The present species resembles very strongly L. ISinclairii 

 (Harvey) Farlow of the Central Californian coast in its hal)it 

 and in its possession of a creeping rhizome, hut diifers from it in 

 not having mncilage dncts in the stipe. 



Laminaria saccharina (L.) Lamom-onx. 



Forms of the trne L. sdcchdriiid are fairly abundant on the 

 coast from Puget Sound to the Alaskan Peninsula. It is not 

 known to enter the Bering Sea or to extend to the southward 

 of Cai)e Flactei-y in Washington, a distribution which is puzzling 

 from what we know of the species on th« coasts of Europe or 

 those of Eastern North America. The various older and modern 

 references are fairly readily placed under the forms described, 

 except the plants of Harvey (1862. ]>. 166) collected at 

 Esquimalt, B.C.
