Details

concept: GermanSL is a list with a single taxon view according to the standard lists of the different taxon groups (e.g Wisskirchen and Haeupler for higher plants, see). Nevertheless a huge number of synonyms is included which allows in many cases the transformation into different concepts. For illustration the concept of Armeria maritima from Korneck 1996 is included, which accepts e.g. Armeria maritima ssp. bottendorfensis. parse.taxa: parse genus and epitheta from name strings. taxname.removeAuthors Remove name authors from full scientific name strings.
