PLANTS OF NORTH ELBA I 53 



Lycopodium annotinum L. 



Stiff club moss 



Hidden swamp, Indian pass and side of Mt Mclntyre near the open 



summit. 



L. annotinum pungens Spring 



Open summit of Mt Mclntyre. This variety differs from the type in 

 its shorter, more sharply pointed and usually more erect leaves. 



Lycopodium obscurum Z. 



L. obsairum var. dendroideum D. C. Eaton 

 Ground pine. Tree club moss 

 Woods and open places. Common. August. This ascends to the 

 top of Mt Mclntyre, but I have seen no fertile specimens there. This 

 club moss is easily known by its tree-like form. The L. obscurum of the 

 Manual is a form having the upper row of leaves smaller than the 

 others and appressed to the branches. It is more rare than the other 

 form and not recognized as a distinct variety in Illustrated flora. I 

 have not seen it in North Elba. 



Lycopodium clavatum L. 



Running pine. Club moss 



Thin woods, old clearings and groves of young coniferous trees. Com- 

 mon. August. A beautiful species. 



Lycopodium complanatum L. 



Trailing Christmas green. Festoon ground pine 



Habitat as in the last. Both are used in decorative work in the 

 holiday season and are excellent for wreaths and festoons. 



L. complanatum Chamaecyparissus D. C. Eaton 

 Abundant on dry hillocks south of the railroad near Raybrook. 



FILICES 

 Polypodium vulgare L. 



Common polypody 

 Woods and shaded places, often on rocks or large boulders. Common. 



Adiantum pedatum L, 



Maidenhair 

 Damp places in woods. Near Wood's sap works.
