in an ambiguous disposition of Gobi's species in De 

 ToNi's Syll. Alg., Ill, p. 327, in which Orgyia pinnata Gobi is 

 found in a synonymous position under A. msmhranacea J. Ag. 



The views enumerated above are so widely divergent from each 

 other that I am unable even to model a general character of the 

 plant. I have not seen Gunner's type spacimon nor any co-type 

 of it. Gunner's original description and illustration can not help 

 us to catch the exact specific characters in the modern sense. 

 It is, liowever, almost beyond doubt that the plant wliich Gunner 

 has designated as Fucus plnnahus, occurring on the Norwegian 

 coasts, must have been A. esculenta Grey. 



Ruprecht seems to have believed that Fucus platycarpus Gmel., 

 illustrated in Hist. Fuc, PL XXXI, might have been a stipe of 

 A. esculenta or as he later calls it, Phas. alatum. But what Gmelin 

 has figured is undoubtedly a stipe of an old and decayed plant of 

 Thalassiophyllum clathrus. Specimens exactly agreeing with Gmelin's 

 figure may be found everywhere on the coasts of the northern

7) Gobi simply mentions this form-name ■without giving any hint as to which species this 

 forma should belong. So far I could refer to, such form-name has never been proposed by J. 

 Agabdh for either A. esculenta or .1. Pylaii.
