The species is also along the coast of the northern Nor- 

 way somewhat variable with reference to the habit, and, 

 moreover, it here often becomes coarser and more rigid than 

 more sonth. Thus the Finmarkian specimens of f. typica are 

 usually rather coarser and more robust than for inst. Swe- 

 dish and English ones. Cp. Aresch., Alg. Scand. exsice.

The form named by me f. patens ^ fasciculata is coarser 

 and still more rigid than any form of f. typica, and the se- 

 condary branches are remarkably squarrose or recurvated, in 

 which respects it is, as far as I can judge, nearly related
