Abstract

This paper provides a translation of the introduction, titled ‘Account of the work’ Ratio operis, to the first edition of Genera plantarum, published in 1737 by the Swedish botanist Carl Linnaeus. The text derives its significance from the fact that it is the only published text in which Linnaeus engaged in an explicit discussion of his taxonomic method. Most importantly, it shows that Linnaeus was clearly aware that a classification of what he called ‘natural genera’ could not be achieved by a top-down approach of logical division, but had to rely on inductive, bottom-up procedures. The translation is supplemented by explanatory notes.
