In contrast to Potamogeton the structure of the Aponogetonaceae 
and Juncaginaceae is much more typically monocotyledonous. This 
is proved by the course of the bundles, which have been carefully 
followed and compared in all of the species under investigation, by 
the greater frequency of amphivasal bundles, etc. Indeed, the author 
is inclined to hold that the relationships of these families are with 
the Alismaceae rather than the Potamogetonaceae.
