ah right. I thought you were trying to ID a plant that looks like a bed, but do you just want to know different plants that can be attached to rocks/wood etc?
in that case, there's java fern, bolbitis heudelotii, loads of aquatic mosses, many anubias, fissidens ...., riccia fluitans, dwarf riccia, i think dwarf saggitaria can be as well.
i'm sure there are a few more.
