linearis?), Viola lanceolata, Juncus scirpoides, Osmunda regalis 
(O. spectabilis), and Aspidium Thelypteris (Dryopteris Thelypieris). 
In the Hudsonia complex, as previously noted, are many small 
swamps. The segregation of species in these swamps is most 
singular. Neighboring hollows may have almost totally different 
associations. One may be carpeted with cranberries, while in
