Hi everyone, I found both of these plants about 6 weeks ago and still can't ID them. Anyone, help? Thanks, Jimjim

jimjim,
Your first plant looks like a Potamogeton, maybe P. pectinatus. Or I could be way off. The second plant looks very scape-able. Both plants look very nice!

First one might be a potamogeton or Zosterella dubia. Do the leaves have a noticable center vein? It has flowers on it? It is very important to photograph the flowers close up in order to ID it.

ID these plants

I guess I was asleep at the wheel not recognising the Sago pondweed (P. pectinatus). The other one tho threw me completly, thanks tsunami. Thanks all for the help, Jimjim

P. pectinatus is P. diversifolius

The first plant I had at the begining of this thread has surprised me with the changing of their leaves. In medium light they stay like the picture shows, in high light they turn into small spadelike shapes. I've got to buy some batteries for my camera but will post pics tommorrow. It leads me to think the Sago pondweed is really Potamogeton diversifolius especially since they look very alike until they change leaves...Jimjim

The first plant looks to me like Zannichellia palustris, Horned pondweed. I once got this plant out of Lake Mendota in Madison, Wisconsin, but I never tried it in a planted aquarium to see how suitable a community plant it would be. Unlike Potamogeton, it has underwater fertilization.
