Anderson (1993) proposed Gaudichaudieae (A. Juss.) W. R. Anderson with the aim to “ validate ” the name published by Jussieu (1840). Nonetheless, the name published by Jussieu (1840) was proposed as unranked and was not validly published until Morton (1968) provided a Latin diagnosis while also correcting its spelling and rank to be used as a subfamily. However, both authors overlooked that the name had already been validly published as a tribe, accompanied by a Latin diagnosis by Horaninow (1847). Therefore, Anderson’s name is a superfluous, later homonym of Gaudichaudieae Horan.
