Sweden, Ostergotland, Linkoping, Magistratshagcn , 4 June 1889, H. Dahlstedt (lectotype in S [bottom specimen], designated by Lundevall and Øllgaard 1999: 81; isolectotype in S) .
Description.
Plants small to middle-sized, 10-15(-20) cm tall. Leaves greyish-green, almost glabrous or with few barely visible hairs, approximately (5-)8-12(-15) cm long and (1.5-)2.0-3.0(-4.0) cm wide, usually 3-5 times longer than wide, blades elliptical, with 4-6 pairs of lateral lobes; lateral lobes opposite to remote; lateral lobes of the inner leaves patent and falcate, with a mostly entire or (at lower-positioned lobes) slightly denticulate distal margin, proximal margin usually entire; lateral lobes of the outer leaves triangular, with a mostly entire, convex distal margin; interlobes often crisped; terminal lobe of the inner leaves tripartite, subsagittate, with a somewhat elongated apex, mostly entire at the margins; terminal lobe of the outer leaves triangular, subacute; petioles narrow, unwinged, purple. Scapes as long as or longer than leaves, somewhat hairy, especially just under the capitulum. Capitulum convex, 3.5-4.0 cm in diameter, light yellow, outer strips grey-purple; inner bracts dark, greyish-green, pruinose, corniculate; outer bracts usually 12-14, lanceolate, usually 7-9 mm long, 2-2.5 mm broad, greyish-green/violet, pruinose with a white hyaline margin (0.05-0.1 mm broad), spreading-arcuate and corniculate; stigmas greyish-green, pollen present. Achenes brown-red, with long spinules in the upper part, (3.5-)3.8-4.1(-4.3) mm long (incl. the 0.7-1.0(-1.2) mm long, cylindrical cone), rostrum 6-8 mm long, pappus white.
Flowering period.
April-May.
Habitat.
Species most often found in semiruderal locations, such as sandy and sunny edges of pine forests, paths, cliffs; less often in ruderal habitats (concrete promenades, walls). On the coast of the Baltic Sea ( Gdańsk) we noted this species on the edge of a sandy forest road, accompanied by Achillea millefolium , Agrostis capillaris , Alliaria petiolata , Anthriscus sylvestris , Artemisia vulgaris , Berteroa incana , Hypericum maculatum , Melandrium album , Plantago major , Potentilla argentea , Tanacetum vulgare , Tragopogon pratensis .
Somatic chromosome number.

Species reported from Portugal, Spain, France, Great Britain, Ireland, Corsica, Italy, Switzerland, Belgium, the Netherlands, Denmark, Germany, the Czech Republic, Hungary, Norway, Sweden, Finland, Poland, Latvia and Lithuania ( Van Soest 1957, 1967; Doll 1973b; Tacik 1980; Fedorov 1989; Richards 1992; Dudman and Richards 1997; Lundevall and Øllgaard 1999; Uhlemann 2003; Trávníček et al. 2010; Wendt and Øllgaard 2015).

Notes.
Plant charming, gentle, with tasteful capitulum up to 4 cm in diameter, light yellow ligules, outer bracts spreading-arcuate, greyish-green/violet, pruinose. Leaves regularly lobed, side lobes most often falcate and interlobes often crisped. Species easy to recognise (morphological features of the leaves are highly visible, even for specimens growing in unusual places) (Figs 24 View Figure 24 , 25 View Figure 25 ).
