Glossary of botanical terms commonly used in range research

This glossary has been collated at the request of field officers of the Forest Service primarily for use in connection with the important western floras and other botanical publications which contain no glossaries. The text as originally prepared included only morphological and taxonomic terms but has been enlarged somewhat to include some of the more common terms used in plant ecology, physiology, and other phases of botany, as well as a few of the more common abbreviations and symbols used in the botanical sciences.
