Franz Kohaut (died 1822) was a Czech botanical collector and gardener from Neuhaus, Bohemia.
In 1816–18 he accompanied botanist Franz Wilhelm Sieber (1789–1844) on an expedition and collected together with him plant material for exsiccata-like series in Crete, [1] Egypt [2] and Palestine. [3] Afterwards Kohaut worked for Sieber as a botanical collector in Martinique (1819–21). Specimens from Martinique were later distributed by Sieber as Herbarium florae Martinicae (Plantae insulae Martinica) and Supplement. [4] [5] Kohaut died in 1822 while together with J. Schmidt on an expedition in Senegal. His material from this expedition was distributed by F. Sieber under the title Flora Senegalensis. [6] Specimens collected by F. Kohaut are deposited now in a number of herbaria.
The plant genus " Kohautia " from the family Rubiaceae is named in his honor, as well as the species "Tetrapteris kohauti" Sieber ex Presl (Malpighiaceae) and " Cestrum kohauti" Bercht. & J.Presl (Solanaceae). [7]
