2. Beginning of Botanical Nomenclature. — The botanical 

 Nomenclature of both genera and species is to begin with the pubhcation 

 of the first edition of Linn^eus's ''Species Plantarum," in 1753. 



3. Stability of Specific Names. — In the transrer of a species 

 to a genus other than the one under which it was first published the 

 original specific name is to be retained, unless it is identical with the 

 generic name or with a specific name previously used in that genus. 



4. Homonyms. — The publication of a generic name or a binomial 

 invalidates the use of the same name for any subsequently published 

 genus or species respectively. 



5. Publication of Gexera. — Publication 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 exunples or types of the genus, 

 with or without a diagnosis. 



6. 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 previ- 

 ously published species as a type. 



7. 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 Apium are to be retained, but 

 of Epidaidruin and Epider.dron, Asterocarpus and Asttocarpus, the 

 later is to he rejected. 



8. 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.
