Could be Myrciaria glomerata... common name Red Cabeludinha
Wild, well yeah Adam is the source that brought them in years ago. Your friend must have needed to prune to cut big sticks off an extremely rare tree of that rareness. Best bet is to graft them on Myrciaria Glazioviana or maybe you can work some rooting magic.
