| Facultative submerged aquatics | Ceratopteris thalichtroides
Marsilea crenata Microsrium brassii Microsorium pteropus |
| Obligate free-loating aquatics | Azolla pinnata
Salvinia molesta |
| Facultative free floating aquatics | Ceratopteris thalichtroides |
| Nearly always emergent aquatics | Acrostichum aureum
Acrostichum speciosum Marsilea crenata Ceratopteris thalichtroides |
| Facultative emergent aquatics | Ampelopteris prolifera
Cyclosorus interruptus Stenochlaena milnei Stenochlaena palustris Thelypteris confluens |
| Often swamp or lake margin plants | Acrostichum aureum

| Obligate rheophytes | Equisetum debile
Microsorium brassii Microsorium pteropus |
| Facultative rheophytes | Stenochlaena palustris |
| Mangrove swamps | Acrostichum aureum
Acrostichum speciosum |
The following species, arranged alphabetically, are rheophytes, some obligate (indicated with "*", some facultative. Most are immersed for only short periods and are not considered as truly aquatic in this treatment:
Note: In spite of its name, Rheopteris is neither aquatic nor rheophytic. It is in fact an epiphyte, originally collected and described from material washed down a stream. It is an interesting if problematic genus and has been variusly plced in a range of families from Vittariacee to Adiantaceae; it does not sit comfortably in any of them.
