Ludwig Diels
German botanist (1874–1945)

Friedrich Ludwig Emil Diels (24 September 1874 – 30 November 1945) was a German botanist.
Early life
Diels was born in Hamburg, the son of the classical scholar Hermann Alexander Diels. He grew up in Berlin. He studied botany and geography. In 1896 he completed his doctoral thesis on the vegetation of New Zealand. He then became an assistant to Adolf Engler and published several monographs with him.
History
From 1900 to 1902 he travelled together with Ernst Georg Pritzel through South Africa, Java, Australia and New Zealand.
Shortly before the First World War he travelled through New Guinea, and in the 1930s he explored Ecuador. His collections of plants from Australia and Ecuador, which contained numerous holotypes, enriched the knowledge of the concerning floras. His monograph on the Droseraceae from 1906 is still a standard.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
