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 FLORISTIC PROVINCE divides each state into more or less "natural" regions, defined by factors such as climate, topography, soils and resultant vegetation types. Unique combinations of these factors are sometimes reflected in locally high levels of endemism. This character may have considerable value in separating otherwise similar taxa when used with caution.
