The West Indian Salicornia formation closely corresponds with 

 the Salicornia formation of the Danish shores, and the West Indian 

 species and Salicornia herhacea L. are also nearly related, after

 As already said it greatly resembles Salicornia herhacea L., but is 

 somewhat more slender and has almost evenly thick, cylindric 

 branches (fig. 17). The branches are sometimes erect (c. ^2 meter
