Some plant identification

Went to the petstore and saw some more Acorus, that's defniitely what it was.

http://www.lusteraquatic.com/aquarium/spathiphyllum.html - Looks almost exactly like what I have. Oh well, I have bad luck with them.. no big deal, it's gone now.

picked up a true Amazon Sword.. huge plant, already flowering (and running flowers across my water surface), I think it might do alright.

Also picked up a poor looking ornamental sword and ... mondo grass (which isn't an aquatic plant apparently? I got screwed again? I need to stop buying plants on impulse, ugh).. I had some grass-like plant similer to the JungleVal I have that took over this aquarium when I was using sand. It created a nice bed and the fish loved it.. I'm trying to find something that will do that in this tank and look nice. I'm about ready to get rid of the Jungle Val, it's growing nicely but I have to trim it all the time to keep this stupid hair algae off of it. It's looking pretty poor since I treated it with excel (was told it might happen)

I've never had much luck with Java Moss creating a cover on substrate, it ends up being a lot of work getting it tied down. Is this Riccia I've been reading about any good? Can't find any locally but maybe I can find some cheap Riccia on the internet. I did see some at walmart in a pot once.. it would be nice if I could simply drop the pot in my tank and let it spread over the substrate.
