Newt posted links to Farkleberry which is similar looking, however,
there are pretty significant differences in leaf shape, bark, and
flower /bloom configuration. We have numerous large Farkleberry trees
on the property. To illustrate the difference, I have photographed
these side by side the mystery tree at the following link. The password
is "tree". Thanks for your interest.
