fide J. G. Agardh, Epicrisis Floridearum, 1876, p. 700) ; 

 San Francisco! (G. W. Lichtenthaler); Lime Point, San 

 Francisco Bay! (C. P. Nott) ; Duxbury Reef ! (W. A. 

 Setchell); Fort Ross! (C. P. Nott). 



By way of summarizing some of the features mentioned 

 in the foregoing account, the following table, showing the 

 distribution of species within Californian limits, is incorpo- 

 rated. It will be seen that ten species occur on the coast. 

 These have now been reported from twenty-eight localities, 

 ranging from San Diego northward to Puget Sound, Wash- 

 ington, and points on Vancouver Island, B. C, embracing 

 twenty degrees of latitude and fourteen hundred miles of 

 coast line. It may be pointed out that there is here a 

 coastal distribution equal to that of the Atlantic shores of 

 Europe and the Mediterranean together. 



In the light of the evidence collected from a wide range 

 of material in field and herbarium, the ten species recog- 

 nized may be considered valid until more extended com- 

 parison with European specimens proves their identity with 

 previously described species.
