land and the Provinces, as far as Halifax. Mrs. 

 Davis gets it on the beach at Gloucester, where it 

 is thrown up, from September to December. Prof. 

 Eaton found it at Eastport, Me. It may be ex- 

 pected at all intermediate points. 



It grows from a mass of short, creeping roots, 

 at first, a short, cylindrical stem, which gradually 

 expands into a flat, thickish, cartilaginous frond, 

 from one-half to one inch wide, and from two to 

 six inches high, tapers again at the top into a sim- 

 ple acute apex, or, forking, ends in two such apices. 

 Along the edges of this frond, at irregular intervals, 

 there come forth, at first, sharp, minute, spine-like 

 processes, usually curved. These at length grow 

 into miniature fronds of the same general form as 

 the parent frond. These again put out the spinous 

 cilia (" eyelashes," so called) which, in turn, be- 

 come still more minute fronds, of the original pat- 

 tern, having ciliated edges. Here, generally, the 

 ramification stops. The plant has a clear, strongly 

 marked red color, with a decided tendency to turn 

 darker in drying. It adheres well to paper.
