Others have identified your plants, but neglected to mention that both Anubias
and Java Fern are able to grow attached to your dead tree instead of planted in
the gravel. Both could look really nice that way-the Anubias will extend it's
rhizome up the tree, sprouting leaves the whole way...

Do a google search on "planted driftwood" or "java fern diftwood", or look at
photos of the many planted tanks that do this.

Have fun and good luck!
