Affinities. These are not at all made out. Iii consequence of the 

 number of its cotyledons, Richard placed it near 'Conlferae, with which it 

 seems to have no kind of affinity. Decandolle urges its relation to Hippuris 

 and Myriophyllum, among Haloragese, from which it differs in its superior 

 ovarium ; and he inquires whether Naias, vVhich according to some is dico- 

 tyledonous, does not belong to the same order. Can this family have any 

 relation to Podostemese? Agardh places it among Fluviales.
