Hieracium porrigens Almq. ex Elfstr.

Native status

Native. Forest margins.

Distribution

Finland: Al; Scandinavia ( Tyler 2006 e), Baltic countries ( Sennikov 2003 b). As the species is not present in Finland east to the Åland Islands, its report from the neighbouring Russia ( Schljakov 1989) is unlikely correct.

Diagnosis

Stems 40–50 cm tall. Rosulate leaves lanceolate, rhombic-lanceolate or lanceolate-ovate, base broadly cuneate, apex triangular, with numerous coarse teeth, rather thick, with sparse simple hairs 1–1.5 mm long along the margins above, on rather long petioles. Cauline leaves similar, reduced in size, 2–3. Phyllaries broadly triangular, with broadly acute apex, 11 (12) mm long, pale grey-green, with very rare black-based simple hairs 1–1.5 mm long, rather dense glandular hairs 0.5–0.8 (1) mm long and rather dense stellate hairs throughout, apex with a large coma of abundant ciliae. Synflorescence branches with rare simple hairs, dense glandular hairs 0.2–0.4 (0.5) mm long and stellate hairs. Styles with dark papillae. Ligules glabrous.
