Chresonym

The term is derived from the Greek χρῆσις chresis meaning "a use"[1] and refers to published usage of a name.

The technical meaning of the related term synonym is for different names that refer to the same object or concept.

As an example, the sperm whale, Physeter catodon, was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae.

That name was also used by Harmer in 1928 to refer to the species in the Proceedings of the Linnean Society of London and of course, it has appeared in numerous other publications since then.

Cheek and Jebb (2001)[6] explain the situation thus: Low, ... accidentally, or otherwise, had described what we know as N. rafflesiana as Nepenthes × hookeriana and vice versa in his book "Sarawak, its Inhabitants and Productions" (1848).
