Article 55

55.1. A name of a species or subdivision of a genus may be legitimate even if its epithet was originally placed under an illegitimate generic name (see also Art. 22.5).

Ex. 1. Agathophyllum Juss. (1789) is an illegitimate name, being a superfluous substitute for Ravensara Sonn. (1782). Nevertheless
the name A. neesianum Blume (1851) is legitimate. Because Meisner (1864) cited A. neesianum as a synonym of his new Mespilodaphne mauritiana but did not adopt the epithet neesiana, M. mauritiana Meisn. is a superfluous name and hence illegitimate.
