of Up.sala under Alaria sp ?, undoubtedly the plant mentioned in 

 Beringhafv., p. 42, appears to me to be a fragment of an abnormal 

 blade of A. fisMosa, although the characteristic lioUow midrib could 

 not be ascertained in the spechnen. 



In Illustr. Alg., p. 11, Postels and RurRECHT mention A. 

 marginata ß miisœformis. Tlie brief description of this forma does 

 not give any concrete idea of a distinct form of the plant. The 

 original, kept in the herbarium of the Academy of Science of 

 Petrograd, is a poor specimen without sporophylls. Setchell^) 

 notes that he recognized in the midrib an " evident symptom of 

 having been characteristically and interruptedly fistulöse." 



Kjellman^) remarks on the present species : " Arten synes 

 mig vera närmost beslägtad med A. tœniata. Kostans grundform 

 är densamma." I am rather astonislied to read tliis statement.' 

 In the herbarium of the Botanical Museum of Upsala there is a 

 young specimen of A. crassifolia Kjellm. determined by Kjellman 

 as A. fistulosa. The above statement together with this identifica- 

 tion make me doubt the specific conception of A. fistulosa held by 



K.TELLMAN. 



In the remark appendiced to tlie note on Orgijia phinata, Gobi 

 mentions a specimen with hollow and septated midrib in the Her- 

 barium of the Botanical Museum of the University of Petrograd. 

 The specimen, according to him, is from Postels and has been 

 collected in a northern sea without exact locality. I have not 

 seen tlie specimen in the Herbarium. But it appears to me very 

 likely that it might have been collected in the North Pacific and 

 should be identified with A. fistulosa. Gobi was tempted to neglect 

 the peculiarity of the midrib, saying : — " Ich führe dieses Beispiel
