Abstract

Nineteen new, presumably apomictic species of Hieracium sect. Tridentata, namely Hieracium anisodontum, H. bicoloriceps, H. disparifolium, H. ditrichum, H. erectifolium, H. ferox, H. lapsanae, H. luteoviride, H. megaplicatum, H. multifolium, H. paer-haraldii, H. perpendiculum, H. phaeochlorum, H. prasiniceps, H. semirigidum, H. serriolum, H. spinophytoides, H. svensonii, H. xantholineatum, and one species of H. sect. Foliosa, namely H. hesperidifronsare described from Sweden or raised from infraspecific to specific rank. In addition, the previously invalidly published H. melanostigma is validated. Apart from morphological descriptions, illustrations and maps showing the distribution of all species are provided.
