Paul Friedrich August Ascherson

Paul Friedrich August Ascherson (June 4, 1834 – March 6, 1913) was a German botanist. His author citation is Asch., although Aschers. has been used in the past.

Ascherson was born in Berlin in 1834 as the son of a counsellor of health. In 1850, he started studying medicine at the University of Berlin, but soon started getting more interested in botany. In 1855, he received his doctorate for a dissertation about the flora of the Margraviate of Brandenburg. In the 1850s, he started to botanize in Saxony, including several excursions with Ludwig Schneider and Gustav Maass. In 1860, Ascherson became an assistant at the Botanical Garden in Berlin, in 1865 he also started working at the Royal Herbarium. In 1863, he obtained his habilitation for specific botany and plant geography. In 1873, Ascherson became associate professor at the University of Berlin. He accompanied Friedrich Gerhard Rohlfs on his 1873/74 expedition in the Libyan desert. After 1876, he went on further expeditions in Africa, publishing fundamental works about the flora of the continent. In the 1890s he botanized in Jerichower Land and in the Vorharz along with Paul Graebner.

Ascherson is known for combining works about the flora in certain localities with his own observations to write descriptions of the flora of a larger territory. He was also an entomologist. Insect collections made by him in Africa are conserved in Museum für Naturkunde in Berlin.[1]
