Books on the flora of southern Brazil’s Araucaria forests?

Hello,

I’m looking for the best books you can recommend me on the flora of southern Brazil’s Araucaria forests. The book would have content regarding all flora found in its ecosystems, including a comprehensive listing and description of tree species.

Strong preference for lots of color photographs (only illustrations doesn’t do much for me). Book can get very technical, I prefer to stay away from books targeted to the “lay reader”, want to stay away from anything too “dumbed down”, no offense to anyone.

Can be decades old, out of print, etc., as long as I can find it secondhand online. Can be in Portuguese or English, I don’t have a preference. I can read both languages.

I prefer a book that is comprehensive, complete, detailed, rather than condensed and shortened.

Thank you!
