Phrase name

In Australian botany, a phrase name is an informal name given to a plant taxon that has not yet been given a formal scientific name. The term was adopted in 1992 by the Australian Herbarium Information Systems Committee. The species phrase name consists of four components — the generic name, "sp." (to indicate it is a species), an identifier (geographical or morphological) and a collector’s name and number representing a herbarium specimen vouchering the concept of the new species.
