Gunnar Marklund (5 June 1892 in Helsinki – 23 July 1964 also in Helsinki) was a Finnish botanist (taraxacologist and ranunculologist).[1][2][3]
Between 1920 and 1941 he worked as a teacher. In 1937 he received his Ph.D. From 1941 to 1959 he was the curator of the Botanical Museum of the University of Helsinki.[2]
Gunnar Marklund specialised in two difficult apomictic groups, the genus Taraxacum (dandelions) and the Ranunculus auricomus group (goldilock buttercups).[4] He published four monographs, in which he described about two hundred new species,[5] among them for example Ranunculus mendax (Markl.) Ericsson,[6] as well as several smaller papers.
Ranunculus marklundii (Nannf. & Julin) Ericsson [≡ Ranunculus auricomus ssp. marklundii Nannf. & Julin],[12] a goldilock buttercup species known from Sweden and Estonia, and Taraxacum marklundii Palmgr.,[13] a dandelion species described from the Åland Islands,[14] are named in his honour.[15]
