Marine Algce of Bemvick-ou-Tiveed. 301 



fronds are usually nearly smooth with sometimes a row of 

 shallow depressions running along the centre. The fructification, 

 moreover, forms a distinct continuous band, not interrupted l>y 

 the bullations, down the centre of the frond, the blotched 

 appearance so marked a characteristic of the northern form being 

 quite wanting. This northern plant seems to me to be J. G. 

 Agardh's Laminaria hieroglyphica.

 Fronds long, thin, very narrow, the margins wavy, stem very 

 short, base of the lamina fusiform. 

 By far the most marked of the varieties of Laminaria saccharina 

 which occur on our coast. The fronds are very thin, of a 

 pleasant yellow-brown colour, changing to green in drying. 

 The plant usually grows where there is a constant stream of 

 salt water running between rocks, and in all probability most of 

 its variations from the typical form may be accounted for by 

 this circumstance. Foslie * says that all the Norwegian specimens 

 which he has seen bearing this name in various herbaria, should, 

 so far as he was in a position to judge, be referred either to 

 young specimens of Agardh's variety membranacea, or to the 

 variety longissima (Gunn.) Foslie.
