Hab. Margins of swamps and wet springy places, on the 

 ground and decayed logs : very common and variable. 



H. orthocladon, H. conlextum, H. tenax, H. inordinatum, and 

 H. variuni, attributed to this country only, are (together with a 

 few other supposed species, including H. radicale, found both 

 here and in Europe) so variable in their characters, and pass so 

 gradually into each other, that it appears to be quite impracti- 

 cable to define their specific limits, or to separate them from 

 large forms of H. serpens, to which they have been referred by 

 Miiller and others.
