Wildflowers: Identification of Leaf (Dry flower?)

Greetings to everyone, I am quite aware this is a long shot but I am very curious about it and thought it was worth a try. I recently found this leaf inside an old book, it came with a note saying it was found in the Colombian Amazon. I am curious as to which plant it can come from if someone has seen it before.

Thanks in advance and best regards!

 

Hard to tell. Could be Cleome gynandra
Or Passiflora
Or most probably something else.

 

With 130,000 species of wild plants Columbia of course is one of the most likely places in the world to find something not immediately recognizable.
