highly developed. Our species shows the character of both 

 genera at once, if indeed it is not an intermediate form. 



To propose a new generic position for such a plant as this, 

 which stands between two genera so closely allied as Turbinaria 

 and Sargasswn would be unacceptible. I provisionally mention 

 the problematic species under Turbinaria, expecting that a closer 

 study of the phylogeny of the two genera will probably settle 

 the legitimacy or illegitimacy of assigning it as I have done.
