Edible tree fruits, nuts, and leaves
The following trees have edible fruits but not all parts of the fruits may be edible and some people may experience idiosyncratic allergies or other bad reactions. Individual trees mentioned in Trees.stanford.edu may no longer be found at the designated locations either because they have died and been removed or have been removed for building renovation, relandscaping, or other causes. Trees.stanford.edu recommends that you do not eat any foraged plant material. Should you do so—just as in the case of fungi—be both positive of the identification of the plant and fully aware of the preparation requirements and potential dangers.Araucaria family
