Due to my work, I regularly consult databases such as The Plant List, Euro Med Plant, Catalogue of Life, and many other references. I understand the complexity of botanical nomenclature, but sometimes I find astonishing cases like Buchloe dactyloides (Nutt.) Engelm.
TPL gives this name with full guarantee:
http://www.theplantlist.org/tpl1.1/record/kew-402269
So does Catalogue of Life:
http://www.catalogueoflife.org/col/details/species/id/9784486
Otherwise, in some databases I find that the accepted name is Bouteloua dactyloides (Nutt.) Columbus:
USDA: http://plants.usda.gov/factsheet/pdf/fs_buda.pdf
http://plants.usda.gov/core/profile?symbol=boda2
Euro Med Plant:
http://ww2.bgbm.org/EuroPlusMed/PTaxonDetail.asp?NameCache=Bouteloua%20dactyloides&PTRefFk=7100000
However, the reference given by TPL and Catalogue of life is the same, and the name accepted is Bouteloua: Checklist of Selected Plant Worls families (Kew databases)
http://apps.kew.org/wcsp/synonomy.do;jsessionid=21AA288BDF14E0E3C7099DEABF3CC374?name_id=399423
This potential error can be trasferred to successive databases if we don't check the original source before .
I would greatly appreciate your point of view, both in the particular case of Buchloe as well as your general comments.
