Which book of Carolus Linnaeus is considered the bible or foundational text of taxonomy containing compiled nomenclature rules?

Correct answer: Philosophia Botanica

Answer: A, Philosophia Botanica. Linnaeus published this work in 1751, and it presented important principles of botanical description and the use of binomial names. It is therefore treated as a foundational work for the rules and ideas of modern taxonomy. Systema Naturae was highly important for presenting a broad system of classification, but it is not the best answer to this particular question about the compiled principles of nomenclature. Species Plantarum is especially associated with the naming and description of plant species, while Genera Plantarum dealt mainly with plant genera. Thus, the wording about principles and rules points to Philosophia Botanica. A useful memory cue is: Philosophia Botanica explains the philosophy and principles behind botanical naming; Systema Naturae presents a larger classification framework.
