Looks like an orchid of some sort.

I agree with eloise. By the way have you seen any brazilian grape trees around there? Thanks Marcie

some species of a Catasetum orchid

Catasetum. Catasetum is a very interesting genus in that it has either male or female flowers. Only the male flowers vary. The female flowers (these are female) are almost identical even though there are many different species, so a more accurate ID is impossible.
