thefe capfules frequently occur on branches where no veficles are difcernible, and 

 the plant then confiderably refembles C. burfata of Muller, which my friend D. 

 Turner and myfelf found many years ago near Yarmouth, and which pofiibly 

 may not be a ditlin£t fpecies. 



C. feficata agrees fo nearly in the nature of the filament, in its ramifications ar.d 

 joints with C. amphibia in an old ftate, that I think it rather doubtful whether 

 future obfervations may not prove it to be only a variety of that plant. Its 

 brittlenefs, and rigidity, and under the microfcope its fingular veficles will, how- 

 ever, readily diftinguim it, and I have therefore thought it beft, and the moft 

 certain way of avoiding future confufion, to follow Muller, and publifh it as ,a 

 feparate fpecies. 



In drying it adheres very flightly to either glafs or paper.
