colour is yellowish brown by dried specimens. Thus in out- 

 ward appearance they agree fuUy with young plants of PA. 

 lorea as described by Kjel lm an 1. c. But they are, as 

 far as I am able to jndge, young plants of the above mén- 

 tioned f. lanceolata.

The form lanceolata is the most commonone, and young 

 as well as elder specimens occur plentifully on mnch exposed 

 places along the open coast of East-Finmarken, for inst. Om- 

 gang, Havningberg, Vardo and Kiberg. 



The other form, which I call f. ohlonga, has an oblong, 

 oblong-lanceolate or ovate-lanceolate larnina, cryptostoraata 

 commonly fewer and the colour a little darker than by the 

 preceding one, especially the stipe and the lower part of the 

 lamina. The stipe is more or less distinctly marked from 

 the lamina. The following measures show the proportions 

 by young and elder specimens.
