(2454.) P. Scouleri, Hook., Fl. II., 171. 



Abundant on steep rocks below half tide, from the lighthouse, near 

 Victoria, around the coast to Esquimault Harbor ; very common in the 

 same situations on all the islands in the outer part of Barclay Sound, 

 on the west coast of Vancouver Island. (Macoun.) ' 



Although much like Z. marina in general appearance, its place of growth 

 differs so materially that the two species need never be confounded, as 

 this always grows on steep rocks or on boulders, while the other 

 delights in pools with a bottom of shell mud. Pine fruiting specimens 

 were obtained in July and August, 1887. It is very likely quite com- 

 mon on the Pacific coast, but usually confounded with Z. marina.
