I have liesitated to add the I^orth and South American species 

 of IL/j7^oj>hiIa to the syuonjmj adduced for this species. AVheii 

 I examined the American species of this gouus in the Iloolvcriaa 

 Herbarium, which contains Nees von Esenbeck's autlientic spe- 

 cimens, I failed to detect any of the specific differences detailed 

 by that author in the ' Prodromus.' The slight distinction that 

 existed among the various specimens seemed to me to be no 

 greater than ought to be found iu a very common species of 

 aquatic weed extending over many degrees of latitude. I am 

 convinced of the correctness of referring all !N"ees von E^^cnbeck's 

 so-called Asiatic species of ILjgrophila to one widely-diffused 

 plant. I have seen examples of nearly all his so-called Asiatic 

 species growing within a few yards of eacli other in ditches by 

 roadsides both in Ben<^al and Java, the differences between each 

 specimen being evidently caused by that in the amount of mois- 

 ture to which each was exposed.
