Carl Friedrich Philipp (Karl Friedrich Philipp) von Martius (17 April 1794 – 13 December 1868) was a German botanist and explorer. Between 1817 and 1820, he travelled 10,000 km through Brazil while collecting botanical specimens. His most important work was a comprehensive flora of Brazil, ''Flora Brasiliensis'', which he initiated in 1840 and was completed posthumously in 1906.
