48 SEA MOSSES. 



Bryopis pllmosa,* Lam. 



Pcrlups the most beautiful of our green Algx is 

 the one here rumcd. 'ITic artist gives, in Pblc I., 

 an admirable representation of a ty-pical plant col- 

 lected by my frienti Mr. A. R. Young, at Hell Gate, 

 N. Y. The i>iciurc will give you a belter idea of 

 this interesting plant than any description in mere 

 words. But it had belter be laid. that it com- 

 monly grows in tufts, a considerable nnmlxrr of 

 fronds from the same point, from ♦w- i^ .„x inches 

 high. 'ITie leading fibmcnl is U^^v all around, or 

 sometimes on two opi*osite sides only, with long 

 widely spreadmg branches, which are shorter toward 

 the top of the plant These, in llieir upper half, 

 are clothed with long or, short, fUaight, bran so 



placed as to give the plant a decidedly plumose or 

 feathery appearance. It grows ujwn th^ 

 parasitical upon other Algx in shaded tide ix>. 

 along our rocky shores. Mr. Collins informs me 

 tlial it may be found upon the muddy bottoms of 

 Mysuc River, "where the tide ebbs and flows twice 

 in tvkxnty-four hours." I found some very beautiful 

 specimens of it growing in a clear pool beside over- 

 hanging rocks, on Ram IsUnd, off the Marblchcad
