to /. patens. It differs, however, by the outermost branches 

 forming rather dense corymb dusters, whose secondary bran- 

 ches are short and somewhat robust, hooked backwards or 

 angular, closely compact and often connected with one ano- 

 ther by peculiar fastening organs. I suppose it to be the 

 same form mentioned by Kjellman from Nordland in N. Ish. 

 A-lgfl- p. 153, and besides that it has also been found at 

 Haugesund. At East- Finmarken it occurredon an ironbuoy, 

 which had been laid out in August, 1885, and was put on 

 shore for cleaning in the summer 1887. The specimens had 

 a length of 9 — 14 cm. and were richly sporocarp-bearing in 

 the middle of July. Some of them are more nearly related 

 , to a distans than to p fasciculata. On the other liand, this 

 . lorm reminds of f, typica and sometimes approaches it nearly 

 by its branches being more or less erect. ' 



The other forms above citied also occur at Finmarken, 

 but by no means distinctly marked out. I have certainly 

 ^et with specimens which almost fuUy coincide with Toly- 

 ^iphonia patens Aresch. Alg. Scand. exsicc. Ser. 1, No. 58, 

 "which, according to J. G. Agardh is identic with f. formosa, 

 hut I consider merely an intermediate form betweenf. typica 

 tod f. formosa^ resembling the former by its more or less 

 erect (or sometimes patent, not recurvated) branches, and the 

 latter by its ilaccidity. The most characteristic of these 

 forms at East-Finmarken is f, roscola, which, however, is 

 ^ore densely branched, somewhat coarser, more flaccid and 

 the lateral branches more erect than the above quoted spe- 

 cimens distributed by Ar eschoug andWyatt. It closely re- 

 sembles the habit-figure inHarvey's Phyc. Brit, t. 168. I 

 bave referred to f. comosa some specimens, which resemble 

 f- roseola except that they are rather rigid and straight in 

 tte lower part of the frond. The forms are very variable 

 ^ith reference to the length of the cells. 



The present species is litoral as well as sublitoral. Best
