At age 23, the German Carl Friedrich Philipp von Martius was chosen by the Austrian Emperor, Franz I,
as one of the members of an entourage,
which would accompany the Archduchess Leopoldine to Brazil.
The Archduchess was recently married to the Brazilian Emperor, Pedro I,
and the scientific expedition to be embarked upon by these naturalists
was a part of her dowry.
The goal of the expedition was to spend two years collecting specimens
and documenting the natural history of
Brazil.
He travelled in Brazil for three years, accompanied by the zoologist Johann Baptist von Spix,
covering c. 10,000 km between
Rio de Janeiro
and the upper
Amazon,
on horseback, on foot or in a canoe.
Martius collected c. 20,000 specimens of plants and dedicated the rest of his life to his
Brazilian botanical collections.
He edited the first volumes until his death in 1868, when it was continued by August Eichler, and finally
completed by Ignatius Urban in 1906.
Flora Brasiliensis is still the only complete Flora of Brazil and remains the primary
reference for botanists working in Brazil.
