growing in the latter habitat. Along the humus 

 shores the mid beach area is largely tenanted by 

 a Carcx-Conianim society, which lakeward passes 

 into the Hi ppiiris-Eqiiisctum front strand com- 

 plex already spoken of The characteristic 

 plants of the society are various species of 

 Car ex such as: 



Carex howellii Carex sitchcnsis 

 Carcx exsiccata Elcocharis palustris 



In some places occur scattered examples of 

 Veronica sciitellata. Comarum paliistre is found 

 in considerable quantities among the sedges 

 throughout, but reaches apparently its fullest 

 development well toward the back. 



Upon the sandy beaches and stream deltas 

 of the mid beach region is established a some- 

 what complex herbaceous society of mostly per- 

 ennial types. The composition varies but the 

 most characteristic plants are: 

 Agrosfis attenuata Lycopus communis 

 Agrostis exarata Bromus vulgaris 

 Elymiis ciliatus Oenanthe sarmentosa 



Carex decidua Galium tri fid urn pacificum 



This group does not exhibit signs of stability.
