Three Segmented Walnut
Name: Gilbert M.
I have an English walnut with a 3 segment shell rather
than 2 halves. It seems like a real oddity, similar to a 4 leaf clover.
Do you have an opinion as to how unusual this might be? I have not found
any references about such an odd nut.
English walnuts (Juglans regia) are "non-splitting", with one embryo inside the nut.
The segments might be considered "artificial" or it is possible for physiological variation.
The following might be helpful.
