4. Challenges in creating a modern Southeastern floristic atlas 1. Regional floras are generally obsolete and incomplete. 2. Local atlases follow idiosyncratic taxonomies. 3. Few museum collections have been databased. 4. Museum collections are rarely determined to concept. 5. Floristic lists and ecological datasets with multiple taxonomic authorities and inconsistent taxonomic concepts have defied integration.

10. The good news: Multiple organizations are developing tools for concept use and integration. Multiple organizations are developing tools for concept use and integration. The challenge: Few large-scale compilations of concepts and their relationships are available. Few large-scale compilations of concepts and their relationships are available.

15. Toward a new Atlas Carya carolinae-septentrionalis, Radford et al. 1968 How to integrate new sources of data?? http://herbarium.unc.edu/seflora/firstviewer.htm

16. Add dynamic access to NCU collection Carya carolinae-septentrionalis NCURAB

17. NCURABUSDACVS Add USDA PLANTS records & CVS vegetation plot data

18. But wait !! There is a concept issue According to Radford 1968, USDA PLANTS v 4.0, & Weakley 2005According to Radford 1968, USDA PLANTS v 4.0, & Weakley 2005 –Carya carolinae-septentrionalis –Carya ovata According to Stone 1997 in FNAAccording to Stone 1997 in FNA –Carya ovata var australis –Carya ovata var. ovata

20. Carya carolinae-septentrionalis Some nominal occurrences might or might not represent the taxon

21. All specimens of Carya ovata must be identified to nominal concepts

22. Consider Cleistes Cleistes bifaria was split off C. divaricata after Radford et al. was published.Cleistes bifaria was split off C. divaricata after Radford et al. was published. Radford et al. records must be mapped as ambiguous.Radford et al. records must be mapped as ambiguous. Kartesz incorrectly maps all Cleistes in the Carolinas as C. divaricata owing to uncritical import of records from Radford.Kartesz incorrectly maps all Cleistes in the Carolinas as C. divaricata owing to uncritical import of records from Radford.
