Abstract:

This report represents the beginning of an effort to keep accurate records of the endangered and threatened plant species of the United States. We are, however, mindful of the fact that the status of plants on the lists will change and that the lists, accordingly, should be revised on a regular basis. Scientific names, which include genus, species, subspecies, and varieties, are used in this report because common names are not available for many of the plants, particularly the rarer or lesser known ones. In addition, the use of common names may cause confusion because they frequently refer to an entire group of species, or even to different and unrelated genera. Moreover, the same species of plants may have different local names in different geographical regions. It is the hope of botanists that an attempt will be made someday to standardize the common names of plants. The report and the lists will, we hope, be of value to all people interested in conserving the nation's biological heritage, and to those concerned with the exploitation, development, management, and preservation of all natural resources in this country.
