 | | In the database, the period of use of a name is indicated independently of its taxonomic status; it is not an evaluation of the nomenclatural status but an item of information to be used with some caution. |
 | | For a discussion of the terms relevant to interpretation of nomenclatural and taxonomical information (such as sanctioning, periods of name usage, and taxonomically correct names), the user is referred to Parmasto (1997). |
 | | In addition to providing information on basionym and taxonomically correct name, it also lists all homotypic and heterotypic synonyms, including data on type, sanctioning, time periods for name usage, and nomenclatural status (validly published or not, legitimate or not). |
