关于Journal of Ethnopharmacology里面的authorities (not italics)

最近投稿Journal of Ethnopharmacology，编辑发过来这么一段话：

Full botanical plant names (italics), including authorities (not italics), must be provided at first mention in the main text for all botanical components in the polyherbal formulation. Please check also if your plant name corresponds to the latest revision in “The Plant List” (www.theplantlist.org) or MPNS ( http://mpns.kew.org). In the text it should be stated that the plant name has been checked with http://www.theplantlist.org mentioning the data of accessing that website.

Please use the correct nomenclature format: full botanical plant names (italics), including authorities (not italics), must be provided.

我已经返修回去一次了，已经提供了full botanical plant names (italics)，但是编辑一天后又给我发了这个邮件，可能是因为没有提供authorities (not italics)，有大神知道这个啥意思吗？怎么去找啊？我看了以前文献，也没有这个东西啊？
