Flora Japonica (1834 book)

Flora Japonica is a Flora written in Leyden by Bavarian botanist and traveler Philipp Franz von Siebold in collaboration with fellow Bavarian Joseph Gerhard Zuccarini. The work, written in Latin, carries the full title of Flora Japonica; sive, Plantae Quas in Imperio Japonico Collegit, Descripsit, ex Parte in Ipsis Locis Pingendas Curavit..

Begun in 1835 by Siebold and Zuccarini, work continued until 1842. After Zuccarini's death in 1848, Siebold discontinued his involvement with the work, and the materials accrued to Rijksherbarium [nl; de] in Leyden. After Siebold's death in 1866, F. A. W. Miquel, director of the Rijksherbarium, completed the work.

Siebold was already widely known in Japan for various endeavors, and this work cemented his scientific fame in Europe.
