Description:
SCI_NAME (Scientific Name)
   The genus and species applied to the taxon by the National List of
   Scientific Plant Names (1982).

AUTHOR
   The author of the scientific name as cited by the National List of
   Scientific Plant Names (1982)

C_NAME (Common Name)
   A popular name applied to the species. Common name selection generally
   follows Common Names for North American Plants (Kartesz and Thieret, in
   press), but some common names follow current common name list maintained by
   the Soil Conservation Service).

NAT_IND (National Range Of Indicators)
   The National Indicators reflect the range of estimated probabilities
   (expressed as a frequency of occurrence) of a species occurring in wetlands
   versus non wetland across the entire distribution of the species. A
   frequency, for example, of 67%-99% (Facultative Wetland) means that 67%-99%
   of sample plots containing the species randomly selected across the range
   of the species would be wetland. A question mark (?) following an Indicator
   denotes a tentative assignment based on the botanical literature and not
   confirmed by regional review. When two indicators are given, they reflect
   the range from the lowest to the highest frequency of occurrence in
   wetlands across the regions in which the species is found. A positive (+)
   or negative (-) sign was used with the Facultative Indicator categories to
   more specifically define the regional frequency of occurrence in wetlands.
   The positive sign indicates a frequency toward the higher end of the
   category (more frequently found in wetlands), and a negative sign indicates
   a frequency toward the lower end of the  category (less frequently found in
   wetlands).

   Indicator categories:
   Obligate Wetland (OBL).   Occur almost always (estimated probability >99%)
   under natural conditions in wetlands.
   
   Facultative Wetland (FACW).   Usually occur in wetlands (estimated
   probability 67%-99%), but occasionally found in non wetlands.

   Facultative (FAC).   Equally likely to occur in wetlands or non wetlands
   (estimated probability 34%-66%).

   Facultative Upland (FACU).   Usually occur in non wetlands (estimated
   probability 67%-99%), but occasionally found on wetlands (estimated
   probability 1%-33%).

   Obligate Upland (UPL).   Occur in wetlands in another region, but occur
   almost always (estimated probability >99%)under natural conditions in non
   wetlands on the region specified. If a species does not occur in wetlands
   in any region, it is not on the National List.
   
   The wetland Indicator categories should not be equated to degrees of
   wetness. Many obligate wetland species occur in permanently or
   semipermanently flooded wetlands, but a number if obligates also occur and
   some are restricted to wetlands which are only temporarily or seasonally
   flooded. The facultative upland species include a diverse collection of
   plants which range from weedy species adapted to exist in a number of
   environmentally stressful or disturbed sites (including wetlands) to
   species in which a portion of the gene pool (an ecotype) always occurs in
   wetlands. Both the weedy and ecotype representatives of the facultative
   upland category occur in seasonally and semipermanently flooded wetlands.

R_IND (Regional Indicator)
   The estimated probability (likelihood) of a species occurring in wetlands
   versus non wetlands in the region. Regional Indicators reflect the
   unanimous agreement of the Regional Interagency Review Panel. If a regional
   panel was not able to reach a unanimous decision on a species, NA (no
   agreement) was recorded on the regional indicator (R_IND) field. An NI (no
   indicator) was recorded for those species for which insufficient
   information was available to determine an indicator status. A nonoccurrence
   (NO)designation indicates that the species does not occur in that region,
   An asterisk (*) following a regional Indicator identifies tentative
   assignments based on limited information from which to determine the
   indicator status. In the listings for the States divided into two regions
   (Montana, Wyoming, and Colorado), both regional Indicators are reported.

HABIT
   The plant characteristics and life forms assigned to each species in the
   National List of Scientific Plant Names (1982) and by the Soil Conservation
   Service. Family names are listed alphabetically under specific life forms
   restricted to these families. The HABIT symbols are combined to describe
   the life form of the species (e.g., ANG means annual native grass, IT means
   introduced tree).
