Stuckenia

Stuckenia is a genus of flowering aquatic plants. It contains approximately 30 species that grow in shallow water. Pondweed is a common name for plants in this genus.

Description
These herbs have rhizomes but not turions. Tubers can be absent or present. The main difference between Stuckenia and Potamogeton is that the stipule joins the leaf base. When it is pulled the sheath and stipule comes away, similar to a grass sheath and ligule.
