I am actually have a fairly good handle on Milfoils in comparison to
Hornworts. Of course just decided to try and decyper the latter.
According to a source in Britain where the two larger species are also
native they go by the names Rigid Hornwort Ceratophyllum demersum &
Soft Hornwort Ceratophyllum submersum . Now to figure out which one is
the bigger, darker plant and which one is the smaller pale green one.
