Hi Myriam,
Tricky! It reminded me of a Cashew tree, so I looked in family Anacardiaceae on Flora Brasil. I looked at each genus, one I found came close but the species was different. Campnosperma brevipetiolata.. .

Listed is Campnosperma gummifera for which I can't find a photo, but it has other names..

The Flora do Brasil site is working now..

By searching Drepanospermum gummiferum I found a drawing of the leaves of Campnosperma gummifera..
