with the generic name, or with a specific name previously used in 

 that genus. 



IV. Homonyms. — The pubHcation of a generic name or a bi- 

 nomial invalidates the use of the same name for any subsequently 

 published genus or species respectively. 



V. Publication of Genera. — PubHcation of a genus consists 

 only (i) in the distribution of a printed description of the genus 

 named; (2) in the publication of the name of the genus and the 

 citation of one or more previously published species as examples 

 or types of the genus, with or without a diagnosis. 



VI. Publication of Species. — Publication of a species consists 

 only (i) in the distribution of a printed description of the species 

 named; (2) in the publishing of a binomial, with reference to a 

 previously published species as a type. 



VII. Similar Generic Names.— Similar generic names are 

 not to be rejected on account of slight differences, except in the 

 spelling of the same word ; for example Apios and Apiuin are to 

 be retained, but of Epidendnini and Epidcndron, Asterocarpus and 

 Astrocarpus, the latter is to be rejected. 



VIII. Citation of Authorities. — ^In the case of a species 

 which has been transferred from one genus to another, the original 

 author must always be cited in parenthesis, followed by the author 

 of the new binomial.
