Abstract

The purpose of the following presentation is to call attention briefly to the value of the twig and bud characters used commonly in winter keys, as supplementary or secondary characters in the keys for the identification of trees in summer condition. For the past few years the writer has been studying the winter characters of our woody plants. Many of the characters that are used to distinguish between difficult genera or species in winter were found to be present the succeeding summer and became a definite help in identification.
