This variety appears to be the result of a natural Chinese-Japanese
cross. The original tree was grown by H. F. Stoke, Roanoke, Va., whose
attention was attracted to it because of its habit of maturing early. He
reports that in southwestern Virginia, burs often begin opening during
the third week of August. In appearance, the nuts greatly resemble pure
Japanese. The parent tree bears well but the nuts are lacking in good
quality. Insofar as known propagation has been discontinued.
