Franz von Fleischer (27 November 1801, in Lausick – 24 August 1878, in Hohenheim) was a German botanist.
In 1825 he undertook a botanical study trip to the Alps, followed by an extended scientific expedition in 1826/27 that took him to Illyria, Istria, Greece, Asia Minor, Syria and Egypt.
The collections were partly distributed by the German scientific society Unio Itineraria as exsiccata-like series.
[1][2] Afterwards, he studied medicine and natural sciences at the University of Tübingen, and following graduation in 1832, he worked as a teacher of natural sciences at the Hofwyl agricultural school in the canton of Bern.
[3][4] From 1834 to 1840 he taught classes in natural sciences at the cantonal school in Aarau, and afterwards, served as a professor at the Agricultural Academy in Hohenheim.
