96-10a – There once was a spontaneous native Bur Oak (Quercus macrocarpa) on the grounds of Camp Lincoln that produced very long acorns. We have informally called it “Long Nut”, and this tree is one of two seedlings from it planted at Oak Ridge that were grown from those acorns in the 1990s. Bur oaks are very hardy here in Illinois and tolerant of many soil and weather extremes, and as can be seen by the unique shape of the parent tree’s acorns, they are quite variable from one end of the range to the other in a gradually changing geographic-linked morphology called clinal variation.
