amphigenous colony of Ramularia hyphomycetous anamorph of Mycosphaerella hieracii causes spots on live leaf of Hieracium alpinum

The type of Hieracium trigonophorum Oskarsson is probably conspecific with that of H. alpinum.

Plants 10–15(–25+) cm. Stems proximally piloso-hirsute (hairs 3–5+ mm), stellate-pubescent, and stipitate-glandular, distally piloso-hirsute (hairs 3–5+ mm), stellate-pubescent, and stipitate-glandular. Leaves: basal 5–13+, cauline 0(–2+); blades spatulate to elliptic or narrowly lanceolate, 20–80 × 6–20+ mm, lengths 2–8+ times widths, bases cuneate, margins usually entire, rarely dentate, apices rounded to acute, faces piloso-hirsute (hairs 1–3+ mm). Heads borne singly or 2+ in corymbiform arrays. Peduncles piloso-hirsute, stellate-pubescent, and stipitate-glandular. Calyculi: bractlets 5–8+. Involucres ± hemispheric, 13–18 mm. Phyllaries 13–21+, apices acute to acuminate, abaxial faces piloso-hirsute and stipitate-glandular. Florets 80–120+; corollas yellow, 12–15 mm.

Hieracium angmagssalikense Omang

Hieracium alpinum, the alpine hawkweed, is a Eurasian plant species in the tribe Cichorieae within the family Asteraceae. It is native to Europe, and has also been found in Greenland.

Hieracium alpinum is an herb up to 25 cm (9.8 in) tall, with leaves mostly in a rosette at the bottom. Leaves are lance-shaped, up to 8 cm (3.1 in) long. One stalk will usually produce only one flower head, though occasionally 2 or 3. Each head has 80-120 yellow ray flowers but no disc flowers.
