COMPOSITION OF THE LISTS 



The National, regional, and State lists are reported in a variety 

 of formats. All of the lists are initially arranged alphabetically 

 by scientific name followed by a second list, also alphabetical by 

 scientific name, of those species with infra-specific (subspecies, 

 variety, or form) Indicator assignments. A third list, alphabetic 

 by scientific name, provides a list of synonyms related to the 

 equivalent accepted name shown in the alphabetical scientific name 

 list. The State lists also contain a fourth compilation, following 

 the synonymy report, of the species found in each State, 

 alphabetized by common name and subdivided into eight separate 

 lists by life form (trees, shrubs, woody vines, forbs, grasses, 

 grasslikes [sedges and rushes], ferns and allies, and aquatics). 



Nomenclature and distribution follow the National List of 

 Scientific Plant Names (1982) except as modified by State 

 distribution data from an unpublished plant species geographic data 

 base (Kartesz) . 



Epiphytic (e.g., mistletoes and some orchids) and nonrooted species 

 (e.g., dodder) were excluded from the National List because their 

 roots were respectively either never exposed to ground-level soil 

 conditions or were not in existence during all or part of the 

 plant's life span. The current National List contains only 

 vascular plants, but a companion list of Bryophytes (mosses and 

 liverworts) that occur in wetlands is being developed to further 

 define the wetland flora of the United States. The Algae have also 

 been excluded from the current list. 



Listings of the members of the National and appropriate Regional 

 Interagency Review Panels and the regional reviewers are included 

 at the end of each list (Appendix D) . Not all categories listed 

 below are displayed in each National, regional, or State report. 

 The National alphabetical scientific name list is reported by 

 SCI-NAME, NAT-IND, R1IND, R2IND, R3IND, R4IND, R5IND, R6IND, R7IND, 

 R8IND, R9IND, ROIND, RAIND, RCIND, RHIND, and REGION. The National 

 trinomial list is reported by SCI-NAME, TRINOM, R1IND, R2IND, 

 R3IND, R4IND, R5IND, R6IND, R7IND, R8IND, R9IND, ROIND, RAIND, 

 RCIND, RHIND, and REGION. The National, regional, and State 

 synonym lists are reported by SYNONYMY, SCI-NAME, AUTHOR, and 

 REGION. The regional and State alphabetical scientific name lists 

 are reported by NAT-IND, R_IND, GENUS-SPECIES-AUTHOR, COMMON NAME, 

 HABIT and REGION. The regional and State trinomial lists are 

 reported by SCI-NAME, AUTHOR, TRINOM, R_IND, NAT-IND, and HABIT. 

 The State alphabetical common-name lists are reported within life 

 forms (HABIT) by NAT-IND, R_IND, COMMON NAME, SYMBOL, GENUS- 

 SPECIES-AUTHOR, and HABIT.
