Hi Andre - to help me please send an image of the growth habit (i.e show whether its a tree or a shrub) - as it stands your image could be S. microphylla or S. molloyi or even (possibly) a hybrid involving one of the Chilean species. For Sophora if you want good identifications from images you need to show growth habit, foliage, and if you can flowers, and describe the hair distribution and morphology on the leaflets.
Ciao Peter
