In 1735 the young botanist, Carl Linneaus, published System Naturae, and with its publication, modern botany was born. Originally 11 pages long, he worked on the publication throughout his lifetime. The final, 13th edition was published in 1770 and was over 3,000 pages long.
As a busy collector, Linneaus needed a better, simpler way to identify his specimens. Prior to his work, plants were given long, descriptive Latin names and each name was like a new, unrelated discovery. After completing two expeditions collecting specimens, he was the first to drop the lengthy descriptions and to consistently use two simple words to identify his specimens. He had studied the work of botanists before him, including their naming systems, and had collected, identified, discovered, and thought about so many species that he was beginning to see order where those before him had not. One area he focused on was the flowers of his specimens and he began grouping specimens by the arrangement of their reproductive parts — by counting the numbers of stamens and pistils.
