 First proposed as a distinct species by Dillwyn, 

 draws attention to its peculiarly pale green col >ur and 

 bushy mode of growth. These characters, taken in 

 tiou to the robust thread-, spreading branches, and blunt 

 ramuli. may serve to distinguish it from our other n 

 kinds, bul it is more difficult to point out characte 

 which it may be known from a fresh-water sped 

 glomerata. Among such imperfect plants, however, 

 tat may. perhaps, be admitted as a character of no ordinary 

 importance, and if we allow it in the present case, there 

 can be no difficulty in the matter-, tor I
