Description: This is one of the commonest pondweeds, rather robust, with the leaf bases perfoliate (wrapped around the stem). All the leaves are under water; there are no floating leaves as in some other common Potamogeton species. It is common in lakes, ditches and slow rivers and streams, and is tolerant of quite a wide range of nutrient status.

All names: Potamogeton perfoliatus L.
