OR Are the leaves heart-shaped, is the fruit a small pod and are the spring blooms purple? If so, GO TO #40. Are the leaves oval shaped, are the flowers large and showy, and do the flowers grow at the branch tips? If so, GO TO #41.
You have a CHESTNUT. The American Chestnut was once widely planted, but American chestnuts have been damaged by blight. The Chinese chestnut is more blight resistant and more commonly found. (Your chestnut sample is just one example of a wide variety of trees that have simple, alternate, non-lobed leaves with toothed (jagged edge) margins. Some of these trees include holly, beech, certain oaks, aspen, linden, poplar, mulberry, hackberry, linden, alder, many elm species, birch, willow, many fruit trees, crabapple, hornbeam and hophornbeam...to name just a few.) Please take your tree sample to your teacher and he/she will let you know if you have correctly identified your mystery tree.
