Hi Sally

The simplest definition I could give (without going into detail of
representation) would be a scientific name as defined in a particular
For example,
Utricularia foliosa L. 
As defined in:
Taylor, P. 1989. The Genus Urticularia: A Taxonomic Monograph. Kew
Bulletin Additional Series XIV. Royal Botanic Gardens, Kew. London.  

The important issue being that the name is directly associated to at
least one and only one definition i.e. that where it was defined -
unless of course the database is capturing a new(revised) definition of
a concept in which case I would hope that it contain a good unambiguous
description of the concept as they see it - otherwise they should refer
to a defined concept they agree with)
