]\Iost of the records of Myriophyllum heterophyllum and 

 vcrticillatum for our region appear to belong here. The species 

 presents a great diversity of form, small plants creeping in 

 mud arc form Jniiiiilc,' those entirely submerged in deep water 

 are capillacca, and those with an emersed spike natans. 



Rafinesque proposed a new genus for the terrestrial form, 

 naming it in honor of Frederick Pursh, the first botanist to 

 publish his researches upon the New Jersey Pine Barrens. Un- 

 fortunately a typographical error in Rafinesque's paper makes 

 the genus "Burshia" in honor of "Mr. Bursh."
