The walnut family can always be separated from the 
hickory family by the fact that the pith in the former 
is split into thin brown plates while the pith of the 
hickories is solid. By cutting across a twig the family 
ean be determined, while the bark or leaves will separate 
the walnut from the butternut. There are two other 
walnuts in the United States one being found in 
Colorado and New Mexico, the other in the California 
coast region.
