baceous species like Elymus ciliatus, Cardamine 
angulata, Viola glabella, and Washingtonia divar- 
icata. 
The remaining part of the backstrand ex- 
hibits general uniformity in its composition and

low predominate, Salix sitchensis and Sales 
lasiandra. The species of Carex observed in the 
mid strand societies force themselves 1n among 
the willows here and there but not im any con-
