Plant ID's Please!

"Anacharis" is a name which should be dropped. It's used of a number of plants in the genera Hydrilla, Elodea, Egeria and Lagarosiphon. It was dropped as a scientific name over 50 years ago.
 
I have to say this Hydrilla isn't as nice as the "anacharis" I've seen around and was hoping I was getting... Its pretty messy and drops roots from pretty high up the stem. They do grow fast though and seem to be doing fine in my tank. I guess I'll just have to trim it into the way I like...
