lanceolate, entire ; nerve reaching more than halfway ; spo- 

 rangium oblong, curved, cernuous ; lid conical. — Hook. 1$ 

 Wils. t. xxiv.; Eng. Bot. t. 2060. ; (Plate 6, fig. 3.) 



On the banks of ponds, or on stones occasionally flooded ; 

 sometimes more strictly aquatic. Common. Bearing fruit 

 in summer. 



Monoicous ; forming loose, soft, green or yellowish tufts. 

 Stem creeping, flaccid, irregularly divided, rarely subpinnate ; 

 branches procumbent or suberect; leaves generally complanate, 

 crowded or distant, rarely subsecund, ovato-lanceolate, acute, 

 entire, slightly decurrent at the base; nerve reaching beyond 

 the middle ; cells narrow ; fruitstalk even, about an inch high ; 

 sporangium oblong, subcylindrical, curved; lid conical, acute. 



Extremely variable, resembling sometimes H. fluitans and 

 other aquatic species; Moug. & Nest. n. 1134 (at least in my 

 copy) is some short-fruited rough-stalked Moss, with ovate, 

 serrated leaves, and apparently H. rutabulum. When growing 

 in the water, it assumes sometimes the habit of Fontinalis. 

 Moug. & Nest. n. 1034 is apparently a state of H. aduncum.
