 on open coasts as well as sheltered ones, and it att ai ns a 

 length of nntil 25 cm. Zoospore-bearing specimens have 

 been coUected in July and August.

This is probably the most common Monostroma along 

 the coast of East-Finmarken. It appears to be a well dif- 

 ferentiated but much varying species. The plant has when 

 yonng frequently the form of a pear-shaped bladder but is 

 sometimes also cylindrical. A specimen in my collections 

 has the fonn of a cylindrical sack, 8 cm. long and 1,5 cm. 

 in diameter. Another is 18 cm. long and 3 cm. -in diame- 

 ter iipwards, and open at the top. When it in its further 

 growth børsts down to the base and expandsmcmbraneonsly, 

 it often does not become laciniate but continues simple with, 

 in general, slashed margin. -A specimen is 18 cm. lon^ and 

 18 cm. broad with deep reniform base, Another is 

 long and 14 cm. broad with cordate base, Others have a 

 broad, cuneate base. But, on the other hand, the frond is 

 sometimes split ,up even to the base in bro^^deror narrower 



r 



segments, depending on the place of growth. When small, 

 -sach specimens much remind of certain f orms oi M. arcticiim. 



The ■present species is litoral, growing on rocks, in 

 rock-pools and attached to shells af Balanidæ or to other 

 algæ, as Fitci, Balosaccion ramentaceumy Qigartina mamillosa
