Distribution by state
The locality where the specimen was found naturally and excludes cultivated specimens. Distribution can be very valuable in identifying specimens, but should be treated cautiously, as our knowledge of taxon distributional ranges is generally limited. Many distributions could be extended as sampling increases. Users should seek additional correlating characters when an identification is ultimately based on distribution.
DISTRIBUTION BY STATE is easily interpreted, but can have little or no biological reality. Most states include 2 or more biogeographical regions, and with the exception of the South-West (WA) Botanical Province, each biogeographical region extends through 2 or more states. There is likely to be a risk of artificially eliminating taxa due to inadequate distributional sampling.
