204 SEA MOSSES. 



In color, it is very dark red when fresh, and 

 quite black when dry. It is a perennial, and so may 

 be looked for at all seasons. It grows in deep 

 water. I have taken it at Marblehead and Newport. 

 Mr. Collins reports it in various places about Massa- 

 chusetts Bay, in the summer and fall, in tide pools. 

 Mrs. Davis gets it at Annisquam in a mill pond. 

 Mrs. Bray finds it washed ashore at Coffin's Beach, 

 Gloucester. AU report it common. Miss Booth finds 

 it scarce at Orient. It does not adhere to paper, 

 and is far from being, to the generality, an inter- 

 esting plant.

Nemalion multifidum, Ag.

 the sea bottom, which are uncovered at low tide. 

 It much affects the smooth, rounded surface of the 

 hard, granitic, sea-worn boulders, which lie low down, 

 between tides, all along our New England coast. 

 Where nothing else seems able to make a foot-hold, 



* Nemalion = Crop of strings.
