Palmgren studied botany at the University of Helsinki under professor J.P. Norrlin. He graduated (Fil.kand.) in 1906 and obtained his Ph.D. in 1914. He became docent of botany at the University of Helsinki 1916 and professor of botany at the same university in 1928 (from 1938, the first in the special Swedish-language chair of botany). He retired in 1950.〔Collander, Runar (1965) The History of Botany in Finland. With an Appendix on Forest Science by Yrjö Ilvessalo. Societas Scientiarum Fennica Helsinki, 159 pp.〕 == Research == Palmgren worked as a systematic botanist with microspecies of Taraxacum, Hieracium and other genera. As an ecologist, he worked of the nature of plant communities. He supported the ideas of Henry Gleason on the individualistic behaviour of species in community assembly already from the 1920s.〔(A Letter from Henry A. Gleason, written 1952, printed in Brittonia 39: 2 (1987), pp. 205-209. )(doi )〕 Palmgren wrote early accounts on the role of isolation and stochastic events in the distribution of species, while his contemporary biology was largely deterministic.〔Palmgren, A.
