=Distribution.=--New York to Nebraska, south to Florida and west to
Texas. In Indiana it is known to the author from Sullivan, Greene and
Clark Counties and southwestward. It has been reported from Jefferson
County by Barnes which is no doubt correct. Doubtful records are those
by Brown for Fountain County, Miami County by Gorby, and Phinney's
report for the area of Delaware, Jay, Randolph and Wayne Counties. It
has been reported for the vicinity of Chicago by Higley and Raddin. It
may be local on sterile, sandy ridges of the northern part of the State,
but very local if it does occur. It is generally found in very poor soil
on the crest of ridges associated with black and post oak. However, it
has been found in Greene, Sullivan and Knox counties on sand ridges and
at the base of sand ridges associated with black and post oak. The
species has a very limited mass distribution and is only occasionally
found and in colonies of a few trees each.
=Remarks.=--Trees too small and scarce to be of any economic importance.
