LYCOPODIACE^E. 



Lyc op odium selago L. Cascade and Olympic Mountains. This

 Occident ale by the editor in the January Bulletin. This grows 

 in dense coniferous woods about the base of Mt. Tacoma. It 

 is possible that it may be made a distinct species when better 

 understood. It seems to be quite abundant in a limited area.

 near Tacoma, though not seen by the writer elsewhere. Alluvial 

 meadows. 



Lycopodium annotinum L. Not very abundant. Foothills of 

 Mt. Tacoma ; also reported from the southern part of the State. 



Lycopodium clavatum L. Common club moss. Common in 

 the dense forest between the Cascade Mountains and Plight
