coast ; but more common south of Cape Cod. It is 

 common in southern California. It is but half the 

 thickness of the other, and is not nearly so stiff and 

 rigid, and grows not solitary, but in tufts, from three 

 to twelve inches long. The filaments are considerably 

 constricted at the joints. The articulations are about 

 as broad as long. The color is yellow green, fading 

 in the herbarium, and turning darker. Young plants 

 are straight, but the old ones are often bent. It does 

 not readily adhere to paper. 



Ch^tormorpha Olneyi, Harv. 



Filaments in tufts, about the size of the last, as thick 

 as a brisde, straight or bent, or much contorted ; pale 

 green ; articulations once and a half times longer than 

 broad. It is of a much softer substance than the last, 

 though it feels harsh when dried on paper, to which it 

 adheres firmly. I found it beyond the first beach at 

 Newport, Aug. 7, imich contorted, like C. Picquotiana. 

 It was named for Mr. S. T. Olney, of Providence. 



Ch.^tormorpha Picquotiana, Mont. 



Filaments loosely bundled together in masses; grass 



green ; rigid, glossy, twelve inches long or more, twice 



as thick as bristles, variously curved and twisted ; 



articulations tliree to five times as long as broad
