Thilo Irmisch (1816 - 1816)

Johann Friedrich Thilo Irmisch (14 January 1816 in Sondershausen – 28 April 1879) was a 19th century German botanist. Two plant genera were named to his honour. His friend and former teacher von Schlechtendal named the genus Irmischia, which was soon synonymized with Metastelma (Apocynaceae). August Eichler then named the genus Thiloa (Combretaceae) for Thilo Irmisch.
