“…Tafalla and Manzanilla collected plants in the Loja region, and their works on Cinchona were included in the publications of Ruiz and Pavón, and in the Nueva Quinología of Pavón [28][29][30]. Their Cinchona collections are held in the Real Jardín Botánico and Kew Gardens and share similar histories [31].…”

The Cinchona genus is important for humanity due to its ethnobotanical properties, and in particular its ability to prevent and treat malaria. However, there have been historical changes of Cinchona distribution in the tropical Andes that remain undocumented. In the late eighteenth and early nineteenth centuries, several explorers recorded Cinchona precise localities in present-day Colombia and Ecuador, countries which harbour about half of the species of the genus, including C. officinalis . We compare historical and twentieth-century records to evaluate whether elevational ranges, mean elevation and latitude varied between the two periods. A large expansion of 662.5 m in average elevation for Cinchona and 792.5 m in elevational range for C. officinalis was found. These findings have implications for the conservation of economically important species and help us understand the impacts of the Anthropocene over time.

The Royal Spanish Botanical Expedition to the Viceroyalty of Peru in the 18th century was one of the most important European expeditions to American territories. Using the herbarium sheets of Ruiz and Pavón (Royal Botanical Garden of Madrid) and their edited works, manuscripts and expedition diaries, we have constructed a database of the collected and observed flora, which has served as the basis for a map containing all of the Peruvian localities of the expedition. Based on the method of bioclimatic belts and our own observations, we have deduced to which type of vegetation the flora studied in the expedition belongs. The uses of the flora per locality were studied, as well as the ethnic groups involved in the different localities. By using a Principal Component Analysis, we have obtained the distribution of the bioclimatic belts whose vegetation was the most explored. In order to observe the bioclimatic tendency of plant uses, a Detrended Correspondence Analysis (DCA) was conducted to identify the distribution of localities with the highest frequencies of plant uses. The expedition’s explorations focused on the most humid areas of the thermo- and mesotropical belts, from where a large number of plants with practical uses were obtained.
