Location is the Botanical Garden of Rio de Janeiro, it was not labelled!
The very thick central leaf nerve made me think of Philodendron crassinervium, the flower not though, I hadn't noticed it at the time as I could not approach close to the plants, everywhere there are guards whisteling you back when you get off the main paths to see or to photograph more details of a plant!
The thing is that the general leaf shape looks bigger, much broader and on top wavy edged what i haven't seen in the wild species..
