Atlantic Bhores of Britain. On muddy Bea-shoree 

 high-water mark; at the estuaries of rivers; in salt-water 

 ditches and marshes, adhering to the roots of flowering- 

 plants; said also to grow on submarine rocks. Annual? 

 Summer. 

 A curious plant, interesting because it occurs in situa- 

 tions more nearly bordering on fresh water than are 

 pied by any other individual of the RhodoTTielacecB, a tribe 

 of Algae peculiarly impatient of fresh water, and which 

 generally grow at a considerable depth ; interesting, 

 because it forms a connecting link between several genera. 

 Some doubt hangs over the capsular fruit of this s] 

 which has only been observed by Both, if his vagn 

 Bcription can be considered conclusive; nor are the si 

 dia of frequent occurrence.
