 others. 



Kjellman mentions Crossocarpus lamuticus Rupr. in Ora 

 Beringhafvets Algflora, p. 30. The specimen is kept in the Bo- 

 tanical Museum of Upsala. It is a sterile and small specimen, 

 quite resembling to the form shown by Ruprecht as PI. 14, fig. c 

 of the above cited work. In its substance and general appearance 

 I have a strong doubt on its determination if it might be more 

 safely taken as a young form of the present species. 



In the Agardhian Herbarium, any specimen of either Kally- 

 menia Gmelini Grun. or Rhodywenia Gwelini Grun. could not 

 be found by myself. J. Agardh mentions its tetraspores to 

 occur among the cortical cells and cystocarps in small dots re- 

 sembling to those of Iridaea. Grunow's originals in Berlin, as 

 far as I could understand, are sterile and the author gives no 

 account on the fructification of his plant. I am, therefore, in- 

 clined to reserve the observation by J. Agardh as a question 

 until we could obtain more specimens of the fruit-bearing plants. 

 In the Herbarium, some of the specimens of K. rosacea J. Ag., 

 especially those from Spitzbergen, appeared to me to be com- 

 parable with Kjellman's specimen of Crossocarpus lamuticus 

 at Upsala, and consequently with the present. Schmitz X) has 

 ever referred K. rosacea J. Ag. to Turnerella. This is, however, 

 perhaps by some misunderstanding. 



Finally, a specimen is distributed as Phyc. Bor.-Amer. No. 

 934 under Rhodywenia palmata f. mollis Setch. et Gardn. On 

 the label attached to the specimen, the authors note:— "They 

 seem to be in many ways Ruprecht's Crossocarpus lamuticus, 

 and it was the intention of the distributors to place them under 

 the latter specific name. Prof. Kjellman, however, has ex- 

 amined some of the material, and has decided that it is not 

 identical with Ruprecht's species. Consequent!}- it is distri- 

 buted under the provisional name given above." I have seen a 

 specimen of it in a herbarium in Europe but tried no microscopical 

 examination on it. It appeared to me that Kjellman's sugges-
