Rules 12d, 12e, 1 2f. Sect. 3. Publication of Names 



RULE 12d. A name of a taxon is not validly published when it is merely 

 cited as a synonym. 



RULE 12e. The name of a taxon is not validly published by the mere mention 

 of the subordinate taxa included in it. 



RULE 12f. The date of a name or of an epithet is that of its valid publica- 

 tion. For purposes of priority, hov/ever, only legitimate names and epithets 

 published in legitimate combinations are taken into consideration. In the 

 absence of proof to the contrary, the date given to the work containing the 

 name or epithet must be regarded as correct. 



ANNOTATIONS 



Rule 12d. Trevisan {Rendiconti Real. 1st. Lombard, d. Sci. e Lett., 

 Ser. 2, 1879, 72:144) cited Malleomyces equestris Hallier as a synonym 

 of Micrococcus equestris which he regarded as the causal organism of 

 glanders. Inasmuch as all of Hallier's species were based upon mixed 

 cultures and his names, therefore, illegitimate (see Rule 24g) , this 

 incidental citation as a synonym by Trevisan does not validate the 

 name. Malleoyyiyces must date as a generic name from its proposal 

 by Pribram in 1933 {Klassification des Schizomyceten, p. 93) . 

 Rule 12f. Chondromyces crocatus Berkeley and Curtis 1857 (in 

 Berkeley, Introduction to Cryptoga^nic Botany, p. 313) is a name 

 appended to an illustration without description. The description 

 was published later (Berkely, Grevillea, 1874, 5:64) and valid publi- 

 cation was of the latter date.
