M. Foslie. 



] amina is ovate-lanceolate, 40 era. long and 8 cm. broad in 

 the broadest part (dried spee), witli roiinded and a little 

 decurrent base. 



The species in question appears on open and exposed 

 coasts as well as in more sheltered localitieSj and it even 

 enters pretty far into the deeper bays. 



Distribiition: Coramon and plentiful all alongthe coast.

I think this species to be so nearly related to the fol- 

 lowing one, that any limit hardly may be drawn between 

 them. It is no doubt the most comraon Alaria along the 

 unsheltered part of the coast. It is here vigorous and very 

 luxuriant, reaching considerable dimensions. I shall give the 

 measurments of some of the largest specimens I coUected.

A young specimen collected together witk the above 

 mentioned ones has a remarkably narrow lamina, reminding 

 of A. Unearis S tro mf. The stipe of it is 8.5 cm. long and 

 bears a few very young (1 — 5 mm. long) sporophylls. The 

 lamina is lanceolate-linear, 115 cm. long and 4.3 cm. broad

in the broadest part (dried spee.) with angustated base. 



On an iron buoy atBerlevaag, laid out in July — August 

 1885, and put on shore for cleaning in July 1887, I found 

 a smaller specimen, the stem of which had a thickness of 

 nearly 1 cm., showing in a transverse section two concentriG 

 rings. One oi these rings^ the outer, is somewhat indi3ti|ict.
