out widely in lobes, like a hand with the fingers 

 extended, or remains entire, a foot long, rounded at 

 top, four or five inches wide, or displays one long, 

 tapering lobe and several smaller ones by the side 

 of it. It will thus be seen to be extremely variable 

 in form. But it has one mark which will infallibly 

 distinguish it, viz. : a network of branching, crossing 

 and interlacing veins, which covers over the entire 

 frond. The veins are very pronounced, and about 

 equally so throughout the frond. At least one other 

 species, of this genus, from these waters, has veins in 

 the frond, viz. : N. Ruprechteanum. But they 

 are mostly parallel, and rapidly fade out as they get 

 to the middle of the frond. Mrs. Bingham and Dr. 

 Dimmick find it not very common at Santa Barbara, 

 thrown up from deep water, in May and June. It 

 does not occur at San Diego. Dr. Anderson's report 

 of this and other Nitophylla, is given under the last 

 species, N. spectabile.

This plant was no doubt nam>ed for Mr. A. D.

 or a very common species. It attains a height of 

 five or six inches, and is spread to about the same
