Philosophia Botanica (The Science of Botany), by Carl Linnaeus, was originally published in Latin in Stockholm and Amsterdam in 1751. It is a greatly expanded revision of his Fundamenta Botanica (Foundations of Botany) of 1736, summarizing his work on the classification and taxonomy of plants while adding substantial new material. The book represents a critical stage in the evolution of binomial nomenclature, with a single word to describe the genus and another for the species.
