November 1, 1783
Today is the anniversary of the death of Carl Linnaeus.
Thirty years earlier, on May 1st, 1753, the publication of his masterpiece Species Plantarum changed plant taxonomy forever.
Linnaeus earned the moniker Father of Taxonomy; his naming system is called binomial nomenclature. Binomial means "two names," which in the naming game includes the plant's genus (which is capitalized or could be abbreviated by its first letter) and species or specific epithet (which is all lowercase and can be abbreviated sp.) If you have trouble remembering taxonomy, I like to think of it as the given name and surname of a person, but in reverse order.
The names Linnaeus assigned live on unchanged and are distinguished by an “L.” after their name. And, it was Linnaeus himself who said:
“God created, Linnaeus ordered.”
