 Quillwort should be placed in a good light. It is eaten by some snails 

 and fishes. Not easily obtained. 



FONTINALIS 



Known as Willowmoss, these plants are found attached to stones or 

 other substantial objects. They are of a pleasing dark-green color and 

 have the advantage of doing well in a subdued light, although a moderate 

 amount of direct sun does them no harm. 



Fontinalis antipyretica grows in long-branching form, with leaves 

 closely adhering to the stem. It occurs in cold-water streams. Very 

 plentiful in some localities, but not freely distributed.
