Martin I was thinking along that same line leaf shape is similar along with fruit. My family is from Sicily and I was there two times when i was 12 &14. I would take my cousins motorcycle and ride up MT Etna. We even spent two nights up at the crater. Middle of summer but it is cold up there you would find little opening to sleep by where the heat would come from, and you would have to hold your breath during the sulfer releases. The town was Linguaglossa .
Any way I was also comparing to Negronne. Are the leaf shapes similar in these two?
