Being that Adam is not checking the forum, it would be difficult to ID this jaboticaba, but I will post it anyway... there are a lot of forum members that grow jaboticabas and there are some "maniacs" and jaboticabaholics here so I have some hope...
The leaves remember me the red jaboticaba (myrciaria aureana x myrciaria cauliflora), but this is not possible as the source is from Misiones and almost nobody grows red jaboticaba here at Argentina. So I am thinking it could be myrciaria cauliflora or something similar... but I am not good identifying plants.
