I found this picture............this is about 40km from my house................
I live in São Paulo City...........Brazil..............and this picture is from the Atlantic Forest....................called Serra do Mar...............
I don´t know the species..............but I made some search and I found that they may be Feral species..........but unidentified species..........
I´m not personally convinced that this is a Feral species................
Along the stream one can see that there are more Bananas at the Forest Borders..........
