FLORA OF ICELAND elements: Hieracium spp, a hawkweed species

Hieracium spp; I have added photo's of another hawkweed plant which I could not identify. It is a rather tall species with one leaf along the stem. This one has only simple long hairs on the flowerhead bracts. However just below the flower head the stem is densely covered with stellate hairs. Downwards though, they become increasingly less. Most strikingly is the dense fluff of hairs in the axils of the basal leaves. Just to show that the hawkweeds come in very different appearances if one takes time to focus on details.
It is a member of the Asteraceae (syn.: Compositae) family, i.e. daisy family.
