Distribution

Al, Ab, N, Ka, St, Ta, Sa, Kl, Oa, Tb, Sb, Kb, Ok, Obo; British Isles ( Sell and Murrell 2006, Tyler 2014), Denmark, Norway, Sweden ( Samuelsson 1954, Schou 2001, Tyler 2017), Baltic countries ( Sennikov 2003 b), western and northern Belarus ( Sennikov 1999 b, Sennikov 1999 c) and northern European Russia ( Schljakov 1989, Sennikov 2000, Sennikov 2006 b, Sennikov 2008 b), limited by Tver Region in the south-east ( Sennikov 2006 c).

Notes

Tyler (2017) rejected the name Hieracium vulgatum in favour of H. triviale , following the neotypification of H. vulgatum made by Greuter ( Greuter and von Raab-Straube 2007).

Diagnosis

Stems 40–60 cm tall. Rosulate leaves lanceolate, base narrowly cuneate, apex rather narrowly triangular, with sparse serrate teeth, rather thin, but rigid, mostly dark-green, with sparse to dense simple hairs 0.8–1.2 mm long and with or without rare to sparse stellate hairs above, on rather long petioles. Cauline leaves similar, 3–5. Phyllaries triangular, with acute apex, 8–10 mm long, grey-green, with sparse to dense black-based simple hairs 1 (1.5) mm long, rare to rather dense glandular hairs 0.2–0.5 (0.7) mm long and sparse to dense appressed stellate hairs on the surface and along a broad stripe on the margins, apex without ciliae. Synflorescence branches with solitary to sparse simple hairs, very rare glandular hairs 0.2–0.3 mm long and stellate hairs. Styles with black papillae. Ligules glabrous.
