Elemens de botanique, ou methode pour connoître les plantes.

Though Tournefort's classification was completely artificial, and neglected some important divisions established by earlier botanists, and was a step backwards in systematics, the text was so clearly written and well structured, and contained so much valuable information on individual species, that it became popular amongst botanists, and nearly all classifications published for the next fifty years were based upon it.

"Tournefort is often credited with being the first to make a clear distinction between genus and species. Though he did indeed cluster the 7,000 plant species that he described into around 700 genera, this was not particularly original. Concepts of genus and species had been framed as early as the 16th century, and Kaspar Bauhin in particular consistently distinguished genera and species. Augustus Quirinus Rivinus had even advocated the use of binary nomenclature shortly before Tournefort's work was published.^[2] (Wikipedia article on Joseph Pitton de Tournefort, accessed 3-2020).
