Philosophia botanica in qua explicantur fundamenta botanica cum definitionibus partium, exemplis terminorum, observationibus rariorum, adjectis figuris aeneis.

This work was "the first textbook of descriptive systematic botany and botanical Latin".^[1] It also contains Linnaeus's first published description of his binomial nomenclature.

"Philosophia Botanica represents a maturing of Linnaeus's thinking on botany and its theoretical foundations, being an elaboration of ideas first published in his Fundamenta Botanica (1736) and Critica Botanica (1737), and set out in a similar way as a series of stark and uncompromising principles (aphorismen). The book also establishes a basic botanical terminology" (Wikipedia article Philosophia Botanica, accessed 3-2020).
