feet long, and in the spread of the lobes two-thirds 

 as broad. The frond has usually a central body 

 with forked, tongue-like, marginal branches, an inch 

 wide and six or eight inches long. The lobes are 

 often crowded so as to overlap each other. No 

 veins are visible. Fruit dots are scattered over the 

 surface of the frond. The substance is rather firm, 

 but thin, and does not very well adhere to paper, 

 except in the younger portions. The color is dull 

 purplish-red, more rosy in the newer parts." 



I have seen only small specimens of this noble 

 plant. Dr. Anderson reports it quite common at 

 Santa Cruz, and when he also reports, that three 

 other of the largest species of this splendid genus 

 are among the commonest plants in those waters, I 

 cannot help wishing that that El Dorado of the Al- 

 gologist were not so far away. He says all the 

 species of Nitophyllum grow between tides, on rocks, 

 and on the roots and stems of Laminaria, of course 

 in tide pools, all the year round. No doubt they 

 grow in deep water there also, as they do, according 

 to Dr. Dimmick, at Santa Barbara.
