Species Duvernoia trichocalyx

For Johann Georg Duvernoy (1692–1759), German professor of anatomy and surgery, and a botanist. A student in Paris (1708) of Joseph Pitton de Tournefort (who formulated the concept of genus), he established that certain large bones found in Siberia belonged to the mammoth, not the elephant, and was the author of Designatio Plantarum Circa Tubingensem Arcem Florentium (1722) about the native flora of the Tübingen area.
