- Field Notes
- The Pondweed is not a marine plant despite its species name, but it is rather a fresh water plant that tolerates salt water.
The plant usually self pollinates but it can be pollinated by pollen that floats on the water after been released by the flower.
The fruits of the Pondweed are dispersed by fish and water fowl that feed on them but the plant can also sprout from its rhizomes and form colonies.
