Bathroom decor ideas (rainforest look)?

I would really like to do my bathroom in a rainforest kind of theme. Not like a corny childrens rainforest look or things with monkeys and stuff. I would like it to look cly but earthy and clean. I'm really fond of dark greens, browns, oranges, tan and red. Also I can't paint my bathroom because I live in an apartment. Right now I have a really nice orchid that looks rainforesty and some other stuff but it doesn't feel very complete. I would like to do more. Any sugesstions?
