I appreciate your request, but the context provided only shows "thumb|Walnuts" (which appears to be a wiki image caption), without any actual information about what walnuts are or why they matter. I cannot write an accurate overview based solely on this, as I would need to either use external knowledge (which you've asked me not to do) or have substantive context about walnuts provided. Could you share more detailed context about walnuts?

thumb|Walnuts
thumb|upright|Inside of a walnut in growth thumb|upright|Three-segment walnut right|thumb|Walnut shell inside its green husk thumb|right|Artistic depiction of two walnuts (Adriaen Coorte, 1702) A walnut is the edible seed of any tree of the genus Juglans (family Juglandaceae), particularly the Persian or English walnut, Juglans regia. They are accessory fruit because the outer covering of the fruit is technically an involucre and thus not morphologically part of the carpel; this means it cannot be a drupe but is instead a drupe-like nut.
