The taxonomy presented here follows that of Garrett E. Crow and C. Barre Hellquist. 2000. Aquatic and Wetland Plants of Northeastern North America: a revised and enlarged edition of Norman C. Fassett's A Manual of Aquatic Plants.University of Wisconsin Press.

RED indicates genus contains INVASIVE SPECIES but not all species may be invasive.
The camera icon indicates those pages with photographs

Not all families or genera are included here. The included families/genera represent those I have typically seen over the years while conducting aquatic plant surveys on lakes and ponds in NY and NH, those that contain invasive species of concern, or those that contain exciting rarely seen species. I will be adding photographs as time and resources allow. Enjoy!

While every attempt has been made to correctly identify each specimen to species, misidentification may have occurred in some instances. Please let me know if you disagree with an identification shown here.
