Royal nut
During the Byzantine era, the walnut was also known by the name “royal nut”. An article on walnut tree cultivation in Spain is included in Ibn al-‘Awwam’s 12th-century Book on Agriculture. The walnut was originally known as the Welsh nut, i.e., it came through France and/or Italy to Germanic speakers (German Walnuss, Dutch okkernoot or walnoot, Danish valnød, Swedish valnöt). In Polish orzechy włoskie translates to “Italian nuts” (włoskie being the adjectival form of włochy (“Italy”)). (Wikipedia)
