 Myriophyllum ambiguum var. limosum Nuttall, Gen. II. 212. 1818. 



Ponds of the Pine Barrens, Middle and Coast districts, fre- 

 quent. 



Most of the records of Myriophyllum heterophyllum and 

 verticillatum for our region appear to belong here. The species 

 presents a great diversity of form, small plants creeping in 

 mud are form hiiinile, those entirely submerged in deep water 

 are capillacea, 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."
