Unknown rank Acacia nilotica subsp. kraussiana

For Christian Ferdinand Friedrich von Krauss (1812–90), German naturalist, explorer and collector. In 1838, Krauss, an apothecary with a PhD in mineralogy, zoology and chemistry from Tübingen and Heidelberg (1836), sailed for the Cape. Here, he collected many specimens, especially molluscs and crustaceans, but also made a study of the geology, flora and fauna. From 1838–1839 he explored the areas between Cape Town and Port Elizabeth and in 1840 the bush and seashore around the Congella River, Pietermaritzburg. He left to join the Natural History Museum, Stuttgart, in 1940, becoming its director in 1956. He wrote Die Südafrikanischen Crusaceen (1843) and Die Südafrikanischen Mollusken (1848).
