Identify water plant please
Please help me identify this freshwater aquatic plant. I am trying to
get a picture but so far not available. The plant floats with stem segments about 2" (50 mm) long, the top of the leaves are above the surface and they are dense on the stem with very short stalks so only the leaves are visible from above. The underside of the segments have a mat of dark greenish roots hanging down about 1/2" (12mm) to 1" (25mm). The leaves are oval, a uniform bright green about 1/2" (12mm) long and 2/3rds of that wide. The leaves occur mainly in pairs on the stem, each leaf has a crease down the centre in line with where it is attached to the stem so that the top is slightly concave. The upper surface is covered with short hair-like protruberances and sheds water. The leaves feel soft and fleshy to the touch. David |

Salvinia, perhaps?

Thanks Yes, that's it. Declared noxious here as it is so invasive - so much for that idea. David I have the stuff here in CT it came by way of a pet store with tropical fish. It is an EXTREMELY fast grower and spreader. I would be wary of it south of Philadelphia. In one summer a fistfull of the stuff covered the surface of an unused swimming pool about 4-6" deep. For me it works as a biofilter as I harvest it from my aquariums and use it as mulch thus removing excess nutrients. Again you don't want this plant anywhere it's warm. |
