extended distribution seem to indicate that it is a primitive form, and 

 more nearly related to the primitive ancestor of the Laminariece than 

 any other known form except Chorda. Chorda, however, needs to 

 be studied more carefully in order to determine its relationships more 

 clearly. 



Literature. 



Below are given as many of the references to Saccorhiza dermalodea 

 as have come to the knowledge of the author : — 



Laminaria dermalodea., De la Pyl., Ann. Sci. Nat., Ser. 1, Tom. 

 IV. pp. 179, 180, PI. IX. Fig. G, 1824.

 1829.

* Areschoug referred this name as a synonym under his Laminaria lorea, No. 

 213 of liis "Algae Scandinavicse Exsiccatae," by virtue of a specimen received 

 from Iluprecht. He makes a furtlier reference to it in the "Observationes 

 Phycologicae, Particula Tertia" (p. 12). Gobi places it under his Phijllaria 

 dermalodea in "Die Algen Flora des Weissen Meeres " (p. 75), giving Rosta- 

 finski as his authority for doing so. Kjellman refers to Gobi as his authoritj' 

 for quoting this name as a synonym under the Phyllaria dermalodea of his 

 "Algae of the Arctic Sea" (pp. 223 and 225). 



t Le Jolis in Examen II. puts under Haligenia (Phyllaria) dermalodea, "nee 

 Rupr.," referring probably to this reference. 



t Agardh quotes the Laminaria Bongardiana, Post. & Rupr., as a synonym of 

 Laminaria dermalodea, De la P.vf, in the " Species Algarum," and has thus given 

 grounds for the assertion (cf. Le Jolis, Examen I., p. 583) that the L. dermalodea 

 of the " Species " was not the true L. dermalodea, De la Pyl. Agardh, however, 

 in "De Laminarieis" (p. 83) explains how it was that lie came to quote L. Bon- 

 gardiana as a synonym of L. dermalodea, but asserts that nevertheless his 

 reference really includes the true L. dermalodea, De la Pyl. 



§ Harvey does not quote L. Bongardiana, Post. & Rupr., as a synonym; but 

 his description of the old plants (for he says that he had seen only young 

 specimens) was evidently taken from Agardh, and refers to some form of the 

 true digitate Laminarioe.
