CHARLES LINNAEUS The great botanist who gave his name and surname to plants Linnaeus immediately demonstrated a remarkable talent in classifying plants. He soon obtained a teaching assistantship, and began to explore in the Swedish countryside and in Lapland. The young scientist immediately began to catalog plants with a system of his own invention. Linnaeus decided that the description of each single species would have two terms: the first referring to the genus, the second to the species. Carl Linnaeus also demonstrated that plants reproduce and gave names to all parts of flowers. He created a taxonomic scheme divided into five categories: variety, species, genus, order and class.
