João de Loureiro (1717, Lisbon – 18 October 1791) was a Portuguese Jesuit missionary and botanist. [1]

Biography[edit]

After receiving admission to the Jesuit Order, João de Loureiro served as a missionary in Goa, capital of Portuguese India (3 years) and Macau (4 years). In 1742 he traveled to Cochinchina, remaining there for 35 years. Here he worked as a mathematician and naturalist for the king of Cochinchina[2], acquiring knowledge on the properties and uses of native medicinal plants. In 1777, he journeyed to Canton, in Bengal, returning to Lisbon four years later.[3] During this period, the Captain Thomas Riddel gave Loureiro the books Systema Naturae, Genera Plantarum and Philosophia Botanica by Carl Linnaeus, which greatly influenced the Portuguese botanist.[4]

The first 40 years he stayed in Vietnam, João de Loureiro was inventorying indigenus herbal remedies. His local garden contained 1,000 unique herbal species, making him one of the greatest botanist collectors of the XVIIIth century.[2]

João de Loureiro 1790, he published the book Flora Cochinchinensis sponsored by the Royal Portuguese Academy of Sciences.[4] João de Loureiro has numerous species "loureiroi" dedicated to him, mostly plants but also the dinosaur Draconyx loureiroi in honour of his being the first Portuguese palaeontologist.[5]

The taxonomist Elmer Drew Merrill later argued that Loureiro's work contained various mistakes caused by a misunderstanding of the Linnaean system.[4]
