The rules of botanical nomenclature
Published online by Cambridge University Press: 03 December 2009
Summary
The rules which now govern the naming and the names of plants really had their beginnings in the views of Augustin P. de Candolle as he expressed them in his Théorie élémentaire de la botanique (1813). There, he advised that plants should have names in Latin (or Latin form but not compounded from different languages), formed according to the rules of Latin grammar and subject to the right of priority for the name given by the discoverer or the first describer. This advice was found inadequate and, in 1862, the International Botanical Congress in London adopted control over agreements on nomenclature. Alphonse Louise de Candolle (1806–1893) drew up four simple ‘Lois’, or laws, which were aimed at resolving what threatened to become a chaotic state of plant nomenclature. The Paris International Botanical Congress of 1867 adopted the Lois, which were:
One plant species shall have no more than one name.
No two plant species shall share the same name.
If a plant has two names, the name which is valid shall be that which was the earliest one to be published after 1753.
The author's name shall be cited, after the name of the plant, in order to establish the sense in which the name is used and its priority over other names.
