Hieracium linifolium Saelan ex Lindeb.

Native status

Native. Open rocks.

Distribution

Ab, N, Oa. Likely endemic to Finland, although reported elsewhere due to the expanded species concept ( Johansson 1929, Schljakov 1989, Sennikov 2003 b).

Diagnosis

Stems 40–60 cm tall. Basal leaves 1–2, much reduced, present at anthesis; cauline leaves 10–15, evenly distributed along the stem, very long below and gradually decreasing in size from the basal part of the stem (plants of pyramidal shape), linear to very narrowly ovate-lanceolate, base narrowly cuneate, apex long attenuated, with sparse small teeth, rigid, dark-green, glabrous and with sparse stellate hairs above, sessile. Phyllaries triangular, with acute apex, 9–10 mm long, grey-green, with rather rare dark-based pale rigid simple hairs 1–1.5 mm long, rather dense glandular hairs 0.2–0.5 mm long along the central line and rather rare stellate hairs mostly in the basal part, apex with indistinct ciliae. Synflorescence branches without simple and glandular hairs, with dense stellate pubescence. Styles with discoloured (yellowish) papillae. Ligules glabrous.
