Karl Richter (16 May 1855 in Vienna - 28 December 1891 in Vienna) was a botanist from Austria-Hungary.
From 1874 he studied botany at the University of Vienna, where he received his doctorate in 1877. After completing his studies at the university he worked as a private scholar in Vienna.[1] His herbarium was acquired by Eugen von Halácsy, who incorporated it into his own herbarium, which was later donated to the University of Vienna.[2]
With Max Gürke, he was co-author of Plantae Europaeae (1890–1903).[3] In 1885 he published Die botanische Systematik und ihr Verhältniss zur Anatomie und Physiologie der Pflanzen (Botanical systematics and its relationship to the anatomy and physiology of plants).[4]
