From 1918 he was assistant curator for palaeobotany at the National Museum of Natural History under Thore Gustaf Halle . In 1931 he received his doctorate in Stockholm ( studies on the tribal history of the Coniferales and Cordaitales ) and became a lecturer at Stockholm University. In 1937 he visited the USA. In 1942 he became professor of botany at Stockholm University. From 1944 to 1964 he was director of the Botanical Garden in Stockholm ( Bergianska trädgården ) and thus bore the title of Professor Bergianus . He was also the editor of their in-house magazine Acta Horti Bergiani . He was also professor of systematic botany at Stockholm University from 1947 to 1962.

From 1931 to 1947 he was secretary of the Committee for Nature Conservation of the Swedish Academy of Sciences and from 1953 to 1957 its president. From 1959 to 1964 he was on the Council of the International Association for Plant Taxonomy, from 1954 to 1959 President of the Paleobotany Section of the International Union of Biological Sciences and in 1954 first President of the International Organization of Palaeobotany. 1951 to 1960 he was Vice President of the Botanical Society of Stockholm.

He dealt in particular with fossil conifers , about which he wrote his main work The Conifers of the Upper Carboniferous and Lower Permian from 1938 to 1945 . He first described around two dozen genera, e.g. B. Ernestiodendron and Lebachia (both genera from Utrechtiaceae ).

Honors and Membership

In 1946, Florin was elected to the American Academy of Arts and Sciences . In 1947 he became a member of the Swedish Academy of Sciences and received its gold medal in 1964. In 1958 he received the Darwin Wallace Medal from the Linnean Society of London . In 1960 he became President of the Swedish Botanical Society.
