I think I see some sort of crypt hiding near the right end of the
driftwood. I'm guessing that the stuff on the left, as well as the stuff in the front/center is some sort of sword, though I don't know what.
The tall, frilly stuff might be watersprite (I've never owned it, though, so I'm not positive on that, either)
There's some broad-leafed stuff that looks kind of like spades (as in the card suit) that I think is anubias. If it is, it doesn't like being buried. It likes to be anchored to a piece of wood or rock (can't tell if it's rooted or resting on the wood)
