for this species outside of Bering 1 Sea, the plants are all young 

 and do not show the characteristic rhizomes, and may be forms of 

 L. Bongardiana or L. bullata.

A plentiful and very well marked plant when fresh, but not 

 always so characteristic in herbarium specimens. No. 343 of 

 Tildcn's American Alga? seems to have a broad midrib similar to 

 that of Pleurophycus instead of the usual triple fold, but this 

 may be the result of too much pressure. When young or pressed 

 too much, some plauts may readily be taken for forms of Lamina- 

 ria solidungula. So far as we know, the fruit of this species 

 has never been described. No. 5177 shows an extended sorus at 

 the base of the plant, but confined to one surface.

Tin- present very interesting and distinct genus of kelps has 

 been well described by Saunders (loc. cit. ) and by Setchell (1901, 

 p. 123), and distributed by Miss Tilden as noted above.
