Hieracium alpinum L.

Native status

Native. Tundra.

Distribution

Finland: Ks, Lkk, Lks, Le, Li; northern and mountainous Norway and Sweden ( Samuelsson 1954), northern and mountainous European Russia ( Samuelsson 1954, Schljakov 1989) including the Urals in the east ( Chepinoga et al. 2024), mountains of Central Europe ( POWO 2025).

According to Mráz et al. (2009), only triploid populations of the species are present in Scandinavia and Finland, whereas diploid populations are restricted to the Carpathians. The diploid and triploid populations are taxonomically indistinct.

Diagnosis

Stems 15–25 cm tall. Basal leaves pale greyish-green, oblong-lanceolate to spatulate, base narrowly cuneate to attenuate, apex narrowly subrotund to subacute, without or with few indistinct teeth or sometimes with small coarse teeth, on a rather long petiole (1 / 2–2 / 3 as long as the lamina), with dense simple hairs 1.5–3.5 mm long above; cauline leaves 1–2, usually strongly reduced. Synflorescence of 1 flowering head. Phyllaries very narrowly triangular to nearly linear, with acute to narrowly attenuated apex, 13–15 mm long, dark-olivaceous, with abundant black-based or dark simple hairs 2–4 mm long, dense glandular hairs 0.2–0.3 mm long and without stellate hairs, apex with some long ciliae. Stems under flowering heads with very dense to abundant simple hairs 2–3.5 mm long, dense stiff glandular hairs 0.3–0.7 mm long and stellate hairs. Styles with yellow papillae. Ligules ciliate.
