Importance of the Bud Buds are the location of NEW STEMS,FRUITS, and LEAVES. The bud is an undeveloped shoot andnormally occurs in the axil of a leafor at the tip of the stem.

In the process of identifying trees, thereis a logical sequence to identify the treeof interest The “tool” that is used is adichotom ous key A dichotomous key is a tool that allows the user todetermine the identity of items in the natural world,such as trees, wildflowers, mammals, reptiles,rocks, and fish. Keys consist of a series of choices that lead theuser to the correct name of a given item. "Dichotomous" means "divided into two parts".2/1/2019Identifying Kentucky’s24Treeswww.ukforestry.org
