The Herbarium 



NOMENCLATURE 



When anyone for the first time refers a newly discovered 

 species to a genus, he gives the species a specific name and 

 appends his own name or an abbreviation of it as the authority, 

 thus, Bryum argenteum, L. means that Linnaeus referred a species 

 to Bryum and gave it the specific name argenteum and that his 

 classification has not been changed. 



If a plant has been referred by one man to a certain genus 

 that later is proved by another man to belong to a different genus, 

 the name or abbreviation of the first author is placed in paren- 

 thesis and followed by that of the second author thus: Rama Una 

 ceruchis (Ach.) De Not., means that De Notaris placed the species 

 ceruchis in its proper genus Ramalina after Acharius had placed 

 it in another genus (Borrera).
