Flowering in Echinodorus is extremely variable. Some like emersed
conditions, while others flower only in a submersed state. Daylength is
also supposed to be a factor in flower induction. Since there wasn't any
other interest on this subject, I'll email you the specifics for the E.
species I have info on.
