TaxCat2 - Developing a database of taxonomic categories.
In connection with the
BIG project and the development of a WWW database of
"Mansfeld's World Manual of Agricultural and Horticultural Crops", a survey
of taxonomic categories was started. It quickly turned out that many taxonomic problems
merely arise because of the vast number of categories used to classify taxa [or culta] of
cultivated plants. A lot of terms are used in different meanings by different authors,
others lack exact definitions. As a result it seemed almost impossible to relate all terms
to each other and assign them as far as possible to the terms accepted by the latest
versions of the two Codes (ICBN-1994, Greuter et al. 1994, and ICNCP-1995, Trehane et al.
1995). Forty different taxonomic categories have been accepted by the two actual versions
of the Codes (38 by the ICBN and only two by the ICNCP: cultivar and cultivar-group), but
over 100 categories (without alternative names from other languages) have been found so
far. Many of them have either been accepted by earlier versions of the Codes or have been
used by single authors or in single groups only. In many cases little information on
definition and use is available. This led to the idea to devise a database of taxonomic
categories, where alternative names from different languages as well as synonyms could be
Additionally, some terms from different fields of botany related to botanical nomenclature are recorded (i.e. taxon, culton).
