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, 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 (1982) except as modified by State distribution data from an unpublished plant 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 0). 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, RIIND, R2IND, R3IND, R4IND, R5IND, R6IND, R7IND, 

 R8IND, R9IND, ROIND, RAINO, RCIND, RHINO, and REGION. The National trinomial 

 list is reported by SCI-NAME, TRINOM, RIIND, R2IND, R3IN0, R4IND, R5IND, R6IND, 

 R7IN0, R8IN0, 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 SCI -NAME, AUTHOR, COMMON-NAME, R_IND, NAT-IND, and HABIT. 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 fonts (HABIT) by COMMON-NAME, RJND, NAT-IND, SYMBOL, SCI-NAME, and 

 HABIT. 



The information in these lists is presented in the following categories. A brief 

 definition of the categories reported in the various lists is given below:
