German botanist (1843–1907).
Carl Ernst Otto Kuntze (23 June 1843 – 27 January 1907) was a German businessman and botanist. He went on a round-the-world plant collecting trip from 1874 to 1876 making extensive collections from South America and Asia. His major contribution was a three volume revision of plant genera Revisio Generum Plantarum (1891). This revision troubled many botanists because of the changes he suggested to nearly 30000 taxa, many which were contrary to the rules established by the botanical congress of 1867. This however forced botanists to make reforms to the botanical code.
