College should be consulted. No attempt will be made at 
elaborate synonymy; the names will as a rule follow Setchell & 
Gardner, 1903, and references will be made to that work, to 
Harvey's Nereis, Collins’ Green AIgse of North America, and 
to such monographs as may seem desirable. Reference will be 
given to the Phycotheca Boreali-Americana for all species there 
distributed, whether the material distributed came from 
Vancouver or some other region. The Geological Survey has 
a full set of the work. 
To Professor W. A. Setchell, of the University of California, 
the writer is indebted for valuable information as to type 
specimens in European herbaria; all references to such speci- 
mens in the following pages are from Dr. Setchell.

abundant it gives a greenish shade to the host, but otherwise 
is only to be detected by microscopic examination. Esquimalt,

and his plants may possibly be referred to one of the following
