The area of floristics is one of the most important subfields of botany. This gaggle of researchers focuses only on those botanists who published significant floras or contributions of floras at and above the level of nation, state, province or large region. With a few notable exceptions, we have excluded botanists who published only local floristic studies, such as county floras in the U.S., because of the sheer number of botanists who participated in such studies. We have also excluded botanists who contributed to floras, but were mostly specialists in particular groups or families. |
