I've harvested several of those, and the property owner told me they were Persimmon. What he did, is had me cull out some of the male trees to make room for fruit bearing females. The bark and the leaves are distinct. Makes good bows Mark, but I learned the hard way not to force the drying. Reduced the very first split to get rid of mass, and it checked so badly that daylight could be seen through the checks. It is a hard dense wood that was once used in golf club heads.
