■whom the genus was named, but the type locality (fide Dr. Eisen) is 

 Santa Catalina Island. Areschoug also reports it from Santa Cruz, 

 California, on the authority of Dr. C. L. Anderson, who has told us 

 that his plant was found floating. We have no knowledge which seems 

 to us to be authentic of its occurrence, growing in position, north of 

 Redondo, California. We have no data as to its southern limit of 

 distribution, but we presume that it extends to some distance south 

 along the coast of Lower California. 



tribe 3. EGREGIEAE setchell 



Members of the Alariaceae having irregular branching and out- 

 growth of sporophylls on both stipe and blade. 



Setchell, Kelps of the U. S. and Alaska, 1912a, p. 161. 



There is a single genus of this tribe, with two species, both con- 

 fined to the western coast of North America. 



58. Egregia Aresch. 



Holdfast a very densely compact mass of repeatedly branched hap- 

 teres; stipe irregularly branched near the base, terete below, each 

 branch soon becoming ligulate forming a rhachis and bearing out- 

 growths on each margin nearly throughout its length ; some outgrowths 

 metamorphosing into conspicuous stipitate bladders, some becoming 

 ligulate and sterile, and some remaining small and bearing sori of 

 zoosporangia on both surfaces. 



Areschoug, in Bot. Not., 1878, no. 3, p. 66, Observ. Phycol., part 5, 

 1884, p. 3. 



The genus Egregia was established by Areschoug (loc. cit.) to 

 receive the Fucus Menziesii of Turner. Menzies collected it at 

 "Nootka, Trinidad and Monterey." 



Key to the Species 



1. Sterile, lateral outgrowths linear spatulate 1. E. Menziesii (p. 647) 



1. Sterile, lateral outgrowths ligulate 2. E. laevigata (p. 648) 



Egregia Menziesii (Turn.) Aresch. 



Compact mass of hapteres arising close to the base of the stipe, 

 by repeated branching, often growing up around the base of the 

 stipe; stipe smooth, nearly terete at the base for 8-15 cm., branched 

 several times, soon becoming ligulate, forming a rhachis; rhachis
