Catalogue and Typifications of New Taxa of Vascular Plants Described by Anders Thiodolf Saelan (1834–1921)

Abstract

Anders Thiodolf Saelan (1834–1921) was a notable non-professional botanist in the late 19th and early 20th century Finland, and was amongst the most diligent writers of his time in the country, authoring five books, 75 articles and 83 communications, for a total of 163 texts. Saelan was particularly known for writing extensive botanical reviews, such as Herbarium Musei Fennici in 1889 and Bibliography of Finnish botanical literature until the end of 1900. He validly published 34 taxa, including two species, Hieracium linifolium and H. pilipes, 6 varieties, 25 forms, and one subform, and introduced 46 names as nomina nuda. Saelan had no concept of type specimens and therefore all his plant taxa need typification, and 28 of those are lectotypified here. In this paper, nomina nuda and the taxa whose type material was not found are also listed, except those of the apomictic genus Hieracium. Most of Saelan's new taxa are nowadays not recognised. Saelan's type collection treated here, as well as his other specimens are deposited at the Botanical Museum (H), Finnish Museum of Natural History, University of Helsinki, Finland.
