José Mariano da Conceição Velloso

Born in Minas Gerais in 1742 and dying in Rio de Janeiro in 1811, José Mariano da Conceição Velloso was a Brazilian colonial priest, teacher, missionary, and botanist. He is remembered above all for his work studying and describing Brazilian plants, at a time when that kind of large-scale botanical documentation was still taking shape.

His name is closely linked to Flora Fluminensis, the major botanical project for which he became best known. The work described a large number of plants from the region around Rio de Janeiro and helped preserve scientific knowledge about Brazilian flora for later generations.

Velloso also wrote on practical subjects connected to agriculture and natural history, showing an interest not only in classification but in how knowledge could be used. That mix of religious life, scientific curiosity, and useful writing has made him an important figure in the history of botany in Brazil.
