Water Plants
The land plants, from mosses to flowering plants, all share an aquatic ancestor that left the water to conquer new territory. Today's aquatic plants all had terrestrial ancestors that changed their minds: they left the land and re-adapted to life in the water.
Among the land plants, 103 families and 440 genera include aquatic species (Cook 1999). Only about 2% of angiosperm species are aquatic, but across the angiosperms, aquatic lifestyles are estimated to have evolved at least 200 times (Cook 1999). Add in some aquatic ferns and lycophytes, and the aquatic tracheophytes are a fascinatingly diverse group.

Thanks for making this project! I've already have found it incredibly useful. Some missing taxa that should be added (found using search filter ¬_in_project=water-plants):
-- Posidoniaceae (sole genus being Posidonia)
-- Juncaginaceae (arrowgrasses)
-- Sparganium
-- Several Oenantheae genera -- incl. Oenanthe, Sium, Helosciadium
-- Many Cyperoideae are still missing -- incl. Bolboschoenus, Actinoscirpus
-- Aquatic Mosses (currently none in the project) - probably an external resource out there with a species list, but includes Fontinalis, Fissidens fontanus, etc.
I'd be happy to help make the project more complete if that's a goal of such. Would you prefer missing taxa be commented here, or would it be preferable to make me an admin of the project so I could directly add them?
Adding on to above:
-- Rhizophora (mangroves)
-- Several Ludwigia, incl. Ludwigia sedoides, Ludwigia helminthorrhiza, Ludwigia adscendens
-- Batrachium (Water-Crowfoots)
-- Ranunculus flabellaris, Ranunculus trichophyllus, other aquatic Ranunculus
-- Thalia
Adding some of these now...
OK-- Posidoniaceae, Juncaginaceae, Sparganium are in
Oenanthe, Sium, Helosciadium: I have individual species of these in, but based on my aquatic plant reference, was under the impression that not every member of these genera counted as truly aquatic, though most do like wet habitats.
Sedges are a work in progress -- the nomenclature is a nightmare.
Mosses (non-vascular) and mangroves (woody) don't currently fit the scope of this project.
All of the other taxa you listed are now in.
Thanks for making this project better!
