How did Carolus Linnaeus use international contacts to improve the Uppsala botanical garden?

Carolus Linnaeus utilized his international contacts to establish a global network of correspondents who provided him with a steady supply of seeds and specimens from around the world. He incorporated these materials into the botanical garden at Uppsala University, which allowed him to develop and refine the empirical basis for his major taxonomic works, including Species Plantarum.1

Additionally, Linnaeus expanded the garden's collection by sending his students, known as the "Linnaean apostles," on expeditions across the globe to collect exotic plants for acclimatization in Sweden. These efforts were part of his broader commitment to scientific administration and the betterment of his home country.2
