Scientific NamePotamogeton pusillus
Other Common Names:
Leaves are arranged alternately along the stem and are linear or ribbon-like in outline, approximately 1 to 2 inches long and only a few millimeters wide. A pair of glands occurs at the bases of the leaves, which are often difficult to see with the naked eye. The leaves also have stipules that are separate from the leaf bases and are approximately 1/3 to 2/3 inch long.
The alternately arranged narrow, ribbon-like leaves and stipules are both characteristics that help to distinguish this weed from other aquatic plants. Slender pondweed is often confused with southern naiad (Najas guadalupensis), however the leaves of this aquatic are arranged oppositely along the stem and have toothed margins unlike those of slender pondweed.
