Ecology of Planted Aquarium
Ecyclopedia of Aquarium Plants
You already have the only two books that I've picked up so far, so I can't tell you anything that you don't already know. I've got:
- Ecology of Planted Aquarium
- Ecyclopedia of Aquarium Plants
I think that the Encyclopedia of Aquarium Plants has some of the info that you are looking for, but it appears that you are looking for more details than what is contained in there.
I'm watching this thread, to see if anyone else offers any useful ideas.....
