Prof. Eaton has kindly sent me a copy of Areschoug's 

 description (in Botaniska Notiser for May 15, 1876), 

 of what he, with some hesitation, names a new species : 

 N. gigantea, which answers very well to Mr. Cleveland's 

 plant. It would seem to be an easy matter for our 

 California botanists to settle the question of whether 

 or not these two extreme forms are always distinct, 

 or insensibly pass into each other, in a large group 

 of specimens ; or whether the iirst is but the 

 young of which the last is the mature form, as some 

 botanists seem to think. Mr. Cleveland assures me 

 that the last described form is quite constant. 



It is a very common plant, growing in deep water, 

 all along the west coast, at all seasons, and is flung 

 on shore in great quantities by the storms.
