96-14 A oak hybrid, this tree is a vigorous F2 cross of bur oak (Quercus macrocarpa) with white oak (Q. alba) (= Quercus xbebbiana), and shows affinity toward the bur oak grandparent but retains the deeply dissected leaves of the parent, which was found in Washington Park in Springfield and has since been removed.

95-04 The native Bebb oak (Quercus ×bebbiana) is one of the most commonly seen hybrid white oaks in central Illinois. It often can be found where its parent species, white oak (Q. alba) and bur oak (Q. macrocarpa) grow together. This one is a seedling from the famous Taco Oak (Q. ×bebbiana ‘Taco’) found at the edge of a commercial parking lot on the west side of Springfield, thriving in a location with very poor growing conditions. The Taco oak now is being grown worldwide as a majestic, tough tree for difficult sites.

95-20a Bebb oak (Quercus ×bebbiana) is a relatively common oak hybrid on our area derived from bur oak and white oak (Quercus macrocarpa × Q. alba). It was grown from seed of the first State Tree from Morgan County that was planted on the northeast side of the Illinois Capitol, thought at the time to be a white oak. Later a true white oak was planted to the north across the entrance drive. Some of these F2 trees may revert back toward one parent or the other in various ways (acorns, leaf shape, fall color, bark, buds) and if you look closely at this and the two following trees you might see that happening here.
