Abstract

The Sorbus arranensis group in Norway consists of five species (S. lancifolia, S. neglecta, S. sognensis, S. subarranensis, S. subpinnata), previously confused with S. arranensis from Scotland. These five species are triploid and apomictic, local or narrowly distributed, originating from hybridization between S. aria s. lato and S. aucuparia. In this nomenclatural survey, the names S. sognensis and S. subarranensis are validly published, and lectotypes are designated for S. lancifolia, S. neglecta and S. subpinnata from the collection of T. Hedlund at UPS. The history of studies in this group is briefly outlined, and conditions for valid publication of each name are reviewed. A complete review of associated data (nomenclature, synonymy, descriptions, line drawings, distributions, chromosome counts, conservation status) is compiled.
