Taraxacum philokalos is an intersectional intermediate. It is characterized by achenes with short coarse spinules and a thick subconical to subcylindrical cone, features matching T. sect. Leucantha, the outer phyllaries, in contast, are exhibit the most common pattern of T. sect. Emodensia (Kirschner & al. 2020: 113, 128).A


"Plants small to ± medium-sized, usually 5–15 cm tall. Petiole pink to purple, narrow, unwinged, glabrous; plant base with some brownish hairs, without tunic. Leaves deep mid-green and slightly pruinose, with mid-vein usualy pinkish to purplish, narrowly oblong-linear in outline, usually 6–8 (–12) × 1–2 cm, glabrous, usually pinnatisect, with (3) 4–5 usually asymmetrically distributed lateral segments on each side, segments with broadly flat-triangular, asymmetrical basal part (distally much longer) and a linear to linear-triangular distal part, usually entire, seldom with a single minute tooth, apex acute; interlobes distinct, to 2–3 mm wide, entire or rarely with a single minute tooth; terminal segment elongated, linear-triangular or linear lingulate, entire, acute, usually 1.5–2.5, sometimes to 4 cm long, with usually ± sagittae base, basal lobules often asymmetrical, recurved to almost patent, linear-triangular. Scape brownish green, usually suffused purplish, glabrous, overtopping leaves. Capitulum ca. 1.5–2 cm wide, yellow. Involucre green to dark green, not pruinose, 7–9 mm wide and rounded at base. Outer phyllaries (11) 15–19 (21), not imbricate, ± loosely appressed, some appressed or ± erect, linear-lanceolate to narrowly lanceolate, usually (5–) 6–8 (–9) × 1.5–3 mm, green to grey-green, with a whitish-membranous border (0.2–) 0.3–0.5 mm wide, with a sharp (often purplish) transition into the middle part, margins glabrous, entire (rarely with 1–2 minute teeth), apex usually reddish, with horns in later capitula; inner phyllaries 10–12 mm long, corniculate. Ligules yellow, outer striped grey-purplish to blackish-purple outside, cucullate to canaliculate, inner ligules often subtubular, their teeth ± grey. Stigmas yellowish green, with greyish and hyaline pubescence outside. Anthers polliniferous; pollen grains irregular in size. Achenes light greyish fulvous (unripe light grey or light grey-ochraceous), 4.7–5.4 × 1.0–1.1 mm, body with conspicuous coarse spinules in upper 1/2–2/3 and on the proximal part of the cone, otherwise tuberculate, gradually narrowing into subconical to subcylindrical, thick [0.5–0.6 (–0.7) mm at base, 0.4 (–0.5) mm distally] cone 1.0–1.2 mm long; beak ± thickened, 5–5.5 mm long; pappus 6–6.5 mm long, yellowish. Agamosperm."
