No, it wasn't just the wrong picture. The latin name for amazon "compacta" sword is Echindorus bleheri "compacta." I can't find "echino xingu" on any other site than the aquadise one. I still think the grass like plant looks more like vallisneria, since it looks straighter than sagittaria. Sag seems to bend over more than val.ACK! it is....I guess it was just a wrong picture, and the grassy one does look like sagittaria....
and yep cryptcorne balansae is right....

Something interesting is how similar these two plants look.
