VASEY PONDWEED 

 (Potamogeton vaseyi) 



Minnesota to New Brunswick, Illinois and 

 Pennsylvania. 



Leaves are scattered and almost hairlike 

 and have long- tapered tips. Often there are 

 tiny, short-stalked winterbuds in the angles 

 between leaves and stem. Sometimes there are 

 floating leaves (see page 10). 



Resembles Snailseed Pondweed but all the 

 seed heads are long-stalked; the seeds have 

 convex sides; and the base of the underwater 

 leaves does not make a sheath around the stem. 



SNAILSEED PONDWEED 

 (Potamogeton diversif olius ; includes 

 bicupulatus, capillaceus and spirillus) 



Montana to Newfoundland, California, 

 Texas and Florida. 



Sometimes there are floating leaves 

 (see page 10). 



Resembles Vasey Pondweed but has short- 

 stalked or -stalkless, ball-like underwater 

 seed heads; seeds resembling flat snails; 

 and underwater leaves with a base that makes 

 a sheath around the stem.
