This section of six species is confined to the Western Himalaya. Diagnostic characters are "the relatively large achenes (usually 5–6 mm long) with robust dense squamulosity in the uppermost part of achene body, an abrupt achene body transition into subcylindrical to cylindrical, relatively long, more often ± thin cone, usually not numerous, dark, ± unbordered or narrowly indistinctly bordered outer phyllaries, with cornicles near apex, leaves most often slightly brownish green to brownish-purplish green, with relatively narrow, often subhamate lateral segments and very narrow interlobes" (Kirscshner & al. 2020: 206).


"Plants small to medium-sized, plant base usually whitish to brownich arachnoid, tunic ± absent. Leaves most often arachnoid, seldom glabrous, deeply lobed with lobes often subhamate to patent or recurved, petioles narrow, unwinged. Scapes erect during flowering, unbranched, growing from the centre of leaf rosette, arachnoid, particularly below the capitulum. Involucre with a narrowly rounded base. Flowers yellow or deep yellow, florets numerous, ligules usually flat to canaliculate. Outer phyllaries not numerous, usually 8–14 (16), usually narrowly to broadly lanceolate, subappressed to loosely appressed, distally often arcuate, later sometimes arcuate-patent, usually blackish to black-green, unbordered, bordered black, or with indistinct narrow paler borders 0.1–0.3 mm wide, apex usually corniculate, less often flat to callose or horned. Pollen present, stigma dark discoloured , usually blackish. Receptacle glabrous. Achenes large and usually relatively thin, most often 5–6 mm long, very abruptly narrowing into a cylindricalsubcylindrical, rarely basally subconical, thin to medium thick cone usually 1.1–2 mm long, achene body only seldom pale greyish stramineous-brown, usually deep brown, reddish brown, blackish brown, grey-brown or grey, its upper part densely covered with large, often coarse squamules, the uppermost squamules often erect-patent, forming the abrupt transition into the cone, body otherwise with conspicuous, medium dense spinules, the most proximal part often only tuberculate or almost smooth. Beak thin, rarely ± thickened, usually 5–7 mm long, rarely shorter or longer; pappus 5–7 mm long, usually yellowish-brownish or whitish yellow. Sexual or agamospermous."
