Notes: The name Duggena Vahl (in H. West) has sometimes been cited as an older name for Gonzalagunia, but is not. The name Duggena Vahl did first appear in print in 1793 before the name Gonzalagunia was published in 1794. However the citation there of Duggena did not meet the current criteria for valid publication of plant names, because this citation comprised only the a new name, Duggena richardii Vahl, given there to replaced Justicia hirsuta Jacq. The genus name Duggena had not been separately published or described beyond this citation, and a genus cannot be validated only by reference to a previously published species. Thus Gonzalagunia is the oldest validly published name for this genus. Later, in 1916, Standley found and used the name Duggena but its valid publication only dates from his works, long after the publication of Gonzalagunia.
