FOREWORD

The purpose of the Northwest Common-Name CheckList of Plants is to help1. Improve communications about ecosystems between

scientists who are trained in scientific plant nomen-clature and the great preponderance of other scientistsand practitioners, such as range conservationists, for-esters, wildlife biologists, teachers, farmers, ranchers,youth groups and recreationists, who relate to plantsprimarily through the use of common names.

2. Provide a basis for uniformity in common plant namessuch as exists for birds and other animals in the North-west.

3. Perpetuate that unique historical feature of the old-time art of rangeland and forest management that isrepresented by the common names used by residentsand practitioners to identify plants locally and regionally.

Scientific Names

The scientific-name base for the Northwest Check Listis Northwest Plant Names and Symbols for EcosystemInventory and Analysis, 4th Edition. U.S.D.A. Forest ServiceGeneral Technical Report PNW-46. 1976.

All synonyms and, with a few exceptions, all subspecieslisted in PNW-46 are excluded from the Northwest CheckList. For practical reasons, common names have beenassigned to the plant-species level of taxonomy.

In addition to the species listed in PNW-46, a total of273 other species, which have been specifically identifiedin Oregon, are included in the Northwest Check List. Thesespecies were obtained by comparing PNW-46 with thefollowing reports:

Common Names

The Northwest Check List contains 4,120 commonnames representing 3,664 plant species (367 grasses; 196grass-like; 2,579 forbs; and 522 shrubs and trees). Somespecies are known by more than one common name andthese are cross-referenced in the Check List.

The primary authority for preferred common names isStandardized Plant Names, 2nd Edition, by Harlan P. Kelseyand William A. Dayton, with assistance from the U.S. Dept.of Agriculture, for the American Joint Committee on Horti-cultural Nomenclature. 1942.

Other sources used in selecting common names include:A Manual of Higher Plants of Oregon, 2nd Edition. Morton

E. Peck.Manual of Grasses of the United States, 2nd Edition. A.S.

Hitchcock, revised by Agnes Chase.Manual of Flowering Plants of California. Willis Linn Jepson.Key to Important Woody Plants in Eastern Oregon and

Washington. Doris W. Hayes and George A. Garrison.Flora of Southeastern Washington and of Adjacent Idaho.

Harold St. John.A list of common names compiled in 1969 by the senior

-author with contributions from some "old-timers": (1)Maxwell Lieurance and others in Bureau of Land Man-agement; (2) Charles Waldron and others in U.S. ForestService; (3) Harry Wegeleben, Claude Dillon, FredGreenfield and Eugene Hickman in Soil ConservationService.

Appendices

An appendix of old-time common names applied toNorthwest plants follows the Check List. These nameswere obtained from the Range Plant Handbook which waspublished by the U.S. Forest Service in 1937. Many ofthese names likely originated in other regions.

An appendix of scientific names (genera) that occur inthe Common-name Check List is included for those whowish to look up the common name(s) of a species. Pagenumber(s) following each genera indicate the page(s) onwhich that genera occurs.
