PREFACE

The native trees of West Virginia number about 125, of which 101 are described and illustrated in this publication. The omissions are principally species of unimportant willows and hawthorns which can be identified only by specialists. Some of the more common introduced trees are mentioned in the family descriptions on pages 13 to 27, and a few are illustrated in groups after the descriptions of native species. It has been the object to simplify everything in this publication as much as possible. The meaning of unfamiliar words in the keys and descriptions can be learned by consulting the glossary beginning on page 237.

The keys are based principally on characters of leaf and fruit since these are usually available for study during several months in the summer and fall. The text, however, contains brief descriptions of the flowers which often denote most surely the natural relationship of species.

Scientific names and the order of arrangement are essentially those of the seventh edition of Gray’s New Manual of Botany.

The drawings were made by the writer from specimens collected during the past few years.

This bulletin has been prepared mainly for those who desire to become more familiar with our native and introduced trees, but who do not have access to the larger publications on the subject. It will serve also as a basis for future forestry studies in the State. Popular interest in forestry, which is sadly lacking in West Virginia at this time, will be stimulated by a more general and more intimate acquaintance with the different kinds of trees. It is hoped that this bulletin will help to create the needed interest. If difficulty is found in determining the name of any tree, specimens mailed to the West Virginia Agricultural Experiment Station, Morgantown, West Virginia, will be named, if possible, without charge.
