FLORA OF ICELAND elements: Hieracium aquiliforme, hearth hawkweed

Hieracium aquiliforme; the Hearth Hawkweed is taller than the alpine and hillside hawkweeds. Like the hillside hawkweed, it has a few flowerheads at the top of the stem. The bracts have long black glandular hairs and short stellate hairs. The leaves have rather long petioles and the margins large teeth at the base becoming smaller towards the top of the leaf.

On this page I have added a few photo' s all belonging to one plant. This plant resembles the hearth hawkweed but differs too. It has similar stellate hairs but it has long white glandular hairs (glands black earlier or later in developmen?) and smaller bristle-like black hairs. Also the leaves seem to be densely short-haired on the bottom. Therefore it may resemble H. aquiliforme but it most-likely belongs to another microspecies.
It is member of the Asteraceae (syn.: Compositae) family, i.e. daisy family. The Icelandic name of this species is ArinfĂ­fill.
